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.

Technology spillovers from foreign investors in transition economies - are the effects still expected?
Jutta Günther
Economic and business review,
No. 1,
2005
Abstract
While it is widely acknowledged that there is a technology transfer from parent companies to foreign subsidiaries in central East European countries, there is no clear cut evidence for technology spillovers in favour of domestic companies so far. The paper presents a theoretical framework for how spillover mechanisms are turned into a reality and outlines empirical findings on technology spillovers for transition economies based on a comprehensive literature review. Against the background of an empirical qualitative study, the paper provides firm level explanations for the obvious lack of technology spillovers. Policy oriented issues will be discussed in the conclusions.

Evolving Structural Patterns in the Enlarging European Division of Labour: Sectoral and Branch Specialisation and the Potentials for Closing the Productivity Gap

IWH-Sonderhefte,
No. 5,
2003
Abstract
This report summarises the results generated in empirical analysis within a larger EU 5th FP RTD-project on the determinants of productivity gaps between the current EU-15 and accession states in Central East Europe. The focus of research in this part of the project is on sectoral specialisation patterns emerging as a result of intensifying integration between the current EU and a selection of six newly acceding economies, namely Estonia, Poland, the Czech and Slovak Republics, Hungary and Slovenia. The research-leading question is concerned with the role played by the respective specialisation patterns for (i) the explanation of observed productivity gaps and for (ii) the projection of future potentials of productivity growth in Central East Europe.
For the aggregated level, analysis determines the share of national productivity gaps accountable to acceding countries’ particular sectoral patterns, and their role for aggregate productivity growth: in Poland, the Slovak Republic and Hungary, sectoral shares of national productivity gaps are considerable and might evolve into a ‘barrier’ to productivity catch-up.Moreover, past productivity growth was dominated by a downward adjustment in employment rather than structural change. With the industrial sector of manufacturing having been identified as the main source of national productivity gaps and growth, the subsequent analysis focuses on the role of industrial specialisation patterns and develops an empirical model to project future productivity growth potentials. Each chapter closes with some policy conclusions.

Germany 2004: Only a transitory economic stimulus from moving tax cuts forward
Wirtschaft im Wandel,
No. 9,
2003
Abstract
In summer 2003 the German economy once again did not overcome the stagnation, which by now lasted three years. Only by the end of this year the German economy will begin to receive stronger support from a then further improved world economy. In the past months both US and European monetary policy have provided sufficient liquidity by lowering interest rates. In the USA, additional support is provided by fiscal policy; tax reductions and rebates increase domestic demand. Overall, Gross Domestic Product in the US will increase by 2.1% this year; in the euro area GDP will merely expand by a modest 0.8%. For Germany one of its key sectors will not be able to lift the economy as usual and GDP, when compared to last year, will only stagnate. Provided by the brought forward tax reform 2000 the coming year will begin with a stimulus to the German economy. The tax reductions, though, will have limited effect on aggregate production, as the increased consumption will not be able to stimulate investment. Accounting for calendar effects GDP in Germany will increase by at least 1% in 2004 compared with this year, but due to several additional working days in 2004, the unadjusted rate of expansion will be 1.7%. No substantial improvements are expected for the job market.

EU Eastern Enlargement and Structural Change: Specialization Patterns in Accession Countries and Economic Dynamics in the Single Market

Abstract
This paper analyses key issues of structural change and specialization patterns in the economies of an enlarged European Union. In all transition countries we observe a shift from the agricultural and industrial sector towards the service sector in terms of employment and productivity; however, in some countries a reindustrialisation drives is observed in a late transition stage. While some countries namely the Czech Republic, Hungary, Slovakia, Poland, Estonia and Slovenia, have improved their productivity especially in medium-technology-intensive industries and may advance on the technological ladder, others remain unchanged and seem to get locked in labour-intensive industrial sectors. In the context of EU-enlargement, we expect trade creation – going along with a rise of intra-industry trade – and higher FDI-activities. Countries will have to adjust along the logic of comparative advantage, however, technological upgrading and human capital formation are fields in which government can stimulate the direction of comparative advantage. According to the Gerschenkron-hypothesis the accession countries have an “advantage of backwardness. Since accession countries have a low R&D-GDP ratio in the early transition stage rising government expenditures on research and development plus higher education is crucial. We expect the EU-15 countries in general to benefit from enlargement but gains will be asymmetric across countries: economic geography matters. Austria, Germany, the Scandinavian countries, the Netherlands, Italy and France are likely to profit more than the other members of EU-15. Germany and Austria additionally play a particularly crucial role as origins of FDI. Future research should focus on the speed and the scope of structural adjustment.

Vertical and horizontal patterns of intra-industry trade between EU and candidate countries
Hubert Gabrisch
IWH-Sonderhefte,
No. 2,
2003
Abstract
Trade between the European Union (EU) and the Transition Economies (TE) is increasingly characterised by intra-industry trade. The decomposition of intra-industry trade into horizontal and vertical shares reveals predominantly vertical structures with decisively more quality advantages for the EU and less quality advantages for TE countries whenever trade has been liberalised. Empirical research on factors determining this structure in a EU-TE framework lags behind theoretical and empirical research on horizontal and vertical trade in other regions of the world. The main objective of this paper is therefore to contribute to the ongoing debate on EU-TE trade structures by offering an explanation of vertical trade. We utilise a cross-country approach in which relative wage differences, country size and income distribution play a leading role. We find first that relative differences in wages (per capita income) and country size explain intra-industry trade when trade is vertical and completely liberalised, and second that cross-country differences in income distribution play no explanatory role. We conclude that EU firms have been able to increase their product quality and to shift low-quality segments to TE countries. This may suggest a product-quality cycle prevalent in EU-TE trade.

Intra-industry trade and the productivity gap in the enlarged EU

Wirtschaft im Wandel,
No. 16,
2002
Abstract
Trade between the European Union (EU) and the Transition Economies (TE) is increasingly characterised by intra-industry trade. The decomposition of intra-industry trade into horizontal and vertical shares reveals predominantly vertical structures with decisively more quality advantages for the EU and less quality advantages for TE countries whenever trade has been liberalised. Sizeable foreign direct investment did obviously not reduce the superiority of producers in the EU in terms of technology, capital and human capital. The productivity gap between the EU and TE countries remains. EU firms have been able to increase their product quality and to shift low-quality segments of production to TE countries. This may suggest a product-quality cycle prevalent in EU-TE trade. The testing of this model confirms the assumptions.

FDI as Multiplier of Modern Technology in Hungarian Industry
Jutta Günther
Intereconomics,
No. 5,
2002
Abstract
Foreign direct investment is generally expected to play a significant role as a multiplier of modern production and management know-how in Central Eastern European transition economies. The following paper examines the various mechanisms by which such technological spillover effects could in theory take place and compares them with the results of an empirical study of their practical significance for Hungarian industry.

Germany s dependence on the economic situation in the U.S. is less crucial than generally assumed
Klaus Weyerstraß
Wirtschaft im Wandel,
No. 6,
2002
Abstract
In the context of the recent cyclical downturn in Germany it has often been argued that Germany depends more than other European countries on international economic developments. In this article it is investigated whether empirical support can be found for this proposition. Moreover, it is explored whether this relation has changed over time. For this purpose, vector autoregressive (VAR) models are applied to the output gaps of different economies.
It is shown that in the seventies and eighties, the transmission of business cycle shocks was more pronounced to Germany than to the other EU countries. Since the middle of the nineties, no such differences can be detected. Furthermore, since the middle of the nineties, the effects of shocks from abroad on the German business cycle have been significantly more short-lived than before.

The significance of FDI for innovation activities within domestic firms - The case of Central East European transition economies
Jutta Günther
IWH Discussion Papers,
No. 162,
2002
Abstract
Foreign direct investment is expected to play a significant role as a multiplier of modern production- and management-know-how in Central East European transition economies. The so-called technology-spillovers are explained through externalities or extra-marketlinkages. In practice they can take place via demonstration effects, labor mobility, supplier contacts, customer contacts or networking activities. However, the empirical study on the example of Hungarian industry shows that foreign owned and domestic firms – mainly due to their strong technological disparities – build virtually separate spheres within the industrial sector. Thus, technology-spillovers do hardly appear as an innovation-stimulating means for domestic companies.
