LONDON – The tenth anniversary of the start of the Great Recession was the occasion for an elegant essay by the Nobel laureate economist Paul Krugman, who noted how little the debate about the causes and consequences of the crisis have changed over the last decade. Whereas the Great Depression of the 1930s produced Keynesian economics, and the stagflation of the 1970s produced Milton Friedman’s monetarism, the Great Recession has produced no similar intellectual shift.
This is deeply depressing to young students of economics, who hoped for a suitably challenging response from the profession. Why has there been none?
Krugman’s answer is typically ingenious: the old macroeconomics was, as the saying goes, “good enough for government work.” It prevented another Great Depression. So students should lock up their dreams and learn their lessons.
