Governments must beware the lure of free money

Budget constraints have gone missing. That presents both danger and opportunity

It is sometimes said that governments wasted the global financial crisis of 2007-09 by failing to rethink economic policy after the dust settled. Nobody will say the same about the covid-19 pandemic. It has led to a desperate scramble to enact policies that only a few months ago were either unimaginable or heretical. A profound shift is now taking place in economics as a result, of the sort that happens only once in a generation. Much as in the 1970s when clubby Keynesianism gave way to Milton Friedman’s austere monetarism, and in the 1990s when central banks were given their independence, so the pandemic marks the start of a new era. Its overriding preoccupation will be exploiting the opportunities and containing the enormous risks that stem from a supersized level of state intervention in the economy and financial markets.
