Abstract
This paper studies the pricing and hedging for American contingent claims in an incomplete market under mild conditions using the numeraire method to avoid changes of probability measure. When the market is incomplete, prices can not be derived by no-arbitrage arguments, since it is not possible to replicate the payoff of a given contingent claim by a controlled portfolio of the basic securities. We adopt the method of fictitious completion of [1] to provide an upper bound and a lower bound for the actual market price of the claim.
