Retail and wholesale gasoline price adjustments in response to oil price changes

摘要

This research examines the long-run relationship between the spot oil price and retail and wholesale gasoline prices. Recent research suggests that the response of the retail gasoline price is faster and the size of the change is larger, in magnitude, following a crude oil price increase compared with periods when the crude oil price is falling; however, some recent papers examining potential asymmetries present mixed results. Our results from a common threshold model estimating the adjustment of gasoline prices and the spot oil price suggest a long-run relationship between retail and wholesale gasoline prices and the crude oil price. Further, results here suggest that both retail and wholesale gasoline prices respond symmetrically to an oil price shock in the long run, indicating little market power by gas stations and wholesalers.
