Biform Games (2007, background): “49Ghirardato (2001) obtains a similar representation. He starts with a state-space formulation, but then coarsens the decision maker’s perception of the state space. Nehring and Puppe (1996) present conditions under which preferences over sets depend on the maximal and minimal elements of the sets.”
Types of Uncertainty (2014, background): “by what Ghirardato (2001) terms a correspondence from states into sets of consequences.”
Decision theory under ambiguity (2012, unknown): “is characterized then by the shape of the utility function u and ambiguity aversion, in the sense of Ghirardato and Marinacci (2002), by the shape of Φ.”
Random Correspondences as Bundles of Random Variables (2001, background): “to model unforeseen contingencies and preference for flexibility by Mukerji (1997), Nehring (1999), Ghirardato (2001), and Ozdenoren (2002).”
Ambiguity without a state space (2004, background): “Finally, Ghirardato (2001), Jaffray and Jeleva (2004), Mukerji (1997), and Nehring (1999) consider multi-valued acts which map states of the world to sets of consequences, while Viero (2006) considers acts which map to sets of lotteries.”
Optimal risk-sharing rules and equilibria with Choquet-expected-utility (2000, unknown): “More generally, in the case of probabilized risk, Landsberger and Meilijson [1994] and Chateauneuf, Cohen and Kast [1997] have shown that Pareto Optima (P.”
