Structure of optimal martingale transport plans in general dimensions
- Abstract:
-
Given two probability measures μ and ν in “convex order” on Rd, we study the profile of one-step martingale plans π on Rd×Rd that optimize the expected value of the modulus of their increment among all martingales having μ and ν as marginals. While there is a great deal of results for the real line (i.e., when d=1), much less is known in the richer and more delicate higher-dimensional case that we tackle in this paper. We show that many structural results can be obtained, provided the initial...
