State-Dependent Pricing and the Dynamics of Money and Output
提出一种状态依赖定价模型,即企业调价取决于经济状态,并给出加总方法。模型能产生货币与产出的正相关和菲利普斯曲线,且货币冲击的影响依赖于当前产出水平。
Standard macroeconomic models of price stickiness assume that each firm leaves its price unchanged for a fixed amount of time. We present an alternative model in which the pricing decision depends on the state of the economy. We find a method of aggregating individual price changes that allows a simple characterization of macroeconomic variables. The model produces a positive money-output correlation and an empirical Phillips curve. In addition, the impact of monetary shocks depends crucially on the current level of output, which points to a natural connection between state-dependent microeconomics and state-dependent macroeconomics.
