We consider the efficiency of Cournot and Bertrand equilibria in a duopoly with substitutable goods where firms invest …

association started with a voluntary benchmarking aimed to increase the efficiency and effectiveness of the sector. Secondly … efficiency of these two evolutions. In particular, we adapt Free Disposal Hull (FDH) to estimate robust and conditional non …-oriented efficiency estimates. Parametric COLS (Fourier) tests show the robustness of the model with respect to the specification and its …

use efficiency which is not satisfied by the Banzhaf value. On the other hand, the Banzhaf value satisfies collusion … these axioms characterize the equal division solution. Further, we show that there is no solution that satisfies efficiency …, collusion neutrality and the null player property. Finally, we show that a solution satisfies efficiency, collusion neutrality …
