The author introduces risk-averse preferences, labor-leisure choice, capital, individual productivity shocks, and market incompleteness to the standard Mortensen-Pissarides model of search and matching and explore the model's cyclical properties. There are four main findings. First and foremost,...

This paper studies the quantitative properties of a multiple-worker firm matching model with on-the-job search where heterogeneous firms operate decreasing-returns-to-scale production technology. The authors focus on the model's ability to replicate the business cycle features of job flows,...

Labor market frictions are able to induce sluggish aggregate employment dynamics. However, these frictions have strong implications for the source of this propagation: They distort the path of aggregate employment by impeding the flow of labor across firms. For a canonical class of frictions, we...

Revised May 2016. We analyze a labor market with search and matching frictions in which wage setting is controlled by a monopoly union. Frictions render existing matches a form of firm-specific capital that is subject to a hold-up problem in a unionized labor market. We study how this hold-up...

An equilibrium model with firm and worker heterogeneity is constructed to analyze labor market and welfare implications of the Patient Protection and Affordable Care Act, commonly called the Affordable Care Act (ACA). The authors' model implies a significant reduction in the uninsured rate from...

First version: December 18, 2014. This version: January 12, 2015. This paper proposes and implements a statistical methodology for adjusting employment data for the effects of deviation in weather from seasonal norms. This is distinct from seasonal adjustment, which only controls for the normal...

This paper reviews recent approaches to modeling the labour market and assesses their implications for inflation dynamics through both their effect on marginal cost and on price-setting behavior. In a search and matching environment, we consider the following modeling setups: right-to-manage...

This paper develops a real business cycle model with labor market search and matching frictions, which endogenously links both the cyclical fluctuations and the mean level of unemployment to the aggregate business cycle risk. The key result of the paper is that business cycles are costly for all...

In a reasonably calibrated Mortensen and Pissarides matching model, shocks to average labor productivity can account for only a small portion of the fluctuations in unemployment and vacancies (Shimer (2005a)). In this paper, the author argues that if vintage specific shocks rather than aggregate...

Using U.S. Census microdata, the authors show that, on average, workers change occupation and industry less in more densely populated areas. The result is robust to standard demographic controls, as well as to including aggregate measures of human capital and sectoral mix. Analysis of the...
