Modeling Inefficient Institutions ∗

Many economists and social scientists have recently emphasized the importance of government policies, economic, political and legal institutions, and more broadly, the organization of society.1 There is also mounting evidence that various institutional features are indeed important for economic growth.2 Nevertheless, despite important theoretical advances, we still lack an organizational framework to analyze the determinants of institutions.3 In particular, if institutions matter (so much) for economic performance, why do societies choose or end up with institutions that do not maximize economic growth or aggregate economic welfare? This paper discusses potential answers to this question. The main focus is on modeling the emergence and persistence of inefficient institutions, meaning institutions that do not maximize the growth potential of a society.4 The purpose of the paper is not to provide a survey but to construct a relatively simple unified model that illustrates both various issues already raised in the existing literature and a number of new mechanisms that appear to be important in understanding inefficient institutions.
