Shimer (2005) demonstrated that aggregate productivity shocks in a standard matching model cause fluctuations in key labor market statistics---such as the job-finding rate, the vacancy/unemployment ratio, and the unemployment rate---that are too small by an order of magnitude. This paper shows...

This paper points out an empirical failing of real business cycle models in which unemployment is endogenized through a matching function. One can easily choose a calibration to make the cyclical fluctuation in unemployment as large in the model as it is in the data, or to make the response of...

This paper proposes an explanation for observed differences in the business cycle volatility of employment and unemployment across a sample of OECD countries. Using an incomplete markets variant of the fair wage real business cycle model, increases in the gross replacement rate of public...

Standard macroeconomic models underpredict the volatility of unemployment fluctuations. A common solution is to assume wages are rigid. We explore whether this explanation is consistent with the data. We show that the wage of newly hired workers, unlike the aggregate wage, is volatile and...

This paper studies the interaction of financing constraints and labor market imperfections on the labor market and economic activity. My analysis builds on the agency cost framework of Carlstrom and Fuerst [1998. Agency costs and business cycles. Economic Theory, 12(3):583-597]. The aim of this...

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...

Shimer (2015) argues that a search and matching model of the labor market in which wage is determined by Nash bargaining cannot generate the observed volatility in unemployment and vacancy in response to reasonable labor productivity shocks. This paper examines how incorporating monopolistically...

This paper studies how the elasticity of intertemporal substitution (EIS) influences labor market fluctuations in the labor search and matching model with both extensive and intensive margins of labor supply. With the curvature of utility, the countercyclical marginal utility of consumption...

Shimer (2015) argues that a search and matching model of the labor market in which wage is determined by Nash bargaining cannot generate the observed volatility in unemployment and vacancy in response to reasonable labor productivity shocks. This paper examines how incorporating monopolistically...

We reassess the role of vacancies in a Diamond-Mortensen-Pissarides style search and matching model. In the absence of free entry long lived vacancies and endogenous separations give rise to a vacancy depletion channel which we identify via joint unemployment and vacancy dynamics. We show...
