We provide an evolutionary foundation to evidence that in some situations humans maintain either optimistic or pessimistic attitudes towards uncertainty and are ignorant to relevant aspects of the environment. Players in strategic games face Knightian uncertainty about opponents' actions and...

In this paper the standard Hotelling model with quadratic transport costs is extended to the multi-firm case. The sequential game consists of a location choice stage and a price setting stage. Considering locational equilibria it is shown that neither holds the Principle of Maximum...

The paper provides a micro-founded differentiated duopoly illustration of a beauty contest, in which the relative weight put on the competition motive of the payoffs is not exogenous but may be manipulated by the players. The conflict between the competition and the fundamental motives, already...

Allowing firms to cooperate in their R&D is an industrial policy which has received much attention in recent economics literature. Many of these contributions are based on the seminal analysis of d?Aspremont and Jacquemin [1988]. We provide a general version of their model which encompasses...

We model a duopoly in which two-sided platforms compete on both sides of a two-sided market. Platforms (or intermediaries) select the quality they offer consumers, and the prices they charge to consumers and firms. In this model, non-trivial competition on both sides induces non-quasiconcave...

In this paper, we fully characterize the Nash Equilibrium in the winner-take-all Bertrand Game, showing that a mixed strategy profile is a Nash Equilibrium, if and only if it is a zero operating profit one, and there exist at least two players whose bids are all unprofitable. Compared with...
