I am looking for studies in which the effect on demand of different prices of gasoline at different gas stations in the same area is measured or estimated (on the same day or hour).
This question has to do with price elasticity. Since gasoline is strongly needed on a daily basis in equal amounts by many people, its price elasticity is quite low and estimated to be in the range of -0.02 to -0.04 in the short term.
But I want to look a bit deeper: Can (and were) the effect on demand of different prices of gasoline at different gas stations in the same area be measured?
