Stochastic Processes for Finance and Economics

Introduksjon

Stochastic processes play a fundamental role in modeling uncertain phenomena in business and economics. In an era where understanding risk is paramount, these mathematical models allow us to quantify and navigate complex, seemingly random market parameters. Today, stochastic methods serve as the backbone for critical financial activities, ranging from the valuation of assets and pricing of insurance products, to interest rate forecasting and optimization under uncertainty.

The main objectives of this course are to provide a solid basis for the mathematical models used to describe financial uncertainty. Students will be introduced to the foundations of probability theory and stochastic processes. To support this theoretical learning, the course will utilize Python for simple simulations. This is not intended to build advanced programming skills, but rather to help students visualize the behavior of stochastic processes and gain intuition through practical examples.
