We study the problem of information sharing in oligopoly, when sharing decisions are taken before the realization of private signals. Using the general model developed by Raith (1996), we show that if firms are allowed to make bilateral exclusive sharing agreements, then some degree of...

Policies to correct market power and selection can be misguided when these forces co-exist. We build a model of symmetric imperfect competition in selection markets that parameterizes the degree of market power and selection. We use graphical price-theoretic reasoning to characterize the...

We examine the interplay of imperfect competition and incomplete information in the context of price competition among firms producing horizontally- and vertically-differentiated substitute products. We find that incomplete information about vertical quality (e.g., consumer satisfaction), which...

This study proposes a tractable imperfectly competitive economy where traders are socially connected with each other via an information network. We investigate the impact of information linkages on market equilibrium outcomes. In the linear-quadratic-normal framework, we establish the existence...

This paper proposes a spatial model of imperfect competition in markets with selection to investigate whether imperfect competition exacerbates or offsets inefficiencies caused by selection. We find that no degree of imperfect competition achieves the first-best efficient allocation. This holds...

We analyze firms' entry, production and hedging decisions under imperfect competition. We consider an oligopoly industry producing a homogeneous output in which risk-averse firms face an entry cost upon entering the industry, and then compete in Cournot with one another. Each firm faces...
