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...

In the standard macroeconomic search and matching model of the labor market, there is a tight link between the quantitative effects of (i) aggregate productivity shocks on unemployment and (ii) unemployment benefits on unemployment. This tight link is at odds with the empirical literature. We...

This paper tests whether aggregate matching is consistent with unemployment being mainly due to search frictions or due to job queues. Using U.K. data and correcting for temporal aggregation bias, estimates of the random matching function are consistent with previous work in this field, but...

This paper studies the effects of firing taxes on the job destruction rate, when probationperiod - or temporary contract - policies are implemented in an otherwise exogenous jobseparation search model. It is shown that contrary to conventional wisdom, firing taxescan amplify the job turnover...

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...

I study the cyclical behavior of an equilibrium search model with endogenous job creation and destruction, with focus on the model's failure to match the observed cyclical volatility of unemployment. Job creation in the model is influenced by wages in new matches. I summarize microeconometric...

It is increasingly recognized that labour markets are pervasively imperfectly competitive, that there are rents to the employment relationship for both worker and employer. This chapter considers why it is sensible to think of labour markets as imperfectly competitive, reviews estimates on the...

The Austrian Beveridge curve shifted in 2014, leading to ongoing academic discussions about the reasons behind this shift. While some have argued that the shift was caused by a supply shock due to labour market liberalization, others have stated that matching efficiency decreased. Using a new...

Does the search and matching model fit aggregate U.S. labor market data? While the model has become an important tool of macroeconomic analysis, recent literature pointed to some failures in accounting for the data. This paper aims to answer two questions: (i) Does the model fit the data, and,...

This paper studies the role of labor market institutions on unemployment and on the cyclical properties of job flows. We construct an intertemporal general equilibrium model with search unemployment and endogenous job turnover, and examine the consequences of introducing an unemployment benefit,...
