Energy Efficiency of the Housing Stock: Are potential savings overrated?

No. 9,

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.

Arbeitskosteneffekte des Vorleistungsbezugs der Industrie an Dienstleistungen in Deutschland im Vergleich mit Frankreich und den Niederlanden – Eine Untersuchung mit der Input-Output-Methode. Gutachten im Auftrag des Instituts für Makroökonomie und Konjunkturforschung (IMK)

Abstract
As part of the outsourcing, industrial enterprises receive services in the production of their products which they used to provide on their own. As a result of the wage differentials between industry and service sector there is a shift in the burden labour costs have on industrial products. The study addresses the question of how significant this effect is. For this purpose the open static input-output model is used to analyse the degree of integration of the industry with its suppliers, the employment intensity of production and the labour cost differentials between the areas of production in Germany and in comparison with France and the Netherlands. The result of the labour cost analysis of industrial production shows - from a macroeconomic point of view - that the industry products have a smaller burden due to labour costs in Germany, France and the Netherlands, than the sectoral levels in the industry indicate. The difference in Germany is quantitative particularly strong pronounced. This saving in wage costs has increased somewhat after 2000. Crucial is that this discharge effect is achieved on the immediate wholesale inputs, that means in the first integration stage of industrial production.

Stages of the 2007/2008 Global Financial Crisis: Is there a Wandering Asset-Price Bubble?
Lucjan T. Orlowski
One-off Publications,
No. 3,
2008
Abstract
This study argues that the severity of the current global financial crisis is strongly influenced by changeable allocations of the global savings. This process is named a “wandering asset bubble”. Since its original outbreak induced by the demise of the subprime mortgage market and the mortgage-backed securities in the U.S., this crisis has reverberated across other credit areas, structured financial products and global financial institutions. Four distinctive stages of the crisis are identified: the meltdown of the subprime mortgage market, spillovers into broader credit market, the liquidity crisis epitomized by the fallout of Bear Sterns with some contagion effects on other financial institutions, and the commodity price bubble. Monetary policy responses aimed at stabilizing financial markets are proposed.

Change in East German Firm Level Export Determinants
Birgit Schultz
Wirtschaft im Wandel,
No. 3,
2010
Abstract
Exports have a ‘motor of growth’ status for the German economy. They both save and increase employment and provide wealth. However, only a minority of East German manufacturing and construction firms realize sales in foreign countries. The paper analyses for two points in time the influences of firm level export factors on the level of export activities of East German firms, and how the strength of the influence has changed over time. We found export sales especially in firms who are integrated in international corporate groups and are highly specialized. Economies of scale (firm size) increase the export share. Additionally, export sales also depend on wages. These findings are in line with current analysis in the field of international trade. While the above factors are found to be stable over time some others have changed in importance. In 2000 the industrial sector and the unit labor costs were important factors in determining export activities. In 2008 these factors have lost importance. Instead, human capital and investments have achieved significance.

Municipal Enterprises as Shadow Budgets – How do they Affect the Actual Budgetary Situation of Germany´s Local Governments?
Peter Haug
Wirtschaft im Wandel,
No. 5,
2009
Abstract
Outsourcing of municipal tasks from the core budget to municipal enterprises tends to distort the perception of the actual financial position, net assets and results of operations of the German local governments. Excess supply or -demand of/for local public services might be possible consequences of this development. Hence, this article attempts to develop a more comprehensive picture of the municipal budgetary position by a simultaneous analysis of selected indicators. Furthermore, the methodological problems of the calculations are illustrated.
If these shadow budgets are taken into account, the total per capita revenues, -investments and -debts will increase by approximately one third to 50%. However, the share of the municipal employees belonging to the core administration in the total number of municipal employees is 75%. Although only about 22% of the expenditures for certain voluntary municipal tasks have been outsourced, there seems to be an upward trend.
The study also indicates that there are significant differences between Eastern and Western German cities. These include the higher revenues from municipal enterprises, the higher debts per capita and the higher expenditures on culture, sports, leisure services or the promotion of science in Eastern Germany.
The results should be interpreted carefully due to some shortcomings of the official statistics. For example, internal cash flows cannot be totally eliminated. Moreover, indirect municipal majority holdings as well as the municipal savings banks are not included in the results.
All in all, it remains to be seen whether the initiated reforms concerning the introduction of double-entry accounting into the local government budgeting system will help to achieve the ideal goal of a meaningful “consolidated financial statement” for the “city company”.

The Transition to Post-industrial BMI Values among US Children

American Journal of Human Biology,

Abstract
The trend in the BMI values of US children has not been estimated very convincingly because of the absence of longitudinal data. Our objective is to estimate time series of BMI values by birth cohorts instead of measurement years. We use five regression models to estimate the BMI trends of non-Hispanic US-born black and white children and adolescents ages 2-19 between 1941 and 2004. The increase in BMIZ values during the period considered was 1.3 (95% CI: 1.16; 1.44) among black girls, 0.8 for black boys, 0.7 for white boys, and 0.6 for white girls. This translates into an increase in BMI values of some 5.6, 3.3, 2.4, and 1.5 units, respectively. While the increase in BMI values started among the birth cohorts of the 1940s among black girls, the rate of increase tended to accelerate among all four ethnic/gender groups born in the mid-1950s to early-1960s. Some regional evidence leads to the conjecture that the spread of automobiles and radios affected the BMI values of boys already in the interwar period. We suppose that the changes in lifestyle associated with the labor saving technological developments of the 20th century are associated with the weight gains observed. The increased popularity of television viewing was most prominently associated with the contemporaneous acceleration in BMI gain. Am. J. Hum. Biol., 2009. © 2008 Wiley-Liss, Inc.

Yes to Investments by Public Authorities for the Future! But Business Cycle will no Longer be Saved by it!

Wirtschaft im Wandel,
No. 3,
2009
Abstract
In order to mitigate the effects of the deep economic recession, the German federal government has adopted two economic stimulus packages to be applied in the period from 2009 to 2010. According to our estimations, these programs include investments amounting to 25.3 billion Euros mainly in infrastructure and education. We investigate the total effects of these investments on production and employment using a static input-output model. We find that the gross domestic product will increase by at most one percentage point, namely 0.4 points in 2009 and 0.7 points in 2010. This implies that approximately 400 000 jobs will be safeguarded. About one quarter of the effects will concern construction and business services respectively. For several reasons, our calculations constitute the upper bound to the expected effects. The increasing demand in construction could lead to significantly increasing prices. In light of the expected decline in production, the economic effects of the programs may appear to be low. Obviously, the strong decrease in external demand and its impact on the economy cannot be effectively combated by instruments of national economic policies.
