The paper defines a family of nested non-cooperative simultaneous finite games to study coalition structure formation … with intra and inter-coalition externalities. The novelties of the paper are: a definition of every games embeds a … coalition structure formation mechanism. Every game has two outcomes - an allocation of players over coalitions and a payoff …

information to agents, who consider joining a coalition. The agents' actions can cause harm by contributing to a public bad. The … coalition size, as a function of beliefs of agents, is an endogenous variable, induced by the information sender. The optimal … information mechanism from the general set of public information mechanisms, in coalition formation games is derived. I also apply …

The paper studies when efficient allocations are implementable via coalition-proof mechanisms. When ambiguous … implementable via interim coalition incentive compatible mechanisms if and only if the prior distribution of agents’ types satisfies … the Coalition Beliefs Determine Preferences (CBDP) property. When the CBDP property holds, these mechanisms can be …

We propose a framework to analyze coalition formation with heterogeneous agents. Existing literature defines stability … conditions that do not ensure that, once an agent decides to sign an agreement, the enlarged coalition is feasible. Defining the … concepts of refraction and exchanging, we set up conditions of existence and enlargement of a coalition with heterogeneous …

2100. Once the free-riding incentives of non-participants are taken into account, only a “grand coalition” including … virtually all regions can be successful. This grand coalition is profitable as a whole, implying that all countries can gain … from participation provided appropriate transfers are made across them.
