- This is a very good idea; I do it too. On page 11 of my undergrad text I argue
- that turning 100 apartments into 100 condominiums has no effect on the rent
- for the remaining apartments. Most students find this surprising. There are
- many, many more examples like this in my book. (And in David Friedman's book,
- too, I hasten to add.)

- I also agree strongly. I've been doing a lot with symbolic math packages
- lately. For example, I wrote 25 Mathematica Notebooks to accompany my graduate
- textbook which are posted on MathSource. [To use MathSource, send e-mail to
- mathsource@wri.com with the message "help intro". You might also send another
- e-mail with the line "find economics" to find the Notebook I posted.]
- I also have edited a book called "Economic and Financial Modeling with
- Mathematica", TELOS/Springer-Verlag, 1993, ISBN 0-387-97882-8. This book
- contains a lot of research-oriented examples that are, I think, very
- stimulating.
-
- These are example of the use of computers at the graduate and postgraduate
- level. But I think that there are many promising applications at the undergrad
- level as well. For example, I'm now translating several workbook problems into
- Mathematica format and I'm going to try using these in the classroom next time
- I teach the course.
