This paper conducts a cross-national econometric analysis of intra-family location and caregiving patterns. First, we assess, from an international perspective, the relationship between family structure and the geographic proximity between adult children and their parents. We then examine...

We study the persistence of the gender unemployment gap in the Italian regions in the 1992-2009 period. Results from unit-root tests analysis with structural break suggest that the process of gender catching-up in the unemployment rates is occurring in most of the regions but at different pace....

Cooperativeness among genetically unrelated humans remains a major puzzle in the social sciences. We explore the causal impact of physical distance on willingness to help. In a field setting, participants decide about supporting local refugees at the dispense of money to themselves. We vary...

We review and interpret the main theoretical developments in the gravity literature from its very early, a-theoretical applications to the latest structural contributions. We also discuss challenges and implement methods to estimate empirical gravity equations. We finish with a presentation and...

This paper looks at the effect of the relatedness of two countries, measured by their genetic distance, on educational migrant selection. We analyze bilateral country-level education-specific migration stocks from 85 sending countries to the 15 main destination countries in 2000 and show that...

The effects of ethnic geography, i.e., the distribution of ethnic groups across space, on economic, political and social outcomes are not well understood. We develop a novel index of ethnic segregation that takes both ethnic and spatial distances between individuals into account. Importantly, we...

Using a novel common econometric specification, we examine the measurement of three important effects in international trade that historically have been addressed largely separately: the (partial) effects on trade of economic integration agreements, national borders, and bilateral distance....

We use the recent introduction of tuition fees at public universities in seven of the sixteen German states to identify the effects of tuition fees on university enrollment of first-year students at German public universities. Our study differs from previous research in two important ways....
