Data sources

This page contains a partial recollection of sources for economic data in various forms. All of them are open-access and many offers interaction through APIs.

Besides these very useful and free datasets, there exists a number of database gathering observations at a very granular level. Usually administrative data are free but require a certain amount of paperwork because of the confidentiality issues that might arise; on the other hand there are private companies whose core business is gathering and selling data for a variety of purposes, like Bloomberg, Factset, Bureau van Dijk, Compustat, and so on. If you are lucky enough, your institution has a subscription to those companies and you can get to use their data. If you are really lucky, your institution has a subscription for Wharton Research Data Service, which basically gives access (and bulk download) to all such gated databases.
