Thanks for the endorsement. Are you aware that there is an instructor's manual available? Call Theresa Cohan at 201-592-2723, (Prentice Hall) and she'll send you a copy. Also, I have some simple lotus computer games that illustrate open access problems and incentive-based regulation issues which I would happy to send along if you are interested. Feedback is of course welcome. Your book, Unorthodox Marxism, was one that pushed me towards econ grad school 12 or so years ago. What goes around comes around.
