This book proposes a closed-form solution for pricing an American put option on a non-dividend paying stock based on an optimally early-exercise strategy. An American put option should be early exercised when the maximum option premium of early exercise is not less than the value of its European counterpart; otherwise, it should not be early exercised. This paper also shows that Merton (1973)¿s formula for pricing a perpetual American put option on a non-dividend paying stock is not perfect and shows such an option¿s value is equal to its strike price.
