Longterm development of return on assets – an empirical panel data analysis
Olaf Neubert
Wirtschaft im Wandel,
No. 5,
2006
Abstract
One of the basic propositions of economic theory is the fact that competition does not allow permanent very high or very low returns. But how can the permanent surplus gain of a monopolist be distinguished from innovation gains? In which markets is a regulatory interference necessary? Contrary to the static analysis, the concept of dynamic competition explicitly considers the temporal development of return and gain. An entrepreneur can achieve an advantage over the competitors through new products or new production processes. Hence arising innovation gains function as incentives for imitators to join the development which in turn leads to a reduction of the surplus gains. Thus, these gains are not contradictory to an effective competition. On the basis of annual balance sheets of German firms, this article analyses the temporal development of returns on assets. It is to evaluate whether the adaptation process assumed by Schumpeter that matches very high and very low gains with a longterm level can be confirmed, and how fast this process works. The average industry returns of the manufacturing industry show a convergence to a longterm level. During this process, an average of 40% of the deviation from the longterm level are melted every year. However, the analysis of company returns shows longterm differences. The adaptation rate of companies, 50%, is significantly higher compared to the industry value. The analysis of the connection between the adaptation rate and the longterm return level of companies proves that companies which face above-average competition strength obtain a higher longterm return level than other companies. When firms operate within markets with high stress of competition they do not achieve below-average returns but rather significantly above-average returns in the long term.

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.

Angewandte Industrieökonomik: Theorien, Modelle, Anwendungen
Ulrich Blum, Simone Müller, Andreas Weiske
,
2006
Abstract
Modern entrepreneurship comprises a mix of bourgeois morale and the striving for adventure: Bourgeois morale implies efficiency, reputation, the rule of the law. And adventure implies new frontiers, the spirit of competition, innovation and a pioneer’s attitude – up to the destruction of competitors. The modern entrepreneur’s social position thus is a ambiguous; the entrepreneur needs a special attitude with respect to economic activity as discussed by Werner Sombard (1913) and Max Weber (1905); society has to accept the positive ethical quality of profit seeking in order to survive. The modern theory of the enterprise promoted by neoclassic theory does not include any of these elements of real entrepreneurship. Industrial organisation theory tries to structure models closer to reality, thus allowing empirical testing. In many aspects, it is based on neoclassic theory, but also accepts the concept of strategic behaviour which includes potential reactions of other market participants in ones own activities. Elements of evolutionary economics, risk theory and modern information theory thus become important. The overarching question of the entrepreneur, who strives for a higher than normal profit in the market becomes: under which conditions should I enter the market and under which conditions will potential entrants do the same? How should I set my prizes and what reactions must I expect? How can I signal friendly behaviour to competitors? How can I differentiate myself from them? What importance do innovations and advertising have? The book roles out these questions in three large chapters on technology and market structure, on prize setting and signalling, and on research, development and innovation. An introduction explains individual behavioural patterns within the societal context – often in a historical perspective. Three methodological chapters introduce the reader into strategic thinking as the core aspect of the industrial organisation theory, the “old industrial organisation theory” and the neoclassic basic models. Each chapter is extended by exercises and tips for solutions.

Die Bedeutung interner Kapitalmärkte für die Organisationsform von Unternehmen
Diemo Dietrich
WiSt - Wirtschaftswissenschaftliches Studium,
2006
Abstract
Contemporary financial economics has broken new grounds when considering that firms typically have not only a single investment opportunity available conducted by a single manager. A Firm has in fact several projects where headquarters delegates the undertaking to project managers. From this perspective, what conclusions can be drawn regarding the functioning of capital markets? What role do internal capital markets play? What consequences does it have for the borders of a firm?

The coalition treaty from a fiscal point of view
Kristina vanDeuverden
Wirtschaft im Wandel,
No. 12,
2005
Abstract
After weeks of negotiations the coalition finally agreed on the conditions for their political work. Not surprisingly, the coalition agreement is complex and intransparent – with a multitude of single measures far away from a precise definition. Quantifying the programme and estimating resulting cash flows is currently difficult; official calculations are – if at all – only partly available. Anyhow, the contract will form the basis for economic policy during the next four years; therefore its evaluation by now is indispensable. The thin red line of the agreement – not astonishingly when considering the precarious financial situation of the public sector – is consolidation. However, more than 80% of the consolidation volume results from the revenue side. Though one third of this is due to the cutback of tax exemptions, the lion’s share comes from raising tax rates, mainly the VAT standard rate. In contrast, cutting back public expenditure is minor and the agreement clearly comes short of the Koch/Steinbrück proposal; even new tax reliefs are created. The consolidation is almost completely borne by private households. Enterprises as a whole are barely hit. However, they have to wait until 2008 for a reform of company taxation – one of the most pressing problems in this legislative period. To reduce the companies tax burden until the reform starts the conditions for tax depreciation are temporarily relaxed. Anyway, from an international point of view the statutory tax rate is an important signal to enterprises deciding where to invest. Lowering effective tax rates by changing depreciation conditions is intransparent and, thus, will be less effective. Furthermore savings within the public sector are planned to accomplish consolidation; 10 billion Euro should result from efficiency gains and reduced expenditure. Consolidation measures mainly focus on the budget of the federal government. However, Länder and communities will participate in the additional tax revenues. In contrast, social securities will loose – and therefore also the share of employment that is subject to social insurance contribution. Particularly the unemployment insurance will be burdened by the decrease of its premium rate. Besides, the federal government will reduce its grants to the pension funds and most notably the health system. The contract is dominated by fiscal constraints. Cyclical requirements are considered only cursory and pressing structural reforms are put off. The reforms of company’s taxation, of fiscal federalism, of the health system as well as a proceeding reform of the labour market are only proposed. How and when measures in these fields are realised will determine whether fiscal policy can set a new course.

The (never) ending story of the truck toll system – a contract theory view
Niels Krap
Wirtschaft im Wandel,
No. 11,
2005
Abstract
After long-lasting negotiations, representatives of the Federal Government and the consortium Toll Collect signed a 17,000 pages contract on 20 September, 2002. It was fixed that Toll Collect had to develop and afterwards operate a system for the automatic collection of a satellite-supported distance-based truck toll until the end of August 2003. However, technical difficulties in the development of the new system led to delays to an unexpected extent. In this article, it is examined whether the results of the renegotiations that followed were consistent to the economics of contract theory. It can be shown that both contracting parties were bound to the contractual relation, so that the preliminary termination of the contract by the Federal Minister of Transport on 17 February, 2004 became void by an agreement only few days later. Additionally, it could be identified that the contract set correct incentives for both parties, Federal Government and Toll Collect, and covered the possibility of efficient renegotiation.

Sachsen-Anhalt als Wirtschaftsstandort: Wie erfolgreich sind das Land und seine Regionen?
Martin T. W. Rosenfeld
Geographische Rundschau,
2005
Abstract
The article examines the economic performance and the conditions for future economic development in the German Land of Saxony-Anhalt. After the integration of Saxony-Anhalt into the market economy since 1989, strong structural changes have taken place. Nevertheless, agriculture, coal mining and the chemical industry as some of the traditional sectors of the Land’s economy have remained their importance. The weak points of the economy are the low number of entrepreneurs and a low tendency for innovations in the private sector. The Magdeburg region and the Halle region have better conditions for (inter-) national competitiveness than the Altmark region and the Dessau region. But the potentials of the urban centers Magdeburg and Halle are - as compared to other East German cities - not very strong. For improving the eonomic conditions, new instruments for stimulating entrepreneurship and for strengthening the position of the two urban centers should be installed. In addition, innovation activities of private firms could be improved by new linkages between the private sector and Saxony-Anhalt’s public research units.

Economic Capability of East German Regions: Results of a Cluster Analysis
Franz Kronthaler
Regional Studies,
No. 6,
2005
Abstract
This paper analyses the economic capability of East German regions compared with West German regions. Based on new growth theory and new economic geography, and using relevant empirical literature, regions are clustered according to a set of growth factors. The clustering results find little evidence that the economic capability of East German regions is already comparable with West German regions. Economic disadvantages are particularly rooted in lower technical progress, a lack of entrepreneurship, lower business and industrial concentration, and a loss of human capital. However, there are a few East German regions with a high economic capability, but even those suffer from economic disadvantages such as lower technical progress, lower industrial activity and a poorer regional accessibility.
