Effectiveness of Competition Law: A Panel Data Analysis
Franz Kronthaler
IWH Discussion Papers,
No. 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.

Effects of Entrepreneurship Education at Universities
S. Laspita, H. Patzelt, Viktor Slavtchev
Jena Economic Research Papers,
No. 25,
2012
Abstract
This study analyzes the impact of entrepreneurship education at universities on the intentions of students to become entrepreneurs or self-employed in the short-term (immediately after graduation) and in the long-term (five years after graduation). A difference-in-differences approach is applied that relates changes in entrepreneurial intentions to changes in the attendance of entrepreneurship classes in the same period. To account for a potential bias due to self-selection into entrepreneurship classes, only individuals having no prior entrepreneurial intentions are analyzed. Our results indicate a stimulating effect of entrepreneurship education on students’ intentions to become entrepreneurs or self-employed in the long-term but a discouraging effect on their intentions in the short-term. These results support the conjecture that entrepreneurship education provides more realistic perspectives on what it takes to be an entrepreneur, resulting in ‘sorting’. Overall, the results indicate that entrepreneurship education may improve the quality of labor market matches, the allocation of resources and talent, and increase social welfare. Not distinguishing between short- and long-term intentions may lead to misleading conclusions regarding the economic and social impact of entrepreneurship education.

A Professor Like Me: The Influence of Instructor Gender on College Achievement
Florian Hoffmann, Philip Oreopoulos
Journal of Human Resources,
No. 2,
2009
Abstract
Many wonder whether teacher gender plays an important role in higher education by influencing student achievement and subject interest. The data used in this paper help identify average effects from male and female college students assigned to male or female teachers. We find instructor gender plays only a minor role in determining college student achievement. Nevertheless, the small effects provide evidence that gender role models matter to some college students. A same-sex instructor increases average grade performance by at most 5 percent of its standard deviation and decreases the likelihood of dropping a class by 1.2 percentage points.

A Community College Instructor Like Me: Race and Ethnicity Interactions in the Classroom

American Economic Review,
No. 8,

Abstract
Administrative data from a large and diverse community college are used to examine if underrepresented minority students benefit from taking courses with underrepresented minority instructors. To identify racial interactions we estimate models that include both student and classroom fixed effects and focus on students with limited choice in courses. We find that the performance gap in terms of class dropout rates and grade performance between white and underrepresented minority students falls by 20 to 50 percent when taught by an underrepresented minority instructor. We also find these interactions affect longer term outcomes such as subsequent course selection, retention, and degree completion.

Professor Qualities and Student Achievement
Florian Hoffmann, Philip Oreopoulos
Review of Economics and Statistics,
No. 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,
No. 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.

Independent State Aid Control in the Enlarged European Union

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,
No. 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.
