In the prisoners' dilemma game, the only evolutionary stable strategy is defection, even though nutual cooperation yields a higher payoff. Building on a paper by Robson (1990), we introduce mutants who have the ability to send a (costly) signal, i.e., the "secret handshake," before each round of...

We consider a connection networks model. Every agent has a demand in the form of pairs of locations she wants connected, and a willingness to pay for connectivity. A planner aims at implementing a welfare maximizing network and allocating the resulting cost, but information is asymmetric: agents...

We consider a generalization of the Minimum Cost Spanning Tree (MCST) model dubbed the Minimum Cost Connection Network (MCCN) model, where network users have connection demands in the form of a pair of target nodes they want connected directly, or indirectly. Given a network which satisfies all...

Game-theoretic models of international cooperation on climate change come to very different results regarding the stability of the grand coalition of all countries, depending on the stability concept used. In particular, the core-stability concept produces an encouraging result that does not...

I develop two related solution concepts, equilibrium coalitional behavior and credible equilibrium coalitional behavior, which capture foresight and impose the requirement that each coalition in a sequence of coalitional moves chooses optimally among all its available options. The model does not...

A simple symmetric 2 "e 2 strategic coordination game is analyzed in an evolutionary environment under the assumption that agents are able to condition their actions on observations made of the opponent. Agents are assumed to be associated with a profile of characteristics, of which all agents...

We analyze a cooperation game in an evolutionary environment. Agents make noisy observations of opponents' propensity to cooperate, called reputation, and form preferences over opponents based on their reputation. A game takes place when two agents agree to play. Pareto optimal cooperation is...

We analyze a college admissions game with asymmetric information between students and colleges. Students' preferences for colleges depend on the observable quality of the schools. In contrast, colleges' preferences for students depend on the latter's abilities, which are private information....

The aim of the paper is to compare the sensitivity of a government's fiscal policy and a central bank's monetary policy, which are in Nash equilibrium in the case of a non-cooperative game between the government and the central bank in Czechia, Hungary, and Romania. The analysis for each country...

In the context of the team's theory, this article shows that employees will be communicated, independent of their skill endowment, have a high skill endowment. In this way, the formation teams can lead to groups whose productivity is lower than that exhibited in terms of the skills they...
