Government and NGO Reports

Most government agencies and NGOs have a "Publications" section on their website.  Find government agencies here and other antitrust organizations here.

FTC "For the Consumer" Monthly Newsletter
This monthly newsletter presents rather technical information that seems geared just as much to professionals as it is to consumers.  It contains a listing of all the activities and reports that the FTC has accomplished or published in the last month.  It serves as a very good place to check in to see what new reports and publications the FTC has recently made available to the public. 

Department of Justice Newsletters and Workloads
Newsletters as well as workload statistics as far back as 1970 and appropriations data back to 1903.

World Economic Forum Global Competitiveness Report
Each year the WEF conducts a survey of over 12,000 business executives  (Executive Opinion Survey) on competition conditions in their country (for instance firm concentration), as well as gathers its own data, which then form the basis of this annually-published Report.  The Report has a section on the state of competition.  Statistics can be arranged and compared country-by-country.
