Can students really learn economics from controlled laboratory experiments?

With increasing confidence, researchers in psychological economics have been able to demonstrate that in some situations, individuals do not behave like the homo economicus. Among some relevant attempts, Daniel Kahneman, along with his colleague Amos Tversky, pioneered the field of cognitive heuristics and biases in the late 1970s. Between 1971 and 1984, Kahneman and Tversky published a series of papers exploring the ways human judgment may be distorted when we are making decisions in conditions of uncertainty. Kahneman and Tversky’s book on this subject, Judgement Under Uncertainty: Heuristics and Biases, was too technical.  Daniel Kahneman’s book Thinking, Fast and Slow makes these essential ideas approachable for non-academic readers.

Kahneman won the Nobel Prize in Economics for the work on prospect theory that explains how people make decisions that involve risk of loss. Indeed, he has become notable for his work on the psychology of judgment and decision-making, behavioral economics and cognitive psychology.  In economic analysis, he introduced insights from cognitive psychology in order to highlight the human behavior under uncertainty. Specifically, his  research focuses on dismantling the rational decision maker known as homo economicus.

His research also shows that we have two sorts of thought processes: System 1 and System 2- intuition and reasoning. Intuition or System 1 is faster and has usually strong emotional bonds. It is based on habits that are very difficult to change or manipulate. Reasoning or System 2 turns out to be subject to conscious judgments and attitudes. As a result, System 2 thinks slowly; it considers, evaluates, reasons. However, for Kahneman, the main protagonist of human life is System 1: it is the agent of our automatic and effortless mental responses.

On behalf of the importance of System 1, Kahneman highlights the  predictable occurrance of errors of judgment. Indeed, he has cataloged people’s systematic mistakes and non-logical patterns for years on behalf of his belief on the relevance of unconscious errors of reasoning that distort our judgment of the world.

One of the main implications of his research is that the articulation between psychology and economics involves a methodological innovation. Kahnenam, as other researchers in experimental economics, has developed methods for thinking economic behavior in controlled laboratory experiments.

Considering the need to rethink the future of Economics Curriculum, one question still needs to be answered: Can students really learn economics from controlled laboratory experiments?

  1. I have been using experiments on Ultimatum Game and Trust in my classrooms. This makes classes more fun and interesting, and also demonstrate clearly the failure of economic theories to predict behavior correctly. I find that the students get more involved and engaged in the subject matter as a result. I have found the textbook Experimental Economics by Holt and Davis 1993 Princeton University Press to be very useful as a way to teach microeconomic concepts.

    Hi Asad,

    It would be interesting to deepen your comment on the textbook Experimental Economics. Considering this book, how do you turn out to teach microeconomic concepts?

  3. I had some correspondence with Sam Bowles about my survey of the evidence against neoclassical utility theory. He agreed that it provided evidence against how economists used these terms of utility maximization and rationality. Furthermore, he informed me about an international team that is trying to incorporate behavioral economics into microeocnomics. They have produced online teaching materials that are in use and available freely. I have not examined it myself, but it appears that this could be a useful approach:

    message from Sam Bowles:
    by the way, im producing (with a huge int’l team) a new intro to econ, that reflects much of what we have learned (including from beh econ) recently. its CORE curriculum online resources for economics: teaching economics as if the last 30 years had happened. check it out. core-econ.org
