“Reviewing Path Dependence Theory in Economics: Micro–Foundations of Endogenous Change Processes”

This paper proposes a critical review of some of the main applications of path-dependence in economic theory. In particular, it calls attention on those theories clarifying the micro-foundations of path-dependent processes in economics. In the field of innovation, path-dependence shows the endogenous character of technological change, revealing the complex interplay among firm’s structural specificities, irreversibility, creativity, localized learning, externalities, feedbacks and contingent disturbing factors. In cognitive and institutional economics, the path-dependent character of learning processes, shown by cognitive and neurobiological studies, suggests interesting explanations for economic and institutional inefficiency persistence and, in general, for institutional genesis and evolution processes. Micro-foundations of economic path-dependence offer new opportunities for further extending theoretical and empirical economic research. For instance, they could contribute to extend economic self-organization approach, which has focused on the non-linear character of economic dynamic processes and has described economic systems as dissipative and entropic structures. In this sense, path-dependence represents a fertile tool for further clarifying economic and institutional dynamics and a precious opportunity of interdisciplinary research.
