摘要

巴黎期权是障碍期权的替代品，经常被嵌入复杂的金融衍生品中。尽管在定价方面存在相当大的数学挑战，但其在金融和保险领域的重要应用已引起了文献的广泛研究。然而，迄今为止，交易对手风险的影响尚未被考虑在内。为了弥补这一不足，我们为脆弱的巴黎期权开发了一个封闭式定价框架。利用拉普拉斯变换和度量变化技术，我们推导出了包含交易对手信用风险的巴黎期权闭式定价公式。最后，我们进行了数值分析，以验证我们的定价公式的准确性和效率。

On the pricing of vulnerable Parisian options

Parisian options, serving as substitutes for barrier options, are frequently embedded in complex financial derivatives. Despite the considerable mathematical challenges in pricing, their significant applications in finance and insurance have generated extensive studies in the literature. However, the impact of counterparty risk has not been taken into account so far. To address this gap, we develop a closed-form pricing framework for vulnerable Parisian options. Utilizing the Laplace transform and measure-change technique, we derive closed-form pricing formulas of Parisian options incorporating counterparty credit risk. Finally, we conduct numerical analyses to verify our pricing formulas’ accuracy and efficiency.
