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...

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...

We develop a method to estimate a game’s primitives in complex dynamic environments. Because of the environment’s complexity, agents may not know or understand some key features of their interaction. Instead of equilibrium assumptions, we impose an asymptotic ε-regret (ε-AR) condition on...

We study firms' incentives to acquire private information in a setting where subsequent competition leads to firms' later signaling their private information to rivals. Due to signaling, equilibrium prices are distorted, and so while firms benefit from obtaining more precise private information,...

This paper introduces a number of game-theoretic tools to model collusive agreements among firms in vertically differentiated markets. I firstly review some classical literature on collusion between two firms producing goods of exogenous different qualities. I then extend the analysis to a...

Allowing for endogenous entry in the traditional Stackelberg setup with product differentiation, leads to reverting of the standard comparative static and limiting results. Unlike in the standard Stackelberg setup with barriers to entry, the leader's profit increases when the differentiation...

We prove that a sufficient condition for the core existence in a n-firm vertically differentiated market is that the qualities of firms' products are equally-spaced along the quality spectrum. This result contributes to see that a fully collusive agreement among firms in such markets is more...

We study the use of non-monetary incentives based on reciprocity to facilitate capacity sharing between two service providers who have limited and substitutable service capacity. We propose a parsimonious game theory framework, in which two firms dynamically choose whether or not to accept each...

Media content is an important privately supplied public good. While it has been shown that contributions to a public good crowd out other contributions in many cases, the issue has not been thoroughly studied for media markets yet. We show that in a standard model of commercial media bias,...
