In this paper, we propose a new model for the (B,S)-market in which the sto
ck price and the asset in the riskless bank account have hereditary price s
tructures. Specifically, the dynamics of the stock price and the bank accou
nt are described by linear stochastic functional differential equations. Th
e pricing of the European contingent claims is studied and the correspondin
g trading strategy is derived. (C) 1999 Published by Elsevier Science Inc.
