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...

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

This paper examines the strategic effects of case preparation in litigation. Specifically, it shows how the pretrial efforts incurred by one party may alter its adversary’s incentives to settle. We build a sequential game with one-sided asymmetric information where the informed party first...

The quasi-linear quadratic utility model is widely used in economics. The knowledge of its exact origin is less widespread. A first contribution of the paper is to explain the genesis of this model. Next, we review the main properties of the general model, mainly following the previous...

Asymmetric information in procurement entails double marginalization. The phenomenon is most severe when the buyer has all the bargaining power at the production stage, while it vanishes when the buyer and suppliers' weights are balanced. Vertical integration eliminates double marginalization...

We study the behavior of a firm that consistently maximizes a misspecified profit function. We provide an equilibrium concept where the misspecification error remains undetected. We examine the uniqueness and stability of the equilibria. The model of the price-taking firm belongs to this class....

Many countries have reformed hospital reimbursement policies to provide stronger incentives for quality and cost reduction. The purpose of this work is to understand how the effect of such reforms depends on the intensity of local competition. We build a nonprice competition model to examine the...

We use French household data to estimate a structural model of female labor supply and use of paid child care outside the home. Child care costs are found to have little impact on the labor market participation decision of mothers. The model is used to study various policy issues. The influence...
