房地产市场价格博弈分析

我国房地产业发展迅速,房地产市场的发展对促进国民经济发展做出了突出贡献,房地产业已成为我国重要支柱产业之一.我国房地产市场现状是博弈得出结果的一个竞技场.文章从房地产销售过程中主要参与者的价格博弈分析,探究房地产市场交易价格形成的过程,指出中国房地产业的现状是由社会几股力量反复博弈的结果,其实质是不同社会力量之间的利益之争.     

Regional Planning of Wastewater Reuse for Irrigation and River Rehabilitation

Subject to a few agri‐environmental restrictions, municipal wastewater can be utilised for agricultural irrigation and river rehabilitation. This paper develops a single‐year Planning Model for a region in Israel which consists of a city and three potential wastewater consumers. The model incorporates, in one endogenous system, the economic, physical and biological relationships in the water–soil–plant–environment system and its objective is to maximise the regional social welfare. The model determines the optimal crop mix and the optimal allocation of the limited water and land resources among all potential users. Then, different allocation approaches from the concept of transferable utility games are applied to determine a reasonable and fair allocation of the additional net benefits which will be acceptable to all the players. The results support the collaboration among the economic entities and indicate economic and environmental advantages which can serve the decision‐makers.     

区域产业集群多企业间合作性交易的激励

本文运用重复博弈理论分析区域产业集群内多企业间合作性交易过程发现,当集群内形成第三方激励组织对企业间不合作行为惩罚大到永誓不会交易,甚至会被赶出集群时,就能激励集群内企业间合作从两企业向多企业合作发展。分析温州产业集群内商会组织发现,该组织能有效地监督集群内交易企业潜在的不诚实行为,为交易方提供一个合作激励机制,激励集群内多企业间的交易从欺骗均衡转到合作均衡,提升了集群的绩效和整体竞争力。     

景区门票价格偏高的一个博弈论解释

指出景区产品是差别垄断产品，通过引入博弈论的思想，论证差别垄断这一特性可能使得景区自动趋向完全垄断价格，造成社会福利损失。这一模型可以解释我国门票价格偏高以及部分景点还在酝酿提价的现象。     

Beliefs and rationalizability in games with complementarities

We propose two characteristics of beliefs and study their role in shaping the set of rationalizable strategy profiles in games with incomplete information. The first characteristic, type-sensitivity, is related to how informative a player thinks his type is. The second characteristic, optimism, is related to how “favorable” a player expects the outcome of the game to be. The paper has two main results: the first result provides an upper bound on the size of the set of rationalizable strategy profiles; the second gives a lower bound on the change of location of this set. These bounds are explicit expressions that involve type-sensitivity, optimism, and payoff characteristics. Our results generalize and clarify the well-known uniqueness result of global games (Carlsson and van Damme, 1993). They also imply new uniqueness results and allow us to study rationalizability in new environments. We provide applications to supermodular mechanism design (Mathevet, 2010b) and information processing errors.     

Cournot Competition and Hit-and-Run Entry and Exit in a Teaching Experiment

Instructors can use a computerized experiment to introduce students to imperfect competition in courses on introductory economics, industrial organization, game theory, and strategy and management. In addition to introducing students to strategic thinking in general, the experiment serves to demonstrate that profits of a firm fall as the number of competitors is increased in a market and that firms enter profitable markets. The authors have used the experiment in undergraduate classes on strategy and management as well as in master of business administration courses with great success.     

Learning by Trial and Error: A Case for Moot Courts

This article describes the development of a computer tutorial for use in a history of economic ideas class. An early version of the tutorial contained ten topics, ranging from early Mercantilist thought to Jevons's marginal utility analysis. These concepts were presented in three ways: verbally, graphically, and in summary form. Student critiques were used to extend the content and revise the mode of presentation.     

Strategic behavior in financial markets

We describe a financial market as a noncooperative game in strategic form. Agents may borrow or deposit money at a central bank and use the cash available to them in order to purchase a commodity for immediate consumption. They derive positive utility from consumption and from having cash reserves at the end of the day, whereas being bankrupt entails negative utility. The bank fixes interest rates. The existence of Nash equilibria (both mixed and pure) of the ensuing game is proved under various assumptions. In particular, no agent is bankrupt at equilibrium. Asymptotic behavior of replica markets is discussed, and it is shown that given appropriate assumptions, the difference between a strategic player and a price taker is negligible in a large economy.
