Why do some people become entrepreneurs, how do institutions affect this choice, and how does this affect the firm size distribution and aggregate productivity? This paper addresses this question using a matching model with occupational choice and heterogeneity in both ability as a worker and ex...

Why do some people become entrepreneurs (and others don't)? Why are firms so heterogeneous, and many firms so small? To start, the paper briefly documents evidence from the empirical literature that the relationship between entrepreneurship and education is Ushaped; that many entrepreneurs start a...

Labor Force States and flows between are useful tools to model individual dynamics in the labor market. This chapter reviews recent literature uncovering substantial heterogeneity in transitions across Labor Force States. We review methods and results by replicating leading studies using...

Over the last 40 years the US tax system went through striking changes that considerably reduced the progressivity of the system. This resulted in a dramatic reduction of effective tax rates on top income groups. This paper investigates the macroeconomic repercussions of this change in tax...

This paper analyzes the effect of firing costs on aggregate productivity growth. For this purpose, a model of endogenous growth through selection and imitation is developed. It is consistent with recent evidence on firm dynamics and on the importance of reallocation for productivity growth. In...

The aim of this paper is to contribute to explaining differences in aggregate productivity between similar, industrialized countries such as the US and European Union (EU) member states. By introducing shifts in administrative entry cost and a firm technology adoption decision in a model of...

How do firing costs affect aggregate productivity growth? To address this question, a model of endogenous growth through selection and imitation is developed. It is consistent with recent evidence on firm dynamics and on the importance of reallocation for productivity growth. In the model,...

"Entrepreneurs out of necessity" identified by the Global Entrepreneurship Monitor survey are a sizeable group across countries. They tend to have low education, run smaller firms, expect their firms to grow less, but are likely to stay in the market. This evidence is a challenge for existing...

This paper analyzes the effect of firing costs on aggregate productivity growth. For this purpose, a model of endogenous growth through selection and imitation is developed. It is consistent with recent evidence on firm dynamics and the contribution of firm entry and exit to aggregate...
