We investigate optimal rewards in an R&D model where substitute ideas for innovation arrive to random recipients at random times. By foregoing investment in a current idea, society as a whole preserves an option to invest in a better idea for the same market niche, but with delay. Because...

In the U.S., the cross-state differences in unemployment rates are large - for instance, large compared to variations in the national unemployment rate over time. At the same time, there is considerable labor mobility within the U.S.; in fact, enough that, if migration arbitrages differences in...

This paper specifies and estimates a structural model of home seller behavior. The model is an application of search theory to housing and is estimated using method of moments. The estimation method uncovers an analytical closed-form relationship between reduced- form coefficients of hedonic and...

We analyze the effects of income support on unemployment and welfare dynamics when stigma is attached to welfare provision. Stigma has been modeled in the literature as a cost of welfare participation; in this paper we analyze the effect of income support on unemployment and welfare dynamics by...

Unemployment benefit systems are nonexistent in many developing economies. Introducing such systems poses many challenges which are partly due to the high level of informality in the labor markets of these economies. This paper studies the consequences on the labor market of implementing an...

The contributions to economic theory by Dale Mortensen (1939–2014) are reviewed and commented with a particular emphasis on the collaboration in the theory of equilibrium unemployment.

This paper explores the links between unemployment, retirement and their associated public insurance programs. It is a contribution to a growing body of literature focused on a better understanding of the labor behavior of advanced-age workers, which has gained importance as the pension crisis...
