in this research, the attempt was made to test the existence of the natural rate hypothesis in iran, by using a johansson cointegration test. the results do not reveal any long run relationship between inflation and unemployment in iran for 1340-1386 periods. because of the time varying nature of nairu, the hp filter was applied to estimate the time series of nairu. comparing the nairu time ser...

Two major developments marked the monetary sector in emerging market economies (EMEs) in the 1990s. One was the steady decline in the inflation rate to low levels in the second half of the decade. The other was the growing preference for conducting monetary policy based on inflation targeting. For example, average inflation in 10 of the 14 EMEs discussed in this paper declined to a single digit...

reputation of a monetary’s authority, is an agents believe on his to control of deviation between targeting inflation and observed inflation. on one hand , a monterey’s authority, can throw agent’s trust to his polices, leading to lower inflation expectations and inflation. but on the other hand, government pressure on the monetary authority to do discretionary monetary policy( such as creation...

There is by now a large consensus in modern monetary policy. This consensus has been built upon a dynamic general equilibrium model of optimal monetary policy as developed by, e.g., Goodfriend and King (1997), Clarida et al. (1999), Svensson (1999) and Woodford (2003). In this paper we extend the standard optimal monetary policy model by introducing nonlinearity into the Phillips curve. Under t...

The prospects for achieving price stability and full employment sooner with wage and price controls than with traditional monetary and fiscal actions alone depend on the ability of the wage and price controls to dampen expectations of inflation. Until expectations of inflation are substantially reduced, inflationary pressures \vill remain strong evcn though measured prices are constrained by go...

The Great Moderation is often characterized by the decline in the variability of output and inflation from earlier periods. While a multitude of explanations for the Great Moderation exist, notable research has focused on the role of monetary policy. Specifically, early evidence suggested that the increased stability has been associated with monetary policy that responded much more strongly to ...

This paper explores time variation in the dynamic effects of technology shocks on U.S. output, prices, interest rates as well as real and nominal wages. The results indicate considerable time variation in U.S. wage dynamics that can be linked to the monetary policy regime. Before and after the "Great Inflation", nominal wages moved in the same direction as the (required) adjustment of real wage...
