Price effects of spatial competition in retail fuel markets: the impact of a new rival nearby

Abstract

Our main goal in this paper is to understand the fuel market's spatial price competition. While most of the literature uses the density of gas stations and proximity to rivals as proxies for spatial competition, we measured the marginal increase in spatial competition by the entrance of a new rival nearby. The empirical results indicate that a new firm's entrance reduces prices, and the reduction is more significant the closer the new rival is. A new rival less than 100 meters away is related to a reduction of 2.6% on the typical incumbent firm price. When the new rival is located farther than 250 meters, the incumbent response is lower than 1%. For even greater distances, the effects were significant only when incumbents are unbranded. The extent of spatial competition matters for the outcome; while firms that already faced intense spatial competition are not impacted by having an entrant seller nearby, those facing low spatial competition had a significant price reduction.The pattern, entry of rivals closer matters more, remains when investigating the gasoline price, the ethanol price, and the gasoline wholesale-retail margins in Brazil.

Dimensions of competition in urban cannabis markets

“…The geographic dimension of competition has important implications for both price competition and for public policy. In one telling study, Cardoso et al (2022) find that a new gasoline retailer near established retailers causes a general reduction in the price of gasoline. Thus, within the retail cannabis market, clusters of firms will likely report higher competition over price than those without nearby competitors.…”
