Know when to expand your business:
The federal government offers numerous business opportunities to the public. Fed Biz Opps is the place to search for those opportunities. It is "the single government point-of-entry (GPE) for Federal government procurement opportunities over $25,000. Commercial vendors seeking Federal markets for their products and services can search, monitor and retrieve opportunities solicited by the entire Federal contracting community."
If you're interested in expanding into international trade, take a look at SBA's International Trade site to get useful information on the process.
STAT-USA also offers information on international trade opportunities as well as global market information for those doing business overseas. Though STAT-USA is a federal entity, it is for-profit and requires a password to be accessed. To use much of this site, you will need the help of the Government Documents Librarian to log-in.
To keep an eye on the national economy, you can use Economic Indicators. The site is a centralized location for accessing the daily updates of all 15 major economic indicators released by the Census Bureau and the Bureau of Economic Analysis.
You can also use the Consumer Price Index and the Producer Price Index. Each site offers quick access to the most commonly used tables and facts, specialized statistical tables, and the PDF versions of both monthly detailed reports.
Add Bureau of Economic Analysis for ability to track international to local economic statistics.
Another possible source is the Survey of Current Business. A federally created journal, it closely follows the current economic issues by providing "national, international, regional and industry estimates," discussing on-going innovations, and striving to keep users up-to-date on relevant BEA issues and initiatives.
