Chris Casey writes in today’s Mises Daily:
If deflation does not cause recessions (or depressions as they were known prior to World War II), what does? And why was it so prominently featured during the Great Depression? According to economists of the Austrian School of economics, recessions share the same source: artificial inflation of the money supply. The ensuing “malinvestment” caused by synthetically lowered interest rates is revealed when interest rates resort to their natural level as determined by the supply and demand of savings.
In the resultant recession, if fractional-reserve-based loans are defaulted or repaid, if a central bank contracts the money supply, and/or if the demand for money rises significantly, deflation may occur. More frequently, however, as central bankers frantically expand the money supply at the onset of a recession, inflation (or at least no deflation) will be experienced. So deflation, a sometime symptom, has been unjustly maligned as a recessionary source.
