报告摘要:

The theory of valuation is changing considerably after the beginnings of Bachelier (1900) and Black Scholes (1973). The current practice of including valuation adjustments for previously neglected risks such as Credit, Collateral and Funding Costs is reviewed and criticized, based on our research in the period 2002-2014. In particular, one may consider the inclusion of funding and margining costs for the hedge and collateral processes in a portfolio of trades. In presence of asymmetric borrowing and lending rates such costs lead to valuation equations that are nonlinear in terms of pricing operators. Rather than risk neutral expected values of discounted cash flows one obtains nonlinear mathematical representations such as nonlinear PDEs or Backward SDEs. Another way to look at this is saying that the pricing measure depends on the specific deal being priced and on the conditions under which the deal is traded, leading to a sort of relativity of the pricing measure and to recursive equations. Portfolio valuation becomes aggregation-dependent and the operational implications of the basic financial fact that borrowing and lending happen at different rates are highlighted.
