Cours scientifiques - ECO533 : Probability theory for economics and finance

Domaine > Economie.

Descriptif

This course covers the foundational aspects of probability theory at the basis of economics and finance. The topics are standard for an introductory graduate probability course.

The course will last 18 hours and span 4 days. It will be divided into lectures of 4 and 4.5 hours. The first part is dedicated to constructing the notion of probability and random variables. Afterwards the course focuses on probability distributions: It discusses their measures of location and dispersion, such as expectation and variance, their common families, and transformation methods. The successive part of the course is dedicated to an advanced and thorough treatment of the topic of conditionality. The course concludes by presenting asymptotic results and convergence theorems for random variables on which econometrics (and statistical inference in general) is based.
