Information within coalitions: risk and ambiguity

Listed author(s):
  • Emma Moreno-García
  • Juan Pablo Torres-Martínez

We address economies with asymmetric information where agents are not perfectly aware about the informational structure for coalitions. Thus, we introduce solutions that we refer to as risky core and ambiguous core. We provide existence results and a variety of properties of these cooperative solutions.
