I have posted a new discussion. It's on "Falling Behind the Curve: A Positive Analysis of Stop-Start Policies and the Great Inflation" by Andrew Levin and John B. Taylor presented at a recent conference at Norges Bank.
My paper "Estimated Interest Rate Rules: Do they Determine Determinacy Properties?" has been published in The B.E. Journal of Macroeconomics (Contributions). It can be accessed at the bepress site.
