The Reform of Local Public Services of General Interest in Europe
Peter Haug, Martin T. W. Rosenfeld
Applied Economics Quarterly (Supplement),
2004
Abstract
The benefits of a reduced supply of local public services may more than outweigh the supposed welfare losses. This was suggested by various theoretical and empirical investigations in many fields of economics during the last decades. Nevertheless, local and national politicians, trade unionists, charities, and other lobbyists have succeeded in preventing further liberalisation of “services of general interest” in Europe. This article examines why these preserve agents have been and are still successful. The analysis is based on an institutional economic approach. Several policy measures and institutional changes are suggested to either reduce influence of preserve agents or to compensate them for their losses.

Firm-Specific Determinants of Productivity Gaps between East and West German Industrial Branches
Johannes Stephan, Karin Szalai
IWH Discussion Papers,
Nr. 183,
2003
Abstract
Industrial productivity levels of formerly socialist economies in Central East Europe (including East Germany) are considerably lower than in the more mature Western economies. This research aims at assessing the reasons for lower productivities at the firm level: what are the firm-specific determinants of productivity gaps. To assess this, we have conducted an extensive field study and focussed on a selection of two important manufacturing industries, namely machinery manufacturers and furniture manufacturers, and on the construction industry. Using the data generated in field work, we test a set of determinant-candidates which were derived from theory and prior research in that topic. Our analysis uses the simplest version of the matched-pair approach, in which first hypothesis about relevant productivity level-determinants are tested. In a second step, positively tested hypothesis are further assessed in terms of whether they also constitute firm-specific determinants of the apparent gaps between the firms in our Eastern and such in our Western panels. Our results suggest that the quality of human capital plays an important role in all three industrial branches assessed. Amongst manufacturing firms, networking activities and the use of modern technologies for communication are important reasons for the lower levels of labour productivity in the East. The intensity of long-term strategic planning on behalf of the management turned out to be relevant only for machinery manufacturers. Product and process innovations unexpectedly exhibit an ambiguous picture, as did the extent of specialisation on a small number of products in the firms’ portfolio and the intensity of competition.

Vertical and horizontal patterns of intra-industry trade between EU and candidate countries
Hubert Gabrisch
IWH-Sonderhefte,
Nr. 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 intraindustry trade when trade is vertical and completely liberalised, and second that crosscountry 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.

A revised theory of contestable markets : applied on the German telecommunication sector

Abstract
Despite the scepticism raised by the German Monopoly Commission our analysis shows that the revised theory of contestable markets can be applied to the telecommunications market better than expected. The original contestable market theory implied three assumptions necessary to be satisfied to establish potential competition: Free market entry, market exit is possible without any costs, and the price adjustment lag exceeds the entry lag. Our analysis shows that if the incumbent reduces its prices slowly (high adjustment lag) and the market entry can be performed quickly (low entry lag), a new competitor will be able to earn back sunk costs. Therefore it is not necessary that all three conditions are satisfied for potential competition to exist. We applied the ‘revised’ contestable market theory to the German telecommunication market and have been able to clearly identify the value added stages in which regulation is required. Under the present conditions local loops - which can be determined as natural monopolies - are not contestable due to sunk costs, high entry lags expected and a probable short price adjustment lag. Local loops can be identified as monopolistic bottlenecks therefore. Regional and local connection networks should also be regulated because a high entry lag and a low price adjustment lag have to be expected as well as current competition does not exist today. The national connection network shows current competition between several network providers; hence regulation can be abolished in this field. Assumed that network access is regulated, services can be supplied by several competing firms.

Intra-industry trade between European Union and Transition Economies. Does income distribution matter?
Hubert Gabrisch, Maria Luigia Segnana
IWH Discussion Papers,
Nr. 155,
2002
Abstract
EU-TE trade is increasingly characterised by intra-industry trade. For some countries (Czech Republic), the share of intra-industry trade in total trade with the EU approaches 60 percent. The decomposition of intra-industry trade into horizontal and vertical shares reveals overwhelming vertical structures with strong quality advantages for the EU and shrinking quality advantages for TE countries wherever trade has been liberalised. Empirical research on factors determining this structure in an EU-TE framework has lagged theoretical and empirical research on horizontal trade and vertical trade in other regions of the world. The main objective of this paper is, therefore, to contribute to the ongoing debate over EU-TE trade structures, by offering an explanation of intra-industry trade. We utilize a cross-country approach in which relative wage differences and country size play a leading role. In addition, as implied by a model of the productquality
cycle, we examine income distribution factors as determinates of the emerging
EU-TE structure of trade flows. Using OLS regressions, we find first, that relative
differences in wages (per capita income) and country size explain intra-industry trade, when trade is vertical and completely liberalized and second, that cross country differences in income distribution play no explanatory role. We conclude that if increasing wage differences resulted from an increasing productivity gap between highquality and low-quality industries, then vertical structures will, over the long-term create significant barriers for the increase in TE incomes and lowering EU-TE income differentials.

Attribute Dependence and the Provision of Quality
Hans Degryse, Andreas Irmen
Regional Science and Urban Economics,
Nr. 5,
2001
Abstract
Often a quality improvement necessitates modifications of varietal product features. This paper studies firms’ incentives to provide quality when this decision affects the goods’ degree of perceived horizontal differentiation. We find that the quality level hinges crucially on the interaction between the quality and the varietal product attribute. We examine the outcome of a game where firms decide on quality and price relative to what a social planner would desire. If the interaction between quality and perceived horizontal differentiation is sufficiently positive, we find for the sequential game ‘quality then price’ that the private incentives to provide quality are excessive relative to the social optimum. As a result the level and the direction of interaction between the attributes determines whether there is excessive or insufficient provision of quality.

A Glimpse on Sectoral Convergence of Productivity Levels
Gerald Müller
IWH Discussion Papers,
Nr. 133,
2001
Abstract
This paper examines the presence of sectoral convergence of labor productivity between 14 OECD countries. Using the OECD International Sectoral Data Base (ISDB), the paper looks at the developments within 12 distinct sectors during the period 1970-1995. The change of the coefficients of variance suggests that there is strong sectoral convergence within most service sectors while the evidence of convergence for Manufacturing as well as for Communication is rather weak. These findings are in line with most studies undertaken on this subject so far. It is concluded that economic theories at hand to explain growth and convergence (or divergence respectively) are of different importance for the sectors concerned. While models of the New Growth Theory seemed to be useful to explain growth mechanisms within Manufacturing and Communication, traditional models seemed to apply to most other sectors.

Environmental policy under product differentiation and asymmetric costs - Does Leapfrogging occur and is it worth it?
Jacqueline Rothfels
IWH Discussion Papers,
Nr. 124,
2000
Abstract
This paper studies the influence of environmental policies on environmental quality, domestic firms, and welfare. Point of departure is Porter’s hypothesis that unilateral environmental regulation may enhance the competitiveness of domestic firms. This hypothesis has recently received considerable support in theoretical analyses, especially if imperfectly competitive markets with strategic behavior on behalf of the agents are taken into account. Our work contributes to this literature by explicitely investigating the implications of asymmetric cost structures between a domestic and a foreign firm sector. We use a partial-equilibrium model of vertical product differentiation, where the consumption of a product causes environmental harm. Allowing for differentiated products, the domestic industry can either assume the market leader position or lag behind in terms of the environmental quality of the produced product. Assuming as a benchmark case that the domestic industry lags behind, we investigate the possibility of the government to induce leapfrogging of the domestic firm, i.e. a higher quality produced by the domestic firm after regulation than that of the competitor prior to regulation. It is shown that in the case of a cost advantage for the domestic firm in the production process the imposition of a binding minimum quality standard can serve as a tool to induce leapfrogging. In case of a cost disadvantage the same result can be achieved through an adequate subsidization of quality dependend production costs. Thus, careful regulation enables the domestic firm in both scenarios to better its competitive position against foreign competitors and to earn larger profits. Additionally, environmental quality and welfare can be enhanced.

Explaining Regional Disparities in Housing Prices across German Districts
Lars Brausewetter, Stephan L. Thomsen, Johannes Trunzer
IZA Institute of Labor Economics,

2022
Abstract
Over the last decade, German housing prices have increased unprecedentedly. Drawing on quality-adjusted housing price data at the district level, we document large and increasing regional disparities: growth rates were higher in 1) the largest seven cities, 2) districts located in the south, and 3) districts with higher initial price levels. Indications of price bubbles are concentrated in the largest cities and in the purchasing market. Prices seem to be driven by the demand side: increasing population density, higher shares of academically educated employees and increasing purchasing power explain our findings, while supply remained relatively constrained in the short term.
