The European Emissions Trading System: What Have We Learned so Far?

No. 3,

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 Relationship between Knowledge Intensity and Market Concentration in European Industries: An inverted U-Shape
Niels Krap, Johannes Stephan
IWH Discussion Papers,
No. 3,
2008
Abstract
This paper is motivated by the European Union strategy to secure competitiveness for Europe in the globalising world by focussing on technological supremacy (the Lisbon - agenda). Parallel to that, the EU Commission is trying to take a more economic approach to competition policy in general and anti-trust policy in particular. Our analysis tries to establish the relationship between increasing knowledge intensity and the resulting market concentration: if the European Union economy is gradually shifting to a pattern of sectoral specialisation that features a bias on knowledge intensive sectors, then this may well have some influence on market concentration and competition policy would have to adjust not to counterfeit the Lisbon-agenda. Following a review of the available theoretical and empirical literature on the relationship between knowledge intensity and market structure, we use a larger Eurostat database to test the shape of this relationship. Assuming a causality that runs from knowledge to concentration, we show that the relationship between knowledge intensity and market structures is in fact different for knowledge intensive industries and we establish a non-linear, inverted U-curve shape.

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.

Geldpolitische Strategien im Umbruch
Diemo Dietrich, Albrecht F. Michler
Systeme monetärer Steuerung - Analyse und Vergleich geldpolitischer Strategien. Schriften zu Ordnungsfragen der Wirtschaft, Band 86,
No. 86,
2007
Abstract
Geldpolitische Strategien, insbesondere die der EZB, sind in jüngerer Vergangenheit verstärkt in den Fokus der öffentlichen und wissenschaftlichen Debatte gelangt. Nach einer Einführung in konzeptionelle Grundlagen geldpolitischer Strategien vergleicht die vorliegende Arbeit mit Inflationssteuerung und Geldmengensteuerung die beiden vorherrschenden geldpolitischen Stratgien. Kriterien sind hierbei unter anderem die Modellierung des Transmissionsmechanismus, die Rolle von Erwartungen, die Bedeutung nominaler Anker sowie Transparenz und Verantwortlichkeit. Den Abschluß bildet eine kritische Würdigung der aktuellen EZB-Strategie.

Cross-border Bank Contagion in Europe
Reint E. Gropp, M. Lo Duca, Jukka M. Vesala
ECB Working Paper, No. 662,
No. 662,
2006
Abstract
This paper analyses cross-border contagion in a sample of European banks from January 1994 to January 2003. We use a multinomial logit model to estimate the number of banks in a given country that experience a large shock on the same day (“coexceedances“) as a function of variables measuring common shocks and lagged coexceedances in other countries. Large shocks are measured by the bottom 95th percentile of the distribution of the daily percentage change in the distance to default of the bank. We find evidence in favour of significant cross-border contagion. We also find some evidence that since the introduction of the euro cross-border contagion may have increased. The results seem to be very robust to changes in the specification.

Vertical Intra-industry Trade between EU and Accession Countries
Hubert Gabrisch
IWH Discussion Papers,
No. 12,
2006
Abstract
The paper analyses vertical intra-industry trade between EU and Accession countries, and concentrates on two country-specific determinants: Differences in personal income distribution and in technology. Both determinants have a strong link to national policies and to cross-border investment flows. In contrast to most other studies, income distribution is not seen as time-invariant variable, but as changing over time. What is new is also that differences in technology are tested in comparison with cost advantages from capital/labour ratios. The study applies panel estimation techniques with GLS. Results show country-pair fixed effects to be of high relevance for explaining vertical intraindustry trade. In addition, bilateral differences in personal income distribution and their changes are positive related to vertical intra-industry trade in this special regional integration framework; hence, distributional effects of policies matter. Also, technology differences turn out to be positively correlated with vertical intra-industry trade. However, the cost variable (here: relative GDP per capita) shows no clear picture, particularly not in combination with the technology variable.

Enhanced Cooperation in an Enlarged EU, CeGE-Discussion Paper No. 53

Abstract
The paper adresses the need for more flexibility in the integration process of the European Union after its recent eastward enlargement. Due to the increasing number of decision-makers and the increasing heterogeneity of economic structures, financial constraints, societal preferences, and political interests, European integration based on the uniformity principle is hardly feasible. In order to avoid a rank growth of integration and yet to strengthen the momentum of flexibility, so-called enhanced cooperation appears to be an appropriate instrument to be applied to the overall integration process. In this context the paper analyzes different possible developments of selected common policies in the EU if enhanced cooperation is practised by a sub-group of EU-members. Based on cluster analysis similarities and distinctions among the EU members with respect to some specific policy realms are elaborated to identify clusters, or clubs, of countries which may apply the instrument of enhanced cooperation in the specific policy fields.
