Many experts claim that the incidence of suicide attacks is driven by religious cleavages. To test this hypothesis, we investigate whether the total number of suicide attacks per violent conflict or the annual number of suicide attacks per country is associated with simmering religious...

Using a representative survey of German university students, we confirm that proclaimed support for environment protection policies depends on socio-cultural factors and political ideology. Unlike most related studies for other countries, we find that the environmental policy stance of German...

We investigate whether the field of study influences university students' political attitudes. To disentangle self-selection from learning effects, we first investigate whether the fields of study chosen by the incoming students correlate with their political attitudes. In a second step we...

I model the strategic interaction between scientists aiming for promotion and a research institution that seeks a highly productive faculty by setting a maternity allowance in the form of a minimum promotion standard. The model shows that maternity allowances need not derive from moral justice...

We provide a measure of equality of educational opportunity in 54 countries, estimated as the effect of family background on student performance in two international TIMSS tests. We then show how organizational features of the education system affect equality of educational opportunity. Our...

We study the effects of random assignment to coeducational and single-sex classes on the academic performance of female high school students. Our estimation results show that single-sex schooling improves the performance of female students in mathematics. This positive effect increases if the...

We examine the effect of pregnancy and parenthood on the research productivity of academic economists. Combining the survey responses of nearly 10,000 economists with their publication records as documented in their RePEc accounts, we do not find that motherhood is associated with low research...

In this paper we ague that any meaningful bibliometric evaluation of researchers needs to take into account that research productivity follows distinct life cycles. Using an encompassing data set portraying the research behavior of German academic economists, we first show that research...
