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 develop a theory of interstate conflict in which the degree of genealogical relatedness between populations has a positive effect on their conflict propensities because more closely related populations, on average, tend to interact more and develop more disputes over sets of common issues. 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 measurement and estimation of the effects of...

What obstacles prevent the most productive technologies from spreading to less developed economies from the world’'s technological frontier? In this paper, we seek to shed light on this question by quantifying the geographic and human barriers to the transmission of technologies. We argue that...

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' last common ancestors, bears a statistically and economically significant...

This paper presents a framework to understand and measure the effects of political borders on economic growth and per capita income levels. In our model, political integration between two countries results in a positive country size effect and a negative effect through reduced openness...

A growing and deepening divide has opened up between countries where economic development has “taken off” and those caught in a vicious cycle of institutional backwardness and macroeconomic instability. This “Great Divide” is visible in almost every measure of economic performance, such...

This Paper analyses the transmission mechanisms of monetary policy in a general equilibrium model of securities markets and banking with asymmetric information. Banks' optimal asset/liability policy is such that in equilibrium capital adequacy constraints are always binding. Asymmetric...

In an environment characterized by weak contractual enforcement, sovereign lenders can enhance the likelihood of repayment by making their claims more difficult to restructure. We show within a simple model how competition for repayment between lenders may result in sovereign debt that is...

We analyze contagious sovereign debt crises in financially integrated economies. Under financial integration banks optimally diversify their holdings of sovereign debt in an effort to minimize the costs with respect to an individual country's sovereign debt default. While diversification...
