It appears this Daniel Kuehn is very well researched in his analysis and replies. He and “Lord Keynes” provide harsh critiques of Bob Murphy’s and Tom’s writings on the Depression of 1920 on this page of Murphy’s site: http://consultingbyrpm.com/blog/2012/10/krugman-on-the-1920s-a-one-act-play.html
Hopefully Tom and Bob will respond with full force? It’s hard for a rookie like myself to sift through all of their empirical claims.
