This note investigates the effects of a large horizontal merger on the shape of the 1-to-12 h price menus offered by parking garages in Paris. The merger caused low-end prices to increase proportionally more than high-end prices. This results in larger discounts on longer hours and hence in more price discrimination between short-term and long-term motorists.
