Two Alternative Approaches to Derive Black
... In this chapter, we review two famous models on binomial option pricing, Rendleman and Barter (RB, 1979) and Cox, Ross, and Rubinstein (CRR, 1979). We show that the limiting results of the two models both lead to the celebrated Black-Scholes formula. From our detailed derivations, CRR is easy to fol ...

Lecture 7: Quadratic Variation
... By letting t → T in equation (70), we see that any European-style twicedifferentiable payoff may be replicated using a portfolio of European options with strikes from 0 to ∞ with the weight of each option equal to the second derivative of the payoff at the strike price of the option. This portfolio ...

Elementary Asset Pricing Theory 1 The simplest model
... The cash flow convention is that positive numbers represent cash received by the owner of the asset and negative quantities represent cash payed out by the owner. Thus the 0th component of Ai is negative if pi0 is positive, because to purchase a unit of asset i requires a cash payment if the price i ...

Let us assume an interest r, a time n (years), and an amount A ($$). In n years the amount A has n the value A( 1 r ) . ...
