Joseph Salerno writes in today’s Mises Daily:
Brown explains that such monetary disequilibrium is not necessarily manifested in consumer price inflation in the short run. In fact, it is generally the case that the symptoms first appear as rising temperatures on assets markets. Indeed some episodes of severe monetary disequilibrium, such as those that occurred in the U.S. during the 1920s, the 1990s, and the years leading up to the financial crisis of 2007-2008, may well transpire without any discernible perturbations in goods and services markets. Yet overheated asset markets are completely ignored in the Friedmanite view of monetary equilibrium that underlies the Bernanke-Draghi policy of inflation targeting. Brown perceptively argues that one reason for the wholesale neglect of asset price inflation is the positivist approach that is still dominant in academic economics. Speculative fever in asset markets is nearly impossible to quantify or measure and thus does not neatly fit into the kinds of hypotheses that are required for empirical testing.
