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...

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...

We consider the effect of an increase in public investments on output in Europe against the background of a sharp drop of public investments in a number of EU countries during the crisis and subsequent policy discussions on the need to stimulate public investments. We start with a brief overview...

Fiscal policy constitutes a key tool for business cycle stabilisation next to monetary policy. In this context, having a well-suited macroeconomic model for analysing fiscal policy at a central bank is of primary importance. This paper documents the fiscal block of the ECB-BASE, which is a...

We revisit the so-called "secular international problem", whereby the adjustment of current account imbalances purportedly falls entirely on the shoulders of deficit countries. We introduce a stylised model to rationalise an asymmetric counter-cyclical policy reaction that is stronger for...

This paper studies stabilisation in a multi-country currency union of small open economies. It abstracts from key factors favouring currency union formation, such as reduced transaction costs and enhanced credibility, which are exogenous to the factors studied here. Demand-side shocks hamper...

In this paper, we examine the macroeconomic effects of alternative fiscal consolidation policies in the New Area-Wide Model (NAWM), a two-country open-economy model of the euro area developed at the European Central Bank (cf. Coenen et al., 2007). We model fiscal consolidation as a permanent...

In this paper, we study Ramsey-optimal fiscal and monetary policy in a mediumscale model of the U.S. business cycle. The model features a rich array of real and nominal rigidities that have been identified in the recent empirical literature as salient in explaining observed aggregate...

This paper develops a dynamic stochastic general equilibrium model with nominal rigidities, capital accumulation and finite lifetimes. The framework exhibits intergenerational wealth effects and is intended to investigate the macroeconomic implications of fiscal policy, which is specified by...

The monetary integration of the acceding countries will proceed in several distinct steps, starting with membership in the European Union (EU), followed by participation in the so-called Exchange Rate Mechanism (ERM) II and ultimately entry into the euro area. This paper addresses the question...
