What Good Are Economists?
NEW HAVEN – Since the global financial crisis and recession of 2007-2009, criticism of the economics profession has intensified. The failure of all but a few professional economists to forecast the episode – the aftereffects of which still linger – has led many to question whether the economics profession contributes anything significant to society. If they were unable to foresee something so important to people’s wellbeing, what good are they?
Indeed, economists failed to forecast most of the major crises in the last century, including the severe 1920-21 slump, the 1980-82 back-to-back recessions, and the worst of them all, the Great Depression after the 1929 stock-market crash. In searching news archives for the year before the start of these recessions, I found virtually no warning from economists of a severe crisis ahead. Instead, newspapers emphasized the views of business executives or politicians, who tended to be very optimistic.
The closest thing to a real warning came before the 1980-82 downturn. In 1979, Federal Reserve Chair Paul A. Volcker told the Joint Economic Committee of the US Congress that the United States faced “unpleasant economic circumstances,” and had a “need for hard decisions, for restraint, and even for sacrifice.” The likelihood that the Fed would have to take drastic steps to curb galloping inflation, together with the effects of the 1979 oil crisis, made a serious recession quite likely.
