The Costs of U.S. Oil Dependency

This paper first describes trends and future predictions of factors that determine U.S. dependence on oil and oil imports.

The premium has two main components: one reflects the risk of macroeconomic disruptions from oil price shocks, while the other stems from U.S. market power in the world oil market. Our best assessment of the oil premium is $5/barrel (equivalent to 12 cents per gallon of gasoline), which would warrant a broad, though moderately scaled, tax on all uses of oil
