Abstract
This paper evaluates the New Keynesian Phillips Curve (NKPC) and its hybrid
variant within a limited information framework for Germany. The main interest rests on the average frequency of price re-optimization of firms. We use the labor income share as the driving variable and consider a source of real rigidity by allowing for a fixed firm-specific capital stock. A GMM estimation strategy is employed as well as an identification robust method that is based upon the Anderson-Rubin statistic. We find out that the German Phillips Curve is purely forward looking. Moreover, our point estimates are consistent with the view that firms re-optimize prices every two to three quarters. While these estimates seem plausible from an economic point of view, the uncertainties around these estimates are very large and also consistent with perfect nominal price rigidity where firms never re-optimize prices. This analysis also offers some explanations why previous results for the German NKPC based on GMM differ considerably. First, standard GMM results are very sensitive to the way how orthogonality conditions are formulated. Additionally, model misspecifications may be left undetected by conventional J tests. Taken together, this analysis points out
the need for identification robust methods to get reliable estimates for the NKPC.

Regional origins of employment volatility: evidence from German states
Claudia M. Buch
CES IFO Working Paper No. 2296,
2008
Abstract
Greater openness for trade can have positive welfare effects in terms of higher growth. But increased openness may also increase uncertainty through a higher volatility of employment. We use regional data from Germany to test whether openness for trade has an impact on volatility. We find a downward trend in the unconditional volatility of employment, paralleling patterns for output volatility. The conditional volatility of employment, measuring idiosyncratic developments across states, in contrast, has remained fairly unchanged. In contrast to evidence for the US, we do not find a significant link between employment volatility and trade openness.

The Role of the Human Capital and Managerial Skills in Explaining the Productivity Gaps between East and West
Wolfgang Steffen, Johannes Stephan
IWH Discussion Papers,
Nr. 11,
2007
Abstract
This paper assess determinants of productivity gaps between firms in the European transition countries and regions and firms in West Germany. The analysis is conducted at the firm level by use of a unique database constructed by field work. The determinants tested in a simple econometric regression model are focussed upon the issue of human capital and modern market-oriented management. The results are novel in as much as a solution was established for the puzzling results in related research with respect to a comparison of formal qualification between East and West. Furthermore, the analysis was able to establish that the kind of human capital and expertise mostly needed in the post-socialist firms are related to the particular requirements of a competitive marketbased economic environment. Finally, the analysis also finds empirical support for the role of capital deepening in productivity catch-up, as well as the case that the gaps in labour productivity are most importantly rooted in a more labour-intense production, which does not give rise to a competitive disadvantage.

Spillover Effects of Spatial Growth Poles - a Reconciliation of Conflicting Policy Targets?
Alexander Kubis, Mirko Titze, Joachim Ragnitz
IWH Discussion Papers,
Nr. 8,
2007
Abstract
Regional economic policy faces the challenge of two competing policy goals - reducing regional economic disparities vs. promoting economic growth. The allocation of public funds has to weigh these goals particularly under the restriction of scarce financial re- sources. If, however, some region turns out to be a regional growth pole with positive spillovers to its disadvantaged periphery, regional policies could be designed to recon- cile the conflicting targets. In this case, peripheral regions could indirectly participate in the economic development of their growing cores. We start our investigation by defining and identifying such growth poles among German regions on the NUTS 3 administrative level based on spatial and sectoral effects. Using cluster analysis, we determine significant characteristics for the general identification of growth poles. Patterns in the sectoral change are identified by means of the change in the employment. Finally, we analyze whether and to what extent these growth poles ex- ert spatial spillover effects on neighbouring regions and thus mitigate contradictory in- terests in regional public policy. For this purpose, we apply a Spatial-Cross-Regressive- Model (SCR-Model) including the change in the secondary sector which allows to con- sider functional economic relations on the administrative level chosen (NUTS 3).

Effectiveness of Competition Law: A Panel Data Analysis
Franz Kronthaler
IWH Discussion Papers,
Nr. 7,
2007
Abstract
The paper explores what macroeconomic factors can tell us about the effectiveness of recently enacted national competition laws. Qualitative evidence suggests that numerous countries fall short in implementing competition law. Furthermore, there seems to be significant differences between countries. To examine what factors might contribute to the explanation of effectiveness of competition law panel regression analysis is used. The results indicate that the level of economic development matters, however the institutional learning curve is also relevant. Furthermore, larger countries should be more concerned with competition advocacy activities than smaller countries and it seems to be the case that the problem of capture of competition law is serious in countries with high levels of corruption.

What Determines the Efficiency of Regional Innovation Systems?
Michael Fritsch, Viktor Slavtchev
Jena Economic Research Papers, Nr. 2007-006,
Nr. 6,
2007
Abstract
We assess the efficiency of regional innovation systems (RIS) in Germany by means of a knowledge production function. This function relates private sector research and development (R&D) activity in a region to the number of inventions that have been registered by residents of that region. Different measures and estimation approaches lead to rather similar assessments. We find that both spillovers within the private sector as well as from universities and other public research institutions have a positive effect on the efficiency of private sector R&D in the respective region. It is not the mere presence and size of public research institutions, but rather the intensity of interactions between private and public sector R&D that leads to high RIS efficiency. We find that relationship between the diversity of a regions’ industry structure and the efficiency of its innovation system is inversely u-shaped. Regions dominated by large establishments tend to be less efficient than regions with a lower average establishment size.

Economic 'Clusters' in East Germany: Evidence on the Location and the Characteristics of Spatially Concentrated Industries

Abstract
Im Beitrag werden empirische Befunde zur Frage präsentiert, in welchen Teilräumen Ostdeutschlands sich Branchenkonzentrationen mit „Cluster“-Qualitäten herausgebildet haben. Solche Qualitäten wurden im Rahmen der empirischen Untersuchung als gegeben angesehen, wenn ein räumlicher Branchenschwerpunkt mit Netzwerkaktivitäten und innovativen Kompetenzen einhergeht. Die Befunde zeigen, daß Branchenschwerpunkte, die die genannten Eigenschaften haben, relativ rar sind, und daß sie am ehesten in den ostdeutschen Agglomerationsräumen existieren. Vor diesem Hintergrund plädiert der Beitrag dafür, anstelle einer „Gießkannenförderung“ die Mittel der Regionalpolitik stärker räumlich zu konzentrieren zugunsten von Standorten mit Branchenschwerpunkten. Dort sollten vor allem Vernetzungen und innovative Kompetenzen gestärkt werden.

Where enterprises lead, people follow? Links between migration and FDI in Germany
Claudia M. Buch, J. Kleinert, Farid Toubal
European Economic Review,
Nr. 8,
2006
Abstract
Standard neoclassical models of economic integration are based on the assumptions that capital and labor are substitutes and that the geography of factor market integration does not matter. Yet, these two assumptions are violated if agglomeration forces among factors from specific source countries are at work. Agglomeration implies that factors behave as complements and that the country of origin matters. This paper analyzes agglomeration between capital and labor empirically. We use state-level German data to answer the question whether and how migration and foreign direct investment (FDI) are linked. Stocks of inward FDI and of immigrants have similar determinants, and the geography of factor market integration matters. There are higher stocks of inward FDI in German states hosting a large foreign population from the same country of origin. This agglomeration effect is confined to higher-income source countries.

Progressivity and flexibility in developing an effective competition regime: using experiences of Poland, Ukraine and South Africa for developing countries. Forschungsbericht innerhalb des EU-Projektes: Competition Policy Foundations for Trade Reform, Regulatory Reform, and Sustainable Development, 2005

Nr. 5,

Abstract
The paper discusses the role of the concept of special and differential treatment in the framework of regional trade agreements for the development of a competition regime. After a discussion of the main characteristics and possible shortfalls of those concepts, three case countries are assessed in terms of their experience with progressivity, flexibility, and technical and financial assistance: Poland was led to align its competition laws to match the model of the EU. The Ukraine opted voluntarily for the European model, this despite its intense integration mainly with Russia. South Africa, a developing country that emerged from a highly segregated social fabric and an economy dominated by large conglomerates with concentrated ownership. All three countries enacted (or comprehensively reformed) their competition laws in an attempt to face the challenges of economic integration and catch up development on the one hand and particular social problems on the other. Hence, their experience may be pivotal for a variety of different developing countries who are in negotiations to include competition issues in regional trade agreements. The results suggest that the design of such competition issues have to reflect country-particularities to achieve an efficient competition regime.
