Barkley Rosser writes: econometrics is usually not so oriented to stat significance. Much of this work is actually being done by physicists, now part of the so-called "econophysics" movement, although sometimes the ignorance of economics by these people can be annoying, especially when they start intoning about how they have solved all the problems of economics, when they have not read much literature and are talking about non-problems ... Chin up, Barkley, economists have offended too, with their talk about "the expanding domains of economics", the Max U behavior of bureaucrats, gravity models to explain urban location, public choice theory, etc. Perhaps this is all just atavistic tribal behavior, part of the human condition, more to be pitied than censured.
