MA30089 Applied probability & finance

Credits: 6
Level: Honours
Semester: 2
Assessment: EX100
Before taking this unit you must take MA20036

Aims & Learning Objectives:
Aims: To develop and apply the theory of probability and stochastic processes to examples from finance and economics.
Objectives: At the end of the course, students should be able to
* formulate mathematically, and then solve, dynamic programming problems
* price an option on a stock modelled by a log of a random walk
* perform simple calculations involving properties of Brownian motion.
Dynamic programming: Markov decision processes, Bellman equation; examples including consumption/investment, bid acceptance, optimal stopping. Infinite horizon problems; discounted programming, the Howard Improvement Lemma, negative and positive programming, simple examples and counter-examples. Option pricing for random walks: Arbitrage pricing theory, prices and discounted prices as Martingales, hedging. Brownian motion: Introduction to Brownian motion, definition and simple properties. Exponential Brownian motion as the model for a stock price, the Black-Scholes formula.
