In repeated games with public monitoring, the consideration of behavior strategies makes relevant the distinction between public and private strategies. Recently, Kandori and Obara [5] and Mailath, Matthews and Sekiguchi [7] have provided examples of games with equilibrium payoffs in private...

In each stage of a repeated game with private monitoring, the players receive payoffs and privately observe signals which depend on the players' actions and the state of world. I show that, contrary to a widely held belief, such games admit a recursive structure. More precisely, I construct a...

We focus on a class of Multiple Prior Models. Those characterized by nonatomic countably additive priors. Preferences generating such representations have been recently axiomatized in [17]. We argue that this is the proper setting for comparing the notions of unambiguous event given by Epstein...

The paper provides a notion of measurability which is suited for a class of Multiple Prior Models. Those characterized by nonatomic countably additive priors. Preferences generating such representations have been recently axiomatized in [12]. A notable feature of our definition of measurability...

Cr¨¦mer and McLean [1] and McAfee and Reny [3] showed that, in "nearly all auctions", the seller can offer a mechanism that obtains full rent extraction. The mechanism designed by Cr¨¦mer and McLean differs from standard procedures in several respects. Notably, (a) bidders are required to...

Crer and McLean [2] and McAfee and Reny [4] showed that, in "nearly all auctions", the seller can offer a mechanism that obtains full rent extraction. Later, Robert [8] showed that the result fails in the presence of either limited liability or risk aversion. This paper provides yet another...

We give a definition of reasoning by analogy, which is tailored to a setting of decision making under uncertainty. We present a model of decision making which is based on such a definition, and show that it is compatible with a large class of preferences

We provide an alternative proof of a theorem of Marinacci [2] regarding the equality of two convex-ranged measures. Specifically, we show that, if P and Q are two nonatomic, countably additive probabilities on a measurable space (S, S), the condition [A* S with 0 < P(A*) < 1 such that P(A*) = P(B)=> Q(A*) = Q(B) whenever B?S] is...</p(a*)>

For (S, S) a measurable space, let C1 and C2 and be convex, weak* closed sets of probability measures on S. We show that if C1 C2 satisfies the Lyapunov property, then there exists a set A S such that min C1 (A) max C2 (A). We give applications to Maxmin Expected Utility and to the core of a...
