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...

We show how small initial wealth differences between low skilled black and white workers can generate large differences in their labour-market outcomes. This even occurs in the absence of a taste for discrimination against blacks or exogenous differences in the distance to jobs. Because of the...

Randomized experiments provide policy relevant treatment effects if there are no spillovers between participants and nonparticipants. We show that this assumption is violated for a Danish activation program for unemployed workers. Using a difference-in-difference model we show that the...

With the emergence of the Great Recession unemployment insurance (UI) is once again at the heart of the policy debate. In this paper, we review the recent theoretical and empirical evidence on the labor market effects of UI design. We also discuss policy issues related to UI design, including...

This Paper estimates the structural parameters of a job search model with hyperbolic discounting and endogenous search effort. It estimates quantitatively the degree of hyperbolic discounting, and assesses its implications for the impact of various policy interventions aimed at reducing...

This Paper exploits area-based piloting and age-related eligibility rules to identify treatment effects of a labour market program – the New Deal for Young People in the UK. A central focus is on substitution/displacement effects and on equilibrium wage effects. The programme includes...

Individual labour earnings observed in worker panel data have complex, highly persistent dynamics. We investigate the capacity of a structural job search model with i.i.d. productivity shocks to replicate salient properties of these dynamics, such as the covariance structure of earnings, the...

We assess the information spillovers generated by the exchange of job-related information within networks of fellow workers exploiting administrative records covering all employment relationships established in a specific local labor market over 20 years. We recover individual-specific networks...

We survey the recent literature on the effects of active labour market policies on individual labour market outcomes like employment and income, for adult female individuals without work in European countries. We consider skill-training programs, monitoring and sanctions, job search assistance,...
