Jim,

Are you sure that you are not an economist? (Only an economist would intend that question as a compliment but that is my intention!). Empirical researchers and graduate students should take note of your last post because you have given them plenty of grist for the mill.

I often tell my students to evaluate literatures not papers because no single paper is definitive. Truth emerges more slowly through the give and take of the scientific process. I think we have seen some of that process in action with this week's debate. I've certainly learned a lot and am always delighted to come away with more ideas for future papers. Thanks!
