Proliferation is a strategic behavior which follows various logics: the wish for pre-emption is one of these but does not stand alone. Far from it. However, the literature associates almost systematically the question of proliferation to that of pre-emption, in such a way that the interest in...

We consider the problem of bargaining over the disclosure of interim research knowledge, between two participants in a R & D race or contest, for an ultimate, patentable invention. Licensing fee schedules, as fuctions of the "amount of knowledge" disclosed by the leading to the lagging agent,...

If a solution (on a closed family of games) satisfies dummy axiom (DUM) and independance of irrelevant strategies (IIS) then it also satisfies consistency (CONS) (proposition 2.21, Peleg and Tijs, 1996). The converse of this proposition is not true: CONS implies neither DUM nor IIS as shown in...

Efficiency scores of production units are measured by their distance to an estimated production forntier. Nonparametric DEA estimators are based on a finit sample of observed production units and radial distances are considered. We investigate the consistency and the speed of convergence of...

We consider the two-stage game proposed by Kreps and Scheinkman in the adress model of horizontal differenciation developed by Hotelling. Firms choose capacities in the first stage and then compete in price. We show that capacity precommitment softens price competitio drastically.
