Unstable Inflation Targets∗

چکیده
This paper studies long-run inflation targets and stability in an imperfect information environment. When central banks set an inflation target that is not fully communicated, agents draw inferences about inflation from recent data and remain alert to structural change in their econometric model by forming expectations from a forecasting model that is estimated via discounted least squares. Inflation targets can lead agents’ beliefs to depart from rational expectations through two channels. First, implementing a higher inflation target can lead to overshooting of the target. Second, there can be nearly self-fulfilling inflation, disinflation, or deflation that arises as an endogenous response to shocks. JEL Classifications: E52; E32; D83; D84

Interaction between Fiscal and Monetary Policy in a Dynamic Nonlinear Model
The objective of this study is to verify the dynamics between fiscal policy, measured by public debt, and monetary policy, measured by a reaction function of a central bank. Changes in monetary policies due to deviations from their targets always generate fiscal impacts. We examine two policy reaction functions: the first related to inflation targets and the second related to economic growth ta...
متن کاملChaotic New Inflation and Formation of Primordial Black Holes
It is shown that in a number of scalar potentials with an unstable local maximum at the origin chaotic inflation is followed by new inflation if model parameters are appropriately chosen. In this model density fluctuation can have a large-amplitude peak on the comoving Hubble scale at the onset of the slow-roll new inflation and can result in formation of appreciable amount of primordial black ...
متن کاملMisalignment on the Persistence of Inflation in Iran
The purpose of this study is to investigate the impact of exchange rate misalignment on inflation persistence. For this purpose, Vector Auto Regression method and Markov Switching model is used for quarterly data during 1989:4 -2014:3. The results show that, the impact of liquidity growth and exchange rate misalignment on inflation persistence is positive. On the other hand, GDP growth has a ne...
متن کاملFigure 1 Consumer Prices : 1971 to February 1997 , 12 - Month Percentage
Johnson’s paper addresses one of the main issues of central banking: How successful have monetary authorities been in acquiring credibility for their inflation objectives? Johnson’s approach is both simple and elegant. For countries with explicit inflation targets, he examines whether inflation expectations are consistent with those targets. Since not all central banks have explicit inflation t...
متن کاملAsymmetric Behavior of Inflation in Iran: New Evidence on Inflation Persistence Using a Smooth Transition Model
T his paper investigates the asymmetric behavior of inflation. We use logistic smooth transition autoregressive (LSTAR) model to characterize the regime-switching behavior of Iran’s monthly inflation during the period May 1990 to December 2013. We find that there is a triple relationship between the inflation level, its fluctuations and persistence. The findings imply that the behavi...
