In a world of trade restrictions, large countries enjoy economic benefits, because political boundaries determine the size of the market. Under free trade and global markets even relatively small cultural, linguistic or ethnic groups can benefit from forming small, homogeneous political...

Trade liberalization and political separatism go hand in hand. In a world of trade restrictions, large countries enjoy economic benefits because political boundaries determine the size of the market. In a world of free trade and global markets even relatively small cultural, linguistic or ethnic...

Normally, economists take the size of countries as an exogenous variable which does need to be explained. Nevertheless, the borders of countries and therefore their size change, partially in response to economic factors such as the pattern of international trade. Conversely, the size of...

In a world of trade restrictions, large countries enjoy economic benefits, because political boundaries determine the size of the market. Under free trade and global markets even relatively small cultural, linguistic or ethnic groups can benefit from forming small, homogeneous political...

In this chapter we argue that the endogenous growth model with quality-improving innovations provides a framework for analyzing the determinants of long-run growth and convergence that is versatile, simple and empirically useful. Versatile, as the same framework can be used to analyze how growth...

This paper studies the barriers to the diffusion of development across countries over the very long-run. We find that genetic distance, a measure associated with the amount of time elapsed since two populations%u2019 last common ancestors, bears a statistically and economically significant...

We find that genetic distance, a measure associated with the time elapsed since two populations' last common ancestors, has a statistically and economically significant effect on income differences across countries, even controlling for measures of geographical distance, climatic differences,...

We document an empirical relationship between the cross-country adoption of technologies and the degree of long-term historical relatedness between human populations. Historical relatedness is measured using genetic distance, a measure of the time since two populations' last common ancestors. We...

The empirical literature on economic growth and development has moved from the study of proximate determinants to the analysis of ever deeper, more fundamental factors, rooted in long-term history. A growing body of new empirical work focuses on the measurment and estimation of the effects of...
