摘  要: This paper provides three generic improvements to least square Monte Carlo approaches for solving optimal stopping problems. First, we modify the regression specification to target the stopping boundary directly. Second, we employ Bayesian model averaging to select the set of basis functions used in the least square regression. Third, we formulate a single index regression to reduce the dimensionality without substantial compromise in results. Without loss of generality, we demonstrate the implementation of each improvement on a different early exercisable product and compare the results with established methods. We emphasise that the methods introduced are not only generic but are easily transplanted to any scenario where least square Monte Carlo is viable without any signi_cant increase in computational cost.
