I study the incentives of Cournot duopolists to share their technologies with their competitor in markets where intellectual property rights are absent and imitation is costless. The trade-off between a signaling effect and an expropriation effect determines the technology-sharing incentives. In...

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.

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 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...

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...

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....

Patent application numbers grow exponentially in many industries, a phenomenon that has been linked to high fragmentation of patent ownership. Contradicting these findings and theoretical arguments, we show that such fragmentation is not a precondition for sudden and strong increases in...

This paper examines the role of dual sourcing (e.g., outside options) in vertical and horizontal relations. In a bilateral monopoly market, if either the upstream or downstream firm has outside options, the other firm could lose from seemingly positive shocks, e.g., market expansion or...
