The Columbia Experimental Laboratory for the Social Sciences (CELSS) would like to invite you to participate in its activities. You can earn money, have fun, and help research, all at the same time!
To register click on http://orsee.econ.columbia.edu and follow the instructions there. Registration only means that you will be invited when a study is open to participants. Nothing more happens unless you choose to accept the invitation and sign up for that study. You can unsubscribe at any time by clicking on a link provided in your registration email, or by directly contacting the lab manager.
Experiments are paid, anonymous, and are held to a strict rule of non-deception. Participants typically find them fun and a good source of cash.
(If you want to know more about CELSS, a joint laboratory for Economics, Political Science, SIPA, and the Business School go to http://econ.columbia.edu/celss).
