8 MAS352/452/6052 Formula Sheet Part One Where not explicitly specified, the notation used matches that within the typed lecture notes. Modes of convergence X n d X for any x R, limn P[X n x] P[X x]. X n P X for any a > 0, limn P[ X n X > a] = 0. X n a.s. X P[X n X as n ] = 1. X n L p X E[ X n X p ] 0 as n. The binomial model and the one-period model The binomial model is parametrized by the deterministic constants r (discrete interest rate), p u and p d (probabilities of stock price increase/decrease), u and d (factors of stock price increase/decrease), and s (initial stock price). The value of x in cash, held at time t, will become x(1+r) at time t+1. The value of a unit of stock S t, at time t, satisfies S t+1 = Z n S n, where P[Z t = u] = p u and P[Z t = d] = p d, with initial value S 0 = s. When d < 1+r < u, the risk-neutral probabilities are given by q u = (1+r) d u d, q d = u (1+r). u d The binomial model has discrete time t = 0,1,2,...,T. The case T = 1 is known as the one-period model. Conditions for the optional stopping theorem (MAS452/6052 only) The optional stopping theorem, for a martingale M n and a stopping time T, holds if any one of the following conditions is fulfilled: (a) T is bounded. (b) M n is bounded and P[T < ] = 1. (c) E[T] < and there exists c R such that M n M n 1 c for all n.
9 MAS352/452/6052 Formula Sheet Part Two Where not explicitly specified, the notation used matches that within the typed lecture notes. The normal distribution Z N(µ,σ 2 ) has probability density function f Z (z) = 1 2πσ e (z µ)2 2σ 2. Moments: E[Z] = µ, E[Z 2 ] = σ 2 +µ 2, E[e Z ] = e µ+1 2 σ2. Ito s formula For an Ito process X t with stochastic differential dx t = F t dt + G t db t, and a suitably differentiable function f(t,x), it holds that { f dz t = t (t,x f t)+f t x (t,x t)+ 1 2 } f f 2 G2 t x 2(t,X t) dt+g t x (t,x t)db t where Z t = f(t,x t ). Geometric Brownian motion For deterministic constants α,σ R, and u [t,t] the solution to the stochastic differential equation dx u = αx u dt+σx u db u satisfies X T = X t e (α 1 2 σ2 )(T t)+σ(b T B t). The Feyman-Kac formula Suppose that F(t,x), for t [0,T] and x R, satisfies F t (t,x)+α(t,x) F x (t,x)+ 1 2 β(t,x)2 2 F x 2 (t,x) = 0 F(T,x) = Φ(x). Then F(t,x) = E t,x [Φ(X T )], where X u satisfies dx u = α(u,x u )dt+β(u,x u )db u.
10 The Black-Scholes model The Black-Scholes model is parametrized by the deterministic constants r (continuous interest rate), µ (stock price drift) and σ (stock price volatility). The value of a unit of cash C t satisfies dc t = rc t dt, with initial value C 0 = 1. The value of a unit of stock S t satisfies ds t = µs t dt+σs t db t, with initial value S 0. At timet [0,T], the price F(t,S t ) ofacontingent claim Φ(S T ) (satisfyinge Q [Φ(S T )] < ) withexercise date T > 0 satisfies the Black-Scholes PDE: The unique solution F satisfies F t (t,s)+rs F s (t,s)+ 1 2 s2 σ 2 2 F (t,s) rf(t,s) = 0, s2 F(T,s) = Φ(s). F(t,S t ) = e r(t t) E Q [Φ(S T ) F t ] for all t [0,T]. Here, the risk-neutral world Q is the probability measure under which S t satisfies ds t = rs t dt+σs t db t. The Gai-Kapadia model of debt contagion (MAS452/6052 only) A financial network consists of banks and loans, represented respectively as the vertices V and (directed) edges E of a graph G. An edge from vertex X to vertex Y represents a loan owed by bank X to bank Y. Each loan has two possible states: healthy, or defaulted. Each bank has two possible states: healthy, or failed. Initially, all banks are assumed to be healthy, and all loans between all banks are assumed to be healthy. Given a sequence of contagion probabilities η j [0,1], we define a model of debt contagion by assuming that: ( ) For any bank X, with in-degree j if, at any point, X is healthy and one of the loans owed to X becomes defaulted, then with probability η j the bank X fails, independently of all else. All loans owed by bank X then become defaulted. Starting from some set of newly defaulted loans, the assumption ( ) is applied iteratively until no more loans default.
