Ep. 101: Views on the dollar shortage controversy

In the fifteen years following the end of World War II, Western Europe's capital account surpluses were not sufficient to finance its trade deficit with the United States. Charles Kindleberger of MIT, who helped assemble the Marshall Plan, defined this gap as the "dollar shortage" and argued that it was a structural problem rooted in Europe's lagging productivity, one that could only be fixed by sustained US lending. Milton Friedman disagreed, treating the shortage as a simple consequence of overvalued fixed exchange rates that floating currencies would correct. The argument continued through scores of books and articles written by many other economists into the late 1950s, until Europe's productivity caught up, and the debate faded. In a paper in the Journal of Economic Perspectives, authors Harris Dellas and George S. Tavlas revisit the controversy and explain why it still matters. They find that Kindleberger anticipated much of what is now called the intertemporal approach to the current account, and they trace how two recent episodes of dollar shortages echo and depart from the original.  Dellas and Tavlas recently spoke with Tyler Smith about the paper.
