To find the explicit closed-form formulas for the zero-order term and the first-order correction term, we use Mellin transform. We also conduct a sensitivity analysis on these formulas, and compare the option prices calculated by them with those generated by Monte-Carlo simulation.https://creativecommons.org/licenses/by/4.0/3502 Banking, Finance and Investment35 Commerce, Management, Tourism and Services35 Commerce, management, tourism and services38 EconomicsJournal ArticleOpenAccess10.3390/jrfm16100456
