Paul Krugman: Rock Bottom Economics
The Inflation and Rising Interest Rates That Never Showed Up
Six years ago the Federal Reserve hit rock bottom. It had been cutting the federal funds rate, the interest rate it uses to steer the economy, more or less frantically in an unsuccessful attempt to get ahead of the recession and financial crisis. But it eventually reached the point where it could cut no more, because interest rates can’t go below zero. On Dec. 16, 2008, the Fed set its interest target between 0 and 0.25 percent, where it remains to this day.
The fact that we’ve spent six years at the so-called zero lower bound is amazing and depressing. What’s even more amazing and depressing, if you ask me, is how slow our economic discourse has been to catch up with the new reality. Everything changes when the economy is at rock bottom — or, to use the term of art, in a liquidity trap (don’t ask). But for the longest time, nobody with the power to shape policy would believe it.
