Abstract
In recent times the strategies of monetary policy, in particular that of the ECB, have been in the limelight of both scientific and public attention. After introducing into conceptual basics of monetary policy strategies, we compare inflation targeting and monetary targeting as the two prevalent strategies. The criteria established for this comparison are the way how the transmission of monetary policy is modeled, the role of expectations, the meaning of a nominal anchor as well as transparency and accountability. We conclude with a critical appraisal of the current ECB strategy.

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.

Außenhandel als Wachstumsmotor für Ostdeutschland
Götz Zeddies, Renate Ohr
Wirtschaftsdienst,
No. 9,
2007
Abstract
Whereas in the first years after reunification, GDP growth in Eastern Germany was considerably higher than in the Western part of the country, the catching-up of the newly formed German states slowed down since the end of the 1990s. But this was primarily caused by the development of domestic demand, whilst exports grew considerably. By means of an empirical model, the article reveals future export potentials of the New Laender and arrives at the conclusion that international trade might continue to stimulate GDP growth in Eastern Germany.

Slippery Slopes of Stress: Ordered Failure Events in German Banking
Thomas Kick, Michael Koetter
Journal of Financial Stability,
No. 2,
2007
Abstract
Outright bank failures without prior indication of financial instability are very rare. In fact, banks can be regarded as troubled to varying degrees before outright closure. But failure studies usually neglect the ordinal nature of bank distress. We distinguish four different kinds of increasingly severe events on the basis of the distress database of the Deutsche Bundesbank. Only the worst distress event entails a bank to exit the market. Since the four categories of hazard functions are not proportional, we specify a generalized ordered logit model to estimate respective probabilities of distress simultaneously. We find that the likelihood of ordered distress events changes differently in response to given changes in the financial profiles of banks. Consequently, bank failure studies should account more explicitly for the different shades of distress. This allows an assessment of the relative importance of financial profile components for different degrees of bank distress.

Systematic Mispricing in European Equity Prices?
Marian Berneburg
IWH Discussion Papers,
No. 6,
2007
Abstract
One empirical argument that has been around for some time and that clearly contra- dicts equity market efficiency is that market prices seem too volatile to be optimal estimates of the present value of future discounted cash flows. Based on this, it is deduced that systematic pricing errors occur in equity markets which hence can not be efficient in the Effcient Market Hypothesis sense. The paper tries to show that this so-called excess volatility is to a large extend the result of the underlying assumptions, which are being employed to estimate the present value of cash flows. Using monthly data for three investment style indices from an integrated European Equity market, all usual assumptions are dropped. This is achieved by employing the Gordon Growth Model and using an estimation process for the dividend growth rate that was suggested by Barsky and De Long. In extension to Barsky and De Long, the discount rate is not assumed at some arbitrary level, but it is estimated from the data. In this manner, the empirical results do not rely on the prerequisites of sta- tionary dividends, constant dividend growth rates as well as non-variable discount rates. It is shown that indeed volatility declines considerably, but is not eliminated. Furthermore, it can be seen that the resulting discount factors for the three in- vestment style indices can not be considered equal, which, on a risk-adjusted basis, indicates performance differences in the investment strategies and hence stands in contradiction to an efficient market. Finally, the estimated discount rates under- went a plausibility check, by comparing their general movement to a market based interest rate. Besides the most recent data, the estimated discount rates match the movements of market interest rates fairly well.

Schätzunsicherheit oder Korrelation, Welche Risikokomponente sollten Unternehmen bei der Bewertung von Kreditportfoliorisiken wann berücksichtigen?
Henry Dannenberg
IWH Discussion Papers,
No. 5,
2007
Abstract
The use of probability of default estimates to assess the risks of a credit portfolio should not ignore estimation uncertainty. The latter can be quantified by confidence intervals. But assumptions about dependencies of these intervals are inconsistent with assumptions of conventional credit portfolio models. Based on simulation studies this paper shows, that a model which include estimation uncertainty but ignore default correlation might estimate the real credit risk more correctly than a model that implicates default correlation but ignore estimation uncertainty. The latter is a trait of conventional credit portfolio models. In this paper quantifying of estimation uncertainty based on the idea of confidence intervals and the underlying probability distributions of these intervals.

Beschäftigung und Kapitalbildung in Deutschland
Hubert Gabrisch
Wirtschaft im Wandel,
No. 4,
2007
Abstract
Diese Studie untersucht die Bedeutung der Realkapitalbildung für die Beschäftigungsentwicklung in Deutschland. Augenscheinlich fällt ein Rückgang der Investitionsquote mit dem Rückgang des Arbeitsvolumens der Arbeitnehmer zusammen. Die Einkommens- und Kapazitätseffekte der Bruttoanlageinvestitionen werden mit einem Fehlerkorrekturmodell für den Zeitraum 1961 bis 2005 untersucht. Die Schätzergebnisse zeigen, daß die Hypothese von der Kapitalbildung als Determinante der Beschäftigungsentwicklung nicht abgelehnt werden kann. In Ergänzung wird getestet, ob sich eine Substitution von Arbeit und Kapital abzeichnet, wenn das Arbeitsangebot als zusätzliche Variable in das Modell eingeht. Ein über die Arbeitsnachfrage hinausgehendes Arbeitsangebot könnte zu einem (relativ) fallenden Reallohn und dadurch zu mehr Beschäftigung und weniger Investitionen führen. Der Test führt jedoch nicht zu einer Bestätigung dieser Substitutionshypothese. Als wirtschaftspolitische Konsequenz ergibt sich, die Bedeutung der Investitionen für die Beschäftigungsentwicklung höher als bisher zu bewerten und dabei auch jene Faktoren zu berücksichtigen, die nicht unmittelbar mit der Lohnbildung verbunden sind.

Considerable Export Potentials in Eastern Germany
Götz Zeddies
Wirtschaft im Wandel,
No. 2,
2007
Abstract
For a long time, the Federal Republic of Germany is one of the countries with the highest export performance in the world. But a closer examination of East- and West-Germany reveals substantial regional differences. The collabse of the markets in the eastern European countries, which were the main trading partners of GDR, after the breakdown of communism caused a sustainable decline of East-German exports. Nevertheless it was expected that the economic recovery in the former communist countries and the access to new export markets in the western world would cause an upward movement of East-German Trade. Although during the last years East-German exports grew faster than those of Western Germany, the east German share in Germanys total exports is still comparatively low. On the basis of a gravity-model of trade, bilateral export potencials are empirically analysed. This is done for the Federal Republic of Germany as a whole, and seperately forEast and West-Germany. Afterwards, the calculated export potencials are compared with actual exports. The results show that Germany as a whole exceeds its export potencial against the majority of its main trading partners. The differentiated analysis for East and West-Germany supports the hypothesis that Germanys high export performance stems from the western part of the country, whereas the eastern part exploits its export potencial with Germanys main trading partners only to the half. The unexploited export potencials as well as the higher concentration on the fast-growing central and eastern European markets imply considerable potencials for East-German exports to grow in the future.

Analysis of location of large-area shopping centres - A probalistic gravity model for the Halle-Leipzig area
Alexander Kubis, Maria Hartmann
Jahrbuch für Regionalwissenschaft,
No. 1,
2007
Abstract
A profund analysis of large-area shopping centres from the perspective of retail, but also of communes is of importance for the choice of site selection. In central Germany, the Halle–Leipzig area represents an example of strong competitiveness between the different participants in retail. The analysis described in this article is based on the MCI Model of Nakanishi and Cooper, which is used to investigate the regional influences of nine large shopping centres in the area of interest. The analysis demonstrates, that the studied shopping centres intensely affect the structure of retail in the region and exert a strong influence on the structural weakness of the surrounding cities due to their relative success in comparison to other retail locations city centres. An important volume of the turnover of the administrative districts flows to the analysed shopping centres. On the other hand, the article describes the influence of a systematic location decision on the reachable turnover potential of the modelized large-area shopping centres among each other. The shopping centres Saale Park (today Nova Eventis) near Leipzig and the Paunsdorf Center in Leipzig show the biggest influence on the competing centres.

Local Government Control and Efficiency of the Water Industry: An Empirical Analysis of Water Suppliers in East Germany
Peter Haug
IWH Discussion Papers,
No. 3,
2007
Abstract
The paper deals with the effects of local governments’ interference with business affairs of publicly owned utilities. A partial model is presented to illustrate the consequences of “democratic control” for the public managers’ effort and the efficiency of local public production. To check the theoretical results empirically, a two-stage data envelopment analysis (DEA) is carried out for a sample of East German water suppliers. The organisational form is used as a measure for the degree of municipal control. The results of the OLS- and Tobit regression indicate an efficiency-enhancing effect of organisational forms with less distinctive control options for local politicians.
