The short answer, Zip, is that uncertainty about future prices forces all economic agents to hedge against that. If unions anticipate increased prices, they demand increased wages and a vicious cycle of expectation-driven inflation augments all other upward pressure on prices. So, if the government can remove that one particular uncertainty from the system, what was previously assumed to be the "best case" scenario on inflation rates could be beaten. This is done by tight monetary policy. Driving up interest rates and restricting the money supply discourages consumer spending and business investment. Prices are held in check as a consequence. Crow's experiment was a resounding success and is, absolutely, Canada's great contribution to the world of economics. It is now the standard policy that underlies all Western central banks' monetary policy.
Ah, I think I understand. Thanks for the explanation. Not so much "removing uncertainty" from the system but removing uncertainty from a particular variable to evaluate the consequence. In this case, holding inflation steady had unexpected results with respect to unemployment.
Well, with but a vague notion of economic policy myself, it will be interesting to see if there is an analog with natural systems, in which case you'd expect good and predictable short-term results, insterspresed with less frequent but more severe perturbation.
