摘要

Consider a sequence of random vectors Y(1),..., Y(n) in R~d, with a known joint distribution, finite expectations, adapted to a filtration F. For a given monotone function h : R~d → R, a randomized stopping rule t such that sup_t h(EY(t)) = h(EY(t)) is desired. A full solution to this problem is given. In particular we show that there exists a vector of constants a = (a_1,..., a_d) such that the optimizing t is optimal also for the one-dimensional optimal stopping problem, where the sequence of rewards is Z(1),... ,Z(d) with Z(j) = ∑ from i=1 to d of a_iY_i(j). With symmetry assumptions the a vector will be (1,...,1). The results are extended also to the infinite horizon case and are applied to obtain an explicit solution to the multivariate "house-selling problem."
