This paper takes a welfare-view on eastern enlargement of the EU, focusing on incumbent countries. Enlargement is decomposed into three elements: Single-market integration on commodity markets, budgetary costs from EU-expenditure policies, and singlemarket-induced migration from new to present...

In diesem Beitrag folgen wir der aktuellen Diskussion über die Aussagekraft der Maastricht-Kriterien für die Auswahl von Ländern zur Teilnahme an der EWU. Es wird gezeigt, daß diese Kriterien weder die Theorie optimaler Währungsgebiete ausreichend reflektieren noch der...

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...

The desirability of flexible exchange rates is a central tenet in international macroeconomics. We show that, with forward-looking staggered pricing, this result crucially depends on the monetary authority's ability to commit. Under full commitment, flexible exchange rates generally dominate a...

The reduction in barriers to trade within the European Union has had important but disputed effects on inward direct investment. On the one hand, fears have been expressed that the Union could become a "Fortress Europe", with foreign firms effectively excluded from the internal market. On the...

It is conventionally held that countries are worse off by forming a monetary union when it comes to macroeconomic stabilization. However, this conventional view relies on assuming that monetary policy is conducted optimally. Relaxing the assumption of optimal monetary policy not only uncovers...

Whether countries benefit from forming a monetary union depends critically on the way monetary policy is conducted. This is mainly because monetary policy determines whether and to what extent a flexible nominal exchange rate fosters or hampers macroeconomic stabilization, even if monetary...

This paper discusses whether the integration of international financial markets affects business cycle fluctuations. In the framework of a new open economy macro-model, we show that the link between financial openness and business cycle volatility depends on the nature of the underlying shock....

This paper uses a dynamic general equilibrium two-country optimizing sticky-price model to analyze the consequences of international financial market integration for the propagation of asymmetric productivity shocks in a monetary union. The model implies that business cycle volatility is higher...

We derive the optimal exchange rate policy for a small open economy subject to terms-oftrade shocks. Firm owners and workers are risk averse but workers more so. Wages are given or partially indexed in the short run, and capital markets are imperfect. The government sets the exchange rate to...
