Optimal stopping in Levy models, for non-monotone discontinuous payoffsSvetlanaBoyarchenkoauthorSergeiLevendorskiiauthorWe give short proofs of general theorems about optimal entry and exit problems in Levy models, when payoff streams may have discontinuities and be non-monotone. As applications, we consider exit and entry problems in the theory of real options, and an entry problem with an embedded option to exit.D81 - Criteria for Decision-Making under Risk and UncertaintyC61 - Optimization Techniques ; Programming Models ; Dynamic Analysis2010-09MPRA Paper
