<p>thanks for the link - but I have always had a dreadful time wading through economics papers, so I don’t think I have internalized it very well. One of the issues that I have with economically based modeling of human behavior is that, in my part of the country, I live with all those counter examples … including the husband who does astronomy (at a much lower rate of pay than nearly anything else he do) and the son that was so offended by Harvard’s marketing that it never even made the wish list pile.</p>
