摘要：In the usual framework of continuum games with externalities, we substantially generalize Coumot-Nash existence results [Balder, A unifying approach to existence of Nash equilibria, Int. J.Game Theory 24 (1995) 79-94; On the existence of Cournot-Nash equilibria in continuum games, J. Math. Econ. 32 (1999) 207-223; A unifying pair of Cournot-Nash equilibrium existence results, J. Econ. Theory 102 (2002) 437-470] to games with possibly non-ordered preferences, providing a continuum analogue of t...

摘要：We consider a growth model proposed by Matsuyama [K. Matsuyama, Growing through cycles, Econometrica 67 (2) (1999) 335-347] in which two sources of economic growth are present: the mechanism of capital accumulation (Solow regime) and the process of technical change and innovations (Romer regime). We will shown that no stable cycle can exist, except for a fixed point and a cycle of period two. The Necessary and Sufficient conditions for regular or chaotic regimes are formulated. The bifurcation...

摘要：Who gains from stimulating output? We explore a dynamic model with production subsidies where the population is heterogeneous in one dimension: wealth. There are two channels through which production subsidies redistribute resources across the population. First, poorer agents gain from a rise in wages, since-to the extent there is an operative wealth effect in labor supply-they work harder. Second, because a current output boost will raise consumption today relative to the future, thus lowerin...

摘要：In a general-equilibrium economy with nonconvexities, there are sunspot equilibria with good welfare properties; sunspots can ameliorate the effects of the nonconvexities. For these economies, we show that agents act as if they have quasi-linear utility functions. We use this result to construct a new model of monetary exchange along the lines of Lagos and Wright. where trade occurs in both centralized and decentralized markets, but instead of quasi-linear preferences we assume general prefere...

摘要：Our objective is to assess whether dynamics hinder or assist co-ordination in a game with strategic complementarities. We study two dynamic aspects: different agents make decisions at different points in time; and extra information about a payoff-relevant state of nature becomes available over time. We find that the dynamic resolution of information matters most for uniqueness of equilibrium. This is demonstrated by showing that the condition for uniqueness is weaker when learning occurs. We a...

摘要：Parikh and Krasucki [R. Parikh, P. Krasucki, Communication, consensus and knowledge, J. Econ. Theory 52 (1990) 178-189] show that, in a group of rational agents, communication of the value of a function f leads to a consensus on the value of f, provided some conditions on the communication protocol and the function f hold. In this article, we address the issue of the influence of the protocol on the outcome of the communication process, when agents value information positively. We show that, i...

摘要：For impartial division, each participant reports only her opinion about the fair relative shares of the other participants, and this report has no effect on her own share. If a specific division is compatible with all reports, it is implemented. We propose a family of natural methods meeting these requirements, for a division among four or more participants. No such method exists for a division among three participants. (C) 2007 Elsevier Inc. All rights reserved.

摘要：In a principal-agent model with hidden information and no monetary transfers, I establish the veto-power principle: the principal can implement an optimal outcome through veto-based delegation with a properly chosen default decision. This result demonstrates the exact nature of commitment powers required by the principal: to design the default outcome and to ensure that she has almost no formal control over the agent's decisions.

摘要：This paper shows imperfect competition can lead to indeterminacy in aggregate output in a standard DSGE model with imperfect competition. Indeterminacy arises in the model from the composition of aggregate output. In sharp contrast to the indeterminacy literature pioneered by Benhabib and Farmer [J. Benhabib, R. Farmer, Indeterminacy and increasing returns, J. Econ. Theory 63 (1) (1994) 19-41] and Gali [J. Gali, Monopolistic competition, business cycles, and the composition of aggregate demand...

摘要：This paper introduces a new concept of full implementation that takes into account agents' preferences for understanding how the process concerning honest reporting works. We assume that the agents have intrinsic preferences for honesty in the sense that they dislike the idea of lying when it does not influence their welfare but instead goes against the intention of the central planner. We show that the presence of such preferences functions in eliminating unwanted equilibria from the practica...
