This paper constructs a theory of the coexistence of fixed-term and permanent employment contracts in an environment with ex-ante identical workers and employers. Workers under fixed-term contracts can be dismissed at no cost while permanent employees enjoy labor protection. In a labor market...

This paper presents a tractable model to explain the coexistence of temporary and permanent employment contracts. In our environment, workers are ex-ante heterogeneous and self-select into markets characterized by different labor contracts offered by firms. As a result, segmented labor markets...

This paper studies the impact of higher aggregate uncertainty on labor markets where jobs with strong employment protection coexist with temporary contracts. We develop a search and matching model where firms and workers choose the type of contract. The model allows for endogenous separations...

We study the cyclical dynamics of the value of a vacant position in labor markets characterized by search and matching frictions. We present a model of aggregate fluctuations in which firms face sunk costs to enter the production process. Our specification of sunk costs gives rise to a...

Over the business cycle, labor's share of output is negatively but weakly correlated with output, and it lags output by about four quarters. Profit's share is strongly procyclical. It neither leads nor lags output, and its volatility is about four times that of output. Despite the importance of...

This paper is concerned with the business cycle dynamics in search-and-matching models of the labor market when agents are ex post heterogeneous. We focus on wealth heterogeneity that comes as a result of imperfect opportunities to insure against idiosyncratic risk. We show that this...
