For x ∈ Z we write Tx = inf {n : Sn = x} , 40 trees and martingales and define x 1− p p φ(x) = Then for a < 0 < b, P [Ta < Tb ] = . 1 − φ(b) . φ(a) − φ(b) Proof: We first show that {φ(Sn )}n≥0 is a P-martingale. Since the walk can only take one step at a time, −n ≤ Sn ≤ n. Using also that 0 < (1 − p)/ p < 1 for p > 1/2, we evidently have that E [|φ(Sn )|] < ∞, ∀n. To check that we really have a martingale is reduced to another exercise in conditional expectations. We must calculate E φ(Sn+1 )| Fn .

As before we assume that unlimited amounts of both can be bought and sold without transaction costs. There is no risk of default on a promise and the market is prepared to buy and sell a security for the same price (that is, there is no bid–offer spread). 1 S3 The tree of stock prices. We suppose the market to be observable at times 0 = t0 < t1 < · · · < t N = T . The stock Over each time period [ti , ti+1 ] the stock follows the binary model. 1. After i time periods, the stock can have any of 2i possible values.

First let us calculate the conditional expectation E [ X 3 | F1 ] . Using our interpretation of Fn as ‘information up to time n’, our problem is to determine the conditional expectation of X 3 given all the information up to time one. Notice that what we are calculating is an F1 -measurable random variable. It depends only on what happened up until time one. There are just two possibilities: the first jump is up, or the first jump is down. • If the first jump is up, the possible values of X 3 are X 3000 , X 3001 , X 3010 and X 3011 .
