Kellogg has obtained a license for z-Tree (current version: 3.2.6). This license allows Kellogg researchers to conduct experiments within Kellogg's facilities only.


z-Tree (Zurich Toolbox for Readymade Economic Experiments) is a software package developed by Urs Fischbacher at the University of Zurich's Institute for Empirical Research in Economics to conduct economic experiments such as auctions, ultimatum games, prisoners' dilemma games, trust games, etc. Z-Tree has two components. The first is the z-Tree program itself, which controls the experiment, while the second is a client program called z-Leaf, which connects to the computer running z-Tree.
