Empirical work on price-cost margins often treats costs as exogenous. Allowing for endogenous costs when estimating price-cost margins is the topic of this paper. Methodologically, the endogenous cost model we propose leads to an additional equation that allows for the simultaneity in price...

This thesis strives to offer new insights in two main areas. First, in the well-researched domain of payment cards chapters 2 and 3 investigate an aspect that has hitherto been scantly examined, namely, the fact that merchant usage fees differ substantially among merchant sectors. Additionally,...

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...

We consider a possible game-theoretic foundation of Forchheimer’s model of dominant-firm price leadership based on quantity-setting games with one large firm and many small firms. If the large firm is the exogenously given first mover, we obtain Forchheimer’s model. We also investigate...

In this paper we examine how trade liberalization affects collusive stability in the context of multimarket interactions. The model we consider is a segmented-markets duopoly in which price-setting firms pool their incentive constraints across markets to sustain their most collusive outcome. We...

When firms set prices and face entry costs, efficiency in production and in entry are not simultaneously achieved, generating the possibility that regulatory interventions can lead to efficiency enhancements. We show through the Bertrand model that in markets with public entry and regular...

This paper develops a model of post-liberalization price competition between airlines on the route Rio de Janeiro - São Paulo. The intense price competition episode culminated in the rupture of a thirty-nine year-old cooperative structure - the air shuttle service cartel. By modeling and...
