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

component can be thought of as a price for the

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

is the solvency cone for the market at time

[1][2] The CPP plays the role of an equivalent martingale measure in markets with transaction costs.

[3] In particular, there exists a 1-to-1 correspondence between the CPP
