We adapt the exclusion model of Choné and Linnemer (2014) to reflect the notion that dominant firms are unavoidable trading partners. In particular, we introduce the share of the buyer’s demand that can be addressed by the rival as a new dimension of uncertainty. Nonlinear price-quantity...

We study the exclusionary properties of nonlinear price-quantity schedules in an Aghion-Bolton style model with elastic demand and product differentiation. We distinguish three regimes depending on whether and how the price of the incumbent good is linked to the quantity purchased from the rival...

We consider a simple tournament model in which individuals auto-select into the contest

We study the exclusionary properties of nonlinear pricing by dominant firms in a static environment. Optimal price schedules are nonlinear when the rivals’ sensitivity to competitive pressure varies with the “contestable share” of the market. When buyers can dispose of unconsumed units at...

Most retrospective merger studies resort to the treatment effect approach, comparingthe price dynamics in a treatment group and in a control group. We propose asystematic method to construct the groups, which applies to any industry with spatialcompetition. The method is consistent with the fact...

Nous examinons, dans le cadre d'une relation verticale entre un producteuret un distributeur, les incitations que reçoivent chacun des agents à certierun produit de qualité inconnue des consommateurs. Nous montrons que cettedécision est à l'origine de conits additionnels entre l'amont et...
