投资者关系管理的博弈分析

本文主要从三个角度论述上市公司投资者关系管理的博弈分析,即投资者与上市公司之间的非合作博弈、机构投资者与个人投资者之间的“智猪博弈”以及投资者与上市公司之间的合作博弈。阐明投资者与上市公司非合作博弈的严重后果,机构投资者在促使上市公司实施投资者关系管理方面的作用,以及上市公司实施有效的投资者关系管理后的“双赢”结果。     

Melioration learning in games with constant and frequency-dependent pay-offs

The paper explores the implications of melioration learning—an empirically significant variant of reinforcement learning—for game theory. We show that in games with invariable pay-offs melioration learning converges to Nash equilibria in a way similar to the replicator dynamics. Since melioration learning is known to deviate from optimizing behavior when an action’s rewards decrease with increasing relative frequency of that action, we also investigate an example of a game with frequency-dependent pay-offs. Interactive melioration learning is then still appropriately described by the replicator dynamics, but it indeed deviates from rational choice behavior in such a game.     

Laws of scarcity for a finite game - exact bounds on estimations

Summary. A law of scarcity is that scarceness is rewarded. We demonstrate laws of scarcity for cores and approximate cores of games. Furthermore, we show that equal treatment core payoff vectors satisfy a condition of cyclic monotonicity. Our results are developed for parameterized collections of games and exact bounds on the maximum possible deviation of approximate core payoff vectors from satisfying a law of scarcity are stated in terms of the parameters describing the games. We note that the parameters can, in principle, be estimated.Received: 21 November 2002, Revised: 7 October 2003, JEL Classification Numbers: C71, C78, D41.

一种新的边缘经济理论--量子博弈论

博弈论作为在应用数学中具有重要应用价值的一个分支,在信息科学、进化生物学、社会科学等诸多学科中有着广泛的应用.将量子理论方法引入经典博弈中的决策过程,就形成了一个新兴的科学领域--量子博弈.经典博弈中存在的一些困境和悖论,在量子化后得以解决,而且在量子的体系下博弈展现出许多新的特征.     

The Value of Clean Air in China： Evidence from Beijing and Shanghai

We estimate the willingness to pay （WTP） of Beijing and Shanghai residents for improving the air quality of the two cities from their levels prior to the 2008 Beijing Olympic Games to the level achieved during the Olympics. The data are obtained from a contingent valuation study conducted through face-to-face interviews in June 2008 in Beijing and Shanghai prior to the Beijing Olympics, during which time there was intensive debate about Beijing＇s air quality. Residents in both cities are willing to pay more when they are more exposed to air pollution, when their disposable income increases, and when they have stronger beliefs that public opinion plays an important role in government policy making. Beijing residents are willing to pay more than Shanghai residents, due possibly to Beijing＇s poorer air quality. Overall, aggregate WTP for air quality improvement accounts for about 0.53% of the 2008 GDP in Beijing and 0.22% of the 2008 GDP in Shanghai.     

一带一路背景下基础设施PPP项目风险分担研究

一带一路PPP项目面临着巨大的风险,项目成功与否的决定性因素是风险的合理分担,不合理的风险分担会影响项目参与者的积极性,有损项目整体收益。在PPP项目风险分担原则的基础上,将风险分为自担风险和共担风险,运用随机合作博弈模型确定双方共担风险的分担比例。通过建立一带一路PPP项目风险分担模型,实现一带一路PPP项目最优风险策略组合。     

试析2010年亚运会对广州旅游业的影响和对策

2010年亚运会主办城市归属中国广州,其蕴涵影响深远。广州亚运会既是广州旅游业发展的最大契机,也是广州城市发展进程中难得的一次历史机遇。广州应通过亚运会这一高端平台,向世界全面展现其形象与素质、经济实力、旅游吸引力与文化魅力,提升城市的竞争力。广州要抓住这一机遇,最大程度的提升广州国际化知名度和影响力,塑造国际化旅游城市的新形象。要充分利用广州的旅游资源及地域特点,拓展多种形式的旅游产品,关注后亚运效应,增强亚运旅游资源的持续利用,使广州市旅游业实现跨越式发展。
