【本期主题】Private Inside Information and Two-Stage Market Making: A Simple Model

In traditional market microstructure models, informed traders have inside information on the value of the assets and market makers understand the quality of the inside information (i.e. the distribution of the value of assets). While it is convenient to assume the prior of inside information is common knowledge, it may well be that market maker`s understanding of the quality of inside information is not perfect, or even very poor. In this paper, we study a model in which the informed trader receives a signal that is correlated with the true asset value. The correlation is known to the informed trader, but not to the market makers. The market makers know the distribution of the correlation. Drawing on the two-stage lottery literature, we solve the market making process in two steps and find that the extra layer of uncertainty will cause the informed trader trades less aggressively, the market makers become more conservative so that the price impact of any order will be larger, and the informed trader makes more profit.
