Unicity of the equilibrium in the unconstrained Hotelling model

A spatial duopoly is described, where firms are free to locate along the real axis, while consumers are distributed along a linear city of finite length. By adding a preplay stage where firms are required to set the timing of moves, one can analyze issues such as the endogenous choice of roles and the nature of differentiation at equilibrium. The distribution of roles is discussed both at the location stage and at the price stage. The game exhibits a unique subgame perfect equilibrium in pure strategies (up to a permutation), where firms play simultaneously in locations and sequentially in prices. Moreover, the results highlight the relevance of endogenous differentiation in altering some of the conclusions reached by previous literature. Finally, it turns out that the nature of differentiation may be heavily affected by the sequence of decisions.

Existence of an equilibrium for infinite horizon economies with and without complete information

This work proves the existence of an equilibrium for an infinite horizon economy where trade takes place sequentially over time. There exist two types of agents: the first correctly anticipates all future contingent endogenous variables with complete information as in Radner [Radner, R. (1972). Existence of equilibrium of plans, prices and price expectations in a sequence of markets. Econometrica, 289–303] and the second has exogenous expectations about the future environment as in Grandmont [Grandmont, J. M. (1977). Temporary general equilibrium theory. Econometrica, 535–572] and information based on the current and past aggregate variables including those which are private knowledge. Agents with exogenous expectations may have inconsistent optimal plans but have predictive beliefs in the context of Blackwell and Dubbins [Blackwell, D., Dubins, L. (1962). Merging of opinions with increasing information. The Annals of Mathematical Statistics, 882–886] with probability transition rules based on all observed variables. We provide examples of this framework applied to models of differential information and environments exhibiting results of market selection and convergence of an equilibrium. The existence result can be used to conclude that, by adding the continuity assumption on the probability transition rules, we obtain the existence of an equilibrium for some models of differential information and incomplete markets.     

完全信息动态条件下企业总成本领先战略探究

首先,从迈克尔.波特教授的著作中引入总成本领先战略;接着,从博弈论斯坦克尔伯格模型出发,来建立所要分析问题的一般化模型,并分析一般化的完全信息动态模型得到均衡解。在结论分析中,引入要讨论的总成本领先战略,通过对比分析先动的企业和跟随的企业在采取成本领先的时候其市场的份额和利润,得到讨论的结论;先动的企业采取成本领先可以获得行业竞争优势,跟随企业在采取足够低的成本领先的前提下,也可以获得更高的市场份额和利润空间,从而可以获得竞争优势。     

不对称信息环境下企业诚信的博弈分析

经济社会要求企业必须做到诚信,但企业在现实的经营过程中,其表现往往是不诚信的。出现这一矛盾的根源,在于信息的不对称分布,本文通过建立企业诚信的一般博弈模型和重复博弈模型,讨论不对称信息环境下企业的行为选择,得出企业追求长期利益会导致诚信的结论。最后指出,企业要真正做到诚信,就要增加重复博弈的机会,变一次性博弈变成重复博弈。     

Learnability of an equilibrium with private information

This paper investigates the learnability of an equilibrium with private information. Agents of each type have their own private information about an exogenous variable and conduct adaptive learning with a heterogeneously misspecified perceived laws of motion (PLM) that includes only this variable. The paper shows that the existence of private information has a nonnegative impact on the learnability of the equilibrium; that is, the condition for learnability is unaffected or relaxed by heterogeneity and/or misspecification in PLMs caused by private information. In a New Keynesian model with private information about fundamental shocks, the learnability of the equilibrium is ensured by the Taylor principle of monetary policy. The paper also confirms that these results hold true not only in the presence of private information, but also in a variety of informational structures.     

Similarity of differential information with subjective prior beliefs

We present a complete, separable and metrizable topology on the product space of information and (subjective) beliefs. Such a topology formalizes similarity of differential information without the assumption of a common prior, but under the assumption that objectively impossible events are considered impossible by subjective beliefs. As an application to the theory of the consumer, we provide results on the continuity of expected utility and demand functions. We also provide continuity results for the value of information and the insurance premium as defined in the literature.     

A note on the equilibrium theory of economies with asymmetric information

In this note, we give an equilibrium existence theorem for exchange economies with asymmetric information and with an infinite dimensional commodity space. In our model, we assume that preferences are represented by well behaved utility functions, the positive cone has a non empty interior and the individual rational utility set is compact. Our result complements the corresponding one in Podczeck and Yannelis (2008), in the sense that is applicable to commodity spaces in which the order intervals are (possibly) not compact with respect to any Hausdorff linear topology.

New conditions for the existence of Radner equilibrium with infinitely many states

In atomless differential information economies, equilibria are known not to exist prevalently even when agents are risk averse expected utility maximizers. The notion of prevalence involves essentially picking an economy at random. In this paper, however, we establish existence results with economically meaningful assumptions on the information structure. We obtain existence when agents have independent information, and also when the total endowment of the economy is common knowledge.     

供应链中信息的共享对牛鞭效应的影响

本文用啤酒游戏的结果定性地比较分析信息共享对供应链中牛鞭效应影响,认为信息共享能够减少供应键中信息的波动和放大,但并不能消除供应链中的牛鞭效应,而且信息共享对供应链的上游比下游更为有利,因此供应链的上游应采取激励措施来促进信息的共享.

知识型客户关系管理中的信息技术应用研究

随着商业环境逐渐向知识密集型转变,知识管理在客户关系管理中的作用变得越来越重要,将知识管理应用于CRM(客户关系管理),使之具有知识性、分析性的特点,增强了企业对客户的识别、交流以及保持,同时信息技术的发展也为KCRM(知识型客户关系管理)的应用提供了技术上的保障和支持。因此探讨如何有效地将信息技术应用于KCRM,充分发挥KCRM对客户关系的管理,就显得十分有意义。     

基于供应商管理库存的信息系统设计研究

自从"零库存"的概念被丰田汽车公司提出以后,40多年来各生产企业绞尽脑汁考虑如何通过有效的运作与管理将库存降到最低.现在,供应商管理库存(VMI,Vendor Managed Inventory)的模式逐渐被国内企业接受.供应商管理库存,是在供应链管理理念下要求的产物。它要求供应商对下游企业库存策略、订货策略以及配送策略进行计划和管理。所以,采用合理模式运作VMI就成了当前要解决的问题。
