Der Idee von Geske und Johnson folgend wird der Preis einer amerikanischen Put-Option durch den Preis einer n-Bermuda-Put-Option approximiert. Die Problematik der Berechnung von der in der analytischen Bewertungsformeln von Geske und Johnson auftretenden multidimensionalen...

This study proposes a numerical integration technique to determine the approximate integral of the neutrosophic valued function. Newton Cot's method with a positive coefficient has been used for neutrosophic integration, and then the suggested technique is used to find the approximate value of...

We analyze American put options in a hyper-exponential jump-diffusion model. Our contribution is threefold. Firstly, by following a maturity randomization approach, we solve the partial integro-differential equation and obtain a tight lower bound for the American option price. Secondly, our...
