We study the formation of coalitions that provide public goods to members. Individuals are linked on a tree graph and those with similar preferences are connected on the tree. We present a solution that selects allocations belonging to the coalition structure core and that are also envy-free.

We offer a model in which sequences of individuals often converge upon poor decisions and are prone to fads, despite being able to communicate both past payoff outcomes and the private signals underlying past choices. This reflects direct and indirect action-based informational externalities;...

The recent literature on informational cascades has nurtured the impression that cascades can occur only if the action space is coarser than the signal space. In particular, it is sometimes claimed that with continuous action spaces cascades are impossible. In this note we present a simple...

We study Nash equilibria of joint production games under a mixed output sharing rule in which part of the output (the mixing parameter) is shared in proportion to inputs and the rest according to exogenously determined shares. This rule includes proportional sharing and equal sharing as special...

In this paper we consider the way in which authorities arise in response to the need for coordination. In a model of local interaction, an authority is understood as a self-enforcing coordination selection structure, where the threat of violence ensures compliance. Such authorities form if...

Current analysis addresses an apparently critical issue of wealth circulation in the society. In the form of three persons game, we put the welfare-related burden on taxpayers. The Negotiator No.1 stands up for citizens’ legal and moral right to social services. The Negotiator No.2 proceeds...

A profit-maximizing auctioneer can provide a public good to a group of agents. Each group member has a private value for the good being provided to the group. We investigate an auction mechanism where the auctioneer provides the good to the group, only if the sum of their bids exceeds a reserve...

It would be interesting and scientifically rewarding to investigate the possibilities of designing a "sheltered" situation room for the Information Technologies and Telecommunications services and products market. The proposed framework might be employed during any phase of the life cycle of an...
