B. Eichengreen et Da. Irwin, TRADE BLOCS, CURRENCY BLOCS AND THE REORIENTATION OF WORLD-TRADE IN THE 1930S, Journal of international economics, 38(1-2), 1995, pp. 1-24
We analyze the impact of commercial and financial policies on the reor
ientation of trade in the 1930s. We report evidence that commercial po
licies attenuated prior connections between income growth and trade, a
nd that exchange rate instability marginally discouraged international
trade. In contrast, the tendency toward regionalization commonly ascr
ibed to the formation of trade and currency blocs was already evident
to a considerable extent prior to the regional policy initiatives of t
he 1930s. This reorientation is more properly attributed to ongoing hi
storical forces such as commercial and financial links between countri
es forged over many years.
