Information and Cost Asymmetry in Experimental Duopoly Markets
通过实验双寡头市场数据，分析信息（盈利性为共同知识还是私人信息）对合谋的影响，发现对称市场中共同知识促进合作，不对称市场中共同知识提高低效生产者的产出份额和行业效率。
We analyze data from experimental duopoly markets to assess the role information plays in facilitating collusion. In these markets, profitability can be common knowledge or private information. Market outputs are estimated in structures with symmetric and asymmetric costs under the two information conditions. Symmetric markets are more cooperative when profitability is common knowledge; asymmetric market outputs are unaffected by information differences. However, common knowledge in asymmetric markets increases the share of the output produced by the low-cost producer, and therefore increases industry efficiency.
