Money Demand and Macroeconomic Stability Revisited1

چکیده
This paper reexamines the role of money demand for the local dynamics of a sticky price model where money enters the utility function and monetary policy is either conducted according to a Taylor-type interest rate rule or to a Friedman-type constant money growth rule. It is shown that activeness, which is commonly recommended as a device for a stabilizing interest rate policy, leads to stable and unique equilibrium path only if preferences are restricted in a way, which is hardly consistent with the view that money provides transaction services. In particular, the Taylor-principle relies either on the utility function to be separable or on end-of-period money holdings to provide utility. When, however, the beginning-of-period stock of money provides utility, interest rate policy should instead be passive if the utility function is specified in a (non-separable) way, which accords to an explicit specification of transaction services. Macroeconomic stability is, on the contrary, shown to be ensured if the central bank applies a constant money growth rule. JEL classification: E52, E41, E32.

Behavioral Pattern of Income Velocity of Money and Estimation of Its Function (The case of Iran)
Based on the “Aggregate Demand” theory, monetary policies are designed with the aim of achieving desirable level of macroeconomic goals through affecting the stock of money supplyand income velocity of money. Thus, the velocity (V)-as well as money supply - has significant impact, particularly on rate of inflation through expansionary or contractionary monetary policy. To focus on the velocity ...

متن کاملFlexibility of wages and macroeconomic instability in an agent-based computational model with endogenous money
We present a model of a dynamic and complex economy in which the creation and the destruction of money result from interactions between multiple and heterogeneous agents. In the baseline scenario, we observe the stabilization of the income distribution between wages and profits. We then alter the model by increasing the flexibility of wages. This change leads to the formation of a deflationary ...
متن کاملEffect of Sentiments on Macroeconomic Variables in Iran: A Dynamic Stochastic General Equilibrium Approach
This study aims to evaluate the effect of sentiments on Iran's economy through a New Keynesian Dynamic Stochastic General Equilibrium model in a closed economy. In this study, the coefficients of the proposed model are calibrated and estimated using the quarterly data of Iran's economy from 2004 to 2015. It shows that in the presence of sentiment, how stochastic impulses affect the main macroec...
