CELSS uses the Online Recruitment System for Economic Experiments (ORSEE) software, a web-based Online Recruitment System, specifically designed for organizing laboratory experiments.

You can register to be a participant at C.E.L.S.S. and earn money while contributing to the advancement of social sciences by clicking here. You will join more than 1500 students and other members of the Columbia community who already registered.

You will be paid for your participation. Registering for an experiment and showing up at the time and date of the session guarantees a payment of $5 called “show-up fee”. Your final earnings depend on the outcome of the experiment.

When you are registered, you will receive emails anytime there is an experimental session opening for which you satisfy the experiment’s selection criteria.

If you have any question about registration, please contact the lab manager.

Researchers can contact the lab manager to register as experimenters on our recruitment system.
