This paper reviews forecasts of oil prices over the 1980s that were made in 1980. It identifies the sources of errors due to such factors as exogenous GNP assumptions, resource supply conditions outside the cartel, and demand adjustments to price changes. Through 1986, the first two factors account for most of the difference between projected and actual prices. After 1986, misspecification of the demand adjustments becomes a particularly troublesome problem.
