How valuable are cognitive and social abilities for entrepreneurs’ incomes as compared to employees? We answer three questions: (1) To what extent does a composite measure of ability affect an entrepreneur's earnings relative to employees? (2) Do different cognitive abilities (e.g. math...

We study optimal linear income taxation in a model with heterogeneous agents where earnings potentials are endogenously determined through human capital accumulation. Agents differ in initial conditions and ability to learn. Capital market imperfections prevent poor agents to invest optimally in...

In this paper we study the allocation of workers over high and low productivity firms in a labor market with coordination frictions. Specifically, we consider a search model where workers can apply to high and or low productivity firms. Firms that compete for the same candidate can increase...

This paper examines the effect of differences in ability on the timing and number ofchildren. Higher skilled women have less disutility of labor and have relatively lessutility of raising children. Motherhood has a negative effect on the accumulation ofhuman capital by learning-by-doing and...

Parker and Van Praag (2009) showed, based on theory, that the group status of the profession ‘entrepreneurship’ shapes people’s occupational preferences and thus their choice behavior. The current study focuses on the determinants and consequences of the group status of a profession,...

This paper has resulted in a publication in <I>Labour Economics</I> (2013), 23, 50-56.<P> The paper provides a theoretical foundation for the empirical regularities observed in estimations of wage consequences of overeducation and undereducation. Workers with more education than required for their jobs...</p></i>

Nobel laureates in economics make their most important and creative contributionsbetween the ages of 29 and 38. The average creative age of Nobel economists is slightly belowthat of laureates in physics, and considerably younger than that of laureates in chemistry andmedicine/physiology. The...

When verifiable performance measures are imperfect, organizations often resort to subjective performance pay. This may give supervisors the power to direct employees towards tasks that mainly benefit the supervisor rather than the organization. We cast a principal-supervisor-agent model in a...

In the Netherlands auditors can be trained in a part-time educational track in which students combine working and studying or in a full-time educational track. The former training is relatively firm-specific whereas the latter training is relatively general. Applying human capital theory, we...

Understanding of the substantial disparity in health between low and high socioeconomic status (SES) groups is hampered by the lack of a suffciently comprehensive theoretical framework to interpret empirical facts and to predict yet untested relations. We present a life-cycle model that...
