A rich literature from the 1970s shows that as inflation expectations become more and more ingrained, monetary policy loses its stimulative effect. In the extreme, with perfectly anticipated inflation, there is no trade-off between inflation and output. A recent literature on the interest-rate...

Conventional wisdom suggests that medium-term money neutrality imposes strong limitations on the effects of monetary policy. The point of this paper is that models with medium- and long-term money neutrality are prone to generate non-existence of equilibria at the effective lower bound (ELB) on...

We propose a theory to explain why, and under what circumstances, a politician gives up rent and delegates policy tasks to an independent agency. We apply this theory to monetary policy by extending a standard dynamic ""New-Keynesian"" stochastic general equilibrium model. This model gives a new...

This paper examines the effects of quantitative easing implemented by the Bank of Japan (BoJ) since early 2001, looking specifically at the impact on inflation expectations and real asset prices. It suggests a number of possible channels through which quantitative easing may have exerted...

I model deflation, at zero nominal interest rate, in a microfounded general equilibrium model. I show that deflation can be analyzed as a credibility problem if the government has only one policy instrument, money supply carried out by means of open market operations in short-term bonds, and...
