This is the documentation site for the American Economic Association’s registry for randomized controlled trials.

Randomized Controlled Trials (RCTs) are widely used in various fields of economics and other social sciences. As they become more numerous, a central registry that lists which trials are ongoing, complete, or withdrawn becomes important for various reasons, including, but not limited to, serving as a source of results for meta-analysis and as a one-stop resource to find out about available survey instruments and data.

Because existing registries were not well suited to the need for social sciences, in April 2012, the AEA executive committee decided to establish such a registry for economics and other social sciences.

If you are running or have run a trial: Registration is free and you do not need to be a member of the AEA to register. We encourage you to register any new study at its outset. However, given the backlog of existing trials, we invite you to also register past studies. If your trial is registered before the start of its intervention, we also encourage you to consider preparing a submission for pre-results review at the Journal of Development Economics before beginning data collection.

If you are searching for results: Please browse the database. More results are always forthcoming!
