Reduced-form tests of scale effects in markets with search, run when aggregate matching functions are estimated, may miss important scale effects at the micro level, because of the reactions of job searchers. A semi-structural model is developed and estimated on a British sample, testing for...

This paper evaluates two theories of unemployment: the natural rate theory (whereby unemployment is depicted as fluctuating around a reasonably stable natural rate) and the chain reaction theory (which views movements in unemployment as the outcome of the interplay between labour market shocks...

This paper surveys recent work in equilibrium models of labor markets characterized by search and recruitment frictions and by the need to reallocate workers across productive activities. The duration of unemployment and jobs and wage determination are treated as endogenous outcomes of job...

This paper explores the optimal design of subsidies for hiring unemployed workers (‘employment vouchers’ for short) in the context of a simple macroeconomic model of the labour market. Focusing on the short-term and long-term effects of the vouchers on employment and unemployment, the...

The paper explores the employment implications of allowing people the opportunity of using a portion of their incapacity benefits to provide employment vouchers for employers that hire them. The analysis indicates that introducing this policy could increase employment, raise the incomes of...

Does capital-embodied technological change play an important role in shaping labour market inequalities? This Paper addresses the question in a model with vintage capital and search/matching frictions where costly capital investment leads to large heterogeneity in productivity among vacancies in...

We develop a simple model of short- and long-term unemployment to study how labour market institutions interact with labour market conditions and personal characteristics of the unemployed. We analyze how the decision to exit unemployment and to mitigate human capital degradation by retraining...

Recent research in macroeconomics emphasizes the role of wage rigidity in accounting for the volatility of unemployment fluctuations. We use worker-level data from the CPS to measure the sensitivity of wages of newly hired workers to changes in aggregate labor market conditions. The wage of new...

The paper examines the employment and unemployment implications of permitting unemployed people to use part of their unemployment benefits to provide employment vouchers to the firms that hire them. This opportunity to transfer unemployment benefits, `benefit transfers', would help replace the...

The Nash wage bargaining model is ubiquitous in modern labour economics. Yet most applications of this model ignore inter-employer competition for labour services and attribute all of the workers’ rent to their bargaining power. In this Paper, we write and estimate an equilibrium model with...
