The Reincarnation of Keynesian Economics

The title of this post is the title of a short, relatively obscure paper I wrote twenty years ago.  Here is the working paper version; here is the published (gated) version.  To my surprise, Paul Krugman cites it over at his blog, but Scott Sumner wonders whether Paul really read it.  In any event, it is delightful to see someone remember such an old paper.
