We develop a framework where mismatch between vacancies and job seekers across sectors translates into higher unemployment by lowering the aggregate job-finding rate. We use this framework to measure the contribution of mismatch to the recent rise in U.S. unemployment by exploiting two sources...

In this paper we propose a dynamic partial equilibrium model in order to explain the search behaviour of low-skilled non employed workers, when their employability decreases as the unemployment spell lengthens. We show that the unemployed react to a reduction in their current search...

This paper offers a theoretical exploration and empirical outlook towards a triptych heretofore not properly investigated: atypical work (e.g., self-employed, agency workers, and workers with a fixed-term contract), participation within the firm, and innovation. How, it must be asked, can and...

Microeconomic data on individual firms and employer-employee matches reveal substantial and persistent dispersion in firm size, productivity, and average wage paid and a positive correlation between each pair. To the extent that intrinsic differences in firm productivity explain these facts,...

In this paper I explore optimal employment contract design in a random search framework, where workers search on and off the job for employment opportunities similar to that of Lentz (2010) and Bagger and Lentz (2013). The worker determines the frequency by which employment opportunities arrive...

We provide an illustration of how the design of labor market clearing mechanisms can affect incentives for human capital acquisition. Specifically, we extend the labor market matching model (with discrete transfers) of Kelso and Crawford (1982) to incorporate the possibility that agents may...

This paper models growth via on-the-job learning when firms and workers are heterogeneous. It is an overlapping generations model in which young agents match with the old. More efficient assignments lead to faster long-run growth, more inequality, and less turnover in the distribution of human...

Teacher contracts that condition pay and retention on demonstrated performance can improve selection into and out of teaching. I study alternative contracts in a simulated teacher labor market that incorporates dynamic self-selection and Bayesian learning. Bonus policies create only modest...

Managers´ incentives to invest in firms´ specific activities (internal investments) are compared with those to realize activities to increase their alternative market opportunities (external investments) when a managerial contract establishes a large breach penalty in the event of employment...

Workers change occupation and industry less often in more densely populated areas, a relationship that had not been previously reported. This reduced-form result is robust to standard demographic controls, as well as to including aggregate measures of human capital and sectoral mix. Analysis of...
