  1. 10 minutes overview to z-tree

  2. Outline of Presentation • What is z-tree? • What can it do? • How does it work? • When to use? • Alternatives? • A quick demo

  3. An Introduction to Z-Tree • Z-Tree is a free program used for conducting experiments. • It has its own programming language (similar to C) • Software Tutorial and Reference Manual available at http://www.iew.unizh.ch/ztree/index.php • Also check out the Course Website.

  4. Z-Tree Software Features of Z-Tree include: • communication between the computers; • increased participation; • data saving; • less mistakes; • time management; • real-time info dissemination & analysis; • compute statistics (eg: profit);

  5. Subject PCs How does it work? Zleaf.exe Subject’s inputs Zleaf.exe Experimentor PC Zleaf.exe Ztree.exe Auction.ztt Zleaf.exe Experimental data Zleaf.exe Hard drive or server Instructions, Parameters, results, Zleaf.exe

  6. Quick notes… • Ability to simulate z-tree and multiple copies of z-leaf on your laptop • Ability to change the default language

  7. Alternatives to Z-tree • Paper and Pen • MS Excel (shared workbook feature) • MS Access

  8. How easy is it to program in z-tree? Z-tree website claims: • “A public good experiment, for instance, can be programmed within an hour, a double auction within a day.”

  9. When to use z-tree • Is the experiment sufficiently complicated (can “paper and pen” work?) • MS Excel (robustness issue) • Suggestion – use default templates with some “paper and pen” • Dealing with “common knowledge” and “random choices”
