In the Colonel Blotto game, two players simultaneously distribute forces across n battlefields. Within each battlefield, the player that allocates the higher level of force wins. The payoff of the game is the proportion of wins on the individual battlefields. An equilibrium of the Colonel Blotto game is a pair of n-variate distributions. This paper characterizes the unique equilibrium payoffs for all (symmetric and asymmetric) configurations of the players’ aggregate levels of force, characterizes the complete set of equilibrium univariate marginal distributions for most of these configurations, and constructs entirely new and novel equilibrium n-variate distributions.I am grateful to Jason Abrevaya, Dan Kovenock, James C. Moore, Roger B. Nelsen, and three anonymous referees for very helpful comments. A version of this paper was presented at the 2005 Midwest Economic Theory Meetings. This paper is based on the first chapter of my Ph.D. dissertation 相似文献

We examine a multi-dimensional incomplete information Colonel Blotto game in which each player’s n-tuple of battlefield valuations is drawn from a common n-variate joint distribution function that is uniform on the non-negative orthant of the surface of a sphere. 相似文献

This paper provides a model that attempts to deal with the transboundary nature of the acid rain problem, using a game theoretic approach consistent with mainstream economic theory. The general forms of cooperative and non cooperative equilibria in explicit and implicit set-up of the model are presented under the assumptions of complete and incomplete information. 相似文献

不完全信息、反倾销威胁与最优出口贸易政策 总被引:3,自引:0,他引:3
通过扩展Brander和Spencer(1985)的基本模型,本文首先证明了,在反倾销威胁下,基于完全信息假设的最优出口贸易政策要求出口国政府给予低成本企业更高的出口补贴或更低的出口征税,在无效激励机制下必然导致出口企业隐匿自己的真实成本类型,基于完全信息假设的最优出口贸易政策失效。在此基础上,本文进一步论证了不完全信息和反倾销威胁下激励相容的最优出口贸易政策,该政策要求出口国政府依据进口国国内要求保护压力的大小,采用不同的出口征税和一次性转移支付政策组合,激励出口企业如实报告成本类型,并使国家整体福利最大化。 相似文献

We experimentally investigate if free information disadvantages a player relative to when information is unavailable. We study
an Ultimatum game where the Proposer, before making an offer, can obtain free information about the Responder's minimum acceptable
offer. Theoretically, the Proposer should obtain the information and play a best reply to the Responder's minimum acceptable
offer. Thus the Responder should get the largest share of the surplus. We find that an increasing number of Proposers become
informed over time. Moreover, the proportion of Proposers who use the information to maximize money earnings increases over
time. The majority of information-acquiring Proposers, however, refuse to offer more than one-half and play a best reply only
to Responders who accept offers of one-half or less. This, together with a substantial proportion of Proposers who choose
to remain uninformed, means that the availability of free information backfires for Proposers only by a little.

本文针对三度价格歧视存在信息不对称的问题,讨论了两个寡头垄断企业在成本信息不对称的情况下,在两个细分市场实施价格歧视的产量决策问题.将成本函数分为三种、两种及一种可选成本(完全信息)3类情况,通过海萨尼转换,根据成本甄别系数的不同取值范围,得出了两个寡头垄断企业相互制约下的均衡产量、均衡价格、均衡利润及相互关系.研究结果表明:成本甄别系数越小,成本信息劣势企业的均衡产量越高,均衡状态下的总利润也越高;当寡头垄断企业1采用较高成本时,企业1会更加倾向于隐藏自身成本,他在具有信息优势的同时还具有成本劣势;而当寡头垄断企业1采用低成本时,则不会隐藏自己的信息而更倾向通过信号传递,把低成本信息的优势传递出去,以使寡头垄断企业2按完全信息决策产量等结论.本文的研究结果将为信息不对称下的歧视定价提供理论依据. 相似文献

不完全契约理论:一个综述 总被引:89,自引:3,他引:89
标准的契约理论或委托-代理理论假定契约是完全的,然而现实中的契约是不完全的。契约的不完全会导致事前的最优契约失效,当事人在面临被“敲竹杠”的风险时会做出无效率的专用性投资。经济学家们在研究如何最大程度地减少由于契约不完全所导致的效率损失时,发展了一个新兴的不完全契约理论。本文以一个基本模型为基点,围绕专用性投资效率问题,从司法干预、赔偿、治理结构、产权以及履约等多个视角,全面地介绍了不完全契约理论的产生、发展、应用以及面临的挑战和未来的前景。 相似文献

This paper presents an incomplete information model, where a supervisor is entrusted with supervising a number of potential criminals of different types. The supervisor may not know the type of an individual criminal. We show how lack of complete information available to the law-enforcing agent may help to prevent crime at least to a limited extent by making rewards and penalties more effective. 相似文献

To any assignment market we associate the unique exact assignment game defined on the same set of agents and with a core that is a translation of the core of the initial market. As it happens with the core, the kernel and the nucleolus of an assignment game are proved to be the translation of the kernel and the nucleolus of its related exact assignment game by the vector of minimum core payoffs. Agents on each side of the market are classified by means of an equivalence relation and, when agents on the same class are ordered to be consecutive, the related exact assignment market is defined by a partitioned matrix, each block of the partition being a glove market. 相似文献

不完全合同理论的新视角——基于演化经济学的分析 总被引:5,自引:0,他引:5
长期以来,主流不完全合同理论一直没有在理论逻辑上圆满解答"合同为什么不完全",其理论基础存在很大的争议,这也导致其研究范式存在内在的逻辑矛盾与冲突,大量有关不完全合同的研究本质上却是关注完全合同。本文尝试从演化经济学的视角重新审视不完全合同理论,强调必须从知识不完全性的视角来阐释合同的不完全性,认为个体的有限认知是合同不完全性的重要理论基础,在此视角下探讨了不完全合同的功能、生成及其演变,并重新考察了权威在不完全合同中的作用。 相似文献

We address the questions of the patterns and the efficiency of public intervention in a dynamic game model between public agencies in charge of a non-local externality. We give two examples: pollution spreading between water basins (negative externality), and non-uniform contributions from the elite and from the mass to a cultural background (positive externality). We define two extreme cases, depending on whether or not the receiving end of the externality balances the transmitting end. When both balance, the reactivity of the agency structure is strong and the need for redistribution between them is weak. When they do not balance, the externality is more markedly non-local and redistribution is required to balance the fiscal burden (or product) from pigouvian instruments among all beneficiaries. We show that, with a static rule of redistribution that allows them to compute transfers between them as a function of their own strategies, the decentralized agencies' reactivity is somewhat slowed, but they still react faster and more efficiently than a static central agency. 相似文献

Summary. In a multiperiod economy with incomplete markets and assets with payoff depending on the price history (e.g., asset and derivatives),
we show that in order to get endowment generic existence of an equilibrium it is not needed to alter settlement features such
as when payments are made and when the asset is traded. This is non-trivial as each such characteristic introduces a non-generic
subclass of financial instruments. We show essentially that expiry date payments are the only payments that one needs perturbing
(if at all). For previous periods - the P&L discovery map - is the one relevant for wealth transfers. This map transfers wealth
between one period and the next by associating to each portfolio next period potential profit and losses as a function of
the revealed information at the node. All present values involved can in general - because of backward induction pricing structure
- be appropriately controlled via expiry payoffs only. This enables us to extend two-period work and introduce Transverse
Financial Structures for multiperiod economies, where one cannot identify the payoffs of financial instruments to the P&L
discovery map (in other words we introduce some financial ingeneering for Transverse Financial Structures). We capitalize
on that difference using unexploited “maturity payout degrees of freedom” and rolling back the uncertainty tree. As an application
of this approach we prove a conjecture by Magill and Quinzii that commodity forward contracts lead to endowment generic existence
of an equilibrium in a multiperiod set-up.

I study alternating-offer bargaining games with two-sided incomplete information about the players' discount rates. For both perfect Bayesian equilibrium and a rationalizability-style notion, I characterize the set of expected payoffs which may arise in the game. I also construct bounds on agreements that may be made. The set of expected payoffs is easy to compute and incorporate into applied models. My main result is a full characterization of the set of perfect Bayesian equilibrium payoffs for games in which the distribution over the players' discount rates is of wide support, yet is in a weak sense close to a point mass distribution. I prove a lopsided convergence result: each player cannot gain from a slight chance that she is a strong type, but the player can suffer greatly if there is a slight chance that she is a weak type. 相似文献

Incomplete preferences and rational intransitivity of choice 总被引:3,自引:1,他引:3
Michael Mandler 《Games and Economic Behavior》2005,50(2):255-277
Do violations of classical rationality theory imply that agents are acting against their self-interest? To answer this question, we investigate whether completeness and transitivity necessarily hold when agents choose outcome rationally—that is, their choice sequences do not lead to dominated outcomes. We show that, because of the danger of money pumps and other manipulations, outcome rationality implies that agents must have transitive psychological preferences. Revealed preferences, on the other hand, must be complete since agents can be forced to choose from any set of options. But these justifications of transitivity and completeness cannot be combined. We show that if psychological preferences are incomplete then revealed preferences can be intransitive without exposing agents to manipulations or violating outcome rationality. We also show that a specific case of nonstandard behavior, status quo maintenance, is outcome-rational in the simple environments considered in the experimental literature, but not in more complex settings. 相似文献

We consider two-person non-zero-sum infinitely repeated games with lack of information on one side. The characterization of Nash equilibrium payoffs obtained by Hart allows for complex strategies, which are actually required by some equilibrium payoffs in some games. We show that appropriate one-shot public communication mechanisms make Nash equilibrium payoffs achievable by means of simple strategies. Furthermore, these mechanisms satisfy a notion of self-fulfillment.Journal of Economic LiteratureClassification Numbers: D82, C72. 相似文献

In contrast with what we perceive is the conventional wisdom about setting a second-best emissions tax to control a uniformly
mixed pollutant under uncertainty, we demonstrate that setting a uniform tax equal to expected marginal damage is not generally
efficient under incomplete information about firms’ abatement costs and damages from pollution. We show that efficient taxes
will deviate from expected marginal damage if marginal damage is increasing and there is uncertainty about the slopes of the
marginal abatement costs of regulated firms. Moreover, tax rates will vary across firms if a regulator can use observable
firm-level characteristics to gain some information about how the firms’ marginal abatement costs vary. 相似文献
