Cramér asymptotics for finite time first passage probabilities of general Lévy processes
Résumé
We derive the exact asymptotics of if and tend to infinity with constant, for a general Lévy process that admits exponential moments. The proof is based on a renewal argument and a two-dimensional renewal theorem of Höglund [Höglund, T., 1990. An asymptotic expression for the probability of ruin within finite time. Ann. Prob., 18, 378–389].
