Consistent pricing process : ウィキペディア英語版 | Consistent pricing process
A consistent pricing process (CPP) is any representation of (frictionless) "prices" of assets in a market. It is a stochastic process in a filtered probability space such that at time the component can be thought of as a price for the asset. Mathematically, a CPP in a market with d-assets is an adapted process in if ''Z'' is a martingale with respect to the physical probability measure , and if at all times such that is the solvency cone for the market at time . The CPP plays the role of an equivalent martingale measure in markets with transaction costs. In particular, there exists a 1-to-1 correspondence between the CPP and the EMM . ==References==
