A simple model of Irving Fisher's price-level stabilization
构建了一个简单模型，检验费雪稳定价格水平的四种货币规则，发现基于价格缺口（实际与目标之差）的规则比其他规则更快、更平稳地实现价格稳定，且优于固定货币存量规则。
Fishers advice to the policymakers: Adjust the money stock to correct price-level deviations from target. He neglected to say whether money should respond (1) to the gap between actual and target prices, (2) to the gaps rate of change, (3) to the gaps cumulative value over time, or (4) to some combination of these. While all four versions of Fishers rule deliver price stability in the model presented here, the first does so more promptly and smoothly than the others and outperforms a constant money-stock rule as well.
