John Maynard Keynes Is the Economist the World Needs Now

Is there a doctor in the house? The global economy is failing to thrive, and its caretakers are fumbling. Greece took its medicine as instructed and was rewarded with an unemployment rate of 26 percent. Portugal obeyed the budget rules; its citizens are looking for jobs in Angola and Mozambique because there are so few at home. Germans are feeling anemic despite their massive trade surplus. In the U.S., the income of a median household adjusted for inflation is 3 percent lower than at the worst point of the 2007-09 recession, according to Sentier Research. Whatever medicine is being doled out isn’t working. Citigroup (C) Chief Economist Willem Buiter recently described the Bank of England’s policy as “an intellectual potpourri of factoids, partial theories, empirical regularities without firm theoretical foundations, hunches, intuitions, and half-developed insights.” And that, he said, is better than things countries are trying elsewhere.

There is a doctor in the house, and his prescriptions are more relevant than ever. True, he’s been dead since 1946. But even in the past tense, the British economist, investor, and civil servant John Maynard Keynes has more to teach us about how to save the global economy than an army of modern Ph.D.s equipped with models of dynamic stochastic general equilibrium. The symptoms of the Great Depression that he correctly diagnosed are back, though fortunately on a smaller scale: chronic unemployment, deflation, currency wars, and beggar-thy-neighbor economic policies.

An essential and enduring insight of Keynes is that what works for a single family in hard times will not work for the global economy. One family whose breadwinner loses a job can and should cut back on spending to make ends meet. But everyone can’t do it at once when there’s generalized weakness because one person’s spending is another’s income. The more people cut back spending to increase their savings, the more the people they used to pay are forced to cut back their own spending, and so on in a downward spiral known as the Paradox of Thrift. Income shrinks so fast that savings fall instead of rise. The result: mass unemployment.

Keynes said that when companies don’t want to invest and consumers don’t want to spend, government must break the dangerous cycle by stepping up its own spending or cutting taxes, either of which will put more money in people’s pockets. That is not, contrary to some of his critics, a recipe for ever-expanding government: Keynes said governments should run surpluses during boom times to pay off their debts and soak up excessive private demand. (The U.S. ran small surpluses in two boom years of the Clinton administration.) Far from a wild-eyed radical, he said economists should aspire to the humble competence of dentists. He wanted to repair economies, not overthrow them.
