Tail integral of a levy process
http://www.columbia.edu/~sk75/levy.pdf WebBut like the BSM formula, BM is pop- ular due to its simplicity and analytical tractability (partly through Ito’s Lemma). Similar to BM, Levy process is a continuous time model but with jumps, with jump of difierent intensity and jump sizes superimposed to ensure analytical tracktability.
