The estimation of inflation volatility is important to Central Banks as it guides their policy initiatives for … Heteroscedasticity (GARCH) family with a view to providing a parsimonious approximation to the dynamics of Nigeria's inflation volatility … and food CPI, implying that the impacts of inflation shocks on their volatilities die away very slowly. However, the …

In this paper we propose a model for monthly inflation with stochastic trend, seasonal and transitory components with …, the uncertainty associated with these components may increase with the level of inflation as postulated by Friedman. We … experiments. Finally, we use auxiliary residuals to detect conditional heteroscedasticity in monthly inflation series of eight …

We propose a noncausal autoregressive model with time-varying parameters, and apply it to U.S. postwar inflation. The … model fits the data well, and the results suggest that inflation persistence follows from future expectations. Persistence … curve indicate that current inflation also depends on past inflation although future expectations dominate. The implied …

The persistence property of inflation is an important issue for not only economists, but, especially for central banks …, given that the degree of inflation persistence determines the extent to which central banks can control inflation. Further …, not only is the level of inflation persistence that is important in economic analyses, but also the question of whether …

inflation volatility.Also, causality tests results indicate that changes in the exchangerate, output gap volatility, and output … gap will have permanent andtemporary causal effects on inflation volatility. The policymakersshould carefully consider … these results to implement appropriatepolicies to reduce inflation volatility. The finding that the shocks areof temporary …

framework we examine the twelve potential intertemporal relationships between inflation, growth and their respective … uncertainties using US data. We find that high inflation is detrimental to output growth both directly and indirectly via the … nominal uncertainty.
