Experimental Tests of Core Theory and the Coase Theorem: Inefficiency and Cycling
通过实验检验核心存在与否对谈判结果的影响,发现核心为空且产权不明晰时,科斯效率失效,无效率协议和循环谈判显著增加。
We examine experimentally the bargaining process and the final allocation of payoffs in games that differ in terms of whether the core exists and in the initial allocation of property rights among the players. This paper highlights the interaction among property rights, transaction costs, and the empty core. Our experimental results indicate that the existence of the core is an important determinant of bargaining generally and the Coase theorem in particular. They confirm our conjecture that when the core is empty and property rights are ill defined, Coasean efficiency breaks down. Among other results, our experiments show that the number of inefficient (non‐Pareto‐optimal) agreements and bargaining rounds with cycling are significantly greater when the core is empty than when the core exists, especially when property rights are ill defined. Our results suggest an economic role for specific property right arrangements to resolve the empty core.
