I build a quantitative two-country DSGE model of the European Union (EU) and investigate whether there are welfare gains from fiscal policy cooperation between the new EU members and the euro area (EMU). Fiscal cooperation is defined in terms of joint maximization of the weighted average of...

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...

Many economists are convinced that longer-term benefits from fiscal consolidation are in a trade-off with short-term deceleration in output growth. However, more recent research suggests that curbing fiscal imbalances contributes to faster growth already in the short term. This paper is about...

We investigate which variables have supported growth in the euro area over the last 30 years. This is a challenging task due to dimensionality problems: a large set of potential determinants, limited data, and the prospect that some variables could be non-stationary. We assemble a set of 35...

We provide evidence that industries' supply curves are convex. To guide our empirical analysis, we develop a model, in which capacity constraints at the plant level generate convex supply curves at the industry level. The industry's capacity utilization rate is a sufficient statistic for the...

This paper compares the role of monetary and fiscal policy shocks in advanced and emerging economies. Using a model with a hierarchical structure we capture the variability of GDP response to policy shocks both between and within the groups of advanced and emerging countries. Our results provide...

We study optimal monetary and fiscal policy in a New Keynesian model where occasional declines in agents' confidence can give rise to persistent liquidity trap episodes. Unlike in the case of fundamental-driven liquidity traps, there is no straightforward recipe for mitigating the welfare costs...

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 develops a tractable model of a monetary union with a sound fiscal governance structure and shows how in such environment the design of monetary policy above and at the lower bound constraint on short-term interest rates can be linked to well-known findings from the literature dealing...
