产业集群内企业之间合作创新的理论分析

集群有利于降低合作创新的交易成本、获得合作伙伴的隐性知识.企业选择合作创新,其动机主要是解决技术的外部性、分担研究开发成本和风险、获得合作伙伴的缄默性知识、实现技术转移以及获得巨大的国内和国际市场等.对合作创新的博弈分析表明,企业要形成合作创新的联盟,该联盟必须满足超可加性;否则,其成员没有动机形成联盟,已经形成的联盟也将面临解散的威胁.合理的利益分配方案是合作创新的基础.该方案是合作各方讨价还价的结果.     

Component efficient solutions in line-graph games with applications

Recently, applications of cooperative game theory to economic allocation problems have gained popularity. We investigate a class of cooperative games that generalizes some economic applications with a similar structure. These are the so-called line-graph games being cooperative TU-games in which the players are linearly ordered. Examples of situations that can be modeled like this are sequencing situations and water distribution problems. We define four properties with respect to deleting edges that each selects a unique component efficient solution on the class of line-graph games. We interpret these solutions and properties in terms of dividend distributions, and apply them to economic situations. This research has been done while the third author was visiting Tinbergen Institute at the Free University, Amsterdam. The research is part of the Research Programme “Strategic and Cooperative Decision Making” at the Department of Econometrics. Financial support from the Netherlands Organization for Scientific Research (NWO) in the framework of the Russian-Dutch programme for scientific cooperation, is gratefully acknowledged. The third author also appreciates partial financial support from the Russian Leading Scientific Schools Fund (grant 80.2003.6) and Russian Humanitarian Scientific Fund (grant 02-02-00189a).

A Suggested Interpretation of Some Experimental Results on Preplay Communication

M. Rabin (1994, J. Econ. Theory63, 370-391) proposes a model of behavior in two-person complete-information games with preplay communication, using non-equilibrium notions in the spirit of rationalizability to derive lower bounds on players' expected payoffs when players have unlimited communication opportunities. This paper adapts Rabin's model so that it can be used to analyze the results of the experiments of R. Cooper et al. (1989, Rand J. Econ.20, 568-587) on structured preplay communication in the Battle of the Sexes and the results of the unstructured bargaining experiments of Roth, Malouf, and Murnighan. Adding empirically motivated restrictions that allow the model to predict the payoff effects of changes in bounded communication possibilities like those in the experiments, it is shown that the data from both experiments are generally consistent with Rabin's model, and with the predictions of the extended model.

食品供应链安全问题的信号博弈模型

基于食品供应链上安全信息不对称的特点以及零售企业运营状况,针对滥用食品安全标签(如无公害、绿色、有机食品标签等)的现象,以食品生产商和消费者作为博弈方,建立信号博弈模型,分析信号博弈的三种贝叶斯均衡及其条件,得出了信息不对称情况下安全食品生产商的损失函数,以及政府控制食品安全的策略。     

具缺货期不同决策支配权的两级供应链合作机制研究

从考虑市场需求固定且卖方和买方对缺货期的不同决策支配权情况,研究了两级供应链的合作机制,建立了其不完全信息的动态博弈模型,并得出其精炼贝叶斯纳什均衡,从理论上证明了卖方和买方分别占支配地位和从属地位时买方卖方应相互合作。     

中小企业研发困境的博弈分析

知识经济时代，企业自主研发是增强其竞争力的必经途径。而在国内，众多中小企业对研发投入持消极态度，尽管政府多方鼓励，但收效不大，且企业在自主研发的投入方面与发达国家有着较大的差距。可从严格保护研发成果、协作研发与加大政府的政策优惠力度等方面对中国中小企业的研发投入情况进行改进。     

Low information nash equilibria for oligopolistic markets

This paper deals with an infinite horizon n firm oligopoly in which firms are assumed to have incomplete information about one another's actions and profit functions. An equilibrium concept is defined that is similar to the Nash non-cooperative equilibrium, but is suitable for the information assumptions of the model. The equilibrium uses a type of bounded rationality which makes firms' computations relatively easy. This is due to an implicit assumption that computation is costly and a Bayesian approach is prohibitively costly. This low information Nash equilibrium is proved to exist, and, in addition, an adaptive expectations decision process is described which, if followed by all firms, leads to the low information Nash equilibrium.     

Managing the international commons: Resource use and pollution control

The simultaneous management, in an international context, of free-access renewable resources and transboundary pollution, is examined in a dynamic game framework. First-best outcomes under international cooperation are determined and compared to noncooperative outcomes when countries follow linear Markov strategies. An international policy consisting of taxes on emissions and harvesting, with international redistribution of tax receipts, is used to achieve the cooperative solution. In addition, side payments may be required to prevent free riding and thus make the international policy implementable.Earlier versions of this paper were presented at the International WorkshopEconomic Aspects of International Water Resources Utilization in the Mediterranean Basin, Fondazione ENI Enrico Mattei, Milan, October 1993, and the Fifth Annual Conference of EAERE, Dublin, June 1994.

一种项目采购模式的博弈分析

本文试图用经济学理论 (主要是博弈与信息经济学的理论 )来分析目前工程项目建设中采用的一种工程设备、材料的采购模式。文章首先提出这种模式的内容与特征 ,然后就制度内各参与方 (主要为业主、承包商、供货商 )之间的博弈进行分析 ,分不完全信息博弈、完全信息博弈两种情况来分析这种采购制度下达到的均衡。
