Monotone Martingale Transport Plans and Skorohod Embedding
نویسندگان
چکیده
We show that the left-monotone martingale coupling is optimal for any given performance function satisfying the martingale version of the Spence-Mirrlees condition, without assuming additional structural conditions on the marginals. We also give a new interpretation of the left monotone coupling in terms of Skorokhod embedding which allows us to give a short proof of uniqueness.

An explicit martingale version of the one-dimensional Brenier theorem
By investigating model-independent bounds for exotic options in financial mathematics, a martingale version of the Monge-Kantorovich mass transport problem was introduced in [3, 24]. Further, by suitable adaptation of the notion of cyclical monotonicity, [4] obtained an extension of the one-dimensional Brenier’s theorem to the present martingale version. In this paper, we complement the previou...
متن کاملMartingale optimal transport and robust hedging
The martingale optimal transport problem is motivated by model-independent bounds for the pricing and hedging exotic options. In the simplest one-period model, the dual formulation of the robust superhedg-ing cost differs from the standard optimal transport problem by the presence of a martingale constraint on the set of coupling measures. The one-dimensional Brenier theorem has a natural exten...

متن کاملMonotonicity of transport plans
We study monotonicity properties for minimizers of transport problems. In the one-dimensional case, we present an algorithm to construct minimizing monotone transport plans by “monotonizing” a given minimizing transport plan. This method applies in particular to the case of the L1-Wasserstein metric where we prove the existence of monotone minimizers for arbitrary marginals. We find that monoto...
متن کاملRepresentation results for law invariant time consistent functions
We show that the only dynamic risk measure which is law invariant, time consistent and relevant is the entropic one. Moreover, a real valued function c on L∞(a, b) is normalized, strictly monotone, continuous, law invariant, time consistent and has the Fatou property if and only if it is of the form c(X) = u−1 ◦ E [u(X)], where u : (a, b) → R is a strictly increasing, continuous function. The p...
