where N (d ) is the cumulative distribution for the normal random variable with the following de nitions d = 1 1 + L(t0 , Tn ) ln q 1+ K. t Tn + q2 2. (10.2). q 2 = q 2 (t0 , t , Tn ) = dt t0 Tn dxdx (t, x)D ( x, x ; t) (t, x ). (10.3). The domain of in tegration for evaluating q 2 is given in Figure 4.6. Note that q is the effective volatility for the caplet linear pricing formula and that the propagator for forward interest rates is required for pricing the caplet.

The pricing formulas for caplets and oorlets are xed by the volatility function (t, x), the correlation parameters , , contained in the Lagrangian for the forward interest rates, as well as the initial interest rates term structure. The Libor Market Model is based on nonlinear Libor forward interest rates and yields, as in Eq. (8.

4) are very different, re ecting the differences in the bond and Libor forward interest rates. The predictions of the linear only caplet price will be tested by comparing it with the market prices, leaving a similar study of Black s formula for the future. Black s formula, as it is currently used in the nancial markets, has no predictive power but instead is simply a convenient way of representing the price of a caplet.

The main utility of Black s formula is that implied B is more stable than the price itself and, similar to yield-to-maturity for coupon bonds, can be used for comparing caplets with different maturities, payoffs, and principal amounts.. 10.2 Linear and Black caplet prices The linear caple t price and Black s caplet formula are studied empirically using Libor market data. In particular, the effective volatility q determining the linear caplet price is computed by a three-dimensional integration on the covariance of the changes in the bond forward interest rates. The following three different approaches are discussed for xing the effective volatility q for pricing caplets.

. The volatility function H and parameters of the bond propagator, , , and , are all tted from historical Libor data. The market cov qr-codes for .NET ariance is computed directly from Libor market data. A parametric formula for the effective volatility q, and consequently for the implied.

volatility I fo r the linear caplet pricing model, is determined from historical caplet prices.3 The value of I is quite distinct from B since I is a function of future time and can be used for extrapolating the future. In contrast, B is a value that has to be computed every day from caplet prices.

. 10.2 Linear and .net framework QR Code Black caplet prices The pricing formula, at the money for a caplet maturing at t = Tn , is given by 1 + K = 1 + L(t0 , Tn ); K = L(t0 , Tn ).

The linear price of the caplet, at the money, is given by capletL (t0 , Tn ) = V [1 + L(t0 , Tn )]B(t0 , Tn+1 ) N (d+ ) N (d ) Note d = q 2 (10.5). This formula is qr codes for .NET compared with Black s formula. From Eq.

(10.4), Black s caplet formula at the money has K = L(t0 , Tn ) and yields the price caplet B (t0 , t , Tn ) = V L(t0 , Tn )B(t0 , Tn+1 ) N (d+ ) N (d ) q B t t0 = d = 2 2 At the money, since the pre-factors of two pricing formulas are different, the effective volatility q in the linear pricing formula and B in Black s formula are not equal. Black s formula is multiplied by (1 + L(t0 , Tn ))/ L(t0 , Tn ) so that at.
