An Analysis of Asymmetry Effects of Oil Shocks on Economic Growth of the Oil-Exporting Countries: A Non-Liner Hidden Panel Cointegration

Asymmetric effects of oil shocks mean the difference between the positive and negative effects of oil shocks. Empirical studies show that these asymmetric effects can affect economic growth in oil-exporting countries as well as importing countries. In this regard, this paper tries to investigate the asymmetric effects of oil shocks on economic growth in oil-exporting countries (including Iran) during the period 1980-2011 by using hidden panel Cointegration. This approach, in addition to analyzing the long-term non-liner relationship between the variables, has another important capability for modeling asymmetry between different variables. Firstly, it has been shown that there is a long relationship between cumulative positive and negative components in crude oil prices and GDP in these countries by using Kao panel co-integration (hidden co-integration verification). Then, their long- run asymmetric relationships are measured by using dynamic ordinary least squares (DOLS). The results of this study show the negative effects of oil shocks are more than the positive effects on the economic growth of oil-exporting countries.
