Determining how monetary policy makers react to changes in key economic variables has been of major interest to monetary economists. Estimates of monetary policy rules (reaction functions) are a widely used method for doing this. Behavior differs under different policy regimes, as in rule-based systems or chronic inflation. In practice, estimates of instrument rules have been used to descri...

In this paper we study the inefficiencies of the monetary equilibrium and optimal monetary policies in a search economy. We show that the same frictions that give fiat money a positive value generate an inefficient quantity of goods in each trade and an inefficient number of trades (or search decisions). The Friedman rule eliminates the first inefficiency and the Hosios rule the second. A monet...

the subject of monetary policy orientation and tailoring a framework within which the credibility and desirability of the policies and the policy makers is enhanced, while the most important goal of policies, i.e reaching to and preserving a low and stable inflation rate is achieved, has recently been a controversial issue for a large number of economists. in fact the necessity arised since the...

This study aimed to examine the effects of monetary policy on macroeconomic variables with regard to the collateral constraint. For this purpose, a dynamic stochastic general equilibrium (DSGE) was developed for Iran’s economic status. Two scenarios were considered as to account for the behavior of the central bank. In the first scenario, the monetary rule is modeled according to the GDP gap an...

Oil price shocks are the main source of macroeconomic fluctuations in oil exporting countries. It is believed that appropriate monetary policy can help to stabilize these unwanted variations toward optimal allocations. A stochastic dynamic general equilibrium model featuring the properties of both cost push and wealth effect transmission channels is developed for the Iranian economy. In thi...

Monetary policy rule is an approach to avoid time inconsistency problem as regarded by new classical economist to choose a time plan for policy making in order to maximize households’ well-being. The foundation of time inconsistency problem is not coincidence of expectations as an ex-ante variable, which is expected variable, with actual variable as an ex-post variable. Expectations in Finn K...

HOULD MONETARY POLICY be determined by a legislated rule or by a monetary authority’s discretion? Henry Simons (1936) first raised this issue as a choice between rules and authorities, terms little different than those used in recent discussions. He stresses the value of a rule, such as a law, instead of reliance on an authority’s discretion because “definite, stable, legislative rules of the g...

Standard monetary policy analysis built upon the New Keynesian model suggests that an optimal monetary policy rule is one which minimizes a weighted sum of the variance of inflation and the variance of the output gap. As one might expect, the Taylor rule evaluates well under this criteria. Recent calls for nominal GDP targeting therefore must contend with Taylor rule as an alternative approach ...

This paper examines under what conditions fiscal policy in the form of government spending should contribute to macroeconomic stabilisation. To this end optimal fiscal targeting rules minimising the microfounded social loss are examined in the following settings. Firstly, for the benchmark New Keynesian model, where monetary policy is unconstrained, a neutrality result for fiscal obtains: fisca...

in a managed floating exchange rate regime, one of the most important issues is the degree to which the monetary authorities intervene in the foreign exchange market.  the appropriate level of intervention in the foreign exchange market can be discussed in a framework which emphasizes the trade-off between changes in the country’s level of international reserves and minimizes the country’s real...
