Based on the argument that legitimacy and competition are two important forces in foreign market entry decisions, we hypothesize that an MNC’s market entry decisions are influenced by its own prior entry and prior exit decisions and those of other MNCs. We examine this general proposition at four levels of analysis: the host country, global industry (an industry that spans host countries), local industry (an industry that is separately defined within each host country), and parent firm level. Our analysis of a panel data of over 4000 market entry decisions that were made by Japanese MNCs shows that an MNC’s market entry decision has a stronger inverted U-shaped relationship with the prior entry and exit decisions of other MNCs at the local industry level than the prior entry and exit decisions of other MNCs at the host country and global industry levels. We also find that both the prior entry and prior exit decisions of an MNC have a marginal influence on its own subsequent market entry decisions at the parent firm level.

Most research has depicted the investment behavior of firms as being driven by a primarily economic rationale, as they seek to increase market power, gain access to resources, and minimize transaction costs (Buckley and Casson, 1976; Rugman, 1981; Casson, 1982; Hennart, 1982; Teece, 1986). Although firms make economically rational choices that are motivated by ‘efficiency and profitability’, they also make normatively rational choices that are motivated by ‘historical precedent and social justification’ (Oliver, 1992: 701). More recent research has emphasized the sociological perspective, and has examined the legitimating effects of the foreign market entry decisions of firms (Guillén, 2002). The sociological perspective, which acknowledges the importance of market competition, assumes that the behavior of firms is nested Interdependent behavior in foreign direct investment Christine M. Chan et al 643 within a highly structured historical and cultural context, and that firms lack information about the efficiency and effectiveness of their strategies ex ante (Meyer and Zucker, 1989). Under this condition of uncertainty, firms increase their chance of survival by following the organizational practices or strategies of other firms that are perceived to be legitimate (DiMaggio and Powell, 1983; Scott, 2001). In the case of foreign market entry, firms that are less familiar with a foreign market tend to refer to and imitate the actions of other firms that operate in the same market, because of the legitimacy of highly visible entry decisions (Guillén, 2002). To extend this line of research, our study examines interdependent foreign market entry decisions between and within MNCs. Specifically, we examine two issues: the extent to which the prior entry and exit decisions of other MNCs influence the subsequent entry decisions of an MNC, and the extent to which an MNC’s own prior entry and exit decisions influence its subsequent entry decisions. This study differs from previous research in two ways. First, it focuses on interdependent market entry decisions in multi-level institutional environments: host country, global industry (an industry that spans host countries), local industry (an industry that is separately defined within each host country), and parent firm (a firm with a network of foreign operations that are under common control and ownership). Several studies have examined the interorganizational effects of foreign market entry in the context of buyer–supplier relationships (Hennart and Park, 1994; Martin et al., 1998) and business groups (Guillén, 2002). The level of analysis in these studies, however, is limited to the context of a particular industry or a single host country. Given that the foreign operations of MNCs are embedded in multiple levels of institutional environments with different sources of authority and different sets of legitimating requirements to which they must conform (Sundaram and Black, 1992; Ghoshal and Westney, 1993; Kostova and Zaheer, 1999), an analysis of the multiple-level influences of institutional environments will provide a more comprehensive understanding of interdependent foreign market entry behavior. The second way in which this study differs from others is that it focuses on both prior entry and prior exit decisions as the key determinants of foreign market entry decisions. Although recent studies have made significant contributions to explaining how prior entry decisions influence subsequent market entry decisions (Guillén, 2002), they have ignored the effects of prior exits, as they assume these effects to be constant. To understand the dynamics of foreign market entry strategy, we need to take into account the processes of both market entry and exit. Our study is novel in that it addresses the questions of the relevant levels of analysis for the investigation of interdependent foreign market-entry behavior, and also the extent to which the prior entry and exit decisions of an MNC and other MNCs influence subsequent foreign market entry decisions. We focus on foreign market entry through foreign direct investment, rather than through arm’s length contractual modes, such as licensing and exporting or importing. Building on institutional and organizational ecology theory, we argue that the behavior that is associated with foreign market entry represents an organizational response that is executed to selectively enter a host country, global industry, or local industry markets in which the form of market entry is perceived to be legitimate. To test our arguments, we use a sample of 4349 subsidiaries that were established by eight large Japanese electronics MNCs over the period of 1988– 1998 that operate in 110 countries, 18 global industries (two-digit SIC), and 1980 local industries. The use of panel data that consists of 156,451 spells allows us to examine both the effects of prior entry and prior exit decisions on subsequent foreign market entry decisions at the host country, global industry, local industry, and parent firm levels. Literature review Research in different disciplines has sought to explain when and why firms invest in foreign countries. Industrial organization economists view foreign direct investment as the strategic response of firms to both domestic competition and opportunities in foreign countries. They suggest that firms engage in foreign direct investment to gain greater market power, especially when they possess monopolistic advantages over local competitors that outweigh the disadvantages of being foreign (Hymer, 1976), when they can eliminate oligopolistic competition through alliances with – or acquisitions of – local firms (Caves and Mehra, 1986), and when their close rivals initiate foreign direct investment in a host country (Knickerbocker, 1973; Flowers, 1976; Graham, 1978; Yu and Ito, 1988). Transaction cost economists view foreign direct investment as an organizational response to imperfections in the intermediate Journal of International Business Studies Interdependent behavior in foreign direct investment Christine M. Chan et al 644 goods, knowledge and capital markets. They argue that firms use foreign direct investment to minimize market transaction costs by internalizing transactions and other interdependent economic activities across borders (Buckley and Casson, 1976; Rugman, 1981; Hennart, 1982). Scholars of trade theory, economic geography and, more recently, strategic management view foreign direct investment as a platform from which firms can gain access to location-specific assets, such as factor endowments, location-based externalities, and strategic assets that are owned by other firms in particular regions and countries (Dunning, 1995; Kuemmerle, 1999). Although most of the early studies assume the foreign market entry of a firm to be an independent decision, Knickerbocker (1973) pioneered the notion of interdependent foreign market entry behavior that is modeled on the oligopolistic reaction theory. Underlying this theory is the proposition that the investment decisions of pioneering firms are imitated by their close competitors in the same industries, which is a competitive response to prevent the pioneering firms from monopolizing the market (Flowers, 1976; Yu and Ito, 1988). More recent studies have provided evidence that the likelihood that a firm will enter a market is influenced by the previous decisions of other firms on market entry in the context of the foreign expansion of suppliers and business groups (Martin et al., 1998; Guillén, 2002). In addition to the influence of the previous actions of other firms, some studies have found that firms follow their own previous investment decisions, which are a coherent part of their international strategy (Kogut, 1983; Kogut and Chang, 1991; Chang, 1995; Barkema et al., 1996). These studies typically suggest that the foreign investment decisions of firms are critically influenced by both their own prior investment decisions and the prior investment decisions of other firms. Although previous studies provide economic explanations of interdependent foreign market entry behavior, they leave little scope for the sociological explanations that underlie this behavior. Given that a firm’s choice of action is influenced by economic rationality and normative rationality (Oliver, 1997), the motivation to engage in foreign direct investment should rest not only on an economic rationale, but also on social considerations. One notable exception that pays explicit attention to the sociological rationale of interdependent foreign market entry behavior is Journal of International Business Studies Guillén’s (2002) study. Drawing on the cognitive view of institutional theory, he suggests that the entry of other firms into a foreign market enhances the legitimacy of such a market entry, and thereby encourages subsequent market entries by new firms. The basic assumption that underlies this argument is that firms operate within a social framework of values, norms, and assumptions about acceptable economic behavior. As economic activities are socially embedded (Granovetter, 1985), and are structured in unique institutional environments within both industries and countries (North, 1990; Henisz, 2000a, b; Aoki, 2001; Scott, 2001), firms make normatively rational choices by imitating the market entry decisions of other firms that are considered to be legitimate. In extending this stream of research, this study develops a conceptual model of interdependent foreign market entry behavior using legitimacy as a key concept in the model. Theoretical development Legitimacy is defined as ‘a generalized perception or assumption that the actions of an entity are desirable, proper, or appropriate within some socially constructed system of norms, values, beliefs, and definitions’ (Suchman 1995b: 574). The bases of legitimacy vary with the regulative, normative, and cultural-cognitive pillars of institutional theory (Scott, 2001). The regulatory view emphasizes conformity to rules and laws, the normative view emphasizes normative support that results from a congruence in values, and the cultural-cognitive view emphasizes the adoption of a common frame of reference (Scott, 2001). Although there are different mechanisms to achieve legitimacy, we focus here on the culturalcognitive view of institutional theory. Firms pursue legitimacy because they require social acceptance and credibility to succeed and survive in challenging environments (DiMaggio and Powell, 1983; Aldrich and Fiol, 1994; Scott, 1995; Scott et al., 2000). In uncertain situations, firms can gain legitimacy by imitating the organizational structure that is perceived to be appropriate to their organizational field, or by employing the orthodox organizational practices that are adopted by a large number of other firms in their institutional environment (Meyer and Rowan, 1977; DiMaggio and Powell, 1983; Tolbert and Zucker, 1983; Scott, 1995; Suchman 1995a, b; Haunschild and Miner, 1997; Henisz and Delios, 2001; Chan and Makino, 2002; Kostova and Roth, Interdependent behavior in foreign direct investment Christine M. Chan et al 645 2002; Lu, 2002; Yiu and Makino, 2002). The general belief is that the prevalence of an organizational form enhances its legitimacy in the eyes of the legitimating actors, who determine whether it is desirable, proper, and appropriate within a given institutional context. When legitimating actors are more familiar with an organizational form, they perceive the kinds of activity that are performed within that form to be legitimate (DiMaggio and Powell, 1983; Tolbert and Zucker, 1983; Orru et al., 1991). Legitimacy gives firms the ability to perform their activities with relatively less constraint, to acquire the resources that they need to sustain their operations in competitive markets, and to fend off challenges to their right to provide specific products or services (Meyer and Rowan, 1977; DiMaggio and Powell, 1983; Suchman 1995b; Ahlstrom and Bruton, 2001; Scott, 2001). This argument runs parallel to the institutional bandwagon theory, which states that an increase in the number of firms using a particular type of innovation causes other firms to adopt the same innovation to avoid a loss of legitimacy or the support of their stakeholders (Abrahamson and Rosenkopf, 1993). Organizational ecologists have also embraced the cultural-cognitive conception of institutions, and have found that at low levels of organizational density (or the number of organizations of a given form), any growth in density enhances the legitimacy of the organizational form, and therefore increases the founding rate (Carroll and Hannan, 1989). In the case of foreign market entry, firms behave not only strategically, by increasing their economic rents, market power, or transactional efficiency, but also socially, by mimicking the decisions of other firms in the same market to cope with market uncertainty and to gain legitimacy (Guillén, 2002, 2003). Firms perceive greater uncertainty about the outcome of foreign market entry when they lack the information and the cognitive capacity that are required to estimate present and future market conditions in the host country (Johanson and Vahlne, 1977). When little prior information is available about the idiosyncrasies of a local market and the costs and benefits of expansion into that market, firms run a greater risk of making irreversible mistakes when choosing markets to enter (Mitchell et al., 1994). To mitigate the chance of business failure that arises from market uncertainty, firms tend to observe and follow the prior entry decisions of other firms that share similar attributes or belong to the same cognitive category (Haveman, 1993; Greve, 2000; Guillén, 2002). Furthermore, firms that enter a local market are exposed to different sources of authority and different sets of legitimating requirements, which are imposed by legitimating actors, such as the government of the host country or local activist groups (Sundaram and Black, 1992; Ghoshal and Westney, 1993; Kostova and Zaheer, 1999). When there are few foreign establishments in a local market, these legitimating actors are unable to bestow legitimacy on new foreign operations because of a lack of understanding about the nature of these operations (Dobrev, 2001). Foreign firms may also lack the contextual knowledge to respond to local legitimating requirements, and may therefore be less able to gain legitimacy from, or negotiate with, legitimating actors (Henisz, 2000b).1 To make sense of legitimacy requirements, foreign firms tend to observe the behavior of other foreign firms because legitimating actors judge the legitimacy of new foreign operations by referring to the legitimacy of other foreign operations that belong to the same group when both the foreign firms and the legitimating actors operate under conditions of bounded rationality (Kostova and Zaheer, 1999). To avoid legitimacy problems, firms often choose to enter a local market that other similar foreign firms have already entered, because an increase in the number of foreign entrants in a market not only heightens the visibility of foreign operations, but also enhances the legitimacy of establishing foreign operations in that market (Guillén, 2002). With this enhanced legitimacy, new entrants find it easier to overcome resistance from local stakeholders who are adversely affected by the establishment of foreign operations (Guillén, 2002). The prior entry decisions of other foreign entrants in a market therefore serve as a signal to potential entrants that the market is attractive because of the enhanced legitimacy of foreign market entry. The propensity to imitate the entry decisions of other firms, however, may decrease beyond a certain threshold, because the continued acceptance of legitimate organizational actions or behavior cannot be presumed (Zucker, 1988; Oliver, 1992; Scott, 1995, 2001; Ang and Cummings, 1997). Firms may not continually reproduce taken-for-granted organizational actions or behavior if they change their perceptions of what constitutes legitimate organizational actions or behavior (Oliver, 1992; Scott, 2001). The weakening of organizational consensus on the value of legitimate organizational actions or behavior can be a Journal of International Business Studies Interdependent behavior in foreign direct investment Christine M. Chan et al 646 result of changes in the internal and external environments of a firm, such as the introduction of new technology (Barley, 1986), a change in institutional logic (Scott et al., 2000), a change in industrial regulations (Fligstein, 1990), a shift in cultural beliefs (Frank et al., 1999), or increased competition among firms (Oliver, 1992; Greenwood and Hinings, 1996). The tendency to follow the market entry behavior of other firms may mount to the top when firms observe many other foreign firms entering the same market. A large number of new entrants serves as a signal of increased competition to both potential entrants and entrenched firms, and means that the competition for resources (for example, skilled labor and access to local distribution and supplier networks) and customers will inevitably be intensified (Mitchell et al., 1992, 1994). The increase in the intensity of market competition not only drives entrenched firms to attempt to create entry barriers to new entrants, but also deters potential entrants from establishing foreign operations in the market. In organizational ecological terms, when the organizational density becomes relatively high, the legitimation process gives way to a competitive process as the number of firms of a given form increases (Carroll and Hannan, 1989; Hannan and Carroll, 1992). Following this logic, we expect that the tendency to imitate the foreign market entry decisions of other firms in a market will decrease beyond a certain threshold as the number of new entrants in the market increases. Although recent studies have made significant contributions to the examination of mimetic behavior in the context of alliance formation and foreign expansion (Garcia-Pont and Nohria, 2002; Guillén, 2002, 2003), their focus has been on either the proportion of prior entries or the density of firms as the measure of imitation. However, the dynamics of foreign market entry represent a process of both entry into and exit from a market. Studies that examine the effects of prior entry may underestimate the influence of prior exit on the imitative entry behavior of a firm, because the exit of other firms sends a signal to potential entrants that the resources and customers that were previously tapped by the exiting firms have been released, and can now be taken over by new entrants (Delacroix and Carroll, 1983; Delacroix et al., 1989; Messallam, 1998). As new entrants can claim the finite resources and customer base that have been released by the exiting firms, prior exits mitigate the intensity of competition and therefore Journal of International Business Studies induce new entrants to capture the potential of a market. However, firms may change their perceptions of foreign market entry behavior as a result of changes in the perceived instrumental value of organizational activities (Oliver, 1992). The perceived value of entering a market may become questionable when firms observe a large increase in the number of foreign operations exiting a given market, as a large number of exits serves as a signal that the market is too hostile for new entrants (Delacroix and Carroll, 1983; Messallam, 1998). The hostility of a market may be due to foreign operations being regarded as an illegitimate organizational form (Kostova and Zaheer, 1999). When a hostile market does not offer sufficient benefits for new entrants to cover the costs of foreign market entry, firms find the market less attractive for the establishment of foreign operations, which thus deters entry. In contrast to previous studies, we examine the impact of both the prior entry and prior exit of other MNCs on an MNC’s entry behavior, and suggest two sets of hypotheses. First, we propose that the number of prior entries that have been made by other MNCs in a market has an inverted Ushaped relation to an MNC’s decision to enter the same market. Our main argument is that MNCs are likely to follow the market entry decisions of other MNCs, because prior entrants enhance the legitimacy of foreign operations in a local market, which thus makes the market more attractive for investment. However, when the number of entrants in a market reaches a certain high level, any further increase in the number of entrants sends a signal of increased competition, and thereby discourages any further MNCs from entering the market. We also propose that the number of prior exits that have been made by other MNCs from a market has an inverted U-shaped effect on an MNC’s decision to enter the same market. The rationale behind this proposition is that exits from a market mitigate the extent of competition in a market, and therefore create space for new entrants. However, large numbers of exits from a market signal the hostile nature of the market, and thus discourage MNCs from entering it. The argument that is discussed here applies not only to interdependent foreign market entry behavior among MNCs, but also to interdependent foreign market entry behavior within an MNC, because the market entry decisions of an MNC are also influenced by its own market entry decisions that were made in the past. Our main argument is Interdependent behavior in foreign direct investment Christine M. Chan et al 647 that, when facing uncertainty in doing businesses in foreign countries, firms tend to repeat past routines and standard operational activities because these approaches have been legitimized over time (Porter, 1990). Many organizational activities are supported by the shared social belief systems, traditions, and corporate culture of a firm (Berger and Luckmann, 1967; Zucker, 1983; Oliver, 1992; Scott, 2001). These organizational activities are so taken for granted that firms may not question their appropriateness or usefulness (Oliver, 1997). Organizational members within firms therefore develop a social consensus on the propriety of re-enacted activities that is resistant to change (Zucker, 1983; Ashforth and Fried, 1988; Weick, 1995; Scott, 2001). However, we argue that the tendency of MNCs to repeat their own previous market entry decisions may decrease beyond a certain threshold. Firms may not be willing to reproduce previously legitimate organizational activities and actions because changes in their internal institutional environments cause them to reconsider the value of what were once considered to be legitimate organizational activities and actions (Oliver, 1992). The impetus for change may be poor firm performance, incongruence between social and economic objectives, or increased internal disagreement over appropriate organizational processes or practices (Oliver, 1997). In the case of foreign market entry, MNCs may be less likely to repeat their prior entry decisions when they recognize that the internal resources that are used to support such entries have reached a limit. These internal resources include capital, knowledge, technology, human resources, and expertise (Gupta and Govindarajan, 1991; Rosenzweig and Singh, 1991). A large number of prior entries of an MNC implies that there are reduced available internal resources to support any subsequent market entries, which thereby discourages the MNC from repeating its own prior entry decisions. We also argue that the exit of the foreign subsidiaries of an MNC from markets implies a release of internal resources. As the foreign subsidiaries of an MNC form part of a large organizational system (Delacroix, 1993), the exits of foreign subsidiaries allow the MNC to redeploy the released internal resources to support subsequent entries into new markets. However, a further increase in the number of exits implies that the foreign subsidiaries may not have received the support of their stakeholders. The foreign subsidiaries of an MNC are subject to different pressures in the local environments in which they operate (Rosenzweig and Singh, 1991; Westney, 1993; Kostova and Zaheer, 1999). Each local environment is for or against a foreign operation based on its own set of requirements (Rosenzweig and Singh, 1991). A large number of exits of foreign subsidiaries sends a signal that the MNC as a whole may be unable to adapt to and maintain legitimacy in all of its local environments, which thereby deters any further attempts to enter new markets. We therefore propose that the number of prior entries and exits that are made by an MNC has an inverted Ushaped relation to the MNC’s own subsequent decisions to enter a market. The conceptual model that is used in this study is presented in Figure 1. Although our proposed model is akin to the density dependence model of organizational founding (Carroll and Hannan, 1989; Hannan and Freeman, 1989; Hannan and Carroll, 1992; Carroll et al., 1993; Hannan, 1997), in that both models focus on legitimacy and competition as the key determinants of market entry,2 our model differs from the density dependence model in a significant way. The density dependence model treats an increase or a decrease in the aggregated number of firms (or the density) as a proxy for legitimacy and competition, and implicitly posits that all prospective entrants make entry decisions primarily by observing the ‘stock’ (or absolute number) of incumbents in a focal market. Our model posits that prospective entrants make entry decisions primarily by observing the ‘flow’ of entries and exits that have previously been made in a focal market. We focus on the flow, rather than the stock, because the use of the density measure obscures the independent effects of prior entries and prior exits on subsequent entries (Delacroix et al., 1989). Thus, to provide a more detailed analysis of the dynamic processes of foreign market entry decisions, our model specifies the effects of prior entries and exits on foreign market entry. Our study also contributes to the understanding of the multi-level effects of legitimacy and competition on foreign market entry. Although legitimacy and competition represent two very important forces in foreign market entry decisions, previous studies have paid little attention to the choice of appropriate levels of analysis, or to what specific firms MNCs tend to follow. We take other MNCs from a given home country to be the reference group for an MNC from the same home country (Martin et al., 1998; McKendrick, 2001), as foreign firms tend to pay more attention to the behavior of other entrants from their home country than to Journal of International Business Studies Interdependent behavior in foreign direct investment Christine M.

In addition, an MNC consists of multiple foreign subsidiaries that operate in multiple industries in multiple host countries, and hence faces diverse internal and external institutional environments. A related issue is the appropriate institutional environment levels at which foreign market entry behavior occurs. Based on the regulative, normative, and cultural-cognitive pillars of the institutional environment that are suggested by Scott (1995), we consider host country, global industry, local industry, and parent firm to be the relevant levels of analysis for the study of foreign market entry behavior. The regulatory pillar emphasizes regulating, monitoring, and sanctioning activities; the normative pillar places an Journal of International Business Studies emphasis on the preferred values and shared norms; and the cultural-cognitive pillar stresses the socially constructed common framework of meaning. Hence a key question to be addressed is whether or not the market entry decisions of MNCs are more likely to be influenced by the prior entry and prior exit decisions of other MNCs in the same host country, global industry, or local industry; or are more likely to be influenced by their own prior investment decisions. In the next section, we develop hypotheses on the influence on an MNC’s foreign market entry decisions of the prior market entry and exit decisions of that MNC at the parent firm level, and the same decisions of the other specified MNCs in the reference group at the host country, global industry, and local industry levels. Interdependent behavior in foreign direct investment Christine M. Chan et al 649 Hypotheses Host country Host countries constitute the external institutional environments in which foreign entrants are embedded, and consist of various authorities and stakeholders, including states, local activist groups, customers, supplier groups, labor unions, and national trade associations, all of which constitute institutional arrangements that shape economic activities and bestow legitimacy on foreign firms. Although institutional arrangements within countries are relatively stable over time, they differ across countries, because each country has its own regulatory, normative, and cultural-cognitive institutions (Westney, 1993; Murtha and Lenway, 1994). Studies that embrace the regulatory perspective show that countries differ in their national rules and regulations, federal systems, and governance mechanisms (North and Thomas, 1973; Skocpol, 1979; Cole, 1989; Delacroix, 1993; Ring et al., 2005). Recent research suggests that variation in rules and policies leads to variation in innovative and mimetic behavior (Mahmood and Rufin, 2005), and the market entry behavior of firms across countries (Rodriguez et al., 2005). Theorists who highlight the normative elements of institutions suggest that countries differ in their development of value systems, normative frameworks, and standards. In a study of the diffusion of managerial ideologies in the US, Spain, Germany, and the UK, Guillén (1994) found that diffusion patterns vary across countries, because managerial ideologies receive different amounts of support from professional groups and state agents. Research on the cultural-cognitive perspective suggests that each country has its own conceptions that are shaped through social interaction within the country. Dobbin (1994) found differing cultural belief systems that were constructed to support societal policy strategies in the United States, England, and France. In their study of the car industries of South Korea, Taiwan, Spain, and Argentina, Biggart and Guillén (1999), focusing on both normative and cultural-cognitive institutions, provide evidence that each country has its own distinctive institutional pattern of organization that promotes the development of its own model of car manufacturing. As institutions are often country specific (Rosenzweig and Singh, 1991; Whitley, 1992), the distinctive rules of the market and business recipes shape the perceptions and judgments of the host country of the legitimacy of foreign operations (Westney, 1993; Kostova and Zaheer, 1999). As each country has its own set of legitimating requirements for foreign operations, MNCs that encounter contextual uncertainty in a host country tend to follow the prior market entry decisions of other MNCs in the host country, because the increasing presence of foreign subsidiaries enhances the legitimacy of entry into such a market. Legitimacy not only alleviates the opposition that arises from local government and labor unions (Kostova and Zaheer, 1999), but also gives a signal to other foreign entrants that they can enjoy the benefits of market entry. However, a greater number of foreign subsidiaries of other MNCs in the same host country market intensifies market competition, and we therefore expect that the tendency of MNCs to imitate the prior entry behavior of other MNCs in a host country weakens when many other MNCs enter the same host country market. We also expect that the prior exits of foreign subsidiaries of other MNCs from a host country market alleviate the extent of competition among MNCs, because each exit represents a release of resources that triggers new MNCs to invest in the market. However, a high level of exits from a host country signals a hostile market, and thereby discourages subsequent market entry. Thus, we hypothesize the following. Hypothesis 1a: The founding of a subsidiary of an MNC in a host country has an inverted U-shaped relationship with the number of prior entries of subsidiaries of other MNCs in the same host country. Hypothesis 1b: The founding of a subsidiary of an MNC in a host country has an inverted U-shaped relationship with the number of prior exits of subsidiaries of other MNCs from the same host country. Global industry An industry is taken to mean an external institutional environment in which firms offer similar products or services and collectively develop common standards and legitimate ways of doing businesses through continuous interaction with customers and suppliers (Scott, 1995).3 Although some governance systems and widely held cultural beliefs influence firms in various industries, there are substantial differences in the mechanisms that govern individual industries and in the institutional logic that guides activities within an industry (Scott, 2001). Previous research has found that Journal of International Business Studies Interdependent behavior in foreign direct investment Christine M. Chan et al 650 governance arrangements differ greatly across industries, because the state may manipulate regulatory policies differently in different industries, authorities may impose common standards or rules on firms in the same industry, and actors may engage in a process to sustain a particular type of governance structure in a given industry (Wilks and Wright, 1987; Campbell and Lindberg, 1990; Oliver, 1997). Industries also differ in the institutional logic that provides guidelines on carrying out business and defines the taken-for-granted practices that predominate in the industry or field (Powell and DiMaggio, 1991; Oliver, 1997). As industries vary in their governance structures, economic policies, and institutional logics, industry incumbents have their own perceptions of what constitutes legitimate business practice and behavior, which in return affect the mimetic behavior of the firms within that industry. Studies on mimetic isomorphism have found that, in uncertain situations, firms tend to pursue legitimacy by imitating the actions of other firms in the same industry, some examples of which are the diffusion of civil service reform (Tolbert and Zucker, 1983), the adoption of the hospital matrix management design (Burns and Wholey, 1993), the geographical expansion of commercial banks (Haveman, 1993), the adoption of new formats by radio stations (Greve, 1996), the use of investment bankers as advisors on acquisition (Haunschild and Miner, 1997), and the establishment of wholly owned plants (Guillén, 2003). A different but related perspective is the theory of industrial organization economics, which suggests that industry is an appropriate level of analysis for understanding the behavior and performance of firms, because the structure of a given industry constrains the behavior of the firms within it and leads to differences in firm performance between industries (Bain, 1959; Porter, 1980). Research on oligopolistic imitation also shows that the actions and reactions of close rivals are highly interdependent, as the market entry of a firm into a new industry prompts its competitors to match the firm’s move into that industry (Knickerbocker, 1973; Yu and Ito, 1988). These two separate lines of research generally support the argument that firms within the same industry tend to recognize one another’s presence and follow one another’s actions. In the context of global competition, MNCs compete in global industries that span national borders (Porter, 1990). As they spread their activities across countries to offer relatively standardized products and Journal of International Business Studies services worldwide, their competitive positions in one country are influenced by the position of other MNCs in other countries (Porter, 1990). Global industries, therefore, are institutional environments in which MNCs tend to emulate one another’s actions (Westney, 1993). Extending the argument to the case of foreign market entry, we argue that, in uncertain situations, the market entry decisions of MNCs in a global industry are influenced by the prior entries into and exits from the same global industry by other MNCs. Thus, we hypothesize the following: Hypothesis 2a: The founding of a subsidiary of an MNC in a global industry has an inverted Ushaped relationship with the number of prior entries of subsidiaries of other MNCs in the same global industry. Hypothesis 2b: The founding of a subsidiary of an MNC in a global industry has an inverted Ushaped relationship with the number of prior exits of subsidiaries of other MNCs from the same global industry. Local industry Institutional environments vary not only between global industries, but also between industries within a host country, as each domestic industry has its own national arrangements that govern ‘the way business is done in an industry in a particular country’ (Zaheer and Zaheer, 1997). National industry arrangements derive from national regulatory conditions, from the industrial policy of the government (Murtha and Lenway, 1994), and from social relations between the local protagonists (buyers, suppliers, legislative and political authorities, and research institutes) within and between industries in a country (Porter, 1990; Kogut, 1991; Bartholomew, 1997). Local industries therefore form institutional environments in which different firms offer similar products, satisfy similar customer needs, and face a common set of legitimating pressures that drive them to behave similarly (Koh et al., 1990; McKendrick, 2001). A more recent study provides evidence that firms tend to mimic the behavior of other firms that belong to a specific strategic group within an industry (local mimetism), rather than mimicking the behavior of all of the firms in an entire industry (global mimetism) (Garcia-Pont and Nohria, 2002). The findings from this study suggest that mimetic processes are better specified at the local level than at the global level, Interdependent behavior in foreign direct investment Christine M. Chan et al 651 as firms do not respond homogeneously to the external environment. Organizational ecologists also suggest that the processes of legitimation and competition vary at different levels of analysis, even within the same industry (Carroll and Wade, 1991; Swaminathan and Wiedenmayer, 1991; Hannan and Carroll, 1992; Baum and Singh, 1994; Hannan et al., 1995; Lomi, 1995; Hannan, 1997). For example, in studies that use density dependence models of organization to investigate American brewers, Italian rural cooperative banks, and Tokyo banks, founding rates are found to be greater when the institutional population is narrowly defined than when it is broadly defined (Carroll and Wade, 1991; Lomi, 1995, 2000; Greve, 2002). The findings from these studies show that firms tend to be responsive to localized processes of legitimation and competition, because many firms rely heavily on their immediate institutional and competitive environments for support and resources. Several empirical studies also provide support for stronger competitive effects at the local or regional level, which indicates that firms compete more intensely in the local environment (Baum and Singh, 1994; Hannan et al., 1995; Lomi, 1995; Baum and Oliver, 1996; Bigelow et al., 1997). It is thus plausible to argue that the influences of the prior market entry and exit decisions of other MNCs in a local industry are stronger than the same decisions at the host country and global industry levels, because firms are more sensitive to the signs of attractive and hostile markets at the local industry level than at the host country and global industry levels. We therefore expect that MNCs monitor more closely the foreign market entry and exit decisions of other MNCs that enter the same industry within a host country, rather than homogeneously mimicking the behavior of other unspecified MNCs in their host country and global industry. Thus, we hypothesize the following: Hypothesis 3a: The founding of a subsidiary of an MNC in a local industry has a stronger inverted U-shaped relationship with the number of prior entries of the subsidiaries of other MNCs in the same local industry than with the aggregate number of prior entries of other MNCs in a host country and global industry. Hypothesis 3b: The founding of a subsidiary of an MNC in a local industry has a stronger inverted U-shaped relationship with the number of prior exits of the subsidiaries of other MNCs from the same local industry than with the aggregate number of prior exits of other MNCs from a host country and global industry. Parent firm MNCs not only follow the actions of other MNCs in their external institutional environments, but also take into account their own decisions that they have made in the past. Parent firms, which form an internal institutional environment in which their subsidiaries are embedded, define the appropriate ways of acting and develop the rules that justify their past behavior and guide their current actions (Ashforth and Fried, 1988; Westney, 1993; Weick, 1995; Kostova and Zaheer, 1999; Scott, 2001). To maintain consistency within their internal institutional environments, MNCs impose coercive pressure on their foreign subsidiaries to adopt mandated organizational practices (Kostova and Roth, 2002), recruit new employees who share the same interpretive and normative frameworks as current employees to support ongoing activities and behavior (Kilduff, 1993), and persist in adopting the taken-for-granted mode of entry that has been used in the past (Lu, 2002; Yiu and Makino, 2002). In the case of early foreign market entry, MNCs face primary uncertainty that arises from a lack of familiarity with the local institutional environment, such as local practices and preferences, which may not be easily interpreted or observed (Koopmans, 1957; Sutcliffe and Zaheer, 1998; Kostova and Zaheer, 1999). Under such uncertain conditions, firms tend to replicate the routines and practices that they have enacted previously and with which they are familiar. These past actions and practices will be reinforced unless a critical disruption occurs (Kelly and Amburgey, 1991; Amburgey and Miner, 1992). Following this line of argument, we expect that the prior market entries of the subsidiaries of MNCs in a focal market stimulate their subsequent market entry decisions, because their entry strategies are legitimized over time. However, the process of repetitive entry slows down when the internal resources that are available to support foreign operations reach their limit. In contrast, the prior exits of foreign subsidiaries release the resource constraints within an MNC, and with more resources available, MNCs can redeploy their existing resources and reinvest them in other foreign subsidiaries. Further exits of foreign subsidiaries, however, signal that the foreign operations of the MNC may not be supported by its stakeholders, which thus discourages the Journal of International Business Studies Interdependent behavior in foreign direct investment Christine M. Chan et al 652 MNC from making subsequent entries in other markets. Thus, we hypothesize the following: Hypothesis 4a: The founding of subsequent subsidiaries of an MNC has an inverted U-shaped relationship with the number of prior entries of its subsidiaries. Hypothesis 4b: The founding of subsequent subsidiaries of an MNC has an inverted U-shaped relationship with the number of prior exits of its subsidiaries. Method Data source Our data come from annual volumes of Kaigai Shinshutsu Kigyo Soran (‘Directory of Japanese Overseas Affiliates’), which lists the population of overseas subsidiaries that have been established by both listed and non-listed Japanese MNCs. The directories have been used to examine the foreign direct investment (FDI) decisions of Japanese MNCs (e.g., Hennart, 1991; Woodcock et al., 1994; Yamawaki, 1994; Makino and Beamish, 1998; Henisz and Delios, 2001; Lu, 2002; Yiu and Makino, 2002). We used the directories from 1989 to 1998 to create a panel data set of the foreign direct investment of eight large Japanese electronics MNCs: Hitachi, Toshiba, Mitsubishi Electric, NEC, Fujitsu, Sharp, Sony, and Sanyo. These firms compete closely with each other in both the domestic and international markets in a wide range of electronic appliances and equipment. Thus, these firms are well informed about – and are influenced by – the foreign market entry and exit decisions of one another. We chose electronics firms because they have a longer history of international investment, and also have more comprehensive international operations than other industries in Japan. Our observation period takes 1989 as the staring point, because the yen appreciation due to the PLAZA agreement between Japan and the US in September 1985 had sparked off an increased amount of Japanese foreign investment across the world. To create a data set for analysis, we developed a matrix of data in which each record represents one observation per parent firm per host country per industry per year. There are 158,400 records in our sample (eight parent firms 110 host countries 18 global industries 10 years), and our data set shows that 4349 subsidiaries were newly established during the period 1989–1998. We Journal of International Business Studies included the 110 countries that appear in the list of the original database and have publicly available country-level information used in our analysis. We excluded some cases from the original data set because of missing data. The final data set consists of a sample of 156,451 observations. Level of analysis We focus on four levels of analysis: host country, global industry, local industry, and parent firm. The host country is defined according to the country classification that was developed by the United Nations Statistics Division. Regions that are not considered to be legally independent countries but that have relative autonomy over their political and economic activities, such as Hong Kong, are treated as independent host country units. Global industry refers to an industry that spans many host countries, and is defined by a two-digit Standard Industrial Classification (SIC). Local industry refers to an industry that is defined separately in each country, and is again described by a two-digit SIC per host country. Parent firm refers to Japanese MNCs that have their headquarters in Japan, irrespective of whether the major owners of the firm are Japanese or non-Japanese firms or individuals. We focus on eight parent firms, 18 global industries, 110 host countries, and 1980 local industries (18 global industries 110 host countries). Table 1 provides a list of the parent firms, the global industries, and the host countries that are examined in this study. Variables Dependent variable Our dependent variable represents the frequency of foreign market entry, which is measured by the counts of Japanese foreign subsidiaries that were established by each parent firm in each industry in each host country for every year in the period 1989–1998. Independent variables We used the counts of prior entries and prior exits as the two major independent variables in our analyses. Prior entry is measured by the counts of foreign subsidiaries that were established in the preceding year, and prior exit is measured by the counts of foreign subsidiaries that were terminated in the preceding year. Both variables are measured at the following four levels of analysis. Interdependent behavior in foreign direct investment Christine M.

(1) Host country level: prior entries and prior exits made by other firms in the same country in different industries. (2) Global industry level: prior entries and prior exits made by other firms in the same industry in different countries. (3) Local industry level: prior entries and prior exits made by other firms in the same industry in the same host country. (4) Parent firm: prior entries and prior exits made by the same parent firm. Levels 1–3 represent the effects of other firms, and level 4 represents the effects within a firm. The effects at the host country level are measured by the counts of prior entries and prior exits of other firms in each host country. The effects at the global industry level are measured by the counts of prior entries and prior exits of other firms in each global industry. The effects at the local industry level are measured by the counts of prior entries and prior exits of other firms in each local industry. The counts of other firms at the host country and the global industry levels exclude the counts of other firms at the local industry level, and therefore the prior entries and prior exits of other firms in the same host country, global industry, and local industry represent mutually exclusive reference groups. The effects at the parent firm level are measured by the counts of the prior entries and prior exits of each parent firm. To test the hypothesized inverted U-shaped relationships between the variables, we included both linear and quadric terms in the models. We also included the density in the models, which is the number of all Japanese subsidiaries in each cluster at each level at the beginning of each year. The effect of density is not tested in the analysis, but needs to be controlled because it represents the carrying capacity at each level of the population, which has been found to influence both the founding and disbanding rate in a population (Hannan and Freeman, 1989).4 To make our analysis consistent with prior organizational Journal of International Business Studies Interdependent behavior in foreign direct investment Christine M. Chan et al 654 ecology research, we included both the linear and quadric terms of density at each of the four levels of analysis in the models. Control variables We included two parent firm-level control variables in the analyses. First, we controlled for parent firm size. Parent firm size represents either the size of the available pool of resources or capabilities that can be exploited for entry into a new market (Penrose, 1959; Hymer, 1976), or the organizational inertia that constrains new changes (Aldrich, 1979; Hannan and Freeman, 1989). Some studies have found evidence of a positive impact of firm size on foreign direct investment (Caves and Mehra, 1986; Terpstra and Yu, 1988), whereas other studies have found that firm size is not necessarily a barrier to internationalization (Coviello and McAuley, 1999; Lu and Beamish, 2001). We included this variable to control for the possible upward effects of parent firm size on foreign market entry. Second, we controlled for the research and development (R&D) intensity of the parent firm, which is measured by R&D expenses divided by total sales. Previous studies have treated R&D intensity as a proxy for the technological advantages of a firm (Caves, 1996), which constitutes a part of the firm’s ownership advantages that drive foreign direct investment (Dunning, 1988). A positive association has been found between the degree of R&D intensity of an investing firm and the likelihood that the firm will engage in foreign direct investment (Hennart and Park, 1994). Recent studies also suggest that foreign firms with advanced technological capabilities often use foreign direct investment as a means to enhance or source locally available technology (Chang, 1995; Florida, 1997; Kuemmerle, 1999). Thus, we included this variable to control for the possible upward effects of the technological advantages of the parent firm on foreign market entry. We also included two host country specific control variables – political hazard risk and GDP per capita – in our analysis. Political hazard risk is derived from the political hazard index that was developed by Henisz (2000a, b), which measures the feasibility of policy change in a country. Research has suggested that foreign firms face more uncertainties in host countries in which the political hazard risks are high. Such uncertainties are expected to increase the perceived political and expropriation risks in a host country, which discourages inward foreign investment. We, there- Journal of International Business Studies fore, included this variable to control for the possible downward effects of political hazard risks on foreign market entry. A high value for this variable indicates a low risk of political hazard in a host country. GDP per capita represents the income level of the economy in a host country. Traditional foreign direct investment theory suggests that foreign firms are more likely to engage in marketseeking foreign direct investment in host countries in which the income level – and hence the consumption power – is relatively high, and are more likely to engage in labor-seeking foreign direct investment in host countries in which the income level, and hence the labor cost, is relatively low. We included these variables to control for the possible country-specific effects of the income level of economies on foreign market entry. We also controlled for year effects on new entries during the observation period. A correlation matrix of all of the variables is provided in Table 2. Model estimation As our dependent variable is derived from count data and has zero counts in some clusters in host countries and industries (both global and local) in the observation period, we employed a zeroinflated negative binomial model (ZINB) to test our hypotheses. As our sample consists of longitudinal panel data on Japanese foreign subsidiaries that are clustered by host country, global industry, local industry, and parent firm, our analyses need to address two potential sources of bias: lack of independence and unobserved heterogeneity (Allison, 1995, 1999). Lack of independence arises because our sample contains repeated observations across years, and unobserved heterogeneity arises because our models cannot control for all of the remaining host country, global industry, local industry, and parent-firm-specific effects that influence foreign market entry. Both problems lead to autocorrelation among the observations within and between the levels of analysis, and hence to the underestimation of the true standard errors, which inflates the significance tests that are associated with the parameter estimates. To address these problems, we employ a randomeffects model of zero-inflated ZINB and report the robust standard errors that are derived from the robust variance estimator (White, 1980). The robust variance estimator produces consistent standard errors irrespective of the correctness of the correlation structure that is assumed by the regression model. Using the robust standard errors allows us to Interdependent behavior in foreign direct investment Table 2 Descriptive statistics and correlations Mean Std Min 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 4.00 115.0 0.08* 7.00 0.07* 0.69* 27.00 0.05* 0.57* 306.0 0.48* 0.07* 0.06* 0.03* 0.04* 38.00 0.06* 0.04* 0.01* 0.02* 0.78* 22.00 0.06* 0.05* 0.01* 0.02* 0.83* 0.77* 46.00 0.21* 0.24* 0.18* 0.14* 0.32* 0.25* 0.27* 10.00 0.16* 0.18* 0.22* 0.11* 0.15* 0.17* 0.15* 0.54* 7.00 0.12* 0.11* 0.09* 0.09* 0.16* 0.14* 0.16* 0.42* 0.35* 89.00 0.00 0.02* 0.03* 0.02* 0.03* 0.05* 0.03* 0.01* 0.01* 0.01 31.00 0.00 0.01* 0.03* 0.03* 0.02* 0.06* 0.05* 0.01 0.01* 0.01* 0.47* 16.00 0.00 0.01* 0.03* 0.02* 0.01* 0.06* 0.03* 0.01 0.01* 0.01 0.32* 0.42* 13.31 0.01 0.04* 0.03* 0.03* 0.01* 0.00 0.00 0.02* 0.01* 0.00* 0.07* 0.07* 0.11* 4.31 0.01* 0.10* 0.06* 0.07* 0.02* 0.02* 0.01* 0.03* 0.02* 0.01* 0.31* 0.14* 0.16* Christine M.

Chan et al 656 relax the assumption that observations across years are independent, and thus helps us to obtain better estimates of the parameters. Specifically, we estimated the following equation, which fits into the zero-inflated ZINB model5 as Entryit ¼b0 þb1 Entryt1 þ b2 ðEntryt1 Þ2 þ b3 Exitt1 þb4 ðExitt1 Þ2 þb5 Densityt1 þ b6 ðDensityt1 Þ2 þ b7 Zt1 þmi þ nit ð1Þ where Entryit represents the counts of foreign market entries that are calculated for the ith combination in the matrix that consists of 18 global industries, 1980 local industries, 110 host countries, and 8 parent firms in year t. Entryt–1 represents the counts of entries and Exitt1 the counts of exits in year t1 in each cluster at each of the four levels of analysis. The variable Densityt1 represents the density, or the counts of all of the existing (Japanese) subsidiaries in each cluster, at each level of analysis at the beginning of year t1. The term Z denotes the vector of the control variables. The error term mi denotes the unobserved effect in the ith combination, and vit denotes the remainder disturbance. Results As a result of the strong correlations between the independent variables across the levels, we conducted separate analyses for each of the four levels of analysis. The first four models in Table 3 estimate the effects of prior entry and prior exit at the host country (Model 1), global industry (Model 2), local industry (Model 3), and parent firm levels (Model 4), respectively. The last model includes the effects of prior entry and prior exit at all of the levels (Model 5). The results that are provided in Models 1 and 5 show that the linear terms of both prior entry and prior exit at the host country level have a positive and significant impact on foreign market entry, and that the quadric terms of both prior entry and prior exit have a negative and significant impact. The inflection points of prior entry (9.9) and prior exit (3.2) are both within the range of observation. These results indicate that both prior entry and prior exit have an inverted U-shaped effect on new foreign market entry in the subsequent year, which supports Hypotheses 1a and 1b. The results that are provided in Model 2 show that, consistent with our hypothesis, the linear terms of both prior entry and prior exit at the global industry level have a positive and significant impact and the quadric terms of both prior entry Journal of International Business Studies and prior exit a negative impact on foreign market entry. However, the impact of the quadric term of prior entry is not statistically significant. When the density variables at all of the levels are removed from the analysis, both prior entry and prior exit at the global industry level have a significant inverted U-shaped relationship with new foreign market entry (see Model 5). The inflection points of prior entry (15.2) and prior exit (5.9) are within the range of observation, which indicates that the density effect obscures the effect of prior entry on new foreign market entry. In sum, Hypothesis 2a is moderately supported, and Hypothesis 2b is fully supported. The results that are provided in Models 3 and 5 show that the linear terms of prior entry and prior exit at the local industry level have a significant and positive impact, and the quadric terms of prior entry and prior exit a significant and negative impact, on foreign market entry in the subsequent year. The inflection points of both prior entry (5.3) and prior exit (2.8) are within the range of observation, which suggests that both prior entry and prior exit have an inverted U-shaped relationship with new foreign market entry in the subsequent year. To test Hypotheses 3a and 3b, which predict that the effects of prior entry and prior exit on new foreign market entry at the local industry level are stronger than the effects at the host country and global industry levels, we examine the relative effects of prior entry and prior exit at the local industry, host country, and global industry levels by comparing the maximum value of multipliers, inflection points, and the ratio of the maximum value of multipliers over the inflection points across these levels (see Table 4). The ratio provides an indication of the extent to which foreign market entry is elastic to prior entry and prior exit: the higher the ratio, the more elastic the market entry to prior entry and prior exit. Table 4 indicates that as the number of prior entries increases from 0 to 9.9 in a host country, 0 to 15.2 in a global industry, and 0 to 5.3 in a local industry, the ratio of elasticity increases by 1.0 times, 0.2 times, and 1.7 times, respectively. These results show that the number of market entries at the local industry level increases more quickly than that at the host country and global industry levels, as the multiplier reaches its maximum value (9.0) when the number of prior entries is 5.3. Similarly, Table 4 indicates that as the number of prior exits increases from 0 to 3.2 in a host country, 0 to 5.9 in a global industry, and 0 to 2.8 in a local industry, Table 3 Results of zero-inflated negative binomial analyses Variables Level Sign Host Host Host Host Host Host country country country country country country Global Global Global Global Global Global Density Density Density Entryt1 Entryt1 Entryt1 Exitt1 Exitt1 Exitt1 Local Local Local Local Local Local Density Density density Entryt1 Entryt1 entryt1 Exitt1 Exitt1 exitt1 Parent Parent Parent Parent Parent Parent Wald w2 industry industry industry industry industry industry firm firm firm firm firm firm Parent firm Parent firm Host country Host country 4.970**** (0.246) 3.219**** (0.771) 0.075**** (0.012) 0.001**** (0.000) 0.381**** (0.039) 0.019**** (0.003) 0.192** (0.085) 0.038* (0.021) H3a+ H3a H3b+ H3b H4a+ H4a H4b+ H4b 1000.24 5.874**** (0.314) 0.101*** (0.033) 0.003**** (0.001) 0.281**** (0.045) 0.023**** (0.005) 0.444**** (0.023) 0.010**** (0.001) 0.509**** (0.103) 0.020** (0.010) 0.465*** (0.168) 0.112*** (0.041) 0.016 (0.016) 0.148** (0.074) 0.454 (0.387) 0.024**** (0.003) 0.016 (0.016) Model 5 0.466**** (0.056) 0.023**** (0.004) 0.368** (0.157) 0.056* (0.033) 0.032**** (0.009) 0.000**** (0.000) 0.081* (0.046) 0.001 (0.001) 0.191* (0.113) 0.008* (0.006) H2a+ H2a H2b+ H2b + + + + Model 4 0.025 (0.016) 0.247**** (0.062) 0.916**** (0.251) 0.057**** (0.004) 0.061** (0.031) 739.27 0.000 (0.018) 0.146** (0.063) 0.402 (0.370) 0.024**** (0.006) 0.029 (0.022) 2742.97 0.828**** (0.145) 0.078**** (0.018) 0.794**** (0.241) 0.141*** (0.053) 0.070*** (0.025) 0.001** (0.000) 0.011 (0.031) 0.002* (0.001) 0.041 (0.057) 0.009* (0.005) 0.024 0.002 0.015 0.003 0.033** (0.014) 0.261**** (0.067) 0.895*** (0.341) 0.061**** (0.005) 0.124**** (0.039) 0.008 (0.019) 0.166*** (0.063) 0.702** (0.291) 0.028**** (0.005) 0.012 (0.022) 190.35 (0.031) (0.001) (0.066) (0.006) 1971.48 N¼156,451; ****Po0.001; ***Po0.01; **Po0.05; *Po0.10. a The coefficient value of all of the independent variables is divided by 1,000.

These results suggest that the number of market entries at the local industry level increases more quickly than the number of entries at the host country and global industry levels, as the multiplier reaches its maximum value (3.1) when the number of prior exits is 2.8. Our evidence thus implies that MNCs are more sensitive to the prior entry and prior exit of other MNCs in a specific local industry than they are to the same behavior in a global industry or host country. Figure 2 presents graphic illustrations of the relative effects of prior entry and prior exit between the three levels. The figure clearly shows that the effects of both prior entry and prior exit at the local industry level are far more elastic over the range of observed counts of prior entry and prior exit than the same effects at the host country and global industry levels. This evidence provides strong support for Hypotheses 3a and 3b. Model 4 provides the results of the effects of prior entry and prior exit at the parent firm level. Contrary to our hypothesis, the results show that the linear term of prior entry has a negative and non-significant impact, and the quadric term of the prior entry a positive and marginally significant impact, on foreign market entry. The results also show that the linear term of prior exit is positive and the quadric term of prior exit is negative, yet only the latter has a significant impact on foreign market entry. Model 5 shows that neither the linear nor the quadric terms of prior entry and prior exit is statistically significant. These results suggest that an MNC’s prior entry has only a marginal impact Journal of International Business Studies 12 10 Multiplier of founding of subsequent entries Levels of analysis Multiplier and inflection point Multiplier of founding of subsequent entries Table 4 0 5 10 15 20 25 Prior exits Figure 2 Relative effects of prior entry and exit: between-level comparison: (a) effects of prior entries made by other firms; (b) effects of prior exits made by other firms. on its subsequent market entry, which provides limited support for Hypotheses 4a and 4b.6 We also compare the relative effects of prior entry with those of prior exit on subsequent market entry across levels. The graphic comparison of the multipliers of the foreign market entries within each level of observation is presented in Figure 3, which shows that the effects of prior entry are greater than those of prior exit both at the host country and the local industry levels. Figure 3a illustrates that the effect of prior entry at the host country level increases the multiplier to 10.2, whereas that of prior exit increases the multiplier to 1.8. Similarly, Figure 3c shows that the effect of prior entry at the local industry level increases the multiplier to 9, whereas that of prior exit increases the multiplier to 3.1. However, the deviation in the relative impact of prior entry from that of prior exit is smaller at the local industry than at the host country level. At the global industry level, the effects of both prior entry and prior exit increase the multiplier to 2.3 (see Figure 3b). However, the effect of prior exit is more elastic than that of prior entry, as the multiplier reaches its maximum value when the number of prior exits is 5.9 and when the number of prior entries is 15.2.

With regard to the impact of the control variables, the results show that the density of foreign subsidiaries has an inverted U-shaped relationship with subsequent foreign market entry at all of the levels of observation, and that MNCs are likely to engage in foreign direct investment when they are smaller in size and invest in countries with a high income level, or invest in less advanced countries with a greater political hazard risk. Although R&D intensity is found to have a positive impact on subsequent market entry, Discussion One of the key motivations of this study is to empirically examine interdependent foreign market entry behavior at the institutional environment levels of host country, global industry, local industry, and parent firm. Unlike most previous studies that view the foreign market entry decisions of MNCs as a series of independent choices that are influenced mainly by economic factors, the longitudinal analyses of our study show that MNCs make normatively rational choices by following the previous investment behavior of other MNCs. Specifically, our findings indicate that the foreign market entry of an MNC has a strong inverted Ushaped relationship with the prior entry of other MNCs in a host country, global industry, or local industry. This evidence suggests that the establishment of an increasing number of foreign subsidiaries by MNCs in a focal market enhances the legitimacy of this form of market entry, which provides a signal of the attractiveness of the market that triggers other MNCs to engage in mimetic behavior. However, further entries into the market beyond a certain level gives out a signal of intense market competition, and therefore reduces the likelihood that MNCs will imitate each other’s market entry decisions. Our study also provides evidence of the influence of the prior exit decisions of other MNCs on the market entry decisions of an MNC. As with the effects of prior entry, our findings clearly show that the foreign market entry decisions of an MNC have a strong inverted U-shaped relationship with the prior exit of other MNCs from a host country, global industry, and local industry. As the exit of other MNCs releases the finite resources that are required for local operations (for example, pooled skilled labor and access to infrastructure and distribution networks) and frees up the customer base that was previously tapped by the exiting firms, the extent of competition for finite resources and customers decreases, which thereby encourages MNCs to establish foreign subsidiaries in the market. However, further exits from the market give out a signal of a hostile market, which thus discourages MNCs from establishing foreign subsidiaries there. Our study clearly indicates that MNCs do not place an equal emphasis on the actions of other MNCs in a host country, global industry, or local Journal of International Business Studies Interdependent behavior in foreign direct investment Christine M. Chan et al 660 industry. MNCs are more sensitive to – and are more likely to imitate – the decisions of other firms in a specific industry in a host country (local industry) than the decisions of firms in more broadly defined segments (host country and global industry). These findings provide additional evidence for the theory of global and local mimetism (Garcia-Pont and Nohria, 2002), which suggests that the reference group to which firms match their actions is more likely to be a narrowly defined business segment (strategic group) that is composed of firms that possess similar competence bases, use similar resources, and serve similar groups of customers than a broadly defined segment (industry) that consists of multiple but separate business segments. Our evidence advances the literature on external and internal institutional environments (Rosenzweig and Singh, 1991; Westney, 1993). Previous studies have shown that choice of organizational structures and practices is subject to either host country or parent firm isomorphic pulls (Rosenzweig and Singh, 1991; Westney, 1993; Kostova and Zaheer, 1999; Davis et al., 2000). However, our study shows that the source of external influence comes not only from the host country level of the institutional environment, but also from the global and local industry levels. As the magnitude of external influences varies significantly across different levels of analysis, future studies can contribute to the multi-level research7 by examining which MNCs at each level of the institutional environment have the greatest influence on the subsequent market entry decisions of other MNCs, and when this influence has the greatest impact. Our analysis also indicates that, compared with the impact of the prior entry and exit decisions of other MNCs in a host country, global industry, and local industry, the prior entry and exit decisions of the parent firm have a relatively weak impact on its subsequent foreign market entry decisions. This evidence suggests that the foreign market entry decisions of MNCs are influenced primarily by the interdependence among foreign operations between MNCs, rather than by the interdependence among foreign operations within MNCs. One possible explanation for this interesting finding is that MNCs may face greater uncertainty when entering a foreign market with which they are unfamiliar than when repeating an organizational action with which they are familiar. MNCs have insufficient information on the local requirements imposed by the legitimating actors, and have to compete for finite resources in the external environments, Journal of International Business Studies whereas they define the legitimate choices of action and deploy resources within their internal environments. Facing a high level of uncertainty regarding the external markets, MNCs may be more attentive to the signals from their external institutional environments than to those from their internal institutional environments. Future studies should investigate whether MNCs put more emphasis on the actions of other MNCs in other FDI decisions (for example, the timing of and resource commitment to foreign market entry and the location choice of FDI). Our findings also advance the literature on interorganizational imitation. Although the concept of interorganizational imitation has been gaining popularity in the fields of strategic management (Haunschild and Miner, 1997), sociology (Tolbert and Zucker, 1983), and finance (Scharfstein and Stein, 1990), the application of the concept to research on foreign market entry needs further development. First, although research on interorganizational imitation primarily explains why a previously adopted organizational practice or structure increases its successive adoption, it provides limited insight as to whether a previously abolished organizational practice or structure influences its successive adoption. In the case of foreign market entry, we find that the entry decisions of MNCs are significantly influenced not only by the prior entry decisions of other MNCs, but also by their prior exit decisions. In fact, our analysis of the multipliers of market entry demonstrates that the effect of prior exit is as great as that of prior entry at the global industry level. This evidence clearly shows that the prior exits (or the abolition of foreign operations) of other MNCs cannot be assumed to have a nonexistent or constant impact on the subsequent entry decisions of an MNC. Future studies of interorganizational imitation in foreign market entry should incorporate the effects of both prior entry and prior exit into the theoretical model, and should identify the key contingent factors that facilitate and constrain interdependent behavior in foreign market entry. Second, research into interorganizational imitation implicitly assumes a linear relationship between the previous adoption of a particular organizational practice or structure and its subsequent adoption. Underlying this assumption is the notion that there is little or no limit to the mimicking behavior of a firm. However, there are boundary conditions for institutional explanations, because firms may change their perceptions toward Interdependent behavior in foreign direct investment Christine M. Chan et al 661 what was once considered to be a legitimate organizational practice or structure when their situation changes (Scott, 2001). The simple application of the linear association of interorganizational imitation to the context of international market entry is problematic for two main reasons. First, firms may not engage in mimetic foreign market entry behavior when a large number of new entrants provoke competition for the limited available resources and customers in the market. Second, firms may change their perceptions of legitimate foreign market entry behavior when they have limited resources to allocate to foreign market expansion. Our findings clearly confirm the first reason, and suggest that the prior entry of other firms has an inverted U-shaped relationship – as opposed to a linear relationship – to the subsequent entry of new MNCs. An interesting extension of this study would be to incorporate the theory of first-mover advantage and the theory of internationalization into our proposed model of foreign market entry. The literature of first-mover advantage generally favors the risk-taker’s viewpoint, and suggests that firms that enter a foreign market faster than their rivals tend to perform better than those that enter later than their rivals (Isobe et al., 2000). In contrast, the internationalization theory, which focuses on riskaverse behavior in foreign market entry, suggests that firms initially make foreign direct investments on a small scale, and successively increase their resource commitment to the investment as the psychic distance between their home country and the host country is lessened through experience (Johanson and Vahlne, 1977). Our study, however, implicitly assumes that MNCs are risk neutral and respond to legitimating and competitive pressures in a relatively similar fashion. To better understand the foreign market entry behavior of MNCs, future studies could relax the risk-neutral assumption by allowing heterogeneity among the attitudes of firms toward uncertainty, and investigate which MNCs are more (or less) likely to follow their own prior foreign market entry decisions and which are more likely to follow the decisions of other MNCs. Our study has two limitations that suggest some intriguing avenues for future theoretical refinement. First, the extent of the generalizability of the findings of this study is an area of concern. By drawing a sample from Japanese electronics MNCs, this study finds that the decisions of these firms regarding foreign market entry are influenced by the previous investment decisions of other Japanese MNCs. A reasonable question arises as to whether these market-entry decisions are specific to Japanese electronics MNCs, especially as patterns in international diversification differ across countries and industries and the level of global integration of Japanese MNCs is higher than that of their counterparts from other countries. These concerns provide an opportunity for future research to choose other organizational populations of MNCs, and to examine whether the findings can be generalized beyond the context of Japan and the electronics industry. Another potential limitation of the study lies in the validity of the choice of the levels of analysis. In this study, we focused on the host country, global industry, local industry, and parent firm levels of analysis. However, the different regions within a host country, the business groups within an industry, and the alliances and networks between parent firms may also serve as appropriate levels of analysis for the study of the dynamics of foreign market entry. Although we believe that our study contributes to the examination of foreign market entry at multiple levels of analysis, we have not made a detailed examination of other possible levels. To precisely answer the question of which firms should be followed in terms of market entry decisions, future studies should explore the levels of analysis that matter the most.

Notes 1 For example, Cargill Inc., which is a private agricultural company, faced legitimacy problems when entering the Indian market (Kostova and Zaheer, Journal of International Business Studies Interdependent behavior in foreign direct investment Christine M. Chan et al 662 1999). Cargill encountered substantial resistance from local farmers, producers, politicians, and environmentalists because its establishment was perceived to have destroyed the traditional way of life and threatened the country’s economic freedom. 2 The density dependence model proposes that, at low levels of organizational density (or number of firms) of a population, a growth in density enhances the legitimacy of the organizational form, and therefore increases the founding rate. When the density of the population is high relative to the carrying capacity of the environment for organizational form, a growth in density increases the intensity of competition, and therefore depresses the founding rate. 3 DiMaggio and Powell (1983: 143) propose a closely related concept of ‘organizational field’, which refers to ‘those organizations that, in the aggregate, constitute a recognized area of institutional life: key suppliers, resource and product consumers, regulatory agencies, and other organizations that produce similar services or products’. 4 As density represents the number of firms in a population, its value varies depending on the definition of the population boundary. Martin et al. (1998: 571) argue that ‘firms offering similar products that expand from a given home country represent a distinct organizational population in the host location. The population exists as a distinct set because firms develop organizational forms influenced by routines that are specific to the location where their domestic development occurred.’ We follow their argument and define density as the number of Japanese subsidiaries in each cluster at each level of observation. 5 The ZINB model first determines whether a case has an outcome of zero with the probability of 1, then models the nonzero outcomes. Long and Freese (2003) provide detailed descriptions of the model and the analytical procedure. 6 We conducted a sensitivity analysis by dividing our sample parent firms into two groups according to firm size (total sales). We performed the same regression analysis for each group (Model 5) and found consistent results. 7 Recent studies have emphasized the multi-level analysis of organizational phenomena in the context of MNCs (e.g., Hawawini et al., 2004; Makino et al., 2004; Ricart et al., 2004).
