GrantSelect This database is compiled by Oryx Press, and is said to
have some 10,000 funding opportunities by some 3,400
entities. A search for "economic" yielded 300 hits (even
though it was not one of their listed programs), and a quick
search showed that most seemed "reasonable." It is a fee-based
service, with rates from $350 to $1,500 for an institution.
They offer a 30-day free trial.
