The Quantity Theory Revisited: A New Structural Approach
Makram El-Shagi, Sebastian Giesen
Abstract
While the long run relation between money and inflation is well established, empirical evidence on the adjustment to the long run equilibrium is very heterogeneous. In this paper we show, that the development of US consumer price inflation between 1960Q1 and 2005Q4 is strongly driven by money overhang. To this end, we use a multivariate state space framework that substantially expands the traditional vector error correction approach. This approach allows us to estimate the persistent components of velocity and GDP. A sign restriction approach is subsequently used to identify the structural shocks to the signal equations of the state space model, that explain money growth, inflation and GDP growth. We also account for the possibility that measurement error exhibited by simple-sum monetary aggregates causes the consequences of monetary shocks to be improperly identified by using a Divisia monetary aggregate. Our findings suggest that when the money is measured using a reputable index number, the quantity theory holds for the United States.

The Term Structure of Banking Crisis Risk in the United States: A Market Data Based Compound Option Approach
Stefan Eichler, Alexander Karmann, Dominik Maltritz
Journal of Banking and Finance,
No. 4,
2011
Abstract
We use a compound option-based structural credit risk model to estimate banking crisis risk for the United States based on market data on bank stocks on a daily frequency. We contribute to the literature by providing separate information on short-term, long-term and total crisis risk instead of a single-maturity risk measure usually inferred by Merton-type models or barrier models. We estimate the model by applying the Duan (1994) maximum-likelihood approach. A strongly increasing total crisis risk estimated from early July 2007 onwards is driven mainly by short-term crisis risk. Banks that defaulted or were overtaken during the crisis have a considerably higher crisis risk (especially higher long-term risk) than banks that survived the crisis.

Exchange Rate Expectations and the Pricing of Chinese Cross-listed Stocks
Stefan Eichler
Journal of Banking and Finance,
No. 2,
2011
Abstract
I show that the price discounts of Chinese cross-listed stocks (American Depositary Receipts (ADRs) and H-shares) to their underlying A-shares indicate the expected yuan/US dollar exchange rate. The forecasting models reveal that ADR and H-share discounts predict exchange rate changes more accurately than the random walk and forward exchange rates, particularly at long forecast horizons. Using panel estimations, I find that ADR and H-share investors form their exchange rate expectations according to standard exchange rate theories such as the Harrod–Balassa–Samuelson effect, the risk of competitive devaluations, relative purchasing power parity, uncovered interest rate parity, and the risk of currency crisis.

Möglichkeiten für Vollbeschäftigungspolitik im Rahmen des Europäischen Makroökonomischen Dialogs
Toralf Pusch, A. Heise
K. Busch (Hrsg.), Wirtschaftliche und Soziale Integration in der Europäischen Union,
2010
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,
2010
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.

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.

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.

What are the Long-Term Benefits of the Economic Stimulus Package II for German Local Governments? – The Case of Saxony
Peter Haug
Wirtschaft im Wandel,
No. 4,
2010
Abstract
This article deals with the question whether the investments subsidized by the economic stimulus package II („Konjunkturpaket II“) do not only have short-term effects on demand but also long-term effects e.g. on local economic growth. As far as the short-term effects are concerned, the case of the German state of Saxony shows – with some delay – a rise in local government´s investments. Hence, the time-lag problem inherent in all governmental spending programmes seems to keep within reasonable limits. Up to now there have been no signs of inflationary price tendencies in the construction sector.
According to - for example - the „new“ economic growth theory, one ought to be sceptical about the long-term effects of the projects supported by the programme: Even for genuine public intermediate goods the withdrawal effects of financing have to be weighed against the positive effects on private enterprise sector productivity. Furthermore, the effects on factor prices caused by the investment grants might encourage the excess use of physical capital in public production.
This sceptical attitude of the theory is confirmed for Saxony by the fact that primarily public consumption goods (sports and leisure facilities) or educational facilities (kindergartens, primary schools), which are of no direct relevance to the local enterprises, are supported by the programme. Investments in vocational training, research and development play only a minor role at the local government level or are explicitly excluded from the programme.
Especially because of the incentives to misallocate public resources it is recommended to rely on unconditional grants in future support programmes. Then the local governments could use the grants for either „investments” in human capital (new [fixed-term contract] hires, qualification) or in physical capital, according to their needs.
