How does the concept of "network effects" challenge the notion of zero-sum competition in some industries?

Then we study continuity properties of stochastic game problems with respect to various notions of convergence of information structures. For zero-sum games, ... They showed that in the case of a zero-sum game, the only Nash equilibrium payoff of the repeated game is the value of the stage-game. Thus, although the ... Section C studies counterfactual predictions in two-player zero-sum games. Section D studies counterfactuals in a first-price auction with reserve price. We further relate these properties of the Nash solutions for these two games to some of the distinct features of zero-sum games and team problems. Previous ... Dec 9, 2024 ... (1) We design a distributed algorithm for seeking a BNE in subnetwork zero-sum games. This game model can be regarded as a generalization of ... Dec 2, 2016 ... Zero-sum games; Incomplete information; Signalling games; Hypothesis testing equilibrium; Enter deterrence games; Equilibrium refinement ... However, the local counterfactual for welfare is unique in two-player zero-sum games, as is shown in the Supplemental Appendix. Partially Observed Outcomes In ... ... learning has been extended to general-sum extensive form games with perfect information. ... zero-sum game with leader and follower. It was called Minimax-Q which ... The zero-sum game concept helps explain why indexing can be an attractive investment strategy. The theory states that the aggregate holdings of all investors in ... Mar 3, 2008 ... Lack of information on one side: particular case where all the players but one perfectly know the stage game which is repeated. Zero-sum games: ...
