| Description | |||||||||||||||||||||||||||||||||||||||||||||
|
This module provides a thorough introduction to Brownian motion , stochastic calculus and their application to finance. It builds on Probability and Finance I in that it deals with the problem of extending to continuous time the ideas first encountered in a discrete-time set-up . The Black-Scholes model is covered in detail and particular emphasis is placed on learning to adapt it to new situations . This model building provides a "know-how and skill" element to a module which is otherwise mostly of "knowledge" type. The end of semester examination will be of three-hour duration and will require students to answer all questions on the paper . | |||||||||||||||||||||||||||||||||||||||||||||

1. Demonstrate an understanding of the fundamental concepts of the theory of stochastic processes in discrete time through examples and counter-examples 2. Use the Optional Stopping Theorem to establish properties of various hitting times 3. Solve simple stochastic differential equations 4. Prove the basic results of utility theory and solve Merton's problem for CRRA utilities 5. Prove Girsanov's Theorem an apply it to selected problems in continuous-time finance 6. Derive the Black-Scholes formula and apply the method to a variety of extensions of the basic problem | |||||||||||||||||||||||||||||||||||||||||||||
