Abstract
Deutschlands Mehrfamilienhäuser verbrauchen immer weniger Energie. Dies ist das Ergebnis des ista-IWH-Energieeffizienzindex für die Abrechnungsperiode 2010. Gegenüber der Vorperiode ist der Energiebedarf für Raumwärme bundesweit um rund 2,3% zurückgegangen. Im Fünfjahresvergleich ist dies leicht unterdurchschnittlich: Im Mittel betrug der Rückgang rund 2,4% seit 2005. Dennoch ist der Energieverbrauch mit rund 131,1 Kilowattstunden je Quadratmeter Wohnfläche im Jahr nach wie vor deutlich von dem von der
Bundesregierung formulierten Ziel – einer Reduktion des Energieverbrauches von Immobilien um 80% bis 2050 – entfernt. Das räumliche Muster der durchschnittlichen Energiekennwerte verändert sich insgesamt nur sehr langsam. Tendenziell ist eine Angleichung zwischen den Neuen und den Alten Ländern zu beobachteten. Im Osten stagnieren die Energiekennwerte auf einem Niveau unterhalb des Bundesdurchschnitts, im Westen sinken sie in den meisten Regionen. Eine höhere Dynamik geht dabei insbesondere von den Regionen im Süden Deutschlands aus.

Africa and the Global Financial Crisis - Impact on Economic Reform Processes
R. Adelou Alabi, J. Alemazung, Achim Gutowski, Robert Kappel, Tobias Knedlik, O. Osnachi Uzor, Karl Wohlmuth, Hans H. Bass
African Development Perspectives Yearbook, Vol. 15,
2011
Abstract
In volume XV of the African Development Perspectives Yearbook, the Research Group on African Development Perspectives investigates the impact of the GFC on economic reform processes in Africa. The analysis is structured in such a way so as to reflect the opportunities and dangers of policy reversals in the face of the GFC. The impact of the crisis on different types and forms of governance in the region is considered. The first question is therefore which macro-economic policy instruments have to be applied in order to overcome the crisis and to continue with sustainable development. The second question is how the GFC has affected Africa's external economic relations and if the path of opening up to the world markets is continued. The third question raised is how the crisis has affected social cohesion, impacted on poverty alleviation strategies and the achievement of Millennium Development Goals (MDGs). All these questions are discussed in the various contributions which comprise general studies and country case studies. The authors also looked into the role of international financial institutions during and after the crisis. The volume XV of the African Development Perspectives Yearbook is structured into three Units. Unit 1 addresses general issues regarding the impact of the GFC on reform processes in Africa. Unit 2 presents case studies from countries and sub-regions. Unit 3 presents reviews and book notes of current literature focusing on issues of African development perspectives.

Preventing Innovative Cooperations: The Legal Exemptions Unintended Side Effect
Christian Growitsch, Nicole Nulsch, Margarethe Rammerstorfer
European Journal of Law and Economics,
Nr. 1,
2012
Abstract
In 2004, European competition law had been considerable changed by the introduction of the new Council Regulation No. 1/2003. One of the major renewals was the replacement of the centralized notification system for inter-company cooperations in favor of a so-called legal exemption system. We analyze the implications of this reform and its arising uncertainty on the agreements firms implement, especially on innovative agreements like vertical R&D agreements. By means of a decision theoretic approach, we show that the law’s intention to reduce the incentive to establish illegal cartels will be reached but innovating cooperations might be prevented. To avoid this unintended side effect, fines but not the monitoring activities should be increased.

Business Volatility, Job Destruction, and Unemployment
Steven J. Davis, R. Jason Faberman, John Haltiwanger, Ron S. Jarmin, Javier Miranda
American Economic Journal: Macroeconomics,
Nr. 2,
2010
Abstract
Unemployment inflows fell from 4 percent of employment per month in the early 1980s to 2 percent by the mid 1990s. Using low frequency movements in industry-level data, we estimate that a 1 percentage point drop in the quarterly job destruction rate lowers the monthly unemployment inflow rate by 0.28 points. By our estimates, declines in job destruction intensity account for 28 (55) percent of the fall in unemployment inflows from 1982 (1990) to 2005. Slower job destruction accounts for similar fractions of long-term declines in the rate of unemployment.

FDI versus exports: Evidence from German banks
Claudia M. Buch, A. Lipponer
Journal of Banking and Finance,
Nr. 3,
2007
Abstract
We use a new bank-level dataset to study the FDI-versus-exports decision for German banks. We extend the literature on multinational firms in two directions. First, we simultaneously study FDI and the export of cross-border financial services. Second, we test recent theories on multinational firms which show the importance of firm heterogeneity [Helpman, E., Melitz, M.J., Yeaple, S.R., 2004. Export versus FDI. American Economic Review 94 (1), 300–316]. Our results show that FDI and cross-border services are complements rather than substitutes. Heterogeneity of banks has a significant impact on the internationalization decision. More profitable and larger banks are more likely to expand internationally than smaller banks. They have more extensive foreign activities, and they are more likely to engage in FDI in addition to cross-border financial services.

Explaining Regional Disparities in Housing Prices across German Districts
Lars Brausewetter, Stephan L. Thomsen, Johannes Trunzer
IZA Institute of Labor Economics,
March
2022
Abstract
Over the last decade, German housing prices have increased unprecedentedly. Drawing on quality-adjusted housing price data at the district level, we document large and increasing regional disparities: growth rates were higher in 1) the largest seven cities, 2) districts located in the south, and 3) districts with higher initial price levels. Indications of price bubbles are concentrated in the largest cities and in the purchasing market. Prices seem to be driven by the demand side: increasing population density, higher shares of academically educated employees and increasing purchasing power explain our findings, while supply remained relatively constrained in the short term.
