Glosten-Milgrom模型描述了一个单一的资产市场,在噪声交易者存在的情况下,知情交易者与做市商互动。通过{em i)}将该金融模型与SZIL'ARD信息引擎进行类比,表明后者的最优工作提取协议与前者的做市商定价策略一致;{em ii)}通过对市场订单分布的分析,定义了物理温度的市场类比。然后,我们证明了知情交易者的期望收益与市场温度与知情交易者所拥有的信息量的乘积有界,这与从信息引擎的一个循环中可以提取的最大期望工作量的相应公式完全相似。这表明,信息热力学的最新思想可以根据扩展的热力学第二定律的精神,揭示金融市场,并导致普遍的不等式。

英文摘要:
The Glosten-Milgrom model describes a single asset market, where informed traders interact with a market maker, in the presence of noise traders. We derive an analogy between this financial model and a Szil\'ard information engine by {\em i)} showing that the optimal work extraction protocol in the latter coincides with the pricing strategy of the market maker in the former and {\em ii)} defining a market analogue of the physical temperature from the analysis of the distribution of market orders. Then we show that the expected gain of informed traders is bounded above by the product of this market temperature with the amount of information that informed traders have, in exact analogy with the corresponding formula for the maximal expected amount of work that can be extracted from a cycle of the information engine. This suggests that recent ideas from information thermodynamics may shed light on financial markets, and lead to generalised inequalities, in the spirit of the extended second law of thermodynamics.
