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...

This paper uses the EAGLE, a multi-country dynamic general equilibrium model, to illustrate dynamic adjustments in a small open economy undergoing real convergence. We consider the effects of productivity catch-up and misperceptions about future productivity developments. Our results indicate...

Dynamic stochastic general equilibrium models have recently become standard tools for policy-oriented analyses. Nevertheless, their forecasting properties are still barely explored. We fill this gap by comparing the quality of real-time forecasts from a richly-specified DSGE model to those from...

We determine optimal monetary policy under commitment in a forwardlooking New Keynesian model when nominal interest rates are bounded below by zero. The lower bound represents an occasionally binding constraint that causes the model and optimal policy to be nonlinear. A calibration to the U.S....

We determine optimal discretionary monetary policy in a New-Keynesian model when nominal interest rates are bounded below by zero. Nominal interest rates should be lowered faster in response to adverse shocks than in the case without bound. Such ‘preemptive easing’ is optimal because...

We show how to use a simple perturbation method to solve non-linear rational expectation models. Drawing from the applied mathematics literature we propose a method consisting of series expansions of the non-linear system around a known solution. The variables are represented in terms of their...

This paper investigates the impact on the network growth of the level of merchant discount, the level of Multilateral Interchange Fee (MIF), and the consumers' and the merchants' awareness of positive network effects. In an artificial market, in which issuers and acquirers belong to the same...

Phenomena such as the Great Moderation have increased the attention of macro-economists towards models where shock processes are not (log-)normal. This paper studies a class of discrete-time rational expectations models where the variance of exogenous innovations is subject to stochastic regime...

We revisit recent evidence on how monetary policy affects output and prices in the U.S. and in the euro area. The response patterns to a shift in monetary policy are similar in most respects, but differ noticeably as to the composition of output changes. In the euro area investment is the...
