Department of Management of Organizations, Hong Kong University of Science and Technology, Clear Water Bay, Hong Kong 2 We argue that compositional gaps in international joint venture (IJV) management groups, along parent company lines, will accentuate distinct managerial coalitions. Such gaps can occur on dimensions of observable demography, less apparent demography, or psychological characteristics. While compositional gaps in IJV management groups can provide the basis for healthy substantive conflict, such gaps—particularly if they are large—also tend to induce relationship conflict and heighten substantive conflict beyond its beneficial range. This can set off a downward spiral of relationship conflict, substantive conflict, and behavioral disintegration in the group. These harmful group processes further interact reciprocally with any tensions that might exist between the IJV parents, engendering a second downward spiral. Our model has implications for the performance of international joint ventures, and it serves as a foundation for designing interventions to avoid the downward spirals we portray. Copyright 2001 John Wiley & Sons, Ltd. Major corporations are relying more than ever on joint ventures for executing their international strategies. A mounting trend since the 1970s, the use of joint ventures allows companies to rapidly and economically complement their own resources with those of other firms. As one prominent observer put it, the rapid proliferation of joint ventures represents an “explosion of cooperation” (Harrigan, 1988). In an international context, such alliances can facilitate quick entry to new geographic markets, access to specialized or lowwage labor, meshing of complementary technologies, learning from partners, and other advantages of cross-border combinations (e.g., Barkema et al., 1997; Contractor and Lorange, 1988; Hamel, 1991; Inkpen and Beamish, 1997; Li and Shenkar, 1996). Or so the logic goes. For, although some joint ventures achieve their parents’ objectives, success Key words: management groups; joint ventures; international organization *Correspondence to: Donald C.

Indeed, there is consistent evidence that international joint ventures (IJVs) have high failure rates (Chowdhurry, 1992; Harrigan, 1988; Hennart, Kim and Zeng, 1998; Park and Ungson, 1997; Schaan, 1988; Yan, 1998). For example, several empirical studies have shown instability rates of close to 50% for IJVs (e.g., Bleeke and Ernst, 1991; Kogut, 1988, 1989). Other studies question whether joint ventures add benefits to partners (Kent, 1991). Numerous vantages have been taken to explain differing degrees of success of international joint ventures (see Yan, 1998; Yan and Zeng, 1999; for reviews). For instance, research has informed our understanding of differentials in IJV performance by examining partners’ strategic complementarities (Hill and Hellriegel, 1994; Saxton, 1997), partners’ relative size and bargaining power (e.g., Harrigan, 1988; Park and Ungson, 1997; Yan and Gray, 1994), partners’ experience with joint ventures (Barkema, et al., 1997), joint venture control mechanisms (Geringer and Hebert, 1989; Yan and Gray, 1994), and trust between partners (Sheppard Received 15 june 1999 Final revision received 1 February 2001 1034 D. C. Hambrick et al. and Tuchinsky, 1996; Walsh, Wang, and Xin, 1999). Some research has contributed to our understanding of the relationships between conflict and performance in IJVs and other partnerships. For instance, Ding (1997) found that conflict significantly hindered joint venture performance. In contrast, Yan and Gray (2001) did not find a significant relationship between perceived conflict between joint venture partners and firm performance. Mohr and Spekman (1994) found the “joint problem solving conflict resolution technique” to be associated with positive firm performance. And Hebert (1996) observed a positive relationship between trust between IJV partners and performance, especially in partnerships where one partner held a dominant position. Missing in all prior research on international joint ventures, however, has been any attention to the composition and functioning of the management groups placed in charge of the ventures. Yet, from an abundance of theory and empirical research (summarized in Hambrick, 1994; Jackson, 1992), there is considerable evidence that management group composition and behaviors are of great consequence to organizational outcomes. For instance, management group composition has been shown to affect organizational innovation (Bantel and Jackson, 1989), strategic persistence (Finkelstein and Hambrick, 1990), competitive moves and countermoves (Hambrick, Cho, and Chen, 1996), and performance (Eisenhardt and Schoonhoven, 1990). The few studies that have examined management group processes reveal, as expected, that senior group composition affects information processing, power and influence patterns, and other elements of intra-group dynamics, which in turn affect strategic choices and performance (e.g., O’Reilly, Snyder, and Boothe, 1993; Smith et al., 1994). Management group composition is expected to have particularly great implications for international joint venture outcomes, because joint venture managers not only bring their individual experiences and biases to the group, but also typically represent their respective parents in an inherently conflict-laden exchange relationship (Newman, 1995). Moreover, in IJVs the managers are almost always of differing nationalities—often (but not necessarily) the nationalities of the parent firms’ headquarters. And, because of systemic differences in the social and economic institutions Copyright 2001 John Wiley & Sons, Ltd. of their home countries, as well as differences in the career patterns and cultures of their respective parent firms, the managers may also differ on other demographic dimensions, such as age and education, and also on psychological dimensions, such as values and beliefs, further accentuating the gaps between the managerial subgroups. As a result, in IJVs, there are likely to be schismatic, factionalized perceptions and behaviors among top managers, with accompanying implications for business effectiveness. In this paper, we provide a complementary, not competing, perspective to the literature on IJVs by exploring the implications of the composition of an international joint venture management group (IJVMG) for the group’s functioning and the IJV’s performance. We integrate a set of ideas from the literature on top management teams, small group behavior, organizational demography, crosscultural behavior, and joint ventures. We start with a descriptive section on the concept of an international joint venture management group. We then develop a model of how IJVMG compositional gaps, which occur along parent company lines, influence group functioning and IJV effectiveness. We argue that compositional gaps in the IJVMG provide different skills and perspectives that may lead to healthy substantive (or task) conflict. However, such compositional gaps also tend to reduce identification with the whole team and lead to relationship (or emotional) conflict. Relationship conflict, in turn, may heighten substantive conflict beyond its beneficial range. This can set off a downward spiral of relationship conflict, substantive conflict, and behavioral disintegration in the group. These harmful group processes further interact reciprocally with any tensions that might exist between the IJV parents. That is, IJVMG conflict is both aggravated by and aggravates parent tensions—a second downward spiral. Although our paper deals specifically with IJVMGs, our central ideas and model are potentially applicable in any group setting in which members are expressly assigned as delegates from larger social entities (e.g., merger integration teams). INTERNATIONAL JOINT VENTURE MANAGEMENT GROUPS: CONCEPTS AND AN EXAMPLE Very little research has examined managerial staffing and behaviors in international joint ventures. Strat. Mgmt. J., 22: 1033–1053 (2001) International Joint Venture Management Groups The few existing works have focused primarily on the general manager position. For instance, Schaan and Beamish (1988) described the distinctive roles and challenges of general managers of IJVs in lesser-developed countries, and Shenkar and Zeira (1992) studied the antecedents of role conflict and role ambiguity for IJV general managers. Our focus, instead, is on the top management group responsible for the joint venture. Although little attention has been paid to such groups (Pearce, 1997, is an exception), it may be within these social units that many issues of trust and conflict are manifested—phenomena which have been the subject of considerable discussion by joint venture researchers (Koenig and Van Wijk, 1992; Ring and Van de Ven, 1992). Moreover, the broader literature on managerial effects consistently indicates that management group characteristics (including composition and processes) explain much more variance in organizational outcomes (e.g., strategies and performance) than do characteristics of the individual top executive alone (summarized in Finkelstein and Hambrick, 1996). We anticipate that IJV top management groups may have extraordinary effects on the success and failure of international joint ventures. Properties of international joint venture management groups We define the joint venture management group as the relatively small group of highest-ranking managers of the IJV. This group typically includes the general manager, deputy general manager (if such a position exists), and other managers who report directly to these two positions (typically heads of functional areas). This definition is in keeping with how most researchers of top management groups define such entities, and it is in line with how CEOs tend to define their top groups (Hambrick, 1995). For IJVs, the top management group generally consists of five to ten individuals. Control of management positions is a central issue in IJV negotiations, and joint venture partners consistently seek to have “due representation” in the management of the IJV (Koot, 1988; Lewis, 1990, Lorange and Roos, 1991). The general manager position is seen as most crucial. If a partner has a dominant equity position or some other basis of power (such as critical technology), it can usually secure this top position (Child and Yan, 1999). Copyright 2001 John Wiley & Sons, Ltd. 1035 The parent who does not win the general manager position will argue strongly for other slots, sometimes even proposing the creation of special positions (such as deputy general manager or director of administration) as a way of obtaining the desired level of representation in the management of the IJV. There is a tendency for functional areas to be headed by managers from whichever parent has a comparative advantage in that domain. However, even these demarcations are not clear-cut. For example, we have seen Chinese partners who insist on heading up manufacturing that involves proprietary Western technology (as part of their own learning efforts), and American partners who negotiate to head up marketing of consumer products in China. In order to warrant distinct analytic treatment, IJVMGs must have special properties that render the literatures on top management teams and small groups incomplete. In our view, the primary special property of significance is that many IJVMGs are inherently coalitional, as joint venture managers also serve as “representatives” or “delegates” of their respective parents. On the one hand, the managers are expected to focus on the IJV’s success. But, as an outgrowth of the inherent strains in having two (or more) owners who may have conflicting agendas, the JV managers are also expected to protect their own parent’s interests and ensure that their counterparts do not try to abuse those interests (Child, Yan, and Lu, 1997; Mjoen and Tallman, 1997; Schaan, 1988; Yan and Gray, 1994). This group condition, in which representative coalitions are highly salient, may commonly occur in other contexts—for example, in mergers, when two subunits are combined, or when a new CEO arrives from the outside with several lieutenants—allowing our model to be applicable beyond the joint venture setting. Not all IJVMGs, however, have the coalitional properties we describe. At a minimum, a group would need to have representatives expressly drawn from the two parents. Killing’s (1983) typology of joint venture control structures, as extended by Geringer and Hebert (1989), helps us anticipate when this would be the case and, hence, helps frame the scope of our primary interest. Two types of joint ventures generally would not have managerial representatives drawn from the two parents. The first is the “dominant parent” JV, in which the venture is managed entirely by one of the parents, with the other parent playing Strat. Mgmt. J., 22: 1033–1053 (2001) 1036 D. C. Hambrick et al. a more passive role (often supplying only capital). The second type of JV falling outside our scope is the “independent” JV, in which the JV general manager is given considerable autonomy, including in managerial hiring; in many such cases, most or all of the JV’s senior managers are hired externally, with no particular ties to the parents, and hence, little potential to form coalitions along parent company lines. The two remaining types comprise our analytic scope. The “shared control” JV is one in which both parents exercise a high degree of influence over the venture’s full range of decisions; in such a case, the parents tend to place their own delegates into as many managerial positions as they can reasonably secure; and the parents are interested in, and feel dependent upon, the managers in the positions filled by the other parent (Child and Yan, 1999). The second type that lies within our scope is the “split control” JV (introduced by Geringer and Hebert, 1989). In this instance, both parents are involved in the management of the JV, but they agree to control distinct functional areas. In this case, the IJVMG would consist largely of managers drawn from the two parents, but the two coalitions may structure their tasks so as to have little interdependence with each other, and hence relatively little occasion to interact. To a great degree, the IJVMG might actually approximate two sub-groups, working in parallel, while referring any conflicts to the JV general manager for resolution. It can be expected, however, that the two subgroups will have some dealings with each other. It is evident that shared control and split control JVs differ in the degree of interdependence and interaction between the management coalitions. Any coalitional dynamics will be more intense in the more interdependent shared control setting than in the more parallel-functioning split control setting. We will incorporate this contrast into the model and propositions we develop, particularly arguing that there is greater potential for coalitional conflict in shared control IJVs. Although the evidence on the performance tendencies of different JV control types is mixed (see Geringer and Hebert, 1989; Yan and Gray, 1994; Yan and Zeng, 1999; for reviews), to the extent that JVs involving managers drawn from both parents encounter difficulties, it may be precisely because of the coalitional properties of the management groups and the Copyright 2001 John Wiley & Sons, Ltd. processes that are triggered (Killing, 1983; Mohr and Spekman, 1994; Ding, 1997). Two brief elaborations are useful for further establishing the context of our argument. First, the coalitional or representational nature of IJVMGs is likely to be most pronounced at the early stage of the IJV and may diminish over time. At the outset, the partners are especially unsure of each other, have no successes to reassure them, and tend to appoint their own trusted managers to represent them in running the new venture—often putting a premium on the perceived loyalty of the managers they designate. Over time, if the IJV lives beyond its perilous first few years and achieves some successes, the managerial staffing of the IJV can change a great deal. It becomes more likely that the IJV general manager will not be a career employee of one of the parents (having risen through the IJV itself or having been hired externally); and the GM will be granted more leeway for hiring other key managers, including from the outside. Thus, with time and success, the IJV takes on the characteristics of the “independent control” JV (Killing, 1983), and the IJVMG becomes less coalitional and more like other top management groups. However, since only a minority of IJVs survive beyond a few years (Kogut, 1989; Park and Ungson, 1997), our conception of coalitional IJVMGs is widely apt. A second clarification is that, as legal entities, IJVs have boards of directors that provide additional oversight, particularly over strategic issues, such as use of any JV profits, reinvestment policy, and setting strategic priorities (Child and Yan, 1999; Yan and Gray, 1994, 1996). The boards typically consist primarily of representatives of the partners, in proportion to their equity and nonequity contributions to the ventures (Child and Yan, 1999). These boards are an important control mechanism, and their composition and processes (so far, largely unstudied) are potentially interesting in their own right. Indeed, the group processes we will model may occur similarly at the level of the IJV board. In order to maintain our analytic focus, however, we explicitly consider the IJV management group, where operational issues (such as sales and distribution policy, pricing, and production planning) are resolved (Child and Yan, 1999). Such operational matters have been found to be of major significance to JV performance (Yan, 1993; Hebert, 1996; Yan, 1997). Eventual Strat. Mgmt. J., 22: 1033–1053 (2001) International Joint Venture Management Groups extension of our model to IJV boards would seem reasonable, even promising. The role of boards still may bear on the IJVMG processes we will discuss. In particular, we will theorize about the effects of relationships between the IJVMG and their parents; boards may be an unspecified, but major, conduit by which these relationships occur. Therefore, we will revisit IJV boards briefly when we examine hypotheses relating to parent tensions. An example To simplify our conceptual analysis, we focus on IJVs with two parents.1 In order to provide a frame of reference, an illustration of an IJVMG is useful. Although no standard group profile exists, the one we will discuss has many characteristics in common with other IJVMGs we have observed. The (disguised, but actual) IJV is Pharmex-Tianjin, a newly created alliance between Pharmex, a large U.S.—based pharmaceutical company, and the government of Tianjin, China. The purpose of the IJV was to produce anti-inflammatory drugs, a specialty of Pharmex, at a greenfield plant in Tianjin, and to market the drugs throughout China. Pharmex viewed the IJV as a way to increase their global scope, in a rapidly expanding economy. The Tianjin government was interested in creating new outlets for their raw chemical production and in learning about Western technology. Executives in the two companies agreed at the outset that the equity holdings would be 50-50. However, the remaining negotiations were protracted (over three years) and tense. Debated issues included the plant location, number of employees, benefits for employees, and Chinese access to Pharmex technology. The deal almost unraveled over Pharmex’s resistance to sourcing chemical ingredients solely from a state-owned chemical factory, due to concerns about ingredient purity. The Tianjin officials were proud of their relatively new chemical plant and were offended by Pharmex’s concerns. Nevertheless, they agreed to allow a Pharmex technician to serve in a passive quality assurance capacity at the chemical plant for the first two years of the IJV. Negotiations about initial managerial staffing were also contentious. The Chinese partner argued 1 In some cases, IJVs have more than two parents (sometimes including relatively passive minority partners). Extension of our ideas to such cases could be considered in future research. Copyright 2001 John Wiley & Sons, Ltd. 1037 that the general manager should be from its ranks, because of complex external relations that must be managed in the Chinese environment, because all but a few employees would be Chinese, and because the product was going to be sold in China. Pharmex felt strongly that the GM must be one of theirs, asserting that their proprietary product formulation and extensive pharmaceutical manufacturing expertise were the most critical and complex resources for the success of the venture. Pharmex prevailed, and it was agreed that the GM would be nominated by Pharmex, with Tianjin holding veto power. Tianjin then insisted that a deputy GM position be held by one of its managers, responsible primarily for external and government relations. The remaining management positions were similarly contested. The Chinese partner insisted on assigning a Director of Personnel and a Controller. Pharmex itself wanted control of accounting, because it did not trust Tianjin’s financial expertise; Pharmex succeeded in negotiating for a Director of Finance who, like the (Chinese) Controller, would report directly to the GM and who would somewhat duplicate the Controller counterpart. The Director of Manufacturing and the Director of Marketing were designated to be from Pharmex. Thus, the IJV is of the “shared control” type (Killing, 1983). Figure 1 shows Pharmex-Tianjin’s initial management group in the form of an organization chart and also gives brief biographical data on each manager. What should be clear from the example is that: 1) the negotiations that precede IJV managerial appointments create an important part of the context in which the management group will operate; sometimes considerable tension lingers between the partners, which is transmitted to the assigned managers; 2) the partners tend to strive mightily to have due representation on the top team; and, accordingly; 3) IJV managers, especially at the outset of a venture, are thrust into roles not only as managers, but as delegates of their respective parents.

Figure 1. Management group of Pharmex-Tianjin group makeup. One approach has been to examine the average compositional characteristics of the group, on the premise that the average reflects the prevailing orientation of the group—a bias that will be manifested in the group’s choices (e.g., Finkelstein and Hambrick, 1990; Bantel and Jackson, 1989). A second focus has been on the heterogeneity, or dispersion, of compositional characteristics of all members of the group. Here, the logic has been that diverse backgrounds can provide either an informational endowment or act as an impediment to effective group processes (Jackson, 1992). In the case of joint ventures, a third conception of management group composition is Copyright 2001 John Wiley & Sons, Ltd. required—one that is based upon the inherently coalitional nature of the group, which occurs because the managers are delegates from their parents. The existence of coalitions in a group generally causes members to be competitive, turfconscious, and rigid (Eisenhardt and Bourgeois, 1988; Mannix, 1993). In addition, the existence of coalitions sets up a demarcation, or “faultline” (Lau and Murnighan, 1998), which deepens and widens as a function of the other differences between the coalitions. As Lau and Murnighan pointed out, group faultlines—particularly along demographic lines—can go unnoticed without the presence of external forces. What Lau and Murnighan did not consider, Strat. Mgmt. J., 22: 1033–1053 (2001) International Joint Venture Management Groups however, is that an external factor can itself be the primary basis for a faultline. An important version of this occurs, we believe, when members of a group are expressly appointed as delegates or representatives from another entity, as in an IJVMG. An example used by Lau and Murnighan helps convey the distinction we are drawing. Consider a four-person group that consists of two individuals (A and B) who share several demographic characteristics and two other individuals (C and D) who share several different characteristics. Among Murnighan and Lau’s examples, this is a case of a very strong faultline. But, what if A and C are one unit’s designated representatives to the group and B and D are representatives from another group? The faultlines are essentially erased (or at least dramatically altered), as each coalition is now demographically identical, with very different implications for group processes (Marcus-Newhall et al., 1993). For example, if there are Chinese in each group, conflict between the two groups might be ameliorated. Note that other variations can occur—as when a seemingly diverse group, when considered along a coalitional axis, might reveal notable demographic schisms. If these schisms are then coupled with social or political pressure from each coalition’s respective constituency, the resulting group processes can be much more extreme than would be predicted by looking only at the demographic faultlines or other more conventional indices of group composition. A large number of possibilities exist, indicating the importance of noting possible areas where faultlines may hint at possible downward spirals, and where complementarities or similarities might help minimize downward trends. In the next section, we propose that the “compositional gap” between the managerial coalitions of an IJVMG will have a substantial effect on group functioning and IJV performance. Our model, however, may be applicable for explaining the dynamics in any of an array of groups in which the members are representatives from other social entities, including, for instance, merger integration teams and contract negotiation teams. Concept of the compositional gap A compositional gap, in the context of an IJVMG, is the difference between the managerial coalitions on one or more compositional dimensions Copyright 2001 John Wiley & Sons, Ltd. 1039 of potential importance to the group’s functioning. Such differences could be in readily observable demographic characteristics (such as nationality, age, language), in less visible demographic attributes (such as education, functional background, company tenure), or in psychological attributes (such as values, beliefs, cognitions) (Jackson, May, and Whitney, 1995; Markoczy, 1997; Milliken and Martins, 1996; Tsui, Egan, and O’Reilly, 1992; Wiersema and Bird, 1993). Differences on any one dimension do not necessarily mean there will be differences on other dimensions, nor will our line of argument presume such. In actuality, however, gaps on one dimension often may occur along with gaps on other dimensions—particularly in the context of IJVMGs—because the coalitions are drawn from distinctly different managerial populations, which are embedded in systematically different institutional arrangements. At a broad level, different national cultures tend to have fundamentally different sets of social institutions—including education systems, labor markets, and geographic mobility—which tend to lead to wholesale differences in managers appointed to IJVs from those countries (Calori et al., 1997; Whitley, 1992). At a narrower level, each parent firm will have its own internal culture, including management selection and staffing practices, yielding a distinctly skewed set of managers who are eligible for IJV assignments. As a result, the pervasive differences that exist in national institutions and parent companies create the likelihood of differences on multiple dimensions in the IJVMG. In the Pharmex-Tianjin example, the two coalitions differed substantially in their ages (a mean difference of ten years), their amount of formal education (mean difference of five years), and their tenures with their parent companies (difference of 12 years). Seventy-five percent of the Pharmex coalition had primarily line experience (marketing, manufacturing, and sales), while the Tianjin managers all had primarily staff experience (accounting, external relations, and human resources). We have no data on the psychological attributes of the managers, but the two coalitions probably differed substantially in their values and cognitions, as well. An eventually elaborated model of IJVMG compositional gaps may integrally consider various kinds of gaps. Here, we consider gaps at two levels. First is the overall “aggregate gap” between Strat. Mgmt. J., 22: 1033–1053 (2001) 1040 D. C. Hambrick et al. the two coalitions on all dimensions thought to be relevant. If n dimensions are being considered, the aggregate gap might be roughly thought of as the summed Euclidean distance between the two groups of managers in n-dimensional space, akin to calculations for cluster analysis. Figure 2 shows several possible profiles, based (for simplicity) on only two compositional dimensions. In Figure 2a, the aggregate gap is large, in Figure 2b it is moderate, and in 2c and 2d the gaps are essentially non-existent. The second way we consider gaps is according to more specific classes of compositional characteristics—a) readily observable demographics (e.g., race, nationality, gender), b) less observable demographics (e.g., education, functional background), and c) psychological characteristics (e.g., values, personality, cognitive style). Here again, the gap would be calculated as the multidimensional distance between the two coalitions on all relevant and/or available dimensions within one of these classes. As we shall discuss, prior research has found that these different forms of diversity may have differing effects on group processes. Implications of compositional differences As summarized by Williams and O’Reilly (1998), a substantial stream of research has identified three major mechanisms by which compositional differences can affect group processes. First, and perhaps most examined of the three, is social categorization. In an effort to define their identities and protect their self-esteem, individuals classify themselves and others into social categories (Tajfel and Turner, 1986). Categorization can be on the basis of overt characteristics, such as nationality, age, race; or, after behaviors have been revealed and observed, classification can occur on more psychological dimensions, such as personality (extroverts vs. introverts), values (individualists vs. collectivists), or cognitive style (intuitives vs. analytics). Research has consistently found that when categorizing occurs, even on trivial criteria, b: Moderate Gap Dimension Y B B B Dimension Y a: Large Gap A A A Dimension X B A A B A Dimension X A B B A Dimensions X Figure 2. d: No Gap Dimension Y Dimension Y c: No Gap B A B A B B A A B Dimension X Illustrative compositional gaps (each IJVMG consists of managers from Parent A and Parent B, arrayed on two compositional dimensions) Copyright 2001 John Wiley & Sons, Ltd. Strat. Mgmt. J., 22: 1033–1053 (2001) International Joint Venture Management Groups members perceive the outgroup as less trustworthy, capable, and cooperative than members of their own ingroup (Brewer, 1979; Tajfel, 1982). This categorization affects how groups interact. In his essay outlining the embedded intergroup relations perspective, Alderfer (1986) indicates that the basic idea here has a long history. When the seeds of ingroup–outgroup categorization take root, there is a: “. . .view of things in which one’s own group is the center of everything, and all others are scaled and rated with reference to it . . .Each group nourishes its own pride and vanity, boasts itself superior, exalts its own divinities, and looks with contempt on outsiders”. (Sumner, quoted in Alderfer, 1986: 191) These words were from a work originally published in 1906, helping Alderfer make the point that the concept of social categorization is not new. A second implication of group composition, related to social categorization, is the welldocumented tendency for people to like, trust, and interact with others who are similar to them (e.g., Berscheid and Walster, 1978; Tsui and O’Reilly, 1989). The similarity/attraction paradigm has been validated on group attributes ranging from demographic to psychological (summarized in Williams and O’Reilly, 1998). Third, a group’s composition has direct implications for the information and knowledge that is available within the group (Tsui and Gutek, 1999). Demographic characteristics, such as nationality, education, and functional experiences, tend to confer members with certain information. Additionally, psychological characteristics, such as values and personality, affect how members interpret information (e.g., Gruenfeld et al., 1996). Diverse groups thus have a broader base of information, knowledge, insights, and skills at their disposal than do homogeneous groups. Such breadth has both advantages and drawbacks for the group’s processes, to which we now turn. COMPOSITIONAL GAPS, COGNITIVE DIVERSITY, AND SUBSTANTIVE CONFLICT The strategic logic of joint ventures lies in the complementarities of the partners, with each Copyright 2001 John Wiley & Sons, Ltd. 1041 supposedly bringing something different of value to the venture. So, too, do managerial groups comprised of widely differing characteristics bring a diverse stock of knowledge and skills to the JV (Hoffman, 1959; Hoffman and Maier, 1961; Milliken and Martins, 1996). For example, IJVMGs consisting of widely different nationalities have greater cognitive diversity—the variety of cognitive resources available within a group—than groups consisting all of one nationality or of highly similar nationalities. This cognitive diversity stems from the influence that nationality has on one’s knowledge, values, cognitive schema, and language (Roberts and Boyacigiller, 1984; Laurent, 1991; summarized in Hambrick et al., 1998). Similarly, differences on other dimensions also confer more diverse cognitive capabilities than would exist in more homogeneous groups. Managerial coalitions that vary in their ages, functional backgrounds, and education bring diverse informational insights to the joint venture management situation (Jackson, 1992; Triandis, Hall, and Ewen, 1965; Watson, Kumar and Michaelson, 1993). Although there may be a general tendency for the magnitude of a compositional gap to be associated with the cognitive diversity of a group, this is not always the case, at least not enough to allow a cogent proposition. For example, a small compositional gap could exist either because a) the two coalitions are each very homogeneous but similar in their profiles (as in Figure 2c), thus conferring little cognitive diversity or b) the two coalitions are each very heterogeneous, but similarly so (as in Figure 2d), thus conferring substantial cognitive diversity. Cognitive diversity can be considered a resource for effective management of joint ventures, as divergent points of view and knowledge bases are brought to bear on problem solving (Jackson, 1992). Bantel and Jackson (1989:109), for instance, argued that “when solving complex, nonroutine problems, groups are more effective when composed of individuals having a variety of skills, knowledge, abilities, and perspectives.” It is particularly valuable if the compositional gaps in the IJVMG correspond with the “requisite variety” of the business situation (Ashby, 1956). For instance, in the case of Pharmex-Tianjin, the venture benefits from having Liu’s understanding of the Tianjin government, Peng’s experience with Chinese Strat. Mgmt. J., 22: 1033–1053 (2001) 1042 D. C. Hambrick et al. workers, Estevan’s knowledge of Western pharmaceutical production technology, and so on. This IJV, by its nature, calls for diverse resources in the management group. The compositional gaps that accompany these cognitive complementarities, however, often will lead to conflict. Indeed, an abundant stream of research indicates that group diversity engenders conflict (summarized in Milliken and Martins, 1996; Pelled, 1996). Although there is a substantial body of literature on inter-group relations and conflict (see Alderfer, 1986, for a comprehensive review), recent theorists have concluded the importance of distinguishing between two types of conflict: substantive conflict and relationship conflict. Substantive conflict—sometimes called “task conflict” (e.g., Pelled and Adler, 1994) or “cognitive conflict” (Amason and Schweiger, 1994) is intellectual opposition among participants (Guetzkow and Gyr, 1954: 380), regarding the group’s agenda, priorities, choices, and so on. Relationship conflict—sometimes called “emotional conflict” (Jehn, 1994) or “affective conflict” (Pelled, 1996)—involves interpersonal incompatibilities, typically including mistrust, animosity, and annoyance (Jehn, 1995). These two forms of conflict have different effects on group outcomes (Jehn, 1995; Pelled, 1996) and therefore warrant separate discussions. Accordingly, in this section we address substantive conflict; below we address relationship conflict, as well as the interaction between the two types. Large compositional gaps can be expected to give rise to substantive conflict. When the managerial coalitions are of widely differing nationalities, for instance, they bring divergent experiences and frames of reference to problem solving, which they each take to be valid and supported by their own prior successes (e.g., Markus and Kitayama, 1991; Trompenaars, 1993). Beyond the tendency for people of different nationalities to differ in their interpretation and processing of information, is their additional tendency to have fundamentally different preferences for how the group should operate (Heller and Wilpert, 1979; Hofstede, 1991).2 As a direct result of differing values and experiences, managers 2 We leave outside our analysis any tendencies for national cultures to differ in whether and how they express conflict. For instance, it has been observed that overt expression of conflict is generally frowned upon in collectivist cultures (Tinsley, 1997). Consideration of cultural tendencies of the specific nationalities Copyright 2001 John Wiley & Sons, Ltd. may stridently disagree on matters encompassing supervisory policies, risk-taking, control systems, urgency, and others (e.g., Perlmutter and Hennan, 1986). Other demographic and psychological gaps also will create substantive conflict (Hoffman and Maier, 1961; Milliken and Martins, 1996; Strauss, 1964). Managerial coalitions that differ widely in their ages, education, values, and cognitions diverge in the “givens” they bring to an administrative situation (March and Simon, 1958), including their knowledge of alternatives and their knowledge or estimates of consequences attached to alternatives (Hambrick and Mason, 1984; Pelled, 1996). These differences will emerge as substantive conflict in the group’s functioning: Proposition 1: The greater the IJVMG aggregate compositional gap—in terms of readily observable demographic characteristics, less observable demographic characteristics, and psychological characteristics—the greater the substantive conflict between the coalitions. Although we have argued that all forms of diversity tend to give rise to substantive conflict, some research has found that visible demographic factors (such as race and gender) do not have as much effect on task conflict as do those factors that are more informationally- or professionallyladen (such as functional background or education) (e.g., Pelled, 1996; Pelled, Eisenhardt and Xin, 1999; Jehn, Chadwick and Thatcher, 1997). These authors did not formally consider psychological factors. But an extension of their argument would place psychological characteristics (such as cognitive style) in the domain of substantive factors that can greatly affect members’ points of view on task matters, in contrast to visible demographic factors which may have more incidental effect. Thus: Proposition 1a: Compositional gaps on observable demographic dimensions will be less strongly related to substantive conflict than will gaps on less observable demographic dimensions or on psychological dimensions. The effect of IJVMG compositional gaps on conflict can be expected to differ depending on the nature of the JV control structure. As discussed represented in joint ventures could be an interesting future extension of our model. Strat. Mgmt. J., 22: 1033–1053 (2001) International Joint Venture Management Groups earlier, group dynamics will be more intense in the more interdependent “shared control” setting (as typified by our Pharmex-Tianjin example) than in the more parallel-functioning “split control” setting. Therefore: Proposition 1b: The positive association between the magnitude of IJVMG compositional gaps and substantive conflict will be greater for shared control IJVs than for split control IJVs. There is considerable evidence that, up to a point, substantive conflict enhances effectiveness for groups performing non-routine tasks (although it may be harmful to group effectiveness when the task is highly routine) (Jehn, 1995). Substantive conflict causes facts and perceptions to be put under scrutiny and subjected to extensive debate (Jehn, 1994); it helps in minimizing “groupthink,” or an excessive striving for unanimity (Janis and Mann, 1977); and it injects a healthy tension and ferment into group processes, which allow better and more creative choices to emerge (Jackson, 1992). Studies generally have found a positive relationship between substantive conflict and group effectiveness (e.g., Amason, 1996; Jehn, 1994; Nemeth, 1986; Torrance, 1957). However, extremely great degrees of substantive conflict can be expected to cause breakdowns in information processing and decision-making (Gersick, 1989). If the gulf is very wide, the group will have no middle ground, no ready ability to translate each other’s perceptions or preferences, and particularly a difficulty in matters of execution (Jehn, 1995). Rather, it is with a moderate compositional gap (such as shown in Figure 2b) that IJVMGs are expected to perform best. Such groups experience constructive substantive conflict, possess complementary information and capabilities, and are compositionally close enough (maybe even having some overlapping or shared characteristics) that they can understand and interpret each other’s perspective. Thus, we propose: Proposition 2: There will be a curvilinear (inverted-U) relationship between substantive conflict and IJV performance, with moderate levels of substantive conflict most positively associated with IJV performance. The discussion so far suggests that IJVMG compositional gaps provide complementary capabilities and also engender substantive conflict, which, Copyright 2001 John Wiley & Sons, Ltd. 1043 if held to a moderate level, enhances IJV effectiveness. If we could stop here, the prognosis for many IJVs would be favorable, and their success rates would be greater than they are in fact. Unfortunately, however, IJVMG compositional gaps have additional negative effects, including the tendency to propel substantive conflict beyond its constructive range. COMPOSITIONAL GAPS AND IJVMG PROCESSES: DOWNWARD SPIRAL #1 Compositional gaps and relationship conflict Compositional differences generate not only substantive conflict, but also relationship conflict—or interpersonal disaffection (Milliken and Martins, 1996; Jackson, 1992). This well-known tendency is a direct outgrowth of the fundamental human tendency for people to be drawn to, like, trust, and communicate with others like themselves, and to avoid, distrust, and dislike those who are dissimilar (e.g., Byrne, 1971; Tsui and O’Reilly, 1989). Differences in readily-apparent personal characteristics (e.g., gender, race, age) have been found to particularly give rise to mistrust and dislike in group settings, as a result of stereotyping (Pelled, 1996; Jackson, 1992). However, even differences in less visible traits (e.g., functional background and values) can stir relationship conflict, as group members personalize the differences in their professional paradigms and priorities (Pelled and Adler, 1994). As telling evidence that even sub-rosa differences can give rise to relationship conflict, Jehn (1994)—in a study of 88 student groups—found that consensus (or homogeneity) of values (personal traits with no readily apparent outward signs) was more negatively related to relationship (“emotional”) conflict (r = −0.26; p < 0.001), than to substantive (“task”) conflict (r = −0.16; p < 0.01). Nationality differences are among the gaps that have been found to affect relationship conflict (e.g., summarized in Adler, 1986; Bochner and Hesketh, 1994; Verkuyten, de Jong and Masson, 1993). In the case of nationality, the accompanying traits that cause disaffection range from the readily apparent (e.g., language and demeanor) to the underlying (cognitive schema and values) (summarized in Hambrick et al., 1998). Language barriers are well known for directly causing mistrust Strat. Mgmt. J., 22: 1033–1053 (2001) 1044 D. C. Hambrick et al. and miscommunication, and also making it difficult to surmount mistrust that stems from other sources. Also, seemingly minor behaviors—such as eye contact, body language, speech rhythms, and punctuality—vary systematically by nationality, further causing interpersonal unease and mistrust (LaFrance and Mayo, 1978; Mesquita and Frijda, 1992). Differences in cognitive schemas and values, due to cultural distance, similarly cause mistrust (e.g., Pelled, 1996). In joint ventures, the likelihood of compositional gaps engendering relationship conflict is particularly great, because of the coalitional nature of the management groups and the accompanying tendency for in-group/out-group social categorization to occur (Alderfer, 1970, 1986; Tajfel, 1982; Taylor, Sheatsley and Greeley, 1978), as well as for members to identify with their in-group rather than with the full group (Tajfel and Turner, 1986). These cognitive processes gives rise to ingroup/out-group hostility, or seeing the in-group as worthy and efficacious, and seeing the out-group as uniformly unworthy and inept (Tajfel, 1982). If the two coalitions differ not only in nationality but also on other demographic and psychological dimensions (such as in the Pharmex-Tianjin example, and as we expect to often be the case), social categorization will be further accentuated and intergroup polarization will be even more pronounced (Brewer and Kramer, 1985). Thus: Proposition 3: The greater the IJVMG aggregate compositional gap, the greater the relationship conflict between the coalitions. In line with some previous research (Pelled, 1996; Jehn et al., 1997; Jehn, Northcraft and Neale, 1999), it can be expected that gaps on observable demographic dimensions (e.g., nationality, age, gender) have particularly pronounced influences on stereotyping, categorization processes, and, in turn, on relationship conflict. Therefore: Proposition 3a: Compositional gaps on observable demographic dimensions will be more strongly related to relationship conflict than will gaps on less observable demographic dimensions or on psychological dimensions. Again, we expect the implications for group processes to be greater in shared control IJVs than in split control IJVs: Copyright 2001 John Wiley & Sons, Ltd. Proposition 3b: The positive association between the size of IJVMG compositional gaps and relationship conflict will be greater for shared control IJVs than for split control IJVs. Essentially all available evidence indicates that relationship conflict harms group performance (Jehn, 1997, 1999). We expect the same in the context of IJVMGs: Proposition 4: The greater the relationship conflict between managerial coalitions, the lower the IJV’s performance. Reciprocal escalation of substantive and relationship conflict Although substantive and relationship conflict are conceptually distinct, they have been found to interact reciprocally, often propelling each other (Pelled and Adler, 1994). Disagreements which start on substantive grounds can become personalized and emotional (e.g., Pelled and Adler, 1994; Hambrick, 1995). And, even more likely, relationship conflict will heighten the likelihood that substantive conflict will emerge and accelerate. If there is antipathy within the group, members will tend to take strong stands—opposing their adversaries—on issues that otherwise might have been of little interest to them, and a polarization occurs. Essentially all studies that have empirically examined the two types of conflict have found a positive, significant association between them (Amason, 1996; Guetzkow and Gyr, 1954; Jehn, 1994). In a review of eleven prior studies, Simons and Peterson (in press) report an average correlation of 0.47 between the two types of conflict. Compositional gaps in an IJVMG give rise to stereotyping and mistrust, which will accentuate the reciprocal conversion of substantive conflict into relationship conflict and vice versa. Particularly when there are multiple stark cues that the out-group is different, even someone who is generally open-minded and tolerant of diversity will tend to succumb to stereotyping (Lau and Murnighan, 1998). In the Pharmex-Tianjin case—where the coalitions differ widely in their nationalities, ages, education, functional experiences, and possibly also values and beliefs—we can envision a generally open-minded manager thinking (or even speaking) in terms of “old Communist bureaucrats” or “immature and insensitive Strat. Mgmt. J., 22: 1033–1053 (2001) International Joint Venture Management Groups American cowboys.” This stereotyping, and the behaviors it prompts, cause substantive disagreements to become more emotional. Further, members take the other coalition’s substantive stances as rooted in that group’s inferiority rather than in its legitimate viewpoint. Thus, beyond its respective effects on substantive and relationship conflict, a large compositional gap can cause an iterative cycling between the two: Proposition 5: The greater the IJVMG aggregate compositional gap, the greater the reciprocal escalation of substantive and relationship conflict between the coalitions. Since stereotyping and categorization are particularly pronounced as a result of differences in observable demographic characteristics, we propose the following: Proposition 5a: Compositional gaps on observable demographic dimensions will be more strongly related to the reciprocal escalation of substantive and relationship conflict than will gaps on less observable demographic dimensions or on psychological dimensions. The relationship is also moderated by the IJV’s control structure: Proposition 5b: The positive association between the size of IJVMG compositional gaps and reciprocal escalation of substantive and relationship conflict will be greater for shared control IJVs than for split control IJVs. 1045 is related to, but distinct from “social integration,” which places more emphasis on members’ sense of “group pride” or “team spirit” (Seashore, 1977; Shaw, 1981; Smith et al., 1994). The obverse of behavioral integration, disintegration, can be expected to be an integral part of the IJVMG downward spiral that is triggered by compositional gaps.3 An absence of substantive conflict will be accompanied by behavioral disintegration, from a simple lack of interaction; moderate amounts of substantive conflict will enhance integration, as information is exchanged and vigorously processed; but extremely great amounts of substantive conflict will cause behavioral disintegration, as managers tire of constant argument and attempt to insulate their own activities from those of others. Relationship conflict will interact reciprocally with behavioral disintegration in an escalating direction: In-group/out-group antipathy will cause the coalitions to try to avoid each other and compartmentalize their tasks to minimize interaction. The reduced interaction gives the coalitions less chance to adjust their categorizations, stereotypes and mistrust of each other (Cook, 1978). In the context of an IJVMG with wide compositional gaps, this spiral of substantive conflict, relationship conflict, and behavioral disintegration is very likely to occur and will be quick to accelerate. Thus: Proposition 6: The relationship between IJVMG substantive conflict and behavioral disintegration is curvilinear—behavioral disintegration is greatest for very low and very high levels of substantive conflict. Conflict and behavioral disintegration Conflict can be thought of as opposing valences—either substantive or emotional—within a group. However, conflict does not in itself describe behavioral interactions. In a recent attempt to identify and assess the tendency for some top management groups to have more “teamlike” properties than others, Hambrick (1994) set forth the concept of “behavioral integration.” Defined as “the degree to which mutual and collective interaction exists within the group,” behavioral integration has three main elements for management groups: information exchange, collaborative behavior, and joint decision-making. In emphasizing substantive interaction, behavioral integration Copyright 2001 John Wiley & Sons, Ltd. Proposition 7: The greater the relationship conflict in an IJVMG, the greater the behavioral disintegration—due to 2-way causality. Proposition 8: Under conditions of large aggregate compositional gaps, an IJVMG will tend to spiral: substantive conflict, relationship conflict, behavioral disintegration, more conflict, and so on. 3 We reverse Hambrick’s term, calling it “disintegration,” to simplify the wording of propositions and accompanying discussion. We use the label to convey the direct inverse of behavioral integration. Strat. Mgmt. J., 22: 1033–1053 (2001) 1046 D. C. Hambrick et al. We expect Propositions 6, 7 and 8 to hold for both shared control and split control IJVs, although the dynamics can be expected to differ. In shared control IJVs, where the coalitions’ tasks are highly interdependent, a given compositional gap will tend to engender relatively intense conflict (as laid out in Propositions 1b, 3b and 5b), which in turn will drive the coalitions apart behaviorally and cycle back to cause even more mistrust, doubt, and conflict. In split control IJVs, where the coalitions’ tasks are not as interdependent, it takes a larger compositional gap to create intense conflict (again as in Propositions 1b, 3b and 5b); but once that conflict occurs, the behavioral schism will widen, lessening the chances for improved understanding and trust, and the cycle will continue. Thus, the tipping point for the downward spiral is lower in shared control than in split control IJVs; but once the respective tipping point is reached, the spiral ensues in each case. Our portrayal of one type of deficiency leading to even greater deficiencies is consistent with the thinking of prior theorists who have portrayed organizational decline as a “downward spiral” (e.g., Bozeman and Slusher, 1979; Ford, 1980; Forrester, 1971; Hambrick and D’Aveni, 1988; Staw, Sandelands and Dutton, 1981). There is consensus in the literature that organizational decline produces dysfunctional consequences at both individual and organizational levels (e.g., Staw et al., 1981; Whetten, 1980, 1987). The literature has generally shown that as conflict, secrecy, rigidity, centralization, formalization, scapegoating, and conservatism increase, morale, innovativeness, participation, leader influence, and longterm planning decrease (e.g., Cameron, Kim and Whetten, 1987; Cameron, Whetten and Kim, 1987; D’Aveni, 1989; Weitzel and Jonsson, 1989; Whetten, 1980, 1987). As discussed by Thietart and Forgues (1995:20), “When the system is driven by positive feedbacks, which reinforce the original change made in one of its variables, small changes are accumulating exponentially to lead to an explosive situation.” Interestingly, there has been relatively little attention to downward spirals in group processes. In an IJVMG, such spirals can be very pronounced and difficult to stop. Minor mis-steps, small perceived breaches of trust, and business setbacks all fuel coalitional stereotyping, conflict and disintegration. The two coalitions are alert to evidences of each others’ shortcomings; when they observe Copyright 2001 John Wiley & Sons, Ltd. any such signs, their outgroup categorizations and conflict are magnified; the spiral is under way. Of course, faltering performance is not only fuel for the spiral; it is also a consequence, to which we now turn. Downward spiral and IJV performance IJV management groups that experience this spiral will generate unfavorable results for their ventures. Such groups will fail to exchange information, fail to collaborate, create schisms within the ventures, and engage in erratic decision making. Prior studies consistently reports harmful performance effects stemming from relationship conflict (summarized in Jehn, 1997). Research has similarly suggested that behavioral disintegration in management groups is deleterious to organizational effectiveness (Eisenhardt and Bourgeois, 1988; Hambrick, 1994). IJVMGs, like most other management groups, must orchestrate numerous interdependencies. These include conversion of marketing programs and sales forecasts into production plans, allocation of resources across activities and regions, setting polices and making judgements about equitable treatment of employees in different functions and locales, and (in tandem with the IJV’s board) setting overall business direction. Namely, the tasks of IJVMG members are not very separable or independent. If an IJVMG—which is coalitional to start with—experiences extreme conflict and behavioral disintegration, these interdependencies will be mismanaged and the venture will suffer. Proposition 9: The greater the combined levels of substantive conflict, relationship conflict, and behavioral disintegration, the worse the IJV’s effectiveness (in terms of survival and meeting parents’ objectives). In the case of Pharmex-Tianjin, our example, such problems were severe. The two coalitions experienced extreme mistrust and conflict; they sharply reduced their interactions; and decisionmaking became rigid and mechanical. A particularly grave problem occurred when the Pharmexappointed managers were energetically planning for geographic sales expansion and increased production capacity, while the Tianjin-appointed managers claimed that no further expansion could Strat. Mgmt. J., 22: 1033–1053 (2001) International Joint Venture Management Groups occur—or even be discussed—until certain employee housing benefits were improved. During this impasse, several scheduled management meetings were cancelled, and each group of managers conveyed their frustrations, not to each other, but to their higher-ups in their respective parents. These latter actions, then, fueled a second downward spiral, to which we now turn. IJVMG PROCESSES AND TENSIONS BETWEEN PARENTS: DOWNWARD SPIRAL #2 No management group exists in a vacuum, and international joint venture management groups especially function in an interorganizational web. In the case of an IJV, managers take cues and direction from their respective parent firms (Shenkar and Zeira, 1992); they submit information and impressions to their parents as well. These twoway flows create the conduits for a second downward spiral in IJVs. As noted earlier, a central focus in prior literature on international joint ventures is on the tensions and mistrust that can exist between the parents. Some of this focus has been on what might be called the “inherent tensions” between the partners, as determined by such factors as their strategic non-complementarities (Killing, 1983; Li and Shenkar, 1996; Pearce, 1997), their potential for opportunism (Hennart, 1991; Parkhe, 1993), and the dissimilarities of their national cultures (Child, Markoczy, and Cheung, 1994; Park and Ungson, 1997). An additional focus, however, has been on the “emergent tensions” between the partners, as manifested (and aggravated) by acrimonious negotiations (Adler, Brahm, and Graham, 1992; Mann, 1989), insistence on stringent checks and controls to guard against each other’s misor malfeasance (Mjoen and Tallman, 1997; Yan and Gray, 1994), and jostling for bargaining power (Harrigan and Newman, 1990). For purposes of our model, the initial sources of parent tensions are exogenous and outside our scope. Our interest, instead, is in the degree to which such tensions exist and how they interact with IJVMG processes. When considerable tensions between the parents exist, the parents will convey these tensions—wittingly or unwittingly—to their representative managers in the IJV. Each set of managers will be influenced to be wary and skeptical about the Copyright 2001 John Wiley & Sons, Ltd. 1047 motives, abilities, and behaviors of the other parent and its managers. Such attitudes, in turn, will emerge in the functioning of the IJVMG. Imagine a situation in which tensions between parents are great. Minor differences in the priorities expressed by the two sets of managers (substantive conflict), or even minor personality clashes (relationship conflict), will be taken as validation of the parent’s concern about the other group’s unworthiness, and the downward spiral within the IJVMG itself will be reinforced (See Mann, 1989, for such a case). Unfortunately, however, the dynamic also goes the other way: to the extent that the IJVMG is factionalized and conflict-laden, the more negative will be the reports of the managers back to their respective parents. The managers will communicate upward their distrust of each other, tending to interpret the problems within the group as evidence of systemic problems with the joint venture and the partner. The parents, in turn, will become more skeptical of each other and of their continuing association. Proposition 10: The more pronounced the downward spiral within the IJVMG (that is, the greater the combination of substantive conflict, relationship conflict, and behavioral disintegration), the greater the tensions between the IJV parents—due to 2-way causality. The venture’s board of directors might often be the conduit by which tensions, distrust, and skepticism are communicated (Gray and Yan, 1997; Yan, 1993). In addition, the board itself might be susceptible to the coalitional dynamics we have portrayed, amounting in essence to a third downward spiral. We omit this possibility from our formal scope but note it as a potentially important outgrowth of the organizationally-nested nature of joint ventures. In sum, compositional gaps within joint venture management groups are, at one level, a predictable outgrowth of the underlying logic for engaging in joint ventures in the first place: strategic complementarities. And, within bounds, compositional gaps can yield benefits of cognitive diversity and healthy substantive conflict. However, these bounds are often exceeded, with compositional gaps giving rise to a downward spiral of substantive conflict, relationship conflict, and behavioral disintegration. These processes within Strat. Mgmt. J., 22: 1033–1053 (2001) 1048 D. C. Hambrick et al. the IJVMG interact with tensions between the parents, to create a second downward spiral. These dynamics (summarized in Figure 3), so far overlooked in the literature on joint ventures, may account in great part for the poor record of international joint ventures. Unfortunately, this was the outcome for Pharmex-Tianjin, the example we have cited throughout. The management group experienced severe friction, which added fuel to lingering tensions between the parents. After 18 months’ operation, the venture was disbanded, and the new plant was sold at a fraction of its cost to another U.S.–Chinese venture. RESEARCH IMPLICATIONS AND FUTURE DIRECTIONS The conceptual model presented here should draw attention to empirical research on the under-studied topic of international joint venture management groups. There are several promising avenues for future research. The first priority is to examine empirically the coalitional nature of joint venture management groups and the key factors affecting the salience and strength of such coalitions. It would be valuable to study the coalitional properties of a sample of IJVMGs and the impact of such coalitions on group processes—for example, stereotyping, social categorization, communication, learning, and joint decision making among top management group members. We posited earlier that the coalitional nature of the IJVMG is most pronounced at the early stages of the IJV and may diminish over time. Therefore, future research should also examine the role of IJV life cycles on the coalitional dynamics in the IJVMG. A second area for future research is related to the concept and measure of compositional gaps. We have defined the compositional gap as differences between the characteristics of one managerial coalition and those of the other coalition within the IJVMG. Further research, however, is needed in refining this concept and developing measures for empirical analysis. For example, rather than just focusing on the aggregate differences between the two coalitions, future studies might attempt to develop compositional gap measures that can encompass the magnitude, Tension Between Parents IJV Control Type Shared Control vs. Split Control + Downward Spiral #2 + + Relationship Conflict Compositional gap* - observable demographics (nationality, age, etc.) − JV Effectiveness + + - achievement of - less apparent demographics (education, functional + backgrounds, etc.) - psychological characteristics (values, beliefs, etc.) + Behavioral Disintegration Downward Spiral #1 −/+ + − parents’ objectives - survival +/− Substantive Conflict + *We do not attempt to show the differing effects of compositional gaps of different types (as conveyed in Propositions P1a, P3a, and P5a). Cognitive Diversity Figure 3. A model of compositional gaps and downward spirals in international joint venture management groups Copyright 2001 John Wiley & Sons, Ltd. Strat. Mgmt. J., 22: 1033–1053 (2001) International Joint Venture Management Groups distinctiveness, and scope of differences between managerial coalitions on key dimensions. The “magnitude” of difference might be gauged by the simple difference in coalitional means. “Distinctness” of difference exists when the coalitions differ and the members of each coalition are relatively homogeneous. When the coalitions are homogenous within themselves, schismatic stances will be particularly likely, with little middle ground, and substantive conflict will be aggravated. Each coalition will see the other as a unitary monolith; stereotypes will be accentuated, and relationship conflict will heighten (Kramer, 1991; MarcusNewhall et al., 1993). Finally, the scope of difference depends on how many managers comprise the coalitions. The greater the number of members of each coalition, the more that each coalition will be self-reaffirming and confident in its own perspective; the less compromise and give-and-take will occur; and the greater the conflict (Brewer and Kramer, 1985). In sum, it may be very helpful to consider multiple elements of compositional gaps and their effects on IJVMG functioning and IJV performance. The downward spirals resulting from compositional gaps and parent tensions are not inevitable in international joint venture management groups. Therefore, a third area for further research is to explore the different types of mechanisms that might successfully prevent the downward spirals. For example, careful attention to group composition may be a first step in addressing the potential negative effects of IJVMG compositional gaps. Future research should examine whether the use of seasoned internationalists, or managers who have relatively short parent company tenures, or even deliberate efforts to minimize the homogeneity of assigned managers, would help minimize the downward spirals and improve IJV chances of success. Other factors, such as establishment of overarching goals for the IJV, creation of a strong identity for the IJVMG, design of shared-fate managerial incentives, and the use of conflict management techniques may also help arrest or minimize the downward spirals. These ideas should be examined in future research. While we have focused our discussions on the top management groups in IJVs, the concept of compositional gaps can also be applied to other organizational contexts in which representational coalitions are salient—for instance, in mergers, when two subunits are combined, or when a Copyright 2001 John Wiley & Sons, Ltd. 1049 new CEO arrives from the outside with several lieutenants. Finally, while our study has focused on the implications of the composition and processes of IJV management groups on the venture’s performance, it is also important to explore the relative contributions of this perspective versus others in the IJV literature as explanations of IJV performance. Therefore, future empirical studies should incorporate both management group composition and process variables, as well as variables previously identified in the IJV literature to shed light on this important issue. CONCLUSIONS International joint ventures are strategically important to today’s corporations, but often fail to meet expectations. In fact, many simply fail. Although scholars have examined an array of factors potentially involved in IJV success or failure, little or no attention has been paid to the composition and functioning of top management groups of joint ventures. We have attempted to fill this void in the literature by presenting an elaborated model of joint venture management group composition and processes. We hope that this paper will draw attention to the under-studied topic of IJV management groups. The downward spirals resulting from compositional gaps between the coalitions within the IJVMG are a potentially important explanation of venture failure. Knowing how the spirals are triggered and accelerate can improve the likelihood of accurately anticipating and diagnosing IJV challenges, as well as guiding appropriate preventive or corrective actions. Moreover, our model may be applicable to an array of situations in which groups consist of distinct coalitions representing larger entities.
