摘要：This research presents supportive evidence for the positive and significant relationship between the level and variability of inflation in the Sudan, using annual data for the period 1960 – 2005. CPI inflation rate was estimated by variety of GARCH related models to account for time varying inflation volatility since the estimated conditional volatility can serve as a proxy for uncertainty. EGARCH was found to correctly specify and estimate the conditional variance of inflation with possibility of a simultaneous feedback relationship between inflation and uncertainty.
