I am trying something new which may not work, but it's worth a try. I have added a second comment link with the title "Technical Comments" to each post. I'm hoping to encourage a wider range of participation, particularly from people interested in the core economic issues surrounding a particular post (both theoretical and empirical).
I am going to moderate the comments in the new thread with a heavy hand and keep the discussion at the level you would find in the classroom or in a seminar. The idea is to promote a respectful interchange among people with some formal training in the area and in doing so, get participation from people who might not otherwise leave a comment. As far as I'm concerned, nothing is too technical. Clarifications, qualifications, extensions, links to related academic work (your own work included), debates about the technical merits of claims in a post, anything along those lines is welcome. [I have asked that people leave their names, and that is preferred, but pseudonyms are allowable if you identify yourself in an email.]
This is not intended to substitute for the regular comments which are unmoderated for the most part (though there are limits), and nothing will change there. It's intended to serve as a complement that (hopefully) brings about a wider range of participation and more discussion on substantive economic issues. I don't expect that there will be such a discussion with every post, or even that the discussions will be all that common, but hopefully there will be times when a debate on the more technical issues will take place. That would be nice, and I encourage those of you who have studied the economic issues related to things posted here to share what you know with the rest of us.
