Causal Inference in Management and Economics Research

This two-day seminar provides an overview about methods for causal inference in empirical economic research. Starting with a general discussion about the concept of causality and its importance for addressing management and policy questions, it covers the most widely applied identification strategies in management, economics and computer science. Accompanying examples in Stata and R illustrate the discussed estimation techniques in a hands-on fashion. Due to its conceptual focus, the course is suitable for students with an intermediate level of knowledge in statistics and econometrics.

Causal Inference with Directed Acyclic Graphs

This workshop provides an introduction to causal inference with directed acyclic graphs (DAG). DAGs combine techniques from graph theory with statistical probability concepts and offer powerful tools for causal reasoning. Originally developed in the computer science and artificial intelligence field, the approach gets more and more traction in other disciplines too, such as epidemiology, sociology, finance, and economics. DAGs allow to check the identifiably of causal effects from observed data and lay bare the assumptions necessary for causal inference by relying on intuitive graphical criteria, which do not require a lot of algebra. As an encompassing framework for causal inference, DAGs also help to understand the identification arguments behind other popular estimation techniques such as regression, matching, instrumental variables and selection models. This workshop has no particular prerequisites. However, a good working knowledge in econometrics and probability theory is advantageous. (Slides, R code)
