Although extant literature has shown that formal contracts and relational governance play a key role in interorganizational relationships, the nature of their interplay still remains equivocal. To better understand the relationships between contractual and relational governance, we conducted a qualitative review and meta-analysis of the existing literature. Meta-analytic results from 33,051 interorganizational relationships across 149 empirical studies have indicated that contractual governance is positively related to both sides of relational governance-trust and relational norms. Our results have also indicated that contracts, trust, and relational norms jointly improve satisfaction and relationship performance and jointly reduce opportunism. These findings provide strong evidence for the complementarity arguments of the contractual-relational governance relationships and their joint impacts on performance. We also found that the mutual relationships between contractual and relational governance are moderated by the institutional environments, the interorganizational relationship type and length, and the construct measurement of contracts. Overall, this study provides new insights on when contractual and relational governance complement or substitute each other. We discuss the implications of our study for theory and practice and propose a research agenda for future research on governance in interorganizational relationships.

Abstract. Leveraging a longitudinal dataset concerning 102 inter-firm disputes, we evaluate the effects of contract structure on trust and on the likelihood of continued collaboration. We theoretically refine and empirically extend prior research by (a) distinguishing between control and coordination functions of contracts, (b) separating goodwill-based and competence-based trust, and (c) evaluating the effects of contract structure on relational outcomes in the context of disputes. We find that control provisions increase competence-based trust, but reduce goodwillbased trust, resulting in a net decrease in the likelihood of continued collaboration. Coordination provisions increase competence-based trust, leading to an increased likelihood of continued collaboration.

Despite the scholarly interest in contracts and trust governing interorganizational relationships, an understanding of how contracts influence trust remains limited by the way in which the interaction between the two constructs is conceptualized. By bringing together recent advances in the literature on interorganizational governance, I consider (a) the controlling and the coordinating dimensions of formal contracts, (b) trust and distrust as two distinct constructs, and (c) both the calculative and noncalculative aspects behind the development of trust and distrust. Drawing upon information-processing theory, I develop a series of propositions about how each contractual dimension influences the development of trust and distrust by inducing specific information-processing and decision-making mechanisms. My theoretical analysis leads me to discuss the trade-offs inherent in governance choices, and I discuss the implications of my propositions for the literature on interorganizational governance mechanisms.

a b s t r a c tThis paper theoretically refines and empirically extends the debate on the type of interplay between relational experience and contractual governance in an under-researched area: supply chain disputes. We define relational experience as either cooperative or competitive; distinguish between control and coordination functions of contractual governance; and assess their interplay on the negotiation strategy used in disputes. Using a unique data set of buyer-supplier disputes, we find, in particular that increasing contractual control governance weakens the positive effect of cooperative relational experience on cooperative negotiation strategy. However, increasing contractual control governance for a buyer-supplier dyad with competitive relational experience will increase cooperative negotiation strategy. Contractual coordination governance reinforces the positive effect of cooperative relational experience. Through this study, we reach a better understanding of how and when contractual and relational governance dimensions interact; rather than whether they act as substitutes or complements as has been studied in prior research. We discuss the implications of these findings for the field of supply chain management.
