In this paper, we take a first step toward exploring empirically the product assortment strategies of oligopolistic firms. Our starting point is a discrete-choice demand model for differentiated products. We incorporate the demand model into an equilibrium supply model, in which firms compete by...

In this paper, I identify and examine a class of normative theories that may cause rational managers to inadvertently destroy firm value in equilibrium. The problem occurs when firms take prescribed actions that result in the outcomes predicted by the theory, even though the theory rests upon...

This paper proposes a strategic model of entry that allows for positive and negative spillovers among firms. The model is applied to a novel dataset containing information about the store configurations of all US regional shopping centers and is used to quantify the magnitude of inter-store...

This survey presents in a historical way the main contributions to the hardcore theory of aggregative games and the applications of this model to several fields of economics, other social sciences and engineering

This paper studies how product differentiation affects substitution patterns and firms' markups in oligopolistic markets where products are differentiated over multiple attributes and consumers have linear-quadratic preferences. Under these assumptions, the cross-price elasticity between any two...

We provide a model of dynamic duopoly in which firms face financial constraints and disappear when they are unable to fulfill them. We show that, in some cases, Cournot outputs are no longer supported in equilibrium, because if these outputs were set, a firm may have incentives to ruin the...

In this paper we study the nature of incentive contracts and organizational modes in a game where the firms' owners endogenously determine the order of moves at the quantity-setting stage, can choose to delegate the production decision to a manager and write appropriate incentive contracts. It...

This paper presents a new decomposition approach for measuring deterrence motives in dynamic oligopoly games. Our approach yields a scale-free and interpretable measure of deterrence motives that informs researchers about the proportion for which deterrence motives account of all entry motives....

We show that the vertical delegation of decision-making authority to agent firms can act as a credible strategic commitment even when contracts are unobservable (or renegotiable) if and only if multilateral delegation is combined with decentralized ownership of the agent firms. In this case, the...
