Previous research shows ethnic minority students to receive different grades when taught by majority teachers. This may happen either because of bias in teachers' grading, or because objective student performance is indeed altered. Using an experiment, I examine whether teachers grade minority...

This study reports a meta-analysis on the effects of ethnic minority share in school on achievement test scores. Best evidence from the studies that have appeared thus far on this topic shows that these compositional effects appear small in general, but may be larger when the ethnic minority...

Recent studies for primary and secondary education find positive effects of the share of girls in the classroom on achievement of boys and girls. This study examines whether these results can be extrapolated to post-secondary education. We conduct an experiment in which the shares of girls in...

The growing importance attached to education as a key factor to improve economic performance coupled with the persistent scarcity of resources for education makes it important that skills and literacy are produced efficiently. This paper provides an international comparison of the efficiency of...

We examine the work timing behavior of spouses. With work timing we mean the behavior that results in the performance of paid labor at the same time, that cannot be explained by factors other than the partners' potential to communicate on the timing of their work. We find that couples with...

Practitioners assess performance of entities in increasingly large and complicated datasets. If non-parametric models, such as Data Envelopment Analysis, were ever considered as simple push-button technologies, this is impossible when many variables are available or when data have to be compiled...

Although there is a common believe that better teachers produce better students, there is no unambiguous scientific evidence that teacher characteristics are causally related to student performance. This raises the question whether the things that teachers do in class are more important than the...

We estimate a collective time allocation model, where two-earner households behave as if the spouses maximize a household utility function, and where one-earner households, where only the man works, behave as if the spouses maximize a household utility function, conditional on the zero job-hour...

In this study we examine the collective labor supply choices of dual-earner parents and take into account child care expenditures. We find that the individual labor supplies are hardly affected by changes in the prices of child care services. In addition, the child care price effects on the...

In case of regional discretionary on the implementation of policy measures, central govern­ments may consider the differences in outcomes as an indication on the effectiveness of policy. In turn, to motivate regional policy makers uniform incentives might be developed. However, if the...
