We consider a model of on-the-job search where firms offer long-term wage contracts to workers of different ability. Firms do not observe worker ability upon hiring but learn it gradually over time. With sufficiently strong information frictions, low-wage firms offer separating contracts and...

The impact of the Covid-19 pandemic on the UK labour market has been extremely heterogeneous across occupation and industrial sectors. Using novel data on job search, we document how individuals adjust their job search behaviour in response to changing employment patterns across occupations and...

This paper studies the employment and reallocation effects of minimum wages in Germany in a search-and-matching model with endogenous job search effort and vacancy posting, multiple employment levels, a progressive tax-transfer system, and worker and firm heterogeneity. I find that minimum wages...

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...

The objective of this paper is to construct and quantitatively assess an equilibrium search model with on-the-job search and general human capital accumulation. In the model workers enter the labour market with different abilities and firms differ in their productivities. Wages are dispersed...

In this paper we investigate the incentives of unemployed workers to wait for a recall when recall probabilities are endogenously determined by the waiting decisions of others. Because of a positive externality that arises when workers seek new employment, an excessive number of workers choose...

We investigate a prevalent, but understudied, employment protection policy: mandatory advance notice (MN), requiring employers to notify employees of forthcoming layoffs. MN increases future production, as notified workers search on the job, but reduces current production as they supply less...

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 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 their...
