- This page was constructed for graduate students interested in the dynamics of the habit formation model analyzed in: Carroll, C. D., Overland, J., Weil, D. N., December 1997. Comparison utility in a growth model. Journal of Economic Growth 2 (4), 339-367. Carroll, C. D., Overland, J., Weil, D. N., June 2000. Saving and growth with habit formation. American Economic Review 90 (3), 341-355.

- If you use the resources made available here, please do send me an email. If you notice problems, please check your calculations with fellow students and if problems persist do inform me by email. Maple worsheets can be read only with the Maple software. Maple worksheets are unintelligble with a standard word processor. I provide below pdf versions of the Maple worksheet so that you may read the code without Maple. You will not be able to alter the pdf files, obviously, but you may be able to transcribe the lines of code into your own preferred software, such as Mathematica for instance. Do let me know if you do that.
