Abstract
The steep increase of oil prices, general threats rooting from Iran’s nuclear program, and doubts about the future policy of important central banks recently caused more uncertainties of investors on international financial markets. This explains the higher volatility and the fall of indices on stock markets including those of some Central and East European countries. International investors could respond with adjustments of their portfolio and trigger off a financial crisis. On this background, the article studies the potential for a financial crises in the region mentioned. The analytical tool is the IWH signals approach. The study concludes that the risk of the outbreak of a financial crisis within the next 18 months is rather unrealistic in most countries. A stable economic policy, high real growth rates, a financial system already robust compared to earlier times of transition, and appropriate exchange rate arrangements protect the countries against speculative attacks and portfolio adjustments. When the composite indicator shows deterioration like in the Baltic countries, it turned out to be negligible. For the Slovak Republic and Slovenia, the composite indicator even improved. A closer look to individual indicators reveals still some problems in the banking sectors of the Czech Republic, Poland, and Hungary, however, without out major impact on the composite indicator.
This general assessment does not apply to Romania, and, in particular, to Turkey. The composite indicator signals a significant increase of the risk potential for the next 18 months in both countries. There is a considerable need for sound policy action.

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.

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.

Asset Tangibility and Capital Allocation within Multinational Corporations
Diemo Dietrich
IWH Discussion Papers,
No. 4,
2006
Abstract
We investigate capital allocation across a firm's divisions that differ with respect to the degree of asset tangibility. We adopt an incomplete contracting approach where the outcome of potential debt renegotiations depends on the liquidation value of assets. However, with diversity in terms of asset tangibility, liquidation proceeds depend on how funds have been allocated across divisions. As diversity can be traced back to institutional differences between countries, we provide a rationale for multidivisional decision- making in an international context. A main finding is that multinationals may be bound to go to certain countries when financiers cannot control the capital allocation.

Equity and Bond Market Signals as Leading Indicators of Bank Fragility
Reint E. Gropp, Jukka M. Vesala, Giuseppe Vulpes
Journal of Money, Credit and Banking,
No. 2,
2006
Abstract
We analyse the ability of the distance to default and subordinated bond spreads to signal bank fragility in a sample of EU banks. We find leading properties for both indicators. The distance to default exhibits lead times of 6-18 months. Spreads have signal value close to problems only. We also find that implicit safety nets weaken the predictive power of spreads. Further, the results suggest complementarity between both indicators. We also examine the interaction of the indicators with other information and find that their additional information content may be small but not insignificant. The results suggest that market indicators reduce type II errors relative to predictions based on accounting information only.

The Economics of Restructuring the German Electricity Sector
Christian Growitsch, Felix Müsgens
Zeitschrift für Energiewirtschaft,
No. 3,
2005
Abstract
The debate about the development of German electricity prices after the liberalization of energy markets in 1998 raises the question of failures in market restructuring. However, a general statement would be misleading for two main reasons. Firstly, the price development, analyzed for the exemplary case of household prices, shows significant differences among the stages of the value chain. Secondly, the underlying cost structure might have changed from 1998 to 2004. While such effects can be expected to level out over time, they can distort the comparison of a small period of observation. For these reasons, we analyzed the different price components at a detailed level, finding a considerable price reduction of about 32% in generation and a much lower reduction of 13% in transmission and distribution tariffs. These decreases have been mostly compensated by a significant increase in taxes and subsidies (+56%).

Panel Seasonal Unit Root Test: Further Simulation Results and An Application to Unemployment Data
Christian Dreger, Hans-Eggert Reimers
AStA - Advances in Statistical Analysis,
No. 3,
2005
Abstract
In this paper the seasonal unit root test of Hylleberg et al. (1990) is generalized to cover a heterogenous panel. The procedure follows the work of Im, Pesaran and Shin (2002). Test statistics are proposed and critical values are obtained by simulations. Moreover, the properties of the tests are analyzed for different deterministic and dynamic specifications. Evidence is presented that for a small time dimension the power is slow even for increasing cross section dimension. Therefore, it seems necessary to have a higher time dimension than cross section dimension. The new test is applied for unemployment behaviour in industrialized countries. In some cases seasonal unit roots are detected. However, the null hypotheses of panel seasonal unit roots are rejected. The null hypothesis of a unit root at the zero frequency is not rejected, thereby supporting the presence of hysteresis effects.

An analysis of household electricity price developments in Germany since liberalization
Christian Growitsch, Felix Müsgens
External Publications,
2005
Abstract
Despite the liberalization of energy markets in 1998, household electricity prices in 2004 are nearly the same as 1998, indicating a failure of market restructuring. However, such a general consideration is misleading for two main reasons. Firstly, the price development shows significant differences among the stages of the value chain. Secondly, the underlying cost structure might have changed from 1998 to 2004. While such effects can be expected to level out over time, they can distort the comparison of a small period of observation. For these reasons, we analyzed the different price components at a detailed level, finding a considerable price reduction of about 32% in generation and a much lower reduction of 13% in transmission and distribution tariffs. These decreases have been mostly compensated by a significant increase in taxes and subsidies (+56%).

Property networks of corporations as cause of abusive behaviour – A stock market analysis based on institutional economics
Makram El-Shagi
Applied Financial Economics Letters,
No. 5,
2005
Abstract
The present study deals with the fact that it seems as if executive boards have developed a self-service-mentality concerning the corporations they are meant to manage. The surprise about this is not the attempt of exploitation (rather the opposite would be surprising from an economic point of view) but the apparent absence of sanctions imposed by the owners. This study shows that this behaviour of corporations’ owners is at least to a main part due to the fact, that the reciprocal property of corporations prevents the exercise of certain property rights by the ‘true’ holders.

Deposit Insurance, Moral Hazard and Market Monitoring
Reint E. Gropp, Jukka M. Vesala
Review of Finance,
No. 4,
2004
Abstract
The paper analyses the relationship between deposit insurance, debt-holder monitoring, and risk taking. In a stylised banking model we show that deposit insurance may reduce moral hazard, if deposit insurance credibly leaves out non-deposit creditors. Testing the model using EU bank level data yields evidence consistent with the model, suggesting that explicit deposit insurance may serve as a commitment device to limit the safety net and permit monitoring by uninsured subordinated debt holders. We further find that credible limits to the safety net reduce risk taking of smaller banks with low charter values and sizeable subordinated debt shares only. However, we also find that the introduction of explicit deposit insurance tends to increase the share of insured deposits in banks' liabilities.
