摘要：
Motivated by recent studies in financial mathematics and other areas, we investigate the exponential functional Z = integral(infinity)(o) e(-X(t))dt of a Levy process X(t), t >= 0. In particular, we investigate its tail asymptotics. We show that, depending on the right tail of X(1), the tail behavior of Z is exponential, Pareto, or extremely heavy-tailed. (C) 2005 Elsevier B.V.
