Abstract: This study aims at determining the effects of inflation uncertainty on economic growth in Nigeria. Several studies have been carried out to ascertain the effects of inflation on economic growth in the literature, however only few studies could be found on the extent to which inflation uncertainty has affected growth. It was as a result of the dearth of literature in this area that gave the motivation for this study. The study uses the Generalized Autoregressive Conditional Heteroscedascity (GARCH) estimation technique to discover that inflation uncertainty directly and indirectly affects economic growth negatively in Nigeria.
