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.

Why are East Germans not More Mobile? Analyzing the Impact of Social Ties on Regional Migration
Peter Bönisch, Lutz Schneider
Abstract
Individuals’ preferences in transition regions are still shaped by the former communist system. We test this ‘Communism legacy’ hypothesis by examining the impact of acculturation in a communist regime on social network participation and, as a consequence, on preferences for spatial mobility. We focus on the paradigmatic case of East Germany where mobility intentions seem to be substantially weaker than in the western part. Applying an IV ordered probit approach we firstly find that East German people acculturated in a Communist system are more invested in locally bounded informal social capital than West Germans. Secondly, we confirm that membership in such locally bounded social networks reduces the intention to move away. Thirdly, after controlling for the social network effect the mobility gap between East and West substantially reduces. Low spatial mobility of the eastern population, we conclude, is to an important part attributable to a social capital endowment characteristic to post-communist economies.

Selectivity, Social Ties and Spatial Mobility – An Analysis of Preferences for Return Migration
Lutz Schneider, Alexander Kubis, D. Wiest
Abstract
Die Abwanderung überwiegend junger, gebildeter Menschen aus Ostdeutschland wird häufig als nachteilig für die Entwicklungsfähigkeit und den Aufholprozess der Neuen Länder betrachtet. Das Phänomen der Zuwanderung – und dabei nicht zuletzt der Rückwanderung vormals Abgewanderter – findet in diesem Zusammenhang besonderes Interesse. Die vorliegende Arbeit analysiert die Rückwanderungsneigung auf Basis eines im Rahmen des DFG-Forschungsprojektes „Brain drain aus Ostdeutschland“ am Lehrstuhl für Sozialgeographie der Martin-Luther-Universität Halle-Wittenberg erhobenen Datensatzes zu den Einstellungen und Motivlagen aus Sachsen-Anhalt abgewanderter junger Menschen. Dabei wird auf folgende Aspekte besonderer Wert gelegt: die Wirkung des Arbeitsmarkterfolges nach der Abwanderung; der Einfluss sozialer Bindungen in der Herkunfts- und der Zielregion; schließlich die Selektivität der Rückwanderungsneigung. Im Ergebnis zeigt sich erstens, dass der individuelle Arbeitsmarkterfolg in der Zielregion die Rückkehrneigung verringert. Zweitens konnte die rückwanderungsfördernde Wirkung bestehender sozialer Bindungen zum Herkunftsgebiet nachgewiesen werden. Hinsichtlich der Selektivität der Rückwanderungsintentionen sind die Ergebnisse ambivalent.

Are there Gender-specific Preferences for Location Factors? A Grouped Conditional Logit-model of Interregional Migration Flows in Germany
Lutz Schneider, Alexander Kubis
Schmollers Jahrbuch,
2010
Abstract
Die vorliegende Arbeit untersucht geschlechtsspezifische Unterschiede in der Wertschätzung regionaler Standortfaktoren. Die Standortpräferenzen werden auf Basis einer Analyse von interregionalen Wanderungsströmen innerhalb Deutschlands analysiert. Die Untersuchung basiert auf einem Grouped Conditional Logit-Ansatz, wobei die Probleme der Unabhängigkeit von irrelevanten Alternativen und der Überdispersion berücksichtigt werden. Im Ergebnis zeigt sich zunächst, dass bei Frauen und Männern dieselben regionalen Charakteristika als Pull- oder aber als Push-Faktoren wirken. Geschlechtsspezifische Unterschiede werden aber hinsichtlich Stärke des Einflusses der einzelnen Faktoren sichtbar, vor allem im Hinblick auf das regionale Lohnniveau und das Angebot an Bildungseinrichtungen. Darüber hinaus zeigt sich, dass Frauen auch nach Kontrolle von Standortfaktoren mobiler sind als Männer.

Effects of Heterogeneity on Bank Efficiency Scores

No. 1,
2009
Abstract
Bank efficiency estimates often serve as a proxy of managerial skill since they quantify sub-optimal production choices. But such deviations can also be due to omitted systematic differences among banks. In this study, we examine the effects of heterogeneity on bank efficiency scores. We compare different specifications of a stochastic cost and alternative profit frontier model with a baseline specification. After conducting a specification test, we discuss heterogeneity effects on efficiency levels, ranks and the tails of the efficiency distribution. We find that heterogeneity controls influence both banks’ optimal costs and profits and their ability to be efficient. Differences in efficiency scores are important for more than only methodological reasons. First, different ways of accounting for heterogeneity result in estimates of foregone profits and additional costs that are significantly different from what we infer from our general specification. Second, banks are significantly re-ranked when their efficiency is estimated with a specification other than the preferred, general specification. Third, the general specification gives the most reliable estimates of the probability of distress, although differences to the other specifications are low.

Are there Gender-specific Preferences for Location Factors? A Grouped Conditional Logit-model of Interregional Migration Flows in Germany

IWH Discussion Papers,
No. 5,

Abstract
The article analyses the question whether women and men differ in their tastes for location factors. The question is answered by quantifying the impact of location characteristics on interregional migration flows across Germany. The analysis is based on a grouped conditional logit approach. We augment the framework by controlling for violation of the independence of irrelevant alternatives assumption and for overdispersion. As a result, we find no differences in terms of direction of impact. However, the regressions confirm gender differences in terms of intensity, particularly regarding regional wage levels and the availability of educational institutions.

A Novel Approach to Incubator Evaluations: The PROMETHEE Outranking Procedures
Michael Schwartz, Maximilian Göthner
IWH Discussion Papers,
No. 1,
2009
Abstract
Considerable public resources are devoted to the establishment and operation of business incubators (BIs), which are seen as catalysts for the promotion of entrepreneurship, innovation activities and regional development. Despite the vast amount of research that has focused on the outcomes or effectiveness of incubator initiatives and how to measure incubator performance, there is still little understanding of how to determine incubators that are more effective than others. Based on data from 410 graduate firms, this paper applies the multi-criteria outranking technique PROMETHEE (Preference Ranking Organization Method for Enrichment Evaluation) and compares the long-term effectiveness of five technology-oriented BIs in Germany. This is the first time that outranking procedures are used in incubator evaluations. In particular, we investigate whether PROMETHEE is a well-suited methodological approach for the evaluation and comparisons in the specific context of business incubation.

The Stability of Bank Efficiency Rankings when Risk Preferences and Objectives are Different
Michael Koetter
European Journal of Finance,
No. 2,
2008
Abstract
We analyze the stability of efficiency rankings of German universal banks between 1993 and 2004. First, we estimate traditional efficiency scores with stochastic cost and alternative profit frontier analysis. Then, we explicitly allow for different risk preferences and measure efficiency with a structural model based on utility maximization. Using the almost ideal demand system, we estimate input- and profit-demand functions to obtain proxies for expected return and risk. Efficiency is then measured in this risk-return space. Mean risk-return efficiency is somewhat higher than cost and considerably higher than profit efficiency (PE). More importantly, rank–order correlation between these measures are low or even negative. This suggests that best-practice institutes should not be identified on the basis of traditional efficiency measures alone. Apparently, low cost and/or PE may merely result from alternative yet efficiently chosen risk-return trade-offs.

Enhanced Cooperation in an Enlarged EU, CeGE-Discussion Paper No. 53

Abstract
The paper adresses the need for more flexibility in the integration process of the European Union after its recent eastward enlargement. Due to the increasing number of decision-makers and the increasing heterogeneity of economic structures, financial constraints, societal preferences, and political interests, European integration based on the uniformity principle is hardly feasible. In order to avoid a rank growth of integration and yet to strengthen the momentum of flexibility, so-called enhanced cooperation appears to be an appropriate instrument to be applied to the overall integration process. In this context the paper analyzes different possible developments of selected common policies in the EU if enhanced cooperation is practised by a sub-group of EU-members. Based on cluster analysis similarities and distinctions among the EU members with respect to some specific policy realms are elaborated to identify clusters, or clubs, of countries which may apply the instrument of enhanced cooperation in the specific policy fields.
