Natural resource curse: a non linear approach in a panel of oil exporting countries
MPRA: This paper explores the idea of regime switching as a new methodological approach to bring new insights into the natural resource curse hypothesis in the case of oil exporting countries. The basic idea is that when a threshold of oil dependence is passed, the relationship between economic growth and its determinants could move smoothly from a regime to another. Relying upon the estimation of a PSTR model, our findings offer strong evidence that oil revenues non-linearly impacts economic growth and that resource curse only exists under the condition of high oil dependence. More precisely, below the level of 51% of oil dependence, oil revenues have a positive impact on economic growth, whereas above this level, it have serious drawbacks on economic growth through inefficiencies into the quality and the quantity of government expenditures.
