Topics in Probability Theory and Stochastic Processes

BEA513 Topics in Probability Theory and Stochastic Processes

Autumn 2024

  • Topics

    This course is an introductory course in stochastic analysis and focuses on developing students’ knowledge and understanding of dynamic systems. Static models generally fail to explain changes in the economy, and the time development of dynamical systems is crucial to understand how and why systems change. Geometric Brownian motion and the Ornstein-Uhlenbeck process are widely used in applications of this theory, and the students should be familiar with the construction of these processes. The part of stochastic analysis covered in this course, is a prerequisite for many different topics in economics and management science, and is a must for studies in mathematical finance

    Topics covered:

    1. Basic properties of Brownian motion
    2. Numerical simulation of Brownian motion
    3. Calculating expected values related to Brownian increments
    4. Filtrations and filtered information
    5. Stochastic integrals
    6. Numerical simulations of stochastic integrals
    7. The Ito formula
    8. Geometric Brownian motion
    9. The Ornstein-Uhlenbeck process
    10. Numerical schemes for stochastic differential equations
    11. Calculating conditional expectations
    12. Applications to continuous time newsvendor models
