摘要：I define the largest consistent set, a solution concept which applies to situations in which coalitions freely form but cannot make binding contracts, act publicly, and are fully ''farsighted'' in that a coalition considers the possibility that, once it acts, another coalition might react, a third coalition might in turn react, and so on, without limit. I establish weak nonemptiness conditions and apply it to strategic and coalitional form games and majority rule voting. I argue that it improv...

摘要：This paper considers a profit maximizing monopolistic insurer who offers insurance to two types of risk averse agents in an environment where the uninsured position has the same distribution across types, agents' utility functions are private information, and types are independently and identically distributed. We prove that if there is no lower bound on liability and the types differ markedly in their attitudes to heavy losses, the insurer can extract almost all rent by offering full insuranc...

摘要：This note extends Haque's [J. Econ. Theory 25 (1981), 237-254] paper by (1) providing a closed-form characterisation of the conjunction of direct and indirect separability (and hence a closed-form characterisation of functions that are ''r-conditionally homogeneous of degree zero''), (2) characterising this separability condition in terms of the expenditure and distance functions as well as the direct and indirect utility functions, and (3) showing that Haque's partitioning of the commodity sp...

摘要：The papers in this symposium demonstrate the theoretical as well as the empirical plausibility of indeterminacy and of sunspots in equilibrium models with infinitely lived agents. They depart from the standard competitive framework because of the presence of externalities or of monopolistic competition. Some focus on business fluctuations while others address long-run growth. The second part of the Introduction presents a general unifying framework to identify the structure that is common to t...

摘要：Complicated equilibrium trajectories under least squared learning are shown to exist in a standard version of the overlapping generations model. These trajectories exist when the locally unique perfect foresight equilibrium is the monetary steady state, and thus are induced by the introduction of learning alone. This research confirms the intuition of some previous authors, who have suggested that stationary equilibrium trajectories under learning may differ from those under rational expectati...

摘要：Notions of input-neutral technical change and neutral productivity growth are compared and constrasted. Three natural conjugate ''neutrality pairs,'' each corresponding to a notion of input-neutral technical change and neutral productivity growth, are considered and their structural implications are deduced. Necessary and sufficient conditions for a technology to satisfy the various neutralities jointly are developed. (C) 1994 Academic Press, Inc.

摘要：A large decentralized market where buyers have private information about the idiosyncratic value of an exchange opportunity with a seller is studied. The seller offers the buyer a contract or mechanism as soon as he is matched. It is shown that if the discount factor is high enough, there will be a symmetric market equilibrium in which all sellers offer simple fixed price mechanisms. Along the equilibrium path these mechanisms will be ex ante inefficient. Prices will be too high and the extent...

摘要：The existence of ''speculative'' equilibria is proven in a simple overlapping generations, infinite horizon economy. In equilibrium, all agents bid for assets according to increasing functions of private information which is independent of the fundamental value (dividend stream) of the asset. This is a unique best response to the strategies of the other agents, which implies that speculative information is valuable. For certain stationary settings, the existence of speculative equilibria in wh...

摘要：An arbitrator faces the task of deciding the level of compensation to be received by a plaintiff from a defendant. The arbitrator must rely on the verifiable submissions of the two interested parties. Because the information of the interested parties is not verifiable, the ''unravelling argument'' has no force. Nevertheless, a class of equilibria of this game gives rise to a particularly simple decision rule for the arbitrator which appeals to a probability distribution over the payoff-relevan...

摘要：We characterize quasi-orderings on the power set of a set of alteratives. The subsets to be ranked are interpreted as opportunity sets available to an individual. The main criteria for ranking these opportunity sets are the individual preferences on the universal set of alteratives itself, and the freedom of choice associated with each subset of the universal set. This is reflected in the axioms used in the characterizations. (C) 1994 Academic Press, Inc.
