This site was created in October 2001 as part of an exercise to illustrate the ease of creating Web-based teaching and learning material. An article on the basics of Web site creation for economists, based on a case study of the creation of this site, will appear in a future issue of Computers in Higher Education Economic Review (CHEER).
