A Test of the OPEC Cartel Hypothesis: 1974-1983
检验了1974-1983年间OPEC是否通过合谋推高油价，发现1974-1980年油价飙升期证据不足，但1981-1983年油价走软期有合谋影响迹象。
This paper tests whether the higher oil prices of the last decade could have been the result of producer collusion. We find little evidence that OPEC influenced oil prices during the years of skyrocketing prices (1974–1980), but there is evidence that it did so during the recent years of softening prices (1981–1983).
