THE DYNAMIC OF SUPPLY, DEMAND, AND COMPETITION<br />

G. Crude Oil <strong>Price</strong>s Skyrocketed in 2004 in Large Part Due to Unexpectedly<br />

Large Increases in Demand.<br />

Larger-than-predicted increases in world demand for crude oil caught producers off<br />

guard. OPEC, for example, had set 2004 production levels based on much lower projections for<br />

demand growth, so they were not producing enough crude oil to meet demand. Large demand<br />

increases from quickly industrializing countries, particularly China and India, made supplies<br />

much tighter than expected. In addition to increased demand, unexpected production difficulties<br />

reduced some producers’ crude output.<br />

II. CHANGES IN THE PRICE OF CRUDE OIL ARE THE PRIMARY<br />

EXPLANATION FOR CHANGES IN THE NATIONAL AVERAGE ANNUAL<br />

PRICE OF GASOLINE IN THE U.S.<br />

Variation in the price of crude oil drives most of the variation in the price of gasoline.<br />

John Cook, Director of the Energy Information Administration (EIA), has noted that “historically<br />

. . . we see fluctuations in retail prices almost entirely explained by movements in the underlying<br />

crude market.” 4 There is little doubt that changes in crude oil prices have a greater effect on<br />

retail prices than do changes in any other intermediate cost component. 5<br />

A simple regression 6 of the monthly average national price of gasoline on the monthly<br />

average price of West Texas Intermediate (WTI) crude confirms that the variation in the price of<br />

crude explains approximately 85 percent of the variation in the price of gasoline. 7 To illustrate<br />

this relationship, Figure 2-1 compares the yearly national average price of gasoline (excluding<br />

taxes) and the yearly average price of WTI crude oil from 1984 to January 2005. 8<br />
