Parenthood and Productivity of Highly Skilled Labor: Evidence from the Groves of Academe

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 productivity. Nor do we find a statistically significant unconditional effect of a first child on research productivity. Conditional difference-in-differences estimates, however, suggest that the effect of parenthood on research productivity is negative for unmarried women and positive for untenured men. Moreover, becoming a mother before 30 years of age appears to have a detrimental effect on research productivity

Lobbying and Political Polarization

Standard spatial models of political competition give rise to equilibria in which the competing political parties or candidates converge to a common position. In this paper I show how political polarization can be generated in models that focus on the nexus between pre-election interest group lobbying and electoral competition

Schneewittchen im Land der Klapperschlangen: Evaluation eines Evaluators

This is a comment on a ranking of German economics departments published by a semi-official institution, the Center for Higher Education Development (CHE). It is shown that the CHE ranking is highly misleading because the publication output is not weighted according to quality. The CHE ranking is compared to the results of four recent ranking studies commissioned by the European Economic Association (EEA) and an earlier ranking of German, Austrian and Swiss economics departments. For the readers from Austria and Switzerland we include in the appendix a 'sneak preview' of the 'EEA rankings' which includes the top-ranked Austrian and Swiss departments.

Globalization and Gender Equality in Developing Countries

This study empirically assesses the influence of globalization on the institutional root causes of gender equality as measured by the new OECD Social Institutions and Gender Index (SIGI). We capture the multifaceted concept of globalization with the KOF index and its three sub-indices which measure the economic, social and political dimensions of globalization. Observing the progress of globalization for a sample of almost one hundred countries at ten year intervals starting in 1970, we find that economic and social globalization exerted a decidedly positive influence on the social institutions which underlie gender equality
