摘要翻译：
本文研究了随机利率下基于一般强度的信用风险模型中信用衍生品的最优清算时机。我们考虑了市场和投资者之间的潜在价格差异，这种差异的特征是在不同的违约风险premia规范下的风险中性估值。通过延迟平仓溢价的概念来量化最优卖出时机的价值，并分析了相关的概率表示和变分不等式。我们给出了单名和多名信用衍生品的最优清算策略。我们的模型被推广到研究有卖空约束和无卖空约束的顺序买卖问题。

英文摘要：
This paper studies the optimal timing to liquidate credit derivatives in a general intensity-based credit risk model under stochastic interest rate. We incorporate the potential price discrepancy between the market and investors, which is characterized by risk-neutral valuation under different default risk premia specifications. We quantify the value of optimally timing to sell through the concept of delayed liquidation premium, and analyze the associated probabilistic representation and variational inequality. We illustrate the optimal liquidation policy for both single-named and multi-named credit derivatives. Our model is extended to study the sequential buying and selling problem with and without short-sale constraint.
