In this paper, I study the wage a firm sets to attract high abilityworkers (hipo's) in situationsof unemployment. I show that the higher unemployment, the larger afirm's incentives to sorthigh and low ability workers. Moreover, workers will signal their(high) ability in situationsof (high)...

Often, the effect is predicted to be negative. Despite the popularity of these...</p></a>

This paper develops a model in which workers are heterogeneous in their intrinsic motivation to work at a firm. We characterise optimal incentive schemes and examine how the firm can attract and select highly motivated workers to fill a vacancy when workers’ motivation is private information....

I consider a situation in which heterogenous senders (applicants) compete in order to be selected by one receiver (employer). Productivity is private information to the senders, and the receiver processes imperfect signals (applications) to screen among applicants. The information-processing...

We investigate an equilibrium search model in which the search frictions are increasing with the distance to the central business district allowing for on-the-job search and endogenous (monopsony) wage formation and land allocation. We find that there are many different possible outcomes with...

In the labor market, statistical discrimination occurs when employers' beliefs about workers' behavior induce different groups of workers to invest at different rates in their education. Thus, even though groups may be identical ex-ante, the beliefs of the employers are self-fulfilling....

This paper offers a new theory of discrimination in the workplace. We consider a manager who has to assign two tasks to two employees. The manager has superior information about the employees' abilities. We show that besides an equilibrium where the manager does not discriminate, equilibria...

In this paper, we use quantile regression decomposition methods to analyzethe gender gap between men and women who work full time in the Nether-lands. Because the fraction of women working full time in the Netherlands isquite low, sample selection is a serious issue. In addition to shedding...

This paper presents a unified theory of human capital with both health capital and, what we term, skill capital endogenously determined within the model. By considering joint investment in health capital and in skill capital, the model highlights similarities and differences in these two...
