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!
