Suicidal Economics

I do not think that any economist would dare to say that the current US economic crisis has been caused by underconsumption. With zero personal saving and a large budget deficit the Bush administration has run one of the most aggressive Keynesian policies in history. Not only has adherence to Keynes's principles not averted the current economic disaster, it has greatly contributed to causing it. The Keynesian desire to manage aggregate demand, ignoring the long-run costs, pushed Alan Greenspan and Ben Bernanke to keep interest rates extremely low in 2002, fuelling excessive consumption by the household sector and excessive risk-taking by the financial sector. Most importantly, it has been the Keynesian training of our policy-makers that has led them to ignore the role that incentives play in economic decisions. The main difference between Keynes and modern economics is the focus on incentives. Keynes studied the relation between macroeconomic aggregates, without any consideration for the underlying incentives that lead to the formation of these aggregates. By contrast, modern economics base all their analysis on incentives. In 1998, when the Fed co-ordinated the bail-out of Long Term Capital Management, it did not care about the impact this decision would have on the incentives to take risk and price liquidity appropriately. When Mr Bernanke engineered the bail-out of Bear Stearns, he did not care about the impact this decision would have on the other investment banks' incentives to raise equity capital at rock-bottom prices. When he changed his position twice in the space of two days, letting Lehman fail, but bailing out AIG, he did not care about the impact it would have on investors' confidence and incentives to invest. It is this erratic behaviour that has spooked the market and created the current economic crisis: in a recent survey 80% of Americans declare that they are less confident of investing in the market as a result of the way the government has intervened...

Keynesianism has conquered the hearts and minds of politicians and ordinary people alike because it provides a theoretical justification for irresponsible behaviour. Medical science has established that one or two glasses of wine per day are good for your long-term health, but no doctor would recommend a recovering alcoholic to follow this prescription. Unfortunately, Keynesian economists do exactly this. They tell politicians, who are addicted to spending our money, that government expenditures are good. And they tell consumers, who are affected by severe spending problems, that consuming is good, while saving is bad. In medicine, such behaviour would get you expelled from the medical profession; in economics, it gives you a job in Washington.
