Thanks for the links and the props–you are too kind. Re temporal specificities, Masten, Meehan, and Snyder introduced the term in 1991. I did expand on the concept in the 93 JLE paper, and showed how such specificities could create coordination problems unless markets were sufficiently “thick,” and that long term contracts or integration could economize on transactions costs in thin markets.

Thanks again, and keep up the good work on the blog.
