Doing Business
Got this link from Tim Harfords blog, named, what else, The Undercover Economist.
This world bank funded site, aptly named Doing Business, is a guide for evaluating regulations that directly impact economic growth, underlying laws, making cross-country comparisons, and identifying good practice reforms.
The site has a lot of downloadable reports, interactive maps, ranking simulators etc. Check it out. The interactive map of India and other countries is quite informative.
