"Stepping on a Rake: the Fiscal Theory of Monetary Policy" is new paper, just published in the European Economic Review. This link gets you free access, but just for the next few days. After that, I can only post the last manuscript. (I held off sending this hoping the EER would fix the figure placement in the html version, but that didn't happen.)
The paper is about how the fiscal theory of the price level can describe monetary policy. Even without monetary, pricing, or financial frictions, the central bank can fix interest rates. In the presence of long-term debt higher interest rates lead to lower inflation for a while. Interest rate targets, forward guidance, and quantitative easing all work by the same mechanism. The paper also derives Chris Sims' "stepping on a rake" paper which makes that point, and integrates fiscal theory with a detailed new Keynesian model in continuous time.
