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...

This paper provides a new explanation of why inflation is sluggish in response to aggregate demand shocks and why aggregate output changes as result of such shocks. We argue that these phenomena are related to lags between inputs and outputs in the production process, "production lags" for...

Existing models of equilibrium unemployment with endogenous labor market participation are complex, generate procyclical unemployment rates and cannot match unemployment variability relative to GDP. We embed endogenous participation in a simple, tractable job market matching model, show...

Using a Cox proportional hazard model that allows for a flexible time dependence in order to incorporate business cycle effects, we analyze the determinants of reemployment probabilities of young workers in the U.S. from 1978-1989. We find considerable changes in the chances of young workers...

The paper explores the consequences of macroeconomic policy for labor market outcomes in the presence of frictions. It shows how policy may be useful in overriding frictions, as well as how it might generate adverse outcomes. The analysis looks at the main tools of macroeconomic policy and...

Shimer (2005a) argues that the Mortensen-Pissarides equilibrium search model of unemployment explains only about 10% of the response in the job-finding rate to an aggregate productivity shock. Some of the recent papers inspired by his critique are reviewed and commented on here. Specifically, we...

In a path-breaking but largely overlooked study, published in a festchrift thirty years ago (1975), Herman Van der Wee provided a comparison of prices and real wages of building craftsmen in the regions of Antwerp and south-eastern England, from 1400 to 1700. To do so, he constructed a composite...

I reconcile macro- and micro-evidence on price setting in a search and matching framework. Search frictions lead price-setting firms to negotiate wage rates with their employees. In contrast to the existing macro-labor literature, I assume that wage-bargaining and price-setting occur in the same...

This paper develops and solves a general equilibrium business cycle model with on-the-job search and wage rigidity arising from long-term labor contracts. Labor search models without these features have been criticized for failing to generate procyclical movements in job vacancies and...

After the presentation of the Phillips curve as an empirical regularity (Phillips 1958 ) economists and policy makers alike have tried to exploit it for policy purposes. Even before the oil shocks in the seventies and early eighties this has had mixed success only. With the advent of...
