指数Lévy模型中期权价格的连续性

On continuity properties for option prices in exponential Lévy models

S. Cawston, L. Vostrikova

摘要:

对于指数Lévy模型的收敛序列,给出了相应的期权价格序列收敛的条件。我们还研究了价格的行为时,没有这样的收敛。然后,我们考虑两种特殊情况下,首先当选择的鞅测度的熵最小化,然后当它最小化海林格积分。

英文摘要:

For a converging sequence of exponential Lévy models, we give conditions under which the associated sequence of option prices converges. We also study the behaviour of the prices when no such convergence holds. We then consider two special cases, first when the martingale measure is chosen by minimisation of entropy and then when it minimises Hellinger integrals.
