Markov Processes in Finance

Course Description

This course will motivate a solid foundation in the theory of Markov processes with numerous applications in finance. Applications will be taken from: mortgage modeling, credit modeling, dynamic programming, Monte Carlo Markov chain and Hidden Markov Models. Theory will be taken from: stationary distributions, quasi-stationary distributions, absorption probabilities, convergence, statistical modeling, etc. We will focus will be primarily on finite Markov chains but also discuss various divergences from this type of model. The class will place emphasis on mathematics and statistical modeling.
