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.

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.

Peter Haug, Birger Nerré
Wirtschaft im Wandel,
No. 10,
2005
Abstract
At the 7th July 2005, the IWH under the auspices of the department of urban economics hosted a conference on the perspectives of municipal business activity in the range of water supply and disposal. Primary concern of the event was to determine the future role of municipalities. The colloquium was directed towards scientists, practitioners and politicians acting in the range of water management. The contributions addressed a wide range of topics, with the following emphases: benchmarking of municipal economic activity, empirical analyses on the efficiency and the propensity to invest, the problem of spatial disparities within the supply of infrastructure, reform suggestions for the framework of rules of the German water management. The lectures were followed by a panel discussion, attended by representatives from politics, organizations and science.

How do multinationals meet investment decisions: The case study of General Motors
Diemo Dietrich, Daniel Höwer
Wirtschaft im Wandel,
No. 10,
2005
Abstract
The recent events around Opel, the German subsidiary of General Motors, has attracted a great deal of attention, especially with respect to the influence of multinational corporations on the German economy. General Motors' announcement of an internal competition for production capacities in June 2004 has led some observers to the assessment that this would be a step towards more efficiency and profitability. But such internal competition for ressources may be hampered and end up in inefficiency. This is because informational frictions and enforcement problems within a corporation restrict the headquarters ability and willingness to allocate ressources efficiently. Against this background, we discuss possible problems associated with the internal capital allocation within multinational corporations and show their relevance in the case of General Motors.

Germany: Cyclical Improvement not Until the End of the Year
Wirtschaft im Wandel,
No. 12,
2001
Abstract
During the second quarter of 2001 German overall production stagnated. Weak global development muddied the economic prospects of firms and prevented them from rising their output and their investment activities. In 2001 gross national product will only increase by 1%; the number of unemployed will be higher than expected. Nevertheless, we advise against an increase in public expenditure that aims at stimulating the economy. Anyhow, growing public deficits, caused by cyclical movements, should be accepted. In order to increase employment labour market reforms become more urgent.
In East Germany, currently even a decline in gross national product cannot be excluded. After the first period of restructuring, which has been accompanied by structural problems, cyclical movements become more important. In addition, economic stagnation burdens labour markets. Nonetheless trying to stimulate the East German economy by government spending programmes does not seem to be a viable strategy. From the cyclical point of view they are not very efficient and concerning structural problems they are no solution.

Korean unification and banking system - An analysis in view of German experiences and Korean differences
Ralf Müller
IWH Discussion Papers,
No. 139,
2001
Abstract
One of the reforms that have to be launched in a future unification process in Korea, which seems possible after the political negotiations last year, is the transformation of the North Korean banking system. The question arises whether Korea could profit from the German experience where banking transformation was one of the rather few success stories in unification. In 1990 the East German banking transformation was achieved relatively fast and uncomplicated due to considerable direct investments of the West German banks compounded with state guarantees for bad loans resulting from the credit business with existing GDR-corporations. Unfortunately, South Korea currently lacks some major prerequesites that contributed to the German banking unification, among them – and probably the most important one – is the lack of a sound and efficient banking
system that could become active in the North. Consequently, depending on the circumstances of a future Korean unification either a more gradual process is recommended or, if inner-Korean migration requires a more dynamic transition, considerable investment by foreign banks and assistance from international organisations is recommended.
