The risk that the world’s investors currently are trying to avoid by rushing into US, Japanese, and German sovereign debt is not a “fundamental” risk.

BERKELEY – Four times in the past century, a large chunk of the industrial world has fallen into deep and long depressions characterized by persistent high unemployment: the United States in the 1930’s, industrialized Western Europe in the 1930’s, Western Europe again in the 1980’s, and Japan in the 1990’s. Two of these downturns – Western Europe in the 1980’s and Japan in the 1990’s – cast a long and dark shadow on future economic performance.
