Why are some societies still poor? Recent research suggests that a country’s “genetic distance”—a measure of the time elapsed since two populations had common ancestry—from the United States is a significant predictor of development even after controlling for an ostensibly exhaustive...

Why are some peoples still poor? Recent research suggests the possibility that some societies may be poor due to their genetic endowments, which are found to be a significant predictor of development even after controlling for an ostensibly exhaustive list of geographic and cultural variables....

The massive stocks of foreign exchange reserves, mostly held in the form of U.S. T-Bonds by emerging economies, are still an important puzzle. Why do emerging economies continue to willingly loan to the United States despite the low rates of return? We propose that a dynamic general equilibrium...

Not only are investors biased toward home assets, but when they do invest abroad, they appear to favor countries with returns more correlated with home assets. Often attributed to a preference for familiarity, this ‘correlation puzzle’ further reduces effective diversification. However, a...

We investigate the effect of trade integration on interstate military conflict. Our empirical analysis, based on a large panel data set of 243,225 country-pair observations from 1950 to 2000, confirms that an increase in bilateral trade interdependence significantly promotes peace. It also...

Commonly used trade-weighted real exchange rate indices are computed as indices-of-indices, and thus do not adequately account for growth in trade with developing countries. Weighted Average Relative Price (WARP) indices solve this problem but do not control for productivity differences, as...

Does leaving a currency union reduce international trade? This paper reexamines time series estimates of currency unions on trade from a historical perspective using a dynamic gravity equation and by conducting in-depth case studies of currency union breakups. The early large estimates are...
