A Dissection of Trading Capital: Trade in the Aftermath of the Fall of the Iron Curtain
研究了铁幕倒塌后欧洲贸易，发现前奥匈帝国国家间贸易远超标准引力模型预测，这种由哈布斯堡统治时期建立的文化贸易资本在分离四十年后仍起作用，但1990年后迅速消失。
We study trade in Europe after the fall of the Iron Curtain, and show that the countries of the former Austro-Hungarian monarchy trade significantly more with one another after 1989 than predicted by a standard gravity model. Cultural trading capital, established under Habsburg rule and maintained in the period of the Iron Curtain, seems to have survived over four decades of separation and gives an initial boost to trade. This surplus trade disappeared rapidly after 1990 as countries rearranged themselves with the new geopolitical circumstances. We document the rate of decay of these forces.
