Center for Capital Flow Analysis
This site is sponsored by John Oswin Schroy, an investment banker who
specializes in Latin American and developing economies' capital
markets. He "became interested in developing the use of flow of funds
accounts as a way to explain supply and demand in securities markets."
This site takes data from the Federal Reserve's "Flow of Funds" and
provides analysis and interpretation of the data.
