Replication in Behavioural Economics

December 15, 2022 at 12am Bogotá and New York/ 11am Wisconsin, USA/ 12am Pennsylvania, USA/ 5pm Lisbon/ 6pm Stockholm and Berlin/ 10:30pm New Dehli

ABSTRACT
I discuss several recent large replication projects in behavioral economics (psychology and economics), where my coauthors and I have redone experiments published in high impact journals with new and larger samples to see whether the main result replicates. We discuss the statistical power of these replications, since true original results might be exaggerated, which might make replications underpowered if we have high power to detect 100% of the original effect size. I briefly discuss our studies with prediction markets and forecasting surveys where researchers attempt to predict these replication outcomes. Finally, I discuss ways to increase the reliability of scientific results, and ways to avoid publication bias (with Registered Reports).

Please watch the pre-recorded video for this session here. The live session will then focus on discussion.
