基于演化博弈的城市拆迁补偿机制研究

房屋动拆迁是我国城市建设与旧城改造中的重要环节,也是当前社会普遍关注的焦点。房屋动拆迁问题产生的重要原因在于补偿机制的不合理。本文引入演化博弈理论,建立城市拆迁补偿的演化博弈模型,分析不同收益值情况下的演化稳定策略,并针对当前拆迁补偿机制存在的漏洞,提出完善我国城市房屋拆迁补偿机制的政策建议。     

基于进化博弈的企业倾销与反倾销分析

基于博弈参与人的有限理性假设，文章通过运用进化博弈的分析工具，构建企业倾销与反倾销博弈的复制动态模型，以此得出结论：无论是面对国外对华反倾销，还是面对外国产品倾销，中国企业关键是实施自我保护战略，调整利益结构，以实现合作竞争。     

两型农业建设中相关利益主体间的博弈分析

资源节约型、环境友好型农业(简称两型农业)建设离不开政府(中央政府和地方政府)、涉农企业和农户。这个过程中也会产生委托—代理问题。基于利益相关者理论,深入分析中央与地方政府之间、地方政府之间、地方政府与涉农企业(农民)之间、涉农企业与农民之间、涉农企业(农民)之间的博弈行为。发展两型农业是利益主体之间动态博弈的结果,但是需要对地方政府、涉农企业和农户实施"引导"。这种"引导",可以使地方政府、涉农企业和农户有充分的信心选择两型生产。需要依靠加大投入力度、促进科技进步、建立科学的政绩评价体系和公众参与制度、加强行业自律和利益协调机制等办法来改进相关主体的博弈行为。     

Can Pokémon GO catch brands? The fit effect of game characters and brands on efficacy of brand communications

Given the recent popularity of augmented reality (AR) games, such as Pokémon GO, this study explores the congruence effect of game characters and brands on brand evaluations and the underlying mechanisms of the effect. Prior gaming experience and motivations are taken into account. An experiment reveals that inexperienced gamers are likely to have more favorable evaluations of the target brands when the images of game characters match the brand images, whereas these effects disappear for experienced gamers. Furthermore, the research demonstrates that experienced gamers are more likely to hold game-specific motivations than the inexperienced, while inexperienced gamers are motivated more by social interaction for playing AR games. Lastly, a mediation analysis reveals that social interaction-related motivation mediates inexperienced gamers’ preference of character–brand congruence. This study sheds light upon how AR games can be utilized by brand communicators.     

Asian option pricing with orthogonal polynomials

In this paper we derive a series expansion for the price of a continuously sampled arithmetic Asian option in the Black–Scholes setting. The expansion is based on polynomials that are orthogonal with respect to the log-normal distribution. All terms in the series are fully explicit and no numerical integration nor any special functions are involved. We provide sufficient conditions to guarantee convergence of the series. The moment indeterminacy of the log-normal distribution introduces an asymptotic bias in the series, however we show numerically that the bias can safely be ignored in practice.

Platform selection by software developers: Theory and evidence

This paper analyzes platform selection (affiliation) by game developers in the Japanese home video game industry. We develop an elementary model of affiliation by software developers and propose the hypothesis that wider availability of game titles for a platform positively inclines game developers to affiliate with that platform when releasing new game titles. Then, using data for Japan, we estimate a multinomial logit model that includes both the attributes of game developers and the characteristics of platforms, and find evidence supporting this hypothesis. Overall, the findings suggest that game developers expect the indirect network effect to apply, and the prospect of future growth matters to them when deciding with which platform to affiliate.     

中小科技企业低碳生产战略抉择的政企博弈模型分析

由于中小科技企业低碳生产受制于企业自主战略和外部环境两种因素,因此,科技企业履行低碳生产的社会责任行为,不仅包括在非市场环境中科技企业出于商业利益和社会营销考虑而自主实行的低碳行为,也包括受到利益相关者压力而被动采用的低碳行为。随着外部政策环境的明朗,科技企业低碳生产管理更加具有企业自发性。本文运用博弈论模型,将科技企业低碳生产管理与博弈论紧密结合起来分析,得出政企博弈纯策略和混合策略两种模型,从科技企业管理层面,为科技企业融入企业社会责任、规范合法经营提供了可行的管理指导。     

The leverage effect and the basket-index put spread

Benchmark models that exogenously specify equity dynamics cannot explain the large spread in prices between put options written on individual banks and options written on the bank index during the financial crisis. However, theory requires that asset dynamics be specified exogenously and that endogenously determined equity dynamics exhibit a “leverage effect” that increases put prices by fattening the left tail of the distribution. The leverage effect is larger for puts on individual stocks than for puts on the index, thus increasing the basket-index spread. Time-series and cross-sectional variation in the leverage effect explains option prices well.     

抵押物处置与农房抵押贷款困境：基于演化博弈的分析

研究目的:分析农民住房财产权抵押(简称农房抵押)贷款困境的主要原因以及抵押物处置对农房抵押贷款行为的影响机理。研究方法:演化博弈论。研究结果:农房抵押贷款发展面临困境的关键在于金融机构惜贷,而抵押物处置难是激发金融机构惜贷的重要原因,但是降低抵押物处置难度只是推动农房抵押贷款发展的必要而非充分条件。研究结论:要促进农房抵押贷款发展,除了必须降低抵押物处置难度外,还需要构建完善的农房抵押贷款制度体系。
