We develop a dynamic general equilibrium model where workers can engage in search while on the job. We show that on-the-job search is a key component in explaining labor market dynamics in models of equilibrium unemployment. The model predicts fluctuations of unemployment, vacancies, and labor...

We present and discuss the simple search and matching model of the labor market against the background of developments in modern macroeconomics. We derive a simple representation of the model in a general equilibrium context and how the model can be used to analyze various policy issues in labor...

We demonstrate the possibility of indeterminacy and nonexistence of equilibrium dynamics in a standard business cycle model with search and matching frictions in the labor market. Our results arise for empirically plausible parameterizations and do not rely on a mechanism such as increasing returns.

We analyze the implications of intra-firm bargaining for business cycle dynamics in models with large firms and search frictions. Intra-firm bargaining implies a feedback from the marginal revenue product to wage setting, which leads firms to over-hire in order to reduce workers' bargaining...

We develop a business cycle model with search and matching frictions in the labor market and show that on-the-job search generates substantial amplification and propagation. Rising search by employed workers in an expansion amplifies the incentives of firms to post vacancies. By keeping job...

Recent research shows that observed labor market flows can be explained in search and matching models only by assuming either implausibly large productivity shocks (Hall 2003) or an excessively high degree of real wage rigidity even for new hires (Shimer 2003). If this is not the case, the...

The New Keynesian Phillips curve explains inflation dynamics as being driven by current and expected future real marginal costs. In competitive labor markets, the labor share can serve as a proxy for the latter. In this paper, we study the role of real marginal cost components implied by search...
