We show that the countries of the former Austro-Hungarian monarchy trade significantly more with one another in the aftermath of the collapse of the Iron Curtain than predicted by a standard gravity model.  This trade surplus declines linearly and monotonically over time.  We argue that these...

This paper studies the distributional impact of commodity price shocks over both the short and very long run.  Using a GARCH model, we find that Australia experienced more volatility than many commodity exporting developing countries over the periods 1865-1940 and 1960-2007.  A single equation...

Gravity equations in trade imply that trade flows are proportional to the size of a country and inversely proportional to distance.  This paper develops an analogy of these observations with gravity in physics, and provides geometric intuition for a large class of mathematical processes in two...
