Above is an example of a public good: the view of Mount Rainier. Below are some other public goods that I have tried to create, in defiance of all Samuelson conditions, and mostly because I got so many questions about them from colleagues that it saved me time to just put them online. Hopefully they are helpful for you.
Code for Making Maps in STATA
A number of people have asked me about making maps in STATA, which makes presentations more enjoyable and easy to understand; to this end, I have posted code to easily create maps by state and by county. Each zip-file includes a do-file, the map coordinates file, and the map data set. I also include a read-me file, and a sample dataset to use. Further instructions are enclosed in the do-file. Special thanks to Michel Grosz for beta-testing this small project for me. If you see any mistakes in my code, please let me know, and I will edit fix them.
Users Guide to MABLE/Geocorr
One tool I use a lot to create cross-walks between various geographic units, especially non-standard ones, is from University of Missouri's Census Data Center, and is called MABLE/Geocorr. I wrote a brief user's guide to help people use it quickly and to understand the quirks that I have encountered along the way. It is not in any way affiliated with the University of Missouri or Centers therein, but is meant to be a quick how-to if you need a cross-walk.
