Abstract

Station-specific retail gasoline prices are publicly available on websites such as GasBuddy.com, but the potential sample selection biases that might exist in these data have not previously been examined. To this end, two sets of prices were compiled for 27 stations in Guelph, Ontario, in late 2005: an unbalanced panel collected every 12 h from OntarioGasPrices.com, and a balanced panel collected eight times per day by direct observation. It appears that “Internet data” can be reliable for answering questions that require daily, company-operated, major brand station prices, but not if one needs very high frequency data or prices for certain types of independent stations.
