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 investigates the institutional investors who hold nonzero synchronous positions in both derivative and underlying stocks to increase contract payoffs. We show that the potential manipulators settle or offset their TAIEX futures and options and simultaneously trade the constituent...

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)...

This paper provides further evidence regarding the effect of deposit insurance on the risk-shifting behavior at commercial banks in the United States. In particular, we compare the risk-shifting behavior of commercial banks before and after adopting the risk-based capital requirements in the...

This paper complements the extant literature to evaluate the prices of dynamic guaranteed funds when the price of underlying naked fund follows a double exponential jump-diffusion process. We first derive the closed-form solution for the Laplace transform of dynamic guaranteed fund price, and...

In this paper we provide an accurate and efficient method for valuing Asian options that works well for the low and medium volatility as well as longer average time window. Numerical results show that our method significantly outperforms the other analytic approximation methods in the...

While numerous prior studies report that call–put implied volatility spreads positively predict future stock returns, recent literature shows that the predictive relation is negative for future call option returns. We investigate whether and, if so, how the predictive relation for options...

This study follows the approach of Ni, Pan and Poteshman (2008) ndash; based upon the vega-weighted net demand for volatility ndash; to determine whether volatility information exists within the Taiwan options market. Our empirical results show that foreign institutional investors possess the...

This paper derives an integrated reduced-form model to calculate the values of adjustable-rate leases with embedded cancellation, purchase, and default options. We also provide numerical examples showing that for a 30-year lease contract, the lessor offers a 15% discount in the initial rent, but...
