What has driven trade booms and trade busts in the past and present? We derive a micro-founded measure of trade frictions from leading trade theories and use it to gauge the importance of bilateral trade costs in determining international trade flows. We construct a new balanced sample of...

This paper presents a new model of oligopoly in general equilibrium and explores its implications for positive and normative aspects of international trade. Assuming “continuum-Pollak” preferences, the model allows for consistent aggregation over a continuum of sectors, in each of which a...

We examine Chinese-US trade flows over the 1994-2012 period, and find that, in line with the conventional wisdom, the value of China's exports to the US responds negatively to real renminbi (RMB) appreciation, while import responds positively. Further, the combined empirical price effects on...

The medieval Champagne fairs are widely used to draw lessons about the institutional basis for long-distance impersonal exchange. This paper re-examines the causes of the outstanding success of the Champagne fairs in mediating international trade, the timing and causes of the fairs' decline, and...

We present new data documenting medieval Europe's “Commercial Revolution” using information on the establishment of markets in Germany. We use these data to test whether medieval universities played a causal role in expanding economic activity, examining the foundation of Germany's first...

Economists draw important lessons for modern development from the medieval Maghribi traders who, according to Greif, enforced contracts multilaterally through a closed, private-order 'coalition'. We show that this view is untenable. The Maghribis used formal legal mechanisms and entered business...

A large literature on "border effects" in the wake of McCallum (1995) documents the massive impact of borders on trade. However, all these studies suffer from an identification problem. "Border effects" are usually identified from cross-sectional variation alone. We do not know how trade would...

Rational choice theories of electoral participation stress that an individual's decision to vote depends on her expected net benefit from doing so. If this instrumental motive is relevant, then turnout should be higher in elections where more is at stake. We test this prediction, by studying how...
