In particular, we work under essentially minimal regularity conditions and treat the time-inhomogeneous case. Copyright...</para>

Let Q and P be equivalent probability measures and let ψ be a J-dimensional vector of random variables such that dQdP and ψ are defined in terms of a weak solution X to a d-dimensional stochastic differential equation. Motivated by the problem of endogenous completeness in financial economics...
