We analyze a general search model with on-the-job search and sorting of heterogeneous workers into heterogeneous jobs. This model yields a simple relationship between (i) the unemployment rate, (ii) the value of non-market time, and (iii) the max-mean wage differential. The latter measure of...

An advantage of collective wage agreement is that search and business-stealing externalities can be internalized. A disadvantage is that it takes more time before an optimal allocation is reached because more productive firms (for a particular worker type) can no longer signal this by posting...

We build an analytically and computationally tractable stochastic equilibrium model of unemployment in heterogeneous labor markets. Facing search frictions within markets and reallocation frictions between markets, workers endogenously separate from employment and endogenously reallocate between...

We consider positive and normative aspects of subsidizing work arrangements where subsidies are paid in time of low demand and reduced working hours so as to stabilize workers’ income. In a matching framework such an arrangement increases labor demand. Tightening eligibility to short-time work...

In recessions, unemployment increases despite the - perhaps counterintuitive - fact that the number of unemployed workers finding jobs expands. On net, unemployment rises only because even more workers lose their jobs. We propose a theory of unemployment fluctuations resting on this...

Large and persistent earnings losses following displacement have adverse consequences for the individual worker and the macroeconomy. Leading models cannot explain their size and disagree on their sources. Two mean-reverting forces make earnings losses transitory in these models: search as an...

This paper presents a tractable dynamic general equilibrium model that can explain cross-country empirical regularities in geographical mobility, unemployment and labor market institutions. Rational agents vote over unemployment insurance (UI), taking the dynamic distortionary e.ects of...

This paper explores the impact of undocumented as opposed to documented immigration in a model featuring search frictions and non-random hiring that is consistent with novel empirical evidence presented. In this framework, undocumented immigrants’ wages are the lowest of all workers due to...

This paper studies the effect of coworker-based networks on individual labour market outcomes. I analyse how the provision of labour market relevant information by former coworkers affects the employment probabilities and, if hired, the wages of male workers who have previously become unemployed...
