Sticky prices, inventories, and market power in wholesale gasoline markets
نویسندگان
چکیده
A model with costly adjustment of production and costly inventories implies that wholesale gasoline prices will respond with a lag to crude oil cost shocks. Unlike explanations that rely upon menu costs, imperfect information, or long-term buyer/seller relationships, this model also predicts that futures prices for gasoline will adjust incompletely to crude oil price shocks that occur close to the expiration date of the futures contract. We test and confirm this implication. Examining wholesale price responses in 188 gasoline markets, we also find that firms with market power adjust prices more slowly than do competitive firms, consistent with the model.

We show how this can be tested by measuring whether relative prices of vehicles with different fuel economy ratings fully adjust to time series variation in gasoline pric...

متن کاملParadise at a Loss: Estimating Market Power in Hawaiian Gasoline Markets
We present a method for analyzing the exercise of market power in an industry in which each firm produces multiple competing goods. We use the method to study the market power of refiners in Hawaii. These refiners sell in two principal markets: jet fuel, with a buyers consortium, and gasoline, with diffuse buyers. With data from January 1992 through the new millennium, we find significant evide...
