Professor Qualities and Student Achievement
Florian Hoffmann, Philip Oreopoulos
Review of Economics and Statistics,
Nr. 1,
2009
Abstract
This paper analyzes the importance of teacher quality at the college level. Instructors are matched to objective and subjective characteristics of teacher quality to estimate the impact of rank, salary, and perceived effectiveness on student performance and subject interest. Student and course fixed effects, time of day and week controls, and students' lack of knowledge about first-year instructors help minimize selection biases. Subjective teacher evaluations perform well in measuring instructor influences on students, while objective characteristics such as rank and salary do not. Overall, the importance of college instructor differences is small, but important outliers exist.

The Laffer curve revisited
Mathias Trabandt, Harald Uhlig
Journal of Monetary Economics,
Nr. 4,
2011
Abstract
Laffer curves for the US, the EU-14 and individual European countries are compared, using a neoclassical growth model featuring “constant Frisch elasticity” (CFE) preferences. New tax rate data is provided. The US can maximally increase tax revenues by 30% with labor taxes and 6% with capital taxes. We obtain 8% and 1% for the EU-14. There, 54% of a labor tax cut and 79% of a capital tax cut are self-financing. The consumption tax Laffer curve does not peak. Endogenous growth and human capital accumulation affect the results quantitatively. Household heterogeneity may not be important, while transition matters greatly.

Unabhängige Subventionskontrolle und staatliche Beihilfen in der erweiterten Europäischen Union

Unabhängige staatliche Organisationen in der Demokratie. Schriften des Vereins für Socialpolitik Bd. 337,
2013
Abstract
Die Kontrolle staatlicher Subventionen in Europa hat eine bewegte Geschichte: Bis in die 1970er haben viele europäische Staaten ausgiebig Subventionspolitik betrieben, die nach heutigen Regeln kaum möglich gewesen wären. Mit der Vertiefung des europäischen Binnenmarktes gegen Ende der 1980er und Anfang der 1990er wurden zunehmend europäische Normen für die staatliche Beihilfe-politik auf nationaler Ebene durchgesetzt. Diese Studie untersucht insbesondere die Auswirkungen der Ost-Erweiterung der Europäischen Union im Jahr 2004 auf die Unabhängigkeit der Europäischen Beihilfekontrolle. Hierfür werden neben quantitativen auch qualitative Analysen in Form von Case Studies genutzt. Die Ergebnisse zeigen, dass in den vergangenen Jahren ein einheitliches Level Playing Field zwischen den Mitgliedsstaaten entstanden ist. Auch der Status des EU Kommissars für Wettbewerb zeigt sich als stark und unabhängig und – bis auf wenige Ausnahmen - weitgehend frei von nationaler Einflussnahm.

The Relationship between Knowledge Intensity and Market Concentration in European Industries: An inverted U-Shape
Niels Krap, Johannes Stephan
IWH Discussion Papers,
Nr. 3,
2008
Abstract
This paper is motivated by the European Union strategy to secure competitiveness for Europe in the globalising world by focussing on technological supremacy (the Lisbon - agenda). Parallel to that, the EU Commission is trying to take a more economic approach to competition policy in general and anti-trust policy in particular. Our analysis tries to establish the relationship between increasing knowledge intensity and the resulting market concentration: if the European Union economy is gradually shifting to a pattern of sectoral specialisation that features a bias on knowledge intensive sectors, then this may well have some influence on market concentration and competition policy would have to adjust not to counterfeit the Lisbon-agenda. Following a review of the available theoretical and empirical literature on the relationship between knowledge intensity and market structure, we use a larger Eurostat database to test the shape of this relationship. Assuming a causality that runs from knowledge to concentration, we show that the relationship between knowledge intensity and market structures is in fact different for knowledge intensive industries and we establish a non-linear, inverted U-curve shape.

Preventing Innovative Cooperations: The Legal Exemptions Unintended Side Effect
Christian Growitsch, Nicole Nulsch, Margarethe Rammerstorfer
IWH Discussion Papers,
Nr. 6,
2008
Abstract
In 2004, European competition law had been faced with considerable changes due to the introduction of the new Council Regulation No. 1/2003. One of the major renewals was the replacement of the centralized notification system for inter-company cooperations in favor of a so-called legal exemption system. We analyze the implications of this reform on the agreements firms implement. In contrast to previous research we focus on the reform’s impact on especially welfare enhancing, namely innovative agreements. We show that the law’s intention to reduce the incentive to establish illegal cartels will be reached. However, by the same mechanism, also highly innovative cooperations might be prevented. To avoid this unintended effect, we conclude that only fines but not the monitoring activities should be increased in order to deter illegal but not innovative agreements.

A Game Theoretic Analysis of the Conditions of Knowledge Transfer by New Employees in Companies
Sidonia vonLedebur
IWH Discussion Papers,
Nr. 3,
2006
Abstract
The availability of knowledge is an essential factor for an economy in global competition. Companies realise innovations by creating and implementing new knowledge. Sources of innovative ideas are partners in the production network but also new employees coming from another company or academia. Based on a model by HECKATHORN (1996) the conditions of efficient knowledge transfer in a team are analysed. Offering knowledge to a colleague can not be controlled directly by the company due to information asymmetries. Thus the management has to provide incentives which motivate the employees to act in favour of the company by providing their knowledge to the rest of the team and likewise to learn from colleagues. The game theoretic analysis aims at investigating how to arrange these incentives efficiently. Several factors are relevant, especially the individual costs of participating in the transfer. These consist mainly of the existing absorptive capacity and the working atmosphere. The model is a 2x2 game but is at least partly generalised on more players. The relevance of the adequate team size is shown: more developers may increase the total profit of an innovation
(before paying the involved people) but when additional wages are paid to each person a greater team decreases the remaining company profit. A further result is
that depending on the cost structure perfect knowledge transfer is not always best for the profit of the company. These formal results are consistent with empirical studies to the absorptive capacity and the working atmosphere.

Foreign Subsidiaries in the East German Innovation System – Evidence from Manufacturing Industries
Jutta Günther, Björn Jindra, Johannes Stephan
IWH Discussion Papers,
Nr. 4,
2008
Abstract
This paper analyses the extent of technological capability of foreign subsidiaries located in East Germany, and looks at the determinants of foreign subsidiaries’ technological sourcing behaviour. The theory of international production underlines the importance of strategic and regional level variables. However, existing empirical approaches omit by and large regional level factors. We employ survey evidence from the “FDI micro data- base” of the IWH, that was only recently made available, to conduct our analyses. We find that foreign subsidiaries are above average technologically active in comparison to the whole East German manufacturing. This can be partially explained by the industrial structure of foreign direct investment. However, only a limited share of foreign subsidiaries with R&D and/or innovation activity source technological knowledge from the East German innovation system. If a subsidiary follows a competence augmenting strategy or does local trade, it is more likely to source technological knowledge locally. The endowment of a region with human capital and a scientific infrastructure has a positive effect too. The findings suggest that foreign subsidiaries in East Germany are only partially linked with the regional innovation system. Policy implications are discussed.

What Happened to the East German Housing Market? – A Historical Perspective on the Role of Public Funding –
Claus Michelsen, Dominik Weiß
IWH Discussion Papers,
Nr. 20,
2009
Abstract
The paper analyses the development of the East German housing market after the reunification of the former German Democratic Republic and the Federal Republic of Germany in 1990. We analyse the dynamics of the East German housing market within the framework of the well-known stock-flow model, proposed by DiPasquale and Wheaton. We show that the today observable disequilibrium to a large extend is caused by post-unification housing policy and its strong fiscal incentives to invest into the housing stock. Moreover, in line with the stylized empirical facts, we show that ‘hidden reserves’ of the housing market were reactivated since the economy of East Germany became market organized. Since initial undersupply was overcome faster than politicians expected, the implemented fiscal stimuli were too strong. In contrast to the widespread opinion that outward migration caused the observable vacancies, this paper shows that not weakness of demand but supply side policies caused the observable disequilibrium.

A Federal Long-run Projection Model for Germany
Oliver Holtemöller, Maike Irrek, Birgit Schultz
IWH Discussion Papers,
Nr. 11,
2012
Abstract
Many economic decisions implicitly or explicitly rely on a projection of the medium- or long-term economic development of a country or region. In this paper, we provide a federal long-run projection model for Germany and the German states. The model fea-tures a top-down approach and, as major contribution, uses error correction models to estimate the regional economic development dependent on the national projection. For the medium- and long-term projection of economic activity, we apply a production function approach. We provide a detailed robustness analysis by systematically varying assumptions of the model. Additionally, we explore the effects of different demographic trends on economic development.
