oTree Collection
Many people have started using oTree for running experiments in the lab, online, and even in the field. This is a small collection of apps, code snippets, and other oTree related tools that I find helpful. Note that many of items below come with a citation requirement. Feel free to e-mail me suggestions.
Apps
oTree sample apps are often forgotten, but include a large number of useful apps. These include: Bargaining Game, Bertrand Competition, Common Value Auction, Cournot Competition, Dictator Game (Kahneman et al., 1986), Guess 2/3 of the Average, Matching Pennies, Prisoners' Dilemma, two Public Good Games, Traveler's Dilemma (Basu, 1994), two Trust Games (Berg et al., 1995), and the Volunteer's Dilemma (Diekmann, 1985).
Many further apps have been developed by members of the community:
