Centre for Evidence-based Policy Consulting (IWH-CEP)

The Centre for Evidence-based Policy Consulting (IWH-CEP) of the IWH was founded in 2014. This is a platform, which bundles up activities in research, teaching, and policy consulting and is structured with the objective of creating better foundations for a causal analysis of policy instruments in Germany.

IWH-CEP is designed as a service unit and supports the activities in the research groups by providing access to a supra-regional research and policy consulting network as well as access to data sets for causal analyses. IWH-CEP lies at the interface between three areas of responsibility and carries out coordination functions between them.

Centre for Evidence-based Policy Consulting (IWH-CEP)

The government intervenes in the market mechanism through a lot of policy instruments in order to achieve various economic objectives. However, for policy makers, it is important to know whether the originally intended objectives are also achieved. Scientific methods can make a significant contribution to this. These are necessary to establish a clear connection between a policy instrument and its effect. Against this background, the Centre for Evidence-based Policy Consulting (IWH-CEP) at the IWH was founded.

Research and Policy Consulting

Research and policy consulting take place in the research groups. At present, the "Joint Task of 'Improving the Regional Economic Structure'" in the Federal State of Saxony-Anhalt (which is the most important regional policy support scheme in Germany) is being evaluated. This project is intended as a pilot study. Evaluation techniques that are successful in this pilot study will be applied in the context of other policy support schemes. The project is carried out under the responsibility of IWH Research Group "The Performance of Firms and Regions". Topics from the Department of Financial Markets shall also be handled in future, and namely, how regulation affects capital allocation.

Set-up of a Network

IWH-CEP is part of the initiative for "Evidence-based Economic Policy", which is established by the Verein für Socialpolitik (German Economic Association). Through the connection with the initiative, visibility and knowledge transfer should be guaranteed in the scientific and political community.

Set-up and Maintenance of Databases

The major challenge in the analysis of effects of government interventions today lies in the development of administrative (funding) data. An IWH R&D Micro Database is set up, maintained and completed according to the (current) specialisation in the analysis of effects of industrial policy support schemes. Information about the funded projects alone is not sufficient to conduct causal analyses – corporate data of the official and commercial statistics must be referred to; this is organised using record linkage techniques. This task is perspectively carried out at the IWH Research Data Centre.

Joint R&D Subsidies, Related Variety, and Regional Innovation

T. Broekel Matthias Brachert M. Duschl T. Brenner

in: International Regional Science Review , forthcoming

Abstract

Subsidies for research and development (R&D) are an important tool of public R&D policy, which motivates extensive scientific analyses and evaluations. This article adds to this literature by arguing that the effects of R&D subsidies go beyond the extension of organizations’ monetary resources invested into R&D. It is argued that collaboration induced by subsidized joint R&D projects yield significant effects that are missed in traditional analyses. An empirical study on the level of German labor market regions substantiates this claim, showing that collaborative R&D subsidies impact regions’ innovation growth when providing access to related variety and embedding regions into central positions in cross-regional knowledge networks.

Die Analyse kausaler Effekte wirtschaftspolitischer Maßnahmen – Das Zentrum für evidenzbasierte Politikberatung am IWH (IWH-CEP)

Matthias Brachert Eva Dettmann Mirko Titze

in: Wirtschaft im Wandel , No. 5, 2015

Abstract

In Deutschland besteht ein enormer Bedarf an evidenzbasierter Politikberatung. Viele wirtschaftspolitische Interventionen werden bislang nicht umfassend evaluiert, und falls doch, wenden die wenigsten Untersuchungen geeignete Verfahren der Kausalanalyse an, um einen ursächlichen Zusammenhang zwischen der Intervention und dem Erreichen von wirtschaftspolitischen Zielen zu identifizieren. Das Leibniz-Institut für Wirtschaftsforschung Halle hat für diese Aufgabe das Zentrum für evidenzbasierte Politikberatung (IWH-CEP) eingerichtet. Eine Pilotstudie zu den Wirkungen der betrieblichen Investitionsförderung ist bereits angelaufen.

The Structure and Evolution of Intersectoral Technological Complementarity in R&D in Germany from 1990 to 2011

Matthias Brachert T. Broekel

in: IWH Discussion Papers , No. 13, 2014

Abstract

Technological complementarity is argued to be a crucial element for effective Research and Development (R&D) collaboration. The real structure is, however, still largely unknown. Based on the argument that organizations’ knowledge resources must fit for enabling collective learning and innovation, we use the co-occurrence of firms in collaborative R&D projects in Germany to assess inter-sectoral technological complementarity between 129 sectors. The results are mapped as complementarity space for the Germany economy. The space and its dynamics from 1990 to 2011 are analyzed by means of social network analysis. The results illustrate sectors being complements both from a dyadic and portfolio/ network perspective. This latter is important, as complementarities may only become fully effective when integrated in a complete set of different knowledge resources from multiple sectors. The dynamic perspective moreover reveals the shifting demand for knowledge resources among sectors at different time periods.

Actors and Interactions – Identifying the Role of Industrial Clusters for Regional Production and Knowledge Generation Activities

Mirko Titze Matthias Brachert Alexander Kubis

in: Growth and Change , No. 2, 2014

Abstract

This paper contributes to the empirical literature on systematic methodologies for the identification of industrial clusters. It combines a measure of spatial concentration, qualitative input–output analysis, and a knowledge interaction matrix to identify the production and knowledge generation activities of industrial clusters in the Federal State of Saxony in Germany. It describes the spatial allocation of the industrial clusters, identifies potentials for value chain industry clusters, and relates the production activities to the activities of knowledge generation in Saxony. It finds only a small overlap in the production activities of industrial clusters and general knowledge generation activities in the region, mainly driven by the high-tech industrial cluster in the semiconductor industry. Furthermore, the approach makes clear that a sole focus on production activities for industrial cluster analysis limits the identification of innovative actors.

Im Fokus: Geförderte FuE-Verbundprojekte: Sächsische Akteure wählen zunehmend Partner in räumlicher Nähe

Mirko Titze Matthias Brachert Wilfried Ehrenfeld

in: Wirtschaft im Wandel , No. 3, 2013

Abstract

Externe Kooperationen bei innovativen Projekten sind mit einer Reihe von Vorteilen verbunden. Oft werden solche Projekte durch Kooperationen überhaupt erst möglich. Die Literatur stellt dabei insbesondere den Austausch von Wissen heraus. Für den Austausch einer ganz besonderen Form des Wissens, des so genannten nicht kodifizierten Wissens, ist oftmals räumliche Nähe erforderlich, da nicht kodifiziertes Wissen überwiegend durch persönliche Kontakte ausgetauscht wird. Der Bund und die Länder wenden eine ganze Reihe von Förderprogrammen an, die Anreize zur Aufnahme von innovativen Kooperationsprojekten bieten. Der vorliegende Beitrag analysiert die Kooperationsstrukturen innerhalb geförderter Verbundprojekte des Bundes in den Zeiträumen 1995 bis 2000 und 2005 bis 2010. Die Untersuchung richtet sich auf den Freistaat Sachsen. Es zeigt sich, dass die sächsischen Akteure im zweiten Zeitraum mehr Partner innerhalb Sachsens und der ostdeutschen Länder gewählt haben als in der ersten Periode. Dies spricht offenbar dafür, dass sächsische Partner attraktiver werden, und ermöglicht durch die räumliche Nähe den stärkeren Austausch von nicht kodifiziertem Wissen, welches wichtig für den Erfolg von Innovationsaktivitäten einer Region ist.
