Exploiting a novel geo-referenced data set of population diversity across ethnic groups, this research advances the hypothesis and empirically establishes that variation in population diversity across human societies, as determined in the course of the exodus of human from Africa tens of...

We investigate externalities in higher education enrollment over the course of development in a two-sector model. Each sector works with only one type of labor, skilled or unskilled, and individuals are differentiated according to their cost of acquiring human capital. Both sectors exhibit...

We use a change in Iceland’s education system as a natural experiment to measure the effect of years spent in upper secondary school on subsequent first year outcomes at university. The duration of Iceland´s upper-secondary education was shortened by one year through compression of the...

We undertake a trade-growth accounting exercise by decomposing data on changes in bilateral international trade flows into their direct (endowment accumulation, productivity growth, changes in trade costs, changing preferences) and indirect components (general equilibrium effects). Furthermore,...
