Introduction

Bayesian econometrics offers a powerful alternative to classical econometric approaches, providing a framework for incorporating prior information and quantifying uncertainty in economic models. This course provides a comprehensive introduction to the theory and application of Bayesian methods in econometrics. Participants will learn the fundamental principles of Bayesian inference, including Bayes’ theorem, prior distributions, likelihood functions, and posterior distributions. The course will cover various techniques for specifying prior distributions, including informative and non-informative priors. Participants will also gain hands-on experience with Markov Chain Monte Carlo (MCMC) methods, which are essential for estimating Bayesian models. The course will emphasize the practical application of Bayesian methods to real-world economic problems. Participants will learn to use statistical software to implement Bayesian techniques and interpret the results in a meaningful way. By the end of the course, participants will have a solid understanding of Bayesian econometrics and be able to apply these methods to their own research and policy analysis.
