The introduction of firm size into labor search models raises the question how wages are set when average and marginal product differ. We develop and analyze an alternative to the existing bargaining framework: Firms compete for labor by publicly posting long- term contracts. In such a...

The paper develops an equilibrium search and matching model where two-person families as well as singles participate in the labor market. We show that equilibrium entails wage dispersion among equally productive risk-averse workers. Marital status as well as spousal labor market status matter...

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 develop and estimate a non-stationary job search model to evaluate a scheme that monitors job search effort and sanctions insured unemployed whose effort is deemed insufficient. The model reveals that such schemes provide incentives to the unemployed to front-load search effort prior to...

This paper studies optimal unemployment benefit levels and optimal proportional income tax rates over the business cycle. Previous research suggests that policy makers should make unemployment insurance (UI) dependent on the business cycle because the UI system can be used to smooth consumption...

A significant fraction of the labor force consists of employed workers who are part-time unemployed (underemployed) in the sense that they are unable to work as much as they prefer. This paper develops a search and matching model to study the design of optimal unemployment insurance in an...

We introduce different skill groups and production functions into the Burdett-Mortensen equilibrium search model. Supermodularity in the production process leads to a positive intrafirm wage correlation between skill groups. Theory implies that increasing returns to scale can lead to a unimodal...

This paper analyzes an urn-ball matching model in which workers decide how intensively they sample job openings and apply at a stochastic number of suitable vacancies. Equilibrium is not constrained efficient; entry is excessive and search intensity can be too high or too low. Moreover, an...

We analyze the following question associated with flexible outsourcing under imperfect domestic labour market: How does the implementation of profit sharing influence flexible outsourcing? We show that in general profit sharing has a negative effect on low skilled wage and thus an outsourcing...

We combine profit sharing and outsourcing, if the wage for worker is decided by a labor union to analyze how does the implementation of profit sharing affect individual effort and the bargained wage and thus outsourcing? We find that profit sharing and the wage level have an individual...
