To foster competition, governments can intervene by auctioning licenses to operate, or by imposing divestitures. The Dutch government has done exactly that, organizing auctions to redistribute tenancy rights for highway gasoline stations and imposing divestitures of such stations on the four major companies. We evaluate this policy experiment and find that the auctioning of licenses without an obligation to divest has no discernible effect on prices. An obligation to divest lowers prices by 1.3–2.3% at divested sites. Moreover, prices decrease by 0.9–1.2% at sites nearby. This suggests that the observed price decreases are at least partly due to competitive spillovers.
