Retail Gasoline Price Cycles across Spatially Dispersed Gasoline Stations
研究使用加拿大某大都市区每日加油站价格数据，检验周平均价格或少量站点价格能否准确描述波动市场的定价，并探讨受限数据下对理论模型和反竞争行为政策的结论可靠性。
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.
