Communication and Coordination in Games with Third-Party Externalities
نویسنده
چکیده
Decision-makers in coordination problems often impose negative externalities on non-decision-making third parties. This thesis investigates whether the introduction of pre-play communication in such coordination problems can work to alleviate such negative externalities, consequently increasing group welfare. Unlike previous studies, we find no significant effect following the introduction of communication in this laboratory experiment. Further, there is no evidence to suggest that communication opportunities heighten social image concerns. Such social image concerns might act as a mechanism to induce socially efficient behavior and alleviate negative externalities. A small subject pool and the nature of the communication technology employed are important factors to consider when interpreting the results.

Shapley Value for Games with Externalities and Games on Graphs
The Shapley value [46] is one of the most important solution concepts in coalitional game theory. It was originally defined for classical model of a coalitional game, which is relevant to a wide range of economic and social situations. However, while in certain cases the simplicity is the strength of the classical coalitional game model, it often becomes a limitation. To address this problem, a...
متن کاملCooperative Benefit and Cost Games under Fairness Concerns
Solution concepts in cooperative games are based on either cost games or benefit games. Although cost games and benefit games are strategically equivalent, that is not the case in general for solution concepts. Motivated by this important observation, a new property called invariance property with respect to benefit/cost allocation is introduced in this paper. Since such a property can be regar...

متن کاملPartial bandwagon effects and local interactions
We consider partial bandwagon properties in the context of coordination games to capture the idea of weak network externalities. We then study a local interactions model where agents play a coordination game following a noisy best-reply process. We identify conditions such that Globally Pairwise Risk Dominant strategies are selected. Examples include arbitrary 3× 3 coordination games and n×n su...
