PRICING OF NEW SECURITIES IN AN INCOMPLETE MARKET: THE CATCH 22 OF NO-ARBITRAGE PRICING

摘要

There are two distinctly different approaches to the valuation of a new security in an incomplete market. The first approach takes the prices of the existing securities as fixed and uses no-arbitrage arguments to derive the set of equivalent martingale measures that are consistent with the initial prices of the traded securities. The price of the new security is then obtained by appealing to certain criteria or on the basis of some preference assumption.
