OPEC and non-OPEC oil production and the global economy
研究了1974-2012年欧佩克与非欧佩克石油产量对彼此及全球经济的动态影响，发现两个时期关系不同，非欧佩克产量对油价影响更大。
Hamilton identifies 1973 to 1996 as “the age of OPEC” and 1997 to the present as “a new industrial age.” During 1974–1996 growth in non-OPEC oil production Granger causes growth in OPEC oil production. OPEC oil production decreases significantly with positive shocks to non-OPEC oil production in the earlier period, but does not do so in the “new industrial age”. In the “new industrial age” OPEC oil production rises significantly with an increase in oil prices, unlike during “the age of OPEC” period. OPEC oil production responds significantly to positive innovations in global GDP throughout. Over 1997:Q1–2012:Q4 the negative effect on real oil price of positive shocks to non-OPEC oil production is larger in absolute value than that of positive shocks to OPEC oil production. The cumulative effects of structural shocks to non-OPEC oil production and to real oil price on OPEC oil production are large. The cumulative effects of structural shocks to OPEC production and real oil price on non-OPEC production are small. Results are robust to changes in model specification. An econometric technique to predict growth in OPEC oil production provides support for the results from the SVAR analysis. Results are consistent with important changes in the global oil market.
