In a Black and Scholes (1973) world I study the pricing performance of a closed-form lower bound to American option values based on an exercise strategy corresponding to a flat exercise boundary. The lower bound has a simple two-step implementation akin to the Barone-Adesi and Whaley (1987) formula and shows superior pricing performance in the Out-of-The-Money region and for long maturities.

Abstract
In a Black and Scholes (1973) world I study the pricing performance of a closed-form lower bound to American option values based on an exercise strategy corresponding to a flat exercise boundary. The lower bound has a simple two-step implementation akin to the Barone-Adesi and Whaley (1987) formula and shows superior pricing performance in the Out-of-The-Money region and for long maturities.
