Retail Gasoline Price Cycles across Spatially Dispersed Gasoline Stations
Studies of volatility in retail gasoline prices have used either weekly averages of the prices at a small subset of stations in a city or daily observations on prices at a small number of stations. This paper uses daily observations on station-specific prices within a large Canadian metropolitan area to address whether weekly average prices or prices for a small number of stations provide an accurate description of pricing in a market with volatility. This paper considers whether researchers using restricted data can draw meaningful conclusions about the appropriate theoretical model and the policy response to allegations of anticompetitive behavior.
