Major Changes in the Second Edition

Major changes in the second edition include:

• A new experiment on Network Externalities. In one session, students experience the onset of new communications technologies like e-mail and fax machines. A second session is devoted to competition between competing standards and the emergence of a dominant seller like Microsoft.
• Expanded discussion of essential economic concepts, including a new section devoted to summarizing these concepts.
• Answers to warm-up and discussion exercise questions are included in each chapter.
• A new format for the lab notes and homework that simplifies the amount of effort required by students and makes grading easier for the professor.
• Expanded discussion sections and a few fine-tuning modifications of the experiments.
• Improved format for the experimental materials, and new "quick-start" guides for each experiment.
