We study the consumer welfare effects of mergers in airline networks. Based on the development of a general classification of affected routes, we apply a difference-indifferences approach to exemplarily investigate the price effects of the America West Airlines - US Airways merger completed in...

The welfare consequences of airline mergers have been analyzed almost exclusively in terms of ticket price. However, when flight frequency decisions are endogenized in a model,we can estimate measures of the relative importance of price and flight frequency. Hence, in a merger analysis, we can...

This paper models strategic interactions between a product supplier, a provider of information about product quality, and end users, in the context of road transportation. Using a game-theoretical analysis of suppliers' pricing strategies, we assess the social welfare effects of traffic...

This work estimates the impact of the 2018 French national railway strike (April to June) on the inter-city ridesharing usage and user welfare. We collected daily trip-level data from the API of BlaBlaCar, the largest inter-city ridesharing platform in Europe, and show that on an average strike...

In an oligopoly market subject to environmental regulation through tradable pollution permits, polluters' output decisions affect the price of polluting. With a pollution tax, this feedback effect is absent. In a permit regime, I show that the feedback effect increases strategic firms'...

We examine welfare effects of real-time pricing in electricity markets. Before stochastic energy demand is known, competitive retailers contract with final consumers who exogenously do not have real-time meters. After demand is realized, two electricity generators compete in a uniform price...

Mergers realize heterogeneous competitive effects on profits, production, and prices. To date, it is unclear whether differential merger outcomes are caused mostly by firms' technology or product market attributes. Furthermore, empirical merger studies conventionally assume that, conditional on...
