Inflation and inflation uncertainty: evidence from the Caribbean region

Purpose - The purpose of this paper is to extend the literature on the relationship between inflation and inflation uncertainty by examining three Caribbean countries: the Bahamas, Barbados, and Jamaica. Design/methodology/approach - ARMA‐GARCH models are used to estimate inflation uncertainty along with Granger‐causality tests to infer the relationship between inflation and inflation uncertainty. Findings - The results reveal that both the Bahamas and Jamaica exhibit a high degree of volatility persistence in response to inflationary shocks, while Barbados has a much lower persistence measure. Granger‐causality tests indicate that an increase in inflation has been a positive impact on inflation uncertainty for each country. However, an increase in inflation uncertainty yields a decrease in inflation in the case of Jamaica. In summary, the results for the Bahamas and Barbados support the Friedman‐Ball hypothesis, whereas the results for Jamaica support Holland's stabilization‐motive hypothesis. Research limitations/implications - Future research on inflation and inflation uncertainty can be extended to incorporate possible regime shifts associated with fiscal and monetary policy. Originality/value - The study fills a void in the literature with respect to the inflation‐inflation uncertainty nexus for Caribbean countries. The results of the paper may be useful to policymakers in the formulation of fiscal and monetary policy.
