While it is largely undisputed that cross-boarder knowledge flows contribute to the firm’s success, our knowledge on the effects of specific transfer mechanisms is scarce. We examine the impact of different dimensions of distance to test the applicability of personal coordination mechanisms (PCM) and technology-based coordination mechanisms (TCM) in situations of differentiation and dispersion. Data on 324 knowledge transfer relationships of MNC units was used to test our hypotheses. While TCM function relatively context-free, we find that PCM are moderated by distance. Our results support moderating effects of geographic, cultural and linguistic distance, which are vital to our understanding of knowledge transfer effectiveness in MNCs. Keywords: Knowledge Transfer, Multinational Corporation, Geographic Distance, Cultural Distance, Linguistic Distance 2 1. INTRODUCTION During the last years, academics and practitioners have realized that knowledge flows across dispersed organizational units are vital for the companies’ success (Bartlett and Ghoshal, 1989; Hedlund, 1994; Kogut and Zander, 1992). In fact, the ability to leverage its knowledge resources globally has been proclaimed by many scholars as the true raison d’être of the MNC (Kogut and Zander, 1992; 1993; Doz et al., 2001; Asakawa and Lehrer, 2003; Mahnke and Pedersen, 2004; Andersson et al., 2007; Monteiro et al., 2008). In order to build on the organizations’ knowledge stock, functional units of multinational corporations (MNCs) need to share knowledge across organizational entities. They have to be able to transfer this knowledge within organizational networks characterized by separation through time, space, culture and language. And while the advent of modern information technology – which reduces or even eliminates some of the inherent challenges posed by distance such as communication or coordination costs – has led some scholars to declare the “death of distance” (Cairncross, 1997), others have recently reminded us about the persistence of distance in international business (Nachum and Zaheer, 2005; Ghemawat, 2001). In short, our understanding of how distance affects knowledge transfer between MNC units is still scarce. If distance complicates international knowledge transfer: How and under which circumstances does distance affect knowledge transfer effectiveness in the MNC? Given the centrality of knowledge sharing in the MNC, much attention has been granted to the question why and how knowledge transfers occur by focusing on the determinants and obstacles of such flows (e.g. Szulanski, 1996; Simonin, 1999; Gupta and Govindarajan, 2000; Tsai, 2001; Minbaeva et al., 2003). To a much lesser extent, however, progress has been made with respect to the organizational mechanisms or capabilities used by MNCs to transfer the knowledge (Foss and Pedersen, 2002; Martin and Salomon, 2003a; Hansen and Lovas, 2004; Almeida et al., 3 2002). In an attempt to answer the question how different knowledge transfer mechanisms enhance the effectiveness of knowledge transfer, the present paper takes a closer look at two distinct mechanisms: personal coordination mechanisms (PCM) and technology-based coordination mechanisms (TCM). To shed light on this issue we employ a contingency perspective on the value of knowledge transfers for the recipient unit. This perspective emphasizes that the value of obtaining and using knowledge should be assessed by evaluating the benefit of the received knowledge to the recipient unit, rather than by measuring the quantity of knowledge flows. In doing so, our paper follows recent scholarly thinking that it is the benefit, relevance or performance rather than the mere occurrence of knowledge flows that matters (Chini, 2004; Haas and Hansen, 2005; Schulz, 2003; Mahnke et al., 2004). The contingency view implies that important contextual variables are likely to influence to what extent the recipient unit is able to benefit from a knowledge transfer. Given the paramount importance of distance in international business theory and for the conceptualization of the MNC (e.g. Ghoshal and Westney, 1993; Nachum, 2003), we focus on the question how various facets of distance (spatial, cultural and linguistic) influence the effectiveness of transfers via PCM as well as TCM. We utilize this perspective to empirically test a set of hypotheses on original data from 164 MNC units reporting on 324 knowledge flows. The subsidiaries in our sample applied the two sets of transfer mechanisms to transfer knowledge from subunits separated by varying distances. We examined the extent to which a focal subsidiary utilizes both, PCM and TCM to obtain and use valuable knowledge from other subsidiaries in the MNC. 4 The research contributions of this paper are threefold. First, this study adds to literature on knowledge flows in multinational firms by accentuating the role of knowledge transfer mechanisms. Second, it advances theory by grounding the knowledge flow debate in a more robust contingency (context-fit-performance) framework, and demonstrates that the effectiveness of transfer mechanisms and knowledge flows is moderated by important contextual variables. Third, this study responds to calls for a more differentiated investigation of distance (Nachum and Zaheer, 2005; Friedland and Boden, 1994) by investigating the separate effects of geographic, cultural and linguistic distance. As such, it contributes to a much needed and more nuanced understanding of distance. The paper proceeds as follows: It starts with a review of relevant literature to outline the value of knowledge and the role of knowledge transfer mechanisms in the MNC. We proceed by introducing different dimensions of distance before we spell out some testable hypotheses. The third section lays down the methodology and data gathering approach. Following the analysis and presentation of our primary results we deepen our investigation into the interaction effects of different dimensions of distance and knowledge transfer mechanisms in the MNC. Finally, we conclude the paper by pointing out practical implications for managers in multinational firms. 2. THEORETICAL BACKGROUND In line with an increasing body of literature, we conceptualize the MNC as consisting of semiautonomous entities (Bartlett and Ghoshal, 1989; Gupta and Govindarajan, 1991; Hedlund, 1994; Nohria and Ghoshal, 1997, Doz et al., 2001), in which units in dispersed locations take on various missions and control heterogeneous stocks of knowledge (Foss and Pedersen, 2002). We define 5 knowledge as “accumulated practical skill or expertise that allows one to do something smoothly and efficiently” (Kogut and Zander, 1992, p. 386). Organizational knowledge, which is in the focus of this study, embraces different functions of the firm and the whole range of managerial and operational processes with the implication that know-how is generated in all productive activities (Almeida et al., 2002). Applied and researched in a diverse set of disciplines, the notion of knowledge has recently found an increasing interest among strategic and international management scholars. It has been argued that knowledge, like other and more tangible assets, constitutes a prime organizational resource (Grant, 1996). As such, knowledge seems to contribute to, or even determine, the competitive position of the firm. However, the possession of knowledge-based assets does not by itself guarantee that a firm will be able to exploit these assets in foreign operations (Martin and Salomon, 2003b; Hansen and Lovas, 2004). Existing studies on knowledge transfer in MNCs have tended to emphasize the impediments or barriers of knowledge flows without spending much thought on the mechanisms used to facilitate the transfer (for notable exceptions see Martin and Salomon, 2003a; Hansen and Lovas, 2004). As a consequence, the prime concern has been to identify the contingencies under which knowledge flows occur, but not whether the knowledge transfer is effective. Thus, while previous research has enlightened our understanding of the determinants of inter-unit knowledge flows, most scholars implicitly followed a relatively naïve conceptualization of knowledge as an economic good (that has value by mere exchange) as opposed to an information good (that has value in use) (Haas and Hansen, 2005). Recently, a few studies have investigated the effectiveness of knowledge flows (e.g. Monteiro et al., 2008; Ambos et al., 2006; Szulanski and Jensen, 2006; Mahnke et al., 2004; Haas and Hansen, 2005). Those studies suggest that not every transfer is beneficial per se and that relevance, task-unit performance or application of knowledge in a new 6 context will depend on important contingencies. In their study of international consulting firms Hansen et al. (1999) identified two broad categories of transfer mechanisms and contend that successful knowledge management depends on the “fit” or “coalignment” of different knowledge transfer tools and mechanisms with the firm’s overall strategy. While they already introduce the notion of alignment of knowledge transfer mechanisms with certain contingencies, these insights are largely based on anecdotal evidence rather than on formal propositions. Our study builds on this line of thinking and develops a more formal contingency view on knowledge transfer within MNCs. The contingency perspective generally suggests that there is no single best organizational orientation and no universalistic organizational choices which result in optimal outcomes in every situation (Lawrence and Lorsch, 1967; Ginsberg and Venkatraman, 1985). Rather, organizational choices must be matched to the subunit’s external context and this “fit” is the determinant of superior performance. During the last decades, the concept of fit has played a key role for theory building in strategic management, organizational theory and managerial orientation (Zajac et al., 2000; Venkatraman, 1989; Gupta and Govindarajan, 1984). In this paper we adopt a similar position with regards to knowledge flows: the ‘coalignment’ or ‘fit’ between transfer strategy (operationalized as transfer mechanisms used) and the transfer context will result in a higher transfer effectiveness. Hence, the main proposition of this study is that the utilization of one or the other transfer strategy leads to higher benefit (performance) levels only to the extent that there is a fit between the contextual imperatives and the mechanism being deployed. Of prime importance from this perspective, then, is the identification of the critical contingency relationships with respect to knowledge flows. In this study we focus on distance. Understanding how distance affects knowledge transfer effectiveness is critical because transfers 7 across distance come at a cost. MNCs do not only make significant investments in technology but also maintain costly organizational structures and processes to initiate knowledge flows (Bartlett and Ghoshal, 1989; Hedlund, 1994; Grant, 1996). Specifically, we propose that the development of both PCM and TCM will positively impact the effectiveness of knowledge flows. Further, we argue that when distance (cultural, geographic, linguistic) among the focal unit and the sending unit increases, PCM become less effective in transferring knowledge, thus, eventually tipping the scale in favor of TCM capabilities in contexts where large distances have to be bridged. The relationships that we examine are shown in figure 1. In the next section, we develop hypotheses about the nature of these relationships in the context of globally dispersed units of large European MNCs. ************* insert Figure 1 about here ************* 3. DEVELOPMENT OF HYPOTHESES 3.1. Knowledge Transfer Mechanisms To mobilize knowledge firms rely on various transfer mechanisms. In line with recent research (Schulz and Jobe, 2001; Hansen and Haas, 2004; Hansen et al., 1999), we broadly classify these mechanisms in two categories: technology-based coordination mechanisms (TCM) and personal coordination mechanisms (PCM). There has been some debate whether the two modes are substitutes or complements, but there is a general consensus that both are instrumental in transferring knowledge within the MNC. However, as we will argue later on, the two mechanisms build on a contrasting logic, which has important implications for their applicability in the international setting and merits a separate discussion. 8 Technical infrastructure plays a central role in intra-organizational knowledge transfer as it allows employees to codify, store and access knowledge. The main purpose of knowledge management systems is to maximize the exploitation of resources that are embedded within a network of units separated through time and space. Such infrastructure includes tools like business intelligence, collaboration software, distributed learning, knowledge discovery and mapping. Recent empirical evidence and the first pitfalls of knowledge management initiatives in practice have shown that people often reject sophisticated knowledge management systems due to a lack of user knowledge (Leonard-Barton, 1995) or a misalignment with the company’s overall strategy (Hansen et al., 1999). But selected studies have provided empirical evidence that firms with an ability to use technical infrastructure for knowledge transfer exhibit increased organizational effectiveness (Becerra-Fernandez and Sabherwal, 2001; Gold et al., 2001). Accordingly, we assume that utilization of TCM is positively related to effectiveness of knowledge transfers in the MNC. Similarly, the ability to coordinate between different MNC units, which results in strong structural ties, has been identified as a key mechanism for intra-MNC knowledge transfer (Hansen, 1999; 2002; Bartlett and Ghoshal, 1989; Gupta and Govindarajan, 2000). Intensive collaboration between headquarters and subsidiaries as well as between peer subsidiaries provides a social basis for knowledge exchange (Feinberg and Gupta, 2004; Galunic and Rodan, 1998) and supports knowledge sharing processes within the organization (Hakanson and Nobel, 2001; Dyer and Nobeoka, 2000; Szulanski, 1996; Almeida and Phene, 2004). The organizational development of PCM is critical, as routines have to be established in order to transfer knowledge at a more efficient level, leaving minimal space for causal ambiguity (Simonin, 1999). A strong relationship between sender and recipient will not only ease understanding on a general basis, but will also make the 9 identification of relevant knowledge more plausible. Thus, we expect that higher levels of PCM will have a positive impact on the effectiveness of knowledge transfer. 3.2. The Moderating Effects of Distance Distance affecting international business has commonly been treated as a multi-faceted construct, including cultural, administrative, geographic, and economic dimensions (Ghemawat, 2001). To conceptualize the relationships between organizational units, it is important to differentiate between them as units are not equidistant on all dimensions. But to date only few researchers have conceptually or empirically investigated the dimensions of distance that affect knowledge flows in MNCs. A notable exception is Doz and Santos (1997), who distinguish between spatial “dispersion” (i.e. distribution of knowledge senders and recipients in space) and contextual “differentiation” (e.g. cultural, linguistic, professional differences of knowledge senders and recipients) dimensions of distance. To explore the challenges of managing knowledge under dispersion and differentiation, it is best to start by looking at its anti-pole: The situation of collocation and co-setting. Collocation, the sharing of same location, eases the work of knowledge transfer as it implies a high probability of encounter and frequent action response (c.f. Allen, 1977). Co-setting, the sharing of context, facilitates understanding and the integration of knowledge (Keida and Bhagat, 1998). Under the condition of co-setting, people are part of a similar context, which involves culture, i.e. common verbal, non-verbal language, the use of artifacts, and a common knowledge base. If units within the MNC were not separated through distance, knowledge transfer would work with relative ease. But such a setting hardly ever exists in the MNC. As Doz and Santos (1997) point out: Knowledge transfer becomes ‘eventful’ as managers are confronted with perplexing and uncertain situations. 10 Distance is potentially damaging to knowledge relationships, as “the decay and loss of distance is precisely the decay and loss of knowledge, relationships, and trust, which in turn undermines the ability to act at and over distance” (Goodall and Roberts, 2003, p. 1155). Following this argument, PCM that rely on personal interactions between individuals are likely to be harmed by distance. However, the relational aspect of transfer is expected to be less affected by TCM, which are relatively insensitive to spatial distance as they work 24 hours a day and are accessible from every network node. Information technology allows knowledge to be ‘disembedded’ and ‘decoupled’ from time and space (Giddens, 1990), so that only contextual distance is likely to affect TCM. In particular, the quality of the contents may suffer from abstraction and displacement of their context (Boisot, 1995), as knowledge has to be re-embedded in the new context in order to be used at a distant location (Thompson, 1995). In analytical terms, we posit that dimensions of distance will moderate the relationship between knowledge transfer mechanisms and knowledge transfer effectiveness. Recognizing that distant locations often possess novel knowledge and creative solutions that may be valuable to other units (Shane et al., 1995; Morosini et al., 1998), our argument emphasizes that distance is not necessarily an inhibitor of knowledge flows, but that it affects the effective work of certain transfer mechanisms (see also Tihany et al., 2005; Kirkman et al., 2006). Departing from the relatively trivial situation of collocation and co-setting, we will step-by-step relax these conditions and explore the moderating effects of each dimension of distance. 3.2.1. Spatial Distance Relaxing the condition of collocation, spatial distance is expected to limit knowledge transfer effectiveness. In previous studies, spatial distance has been pointed out to prevent partnering among employees (e.g. Allen, 1977), which constitutes the indispensable basis of knowledge 11 exchange. Focal units may not only be less likely to interact if geographic distance between them is high, but once an interaction is started, obstacles such as different time zones and long transmission channels limit the effectiveness, as the cost and complexity of knowledge search and communication increase with spatial distance (Daft and Lengel, 1986; Cyert and March, 1992). Thus, local dispersion makes coordination difficult and may deter transfers of knowledge through PCM (Zaheer, 1995; Hansen and Lovas, 2004). H1a: The relationship of PCM and knowledge transfer effectiveness is expected to be moderated by geographical distance between sender and recipient. The smaller the geographic distance, the higher the effectiveness of knowledge transfers via PCM. 3.2.2. Contextual Distance Relaxing the second condition of co-setting allows us to gain insights into the impact of contextual distance on the effectiveness of knowledge transfer capabilities. In international business research, national culture has served as the most prominent proxy to model contextual differences between MNC units (e.g. Adler, 1991; Johanson and Vahlne, 1977). As national culture encompasses the values, beliefs and assumptions of a group of people, it also shapes the interpretation of reality and messages (e.g. Hofstede, 2001). Communication as such presupposes that knowledge can be “translated” across cultures (Kim, 1998), but if the two cultural frameworks do not have sufficient commonality, knowledge transfer may be less effective than when the symbolic cultural foundation is consistent (Griffith and Harvey, 2001; Keida and Bhagat, 1998). The characteristics of the resource knowledge require a deep and common ground of understanding between the parties involved in order to extract knowledge that is useful for the recipient. Thus, cultural distance is prone to affect both, TCM and PCM. For PCM, the people involved have to bridge diverse 12 backgrounds, which may result in misunderstandings and prevent the joint solution of problem. Similarly, knowledge transfer via TCM may be inhibited by cultural distance, as it is more difficult to abstract from the context, codify and retrieve the key messages that are valuable for the recipient (Ronen, 1986; Brannen, 2004). H1b: The relationship of PCM and knowledge transfer effectiveness is expected to be moderated by cultural distance between sender and recipient. The smaller the cultural distance, the higher the effectiveness of knowledge transfers via PCM. H2: The relationship of TCM and knowledge transfer effectiveness is expected to be moderated by cultural distance between sender and recipient. The smaller the cultural distance, the higher the effectiveness of knowledge transfers via TCM. Managerially relevant differences between cultures have tended to focus on values. Recent research, however, increasingly suggests extending this discussion to linguistic differences (e.g. West and Graham, 2004; Triandis, 1994). In addition to merely semantic differences, scholars have consistently pointed out that our thinking is affected by our language (Hofstede, 2001; Usunier, 1998; Adler, 1991), and thus may constitute a prime inhibitor in cross-national knowledge reception. Common language facilitates the formation of identity and provides structures for conceptualizing and reasoning (Sapir, 1921; Whorf, 1940). Marschan-Piekkari et al. (1999a; 1999b) found that collaboration across linguistic boundaries frequently involves misunderstandings and, more interestingly, that language acts as a power structure in companies and creates ‘linguistic hierarchies’. Linguistic distance between headquarters and subsidiaries reveals a hierarchy in the 13 organization which does not necessarily coincide with the units’ formal position. Given this evidence we assume that PCM used to transfer knowledge between headquarters and subsidiaries will also be negatively affected by linguistic distance. However, the work of systems is unlikely to be affected by linguistic distance as technical infrastructure is usually designed around one language and people using these systems are likely to be proficient in the respective language. H1c: The relationship of PCM and knowledge transfer effectiveness is expected to be moderated by linguistic distance between sender and recipient. The smaller the linguistic distance, the higher the effectiveness of knowledge transfers via PCM. 4. METHODOLOGY 4.1. Sample Design The European Top 500 served as a sample frame for this study. The research plan involved data collection at two levels, headquarters and subsidiaries. To ensure variety, both in terms of subsidiaries and industries involved, we restricted our sampling efforts to those firms known to operate at least six overseas subsidiaries (Vernon, 1966), whilst on the same hand using direct proportional strata on ten industries to ensure industry variety. An initial target sample of 60 MNCs was set. Data collection started in May 2002. Firms within each strata were contacted in descending order. Whenever a company declined to co-operate in the survey, the next largest company in terms of turnover was approached. Starting with the largest corporations, senior managers from each headquarters were contacted and asked to co-operate. Upon agreement, each was asked to nominate four subsidiaries, which could participate in the study. This sampling procedure led to a final target sample of 300 units, i.e. 60 headquarters and a total of 240 subsidiaries. A standardized mail survey was sent out to all participants. Two follow up rounds and 14 the promise to provide results aimed to ensure a high response. Despite these efforts, and the initial agreement of headquarters, it was impossible to collect responses of all the firms in time. The final sample consisted of 162 MNC units belonging to 48 companies. Thereof 38 headquarters and 124 subsidiaries participated and reported on multiple knowledge transfer relationships within their organization. Each headquarters reported on its knowledge transfer practices with two subsidiaries, and each subsidiary on their interactions with headquarters and a peer subsidiary. This led to a total of 324 transfer relationships, thereof 76 “forward” transfers from headquarters to subsidiaries, 124 “reverse transfers” from subsidiaries to headquarters, and 124 “lateral transfers” from subsidiaries to other subsidiaries. The sample composition shows significant variance. The final sample represents leading MNCs of diverse industries, such as manufacturing (56%), finance and insurance (21%), and other services including consulting companies (11%). Surveyed units operate in 29 countries. The smallest distance between units is 0, i.e. a case where headquarters and subsidiaries located in the same city. The highest distance is 9,910 air miles between Norwegian headquarters in Oslo and a subsidiary in Sydney, Australia. The average headquarters employs 1,019 employees whereas the average number of subsidiary personnel is 638. Although 8.5% of the units have more than 2,500 employees 50% of the sample have a relatively small unit size, i.e. less than 250 employees. Nearly half of the subsidiaries (44%) have been formed as a greenfield, the remaining originated from a merger or acquisition. The unit of analysis in this study was a unit’s knowledge transfers to either headquarters or a subsidiary. To assess non-response bias we tested whether responding firms differed from non- 15 responding firms with respect to size and turnover. Both tests showed non-significant differences between responding and non-responding firms. 4.2. Dependent and Independent Variables The data used in this study came primarily from the questionnaire. As headquarters’ and subsidiaries’ managers were addressed, two slightly different versions of the questionnaire were created. The questionnaires were pre-tested in a series of cognitive interviews with researchers, and managers involved in the research topic. Several amendments, mainly in wording, were conducted before the final instrument was sent to managers. Additional insights were gained through field interviews in different subsidiaries of nine multinational firms to cross-validate our empirical results. A summary of the measures is presented in the Appendix. The following section briefly introduces the operationalization of our variables. 4.2.1. Knowledge Transfer Effectiveness We subscribe to the view that “the key element in knowledge transfer is not the underlying (original) knowledge, but rather the extent to which the receiver acquires potentially useful knowledge and uses this knowledge in own operations.” (Minbaeva et al. 2003, p. 587). The implications are twofold: (1) Not every knowledge transfer results in value added. (2) It is not the replication of a sender’s message by the recipient which is important, but the extent of benefits generated for the recipient’s operations. By applying this definition, we intend to capture effective knowledge transfer in its most holistic way: through the eyes of the beneficiary of this knowledge. Our approach can be seen as an ex-post analysis of knowledge transfer assuming that effective transfer of knowledge will lead to benefits to the recipient’s operations. Put the other way round, high knowledge inflows, which are not translated into an improvement of operations, are 16 considered to be inefficient. The value of knowledge transfer created at the recipient was measured with survey instruments that captured the perceived benefit to the operations from a specific counterpart’s (headquarters or a subsidiary) knowledge transfers across several knowledge domains (1= not at all; 7= a very great deal) (see also Gupta and Govindarajan, 2000). To test the internal consistency of our scale, we calculated Cronbach alpha. The received value of 0.927 is well above the threshold level of 0.70 recommended by Nunally (1978), indicating good internal consistency. We also used a factor analysis to establish the unidimensionality of this scale. The factor score of the resulting one-factor solution was subsequently used in all regressions. 4.2.2. Personal Coordination Mechanisms (PCM) The operationalization of this variable was adopted from Gupta and Govindarajan (2000). The use of coordination instruments in lateral and hierarchical relationships was explored separately. Respondents were asked to indicate how much they relied on liaison personnel, temporary task forces, and permanent teams as means of knowledge sharing in different directions. The scale ranges from 1 (very infrequently) to 7 (very frequently). Cronbach alpha is 0.756, indicating acceptable internal consistency (Nunally, 1978). As above, we conducted a factor analysis to confirm unidimensionality. The factor score was subsequently entered into the models. 4.2.3. Technology-Based Coordiantion Mechanisms (TCM) To assess the units’ ability to use technical infrastructure for inter-unit knowledge transfer, a multiple item construct was created based on Gold et al. (2001) and Becerra-Fernandez and Sabherwal (2001). The items refer to a number of different tools, which are typically part of knowledge management systems. These include tools to map knowledge, team collaboration tools, pointers to expertise, repositories of best practices and lessons learnt. Possible answers range from 17 1 (used very infrequently) to 7 (used very frequently). Cronbach alpha is 0.771, thereby meeting Nunally's (1978) 0.70 level for acceptability. As above, we conducted a factor analysis to confirm unidimensionality. The factor score was subsequently entered into the models. 4.2.4. Geographic Distance We measured geographic distance as the absolute number of airmiles between the two unit locations, the sender and the recipient of knowledge. We logged this measure, as individuals most likely do not perceive that the burdens of travel increase linearly with air miles (see also Hansen and Lovas, 2004). 4.2.5. Cultural Distance Based on the reasoning that actual (dis)similarities in values will hinder or facilitate understanding and the ability to perform a task jointly, cultural distance was measured as the objective distance among the two actors. We used the cultural distance measure introduced by Kogut and Singh (1988) which builds on actual value differences among country pairs through assigning Hofstede’s (2001) cultural value scores to all units. Index values were calculated by summing mean differences over four cultural dimensions after dividing the difference of i-th home and host country scores, by the variance of the i-th dimension. 4.2.6. Linguistic Distance Linguistic distance was measured using a genealogical classification of languages (Grimes, 1992), which captures relatedness of languages in the most comprehensive and conservative way. Applying the methodology of Chen et al. (1995) and West and Graham (2004), we created an 18 index for the distance between languages by counting the number of branches on the language tree necessary to connect the languages of two focal units. 4.2.7. Control Variables As our sample firms operate in diverse industries, we controlled for the industry using a dummy variable coded as “1” for manufacturing and “0” for all service industries. To account for the specificities of each unit, we entered the unit’s size as well as its formal position in the model. Unit size was measured as the (logged) number of employees at the focal unit. A dummy variable for headquarters (1) and subsidiaries (0) served as a proxi for the unit’s formal position. Moreover, we added the number of expatriates in the unit’s top management team. A substantial stream of research has shown that the ability of recipients to connect to the contents of knowledge is crucial (Hansen and Lovas, 2004; Hansen, 2002; Farjoun, 1998; Markides and Williamson, 1994). Anticipating that effective knowledge transfer is facilitated through related prior knowledge, we controlled for the relative competence of the recipient in the respective areas. The recipient unit’s knowledge stock relative to the senders’ (i.e. headquarters or a subsidiary) in different knowledge domains was used as a measure. The knowledge domains mirror those used for the effectiveness measure. Cronbach alpha is 0.797 indicating acceptable internal consistency (Nunally, 1978). In addition, the (dis)similarity of administrative regimes and practices between different units may affect knowledge transfer effectiveness. Asakawa (1995) suggested that institutional isomorphism has a strong impact on a local unit’s approach to structure knowledge and is thus likely to limit the recipient’s motivation and ability to accept and utilize transferred knowledge (Kostova, 1999; Jensen and Szulanski, 2004; Simonin, 1999). A two item scale, capturing the degree of similarity between the transfer partners’ business practices, institutional heritage, and organizational culture was used to measure this construct. Items were adopted from Simonin (1999) and answered on a 19 seven-point scale ranging from “I strongly disagree” to “I strongly agree”. Cronbach alpha for this construct is 0.787, indicating acceptable internal consistency Nunally's (1978). 5. ANALYSIS AND RESULTS 5.1. Statistical Method Moderated multiple regression was used to test our hypotheses. Data was carefully examined with respect to linearity, equality of variance and normality. No serious deviations were detected. We performed a Cook-Weisberg test for heteroscedasticity using Stata 9.0. This test suggested that heteroscedasticity does not appear to be a concern in our data. Similarly, the results of a Harman one-factor test (Podsakoff and Organ, 1986) indicate that common method bias is not a serious problem. As the observations in our sample stem from different MNC units (i.e. headquarters and subsidiaries), we specified fixed-effect models using the robust clustering procedure with Whitecorrected standard errors as implemented in Stata 9.0 (Moulton, 1986; Rogers, 1993, Stata, 2005). The descriptive statistics are reported in Table 1. ************* insert Table 1 about here ************* 5.2. The Moderating Effects of Distance Table 2 presents our findings. Variables were entered sequentially in five blocks. Model 1 only includes the control variables. Our central independent variables, PCM and TCM as well as the three dimensions of distance, were entered in model 2. We constructed six interaction terms by multiplying the (factor score) value for PCM or TCM with each distance dimension, i.e. the logged airmiles for geographic distance, the Kogut and Singh index (1988) for cultural distance, and the linguistic distance index for linguistic distance (Chen et al., 1995). The distance interaction terms were introduced separately in model 3-5. To avoid potential problems due to multicollinearity, we 20 abstained from introducing all distance interaction terms jointly. An overview of all hypotheses and results is given in table 3. ************* insert Table 2 about here ************* ************* insert Table 3 about here ************* The coefficient indicating the unit’s formal position was marginally significant in model 1, but across all other models only the similarity of organizational practices had a significant impact on knowledge transfer effectiveness. None of the other control variables showed significant regression coefficients. In model 2, as expected, both knowledge transfer mechanisms were positively and significantly associated with knowledge transfer effectiveness. The direct effects of geographic, cultural and linguistic distance failed to reach significance throughout. Finally, we present the moderating effects of PCM and TCM in models 3-5. We hypothesized that spatial, cultural and linguistic distance would mitigate the positive effect of PCM on knowledge transfer effectiveness and that TCM would be moderated by cultural distance. To test these moderating effects we introduced interaction effects. In all cases (geographic distance, cultural distance and linguistic distance) we expected that the interaction with knowledge transfer mechanisms reduces knowledge transfer effectiveness. Hence, support for our hypotheses would assume a negative and significant coefficient for the interaction terms. An examination of models 3-5 provides overall support for such a negative effect. The moderating effects of geographic, cultural, and linguistic distance on PCM were supported indicating a significant increase in Rsquare vis-à-vis the base model (model 2) and a negative and significant interaction term. These results imply that any dimension of distance causes problems for the use of PCM. We will return to 21 this point in the discussion section (6.1.). Although the coefficient for the moderating effect of cultural distance and TCM (hypothesis 2) shows the expected sign, it fails to reach significance. We will also elaborate on these non-findings in the discussion section (6.2.). A graphical representation of the interaction effect relationships can be found in figure 2.1 The first of the three lines (dotted line) represents the relationship of knowledge transfer effectiveness and PCM when the distance is low (i.e. mean value minus one standard deviation). The remaining lines represent alterations, setting the distance at the mean values (broken line), and at high levels (i.e. mean value plus one standard deviation) (solid line), which would for example represent dyads of European and Asian units. The positive slope of low geographic and low cultural distance illustrates that the use of PCM increases knowledge transfer effectiveness in these situations. The broken lines in the same diagrams show that this effect is lower, but still positive, if distance increases, i.e. is set to the mean value. In the case of geographic distance we observe a further decrease of this effect for high distance as the line flattens out (no effect), whereas it fully loses its positive effect for cultural distance. Linguistic distance exhibits a slightly different picture as low levels of linguistic distance seem to have no effect and the use of PCM is negatively associated with knowledge transfer effectiveness at medium and high levels of linguistic distance. While these findings are intriguing and suggest that firms may rather use TCM instead of PCM, as they are not affected by distance, one has to be cautious with the interpretation of the above results: The graphs are generated holding all other variables constant at their mean value, which is unlikely to be a realistic assumption. We will further elaborate on the trade-off between PCM and TCM in the managerial implications section (6.3.). 1 To compute this graph we used the estimates from Model 3-5 in Table 2 whilst holding other variables constant at their mean value. 22 ************* insert Figure 2 about here ************* 6. DISCUSSION AND CONCLUSION Our study set out to investigate the impact of knowledge transfer mechanisms on knowledge transfer effectiveness in MNCs. We advance the knowledge in the field of multinational management in several ways. By focusing our investigation on the mechanisms of knowledge transfer instead of characteristics of senders, recipients and knowledge we shed some light on a phenomenon which has for long been regarded as a black box. We introduce a contingency perspective to explain knowledge transfer effectiveness and provide a detailed analysis of the impact of distance by disentangling various dimensions of this broad concept. Moreover, by shifting the attention from the mere inflow of knowledge towards an assessment of the benefits generated through knowledge flows, our study contributes to an emerging field of research, which questions that knowledge flows create value through their mere occurrence (c.f. Haas and Hansen, 2005; Mahnke et al., 2004). The empirical results produced in this paper warrant a discussion along several lines. To begin with, our study indicates that, ceteris paribus, knowledge transfer mechanisms do indeed impact the effectiveness of knowledge transfer. Most important however, our results also confirm that PCM and TCM are differently affected by variations of spatial and contextual distance. 6.1. PCM and the Moderating Effects of Distance The probably most interesting empirical finding is the moderating effect of spatial as well as contextual distance on PCM. Research on knowledge transfer within MNCs has traditionally taken 23 into account spatial or contextual distance as an inhibitor of knowledge flows, but has neglected the fact that distance affects certain knowledge transfer mechanisms more than others (Goodall and Roberts, 2003). With few exceptions (Hansen and Lovas, 2004; Brouthers and Brouthers, 2001), distance has usually been viewed as a direct effect on knowledge flows and other relational variables in the MNC. Recent investigations on the notion of (cultural) distance came to the conclusion, that moderator effects are often more appropriate than direct (negative) effects (Tihany et al., 2005; Kirkman et al., 2006). Especially when distance is associated with knowledge, creativity and innovation there is strong evidence that new knowledge and resources originating in a distant environment are likely to contribute to enhanced MNC performance (e.g. Shane et al., 1995; Morosini et al., 1998). Although studies have mostly focused on cultural distance, these ideas can also be applied to other dimensions of distance. Our results showed that high levels of geographic and linguistic distance are equally harmful to PCM as cultural distance and thus extend our knowledge on the effects of differentiation and dispersion in the MNC (Doz and Santos, 1997). PCM may be particularly sensitive to spatial distance due to the cost and complexity of knowledge search and communication (Daft and Lengel, 1986; Cyert and March, 1992, Haas and Hansen, 2004), whereas contextual distance may complicate knowledge sharing processes due to the different cognitive styles of individuals (Goodall and Roberts, 2003; Bhagat et al., 2002). Our study was among the first in the field of international management as well as knowledge management to introduce the construct of linguistic distance. While language barriers have for long been highlighted in qualitative work (e.g. Marschan-Piekkari et al., 1999a; 1999b), hardly any quantitative study had taken this factor into account. The operationalization we used follows a genealogical or genetic classification, which identified dissimilarity of languages based on the existence of inference of common linguistic ancestors (see also West and Graham, 2004). 24 This method generates a more comprehensive classification than measures focusing only on vocabulary, syntax or morphology and is thus likely to reflect different approaches in cognition, reasoning or conceptualizing which impede understanding. However, we acknowledge that the available measure is very coarse-grained and the development of more sophisticated measures of linguistic distance in the future is warranted. As in many other studies, the measure of cultural distance in our analysis was empirically constructed on the basis of Hofstede’s value differences using the methodology suggested by Kogut and Singh (1988). Recently this measure has received increasing criticism (c.f. Shenkar, 2001). In the context of our study, which is concerned with the impact of different dimensions of distance on knowledge transfer mechanisms, the most pertinent questions concerns the aggregation of Hofstede’s value scores. I.e. Is the moderating effect on PCM driven by a single dimension of value differences? To investigate this issue, we ran the models with the separate Hofstede dimensions. As shown in Table 4, power distance does not support our hypothesized relationship while all other dimensions show a negative and significant coefficient, confirming that the aggregation of the Kogut and Singh index does not drive the results of our main regression (see table 2, model 4). ************* insert Table 4 about here ************* 6.2. The Insensitivity of TCM As predicted, we found a direct and significant effect for TCM on the effectiveness of knowledge transfer. In other words, organizations that invest in and build up capabilities around their technical infrastructure will achieve higher benefits than firms that do not. But our findings show that these 25 capabilities are not moderated by variations in spatial and contextual distance. While our results confirm a strong contextual dependence of PCM, TCM appear to be largely context-free. One potential explanation is that due to the codified nature of the underlying knowledge ambiguity is limited. Several streams of literature (e.g. Daft and Lengel, 1994; Nonaka and Takeuchi, 1995; Hansen et al., 1999) come to the conclusion that codified knowledge is easier to store and transfer in technical and less “rich” media. Thus, users of systems may be able to choose the right issues and data formats for transfers that can be easily de-contextualized and re-contextualized in the new environment (e.g. Giddens, 1990; Brannen, 2004; Bhagat et al., 2002; Schulz and Jobe, 2001). Notwithstanding the fact that not all knowledge within an organization can be transferred via technological systems, these findings spur interesting speculations about the applicability of TCM over PCM in situations of high dispersion and differentiation. 6.3. Managerial Implications and Concluding Remarks Our findings have some interesting managerial implications as well. The negative relationship between PCM used in situations of high distance and the effectiveness of knowledge transfers raises concerns about the usability of PCM in the MNC context where transfers regularly occur between organizational units located in distant countries. To shed more light on the potential tradeoffs firms face when deciding to develop PCM or TCM, we computed three graphs (Figure 3) showing the effect of high levels PCM and high levels of TMC on knowledge transfer effectiveness in different situations of distance. ************* insert Figure 3 about here ************* Keeping all other variables constant at their mean values, the first diagram illustrates the effectiveness of high TCM as well as high PCM for increasing levels of geographic distance. In 26 line with our main findings, the graph shows that the use of PCM is favorable in situations of low geographic distance, as personal mechanisms such as face-to-face meetings may allow smoother transfer of knowledge. However, as geographic distance increases, we observe a steep negative slope of PCM, indicating that its contribution to knowledge transfer effectiveness decreases dramatically. The black line representing highly developed TCM also shows a slightly negative slope but is not heavily affected by distance. For example, it does not make a big difference whether you send an email to the office next door or from New York to Shanghai. In this graph, which is based on our empirical database, we do not see an intersection of the two lines. However, the question whether PCM are always better than TCM is somewhat more complicated than the graph suggests as we do not take into account potential cost differences for developing those knowledge transfer mechanisms. The second graph shows a comparison of high PCM and high TCM across different levels of cultural distance. Again assuming that an organization incurs the same costs to develop either mechanism, the intercept of the two capabilities signifies the distance upon which TCM become a superior mode of transfer. For our study this intercept is at 2.4. In other words, for transfers to cultures below this point (e.g. most dyads located within the European Union) PCM are more effective than TCM. Beyond this point managers of multinational firms might be better advised to invest in TCM, whose effectiveness is not compromised by cultural distance. A third graph was computed for linguistic distance, which shows a superiority of TCM already at low levels of linguistic distance and a relatively steep decrease of PCM’s effect on knowledge transfer effectiveness. Due to the limitations of our measurement and the novelty of the concept of linguistic distance in international business literature, we can only speculate on the 27 meaning of these results. A logic which supports the underlying relationship in this graph is that within a language family (e.g. Slavic languages) people may still be able to read and understand knowledge transferred via TCM while it may be impossible for them to participate in discussions or negotiations needed for PCM. But further interpretations of this issue probably require modeling beyond linear representations. The primary aim of this study was to uncover how two different knowledge transfer mechanisms work to achieve effective knowledge transfer in situations of dispersion and differentiation. Our results support the claims of recent studies that distance (still) matters in international business (Ghemawat, 2001; Nachum and Zaheer, 2005). More specifically, we found that firms should carefully adjust their transfer mechanisms to the distance between sender and recipient in order to achieve the most effective knowledge transfer. On a more conceptual level, we opened the floor for a contingency perspective on knowledge flows by focusing on the coalignment of knowledge transfer mechanisms and different dimensions of distance and we are confident that more insights in this area will follow in due course. In particular, studies investigating potential reinforcing effects of the development of mechanisms and knowledge transfer effectiveness may constitute fruitful avenues for further research 28 ACKNOWELDGEMENTS We would like to thank Julian Birkinshaw, Michael Mayer, L.
