While some researchers have examined the relationship between interfirm trust and alliance performance (Inkpen and Curall, 1998; Luo,2002; Sako, 2000; Zaheer et aL, 1998), others have argued that several factors such as risk and uncertainty, cultural diversity of partners, and resource dependence (Elangovan and Shapiro, 1998; Luo, 2002) affect the relationship between trust and alliance performance. Thus, there is a need for research into the role of other social exchanges such as reciprocal resource commitments and relational influence between partners that will ensure collaboration and alliance success. Because reciprocity and mutual influence between partners are tangible norms and manifest as mutual control and power sharing or joint decision making, they can very well supplement trust in collaboration. In addition, there is a need lo understand why a partner will have a greater or lesser amount of trust for another party. That is, what are the specific attributes of the partners that enhance trust in the alliance? In this study, we conceptualize trust in terms of trustworthiness based on skills, integrity, and benevolent attitudes of the partner as perceived by the focal firm, and examine the managerial perceptions related to all significant ongoing social exchanges between alliance partners. Since most conflicts occur in the routine aspects of the interaction, successful alliance management is essentially a social process. From the focal firms' perspective, we examine the relationships between social exchanges (reciprocity, trust, and mutual influence) and alliance success in terms of perceived alliance performance and partner's propensity to continue the alliance.
