New IWH publication takes stock: “United country – three decades after the Wall came down”
How is Germany’s economy faring 30 years after the fall of the Berlin Wall? A new publication by the Halle Institute for Economic Research (IWH) uses illustrative maps and graphs to show how the Federal Republic has developed compared to other countries and how economic unification has progressed. The publication presents many new findings, including on productivity differences between east and west, urban and rural development, as well as the availability of skilled labour.

Do Diasporas Affect Regional Knowledge Transfer within Host Countries? A Panel Analysis of German R&D Collaborations
Lutz Schneider, Alexander Kubis, Mirko Titze
Regional Studies,
No. 1,
2019
Abstract
Interactive regional learning involving various actors is considered a precondition for successful innovations and, hence, for regional development. Diasporas as non-native ethnic groups are regarded as beneficial since they enrich the creative class by broadening the cultural base and introducing new routines. Using data on research and development (R&D) collaboration projects, the analysis provides tentative evidence that the size of diasporas positively affects the region’s share of outward R&D linkages enabling the exchange of knowledge. The empirical analysis further confirms that these interactions mainly occur between regions hosting the same diasporas, pointing to a positive effect of ethnic proximity rather than ethnic diversity.

Identifying Cooperation for Innovation – A Comparison of Data Sources
Michael Fritsch, Matthias Piontek, Mirko Titze
Abstract
The value of social network analysis is critically dependent on the comprehensive and reliable identification of actors and their relationships. We compare regional knowledge networks based on different types of data sources, namely, co-patents, co-publications, and publicly subsidised collaborative Research and Development projects. Moreover, by combining these three data sources, we construct a multilayer network that provides a comprehensive picture of intraregional interactions. By comparing the networks based on the data sources, we address the problems of coverage and selection bias. We observe that using only one data source leads to a severe underestimation of regional knowledge interactions, especially those of private sector firms and independent researchers. The key role of universities that connect many regional actors is identified in all three types of data.

Abstract
The economic situation in German establishments improved even further in 2017. The development of wages, however, reflects this economic growth only partly. Compared to 1997, the wage differential between large and small establishments increased considerably – with substantially lower wages paid in East Germany in general. The wage differential of about 19 percent between East and West Germany can to some extent be explained in a multivariate analysis (Blinder-Oaxaca decomposition) showing that the main cause for the wage gap is the productivity gap between East German and West German establishments; other structural heterogeneities like sector composition, industrial relations and size structure seem not to contribute to an explanation of this gap. The overall positive economic development in Germany is associated with a further growth in total employment and with increased labor market dynamics, especially regarding employee turnover. Turnover rates, however, are very heterogeneous among sectors, ranging from 23 percent in the accommodation and food service sector and less than five percent in public administration. Also the demand for skilled personnel continued to grow. Yet for the first time, not even two thirds of the posted job vacancies could be filled in 2017. With over fifty percent, this non-occupancy quota is particularly high in the construction industry. Also small and very small establishments face serious recruitment problems. The structure of formal occupational skill requirements did not change very much over recent years, but the increasing use of digital technologies changes everyday job requirements and may lead to a rising workload for employees. Looking at the personnel structure in the German economy, a growing share of atypical employment becomes apparent, especially in form of part-time jobs. The proportion of marginal employment remains relatively stable and is comparatively high in sectors with less specific knowledge requirements and strong cyclical and/or seasonal fluctuations like is the case in accommodation and food service sector or personal services sector. Since 2010, the proportion of establishments authorized to provide in-company vocational training has declined constantly and now accounts for 53 percent of the establishments in Germany. About one half of these establishments do actually train apprentices. The share of vacant apprenticeships further increased in 2017 to about one quarter of all apprenticeships offered, in East Germany even to more than one third. As in recent years, the share of establishments supporting further training of their employees remained stable at about fifty percent and the proportion of employees participating in training is still about one third. In East Germany these figures prove to be slightly higher.

Does it Payoff to Research Economics? A Tale of Citation, Knowledge and Economic Growth in Transition Countries

Physica A: Statistical Mechanics and its Applications,

2018
Abstract
There are many economic theories that promote human capital as a key driver of a country’s economic growth, but it is challenging to test this theory empirically on a country level and causally interpret the coefficients due to several identification problems. We tried to answer this particular question by using a quasi-natural experiment that happened quarter century ago – the fall of communist block in Eastern Europe. We use a shock to a particular scientific field – economics, to test whether the future investment into that particular field resulted in increased welfare and economic growth. The economics paradigm that was governing all of the communist block ceased to exist. Human capital depreciated over night and all communist countries had to transit from planned economy to a market economy. In the following years countries had to adapt to market economy through additional investment in human capital and research. We find that countries which lack both of the two fourth mentioned components had 25 years later a relatively lower economic growth and wealth. Unlike economics, other fields such as physics and medicine did not go through the same process so we use them as a placebo effect for our study. We find that the relative ratio of citations between economics and physics in post-communist countries is increasing only 15 years after the “paradigm” shock which gives a suggestive evidence that timing of investment into particular scientific field matters the most.

Africa’s Skill Tragedy
Jan Bietenbeck, Marc Piopiunik, Simon Wiederhold
Journal of Human Resources,
No. 3,
2018
Abstract
We study the importance of teacher subject knowledge for student performance in Sub-Saharan Africa using unique international assessment data for sixth-grade students and their teachers. To circumvent bias due to unobserved student heterogeneity, we exploit variation within students across math and reading. Teacher subject knowledge has a modest impact on student performance. Exploiting vast cross-country differences in economic development, we find that teacher knowledge is effective only in more developed African countries. Results are robust to adding teacher fixed effects and accounting for potential sorting based on subject-specific factors.

Do Venture Capital Firms Benefit from a Presence on Boards of Directors of Mature Public Companies?
Iftekhar Hasan, Arif Khurshed, Abdulkadir Mohamed, Fan Wang
Journal of Corporate Finance,
2018
Abstract
This paper examines the benefits to venture capital firms of their officers holding directorships in mature public companies in terms of fundraising and investment performance. Our empirical results show that venture capital firms raise more funds, set higher fund-raising targets, and are more likely to successfully exit their investments post-appointment of their officers to boards of directors of S&P 1500 companies. Directorship status in mature public firms provides venture capital firms with enhanced networks, visibility, and credibility, all of which facilitate their fundraising activities. In addition, the knowledge, expertise, and experience acquired through holding directorships in mature public firms are beneficial for their portfolio companies, as measured by the likelihood of successful exits.

R&D Collaborations and the Role of Proximity

No. 12,
2017
Abstract
R&D collaborations and the role of proximity. Regional Studies. This paper explores the impact of proximity measures on knowledge exchange measured by granted research and development (R&D) collaboration projects in German NUTS-3 regions. The results are obtained from a spatial interaction model including eigenvector spatial filters. Not only geographical but also other forms of proximity (technological, organizational and institutional) have a significant influence on the emergence of collaborations. Furthermore, the results suggest interdependences between proximity measures. Nevertheless, the analysis does not show that other forms of proximity may compensate for missing geographical proximity. The results indicate that (subsidized) collaborative innovation activities tend to cluster.

2017
Abstract
Start-ups and other entrepreneurial ventures make a significant contribution to the US economy, particularly in the tech sector, where they comprise some of the largest and most influential companies. Yet for every startup that becomes a high-profile, high-growth company like Apple, Facebook, Microsoft, and Google, many more fail. This enormous heterogeneity poses conceptual and measurement challenges for economists concerned with understanding how new businesses affect economic growth.

Benchmark Value-added Chains and Regional Clusters in R&D-intensive Industries
Reinhold Kosfeld, Mirko Titze
International Regional Science Review,
No. 5,
2017
Abstract
Although the phase of euphoria seems to be over, policy makers and regional agencies have maintained their interest in cluster policy. Modern cluster theory provides reasons for positive external effects that may accrue from interaction in a group of proximate enterprises operating in common and related fields. Although there has been some progress in locating clusters, in most cases only limited knowledge on the geographical extent of regional clusters has been established. In the present article, we present a hybrid approach to cluster identification. Dominant buyer–supplier relationships are derived by qualitative input–output analysis from national input–output tables, and potential regional clusters are identified by spatial scanning. This procedure is employed to identify clusters of German research and development-intensive industries. A sensitivity analysis reveals good robustness properties of the hybrid approach with respect to variations in the quantitative cluster composition.
