Forecasting Currency Crises: Which Methods signaled the South African Crisis of June 2006?
Tobias Knedlik, Rolf Scheufele
South African Journal of Economics,
2008
Abstract
In this paper we test the ability of three of the most popular methods to forecast South African currency crises with a special emphasis on their out-of-sample performance. We choose the latest crisis of June 2006 to conduct an out-of-sample experiment. The results show that the signals approach was not able to forecast the out-of-sample crisis correctly; the probit approach was able
to predict the crisis but only with models, that were based on raw data. The Markov-regime- switching approach predicts the out-of-sample crisis well. However, the results are not straightforward. In-sample, the probit models performed remarkably well and were also able to detect, at least to some extent, out-of-sample currency crises before their occurrence. The recommendation is to not restrict the forecasting to only one approach.

Rents and Quality of Life in Eastern Germany
Dominik Weiß
IWH Discussion Papers,
No. 12,
2008
Abstract
The rent levels between East- and Westgermany differ less than one Euro on average. This difference seems very slow regarding the persistant economic disparities and high vacancy rates in East-Germany.
Based on the assumtion, that income and life quality aspects have an impact on the local rent level a set of variables is regressed on the rent of several housing quality segments in a cross-section analysis at the community-level. The regression contains demographic, economic and housing-market-related variables and a dummy variable for east germany. It incorporates hypotheses about a special supplier structure and several market interventions that are related to the transformation process from socialistic into market economic structures after the reunification in the 1990s.
The results show a significant positive coeficiant for the east german dummy in two segments of the housing stock. Further Research about the reasons for the extra charge are important, because theese findings may be responsible for the continous out migration from East Germany.

German Economy on the Brink of Recession
Wirtschaft im Wandel,
2. Sonderausgabe
2008
Abstract
In autumn 2008, the word economy is in a downswing, caused by the commodity and energy price hike of the first half of the year, housing crises in the US and some other important countries, and in particular by the financial crisis that has recently intensified. The downswing will continue this year and for some time during 2009, and will only come to an end later next year if governments and central banks succeed in stabilizing financial markets in the coming months. In this case, lower prices of commodities and still high growth dynamics in important emerging markets countries will lead to a tentative revival of the world economy.
The German economy is on the brink of a recession. It is particularly vulnerable to a global downswing because exports of investment goods are of upmost importance for the overall economy. Because the uncertainty about the worldwide effects of the financial crisis is very high, the forecast is split. A more probable scenario is based on the assumption of a stabilizing world economy. In this scenario, the growth rate of the German economy in 2009 is 0.2%. The second scenario is based on the assumption of a worldwide recession next year and forecasts that German GDP will shrink by 0.8% in 2009.
Concerning policy, the institutes recommend a strengthening of the capital base of banks via injection of government money. This should be done in a way that gives incentives to banks for attracting additional capital from private sources.
A special chapter of the report analyzes the nature and causes of the price hikes of energy and commodities in the first half of 2008.

Industry Specialization, Diversity and the Efficiency of Regional Innovation Systems
Michael Fritsch, Viktor Slavtchev
Determinants of Innovative Behaviour,
2008
Abstract
Innovation processes are characterized by a pronounced division of labor between actors. Two types of externality may arise from such interactions. On the one hand, a close location of actors affiliated to the same industry may stimulate innovation (MAR externalities). On the other hand, new ideas may be born by the exchange of heterogeneous and complementary knowledge between actors, which belong to different industries (Jacobs’ externalities). We test the impact of both MAR as well as Jacobs’ externalities on innovative performance at the regional level. The results suggest an inverted u-shaped relationship between regional specialization in certain industries and innovative performance. Further key determinants of the regional innovative performance are private sector R&D and university-industry collaboration.

How Does Industry Specialization Affect the Efficiency of Regional Innovation Systems?
Michael Fritsch, Viktor Slavtchev
Jena Economic Research Papers, Nr. 2008-058,
No. 58,
2008
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 spillovers within the private sector as well as from public research institutions. The impact of both the specialization and the additional factors is, however, different for regions at different efficiency levels.

Specialization as Strategy for Business Incubators: An Assessment of the Central German Multimedia Center
Michael Schwartz, Christoph Hornych
Technovation,
No. 7,
2008
Abstract
The literature on business incubators (BIs) mainly discusses findings of incubators that do not restrict themselves to specific sectors (diversified incubators). There is a strong disregard of the possible benefits arising from the concept of a sector-specialized business incubator (SBI), although this concept has become more important in recent years. In Germany, about 19% of the incubators can be characterized as being specialized. Since 1999, nearly one-third of all new BIs in Germany opened with a sector-specific focus. This study attempts to approach this research question by examining the advantages and deficiencies of this concept and to address them with empirical observations from an SBI in the city of Halle (Germany), which has an explicit sector-focus on the media industry (MI). We identify key benefits arising from such an incubator concept: (1) high quality premises and equipment, (2) improvement of service and consultancy offerings and (3) image effects for the location. We also find deficiencies of an SBI especially regarding internal networking activities and promotion of linkages to universities. Furthermore a negative working climate impedes interaction. This study offers implications for firms, incubator managers and local policy-makers who are concerned with the instrument of an SBI.

Technologie- und Gründerzentren im Lichte von Diversifizierung versus Spezialisierung
Michael Schwartz, Christoph Hornych
IWH Discussion Papers,
No. 7,
2008
Abstract
In Germany, a growing tendency can be observed to focus business incubators (BIs) and technology centers and their respective support elements and processes as well as the selection criteria applied by the incubator management on firms from solely one sector or few but complementary sectors and their specific needs and requirements. These are called specialized business incubators (SBIs). Despite the increasing importance of specialization strategies of business incubators as local and regional policy instruments, there are no reliable empirical examinations of the specifics, and advantages in particular, of SBIs compared to more diversified BIs. On the basis of survey-data, that comprises responses from 161 actual firms incubated in 13 diversified BIs and 13 specialized BIs in Germany, this study investigates the mechanisms within the specific context of specialized BIs and their value-added contribution versus the more diversified incubation model. For the first time, this study provides large-scale empirical evidence concerning the effects of adopting a specialization strategy in the context of business incubation.

Culture as a Base for Efficient Economic Systems
Ulrich Blum
Wirtschaft im Wandel,
No. 2,
2008
Abstract
Globalization puts the German economic model, the so-called social market economy, under pressure. Constituting elements of this model are fundamental social and economic values. Globalization puts some of these values under pressure and creates inefficiencies because the costs of running the social and economic fabric rise. This is an important justification to inquire into the normative foundations of economic efficiency The following article discusses to what extent culture is a base for efficient economic systems. Information theory is regarded as a key element for explaining social change. The arguments are based on institutional economics with a special view on transaction costs and on cooperation structures. It is shown that specific information technologies promote forms of cooperation, which influence institutional arrangements. The related information technologies themselves are part of the cultural system and its value structures. As a consequence, competition among economic systems favours certain combinations of technologies, cultural arrangements and economic systems. In as much as cultural competition precedes economic competition in the sense of a certain way of thinking, the cultural system can be regarded as a strategic competitive parameter for an economy.

Does Qualification Drive Innovation? A Microeconometric Analysis Using Linked-employer-employee Data
Bianca Brandenburg, Jutta Günther, Lutz Schneider
IWH Discussion Papers,
No. 10,
2007
Abstract
Degree-level science and engineering skills as well as management and leadership skills are often referred to as a source of innovative activities within companies. Broken down by sectoral innovation patterns, this article examines the role of formal education and actual occupation for product innovation performance in manufacturing firms within a probit model. It uses unique micro data for Germany (LIAB) that contain detailed information about innovative activities and the qualification of employees. We find significant differences of the human capital endowment between sectors differentiated according to the Pavitt classification. Sectors with a high share of highly skilled employees engage in product innovation above average (specialized suppliers and science based industries). According to our hitherto estimation results, within these sectors the share of highly skilled employees does not, however, substantially increase the probability to be an innovative firm.

Innovations as driving force of the knowledge society – concepts and contemporary theoretical approaches
Jutta Günther, Björn Jindra
Wirtschaft im Wandel,
No. 9,
2007
Abstract
In response to the question what secures Europe’s future competitiveness, it is often in the context of “knowledge society” referred to location advantages for research and development (R&D), innovation and knowledge. Respective point of view is not only represented by decision makers of high-duty industrial countries, but also by so called catching up economies in Central and Eastern Europe as well as Asia. The present article deals against the background of current innovation theoretic approaches with the question of what indeed constitutes the abstract notion of the knowledge society, which actors play a role and how R&D and innovation are geographically distributed. Systemic approaches are outlined, which place emphasis on the relation among different knowledge generating actors, in particular among science and economy. In effort to elucidate the geographical distribution of R&D and innovation the authors refer to the regional economic theory, which constitute the reasons why such processes are marked by spatial concentration. Thereby, the hypotheses are competing in associating the spatial concentration with either sectoral specialization or diversification. The article shows the domination of multinational companies of research and development (R&D) in the private sector and that these businesses connect regional centers of innovations beyond national borders. Based on the theory of technological accumulation and internationalization of companies, the globalization of R&D and innovation processes are explained. Thereby, it must be recognized that a hierarchy of regional innovation systems is emerging in which the disparities are increasing both at home and abroad.
