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 results fails to provide a reason for private agents to pick a unique stable path. We propose a way...

In this thesis we try to understand the impact of some macroeconomic features of developing economies, in particular the existence of a large informal sector, on the reaction of these economies to different shocks. In order to achieve this objective, we derive a simple New Keynesian Small Open...

We study a flexible price IS/LM economy in which the money supply and interest rate play the role of monetary policy instruments. If the central bank sets the nominal interest rate, the ambiguity in the price level is manifested. However, the equilibrium price level is permissible, if the...

In a simple New Keynesian model, we derive a closed form solution for the inflation-gap persistence parameter as a function of the policy weights in the central bank’s Taylor rule. By estimating the time-varying weights that the FED attaches to inflation and the output gap, we show that the...

This paper examines the methods used by the Bank of Japan for the estimation of the output gap. Attention is paid to the real-time estimation problem. After reviewing the evolution of output gap estimation at the Bank, I discuss advantages and disadvantages of the various output gap measures....

In a simple New Keynesian model, we derive a closed form solution for the inflation-gap persistence parameter as a function of the policy weights in the central bank’s Taylor rule. By estimating the time-varying weights that the FED attaches to inflation and the output gap, we show that the...

In this paper we systematically evaluate how central banks respond to deviations from the inflation target. We present a stylized New Keynesian model in which agents' inflation expectations are sensitive to deviations from the inflation target. To (re-) establish credibility, monetary policy...
