标题： Stock loans with liquidation

摘要： 我们推导了一个由超指数模型（HEM）驱动的股票贷款的半解析解，在这种情况下，当股票价格降至足够低时，贷款人可以进行清算。 为此，我们将N. Cai等人关于HEM首次通过时间的广义拉普拉斯变换的结果扩展到两个平直屏障，这本身具有独立的兴趣。 显示英文摘要

摘要： We derive a semi-analytic solution for a stock loan driven by a hyper-exponential model (HEM) in which the lender is allowed to liquidate when the stock drops to a sufficiently low price. To do so, we extend a result of N. Cai et al. regarding the generalized Laplace transform of the first passage time of the HEM to two flat barriers, which is of independent interest.
