Course AbstractThis course is an introduction to the mathematical theory of derivative security (or option) pricing. Fundamental concepts are briefly introduced first using the discrete-time binomial model: financial markets, derivative securities, arbitrage, hedging and replicating portfolios, risk-neutral probabilities, risk-neutral pricing formula, and market completeness. Basic ideas of probability and stochastic processes are reviewed for finite probability spaces and discrete-time processes: conditional expectation, martingales, and Markov processes. After this introduction to finance using discrete-time models, the emphasis shifts to continuous-time models and the main part of the course. Topics covered include a summary of probability measure theory and conditional expectation, Brownian motion and quadratic variation, martingales, Ito integral, stochastic calculus, replicating portfolios and hedging, Black-Scholes-Merton formulae for a European-style call option price, change of measure and Girsanov's Theorem, risk-neutral pricing pricing theory, no-arbitrage and existence of risk-neutral measure, market completeness and uniqueness of risk-neutral measure, Markov property, Feyman-Kac theorem and the connection between stochastic calculus and partial differential equations, and local volatility and stochastic volatility models.
Pre-requisites and Co-requisitesOrdinary differential equations (01:640:244 or 01:640:252), multivariable calculus (01:640:251), linear algebra (01:640:250), and undegraduate probability theory with calculus (01:640:477 or 01:960:381). An undergraduate course on analysis (01:640:311-312 or 01:640:411-412) or engineering mathematics (01:640:421) or partial differential equations (01:640:423) is recommended but not required.
Please visit the prerequisites page for descriptions of Rutgers undergraduate course prerequisites. A solid understanding of undergraduate probability at the level of the textbook by Sheldon Ross, A First Course in Probability, is especially important. Given this background, the course should be accessible to Mathematical Finance master's degree students and graduate students in Computer Science, Economics, Finance, Engineering, Mathematics, Physics, Operations Research, and Statistics.
