The relation between trust and transaction costs in interorganizational relationships

Based on the assumption that trust is a mechanism of relational governance, which can influence the costs associated with the formation, development and maintenance of interorganizational relationships, in this article one aims to test the relation between trust and transaction costs in these relationships. Based on the literature on trust and on transaction costs, one puts forward four new hypotheses, which suggest a negative relation between trust and costs of information, of negotiation, of implementation and of monitoring in interorganizational relationships. These hypotheses were tested using multiple regression analysis in a quantitative case study where the buyer is illustrated by an automaker and its suppliers are represented by a sample of the major ones. The results suggest that there are significant, yet negative relations between trust and costs of negotiation and of monitoring. The relations between trust and costs of information and of implementation, in turn, are not statistically significant. We believe that these results represent a more-fined grained understanding of the relation between trust and transaction costs in interorganizational relationships to the degree that it is suggested that the four types of transaction costs are not perfectly correlated.
