AØKK08410U Field Experiments

Volume 2021/2022

Recent years have seen an enormous increase and interest in research using experimental methods in the field to address questions across a broad range of topics in economics and management:

  • Does Uber surge pricing work to steer demand?
  • What is the impact of microloans on alleviating poverty?
  • Do people eat more vegetarian food when it is on top of the menu?
  • Do people work harder when you pay them more?


Rather than trying to find already available data (which is often not possible) and inferring causality with advanced econometric methods, field experiments randomly assign units of observations to treatment and control conditions to identify causal effects. While the idea is simple, the implementation brings other challenges.


The course will teach the students how to design, implement, and analyse field experiments – also known as randomized controlled trials (RCT). It will show the potential gains from using field experiments to test economic theory, make causal inference, and inform optimal policies, both in the public and private sector.


Students will acquire the tools to successfully conduct their own field experiments and learn to critically evaluate experimental findings from the academic literature. Students will also explore the many challenges to implementing RCTs in the field and the tools to address these issues in study design and analysis.

Learning Outcome

After completing the course the student is expected to be able to:



  • Discuss state-of-the-art empirical research in experimental economics conducted in the field.
  • Identify research or policy questions that can be answered using field experiments.



  • Conduct power calculations for determening the correct sample size of an experiment.
  • Analyze experimental data using econometric tools.
  • Argue for optimal choice of outcome variables, sample size, clustering and randomization balancing.



  • Plan and develop a field experiment design, both conceptually for testing economic theory and practically.
  • Independently identify challenges that could arise when conducting an experiment and argue how to overcome them.
  • Initiate and participate in discussions of the implications of experimental results for policy makers or managements in the public and private sector.

The course will be based on a book, lecture slides, research papers, policy documents and survey articles. A detailed syllabus with required readings will be provided in Absalon the beginning of the course.


The following books and articles give an overview of the type of literature that will be used in class:

It is recommended to have followed the course "Applied Econometric Policy Evaluation" at the study of Economics, University of Copenhagen, or equivalent before or at the same time as the course.

The student will benefit from having attended a course on behavioral economics such as "Science of Behavior Change", the summer school "Behavioral Experimental Economics" or "The Psychology of Choice" at the study of Economics, University of Copenhagen, or equivalent before taking Field Experiments.
The format of the course is a combination of lectures and individual student work. The first eleven lectures will present core concepts, methods, and empirical results. Lecture number 12, 13 and 14 will consist of student presentations applying and critically reflecting on the learning of the lectures.

Student participation in all lectures will be expected and encouraged. An active discussion in class is essential for effective learning.
