Rothbard on deflation
Kudos to William Anderson today for drawing the relevant passages out of my favorite book, Man, Economy, and State regarding the true nature of inflation versus deflation. Nobody explains the time preference and redistributionary impacts of inflation, nor the corrective influence exerted by deflation, better than Rothbard.
Here's the key passage:
Just as inflation is generally popular for its narcotic effect, deflation is always highly unpopular for the opposite reason. The contraction of money is visible; the benefits to those whose buying prices fall first and who lose money last remain hidden. And the illusory accounting losses of deflation make businesses believe that their losses are greater, or profits smaller, than they actually are, and this will aggravate business pessimism.
It is true that deflation takes from one group and gives to another, as does inflation. Yet not only does credit contraction speed recovery and counteract the distortions of the boom, but it also, in a broad sense, takes away from the original coercive gainers and benefits the original coerced losers. While this will certainly not be true in every case, in the broad sense much the same groups will benefit and lose, but in reverse order from that of the redistributive effects of credit expansion. Fixed-income groups, widows and orphans, will gain, and businesses and owners of original factors previously reaping gains from inflation will lose. The longer the inflation has continued, of course, the less the same individuals will be compensated.
Some may object that deflation "causes" unemployment. However, as we have seen above, deflation can lead to continuing unemployment only if the government or the unions keep wage rates above the discounted marginal value products of labor. If wage rates are allowed to fall freely, no continuing unemployment will occur.
