Hoisington Q2 Letter

The three competing theories for economic contractions are: 1) the Keynesian, 2) the Friedmanite, and 3) the Fisherian. The Keynesian view is that normal economic contractions are caused by an insufficiency of aggregate demand (or total spending). This problem is to be solved by deficit spending. The Friedmanite view, one shared by our current Federal Reserve Chairman, is that protracted economic slumps are also caused by an insufficiency of aggregate demand, but are preventable or ameliorated by increasing the money stock. Both economic theories are consistent with the widely-held view that the economy experiences three to seven years of growth, followed by one to two years of decline. The slumps are worrisome, but not too daunting since two years lapse fairly quickly and then the economy is off to the races again. This normal business cycle framework has been the standard since World War II until now.

The Fisherian theory is that an excessive buildup of debt relative to GDP is the key factor in causing major contractions, as opposed to the typical business cycle slumps (Chart 1). Only a time consuming and difficult process of deleveraging corrects this economic circumstance. Symptoms of the excessive indebtedness are: weakness in aggregate demand; slow money growth; falling velocity; sustained underperformance of the labor markets; low levels of confidence; and possibly even a decline in the birth rate and household formation. In other words, the normal business cycle models of the Keynesian and Friedmanite theories are overwhelmed in such extreme, overindebted situations.

Economists are aware of Fisher’s views, but until the onset of the present economic circumstances they have been largely ignored, even though Friedman called Irving Fisher “America’s greatest economist.” Part of that oversight results from the fact that Fisher’s position was not spelled out in one complete work. The bulk of his ideas are reflected in an article and book written in 1933, but he made important revisions in a series of letters later written to FDR, which currently reside in the Presidential Library at Hyde Park. In 1933, Fisher held out some hope that fiscal policy might be helpful in dealing with excessive debt, but within several years he had completely rejected the Keynesian view. By 1940, Fisher had firmly stated to FDR in several letters that government spending of borrowed funds was counterproductive to stimulating economic growth. Significantly, by 2011, Fisher’s seven decade-old ideas have been supported by thorough, comprehensive and robust econometric and empirical analysis. It is now evident that the actions of monetary and fiscal authorities since 2008 have made economic conditions worse, just as Fisher suggested. In other words, we are painfully re-learning a lesson that a truly great economist gave us a road map to avoid.
