| Abstract: | In this paper, the problem of hedging contingent claims by portfolios constrained to take values in a given convex, closed subset of R m in an incomplete market is studied. By extending the pair of portfolio and consumption to a triple of portfolio, extra investment and consumption, an interval of arbitrage free prices of a given contingent claim is gotten. |
