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.

Longterm development of return on assets – an empirical panel data analysis

Wirtschaft im Wandel,
No. 5,

Abstract
Eine der grundlegenden Aussagen der ökonomischen Theorie ist die Behauptung, daß Wettbewerb keine dauerhaften über- und unterdurchschnittlichen Renditen zuläßt. Wie kann jedoch ein dauerhafter Übergewinn eines Monopolisten von einem Innovationsgewinn unterschieden werden? In welchen Märkten sollte regulierend eingegriffen werden? Das dynamische Wettbewerbskonzept betrachtet im Gegensatz zur statischen Betrachtung explizit den zeitlichen Verlauf von Gewinnen und Renditen. Ein Unternehmer kann durch neue Produkte oder neue Produktionsprozesse einen Vorteil gegenüber seinen Wettbewerbern erzielen. Daraus entstehende Innovationsgewinne dienen wiederum als Anreiz für Imitatoren, sich dieser Entwicklung anzuschließen, was zu einer Verringerung der Übergewinne führt. Übergewinne stehen damit keinesfalls im Widerspruch zu einem funktionierenden Wettbewerb. Der vorliegende Beitrag untersucht auf Basis von Jahresabschlüssen deutscher Unternehmen die Entwicklung von Gesamtkapitalrenditen im zeitlichen Verlauf. Es soll untersucht werden, ob der von Schumpeter vermutete Anpassungsprozeß, der über- und unterdurchschnittliche Gewinne hin zu einem langfristigen Niveau angleicht, bestätigt werden kann und wie schnell ein derartiger Anpassungsprozeß abläuft. Für die mittleren Branchenrenditen des Produzierenden Gewerbes ist eine Konvergenz hin zu einem langfristigen Niveau festzustellen. Innerhalb dieses Prozesses werden im Mittel 40% der Abweichung vom langfristigen Niveau innerhalb eines Jahres abgeschmolzen. Bei der Betrachtung der Unternehmensrenditen konnten jedoch langfristig Unterschiede nachgewiesen werden. Für Unternehmen war die Anpassungsrate mit 50% im Vergleich zu den Branchenwerten deutlich höher. Bei der Betrachtung des Zusammenhanges zwischen der Anpassungsrate und dem langfristigen Renditeniveau auf Unternehmensebene zeigt sich, daß Unternehmen, die überdurchschnittlich starken Wettbewerbskräften ausgesetzt sind, ein höheres langfristiges Renditeniveau aufweisen als andere. Agieren Unternehmen in Märkten mit einem hohen Wettbewerbsdruck, erzielen sie keineswegs unter-, sondern vielmehr langfristig deutlich überdurchschnittlichen Renditen.

Does Transparency of Central Banks produce Multiple Equilibria on Currency Markets?
Axel Lindner
Scandinavian Journal of Economics,
No. 1,
2006
Abstract
A recent strand of literature shows that multiple equilibria in models of markets for pegged currencies vanish if there is slightly diverse information among traders; see Morris and Shin (2001). It is known that this approach works only if the common knowledge in the market is not too precise. This has led to the conclusion that central banks should try to avoid making their information common knowledge. We develop a model in which more transparency of the central bank implies better private information, because each trader utilises public information according to her own private information. Thus, transparency makes multiple equilibria less likely.

Forced to Freedom? Empirical Relations between Aid and Economic Freedom
Tobias Knedlik, Franz Kronthaler
IWH Discussion Papers,
No. 8,
2006
Abstract
The paper explores the relationships between economic freedom on the one side and development aid and IMF credit as approximation for conditional aid on the other side. After a short review of current literature on the issue of economic development, economic freedom, aid, and IMF credit, the paper develops a simple panel regression model to evaluate the relationship between “economic freedom” as dependent variable and “aid” and “IMF credit” as independent variables. The estimation is based upon data taken from the World Bank’s World Development Indicators and the Heritage Index of Economic Freedom. In contrast to previous research, our results allow the rejection of the hypothesis that IMF credit increases economic freedom and that aid is not contributing to economic freedom. The estimation results suggest that, firstly, aid is positively correlated with economic freedom, and secondly, that IMF credit is negatively correlated with economic freedom. Taking IMF credit as proxy for conditional aid, we conclude that for the period of observation it could not be shown that countries can be forced to economic freedom by aid conditions.

Network Investment and the Threat of Regulation – Preventing Monopoly Exploitation or Infrastructure Construction?
Ulrich Blum, Christian Growitsch, Niels Krap
IWH Discussion Papers,
No. 7,
2006
Abstract
In summer 2005, the German telecommunication incumbent Deutsche Telekom announced its plans to build a new broadband fibre optics network. Deutsche Telekom decided as precondition for this new network not to be regulated with respect to pricing and third party access. To develop a regulator's strategy that allows investments and prevents monopolistic prices at the same time, we model an incumbent's decision problem under a threat of regulation in a game-theoretical context. The decision whether to invest or not depends on the probability of regulation and its assumed impact on investment returns. Depending on the incumbent's expectation on these parameters, he will decide if the investment is favourable, and which price to best set. This price is below a non-regulated profit maximising price, since the incumbent tries to circumvent regulation. Thus, we show that the mere threat of a regulator's intervention might prevent supernormal profits without actual price regulation. The regulator, on the other hand, can influence both investment decision and the incumbent's price via his signals on regulation probability and price. These signals an be considered optimal, if they simultaneously allow investment and minimize the incumbent's price.

Progressivity and Flexibility in Developing an Effective Competition Regime: Using Experiences of Poland, Ukraine, and South Africa for developing countries
Franz Kronthaler, Johannes Stephan
IWH Discussion Papers,
No. 6,
2006
Abstract
The paper discusses the role of the concept of special and differential treatment in the framework of regional trade agreements for the development of a competition regime. After a discussion of the main characteristics and possible shortfalls of those concepts, three case countries are assessed in terms of their experience with progressivity, flexibility, and technical and financial assistance: Poland was led to align its competition laws to match the model of the EU. The Ukraine opted voluntarily for the European model, this despite its intense integration mainly with Russia. South Africa, a developing country that emerged from a highly segregated social fabric and an economy dominated by large conglomerates with concentrated ownership. All three countries enacted (or comprehensively reformed) their competition laws in an attempt to face the challenges of economic integration and catch up development on the one hand and particular social problems on the other. Hence, their experience may be pivotal for a variety of different developing countries who are in negotiations to include competition issues in regional trade agreements. The results suggest that the design of such competition issues have to reflect country-particularities to achieve an efficient competition regime.

A Game Theoretic Analysis of the Conditions of Knowledge Transfer by New Employees in Companies
Sidonia vonLedebur
IWH Discussion Papers,
No. 3,
2006
Abstract
The availability of knowledge is an essential factor for an economy in global competition. Companies realise innovations by creating and implementing new knowledge. Sources of innovative ideas are partners in the production network but also new employees coming from another company or academia. Based on a model by HECKATHORN (1996) the conditions of efficient knowledge transfer in a team are analysed. Offering knowledge to a colleague can not be controlled directly by the company due to information asymmetries. Thus the management has to provide incentives which motivate the employees to act in favour of the company by providing their knowledge to the rest of the team and likewise to learn from colleagues. The game theoretic analysis aims at investigating how to arrange these incentives efficiently. Several factors are relevant, especially the individual costs of participating in the transfer. These consist mainly of the existing absorptive capacity and the working atmosphere. The model is a 2x2 game but is at least partly generalised on more players. The relevance of the adequate team size is shown: more developers may increase the total profit of an innovation
(before paying the involved people) but when additional wages are paid to each person a greater team decreases the remaining company profit. A further result is
that depending on the cost structure perfect knowledge transfer is not always best for the profit of the company. These formal results are consistent with empirical studies to the absorptive capacity and the working atmosphere.

New orientations for the German spatial development policy? Report about a workshop with the IWH

No. 2,

Abstract
Seit kurzem ist eine intensive Diskussion zur Frage im Gange, ob es bei der Raumentwicklungspolitik, also bei Politikmaßnahmen, mit denen bestimmte Regionen gezielt unterstützt werden, eine Neuorientierung zugunsten wachstumsstarker Regionen geben sollte. Daran schließt sich dann die zweite Frage an, ob und welche Unterstützung künftig die strukturschwachen, peripher gelegenen Regionen erhalten sollten. Die knappen öffentlichen Kassen, der verschärfte Wettbewerb der Regionen in Europa und die veränderten Bedingungen für die öffentliche Daseinsvorsorge in Räumen mit dramatischen Bevölkerungsrückgängen drängen nach Antworten auf die genannten Fragen. Das IWH bearbeitet zusammen mit der Gesellschaft für Finanz- und Regionalanalysen (GEFRA), Münster, und dem Leibniz Institut für Regionalentwicklung und Strukturplanung (IRS), Erkner, im Auftrag des Bundesamtes für Bauwesen und Raumordnung ein Forschungsprojekt zum Thema „Bundesstaatliche Ordnung und Bedeutung finanzieller Ausgleichssysteme für die Raumordnung“, das empirische Fundierungen zur Beantwortung der o. g. Fragen liefern soll. In der ersten Phase der Projektbearbeitung fand am 21. Juni 2005 ein Workshop statt, der den politischen Status quo räumlicher Ausgleichspolitik und eine Bestandsaufnahme vorliegender Forschungsergebnisse zum Gegenstand hatte. Eine stärkere Orientierung auf die wachstumsstarken Räume könnte bedeuten, an dort gegebenen Agglomerationsvorteilen anzuknüpfen bzw. Agglomerationsnachteile zu mildern. Für die Unterstützung von Agglomerationseffekten, denen in modernen regionalökonomischen Theorien große Bedeutung als Entwicklungsdeterminante beigemessen wird, liefert allerdings die empirische Forschung bislang wenig Hinweise, die in konkrete regionalpolitische Maßnahmen umzusetzen wären. Es wurde grundsätzlich von den meisten Referenten und Teilnehmern betont, daß auch bei einer stärkeren Hinwendung zu einer wachstumsorientierten Raumentwicklungspolitik die strukturschwachen peripheren Räume nicht ihrem Schicksal überlassen werden dürften. Die Zentren müssten Verantwortung für die schwächere Peripherie übernehmen, den schwachen Regionen sollte Hilfe zur Selbsthilfe gewährt werden, und ein Überdenken der Daseinsvorsorge in Räumen mit starkem Bevölkerungsrückgang wird unvermeidlich sein.

Determinants of employment - the macroeconomic view
Christian Dreger, Heinz P. Galler, Ulrich (eds) Walwai
Schriften des IWH,
No. 22,
2005
Abstract
The weak performance of the German labour market over the past years has led to a significant unemployment problem. Currently, on average 4.5 mio. people are without a job contract, and a large part of them are long-term unemployed. A longer period of unemployment reduces their employability and aggravates the problem of social exclusion.
The factors driving the evolution of employment have been recently discussed on the workshop Determinanten der Beschäftigung – die makroökonomische Sicht organized jointly by the IAB, Nuremberg, and the IWH, Halle. The present volume contains the papers and proceedings to the policy oriented workshop held in November 2004, 15-16th. The main focus of the contributions is twofold. First, macroeconomic conditions to stimulate output and employment are considered. Second, the impacts of the increasing tax wedge between labour costs and the take home pay are emphasized. In particular, the role of the contributions to the social security system is investigated.
In his introductory address, Ulrich Walwei (IAB) links the unemployment experience to the modest path of economic growth in Germany. In addition, the low employment intensity of GDP growth and the temporary standstill of the convergence process of the East German economy have contributed to the weak labour market performance. In his analysis, Gebhard Flaig (ifo Institute, München) stresses the importance of relative factor price developments. A higher rate of wage growth leads to a decrease of the employment intensity of production, and correspondingly to an increase of the threshold of employment. Christian Dreger (IWH) discusses the relevance of labour market institutions like employment protection legislation and the structure of the wage bargaining process on the labour market outcome. Compared to the current setting, policies should try to introduce more flexibility in labour markets to improve the employment record. The impact of interest rate shocks on production is examined by the paper of Boris Hofmann (Deutsche Bundesbank, Frankfurt). According to the empirical evidence, monetary policy cannot explain the modest economic performance in Germany. György Barabas and Roland Döhrn (RWI Essen) have simulated the effects of a world trade shock on output and employment. The relationships have been fairly stable over the past years, even in light of the increasing globalization. Income and employment effects of the German tax reform in 2000 are discussed by Peter Haan and Viktor Steiner (DIW Berlin). On the base of a microsimulation model, household gains are determined. Also, a positive relationship between wages and labour supply can be established. Michael Feil und Gerd Zika (IAB) have examined the employment effects of a reduction of the contribution rates to the social security system. To obtain robust results, the analysis is done under alternative financing scenarios and with different macroeconometric models. The impacts of allowances of social security contributions on the incentives to work are discussed by Wolfgang Meister and Wolfgang Ochel (ifo München). According to their study, willingness to work is expected to increase especially at the lower end of the income distribution. The implied loss of contributions could be financed by higher taxes.
