2、lio4.Market Price of Risk (Page 500)This shows that (m r )/s is the same for all derivatives dependent on the same underlying variable, qWe refer to (m r )/s as the market price of risk for q and denote it by l5.Differential Equation for (Equation 19.10, page 501)Using Itos lemma to obtain expressio

3、ns for m and s in terms of m and s. The equation m-ls=r becomes6.Risk-Neutral ValuationThe differential equation shows that q is like a stock price paying a dividend yield of r m + lsThis analogy shows that we can value in a risk-neutral world providing the drift rate of q is reduced from m to m ls7

4、.Extension of the Analysisto Several Underlying Variables(Equations 19.12 and 19.13, page 503)8.Derivatives Dependent on Commodity Prices (Page 506)For a commodity the futures price gives the expected value in the traditional risk-neutral world9.Martingales (Page 507)A martingale is a stochastic pro

Using the money market account as the numeraire leads to the traditional risk-neutral world15.Money Market Accountcontinued 16.Zero-Coupon Bond Maturing at time T as Numeraire 17.Forward PricesIn a world tha
