This paper investigates the importance of ?scal policy in providing macroeconomic stabilisation in a monetary union. We use a microfounded New Keynesian model of a monetary union which incorporates persistence in in?ation and non-Ricardian consumers, and derive optimal simple rules for ?scal...

This paper studies the interactions of fiscal and monetary policies in the presence of fiscal spillovers within a monetary union. When capital markets are integrated, the fiscal policy of any member country will influence equilibrium wages and interest rates across the whole union. Thus there...

This paper analyses optimal discretionary non-coordinated monetary and fiscal stabilization policies in a micro-founded New-Keynesian model of a two-country monetary union with country-size asymmetry, under two policy scenarios. A balanced-budget policy scenario and a policy scenario where the...

Using stochastic simulations, this paper analyses the probability distribution of a country's deficit ratio under fixed exchange rates and a variety of monetary policy rules. The purpose is to show how the probability of getting an "excessive deficit", defined as a deficit / GDP ratio in excess...

The paper addresses the question what effects the enlargement of a monetary union will have on necessary structural reforms in the (low distortion) member countries and the (high distortion) candidate countries. While monetary union lowers reforms in the candidate countries, members of the...

We explore endogenous monetary unification in the context of a model in which a country with serious structural distortions (and, hence, high inflation) is admitted into a monetary union once its economic structure has converged sufficiently towards that of the existing participants. If...

Mitten in der Griechenland-Krise haben die Präsidenten der fünf wichtigsten europäischen Institutionen Vorschläge für eine weitere Integration der Europäischen Währungsunion unterbreitet. Sie beziehen sich dabei auf die Wirtschafts-, Finanzmarkt- und Bankenunion und gehen sogar so weit,...

This paper describes the institutional flaws that led to the euro crisis, assesses the institutional reforms that were put in place during and in the aftermath of the crisis, and evaluates the remaining fragilities of the architecture of the European monetary union. In mid-2017, growth in the...

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...

This paper explores the fiscal devaluation hypothesis in a model of a monetary union characterised by national fiscal and supranational monetary policy. We show that a unilateral tax shift towards indirect taxes in one of the countries produces small but non-negligible long-run effects on output...
