In this paper we re-examine the American-style option pricing formula of Geske and Johnson (1984) and extend the analysis by deriving a modified formula that can overcome the possibility of non-uniform convergence encountered in the original Geske-Johnson methodology. Furthermore, we propose a...

Most papers studying loan guarantee are under a one-borrower and one-guarantor framework. This study uses the option approach to construct models in which loan guarantees are analyzed under a multiple-borrower and one-guarantor framework and under a one-borrower and multiple-guarantor structure...

This study extends the Hull and White (1993 J. Derivatives 1 21-31) binomial method to construct a trinomial model for the valuation of American-style options whose strike price can be reset to a new level. The reset criterion is conditioned upon the average underlying asset price hitting the...

This paper describes four separate option types as special cases of Bermudans with general inter - exercise and time to final maturity. This produces a surface with European, finite American, infinite Bermudan and infinite American options as special cases. This allows Geske-Johnson 1984)...
