In the crude oil market the phenomenon of Long Memory can be easily identified with the help of the simple (but effective) methodology of Katsumi Shimotsu. The Exact Local Whittle estimator and two testing strategies provide a strong assessment of the phenomenon. We present evidences and we...

This study investigates the asymmetric and time-varying causality between inflation and inflation uncertainty in South Africa within a conditional Gaussian Markov switching vector autoregressive (MS-VAR) model framework. The MS-VAR model is capable of determining both the sign and direction of...

This study investigates the relationship between inflation, inflation uncertainty and output in Tunisia using real and nominal data. GARCH-in-mean model with lagged variance equation is employed for the analysis. The result shows that inflation uncertainty has a positive and significant effect...

This paper studies the impact of inflation on inflation uncertainty in a modelling framework where both the conditional mean and conditional variance of inflation are regime specific, and the GARCH model for inflation uncertainty is extended by including a lagged inflation term in each regime....

We use over two hundred years of US inflation data to examine the impact of inflation uncertainty on inflation. An analysis of the full period without allowing for various regimes shows no impact of uncertainty on inflation. However, once we distinguish between recessions and non recessions, we...

Purpose – The purpose of this paper is to establish a link between inflation uncertainty and interest rates for five inflation-targeting countries. Design/methodology/approach – The approach takes the form of a time-varying parameter model with a Generalized Autoregressive Conditional...

This paper investigates the links between inflation, its uncertainty and economic growth in five ASEAN countries over the period 1980: Q1-2011: Q3. We rely on the Exponential GARCH (EGARCH) model to explore the causal relationship among the three variables. The major findings are: (i) inflation...

This paper estimates a time-varying AR-GARCH model of inflation producing measures of inflation uncertainty for the euro area, and investigates the linkages between them in a VAR framework, also allowing for the possible impact of the policy regime change associated with the start of EMU in...

This note, employing a GARCH model, finds a positive and significant relationship between the level and variability of monthly inflation in India in the period 1957-2005, with causation running from inflation to uncertainty about future inflation, as hypothesized by Friedman. To the extent that...
