Access to intrafirm knowledge is obtained through two independent knowledge-based exchanges within internal knowledge markets: account managers invest in different activities in order to signal communal and deal-maker reputations. In exchange, colleagues share organizational and expertise knowledge that ultimately contribute to account managers' performance. The types of knowledge shared by colleagues depend on the reputations of account managers. http://repub.eur.nl/res/pub/18402/ 2009-03-01T00:00:00Z This study investigates the impact of selection criteria associated with interpersonal interaction (such as good personal relationships) on supplier consideration. More specifically, it examines how the importance of these criteria depends upon service-related dimensions. This is an experimental study among client firms in the market research industry, which combines a conjoint and between-subjects design to lead to several new insights. First, while good personal relationships play an important role in the selection of a service provider, their impact increases if the service offering is subjective in nature, but it decreases if it is strategically important. Second, enriching the service offering with interpretation and advice is more important for subjective as well as for strategically important service offerings. Third, as to other selection criteria, the study results show some interesting differences between consideration and choice. Price has a substantive impact on choice alone, while a strong brand name is helpful for the service provider only in the consideration stage. http://repub.eur.nl/res/pub/12691/ 2007-05-01T00:00:00Z We investigate social circles in intra-firm settings. First, we argue that social circles are inhabited by individuals whose attitudes display fit with the objectives of the social circle rather than more self-centered instrumentalism or calculation. For a test of this hypothesis, we distinguish between friendship circles and strategy-influence circles. We find that friendship circle membership is positively associated with attitudes that display empathic concern but negatively with more instrumental attitudes, whereas strategy-influence circle membership is positively associated with attitudes that display long-term ambition but negatively with attitudes that display short-term calculation. Second, we argue and find that membership of social circles affects individual performance (social circles foster the exchange of information, for which we find clear evidence), albeit not necessarily in a linear fashion. Our new insights into social circle membership and performance implications can guide individuals in seeking access to such social circles and can aid management in understanding and perhaps influencing intra-firm knowledge flows. http://repub.eur.nl/res/pub/7899/ 2006-08-22T00:00:00Z We investigate social circles in intra-firm settings.

Using social network theory, the authors investigate buyers' preferences for specific patterns of relationships among buyers, intermediary vendors, and suppliers of complex products. Using a conjoint experiment with actual and prospective buyers of integrated computer networks and services, the authors find that beyond their dyadic interaction with a vendor, buyers take into account the buyer-vendor-supplier triad. Specifically, buyers value sequences of selective strong ties as well as sequences of more numerous weak ties. This is consistent with theoretical propositions that strong ties facilitate the mobilization of support and the transfer of complex knowledge, whereas nonoverlapping weak ties facilitate the gathering of intelligence and the monitoring of new developments. The authors find only mixed evidence that buyers value direct access to suppliers when strong ties exist between the vendor and suppliers, as predicted by the third-party sanctioning argument in social network theory. In addition, they find that interaction intensity and valence do not always have the same effects, thus providing criterion validation to the bidimensional nature of tie strength that has been documented in previous research. http://repub.eur.nl/res/pub/1126/ 2004-01-19T00:00:00Z This article provides empirical tests of the hypothesis of ‘optimal cognitive distance’, proposed by Nooteboom (1999, 2000), in two distinct empirical settings. Variety of cognition, needed for learning, has two dimensions: the number of agents with different cognition, and differences in cognition between them (cognitive distance). The hypothesis is that in interfirm relationships optimal learning entails a trade-off between the advantage of increased cognitive distance for a higher novelty value of a partner’s knowledge, and the disadvantage of less mutual understanding. If the value of learning is the mathematical product of novelty value and understandability, it has an inverse-U shaped relation with cognitive distance, with an optimum level that yields maximal value of learning. With auxiliary hypotheses, the hypothesis is tested on interfirm agreements between pharmaceutical companies and biotech companies, as well as on interfirm agreements in ICT industries. http://repub.eur.nl/res/pub/1166/ 2004-01-19T00:00:00Z Account managers invest in two distinct, compensatory social ties to achieve social capital, namely peripheral knowledge ties and implementation support ties. The first ties require communal investments, which consist of organizational citizenship behaviors and peripheral information sharing. The second ties require instrumental investments that encompass reciprocity norms and strategic information sharing. Hypotheses are tested on a sample of 164 account managers who sell financial products/services to large customers. The findings show that account managers invest in both ties to attain peripheral knowledge accretion and implementation support which in turn result in improved performance. http://repub.eur.nl/res/pub/92/ 2001-05-21T00:00:00Z Prior research on technology-intensive (TI) markets makes abstraction of the social context in which transactions take place. In contrast with this prior literature, the authors show that buyer-vendor transactions in TI markets are relationally and structurally embedded in an interfirm network. Their main premise is that buyers in TI markets prefer vendors with whom they can share a strong tie, and that in turn buyers want these vendors to share strong ties with their component manufacturers. This is an important addition to TI literature and to the on-going debate on the strength of ties in the sociology, management and marketing literatures. The authors also specifically consider how characteristics focal to TI markets, such as the know-how buyers possess or the pace of technological change they perceive, affect the extent to which buying behavior is relationally and structurally embedded. An empirical test in the computer network market shows good support for the developed theory.
