钱包赌戏悖论及其行为的经济学意义

On the Irrational Effect of the Purse-game Paradox and Its Implication to Behavioral Economics

本文对行为经济学的一个重要微观模型———钱包赌戏悖论建立了认知分析框架 ,不仅彻底消解了该悖论 ,还发现了与效用和概率均无关的一种新的非理性效应。这一效应既可能导致无帕累托效率的交易陷阱 ,也可能与效用歧化和概率误判等已知的行为经济学效应协同作用 ,产生更复杂的非理性决策。

A cognitive framework of the purse-game paradox which is an important micro model in the behavioral economics is established; this framework not only clears up the paradox completely, but also shows a new irrational effect which is irrelevant to the utility and probability. This effect could bring on the transaction trap and produce more complicated irrational decision making together with some known effects of behavioral economics.
