The end of Keynes

The eclipse of Keynesian economics proceeds. When Keynes wrote “The General Theory of Employment, Interest and Money” in the mid-1930s, governments in most wealthy nations were relatively small and their debts modest. Deficit spending and pump priming were plausible responses to economic slumps. Now, huge governments are often saddled with massive debts. Standard Keynesian remedies for downturns — spend more and tax less — presume the willingness of bond markets to finance the resulting deficits at reasonable interest rates. If markets refuse, Keynesian policies won’t work.

Countries then lose control over their economies. They default on maturing debts or must be rescued with loans from friendly countries, the International Monetary Fund (IMF), government central banks (the Federal Reserve, the European Central Bank) or someone. There are other reasons why Keynesian policies might fail or be weakened. But they pale by comparison with the potential veto now posed by bond markets. Ironically, the past overuse of deficits compromises their present utility to fight high unemployment…

Governments have ceded power to bond markets by decades of shortsighted behavior. The political bias is to favor short-term stimulus (by lowering taxes and raising spending), which is popular, and to ignore long-term deficits (by cutting spending and raising taxes), which is unpopular. Debt has risen to hazardous levels, undermining Keynesian economics as taught in standard texts.
