This paper studies optimal financial policy in a world where the financial sector can become excessively optimistic. I decompose the welfare effects of bank capital regulation to demonstrate the effects of exuberance and its interaction with incentive problems in banking. The optimal policy...

This paper uses a dynamic panel approach to explain the determinants of widening sovereign bond yield spreads vis-à-vis Germany in selected euro area countries during the period end-July 2007 to end-March 2009, when the financial turmoil developed into a full-blown financial and economic...

Economic and Monetary Union (EMU) has transformed Europe and has created an integrated pan-European economy. Much research has focused on understanding this integration process and what benefits and costs it entails. This paper identifies a political economy channel of EMU as the monetary union...

How to conduct macro-prudential regulation? How to coordinate monetary policy and macro-prudential policy? To address these questions, I develop a continuous-time New Keynesian economy in which a financial intermediary sector is subject to a leverage constraint. Coordination between monetary and...

This paper identifies the various channels that give rise to a "sovereign-bank nexus" whereby the financial health of banks and sovereigns is intertwined. We find that banks and sovereigns are linked by three interacting channels: banks hold large amounts of sovereign debt; banks are protected...

We review the determinants of the discretionary fiscal policy action of governments in the euro area and in other advanced economies during the past 20 years. This is done by estimating fiscal reaction functions using dynamic panel techniques and country-by-country estimates. The results suggest...

The fiscal consolidation measures adopted in many euro area countries over 2010-13 reduced excessive domestic fiscal imbalances, but came at the cost of short-term output losses. This simultaneous tightening of fiscal policy raised concerns that such output losses might be exacerbated by...

This paper estimates a fiscal reaction function (FRF) framework for euro area countries and derives a novel approach to measure fiscal fatigue. As in previous studies, we find evidence that euro area sovereigns abide, on average, by (weak) sustainability constraints. The primary balance improves...
