Abstract
Ein zentrales Element der europäischen Klimaschutzpolitik ist die Reduktion des Energieverbrauchs privater Haushalte. Im Fokus stehen dabei Wohnimmobilien, insbesondere im Mehrfamilienhausbestand. Die Energieeinsparverordnung
(EnEV 2009) fordert deshalb eine deutliche Reduktion des Energiebedarfs bei Sanierungen bzw. beim Neubau von Wohnimmobilien. Allerdings sind diese Vorgaben weitgehend undifferenziert, was Alter und Art einer Immobilie sowie die
Marktbedingungen betrifft, unter denen errichtet oder saniert wird. Der vorliegende Artikel zeigt auf Grundlage eines umfangreichen Datensatzes des Energiedienstleisters ista Deutschland GmbH, dass die Energiekennwerte von Mehrfamilienhäusern abhängig vom Jahr ihrer Errichtung sowohl im sanierten
als auch im unsanierten Zustand deutlich variieren. Die Daten zeigen zudem, dass die allgemein angenommenen Einsparpotenziale, die sich vor allem am technisch Machbaren orientieren, die Realität erheblich überschätzen. So sind die tatsächlichen Verbräuche in unsanierten Immobilien und die unter Marktbedingungen realisierten Energieeinsparungen nach einer Sanierung teilweise
deutlich geringer als bisher angenommen. Eine bautechnische und architektonische Betrachtung legt die Vermutung nahe, dass unterschiedliche
Sanierungskostenverläufe und die Bestandseigenschaften des Altbaus zu den beobachtbaren Differenzen beitragen. Im Ergebnis sprechen die hier präsentierten Zahlen für eine differenziertere Strategie, die sowohl die Belange der Wirtschaftlichkeit von Sanierungen, als auch die Belange des Klimaschutzes und Städtebaus berücksichtigt. Konkret bedeutet dies, dass sich die spezifischen
Eigenschaften von Immobilien auch in den rechtlichen Vorgaben und der Förderpolitik niederschlagen sollten, um Investitionsanreize auch tatsächlich
zu setzen.

A Cost Efficient International Lender of Last Resort
Tobias Knedlik
International Research Journal of Finance and Economics,
2010
Abstract
The current reform of the International Monetary Fund’s (IMF) lending instruments has transformed the Fund towards an international lender of last resort (ILOLR). Current research discusses various general frameworks for installing an ILOLR. However, it remains unclear how the ILOLR should actually operate. This paper discusses six different options for the construction of an ILOLR that supports central banks during currency crises. The paper concludes that the most cost efficient version of the ILOLR would be direct intervention by the IMF using IMF resources, with the option of using additional reserves from central banks. The paper considers measures of cost efficiency, such as cost of borrowing, intervention, and sterilization and moral hazard problems.

How Does Industry Specialization Affect the Efficiency of Regional Innovation Systems?
Michael Fritsch, Viktor Slavtchev
Annals of Regional Science,
No. 1,
2010
Abstract
This study analyzes the relationship between the specialization of a region in certain industries and the efficiency of the region in generating new knowledge. The efficiency measure is constructed by relating regional R&D input and output. An inversely u-shaped relationship is found between regional specialization and R&D efficiency, indicating the presence of externalities of both Marshall and Jacobs’ type. Further factors influencing efficiency are externalities resulting from high R&D intensity of the local private sector as well as knowledge from local public research institutions. The impact of both the specialization and the additional factors is, however, different for regions at different efficiency levels.

FDI and the National Innovation System - Evidence from Central and Eastern Europe

2010
Abstract
The paper investigates strategic motives, technological activities and determinants of foreign investment enterprises’ embeddedness in post-transition economies (Eastern Germany and selected Central East European countries). The empirical study makes use of the IWH FDI micro database. Results of the descriptive analysis of investment motives show that market access dominates over efficiency seeking and other motives. The majority of investors are technologically active in the region as a whole, but countries differ in terms of performance. The probit model estimations show that firm specific characteristics, among them innovativeness and autonomy from parent company, are important determinants of foreign investment enterprises’ embeddedness.

2010
Abstract
This paper concentrates on various factors preventing the establishment of an efficient regional innovation system in East Germany. For this purpose in the third section the strengths and weaknesses of the all German innovation system are elaborated by means of patent statistics. The fourth section describes the evolution of the East German innovation system after 1990, lists the most important supportive political measures, and discusses several reasons for deficits in innovative performance. The fifth section concludes and presents suggestions for political intervention.

Challenges for Future Regional Policy in East Germany. Does East Germany really show Characteristics of Mezzogiorno?

Abstract
Despite extensive government support the gap between East and West Germany has still not been successfully closed nearly 20 years post German unification. Hence, some economists tend to compare East Germany with Mezzogiorno – underdeveloped Southern Italy. East Germany is still subject to sever structural problems in comparison to West Germany: lower per capita income, lower productivity, higher unemployment rates, fewer firm headquarters and fewer innovation activities. There are East German regions with less than desirable rates of development. Nevertheless, the new federal states have shown some evidence of a convergence process. Some regions have developed very positively – they have improved their competitiveness and employment levels. As such, the comparison of East Germany with Mezzogiorno does not seem applicable today.
According to Neoclassical Growth Theory, regional policy is targeted enhancing investment (hereafter the notion ‘investment policy’ is used). has been the most important instrument in forcing the ‘reconstruction of the East’. Overall, the investment policy is seen as having been successful. It is not, however, the only factor influencing regional development – political policy makers noted in the mid 1990s that research and development (R&D) activities and regional concentrated production networks, amongst other factors, may also play a part. The investment policy instrument has therefore been adjusted. Nevertheless, it cannot be excluded that investment policy may fail in particular cases because it contains potentially conflicting targets. A ‘better road’ for future regional policy may lie in the support of regional production and innovation networks – the so-called industrial clusters. These clusters would need to be exactingly identified however to ensure effective and efficient cluster policies.

Knowledge Spill-overs for Knowledge-based Development: Progression in Theory and Obstacles for Empirical Research
Peter Franz
International Journal of Knowledge-Based Development,
2010
Abstract
As scientists and policymakers tend to interpret changes in the economy as a trend towards an increasingly knowledge-based economy, their recommendations and strategies for regional economic development frequently contain elements how to intensify the knowledge flows in the region concerned. Knowledge flows come into existence from intentional action, but also in an unintended way as externalities or knowledge spillovers. This paper reviews the ways regional and urban economics has dealt with the concept of knowledge spillovers. Knowledge spillovers are defined within a conceptual framework that points out different uses of knowledge in economics. The concept’s operationalisations in diverse empirical studies are systematised and discussed. After a critical review of the current state of research, policy strategies aiming to intensify knowledge spillovers are classified. The paper concludes with an outlook on promising new approaches to research knowledge spillovers and on the elaboration of more efficient policy strategies.

Technology Clubs, R&D and Growth Patterns: Evidence from EU Manufacturing
Claire Economidou, J. W. B. Bos, Michael Koetter
European Economic Review,
No. 1,
2010
Abstract
This paper investigates the forces driving output change in a panel of EU manufacturing industries. A flexible modeling strategy is adopted that accounts for: (i) inefficient use of resources and (ii) differences in the production technology across industries. With our model we are able to identify technical, efficiency, and input growth for endogenously determined technology clubs. Technology club membership is modeled as a function of R&D intensity. This framework allows us to explore the components of output growth in each club, technology spillovers and catch-up issues across industries and countries.

Do All Countries Grow Alike?
Claire Economidou, J. W. B. Bos, Michael Koetter, James W. Kolari
Journal of Development Economics,
No. 1,
2010
Abstract
This paper investigates the driving forces of output change in 77 countries during the period 1970–2000. A flexible modeling strategy is adopted that accounts for (i) the inefficient use of resources, and (ii) different production technologies across countries. The proposed model can identify technical, efficiency, and input change for each of three endogenously determined regimes. Membership in these regimes is estimated, rather than determined ex ante. This framework enables explorations into the determinants of output growth and convergence issues in each regime.
