LECTURE 12: STOCHASTIC DIFFERENTIAL EQUATIONS, DIFFUSION. processes , AND THE FEYNMAN-KAC FORMULA. 1. Existence and Uniqueness of Solutions to SDEs It is frequently the case that economic or financial considerations will suggest that a stock price, exchange rate, interest rate, or other economic variable evolves in time according to a STOCHASTIC DIFFERENTIAL equation of the form (1) dXt = (t, Xt ) dt + (t, Xt ) dWt where Wt is a standard Brownian motion and and are given functions of time t and the current state x. More generally, when several related economic variables X 1 , X 2.
