i thought the point of this way, gee, the world bank makes it hard for you to get data out, so we scraped them, and here is the data for you guys to play around with. I looked for a bit, but couldnt find the data -- am I missing something?
However, this link
http://www.cgdev.org/section/publications?f[0]=field_documen...
leads to page that has two papers listed by title. Click the second of the papers. Click Data and Analysis tab, and you can download the CSV files they obtained. You don't need a log in but you do need to agree to sensible looking conditions.
I can't seem to link directly to the agree terms/download page.
