Choosing on influence
研究个体在互动中如何寻求影响以解决自身无法解决的问题，通过选择理论方法识别互动个体，并揭示其潜在偏好与获得的影响。
Interaction, the act of mutual influence, is an essential part of daily life and economic decisions. This paper presents an individual decision procedure for interacting individuals. According to our model, individuals seek influence from each other for those issues that they cannot solve on their own. Following a choice-theoretic approach, we provide simple properties that aid us to detect interacting individuals. Revealed preference analysis not only grants underlying preferences, but also the influence acquired.
