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.

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.

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.

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 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.

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.

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.

The aim of this paper is to analyze whether the formally equal qualifications acquired during a subsidized vocational education induce equal employment opportunities compared to regular vocational training. Using replacement matching on the basis of a statistical distance function, we are able to control for selection effects resulting from different personal and profession-related characteristics, and thus, to identify an unbiased effect of the public support. Besides the ‘total effect’ of support, it is of special interest if the effect is stronger for subsidized youths in external training compared to persons in workplace-related training. The analysis is based on unique and very detailed data, the Youth Panel of the Halle Centre for Social Research (zsh).

The results show that young people who successfully completed a subsidized vocational education are disadvantaged regarding their employment opportunities even when controlling for personal and profession-related influences on the employment prospects. Besides a quantitative effect, the analysis shows that the graduates of subsidized training work in slightly worse (underqualified) and worse paid jobs than the adolescents in the reference group. The comparison of both types of subsidized vocational training, however, does not confirm the expected stronger effect for youths in external vocational education compared to workplace-related training.

In den ersten Jahren nach der Vereinigung gingen die Warenausfuhren der Neuen Bundesländer mit dem Zusammenbruch des COMECON-Handels zunächst um 70% zurück. Obgleich die ostdeutschen Länder seit Mitte der 1990er Jahre durchweg höhere Exportzuwächse verzeichneten als die westdeutschen, sind ihre Exportquoten nach wie vor vergleichsweise niedrig. Während über einen langen Zeitraum hinweg die preislichen Wettbewerbsnachteile der ostdeutschen Industrie als wesentliche Ursache für deren Exportschwäche angesehen wurden, sind mittlerweile die strukturellen Defizite der Neuen Länder in den Mittelpunkt gerückt. Im vorliegenden Beitrag wird auf der Basis bilateraler Außenhandelsdaten der deutschen Bundesländer und mit Hilfe eines klassischen Gravitationsmodells gezeigt, dass letzteres die Handelsströme der Neuen Länder nicht hinreichend erklären kann. Erweitert man den Modellansatz jedoch um zusätzliche strukturelle unabhängige Variablen, können diese die im Vergleich zu Westdeutschland geringeren Exportvolumina Ostdeutschlands nahezu vollständig erklären. Demzufolge sind die kleinteilige Unternehmensstruktur und der relativ geringe Anteil des Verarbeitenden Gewerbes an der Bruttowertschöpfung wesentliche Ursachen der schwachen Exportleistung der Neuen Länder.

Diese Studie verwendet die Methode der Hausman-Taylor-2SLS Fehler-Komponenten zur Schätzung der Determinanten von Chinas Intraindustriellem

Handel (IIT) im Investitionsgütersektor mit seinen 26 Partnerländern. Sie disaggregiert IIT in horizontalen IIT (HIIT) und vertikalen IIT (VIIT). Investitionsgüter, Endprodukte und Halbfertigwaren werden separat geschätzt, um die Unterschiede des Handels zu interpretieren. Es zeigt sich, dass die wirtschaftliche Ähnlichkeit mit IIT-Halbfertigwaren signifikant negativ korreliert ist, aber bei IIT-Endprodukten keine Signifikanz besteht. Der Faktor Ausstattung weist keine Signifikanz bei der Bestimmung von IIT-Halbfertigwaren auf, obwohl er mit IIT-Endprodukten signifikant positiv korreliert ist. Wirtschaftsgröße ist sowohl mit IIT-Endprodukten als auch mit IIT-Halbfertigwaren signifikant negativ korreliert. Entfernung wirkt sich auf das Niveau von IIT-Endprodukten aus, hat aber einen geringeren Einfluss auf IIT-Halbfertigwaren. China hat im Bereich Halbfertigwaren relativ wenig intraindustriellen Handel mit ASEAN-Staaten. Da jedoch VIIT einen dominierenden Einfluss auf TIIT ausübt, bestehen keine bedeutenden Unterschiede zwischen den Schätzungsergebnissen von TIIT und VIIT.
