Transaction costs, social institutions, and the duration of interfirm contracts in China

Interfirm contracts are a ubiquitous economic institution in market economies. In this study, we examine the determinants of one important aspect of interfirm contracts – contract duration. We begin with Joskow's (1987) study that demonstrated that contract duration is governed by mechanisms that economize transaction costs. Our study extends Joskow's study in several ways: First, while Joskow's study focuses on one particular area of extreme resource dependence, between the coal mine and the power company, we examine patterns of contract duration and their determinants across broader economic sectors, thereby providing a more general test of the key ideas in transaction cost economics. Second, we investigate the role of social institutions as a distinct mechanism underlying the design of contract duration, especially in terms of mitigating risks and transaction costs. Finally, by situating our study in China, we extend the research context beyond industrialized market societies to a transitional economy where interfirm contracts are an emerging economic institution. The empirical study is based on the analyses of information on 877 contracts from 620 firms collected in two Chinese cities, Beijing and Guangzhou, in 2000.
