Economic Crises and the Crisis of Economics

LONDON – Is the economics profession “in crisis”? Many policymakers, such as Andy Haldane, the Bank of England’s chief economist, believe that it is. Indeed, a decade ago, economists failed to see a massive storm on the horizon, until it culminated in the most destructive global financial crisis in nearly 80 years. More recently, they misjudged the immediate impact that the United Kingdom’s Brexit vote would have on its economy.

Of course, the post-Brexit forecasts may not be entirely wrong, but only if we look at the long-term impact of the Brexit vote. True, some economists expected the UK economy to collapse during the post-referendum panic, whereas economic activity proved to be rather resilient, with GDP growth reaching some 2.1% in 2016. But now that British Prime Minister Theresa May has implied that she prefers a “hard” Brexit, a gloomy long-term prognosis is probably correct.

Unfortunately, economists’ responsibility for the 2008 global financial crisis and the subsequent recession extends beyond forecasting mistakes. Many lent intellectual support to the excesses that precipitated it, and to the policy mistakes – particularly insistence on fiscal austerity and disregard for widening inequalities – that followed it.

Some economists have been led astray by intellectual arrogance: the belief that they can always explain real-world complexity. Others have become entangled in methodological issues – “mistaking beauty for truth,” as Paul Krugman once observed – or have placed too much faith in human rationality and market efficiency.
