We analyse the stability of countries within a monetary union in the face of asymmetric shocks, using a simple but widely applicable model. We show that members of the union may be subject to severe, and possibly unstable, cycles following asymmetric shocks if there is a significant backward...

It is commonly asserted that monetary and fiscal policy may have to be coordinated if they are to provide a nominal anchor and avoid the pathological outcomes of sunspots or explosive price paths. In this paper, we study a model in which government bonds are an imperfect substitute for money in...

Motivated by the recent experience of the U.S. and the Eurozone, we describe the quantitative properties of a New Keynesian model with a zero lower bound (ZLB) on nominal interest rates, explicitly accounting for the nonlinearities that the bound brings. Besides showing how such a model can be...

This paper examines how supply-side policies may play a role in fighting a low aggregate demand that traps an economy at the zero lower bound (ZLB) of nominal interest rates. Future increases in productivity or reductions in mark-ups triggered by supply-side policies generate a wealth effect...

Using data for the G7 countries, conditional correlations of employment and productivity are estimated, based on a decomposition of the two series into technology and non-technology components. The picture that emerges is hard to reconcile with the predictions of the standard real business cycle...

This paper reviews the recent literature on monetary policy rules. We exposit the monetary policy design problem within a simple baseline theoretical framework. We then consider the implications of adding various real world complications. Among other things, we show that the optimal policy...

Understanding the features and the determinants of individual price setting behaviour is important for the formulation of monetary policy. These behavioural mechanisms play a fundamental role in influencing the characteristics of aggregate inflation and in determining how monetary policy affects...

We examine the role of money in three environments: the New Keynesian model with separable utility and static money demand; a nonseparable utility variant with habit formation; and a version with adjustment costs for holding real balances. The last two variants imply forward-looking behaviour of...

The time series fit of dynamic stochastic general equilibrium (DSGE) models often suffers from restrictions on the long-run dynamics that are at odds with the data. Relaxing these restrictions can close the gap between DSGE models and vector autoregressions. This paper modifies a simple...

This paper reviews Bayesian methods that have been developed in recent years to estimate and evaluate dynamic stochastic general equilibrium (DSGE) models. We consider the estimation of linearized DSGE models, the evaluation of models based on Bayesian model checking, posterior odds comparisons,...
