I'm glad that Barkley agrees with my point that we spend too much energy manipulating data relative to the emphasis would put on quality of data. I disagree with Barkley on the approach to econometrics. He says, if I understand him, we should begin with the theory and then test it. Tom Walker and I suspect that our tests will merely confirm our prior beliefs. I suspect that pure data mining might prove to be more fruitful, in the sense that it might alert us to unsuspected relationships. -- Michael Perelman Economics Department California State University Chico, CA 95929 Tel. 530-898-5321 E-Mail [EMAIL PROTECTED]
