INTEREST RATE EFFECTS OF DEMOGRAPHIC CHANGES IN A NEW KEYNESIAN LIFE-CYCLE FRAMEWORK

Interest rate effects of demographic change in a new-Keynesian life-cycle framework

This paper develops a small-scale DSGE model which embeds a demographic structure within a monetary policy framework. We extend the tractable, though non-monetary overlapping-generations model of Gertler (1999) and present a small synthesis model which combines the set-up of Gertler with a New Keynesian structure, implying that the short-run dynamics related to monetary policy are in line with ...

Interest Rate Pegs in New Keynesian Models∗

The conventional policy perspective is that lowering the interest rate increases output and inflation in the short run, while maintaining inflation at a higher level requires a higher interest rate in the long run. In contrast it has been argued that a Neo-Fisherian policy of setting an interest-rate peg at a fixed higher level will increase the inflation rate. We show that adaptive learning ar...

Reconsidering the Natural Rate Hypothesis in a New Keynesian Framework

This paper formulates a stylized New Keynesian model in which each individual firm can select the frequency of its price adjustments, and we demonstrate that the endogeneity of the contract structure has a dramatic impact on the magnitude of the aggregate effects of steady-state inflation. We start by analyzing the exact nonlinear properties of a benchmark economy with exogenous contract durati...

Deviations from Uncovered Interest Rate Parity: A Post Keynesian Explanation

Robust monetary policy in a New Keynesian mode lwith imperfect interest rate pass-through

We use robust control to study how a central bank in an economy with imperfect interest rate pass-through conducts monetary policy if it fears that its model could be misspecified. The effects of the central bank’s concern for robustness can be summarised as follows. First, depending on the shock, robust optimal monetary policy under commitment responds either more cautiously or more aggressive...
