Abstract
This paper examines the properties of qualitative inflation expectations collected from economic experts for Germany. It describes their characteristics relating to rationality and Granger causality. An out-of-sample simulation study investigates whether this indicator is suitable for inflation forecasting. Results from other standard forecasting models are considered and compared with models employing survey measures. We find that a model using survey expectations outperforms most of the competing models. Moreover, we find some evidence that the survey indicator already contains information from other model types (e. g. Phillips curve models). However, the forecast quality may be further improved by completely taking into account information from some financial indicators.

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.

Incubating an Illusion? Long-term Incubator Firm Performance after Graduation
Michael Schwartz
Growth and Change,
No. 4,
2011
Abstract
Local economic development policies worldwide perceive business incubation as an effective measure to promote regional growth through the support of young and innovative ventures. The common assumption is that incubation promotes firm growth, in particular after these firms graduated from their incubator organizations. This article investigates the long-term performance of 324 graduate firms from five German business incubators (incubated between 1990 and 2006) after they have (successfully) completed their incubation. The present study does not suffer from a survivor bias, meaning that performance data of non-surviving firms is also included. Using employment and sales measures as performance indicators, this study contributes to our knowledge with regard to long-term incubator firm performance after graduation. While in the first years after graduation there is significant growth of formerly incubated firms, further results do not support the presumption of continuous firm growth beyond incubation. A minority of graduate firms exhibits a strong increase in performance, but the majority of firms do not experience considerable growth.

The Financial Crisis from a Forecaster’s Perspective
Katja Drechsel, Rolf Scheufele
Abstract
This paper analyses the recession in 2008/2009 in Germany, which is very different from previous recessions, in particular regarding its cause and magnitude. We show to what extent forecasters and forecasts based on leading indicators fail to detect the timing and the magnitude of the recession. This study shows that large forecast errors for both expert forecasts and forecasts based on leading indicators resulted during this recession which implies that the recession was very difficult to forecast. However, some leading indicators (survey data, risk spreads, stock prices) have indicated an economic downturn and hence, beat univariate time series models. Although the combination of individual forecasts provides an improvement compared to the benchmark model, the combined forecasts are worse than several individual models. A comparison of expert forecasts with the best forecasts based on leading indicators shows only minor deviations. Overall, the range for an improvement of expert forecasts during the crisis compared to indicator forecasts is relatively small.

The Political Setting of Social Security Contributions in Europe in the Business Cycle
Toralf Pusch, Ingmar Kumpmann
IWH Discussion Papers,
No. 4,
2011
Abstract
Social security revenues are influenced by business cycle movements. In order to
support the working of automatic stabilizers it would be necessary to calculate social insurance contribution rates independently from the state of the business cycle. This paper investigates whether European countries set social contribution rates according to such a rule. By means of VAR estimations, country-specific effects can be analyzed – in contrast to earlier studies which used a panel design. As a result, some countries under investigation seem to vary their social contribution rates in a procyclical way.

Exploring the Economic Convergence in the EU New Member States by Using Nonparametric Models
Monica Raileanu Szeles
IWH Discussion Papers,
No. 2,
2011
Abstract
This paper analyzes the process of real economic convergence in the New Member States (NMS) bein g formerly centrally planned economies, using nonparametric methods instead of conventional parametric measurement tools like beta and sigma models. This methodological framework allows the examining of the relative income distribution in different periods of time, the number of modes of the density distribution, the existence of “convergence clubs” in the distribution and the hypothesis of convergence at a single point in time. The modality tests (e.g. the ASH-WARPing procedure) and stochastic kernel are nonparametric techniques used in the empirical part of the study to examine the income distribution in the NMS area. Additionally, random effects panel regressions are used, but only for comparison reasons. The main findings of the paper are the bimodality of the income density distribution over time and across countries, and the presence of convergence clubs in the income distribution from 1995 to 2008. The findings suggest a lack of absolute convergence in the long term (1995-2008) and also when looking only from 2003 onwards. The paper concludes that, in comparison with the parametrical approach, the nonparametric one gives a deeper, real and richer perspective on the process of real convergence in the NMS area.

Identifying Industrial Clusters from a Multidimensional Perspective: Methodical Aspects with an Application to Germany
Matthias Brachert, Mirko Titze, Alexander Kubis
Papers in Regional Science,
No. 2,
2011
Abstract
If regional development agencies assume the cluster concept to be an adequate framework to promote regional growth and competitiveness, it is necessary to identify industrial clusters in a comprehensive manner. Previous studies used a diversity of methods to identify the predominant concentrations of economic activity in one industrial sector in a region. This paper is based on a multidimensional approach developed by Titze et al. With the help of the combination of concentration measures and input–output methods they were able to identify horizontal and vertical dimensions of industrial clusters. This paper aims to refine this approach by using a superior measure of spatial concentration and by integrating information about spatial interdependence of industrial cluster structures to contribute to a more adequate framework for industrial cluster identification.

Economic Structure and Regional Performance in Germany, 2002-2007

No. 2,

Abstract
This paper explores the impact of industrial clusters on regional growth at the German labour market region level using a regional convergence model. Based on the results of an exploratory study of the geography of German industrial clusters, we are able to differentiate the impact of industrial clustering from a horizontal and a vertical perspective while taking regional convergence into consideration. The results indicate that in addition to an all-German process of convergence, a specific East German one can be identified. The different types of industrial clusters show mixed effects within this framework. While vertically isolated industrial clusters have a negative impact on regional growth in this period, positive growth effects can be identified when industrial clusters show an intra-regional vertical interconnectedness.
