What is new? The role of asymmetry and breaks in oil price–output growth volatility nexus

Abstract

AbstractThis study examines the role of asymmetry and breaks in oil price–output growth volatility nexus. A representative of 10 countries was selected from net oil‐exporting and‐importing economies for the period 1986–2017. It is hypothesised that countries respond differently to changes in oil price. To prove this point, we use the recent nonlinear ARDL of Shin et al. (), based on the framework of the dynamic common correlated effect of the heterogeneous panel of Chudik and Pesaran (), to decompose oil price into positive and negative partial sums. Our results show that without accounting for breaks, asymmetry only matters for net oil exporters in both short‐ and long run. However, accounting for breaks expanded the importance of asymmetry to net oil importers (in the short run). These results are robust to changes in the measures of oil price and growth volatility.
