The emergence and survival of cooperation is one of the hardest problems still open in science. Several factors such as the existence of punishment, repeated interactions, topological effects and the formation of prestige may all contribute to explain the counter-intuitive prevalence of...

In this paper, we present a general model in which mutually dependent negotiations are simultaneously conducted and define a solution concept for the model. We provide a sufficient condition for the solution to exist and show that the solutions approximately coincide with the equilibrium...

Using an updated version of the CWS model (introduced by Eyckmans and Tulkens in Resource and Energy Economics 2003), this paper intends to evaluate with numbers the respective merits of two competing notions of coalition stability in the standard global public goods model as customarily applied...

This work shows that defective behaviors from the cooperative equilibrium in the management of common resources can be fueled and triggered by the presence of agents with myopic behaviors. The behavior implemented by naïve agents, even if performed with cooperative intent, can activate a...

Why do coalitions of people or firms stay intact overtime in some situations, while in other situations the size and members of the coalitions change frequently? This paper develops a framework based on dynamic hedonic games, a special class of cooperative games, to find conditions for the...

There is continuing debate about what explains cooperation and self-sacrifice in nature and in particular in humans. This paper suggests a new way to think about this famous problem. I argue that, for an evolutionary biologist as well as a quantitative social scientist, the triangle of two...

We introduce a new class of cooperative games where the worth of a coalition depends on the behavior of other players and on the state of nature as well. We allow for coalitions to form both before and after the resolution of uncertainty, hence agreements must be stable against both types of...

In the beginning of the second book of his Politeia (Republic) Plato in passage 2.358e-359a-c raises the issue of the administration of justice as a means of motivating people to behave fairly regarding their relationships and when cooperating with each other because, at the end, this is...

This report provides a conceptual foundation for the analysis of international regulatory co-operation (IRC) and its potential benefits through reduced trade costs. Different forms of IRC aiming to reduce specification, conformity assessment and information costs - which can arise from...

Group tasks are often organized by a list: group members state their willingness to contribute by entering their names on a publicly visible, empty list. Alternatively, one could organize the group task by starting with a full list: every group member is already entered on the list and...
