Path Dependence, Agency and Technological Evolution

Abstract
The notion of path dependence is regularly deployed to account for the way past commitments have an important bearing on current choices. We make a distinction between the notions of past and path dependence and focus on path dependence as two types of event sequences: selfreinforcing and reactive. We then address the issue of how the notion of path dependence can be reconciled with a temporal-relational perspective on agency. These notions are tested and refined using a longitudinal case study of ICI's move away from chlorofluorocarbons (CFCs) and the decision to build three plants to produce one CFC alternative (HFC-134a) for the global refrigeration market. The paper concludes with a discussion of the implications of path dependence for research on technological and firm evolution.
