This paper puts forward a valuation framework for mortgage-backed securities. Rather than imposing an optimal, value minimizing call condition, the authors assume that at each point in time there exists a probability of prepaying, this conditional probability depending upon the prevailing state of the economy. To implement their valuation procedure, the authors use maximum likelihood techniques to estimate a prepayment function in light of recent aggregate GNMA prepayment experience. By integrating this empirical prepayment function into their valuation framework, they provide a complete model to value mortgage-backed securities. Copyright 1989 by American Finance Association.
