Strategic interactions between two-sided platforms depend not only on whether their decision variables are strategic complements or substitutes as for one-sided firms, but also - and crucially so - on whether or not the platforms subsidize one side of the market in equilibrium. For example, with...

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...

We study how competitive pressure influences the make-or-buy decision that oligopolistic firms face between producing an intermediate component in-house or purchasing it from a domestic supplier. We model outsourcing as a bilateral relationship in which the supplier undertakes relationship...

When and how do entrepreneurs sell their inventions? To address this issue, we develop an endogenous entry-sale asymmetric information oligopoly model. We show that lowquality inventions are sold directly or used for entry. Inventors who sell post-entry use entry to credibly reveal information...

We model a dynamic duopoly in which firms can potentially drive their rivals from the market. A consequence is that, for some ranges of parameters, the static Cournot equilibrium outcome cannot be sustained in an infinitely repeated setting. In those cases, there is a Markov perfect equilibrium...

A robust result in the literature on strategic incentives pioneered by Fershtman and Judd (1987), Sklivas (1987), and Vickers (1985) is that under quantity competition firm owners induce their managers to make aggressive quantity choices in the product market. We revisit this result in a...

In this paper, I develop a model of oligopoly with shareholder voting. Instead of assuming that firms maximize profits, the objective of the firms is decided by majority voting. This implies that portfolio diversification generates tacit collusion. In the limit, when all shareholders are...

Private equity backed firms have more leverage, more intense compensation contracts, and higher productivity than comparable non-private equity backed firms. We develop a theory of buyouts in oligopolistic markets that ties these facts to an explicit focus on buying assets with the intent of...

We develop an oligopoly model in which firms facing unionised domestic labor markets choose between producing an intermediate good in-house and outsourcing it to a nonunionised foreign supplier that makes a relationship-specific investment in developing the intermediate. The paper sheds light on...

Private equity firms are an important part of the industrial restructuring process. We argue that the key is temporary ownership. Buying to sell induces aggressive restructuring since the equilibrium trade sale price increases both because the profits of the acquiring incumbent increase and the...
