Abstract
This paper describes a methodology to approximate a bivariate
Markov process by means of a proper Markov chain and presents possible financial
applications in portfolio theory, option pricing and risk management.
In particular, we first show how to model the joint distribution between market
stochastic bounds and future wealth and propose an application to large-scale
portfolio problems. Secondly, we examine an application to VaR estimation. Finally,
we propose a methodology to price Asian options using a bivariate Markov
process.
