Money and Credit Market Integration in an enlarging Euro Zone: Methodological Issues
Johannes Stephan, Jens Hölscher
European Economic Policies - Alteratives to Orthodox Analysis and Policy Concepts,
2006
Abstract
“The chapter discusses methodological issues of money and credit market integration within the context of an enlarging Euro area. Common methods of interest parity tests are rejected in favour of a comparison of nominal interest rates. Hölscher and Stephan find that from an institutional point of view the new EU member countries look under-banked, whereas interest rates are converging. As policy implication the paper argues for a Euro adoption of the new EU members rather sooner than later.“

Excess Volatility in European Equity Style Indices - New Evidence
Marian Berneburg
IWH Discussion Papers,
No. 16,
2006
Abstract
Are financial markets efficient? One proposition that seems to contradict this is Shiller’s finding of excess volatility in asset prices and its resulting rejection of the discounted cash flow model. This paper replicates Shiller’s approach for a different data set and extends his analysis by testing for a long-run relationship by means of a cointegration analysis. Contrary to previous studies, monthly data for an integrated European stock market is being used, with special attention to equity style investment strategies. On the basis of this analysis’ results, Shiller’s findings seem questionable. While a long-run relationship between prices and dividends can be observed for all equity styles, a certain degree, but to a much smaller extent than in Shiller’s approach, of excess volatility cannot be rejected. But it seems that a further relaxation of Shiller’s assumptions would completely eliminate the finding of an overly strong reaction of prices to changes in dividends. Two interesting side results are, that all three investment styles seem to have equal performance when adjusting for risk, which by itself is an indication for efficiency and that market participants seem to use current dividend payments from one company as an indication for future dividend payments by other firms. Overall the results of this paper lead to the conclusion that efficiency cannot be rejected for an integrated European equity market.

Economies of Scope in European Railways: An Efficiency Analysis
Christian Growitsch, Heike Wetzel
IWH Discussion Papers,
No. 5,
2006
Abstract
In the course of railway reforms in the end of the last century, national European governments, as well the EU Commission, decided to open markets and to separate railway networks from train operations. Vertically integrated railway companies – companies owning a network and providing transport services – argue that such a separation of infrastructure and operations would diminish the advantages of vertical integration and would therefore not be suitable to raise economic welfare. In this paper, we conduct a pan-European analysis to investigate the performance of European railways with a particular focus on economies of vertical integration. We test the hypothesis that integrated railways realise economies of joint production and, thus, produce railway services on a higher level of efficiency. To determine whether joint or separate production is more efficient we apply a Data Envelopment Analysis super-efficiency bootstrapping model which relates the efficiency for integrated production to a virtual reference set consisting of the separated production technology. Our findings are that in a majority of European Railway companies exist economies of scope.

The unemployment-growth relationship in transition countries
Hubert Gabrisch, Herbert Buscher
IWH Discussion Papers,
No. 5,
2005
Abstract
Does the disappointingly high unemployment in Central and East European countries reflect non-completed adjustment to institutional shocks from transition to a market economy, or is it the result of high labour market rigidities, or rather a syndrome of too weak aggregate demand and output? In the case of transitional causes, unemployment is expected to decline over time. Otherwise, it would pose a challenge to the European Union, particular in case of accession countries, for it jeopardizes the ambitious integration plans of, and may trigger excessive migration to the Union. In order to find out which hypothesis holds 15 years after transition has started, we analyze the unemploymentgrowth dynamics in the eight new member countries from Central-Eastern Europe. The study is based on country and panel regressions with instrument variables (TSLS). The results suggest to declare the transition of labour markets as completed; unemployment responds to output and not to a changing institutional environment for job creation. The regression coefficients report a high trend rate of productivity and a high unemployment intensity of output growth since 1998. The conclusion is that labour market rigidities do not to play an important role in explaining high unemployment rates. Rather, GDP growth is dominated by productivity progress, while the employment relevant component of aggregate demand is too low to reduce substantially the high level of unemployment.

The integration of imperfect financial markets: Implications for business cycle volatility
Claudia M. Buch, C. Pierdzioch
Journal of Policy Modeling,
No. 7,
2005
Abstract
During the last two decades, the degree of openness of national financial systems has increased substantially. At the same time, asymmetries in information and other financial market frictions have remained prevalent. We study the implications of the opening up of national financial systems in the presence of financial market frictions for business cycle volatility. In our empirical analysis, we show that countries with more developed financial systems have lower business cycle volatility. Financial openness has no strong impact on business cycle volatility, in contrast. In our theoretical analysis, we study the implications of the opening up of national financial markets and of financial market frictions for business cycle volatility using a dynamic macroeconomic model of an open economy. We find that the implications of opening up national financial markets for business cycle volatility are largely unaffected by the presence of financial market frictions.

Financial Openness and Business Cycle Volatility
Claudia M. Buch, Jörg Döpke, C. Pierdzioch
Journal of International Money and Finance,
No. 5,
2005
Abstract
This paper discusses whether the integration of international financial markets affects business cycle volatility. 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. Empirical evidence supports this conclusion. Our results also show that the link between business cycle volatility and financial openness has not been stable over time.

Quality of Service, Efficiency, and Scale in Network Industries: An Analysis of European Electricity Distribution
Christian Growitsch, Tooraj Jamasb, Michael Pollitt
IWH Discussion Papers,
No. 3,
2005
Abstract
Quality of service is of major economic significance in natural monopoly infrastructure industries and is increasingly addressed in regulatory schemes. However, this important aspect is generally not reflected in efficiency analysis of these industries. In this paper we present an efficiency analysis of electricity distribution networks using a sample of about 500 electricity distribution utilities from seven European countries. We apply the stochastic frontier analysis (SFA) method on multi-output translog input distance function models to estimate cost and scale efficiency with and without incorporating quality of service. We show that introducing the quality dimension into the analysis affects estimated efficiency significantly. In contrast to previous research, smaller utilities seem to indicate lower technical efficiency when incorporating quality. We also show that incorporating quality of service does not alter scale economy measures. Our results emphasise that quality of service should be an integrated part of efficiency analysis and incentive regulation regimes, as well as in the economic review of market concentration in regulated natural monopolies.

Network Access Charges, Vertical Integration, and Property Rights Structure
Christian Growitsch, Thomas Wein
Energy Economics,
No. 2,
2005
Abstract
After the deregulation of the German electricity markets in 1998, the German government opted for a regulatory regime called negotiated third party access, which would be subject to ex post control by the federal cartel office. Network access charges for new competitors are based on contractual arrangements between energy producers and industrial consumers. As the electricity networks are incontestable natural monopolies, the local and regional network operators are able to set (monopolistic) charges at their own discretion, limited only by their concerns over possible interference by the federal cartel office (Bundeskartellamt). In this paper we analyse if there is evidence for varying charging behaviour depending on a supplier`s economic independence (structure of property rights) or its level of vertical integration. For this purpose we hypothesise that incorporated and vertically integrated suppliers set different charges than independent utility companies. Multivariate estimations show a relation between network access charges and the network operator’s economic independence as well as level of vertical integration. On the low voltage level, for an estimated annual consumption of 1700 kW/h, vertically integrated firms set – as predicted by our hypothesis - significantly lower access charges than vertically separated suppliers, whereas incorporated network operators charge significantly higher charges compared to independent suppliers. There is insufficient evidence available to confirm these results for other consumptions or voltage levels.

Determinants and Effects of Foreign Direct Investment: Evidence from German Firm-Level Data
Claudia M. Buch, J. Kleinert, A. Lipponer
Economic Policy,
No. 41,
2005
Abstract
Foreign direct investment is an essential aspect of ‘globalization’ yet its empirical determinants are not well understood. What we do know is based either on poor data for a wide range of nations, or good data for the US and Swedish cases. In this paper, we provide evidence on the determinants of the activities of German multinational firms by using a newly available firm-level data set from the Deutsche Bundesbank. The specific goal of this paper is to demonstrate the relative role of country-level and firm-level determinants of foreign direct investment. We focus on three main questions: First, what are the main driving forces of German firms’ multinational activities? Second, is there evidence that sector-level and firm-level factors shape internationalization patterns? Third, is there evidence of agglomeration effects in the foreign activities of German firms? We find that the market access motive for internationalization dominates. Firms move abroad mainly to gain better access to large foreign markets. Cost-saving motives, however, are important for some manufacturing sectors. Our results strongly suggest that firm-level heterogeneity has an important influence on internationalization patterns – as stressed by recent models of international trade. We also find positive agglomeration effects for the activities of German firms that stem from the number of other German firms that are active on a given foreign market. In terms of lessons for economic policy, our results show that lowering barriers to the integration of markets and encouraging the formation of human capital can promote the activities of multinational firms. However, our results related to the heterogeneity of firms and agglomeration tendencies show that it might be difficult to fine-tune policies directed at the exploitation of synergies and at the creation of clusters of foreign firms.

Cross-border Banking and Transmission Mechanisms in Europe: Evidence from German Data
Claudia M. Buch
Applied Financial Economics,
No. 16,
2004
Abstract
International activities of commercial banks play a potential role for the transmission of shocks across countries. This paper presents stylized facts of the integration of European banking markets and analyses the potential of banks to transmit shocks across countries. Although the openness of banking systems has increased, bilateral financial linkages among EU countries are relatively small. The exceptions are claims of German banks on a number of smaller countries. These data are used for an analysis of the determinants of cross-border lending patterns.
