To Michael Nuwer,
     I do not think the econophysics movement looks much like the usual 
"economic imperialism,"
which traditionally involved going into sociology or political science or 
wherever and, a la, Gary
Becker, imposing the homogeneous rational agent model on their topics.  This 
may be a bit more
like Kahnemann and Tversky, coming writing papers on econ topics while 
formally staying in psychology.
One difference is that while a small amount of this econophysics stuff is 
being published in economics
journals, the vast majority of it continues to be appearing in physics 
journals not even indexed in the
JEL, and thus basically outside the consciousness of all but a few 
economists.  Some of this also
reflectst the much longer lag times involved in getting a paper refereed and 
published in economics
journals compared to physics (and other hard science) journals, where the 
social norms are much
more socially responsible than they have been in economics.  Lots of 
physicists say "I don't want to
waste my time with your journals and their long lags."
      Most of the papers that have appeared in economics journals have 
involved an economist (or
two) as a coauthor, and as more of this coauthoring and collaboration 
occurs, we may see more of
this work showing up in the economics journals.
