Regional origins of employment volatility: evidence from German states
Claudia M. Buch
CES IFO Working Paper No. 2296,
2008
Abstract
Greater openness for trade can have positive welfare effects in terms of higher growth. But increased openness may also increase uncertainty through a higher volatility of employment. We use regional data from Germany to test whether openness for trade has an impact on volatility. We find a downward trend in the unconditional volatility of employment, paralleling patterns for output volatility. The conditional volatility of employment, measuring idiosyncratic developments across states, in contrast, has remained fairly unchanged. In contrast to evidence for the US, we do not find a significant link between employment volatility and trade openness.

Does too much Transparency of Central Banks Prevent Agents from Using their Private Information Efficiently?
Axel Lindner
IWH Discussion Papers,
No. 16,
2007
Abstract
This paper analyses in a simple global games framework welfare effects of different communication strategies of a central bank: it can either publish no more than its overall assessment of the economy or be more transparent, giving detailed reasons for this assessment. The latter strategy is shown to be superior because it enables agents to use private information and to be less dependent on common knowledge. This result holds true even if the strategies of agents are strategic complements, for which case it has been argued that too much transparency might induce agents to neglect their private knowledge.

Reform of Local Municipal Structures: Centralization not only Implicates Advantages
Peter Haug, Claus Michelsen
Wirtschaft im Wandel,
No. 11,
2007
Abstract
The question whether centralized or decentralized municipal structures are more efficient has been discussed, not only in Germany, for a long time primarily under aspects of law and administrative sciences. In this article, we use an economic approach instead. The prevailing theories on interjurisdictional competition are not conclusive about the cost and welfare effects of centralization. Therefore, using the example of Saxony-Anhalt we investigate empirically if there are any significant differences in expenses or personnel between more centralized municipal governance forms (“Einheitsgemeinden”) or rather decentralized forms (“Verwaltungsgemeinschaften”). Our cross-section analysis for selected municipal activities reveals that both types are very similar in their cost and manning structures. Significant differences can be explained rather by different population densities than by the organizational structure. Considering these results we do not recommend a forced amalgamation of the municipalities in Saxony-Anhalt. Especially, if frustration cost or the political transaction cost, which both rise with centralization, are taken into account.

Is a reduction of public holidays reasonable? A contribution to the economics of Sundays.
Lutz Schneider
Wirtschaftspolitik und wirtschaftliche Entwicklung. Analysen unter besonderer Berücksichtigung ostdeutscher Regionen,
2007
Abstract
Against the background of the debate on longer labour time the article analyses the welfare effects of public holiday reductions. He argues against this simple type of extensive growth policy, which neglects the beneficial implications of generally binding leisure times. Therefore the paper gives a contribution to the question of Sunday work and its external effects, which have to be considered, when the costs and benefits of such measures are calculated.

Armutsbekämpfung durch Einkommensumverteilung. Zu den Zielen und Finanzierungsproblemen eines Grundeinkommens
Ingmar Kumpmann
Berliner Debatte Initial Bd. 18 (2),
2007
Abstract
The basic income is introduced as a concept capable of improving inadequate poverty reduction schemes, especially by removing state controls of the ability and willingness to work. The welfare system will become more independent of wage-based social security contributions. The main challenge for the basic income model is financing. However, at the core of this challenge is not the question how large amounts of money can be raised, but rather the consequences for incentive mechanisms (and production). These are the limitations of the concept.

Die Gestaltung der Wirtschaftsstruktur durch das Land Brandenburg - Eine kritische Analyse der Subventionszahlungen für die CargoLifter AG
Mirko Titze
Forum der Forschung. Wissenschaftsmagazin der Brandenburgischen Technischen Universität Cottbus,
No. 17,
2004
Abstract
The Government of the State of Brandenburg subsidised the company CargoLifter AG on the basis of the „new industrial policy“. Following this policy the government supports individually selected industries or companies. The „new industrial policy“ is supported by the strategic trade policy, which states that subsidising domestic companies in incomplete markets with declining average costs and high entry barriers can increase the welfare level of a particular region. The following article provides an analysis whether in the case of Cargo-Lifter the Government of the State of Brandenburg pursued an effective strategic trade policy. Moreover the article investigates particular problems of the strategic trade policy.

Das Grundeinkommen - Potenziale und Grenzen eines Reformvorschlags
Ingmar Kumpmann
Wirtschaftsdienst,
No. 9,
2006
Abstract
Currently the idea of introducing a Basic Income is politically debated. A Basic Income is “an income paid by a political community to all its members, without means test or consideration” (Vanderborght/Van Parijs). It would replace the existing tax and welfare schemes which guarantee the subsistence levels for all individuals. The Basic Income would prevent poverty, simplify the tax and social security system and disburden labour from the costs of social security. It would put an end to the highly problematic governmental controls concerning the ability and willingness of the unemployed to work. The main challenges of the proposal are the difficulty of funding and the danger of reduced labour incentives, problems which limit the possibility for implementing the model.

Microeconometric Evaluation of Selected ESF-funded ALMP-Programmes
Eva Reinowski, Birgit Schultz
IWH Discussion Papers,
No. 17,
2006
Abstract
The study evaluates different ESF-funded labour market programmes by comparing the labour market status at different points in time after the treatment. In order to solve the selection problem we employ a standard matching algorithm with a multi-dimensional distance measure. The effects of the analyzed programmes (wage subsidies, start-up subsidies and qualification measures for recipients of social welfare) are very heterogeneous. It can be observed that the direct integration into the regular labour market provides an advantage for the supported individuals. Its lasting effects, however, strongly depend on the group of persons being supported, the type of treatment and the employers’ financial share.

Network investment and the threat of regulation: avoiding monopoly or infrastructure extension
Christian Growitsch, Niels Krap
Wirtschaft im Wandel,
No. 5,
2006
Abstract
In summer 2005, Deutsche Telekom announced its plans for the buildup of a new fiber glass network. At the same time, it formulated the condition that this network was not to be regulated concerning pricing or use by other providers (network access). In order to make this investment possible, in its coalition treaty the big coalition agreed to exclude the new network from the ex-ante regulation and to include this freedom from regulation in the telecommunication law. The question is now how investments can be facilitated and, at the same time, welfare losses through monopoly gains can be avoided. Applying game theory, it can be shown that a regulation authority like the ‘Bundesnetzagentur’, which is responsible for German telecommunication sector, should signal an increasing tolerance for deviations from its calculated and determined regulatory price in the face of increasing uncertainty concerning expected cost and returns. Thus, the threat of regulation alone leads to tolerable prices, without the actual regulation taking place. In the future, the ‘Bundesnetzagentur’ should reduce information asymmetries and the optimal level of tolerance in order to achieve a more precise intervention price and a more effective threat of regulation. The effectiveness of such a threat decreases if the legislation prevents the regulation authority from using this instrument by law. Against this background, the recent Federal Government resolution from March 17th 2006 noveling the telecommunication law heads for the economically right direction but it has to prove its incentive compatibility in the daily legal practice.

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.
