Here is the Experiments with Economic Principles Web Site (now hosted at Ted's site).

New!  Electronic version of Experiments with Economic Principles (co-authored by Marcus Giametti, Humberto Llavador, John Miller, and Ted Bergstrom)

Most of the experiments in out text can now be run without paper.  Professrors Giametti and Llavador have written slick software that runs on students' cell phones or laptops, which tell them their experimental roles and where they can
enter their contracts after agreeing to a sale.  They have also adopted the  experimental instructions,  warm-up exercises, homework, and some discussion for web access.  The software records transaction prices and creates  spreadsheets showing the  results of the experiment.   Check this out at   at this website.
All of this is available  at no cost!
