We study an infinitely-repeated game of oligopolistic price leadership in which one firm, the leader, proposes a supermarkup over Bertrand prices to a coalition of rivals. We estimate the model with aggregate scanner data on the beer industry and find the supermarkup accounts for 6% of price....

We determine the endogenous order of moves in which the firms set their prices in the framework of a capacity-constrained Bertrand-Edgeworth triopoly. A three-period timing game that determines the period in which the firms announce their prices precedes the price-setting stage. We show for the...

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...

We consider the issue of first versus second-mover advantage in differentiated-product Bertrand duopoly with general demand and asymmetric linear costs. We generalize existing results for all possible combinations where prices are either strategic substitutes and/or complements, dispensing with...

This is a survey of the economic principles that underlie antitrust law and how those principles relate to competition policy. We address four core subject areas: market power, collusion, mergers between competitors, and monopolization. In each area, we select the most relevant portions of...
