摘要: | KYLE[1985]中探討了線性的內線交易模型,並且得到一組唯一的線性均衡解。在本篇論文中,我們考慮相似的交易模型,並做兩部分的調整。第一部分,我們討論當市場訂價機制不再是線型函數而為指數函數時,是否存在均衡解。第二部分,我們依然使用KYLE的線性模型,但不同點在於我們不使用布朗運動,而改用分數布朗運動作為一般交易者的交易總量變化過程,然後在此模型下探討是否存在連續競價均衡解。 KYLE [1985] proposed a model of insider trading in discrete-time and continuous time, and obtained a unique equilibrium. In this thesis, we consider two generalized discrete-time models. The first part, we discuss whether there exists an equilibrium when the pricing rule is no more a linear function but an exponential function. The second part, instead of classical Brownian motion, in Kyle’s linear model we investigate a model with a fractional Brownian motion as noise traders’ trading volume, and discuss if there exists a sequential equilibrium under this model. |
