Marc Henrard, SSRN, The Irony in the Derivatives Discounting, 2007, here.
Abstract:A simple and fundamental question in derivatives pricing is the way (contingent) cash-flows should be discounted. As cash can not be invested at Libor the curve is probably not the right discounting curve, even for Libor derivatives. The impact on derivative pricing of changing the discounting curve is discussed. The pricing formulas for vanilla products are revisited in the funding framework described.
The Irony in the Derivatives Discounting Part II: The Crisis, 2009, here.
Abstract:Libor derivative pricing has changed with the crisis; Libor is not anymore one unambiguous curve as a large basis has appeared between different Libor tenors. A previous approach to derivative discounting is reviewed at the light of those changes. The valuation of so called linear derivatives, the yield curve construction and the valuation of vanilla options is analyzed.
