Regional origins of employment volatility: evidence from German states
Claudia M. Buch
CES IFO Working Paper No. 2296,
2008
Abstract
Greater openness for trade can have positive welfare effects in terms of higher growth. But increased openness may also increase uncertainty through a higher volatility of employment. We use regional data from Germany to test whether openness for trade has an impact on volatility. We find a downward trend in the unconditional volatility of employment, paralleling patterns for output volatility. The conditional volatility of employment, measuring idiosyncratic developments across states, in contrast, has remained fairly unchanged. In contrast to evidence for the US, we do not find a significant link between employment volatility and trade openness.

Abstract
Recent diverging labour cost developments among EMU countries, affecting the trade and inflation position of each country, raise some doubts regarding the equal distribution of costs and benefits of shocks among the member countries and, hence, the long term stability of the Euro.

Oil Prices and International Trade: How Petrodollar Recycling Affects the Industrialised Countries
Götz Zeddies
Wirtschaft im Wandel,
No. 4,
2008
Abstract
In den zurückliegenden vier Jahren haben sich an den internationalen Rohstoffmärkten die Ölpreise ungefähr verdreifacht. Seit den Ölpreisschocks der 70er und 80er Jahre wurden zahlreiche empirische Analysen zu den makroökonomischen Wirkungen von Rohstoffpreissteigerungen durchgeführt, die auf eine zunehmende Gefahr der aktuellen Ölpreis-Hausse für Konjunktur und Wachstum in ölimportierenden Industrieländern schließen lassen. Allerdings werden darin die Rückwirkungen von Ölpreissteigerungen über den Außenhandel ölimportierender Länder, die, im Gegensatz zu den binnenwirtschaftlichen Effekten im Zuge der Globalisierung an Bedeutung gewonnen haben, nur unvollständig berücksichtigt. Dies betrifft insbesondere die verbesserte Einkommenssituation ölexportierender Länder, die ihre Erdöleinnahmen größtenteils in den entwickelten Industrieländern recyceln.
In der vorliegenden Analyse werden die Wirkungen von Ölpreissteigerungen auf die Warenexporte und -importe ölimportierender Industrieländer detailliert untersucht. Im Ergebnis zeigt sich, dass die dämpfenden Effekte bei den Warenausfuhren geringer ausfallen als bei den Wareneinfuhren. Während die Importnachfrage überproportional auf die Abschwächung der Konsum- und Investitionsnachfrage reagiert, stehen auf der Exportseite einer schwächeren Entwicklung der Ausfuhren in die Industrieländer hohe Exportzuwächse in die Ölförderländer gegenüber. Infolgedessen wird der negative Effekt von Ölpreisschocks auf Wachstum und Konjunktur in ölimportierenden Industrieländern vom Außenhandel über Verbesserungen der Außenbeiträge abgemildert, aber nicht kompensiert.

The European Emissions Trading System: What Have We Learned so Far?
Wilfried Ehrenfeld
Wirtschaft im Wandel,
No. 3,
2008
Abstract
Das IWH beschäftigt sich mit den Auswirkungen des CO2-Handels auf die betroffenen Unternehmen. Die erste Periode des europäischen Emissionshandelssystems war als Lernphase konzipiert. In dieser wurden zwei Probleme deutlich: Das erste und offensichtlichste war die Überausstattung mit Zertifikaten. Die Anreize, in die Vermeidung von CO2 zu investieren, können somit eher als gering betrachtet werden. Das zweite ergab sich aus der vollständig kostenfreien Zuteilung. Während Stromkunden die finanzielle Hauptlast zu tragen hatten, profitierten die Stromerzeuger, da offensichtlich die Zertifikatepreise als Opportunitätskosten in den Strompreis einkalkuliert wurden.
Die Analyse führt zu der Erkenntnis, daß es richtig war, auf Ebene der Europäischen Union die Zertifikatemenge für die zweite Handelsperiode zu kürzen und in der deutschen Gesetzgebung den Verkauf bzw. die Versteigerung eines Teils der Zertifikate zu verankern. Weiter kann die Vereinfachung des Zuteilungsverfahrens in Deutschland als Fortschritt betrachtet werden.

The Stability of Bank Efficiency Rankings when Risk Preferences and Objectives are Different
Michael Koetter
European Journal of Finance,
No. 2,
2008
Abstract
We analyze the stability of efficiency rankings of German universal banks between 1993 and 2004. First, we estimate traditional efficiency scores with stochastic cost and alternative profit frontier analysis. Then, we explicitly allow for different risk preferences and measure efficiency with a structural model based on utility maximization. Using the almost ideal demand system, we estimate input- and profit-demand functions to obtain proxies for expected return and risk. Efficiency is then measured in this risk-return space. Mean risk-return efficiency is somewhat higher than cost and considerably higher than profit efficiency (PE). More importantly, rank–order correlation between these measures are low or even negative. This suggests that best-practice institutes should not be identified on the basis of traditional efficiency measures alone. Apparently, low cost and/or PE may merely result from alternative yet efficiently chosen risk-return trade-offs.

Deeper, Wider and More Competitive? Monetary Integration, Eastern Enlargement and Competitiveness in the European Union
Gianmarco Ottaviano, Daria Taglioni, Filippo di Mauro
ECB Working Paper,
No. 847,
2008
Abstract
What determines a country’s ability to compete in international markets? What fosters the global competitiveness of its firms? And in the European context, have key elements of the EU strategy such as EMU and enlargement helped or hindered domestic firms’ competitiveness in local and global markets? We address these questions by calibrating and simulating a conceptual framework that, based on Melitz and Ottaviano (2005), predicts that tougher and more transparent international competition forces less productive firms out the market, thereby increasing average productivity as well as reducing average prices and mark-ups. The model also predicts a parallel reduction of price dispersion within sectors. Our conceptual framework allows us to disentangle the effects of technology and freeness of entry from those of accessibility. On the one hand, by controlling for the impact of trade frictions, we are able to construct an index of ‘revealed competitiveness’, which would drive the relative performance of countries in an ideal world in which all faced the same barriers to international transactions. On the other hand, by focusing on the role of accessibility while keeping ‘revealed competitiveness’ as given, we are able to evaluate the impacts of EMU and enlargement on the competitiveness of European firms. We find that EMU positively affects the competitiveness of firms located in participating economies. Enlargement has, instead, two contrasting effects. It improves the accessibility of EU members but it also increases substantially the relative importance of unproductive competitors from Eastern Europe. JEL Classification: F12, R13.

Determinants of International Fragmentation of Production in the European Union
Götz Zeddies
IWH Discussion Papers,
No. 15,
2007
Abstract
The last decades were characterized by large increases in world trade, not only in absolute terms, but also in relation to world GDP. This was in large parts caused by increasing exchanges of parts and components between countries as a consequence of international fragmentation of production. Apparently, greater competition especially from the Newly Industrializing and Post-Communist Economies prompted firms in ‘high-wage’ countries to exploit international factor price differences in order to increase their international competitiveness. However, theory predicts that, beside factor price differences, vertical disintegration of production should be driven by a multitude of additional factors. Against this background, the present paper reveals empirical evidence on parts and components trade as an indicator for international fragmentation of production in the European Union. On the basis of a panel data approach, the main explanatory factors for international fragmentation of production are determined. The results show that, although their influence can not be neglected, factor price differences are only one out of many causes for shifting production to or sourcing components from foreign countries.

Globalisation and Euro Area Trade: Interactions and Challenges
Filippo di Mauro, Ursel Baumann
ECB Occasional Paper,
No. 55,
2007
Abstract
As a major player in world trade, the euro area is strongly influenced by globalisation, but is far from being a passive spectator. The paper analyses how the euro area's trade specialization has changed in response to stronger international competition and the emergence of new global players, evaluating results and possible challenges ahead. The message remains mixed. On the positive side, the export specialisation of the euro area is increasing in some medium-high or high-tech sectors where productivity growth is strong and demand robust, such as pharmaceuticals, also by a more intensive recourse to importing intermediate goods from low-cost countries. On the other hand, in comparison to other industrialised economies, the euro area has been somewhat slower in moving towards research-intensive goods and away from labour-intensive sectors. While this could reflect data classification issues, it may also be a sign of structural rigidities in the euro area, which hinder adjustment processes.

Banks’ Internationalization Strategies: The Role of Bank Capital Regulation
Diemo Dietrich, Uwe Vollmer
IWH Discussion Papers,
No. 18,
2006
Abstract
This paper studies how capital requirements influence a bank’s mode of entry into foreign financial markets. We develop a model of an internationally operating bank that creates and allocates liquidity across countries and argue that the advantage of multinational banking over offering cross-border financial services depends on the benefit and the cost of intimacy with local markets. The benefit is that it allows to create more liquidity. The cost is that it causes inefficiencies in internal capital markets, on which a multinational bank relies to allocate liquidity across countries. Capital requirements affect this trade-off by influencing the degree of inefficiency in internal capital markets.
