Abstract
Das Institut für Wirtschaftsforschung Halle (IWH) veranstaltet unter Federführung der Forschungsabteilung Stadtökonomik alle zwei Jahre das „Hallesche Kolloquium zur kommunalen Wirtschaft“. Vor dem Hintergrund der kommunalen Gebietsreformen in Ostdeutschland befasste sich die Veranstaltung am 24. und 25. November 2011 mit der Frage, ob insbesondere mit Bezug auf den Kommunalbereich „bigger“ notwendigerweise auch „better“ (z. B. im Sinne einer möglichst kostengünstigen Versorgung mit öffentlichen Leistungen) bedeuten muss.
Die Konferenz richtete sich dabei sowohl an Wissenschaftler als auch an Praktiker aus Politik und Verwaltung. Im Mittelpunkt standen dabei wissenschaftliche Erkenntnisse zur Effizienz des öffentlichen Sektors auf verschiedenen Ebenen. Beleuchtet wurde dieses Thema nicht nur aus der volkswirtschaftlichen, sondern auch aus der rechts- und verwaltungswissenschaftlichen Perspektive. Nach den Fachvorträgen aus den genannten Bereichen bildete eine Podiumsdiskussion mit Vertretern aus Kommunalpolitik, Kommunalverbänden und Landesverwaltung
den Abschluss der Konferenz. Insgesamt zeigte die Veranstaltung auf, dass Größe nicht alles ist bei der Gestaltung künftiger Kommunalstrukturen und Gebietsreformen alles andere als ein Allheilmittel bei mangelnder Leistungsfähigkeit (z. B. Finanzschwäche) der Kommunen sind.

Fiscal Spending Multiplier Calculations Based on Input-Output Tables? An Application to EU Member States

Intervention. European Journal of Economics and Economic Policies,
No. 1,
2012
Abstract
Fiscal spending multiplier calculations have attracted considerable attention in the aftermath of the global financial crisis. Much of the current literature is based on VAR estimation methods and DSGE models. In line with the Keynesian literature we argue that many of these models probably underestimate the fiscal spending multiplier in recessions. The income-expenditure model of the fiscal spending multiplier can be seen as a good approximation under these circumstances. In its conventional form this model suffers from an underestimation of the multiplier due to an overestimation of the import intake of domestic absorption. In this article we apply input-output calculus to solve this problem. Multipliers thus derived are comparably high, ranging between 1.4 and 1.8 for many member states of the European Union. GDP drops due to budget consolidation might therefore be substantial in times of crisis.

Extreme Dependence with Asymmetric Thresholds: Evidence for the European Monetary Union
Stefan Eichler, R. Herrera
Journal of Banking and Finance,
No. 11,
2011
Abstract
Existing papers on extreme dependence use symmetrical thresholds to define simultaneous stock market booms or crashes such as the joint occurrence of the upper or lower one percent return quantile in both stock markets. We show that the probability of the joint occurrence of extreme stock returns may be higher for asymmetric thresholds than for symmetric thresholds. We propose a non-parametric measure of extreme dependence which allows capturing extreme events for different thresholds and can be used to compute different types of extreme dependence. We find that extreme dependence among the stock markets of ten initial EMU member countries, the United Kingdom, and the United States is largely asymmetrical in the pre-EMU period (1989–1998) and largely symmetrical in the EMU period (1999–2010). Our findings suggest that ignoring the possibility of asymmetric extreme dependence may lead to an underestimation of the probability of co-booms and co-crashes.

Macroeconomic Imbalances as Indicators for Debt Crises in Europe
Tobias Knedlik, Gregor von Schweinitz
Wirtschaft im Wandel,
No. 10,
2011
Abstract
Die Schulden- und Vertrauenskrise in Europa hat eine intensive Diskussion über die makroökonomische Koordinierung ausgelöst. Die bestehenden Institutionen, darunter auch der Stabilitäts- und Wachstumspakt, haben sich als Krisenpräventions- und Krisenmanagementinstrumente nicht bewährt. Ein Vorschlag in der gegenwärtigen Debatte lautet, anhand geeigneter Frühindikatoren eine regelmäßige und systematische makroökonomische
Überwachung vorzunehmen, um sich anbahnende Krisen früh erkennen und darauf reagieren zu können. Dieser Beitrag stellt die Prognosegüte von vier vorgeschlagenen Indikatorensets vergleichend dar, wobei sowohl die Güte
von Einzelindikatoren als auch die Güte aggregierter Gesamtindikatoren betrachtet werden. Die verschiedenen Einzelindikatoren weisen eine sehr unterschiedliche Prognosequalität auf, wobei sich neben dem Staatsdefizit
besonders die Arbeitsmarktindikatoren, die private Verschuldung und der Leistungsbilanzsaldo durch eine hohe Prognosegüte auszeichnen. Unter den Gesamtindikatoren schneiden besonders jene gut ab, die sowohl viele unterschiedliche als auch besonders gute Einzelindikatoren beinhalten. Deshalb wird für den Einsatz eines breit basierten Gesamtindikators bei der makroökonomischen Überwachung plädiert. Dieser sollte zudem aus gleichgewichteten Einzelindikatoren zusammengesetzt sein, um der Tatsache Rechnung zu tragen, dass die Ursachen künftiger Krisen vorab nicht bekannt sind.

International Fragmentation of Production and the Labour Input into Germany’s Exports – An Input-Output-analysis
Hans-Ulrich Brautzsch, Udo Ludwig
IWH Discussion Papers,
No. 14,
2011
Abstract
The import penetration of exports has become a topic of public debate, particularly in the context of Germany’s position as one of the world’s leading exporters. The growth in the volume of intermediate products purchased from abroad for subsequent processing into export goods in Germany seems to be undermining the importance of exports as a driver of domestic production and employment. The gains that arise from an increase in exports seem to have been offset by the losses caused by the crowding out of local production by imports. Empirical evidence on the impact of this international integration of the goods market on the German labour market is ambiguous. Short-term negative effects on employment are claimed to be offset by the long-term benefit that the jobs lost in the short run will eventually be replaced by higher-skilled jobs with better
perspectives. Against this background, the following hypothesis is tested empirically: Germany is poor in natural resources, but rich in skilled labour. In line with the Heckscher- Ohlin theory, Germany should therefore specialize in the production of export goods and services that are relatively intensive in these factors and should import those goods and services that are relatively intensive in unskilled labour. The empirical part of the paper deals with the extent of the German export penetration by imports. At first, it analyses by what ways imports are affecting the exports directly and indirectly and shows the consequences of import penetration of exports for the national output and employment. Secondly, consequences for employment are split in different skill types of labour. These issues are discussed with the standard open static inputoutput- model. The data base is a time series of official input-output tables. The employment effects for Germany divided by skill types of labour are investigated using skill matrices generated by the authors.

Macroeconomic Imbalances as Indicators for Debt Crises in Europe
Tobias Knedlik, Gregor von Schweinitz
Abstract
European authorities and scholars published proposals on which indicators of macroeconomic imbalances might be used to uncover risks for the sustainability of public debt in the European Union. We test the ability of four proposed sets of indicators to send early-warnings of debt crises using a signals approach for the study of indicators and the construction of composite indicators. We find that a broad composite indicator has the highest predictive power. This fact still holds true if equal weights are used for the construction of the composite indicator in order to reflect the uncertainty about the origin of future crises.

Exploring the Economic Convergence in the EU New Member States by Using Nonparametric Models
Monica Raileanu Szeles
IWH Discussion Papers,
No. 2,
2011
Abstract
This paper analyzes the process of real economic convergence in the New Member States (NMS) bein g formerly centrally planned economies, using nonparametric methods instead of conventional parametric measurement tools like beta and sigma models. This methodological framework allows the examining of the relative income distribution in different periods of time, the number of modes of the density distribution, the existence of “convergence clubs” in the distribution and the hypothesis of convergence at a single point in time. The modality tests (e.g. the ASH-WARPing procedure) and stochastic kernel are nonparametric techniques used in the empirical part of the study to examine the income distribution in the NMS area. Additionally, random effects panel regressions are used, but only for comparison reasons. The main findings of the paper are the bimodality of the income density distribution over time and across countries, and the presence of convergence clubs in the income distribution from 1995 to 2008. The findings suggest a lack of absolute convergence in the long term (1995-2008) and also when looking only from 2003 onwards. The paper concludes that, in comparison with the parametrical approach, the nonparametric one gives a deeper, real and richer perspective on the process of real convergence in the NMS area.

Fiscal Spending Multiplier Calculations based on Input-Output Tables – with an Application to EU Members
Toralf Pusch, A. Rannberg
Abstract
Fiscal spending multiplier calculations have been revived in the aftermath of the
global financial crisis. Much of the current literature is based on VAR estimation
methods and DSGE models. The aim of this paper is not a further deepening of
this literature but rather to implement a calculation method of multipliers which is
suitable for open economies like EU member states. To this end, Input-Output tables are used as by this means the import intake of domestic demand components can be isolated in order to get an appropriate base for the calculation of the relevant import quotas. The difference of this method is substantial – on average the calculated multipliers are 15% higher than the conventional GDP fiscal spending multiplier for EU members. Multipliers for specific spending categories are comparably high, ranging between 1.4 and 1.8 for many members of the EU. GDP drops due to budget consolidation might therefore be substantial if monetary policy is not able to react in an expansionary manner.

Has the Euro Increased International Price Elasticities?
Oliver Holtemöller, Götz Zeddies
IWH Discussion Papers,
No. 18,
2010
published in: Empirica
Abstract
This paper analyzes the role of common data problems when identifying structural breaks in small samples. Most notably, we survey small sample properties of the most commonly applied endogenous break tests developed by Brown, Durbin, and Evans (1975) and Zeileis (2004), Nyblom (1989) and Hansen (1992), and Andrews, Lee, and Ploberger (1996). Power and size properties are derived using Monte Carlo simulations. Results emphasize that mostly the CUSUM type tests are affected by the presence of heteroscedasticity, whereas the individual parameter Nyblom test and AvgLM test are proved to be highly robust. However, each test is significantly affected by leptokurtosis. Contrarily to other tests, where skewness is far more problematic than kurtosis, it has no additional effect for any of the endogenous break tests we analyze. Concerning overall robustness the Nyblom test performs best, while being almost on par to more recently developed tests in terms of power.

Is there a Superior Distance Function for Matching in Small Samples?
Eva Dettmann, Claudia Becker, Christian Schmeißer
Abstract
The study contributes to the development of ’standards’ for the application of matching algorithms in empirical evaluation studies. The focus is on the first step of the matching procedure, the choice of an appropriate distance function. Supplementary o most former studies, the simulation is strongly based on empirical evaluation ituations. This reality orientation induces the focus on small samples. Furthermore, ariables with different scale levels must be considered explicitly in the matching rocess. The choice of the analysed distance functions is determined by the results of former theoretical studies and recommendations in the empirical literature. Thus, in the simulation, two balancing scores (the propensity score and the index score) and the Mahalanobis distance are considered. Additionally, aggregated statistical distance functions not yet used for empirical evaluation are included. The matching outcomes are compared using non-parametrical scale-specific tests for identical distributions of the characteristics in the treatment and the control groups. The simulation results show that, in small samples, aggregated statistical distance functions are the better
choice for summarising similarities in differently scaled variables compared to the
commonly used measures.
