Abstract
A decade after its introduction the European Monetary Union is no more undisputed. While a successful record regarding price stability cannot be doubted, the EMU still suffers from high unemployment – not only related to the Financial Crisis. In this contribution we want to cast light on the question how this might be related to a dismal mix of wage policy and monetary policy. Taking a consideration of the European Macroeconomic Dialogue as a starting point, we develop a game theoretic model which can explain different macroeconomic alternatives. As a result we present a reputation equilibrium which would make full employment and price stability compatible and does not rest on overriding the actors’ independence.

Central Banks, Trade Unions and Reputation – Is there Room for an Expansionist Manoeuvre in the European Union?
Toralf Pusch, A. Heise
Journal of Post Keynesian Economics,
2010
Abstract
It is now a few years since the introduction of the common currency, and Europe is still experiencing high unemployment. The conventional logic attributes this problem to flaws in the labour market. In this article we look at the changes that occur if labour unions and the Central Bank have different options to choose from in a climate of uncertainty. In a single-stage game the most probable outcome is a high unemployment rate. Results change dramatically if the game is repeated. However, this effect does not occur if the Central Bank puts a too high weight on price stability. Secondly, if the trade unions do not possess the capability for coordinating and moderating their wage claims, a full employment equilibrium is out of range.

Economic Effects of Investment Grants for Water and Sewerage Infrastructure – The Case of Saxony
Peter Haug
Wirtschaft im Wandel,
No. 11,
2010
Abstract
The article deals with the regional economic growth effects of the German “Joint Scheme” for the improvement of regional economic structures (“GA-Infra”). It focuses on water and sewerage projects located in the federal state of Saxony (Germany) during the funding period 2000-2007. Evaluating these projects is important for scientific as well as for economic policy reasons.
First of all, according to general economic theory, the potential direct and indirect supply-side effects of the water and sewerage infrastructure as well as the price effects caused by this infrastructure are relevant for location decisions only to certain branches of the manufacturing industry.
Subsidies for the development of the sewerage infrastructure have been granted mostly according to the growth target of regional policy, i.e. primarily to municipalities with above-average volumes of industry sewage. This finding could not be confirmed for water provision.
A regression analysis (estimating the labour demand of the local manufacturing industry) showed no empirical evidence for any relationship between the changes in labour demand and the amount of GA-Infra funded water and sewerage infrastructure investments. This might be a consequence of the already satisfactory development condition of the infrastructure in question at the beginning of the funding period (“ubiquitous infrastructure”).
According to a survey of local governments conducted by the IWH, these results might be explained by the fact that business customers did not benefit from price reductions despite the GA-Infra funding granted to their local water and sewage disposal providers. Even though there might be some intuitively plausible reasons (decreasing population, no connection fees) for these findings, no effect on firm location decisions can be expected under these circumstances.
All in all, we do not consider the further extension of these funding priorities to be necessary. Especially, the GA-Infra water/sewerage grants should neither be used to mitigate the cost effects of demographic changes or regulation nor to compensate for losses caused by the buyer power of large firms.

On the Look-out for a White Knight: Options-based Calculation of Probability and Expected Value of Increased Bids in Hostile Takeover Battles
Stefan Eichler, Dominik Maltritz
Applied Economics Letters,
No. 11,

Abstract
Takeover bids provide an option right to the target's shareholders; they guarantee the offered price but maintain the chance of higher offers. Using Option Pricing Theory (OPT) we estimate the probability and expected value of higher bids from target stock prices.

Das Energiekonzept für Deutschland – ein Kommentar
Wilfried Ehrenfeld
Wirtschaft im Wandel,
No. 10,
2010
Abstract
Am 28. September dieses Jahres hat das Bundeskabinett das Energiekonzept beschlossen. Inhalt dieses Konzeptes ist die Zukunft der Energieversorgung in Deutschland allgemein und die Zukunft der erneuerbaren Energien im Speziellen. Der Plan ist dabei in neun Handlungsfelder unterteilt. Diese reichen von der Rolle erneuerbarer Energien allgemein über Energieeffizienz, Mobilität, Energieversorgung im europäischen und internationalen Kontext bis hin zu energetischer Gebäudesanierung , Klimaschutz und zur Rolle der Kernkraft. So ist in diesem Konzept beispielsweise vorgesehen, die Treibhausgasemissionen bis 2020 um 40% und bis 2050 um mindestens 80% gegenüber 1990 zu reduzieren, was als ambitioniertes Ziel gewertet werden kann.

The Russian System of Cities from the Perspective of New Economic Geography
Albrecht Kauffmann
Potsdamer Schriften zur Raumwirtschaft, Bd. 2,
2010
Abstract
The rise in energy prices may result in long-lasting rise in costs of freight transports. Which effects do rising freight transport costs have for the development of urban systems? Such rise of transport costs in real terms has happened in Russia after price liberalisation in 1992. At the same time, the Russian official demographic statistics provides data that can be used to test hypotheses concerning the development of urban systems affected by rising transport costs. In the present study, these data are comprehensively evaluated. The theoretical background is provided by modelling of a linear shaped urban system in the framework of New Economic Geography. By means of this tool, analysis can be applied to spacious urban systems with large transport distances. For the first time, the underlying theoretical approach is explained in detail. The empirical results provide evidence for the outcomes of the theoretical model: In spacious countries or regions, respectively, whose urban systems are drawn-out on long lines, rising costs of freight transport are conducive to tendencies of concentration of population in large cities in the centre of the system, while peripheral regions are increasingly disconnected.

Currency Crisis Prediction Using ADR Market Data: An Options-based Approach
Stefan Eichler, Dominik Maltritz
International Journal of Forecasting,
No. 4,
2010
Abstract
During capital control episodes, large price deviations between American Depositary Receipts (ADR) and their underlying stocks signal that a currency crisis is about to occur. We interpret this price spread as the price of a call option. Using option pricing theory we derive detailed information about both the probability of a currency crisis and the expected magnitude of devaluation. Analyzing daily ADR market data preceding the Venezuelan crisis (1996), our approach predicts crisis probabilities of almost 100% and forecasts the exchange rate after floating quite accurately. During the Argentine crisis (2002), the estimated exchange rates are similar to the actual ones.

Investor Rationality and House Price Bubbles: The Case of Berlin and the German Reunification
Oliver Holtemöller, R. Schulz
German Economic Review,
2010
Abstract
We analyze the behavior of investors in the Berlin rental apartment house market over the years 1980–2004. Using constant-quality multipliers (price–rent ratios), we reject the hypothesis that multipliers in the market were set in a rational manner. Supported by narrative evidence, we conjecture that investors misjudged the economic effects of the German reunification. To examine this, we employ a stylized structural economic model and analyze the effects of shocks on rational multipliers. It seems that investors confused the reunification with a permanent supply side shock to the economy. By basing their investment decisions on this misjudgement, investors behaved irrationally, but in a very uncertain and unprecedented environment.

Energy Efficiency of the Housing Stock: Are potential savings overrated?
Claus Michelsen, S. Müller-Michelsen
Wirtschaft im Wandel,
No. 9,
2010
Abstract
A core element of the European Climate Protection Policy is the reduction of Energy usage in private households. Legal instruments focus particularly on private multifamily housing. When refurbishing or building a new home, the German regulation for energy saving in buildings and building systems, Energieeinsparverordnung (EnEV 2009), thereby formulates relatively strict standards on energy conservation. But these standards mainly address the technical potentials of energy efficiency gains instead of considering market conditions and different types of housing, especially their age. Theory suggests that legal settings therefore retain owners to refurbish their homes, when returns on investment are negative, especially in regions where market conditions do not allow for higher rents or the costs of refurbishment are too high.
The article presents evidence for these theoretical considerations: based on a large scale sample provided by the company ista Germany, it can be shown, that energy usage differs by the age of dwellings and by the standard of refurbishment. Data suggests that the assumed potentials of energy conservation, which are mainly motivated by technical considerations, are too high. The differences may be a result of different cost functions of refurbishment. Further evidence for this finding is provided by architectural considerations.
As a result, the article suggests to legally distinguishing between different types of housing and to consider market conditions, when providing public funding for energy efficiency. It is suggested to implement a two multidimensional strategy, considering climate protection, urban development issues and the rationality of real estate investors.

“Geschäftsmodell Deutschland“ und außenwirtschaftliche Ungleichgewichte in der EU
Renate Ohr, Götz Zeddies
List Forum für Wirtschafts- und Finanzpolitik,
2010
Abstract
During the last decades, current account imbalances increased all over the world. In this context, countries with current account surpluses, in the European Union especially Germany, are increasingly blamed for their modest wage policies, which are seen as the main reason for global imbalances. On the basis of a panel data model, the present paper indentifies the determinants of current account imbalances of EU Member States. As the results show, price competitiveness is, although significant, only one out of many explanatory variables. Instead, current account imbalances are substantially caused by divergent propensities to save. This does not only relate to public, but also to private savings. Accordingly, demands addressed to Germany and other countries for higher wage agreements alone would be unrewarding. Instead, domestic demand in surplus countries should be increased by other means. On the other hand, in countries with current account deficits, existing savings potentials should be adequately exploited.
