The following links are to various applets I have developed for economics and econometrics classes. More should appear in the near future. If you are an instructor and you would like to use any of them for a class, you are invited to do so. If you do, I only ask that you:

(1) include the appropriate attribution. Some applets have an information button. In such cases, provision of a fully operational applet is sufficient. If the applet does not include an information button, please include the following statement (or its informational equivalent) somewhere in the surrounding html: "This applet written by Geoffrey Gerdes."

(2) tell me you are using it. Suggestions to improve the applets are encouraged as well. Please send an e-mail to I hope you enjoy them!

Ready for use

Working demo, but not finished for various reasons
