In this paper we build a dynamic stochastic general equilibrium model of a small open monetary union with optimal monetary and fiscal policy, to study the transmission of country specific shocks and associated exchange rate fluctuations. We show that movements of the monetary union's exchange...

Contrary to widespread empirical evidence, standard NOEM models imply that the real exchange rate appreciates following an increase in public spending. This paper introduces productive government purchases and shows that the real exchange rate can depreciate after a positive spending shock, thus...

In this essay we study the optimal non-coordinated fiscal policy in a monetary union, where a common and independent monetary authority commits to optimally set the union-wide nominal interest rate. The national governments in the monetary union implement independent fiscal policies by choosing...

We lay out a tractable model for fiscal and monetary policy analysis in a currency union, and analyze its implications for the optimal design of such policies. Monetary policy is conducted by a common central bank, which sets the interest rate for the union as a whole. Fiscal policy is...

How does economic activity outside of government control-informality-affect the conduct of fiscal and monetary policy? I study this question in a New Keynesian, small open economy model. The model is assumed to feature informality in both goods and labor markets. A non-traded sector produces a...

To analyse the interdependence between monetary and fiscal policy during a financial crisis, we develop an open-economy DSGE model with monetary and fiscal policy as well as financial markets in a continuous-time framework based on stochastic differential equations. Monetary policy is modelled...

The monetary and fiscal policy interactions have gained a new research interest after the 2008 crisis due to the global increase of fiscal debt. This paper constructs a macroeconomic model of joint fiscal and monetary policy for an emerging open economy taking into account its structural...

In the aftermath of the global financial crisis, the state of macroeconomicmodeling and the use of macroeconomic models in policy analysis has come under heavy criticism. Macroeconomists in academia and policy institutions have been blamed for relying too much on a particular class of...

Membership in a currency union is not irreversible. Exit expectations may emerge during sovereign debt crises, because exit allows countries to reduce their liabilities through a currency redenomination. As market participants anticipate this possibility, sovereign debt crises intensify. We...

The last review of the ECB’s monetary policy strategy in 2003 followed a period of predominantly upside risks to price stability. Experience following the 2008 financial crisis has focused renewed attention on the question of how monetary and fiscal policy should best interact, in particular...
