A rich but tractable variant of the Burdett-Mortensen model of wage setting behavior is formulated and a dynamic market equilibrium solution to the model is defined and characterized. In the model, firms cannot commit to wage contracts. Instead, the Markov perfect equilibrium to the wage setting...

Productivity dispersion across firms is large and persistent, and worker reallocation among firms is an important source of productivity growth. The purpose of the paper is to estimate the structure of an equilibrium model of growth through innovation that explains these facts. The model is a...

Shimer (2005a) argues that the Mortensen-Pissarides equilibrium search model of unemployment explains only about 10% of the response in the job-finding rate to an aggregate productivity shock. Some of the recent papers inspired by his critique are reviewed and commented on here. Specifically, we...

We study a multi-sector model of growth with differences in TFP growth rates across sectors and derive sufficient conditions for the coexistence of structural change, characterized by sectoral labor reallocation, and balanced aggregate growth. The conditions are weak restrictions on the utility...

This paper derives optimal employment contracts when workers are risk averse and there are employment and unemployment risks. Without income insurance, consumption rises during employment and falls during unemployment. Optimal employment contracts offer severance compensation and sometimes give...

We study long-run trends in market hours of work and employment shifts across economic sectors driven by uneven TFP growth in market and home production. We focus on the substitutions between market and home production and on the structural transformation between agriculture, manufacturing and...

In this paper we study the contribution of inflows and outflows to the dynamics of unemployment in three European countries, the United Kingdom, France and Spain. We compare performance in these three countries making use of both administrative and labor force survey data. We find that the...
