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...

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...

This paper explores the impact of undocumented as opposed to documented immigration in a model featuring search frictions and non-random hiring that is consistent with novel empirical evidence presented. In this framework, undocumented immigrants' wages are the lowest of all workers due to their...

This paper investigates empirically the role of taxes on labor for the stock of expatriates and the migration flows of skilled workers. Given the increasing mobility of labour, especially of high-skilled people and expatriates, it is interesting to see to what extent labour income taxes and...

Tax competition between two governments who choose nonlinear income tax schedules to maximize the average utility of its residents when skills are unobservable and labor is perfectly mobile is examined. We show that there are no Nash equilibria in which there is a skill type that pays positive...

This paper analyzes how integrated labor markets affect the financing of higher education. For this, we employ a general-equilibrium model with overlapping generations and individuals who differ in their abilities. At the first stage, governments can choose the quality of education and the...

The global distribution of talent is highly skewed and the resources available to countries to develop and utilize their best and brightest vary substantially. The migration of skilled workers across countries tilts the deck even further. Using newly available data, we first review the landscape...

We develop a model to explain two-way migration of high-skilled individuals between countries that are similar in their economic characteristics. High-skilled migration results from the combination of workers whose abilities are private knowledge, and a production technology that gives...

We study the interaction between the optimal immigration policy of a host country and education policy of a source country in a model of international migration of skilled workers. Acquisition of human capital is driven by the academic and career opportunities at home and abroad. Greater...
