在网络市场中，信息可以帮助企业更好地决定参与哪个市场（平台）以及参与多少。然而，这些市场可能在时间上是分开的，例如不同地理位置的独立系统运营商。我们通过网络古诺市场对这些进行建模，但相反，考虑一家公司的参与要么是随机市场的实现（或完整信息），要么仅是随机市场的统计数据，由最大价格上的附加零均值随机变量 z 建模。我们表明，不知道随机变量 z 实现情况的公司会以与实现均值相同的方式参与两个市场。然后我们提出全球效应：我们证明，当信息改善时，每个公司的利润都会提高，但信息越多，社会福利可能会变得更好或更差。
In networked markets, information can help firms make better decisions on which market (platform), and how much, to participate. However, these markets may be temporally separated, e.g. independent system operators in different geographical locations. We model these via networked Cournot markets, but instead consider the participation of one firm to either be with the realization (or full information) of a random market, or only with the statistics of the random market, modeled by an additive zero-mean random variable z on the maximal price. We show that firms not knowing the realization of the random variable z would participate in both markets in the same way as if the mean was realized. We then present global effects: we prove that profit is improved for every firm when one’s information improves but social welfare may get better or worst with more information.
