利用单期静态博弈分析法、有限期动态博弈分析法和无限期动态博弈分析法对成品油定价机制中寡头厂商的合谋行为进行了分析。研究发现:两家寡头厂商在合谋条件下的收益均高于双方各自独立定产条件下的收益,因此,双方存在进行价格合谋的利益激励。基于此,我国成品油价格形成机制的改革可以考虑采用有限规制等手段。 相似文献

Using data from a large representative US sample (N = 1519), we compare hypothetical moral fairness values from the Moral Foundations Sacredness Scale with actual fairness behavior in an incentivized dictator game with either low or high stakes. We find that people with high moral fairness values fail to live up to their high fairness standards, when stake size increases. This violates principles from consistency theories according to which moral values are supposedly aligned with moral behavior, but is in line with temptation theories that question the absoluteness of morality values. 相似文献

儿童文学的"游戏精神"主要是指在儿童作品文本中体现出的、通过人物游戏所传递的一种符合儿童心理需求和审美旨趣,并实现儿童内心愿望的精神。周作人认为儿童文学的游戏精神是"幻想精神""愉悦精神"和"自由精神"。儿童文学游戏精神具有快乐性、幻想性和自由性的三性特征"。游戏精神"在儿童文学中作品的主要呈现形式为:通过"顽童""小大人""、反派"等人物形象的塑造凸显游戏精神;通过故事情节蕴涵的笨拙与聪明、嬉笑与吵闹、虚拟与真实凸显游戏精神;通过语言夸张凸显荒诞美、语言颠倒凸显逆向思维、语言突转凸显惊奇,从而凸显游戏精神。游戏精神对于儿童文学作品编创的意义在于:游戏精神是儿童文学的基本属性和内涵所在,新媒介时代儿童文学的发展需要延续游戏精神。因此游戏精神是儿童文学的作品编创的重要依据和准则。 相似文献

We demonstrate that personality has a systematic effect on strategic behavior. We focus on two personality traits: anxiousness and aggressiveness, and consider a 2-player entry game, where each player can guarantee a payoff by staying out, a higher payoff if she is the only player to enter, but a lower payoff if both players enter. We find that: anxious players enter less; aggressive players enter more; players are more likely to enter against anxious than non-anxious players; and players are less likely to enter against aggressive than non-aggressive players. We discuss the possible mechanism through which personality affects strategic behavior. 相似文献

现有研究所提出的消解公共政策执行阻滞现象的对策多为事后性对策,且偏于刚性方式。以博弈论为理论依据,通过建构传统策略下中央与地方的策略互动、“协调”作为中央策略下的策略互动、协调引入博弈最始端下的策略互动三个博弈模型,比较得出将协调引入公共政策的制定和执行中,将有助于公共政策执行阻滞现象的减少和消除,并在此基础上提出以协调为理念构建的对策。 相似文献

We analyze a signaling game between the manager of a firm and an investor in the firm. The manager has private information about the firm's demand and cares about the short‐term stock price assigned by the investor. Previous research has shown that under continuous decision choices and the Intuitive Criterion refinement, the least‐cost separating equilibrium will result, in which a low‐quality firm chooses its optimal capacity and a high‐quality firm over‐invests in order to signal its quality to investors. We build on this research by showing the existence of pooling outcomes in which low‐quality firms over‐invest and high‐quality firms under‐invest so as to provide identical signals to investors. The pooling equilibrium is practically appealing because it yields a Pareto improvement compared to the least‐cost separating equilibrium. Distinguishing features of our analysis are that: (i) we allow the capacity decision to have either discrete or continuous support, and (ii) we allow beliefs to be refined based on either the Undefeated refinement or the Intuitive Criterion refinement. We find that the newsvendor model parameters impact the likelihood of a pooling outcome, and this impact changes in both sign and magnitude depending on which refinement is used. 相似文献

We study competition and coordination in a supply chain in which a single supplier both operates a direct channel and sells its product through multiple differentiated retailers. We study analytically the supply chain with symmetric retailers and find that the supplier prefers to have as many retailers as possible in the market, even if the retailers' equilibrium retail price is lower than that of the supplier, and even if the number of retailers and their cost or market advantage prevent sales through the direct channel. We find that the two‐channel supply chain may be subject to inefficiencies not present in the single‐channel supply chain. We show that several contracts known to coordinate a single‐channel supply chain do not coordinate the two‐channel supply chain; thus we propose a linear quantity discount contract and demonstrate its ability to perfectly coordinate the two‐channel supply chain with symmetric retailers. We provide some analytical results for the supply chain with asymmetric retailers and propose an efficient solution approach for finding the equilibrium. We find numerically that the supplier still benefits from having more retailers in the market and that linear quantity discount contracts can mitigate supply chain inefficiency, though they no longer achieve perfect coordination. 相似文献

目前为止,共享单车用户的机会主义行为是共享单车能否发展的关键制约因素之一。基于此,尝试用演化博弈理论建立共享单车企业与用户间的演化博弈模型发掘用户的机会主义行为动因及利益相关者作用。研究表明:用户收益是其行为选择的决定性因素,用户机会主义行为收益大于规范行为收益是机会主义行为的产生根源;共享单车企业的激励约束可对用户行为起到调节作用,约束强度将对用户机会主义行为的程度产生负向影响。最后,针对演化博弈模型分析结果,提出了相应管理对策建议。 相似文献
