Imposing the natural rate hypothesis (NRH) can dramatically alter the determinacy bounds on monetary policy by closing … the output gap in the long run. I show that the hypothesis eliminates any role for the output gap in determinacy and … renders the conditions for determinacy identical for all conforming supply equations. Specializing further to IS demand …

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...

We argue that it is not necessary for the central bank to react to the exchange rate to have a desirable outcome in the economy. Indeed, when the Taylor rule includes contemporane-ous data on the variables in the rule, the central bank can disregard from the exchange rate as long as there is...
