Krugman and the “Long Depression” Myth

Recessions are common; depressions are rare. As far as I can tell, there were only two eras in economic history that were widely described as "depressions" at the time: the years of deflation and instability that followed the Panic of 1873 and the years of mass unemployment that followed the financial crisis of 1929-31.

Neither the Long Depression of the 19th century nor the Great Depression of the 20th was an era of nonstop decline -- on the contrary, both included periods when the economy grew. But these episodes of improvement were never enough to undo the damage from the initial slump, and were followed by relapses.

We are now, I fear, in the early stages of a third depression. It will probably look more like the Long Depression than the much more severe Great Depression. But the cost -- to the world economy and, above all, to the millions of lives blighted by the absence of jobs -- will nonetheless be immense.

Orthodox economic historians have long complained about the "great depression" that is supposed to have struck the United States in the panic of 1873 and lasted for an unprecedented six years, until 1879. Much of this stagnation is supposed to have been caused by a monetary contraction leading to the resumption of specie payments in 1879. Yet what sort of "depression" is it which saw an extraordinarily large expansion of industry, of railroads, of physical output, of net national product, or real per capita income? As Friedman and Schwartz admit, the decade from 1869 to 1879 saw a 3-percent-perannum increase in money national product, an outstanding real national product growth of 6.8 percent per year in this period, and a phenomenal rise of 4.5 percent per year in real product per capita. Even the alleged "monetary contraction" never took place, the money supply increasing by 2.7 percent per year in this period. From 1873 through 1878, before another spurt of monetary expansion, the total supply of bank money rose from $1.964 billion to $2.221 billion--a rise of 13.1 percent or 2.6 percent per year. In short, a modest but definite rise, and scarcely a contraction. It should be clear, then, that the "great depression" of the 1870s is merely a myth--a myth brought about by misinterpretation of the fact that prices in general fell sharply during the entire period. Indeed they fell from the end of the Civil War until 1879. Friedman and Schwartz estimated that prices in general fell from 1869 to 1879 by 3.8 percent per annum. Unfortunately, most historians and economists are conditioned to believe that steadily and sharply falling prices must result in depression: hence their amazement at the obvious prosperity and economic growth during this era. For they have overlooked the fact that in the natural course of events, when government and the banking system do not increase the money supply very rapidly, freemarket capitalism will result in an increase of production and economic growth so great as to swamp the increase of money supply. Prices will fall, and the consequences will be not depression or stagnation, but prosperity (since costs are falling, too) economic growth, and the spread of the increased living standard to all the consumers.
