Abstract
Under the conditions of the stock with or without dividends within the effective period,the problem of exchange option pricing with time-dependent parameters are discussed by using the approach of insurance actuarial pricing and the martingale method respectively.The Black-Scholes option pricing formulas with constant parameters are given as a special example.The relation between the two pricing methods is analyzed.It is thought that insurance actuarial pricing leads to arbitrage under general conditions.
