Under symmetric information, a job protection law that says that a principal who has hired an agent today must also employ them tomorrow can only reduce the two parties’ total surplus. The law restricts the principal’s possibilities to maximize their profit, which equals the total surplus,...

A new methodology is described which tests between various equilibrium theories of unemployment using matching data. The Paper shows how to correct econometrically for temporal aggregation effects, where the econometrician’s aim is to identify a matching process using data which is recorded...

Unlike many other contracts, employment contracts are subject to various external administrative procedures governing separations, ranging from compulsory severance payments and advance notice periods (usually seniority based), to collective layoff procedures (usually depending on the firm's...

Hierarchies allow individuals to leverage their knowledge through others' time. This mechanism increases productivity and amplifies the impact of skill heterogeneity on earnings inequality. To quantify this effect, we analyze the earnings and organization of U.S. lawyers and use the equilibrium...

Employment protection systems are known to generate significant distortions in firms’ hiring and firing decisions. We know much less about the impact of these regulations on workers behaviour. The goal of this Paper is to fill in this gap and in particular to assess whether the provision of...

Employment protection is often related to costs incurred by firms when they fire a worker. The stability of the employment relationship, enhanced by employment protection, is also favourable to the productivity of the job. We analyse employment protection focusing on this trade-off between...

Societies are characterized by customs governing the allocation of non-market goods such as marital partnerships. We explore how such customs affect the educational investment decisions of young singles and the subsequent joint labour supply decisions of partnered couples. We consider two...

This Paper examines the role of employment protection when firms learn over time about the value of the match. When parties can commit to future wages, equilibrium contracts stipulate positive severance payments as an instrument to induce efficient lay-off decisions and there is no room for...

This Paper considers a matching model of heterogeneous workers and jobs, which includes on-the-job search. High-educated workers transitorily accept unskilled jobs and continue to search for skilled jobs. We study the implications of this model for the unemployment rates of high and low-educated...

We show in the framework of a new economic geography model that when labour is heterogenous and productivity depends on the quality of the match between job and worker, trade liberalization may lead to industrial agglomeration and inter-industry trade. The agglomeration force is the improvement...
