This guy Dave Smith at EconLog posted the following citation:
==> Krugman, Paul (1994), ‘Past and Prospective Causes of High Unemployment’, Federal Reserve Bank of Kansas City, Economic Review, Fourth Quarter, 23-43.
That looks like it could be the gift that keeps on giving. However, when I tried to get it, I could only find the article summary online. I tried emailing the KC Fed but haven’t heard back. Can any of you sleuths find it? The website made it look like you could download the whole issue, but I couldn’t get it to work.
