Money and Information in a New Neoclassical Synthesis Framework
在新新古典综合模型中引入货币的信息角色,用贝叶斯方法估计小规模粘性价格模型,发现货币能提高对潜在产出等不可观测变量的估计精度,并有助于解决价格谜题。
We consider an (otherwise standard) New Neoclassical Synthesis theoretical framework that allows a role for money. Money in our model has an informational role which facilitates the estimation of the unobserved shocks that drive potential output and thus the state of the economy. For this purpose we estimate a small-scale sticky price model using Bayesian techniques. Our findings support the view that money has information value. This is reflected in higher precision in terms of unobserved model concepts such as the natural rate of output. Moreover, our results highlight how modelling money demand can provide insights about structural features of the economy that may be important for the design of interest rate rules. Focusing on money also allows for a step towards resolving the price puzzle. Money demand shocks can confound monetary policy shocks to generate a perverse price response in vector autoregressions (VAR).
