The Robustness of Equilibria to Incomplete Information

A number of papers have shown that a strict Nash equilibrium action profile of a game may never be played if there is a small amount of incomplete information. The authors present a general approach… Expand

Constrained suboptimality in incomplete markets: a general approach and two applications

- A. Citanna, A. Kajii, Antonio Villanacci
- Economics
- 29 May 1998

Summary. In this paper we re-examine generic constrained suboptimality of equilibrium allocations with incomplete numeraire asset markets. We provide a general framework which is capable of resolving… Expand

Intrinsic Preference for Information

Suppose, following Kreps & Porteus (1978), that an agent values information not only to make contingent plans but also for itself; that is, intrinsically. What, then, is the relationship between an… Expand

PAYOFF CONTINUITY IN INCOMPLETE INFORMATION GAMES

Abstract An incomplete information game is defined by a probability distributionμover a type space and payoff functionsu. Probability distributionμ′ isstrategically closetoμif, for any bounded payoff… Expand

Incomplete Information Games with Multiple Priors

We present a model of incomplete information games with sets of priors. Upon arrival of private information, each player "updates" by the Bayes rule each of priors in this set to construct the set of… Expand

A generalization of Scarf's theorem: An α-core existence theorem without transitivity or completeness

- A. Kajii
- Mathematics
- 1 February 1992

Abstract Consider an n-person non-cooperative game. A coalition is said to α-block a given social state if it has a feasible strategy with which the coalition can ensure a social state preferred by… Expand

Refinements and Higher Order Beliefs: A Unified Survey

This paper presents a simple framework that allows us to survey and relate some different strands of the game theory literature. We describe a "canonical" way of adding incomplete information to a… Expand

Ausi Expected Utility: An Anticipated Utility Theory of Relative Disappointment Aversion

In recent years there has been a growing theoretical, experimental and empirical challenge to Expected Utility Theory, the overwhelmingly dominant paradigm for modeling decision-making under risk.… Expand

Temporal Resolution of Uncertainty and Recursive Non‐expected Utility Models

If an agent (wealkly) prefers early resolution of uncertainty then the recursive forms of both the most commonly used non-expected utility models, betweenness and rank dependence, almost reduce to… Expand

How to discard non-satiation and free-disposal with paper money

- A. Kajii
- Economics
- 1996

Abstract It is well known that a competitive equilibrium may fail to exist when preferences are possibly satiated. We show that this non-existence problem does not arise if one of the commodities is… Expand
