We investigate the origin and evolution of the legal institution of citizenship from a political economy perspective. We compile a new data set on citizenship laws across countries of the world which documents how these institutions have evolved in the postwar period. We show that, despite a...

By means of a descriptive survey of theoretical literature we first work out the potential determinants that may drive international migration from developing to developed countries. In addition, we look at the relationship between trade, development and migration. Empirical studies focusing on...

OECD governments note rising immigration with alarm and grapple with policies aimed at selecting certain migrants and keeping out others. Economists appear to be well armed to advise governments since they are responsible for an impressive literature that examines the characteristics of...

Can international migration promote better institutions at home by raising the demand for political accountability? In order to examine this question, we designed a behavioral measure of the population’s desire for better governance. A postcard was distributed to households with the pledge...

We study the relationship between geography and growth. To do so, we first develop a dynamic spatial growth theory with realistic geography. We characterize the model and its balanced growth path and propose a methodology to analyze equilibria with different levels of migration frictions. We...

How has wellbeing evolved over time and across regions? How does the West compare to the Rest? What explains their differences? These questions are addressed using an historical index of human development. A sustained improvement in wellbeing has taken place since 1870. The absolute gap between...

In 1984, the world was shocked at the scale of a famine in Ethiopia that caused over half a million deaths, making it one of the worst in recent history. The mortality impacts are clearly signicant. But what of the survivors? This paper provides the first estimates the long-term impact of the...

Long-run trends in Africa’s well-being are provided on the basis of a new index of human development, alternative to the UNDP’s HDI. A sustained improvement in African human development is found that falls, nonetheless, short of those experienced in other developing regions. Within Africa,...
