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...

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...

The impacts of introducing or tightening time limits on welfare use are studied in an efficiency wage model. Those losing access to regular benefits receive some smaller benefit, which can be interpreted as food stamps. Stricter time limits raise both employment and profits and generally reduce...

The impact of a stronger work requirement for welfare recipients in a workfare program is studied in an efficiency wage model where a representative firm chooses its level of monitoring activities. A stricter workfare policy raises employment and monitoring activities. It typically increases...

This paper investigates the role that idiosyncratic uncertainty plays in shaping social preferences over the degree of labor market flexibility, in a general equilibrium model of dynamic labor demand where the productivity of firms evolves over time as a Geometric Brownian motion...

This paper investigates the effects of organizational and technological changes on jobstability of different occupational categories in France. We conduct an empirical analysis inwhich we make extensive use of a unique data set on a representative sample of Frenchestablishments...

This study documents two empirical regularities, using data for Denmark and Portugal. First, workers who are hired last, are the first to leave the firm (Last In, First Out; LIFO). Second, workers’ wages rise with seniority (= a worker’s tenure relative to the tenure of her colleagues). We...

This paper presents a case study on reforming a very dysfunctional labor market with a deep insider-outsider divide, namely the Spanish case. We show how a dual market, with permanent and temporary employees makes real reform much harder, and leads to purely marginal changes that do not alter...

This paper analyzes the strikingly different response of unemployment to the Great Recession in France and Spain. Their labor market institutions are similar and their unemployment rates just before the crisis were both around 8%. Yet, in France, unemployment rate has increased by 2 percentage...

Using a linked employer-employee dataset and taking the perspective of individuals rather than firms, this paper analyzes some effects of joining start-ups. We show that entrants in new firms differ from those joining incumbent firms, and we use a matching approach to compare a group of...
