We build a model of firm-level innovation, productivity growth and reallocation featuring endogenous entry and exit. A new and central economic force is the selection between high- and low-type firms, which differ in terms of their innovative capacity. We estimate the parameters of the model...

We build a model of firm-level innovation, productivity growth and reallocation featuring endogenous entry and exit. A key feature is the selection between high- and low-type firms, which differ in terms of their innovative capacity. We estimate the parameters of the model using detailed US...

Why do inefficient - non-growth enhancing - institutions emerge and persist? This paper develops a simple framework to provide some answers to this question. Political institutions determine the allocation of political power, and economic institutions determine the framework for policy-making...

Do societies choose inefficient policies and institutions? An extension of the Coase theorem to politics would suggest the answer is no. This paper discusses various approaches to political economy and develops the argument that there are strong empirical and theoretical grounds for believing...

Do societies choose inefficient policies and institutions, in contrast to what would be suggested by a reasoning extending the Coase Theorem to politics? Do societies choose inefficient policies and institutions because of differences in the beliefs and ideologies of their peoples or leaders? Or...
