A Remark on American Securities

  • Shigeo Kusuoka


In this paper, we discuss about American securities. To simplify the notions, we only discuss the case that the free risk spot rate is zero and the maturity (or the horizon) is 1 (So the price of free risk bond is constant). Also we assume that there is no dividend or no transaction cost and that there is no restriction on short sale.
