This paper studies the formation of international climate coalitions by heterogeneous countries. Countries rationally predict the consequences of their membership decisions in climate negotiations. We offer an approach to characterise the equilibrium number of coalitions and their number of...

Several recent studies find that interventions in schools can have important lasting consequences for students, and that schools differ in their contribution to students’ learning. However, there is less research investigating how these differences between schools influence longer-term...

This paper studies an exchange economy with a finite number of agents in which each agent is initially endowed with a finite number of (personalized) indivisible commodities. We observe that the core equivalence theorem may not hold for this economy when the coalitional form game is generated in...

We design a laboratory experiment to identify whether a preference for randomization defines a stable type across different choice environments. In games and individual decisions, subjects face twenty simultaneous repetitions of the same choice. Subjects can randomize by making different choices...

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...
