How do we assess whether a school policy intervention has had the desired effect on student performance? How do we estimate the impact a natural disaster has had on the inhabitants of affected regions? How can we determine whether a change in the maximum speed on highways has lead to fewer accidents? These types of questions are at the core of many social scientific research problems. While questions with this structure are seemingly simple, their causal effects are notoriously hard to estimate, because often we cannot perform a randomized controlled experiment.
In this course, we will deal with several advanced methods for answering such questions, with a dual focus:
At the end of this workshop, participants have a firm grasp of the basics and limits of causal impact assessment, as well as the skills to start applying these methods in their own work.
