This paper argues that existing matching models with unemployment as an active search and nonparticipation as an inactive search predict counterfactual results: the unemployment rate is at most two times as volatile as the employmentpopulation ratio; only 20 percent of the actual volatility of...

This paper surveys the use of search and matching models in macroeconomics. It outlines the standard model, discusses its extensions, presents alternative formulations, considers the empirical evidence, and studies applications to macroeconomic questions such as business cycles, growth, and...

Payroll taxes represent a major distortionary in uence of governments on labor markets. This paper examines the role of payroll taxation and the social safety net for cyclical fluctuations in a nonmonetary economy with labor market frictions and unemployment insurance, when the latter is only...

The labor search and matching model plays a growing role in macroeconomic analysis. This paper provides a critical, selective survey of the literature. Four fundamental questions are explored: how are unemployment, job vacancies, and employment determined as equilibrium phenomena? What...

If entitlement to Unemployment Insurance (UI) benefits must be earned with employment, generous UI is an additional benefit to an employment relationship, so it promotes job creation. If individuals are risk neutral, UI is fairly priced, and the UI system prevents moral-hazard, the generosity of...

Payroll taxes represent a major distortionary influence of governments on labor markets. This paper examines the role of payroll taxation and the social safety net for cyclical fluctuations in a nonmonetary economy with labor market frictions and unemployment insurance, when the latter is only...

Two papers have recently questioned the quantitative consistency of the search and matching models. Shimer (2005) has argued that a text-book matching model is unable to explain the cyclical variation of unemployment and vacancies in the U.S. economy. Costain and Reiter (2007) have found the...

This paper studies the implications of labor taxation in determining the sensitivity of an economy to macroeconomic shocks. We construct a New Keynesian business cycle model with matching frictions of the labor market, where sluggish employment adjustment implies a key role for labor markets in...

Incorporating labor market search in general equilibrium models has been shown to generate realistic dynamics in employment, job creation, and job destruction and to increase the magnitude and persistence of the impact of productivity shocks on output. This paper studies the extent to which the...

In the past decades several features of U.S. unemployment dynamics have been investigated empirically. The original focus of research was on the duration of unemployment. In later studies the cyclicality of incidence and duration, compositional effects and duration dependence of the exit rate...
