Abstract

Concentrating on inflation persistence, this paper explores inflation dynamics in 12 oil-exporting countries with Dynamic Non-linear Panel models in 2002-2014. According to results, the level of inflation persistence in linear models is higher than the non-linear ones, so that based on OLS, fixed effects, and Arellano-Bond approaches, it is 0. 727, 0. 655, and 0. 59 respectively. With regard to the results, the estimated sign of inflation persistence is positive and statistically significant; demonstrating that current level of inflation would influence the future level of it. It can be also observed from the paper’s results that in comparison to ordered models, inflation persistence is higher in linear models. Considering heterogeneity and initial conditions, i. e. each country’s initial observed level of inflation, would make the estimations better. Empirical results demonstrate the low possibility of large jumps in inflation, and it tends to move toward higher, rather lower levels. The results reveal that the bigger the gap between existing inflation rate and target rate, the more the tendency of inflation to self-correct and move toward the desired level. Generally, the results show that inflation persistence is non-linear, and it varies depending on range of inflation rate. This means that inflation-stabilizing policies in the short-run would have long-run effects.
