This paper introduces an analytically tractable method for the pricing of European and American Parisian options in a flexible jump–diffusion model. Our contribution is threefold. First, using a double Laplace–Carson transform with respect to the option maturity and the Parisian (excursion) time, we obtain closed-form solutions for different types of Parisian contracts. Our approach allows us also to analytically disentangle contributions of the jump and diffusion components for Parisian options in the excursion region. Second, we provide numerical examples and quantify the impact of jumps on the option price and the Greeks. Finally, we study the non-monotonic effects of volatility and jump intensity close to the excursion barrier, which are important for shareholders’ investment policy decisions in a levered firm.

Notes
1 We note that Carr (Citation1998) relied on the Post–Widder inversion, whereas our implementation rests on the Gaver–Stehfest inversion. For further discussion and technical details regarding the two approaches, we refer an interested reader to Kimura (Citation2010) and Leippold and Vasiljević (Citation2017).
3 Some other types of occupation–time derivatives are analysed in the presence of jump risk (Ait Aoudia and Renaud Citation2016, Cai et al.Citation2010, Wu and Zhou Citation2016).
4 In the case of foreign exchange options, r and represent a domestic and a foreign risk-free interest rate, respectively.
5 Naturally, the probabilities of positive and negative jumps satisfy the condition .
6 For example, a European Parisian up-and-out option is a European-style derivative contract with a knock-out feature which is activated when the underlying process consecutively spends a prespecified amount of time above a certain threshold level.
7 We arbitrarily choose the barrier level to be above the strike price, i.e. .
8 The associated boundary conditions for EPOUP and APOUP options are given in equations (Equation21(21) ) and (Equation43(43) ), respectively.
9 Both modifications of the original pricing domain are thoroughly discussed in Zhu and Chen (Citation2013), pp. 876–879.
10 For example, see Detemple (Citation2005), pp. 55–59, and Jeanblanc et al. (Citation2009), pp. 191–198.
11 We conducted extensive numerical tests and concluded that sensitivities of EPUOP and APUOP options exhibit similar behaviour. Therefore, to facilitate the presentation of our numerical results, we focus on European-style Parisian options in figure . To allow for future comparisons, additional numerical results are provided in table .
12 We only consider EPUOP options, however similar conclusions can be derived for their American counterparts.
14 This result is intuitive. If the Parisian window shrinks, then it becomes more likely that an APUOP option might be knocked out. As a consequence, the early exercise boundary is pushed higher, i.e. an option holder has an incentive to exercise earlier due to the increased likelihood of the option being cancelled at some point in the future.
