In this paper we show that a money supply rule (a Taylor-type rule) and a Taylor rule produce substantial stochastic differences in the behavior of the economy. Hence it remains an open question whether one or other type of central bank behavior does a better job in welfare terms-contrary to a...

The Taylor rule is an incomplete description of monetary policy within a New Keynesian model. The NK model should be formulated with a money demand function and also embody a terminal condition on inflation explicitly designed to stop bubbles.

Forward-looking RE models such as the popular New Keynesian (NK) model do not provide a unique prediction about how the model economy behaves. We need some mechanism that ensures determinacy. McCallum (2012) says it is not needed because models are learnable only with the determinate solution...

The New-Keynesian Taylor-Rule model of inflation determination with no role for money is incomplete. As Cochrane (2007a) argues, it has no credible mechanism for ruling out bubbles and as a result fails to provide a reason for private agents to pick a unique stable path. We propose a way...

A recent paper by Ruge-Murcia [European Economic Review 48 (2004), 91-107] on asymmetric central bank objectives provides a new perspective on the policy roots of inflation in developed economies. More precisely, the paper demonstrates that if the distribution of the supply shocks is normal,...

This paper offers an alternative rationalization for opportunistic behaviour i.e., a gradual disinflation strategy where policymakers react asymmetrically to supply shocks, opting to disinflate only in recessionary period. Specifically, we show that adaptive expectations combined with asymmetry...
