Can policymakers deliver on promises to lower the overall price level?
Core argument: Greece's early-2010s slump pushed unemployment to 28% while prices fell only a few percent, illustrating that even depression-level downturns produce little deflation in modern economies.
With the unique and complicated exception of Japan, modern economies almost never experience deflation — overall falling prices. We may sometimes see price declines for commodities like eggs and falling prices for goods like computer equipment experiencing rapid technological progress. But the broad basket of consumer goods considered in the Consumer Price Index and similar measures doesn’t fall unless the economy is deeply depressed, and even then doesn’t fall by much. To see what I mean, consider the example of Greece, which experienced a Great Depression-level slump in the early 2010s. Unemployment rose to 28%, and prices did fall a bit — but only by a few percent: In the U.S., the Great Recession of 2007-2009, the worst slump since the Great Depression, led to slower inflation — prices rising more slowly than before. But it didn’t cause deflation. So would-be policymakers shouldn’t promise to bring the overall level of prices down. They won’t be able to deliver and will face a political backlash.
