    in this paper, we present an integral equation approach for the valuation of american-style installment derivatives when the payment plan is assumed to be a continuous function of the asset price and time. the contribution of this study is threefold. first, we show that in the black–scholes model the option pricing problem can be formulated as a free boundary problem under very general conditions on payoff structure and payment schedule. second, by applying a fourier transform-based solution technique, we derive a system of coupled recursive integral equations for the pair of free boundaries along with an analytic representation of the option price. third, based on these results, we propose a unified framework which generalizes the existing methods and is capable of dealing with a wide range of monotonic payoff functions and continuous payment plans. finally, by using the illustrative example of american vanilla installment call options, an explicit pricing formula is obtained for time-varying payment schedules.
