概括
中国的实验游戏挑战了匹配便士的矛盾. 与美国研究不同的是,中国玩家没有表现出自己的回报偏见,这表明文化差异影响了游戏理论行为和平衡预测.
科学领域:
- 行为经济学是一种行为经济学.
- 游戏理论 游戏理论
- 实验经济学的实验经济学
背景情况:
- 非对称匹配便士游戏是混合策略纳什平衡预测的关键测试.
- 以前的研究,主要是在美国,显示玩家的选择受到他们自己的回报的影响,这与平衡理论相矛盾.
- 这种"自我回报效应"是实验经济学文献中一个强有力的发现.
研究的目的:
- 调查文化差异是否会影响玩家在不对称匹配便士游戏中的玩法.
- 测试中国受试者是否表现出西方受试者所观察到的"自我回报效应".
- 在集体主义文化背景下,探索从混合策略纳什平衡的行为偏差.
主要方法:
- 与中国参与者进行了一系列不对称的匹配便士游戏.
- 紧密复制了先前在美国进行的研究中使用的实验设置.
- 在量子响应平衡 (QRE) 框架内分析受试者选择.
主要成果:
- 与美国的研究结果相反,中国队的球员表现出很少或没有自己的回报效应,即使有很大的回报不对称.
- 中国样本中的行为与QRE模型中的正反抗参数保持一致.
- 以前的美国研究结果与QRE模型中的利他主义参数保持一致.
结论:
- 文化因素,特别是集体主义,可能会增强考虑他人的观点的能力,促进平衡游戏.
- 这些发现挑战了游戏理论实验中自身回报效应的普遍性.
- 结果表明,需要将文化层面纳入战略决策的经济模型.

Social psychologists have documented that feeling good about ourselves and maintaining positive self-esteem is a powerful motivator of human behavior (Tavris & Aronson, 2008). In the United States, members of the predominant culture typically think very highly of themselves and view themselves as good people who are above average on many desirable traits (Ehrlinger, Gilovich, & Ross, 2005). Often, our behavior, attitudes, and beliefs are affected when we experience a threat to our...

Bias refers to any tendency that prevents a question from being considered unprejudiced. In research, bias occurs when one outcome or answer is selected or encouraged over others in sampling or testing. Bias can occur during any research phase, including study design, data collection, analysis, and publication.
In statistics, a sampling bias is created when a sample is collected from a population, and some members of the population are not as likely to be chosen as others (remember, each member...

01:17Sign Test for Matched Pairs
155
The sign test for matched pairs offers a robust method for comparing two paired samples, often for the effects of an intervention in one of them. This method is very useful in situations where the underlying distribution of the data is unknown. The test compares two related samples—often pre- and post-treatment measurements on the same subjects—to determine if there are significant differences in their median values.
To conduct the sign test, we first calculate the differences in...

01:07Symmetric Member in Bending
190
In the study of the mechanics of materials, analyzing the behavior of prismatic members under opposing couples is crucial for understanding internal stress distributions, which are essential for structural design. When subjected to couples, a prismatic member experiences internal forces that maintain equilibrium. A couple, characterized by two equal and opposite forces, creates a moment but no resultant force. The internal forces at any section cut of the member must balance these external...

01:09Wilcoxon Signed-Ranks Test for Matched Pairs
156
The Wilcoxon signed-rank test for matched pairs evaluates the null hypothesis by combining the ranks of differences with their signs. It essentially tests whether the median of the differences in a population of matched pairs is zero. Since the test incorporates more information than the sign test, it generally yields more trustable conclusions. This test also does not require the data to follow a normal distribution, but two conditions must be met for it to be applicable: (1) the data must...

Social proof is a form of persuasion based on comparison and conformity. People compare their behavior and actions to what others are doing and will change to conform to do what their peers do.
