Abstract
Empirical evidence on the evolution of innovation networks within high-tech industries is still scant. We investigate network formation processes by analyzing the timing of firms to enter R&D cooperations, using data on laser source manufacturers in Germany, 1990-2010. Network measures are constructed from a unique industry database that allows us to track both the formation and the termination of ties. Regression results reveal that a firm's knowledge endowment (and cooperation experience) shortens the duration to first (and consecutive) cooperation events. The previous occupation of strategic network positions is closely related to the establishment of further R&D cooperations at a swift pace. Geographic co-location produces mixed results in our analysis.

Effects of Specification Choices on Efficiency in DEA and SFA
Michael Koetter, Aljar Meesters
Efficiency and Productivity Growth: Modelling in the Financial Services Industry,
2013
Abstract
This chapter assesses the sensitivity of bank cost-efficiency scores obtained with stochastic frontier analysis and data envelopment analysis. We compare CE scores of either type for a large cross-country sample of EU banks from 1996 until 2010. The results show that CE measures differ considerably depending on specification choices across parametric and nonparametric methods. The chapter documents the reasons for these differences in terms of theoretical, sample, and further specification choices.

Gemeindegröße, Verwaltungsform und Effizienz der kommunalen Leistungserstellung – Das Beispiel Sachsen-Anhalt

Abstract
Der Beitrag befasst sich am Beispiel Sachsen-Anhalts mit der Frage nach den Determinanten der Effizienz der kommunalen Leistungserstellung. Im Vordergrund stehen dabei der Einfluss der Gemeindegröße, der Verwaltungsform sowie von siedlungsstrukturellen, demographischen und räumlichen Faktoren. Dazu wird eine nichtparametrische Effizienzmessung (Data Envelopment Analysis bzw. der Convex-order-m-Ansatz nach Daraio und Simar) durchgeführt. Im Unterschied zu vergleichbaren Studien setzt die Untersuchung dabei auf der konsolidierten Ebene der Verwaltungsgemeinschaften und Einheitsgemeinden an, da wesentliche Kompetenzen auf der gemeinsamen Verwaltungsebene angesiedelt sind. Die Ergebnisse zeigen, dass Verwaltungsverbände oder -gemeinschaften keinen signifikanten Effizienznachteil gegenüber Einheitsgemeinden aufweisen müssen. Ferner deuten die Analysen zur Skaleneffizienz darauf hin, dass die meisten sachsen-anhaltischen Gemeinden durch die Bildung von Verwaltungs-gemeinschaften 2004 eine weitgehend effiziente „Betriebsgröße“ hatten. Demogra-phische und siedlungsstrukturelle Faktoren haben außerdem einen maßgeblichen Einfluss auf die technische Effizienz der Städte und Gemeinden: Während eine höhere Bevölkerungsdichte zumindest teilweise effizienzfördernd ist, wirken ein höherer Seniorenanteil, aber auch eine positive Bevölkerungsentwicklung tendenziell eher effizienzmindernd. Die Berücksichtigung räumlicher Zusammenhänge in der Effizienzschätzung ist ein komplexes Problem, das bisher nur unzureichend gelöst wurde. Allerdings zeigten die Schätzergebnisse für Moran’s I zwar größtenteils signifikante, aber trotzdem nur geringe bis mäßige Zusammenhänge zwischen den einzelnen Input- und Outputgrößen auf. Daher ist hier eine wesentliche Verzerrung der Ergebnisse nicht zu befürchten, wenn räumliche Zusammenhänge vernachlässigt werden. Auch konnte nicht nach-gewiesen werden, dass Umlandgemeinden von der Nähe zu Kernstädten in Form größerer Effizienz ihrer Leistungserstellung profitieren.

Natural-resource or Market-seeking FDI in Russia? An Empirical Study of Locational Factors Affecting the Regional Distribution of FDI Entries
K. Gonchar, Philipp Marek
HSE Working Papers, Series: Economics, WP BRP 26/EC/2013,
2013
Abstract
This paper analyzes the spatial distribution of foreign direct investment (FDI) across regions in Russia. Our analysis employs data on Russian firms with a foreign investor during the 2000-2009 period and links regional statistics in the conditional logit model. The main findings are threefold. First, we conclude that market-related factors and the availability of natural resources are important factors in attracting FDI. Second, existing agglomeration economies encourage foreign investors. Third, the findings imply that service-oriented FDI co-locates with extraction industries in resource-endowed regions.

Natural-resource or Market-seeking FDI in Russia? An Empirical Study of Locational Factors Affecting the Regional Distribution of FDI Entries

No. 3,
2013
Abstract
This paper conducts an empirical study of the factors that affect the spatial distribution of foreign direct investment (FDI) across regions in Russia; in particular, this paper is concerned with those regions that are endowed with natural resources and market-related benefits. Our analysis employs data on Russian firms with a foreign investor during the 2000-2009 period and linked regional statistics in the conditional logit model. The main findings are threefold. First, we conclude that one theory alone is not able to explain the geographical pattern of foreign investments in Russia. A combination of determinants is at work; market-related factors and the availability of natural resources are important factors in attracting FDI. The relative importance of natural resources seems to grow over time, despite shocks associated with events such as the Yukos trial. Second, existing agglomeration economies encourage foreign investors by means of forces generated simultaneously by sector-specific and inter-sectoral externalities. Third, the findings imply that service-oriented FDI co-locates with extraction industries in resource-endowed regions. The results are robust when Moscow is excluded and for subsamples including only Greenfield investments or both Greenfield investments and mergers and acquisitions (M&A).

Vertical Grants and Local Public Efficiency
Ivo Bischoff, Peter Bönisch, Peter Haug, Annette Illy
Abstract
This paper analyses the impact of vertical grants on local public sector efficiency. First, we develop a theoretical model in which the bureaucrat sets the tax price while voters choose the quantity of public services. In this model, grants reduce efficiency if voters do not misinterpret the amount of vertical grants the local bureaucrats receive. If voters suffer from fiscal illusion, i.e. overestimate the amount of grants, our model yields an ambiguous effect of grants on efficiency. Second, we use the model to launch a note of caution concerning the inference that can be drawn from the existing cross-sectional studies in this field: Taking into account vertical financial equalization systems that reduce differences in fiscal capacity, empirical studies based on cross-sectional data may yield a positive relationship between grants and efficiency even when the underlying causal effect is negative. Third, we perform an empirical analysis for the German state of Saxony-Anhalt, which has implemented such a fiscal equalization system. We find a positive relationship between grants and efficiency. Our analysis shows that a careful reassessment of existing empirical evidence with regard to this issue seems necessary.

Grant Dependence, Regulation and the Effects of Formula-based Grant Systems on German Local Governments: A Data Report for Saxony-Anhalt
Peter Haug
IWH Discussion Papers,
No. 2,
2013
Abstract
Recent empirical studies have found – seemingly − efficiency-enhancing effects of vertical grants on local public service provision. The main purpose of this paper is to prepare an elaborate theoretical and empirical analysis of these contradictory results. Therefore, it investigates if certain fiscal and institutional conditions (fiscal stress, fiscal rank-preserving vertical grant systems, input- and output regulation), that might help to explain these empirical findings, are characteristic of at least some parts of the local government sector or certain regions. The German state of Saxony-Anhalt is chosen for case study purposes. The main results are: First, the local governments suffer from severe fiscal problems such as high grant dependency, low tax revenues and the prevalent inability to finance investments by own resources. Second, the output- and input-regulation density of certain mandatory municipal services (schools, childcare facilities, fire protection) is high. Finally, the most important vertical grant category for local governments, the formula-based grants (“Schlüsselzuweisungen”), can be described as mainly exogenous, unconditional block grants that in most cases preserve the relative fiscal position of the grant recipients.

Teacher Experience and the Class Size Effect - Experimental Evidence
Steffen Müller
Journal of Public Economics,
2013
Abstract
We analyze teacher experience as a moderating factor for the effect of class size reduction on student achievement in the early grades using data from the Tennessee STAR experiment with random assignment of teachers and students to classes of different sizes. The analysis is motivated by the high costs of class size reductions and the need to identify the circumstances under which this investment is most rewarding. We find a class size effect only for senior teachers. The effect exists at all deciles of the achievement distribution but is less pronounced at lower deciles. We further show that senior teachers outperform rookies only in small classes. Interestingly, the class size effect is likely due to a higher quality of instruction in small classes.

How does Institutional Setting Affect the Impact of EU Structural Funds on Economic Cohesion? New Evidence from Central and Eastern Europe
Marina Grusevaja, Toralf Pusch
Journal of Common Market Studies,
2012
Abstract
Structural Funds are the main instrument of the EU Cohesion Policy. Their effective use is subject to an ongoing debate in political and scientific circles. European fiscal assistance under this heading should promote economic and social cohesion in the member states of the European Union. Recently the domestic institutional capacity to absorb, to distribute and to invest Structural Funds effectively has become a crucial determinant of the cohesion process and has attracted attention of the scientific community. The aim of this study is to shed light on the effectiveness of Structural Funds in the countries of the first Central and Eastern European enlargement round in 2004. Using regional data for these countries we have a look on the impact of several institutional governance variables on the effectiveness of Structural Funds. In the interpretation of results reference is made to regional economics. Results of the empirical analysis indicate an influence of certain institutional variables on the effectiveness of Structural Funds in the new member states.
