Density of the set of probability measures with the martingale representation property

Let ψ be a multidimensional random variable. We show that the set of probability measures Q such that the Q-martingale SQt=EQ[ψ|Ft] has the Martingale Representation Property (MRP) is either empty or dense in L∞-norm. The proof is based on a related result involving analytic fields of terminal condi...
