Causal Machine Learning

In this course, students will learn about the chances and challenges of using machine learning techniques to identify causal effects. The course consists of three main parts. The first part provides an introduction to causality, the counterfactual framework, and specific classical methods for the identification of causal effects. The second part deals with basics in supervised machine learning and introduces various regularization methods as well as tree-based machine learning methods. The third part combines the first two parts by discussing how machine learning can contribute to the estimation and identification of causal effects. The lecture will be accompanied by a bi-weekly tutorial, in which students will learn how to implement the discussed methods in statistical software.
