David Andolfatto, from the Research Division of the Federal Reserve Bank of St. Louis, summarizes the interesting work of Ostroy, Kocherlakota, Wallace and others, who highlight the role of money as a record keeping device. He then links this literature to my paper with L.H. White on Somalia. Since we here at TPS relish in shameless self-promotion, I thought I'd send this along.
Thanks to Andolfatto for linking to our paper!
