Die Begrenzung systemischer Risiken ist essentieller Bestandteil der neuen internationalen Finanzmarktordnung. Dabei galt es nicht nur die Verflechtung der Banken untereinander, sondern auch die Verbindung zwischen den Staatsfinanzen und der Solvenz der nationalen Bankensysteme (dem sog. Risikoverbund zwischen Staat und Banken) zu durchbrechen. Der Beitrag beleuchtet die Entwicklung der Forderungen gegenüber Staaten in den Bankbilanzen der Euroländer und des Eurosystems im Zeitverlauf sowie den daraus erwachsenden Risiken für die Finanzstabilität. Hierzu werden die Determinanten des Risikoverbunds theoretisch wie empirisch analysiert. Die fiskalische Kapazität der Eurostaaten wird anhand verschiedener Faktoren wie der Verschuldungsquote, dem Leistungsbilanzsaldo und der Kredit-BIP Lücke aufgezeigt; anschließend werden die Strukturen der Bankensysteme im Euroraum untersucht. Im Einzelnen werden die private und staatliche Gesamtverschuldung, die konsolidierte Bankenbilanzsumme und die darin enthaltenen Verbindlichkeiten sowie der Anteil des Bankensektors an der Bruttowertschöpfung in Relation zur Wirtschaftsleistung betrachtet. Außerdem finden NPE-Bestände in den Bankbilanzen sowie die Renditen der emittierten Staatsanleihen und damit in Verbindung stehenden CDS-Spreads Betrachtung. Zusätzlich werden die Konzentration, der Verschuldungsgrad, Liquiditätsziffern sowie länderspezifische Unterschiede in Art und Fristigkeit der Refinanzierung der Bankensektoren abgebildet. Auf Basis der empirischen Befunde werden im Hinblick auf die wechselseitigen Ansteckungseffekte zwischen Banken und Staaten Implikationen für die Finanzmarktregulierung diskutiert.
While inequality of opportunity (IOp) in earnings is well studied, the literature on IOp in individual net wealth is scarce to non-existent. This is problematic because both theoretical and empirical evidence show that the position in the wealth and income distribution can significantly diverge.We measure ex-ante IOp in net wealth for Germany using data from the Socio-Economic Panel (SOEP). Ex-ante IOp is defined as the contribution of circumstances to the inequality in net wealth before effort is exerted. The SOEP allows for a direct mapping from individual circumstances to individual net wealth and for a detailed decomposition of net wealth inequality into a variety of circumstances; among them childhood background, intergenerational transfers, and regional characteristics. The ratio of inequality of opportunity to total inequality is stable from 2002 to 2019. This is in sharp contrast to labor earnings, where ex-ante IOp is declining over time. Our estimates suggest that about 62% of the inequality in net wealth is due to circumstances. The most important circumstances are intergenerational transfers, parental occupation, and the region of birth. In contrast, gender and individuals’ own education are the most important circumstances for earnings.
National Action Plans (NAPs) have been increas-ingly adopted world-wide after the Vienna Dec-laration in 1993, where it was urged to consider the improvement and promotion of Human Rights. In this paper, we discuss their usefulness and success by analysing the challenges present-ed during NAP processes as well as the benefits this set of actions entails: The challenges for their implementation outweigh its actual benefits. Nevertheless, NAPs have great potential. Based on new research, we elaborate a set of recom-mendations for improving the design and imple-mentation of national action planning. In order to effectively bring NAP into practice, we consider it crucial to plan and analyse every state local circumstances in detail. The latter is important, since the implementation of a concrete set of actions is intended to directly transform and improve the local living conditions of the people. In a long-term perspective, we defend the benefit of NAP’s implementation for complying obliga-tions set up by HR treaties.
Under Brazil's ex-president Bolsonaro, deforestation of the Amazon increased dramatically. An Austrian NGO filed a complaint to the Prosecutor of the International Criminal Court (ICC) against Bolsonaro in October 2021, accusing him of crimes against humanity against the backdrop of his involvement in environmental destruction. This paper deals with the question of whether this initi-ative constitutes a promising means of juridification to mitigate conflicts revolving around mass deforestation in Brazil. It thematizes attempts to juridify environmental destruction in international criminal law and examines the Climate Fund Case at the Brazilian Supreme Court. Finally, emerging problems and arguments in favour of starting preliminary examinations at the ICC against Bolsonaro are illuminated. This paper provides arguments as to why the initiative might be a promising undertaking, even though it is unlikely that Bolsonaro will be arrested.
Gruppierung von Daten
(2022)
Dieser Beitrag beinhaltet einen Vergleich zwischen den Methoden der Topologischen Datenanalyse (TDA) und statistischen Clusterverfahren bei der Gruppierung von Daten. Es werden Gemeinsamkeiten und Unterschiede bei der Bildung der Cluster und Zuordnung der statistischen Einheiten identifiziert. Hierzu werden zwei empirische Datensätze aus der Biologie und Medizin herangezogen.
Zusammengefasst haben sich die Verfahren der TDA als ein praktikables Werkzeug bei der Gruppierung von Objekten erwiesen. Vor allem mit dem Mapper-Algorithmus konnten adäquate Cluster erkannt werden. Beim Iris Flower-Datensatz hat die TDA ähnliche Ergebnisse wie die Clusteranalyse erzielt. Der Heart Disease-Datensatz war schwieriger zu behandeln. Die genutzten clusteranalytischen Verfahren waren nicht geeignet, die beiden Gruppen von Patienten korrekt zu identifizieren. Im Vergleich zu den Standardverfahren der Clusteranalyse zeigte sich eine leichte Überlegenheit der topologischen Verfahren.
Untersucht werden die von BulwienGesa erhobenen und aufbereiteten jahresdurchschnittlichen Mieten von Wohnungen und die Relation des Wiederverkaufswertes von Eigentumswohnungen zu den Wohnungsmieten (Preis-Miet-Relation) in 401 kreisfreien Städten und Landkreisen für die Jahre 2004–2017. Dabei zeigt sich bei den Wohnungsmieten eine Zunahme der regionalen Streuung im Zeitverlauf vor allem in der auf die Finanzkrise 2007–2009 folgenden Zeit. Bei der Preis-Miet-Relation nimmt die Streuung im Zeitverlauf ab 2010 ebenfalls zu. Im Durchschnitt der Regionen (Landkreise und kreisfreie Städte) steigen über den gesamten Zeitabschnitt die Mieten und in der überwiegenden Zahl der Regionen auch die Preis-Miet-Relation (allerdings erst ab 2010); sie entwickeln sich aber regional stark unterschiedlich. Dies führt auch zur Zunahme der Variationskoeffizienten, also der relativen Streuung der regionalen Mieten und – ab 2010 – auch der regionalen Preis-Miet-Relationen.
Dies deutet auf eine Zunahme der regionalen Disparitäten in der Bundesrepublik Deutschland hin. Besondere Divergenzen zeigen sich zwischen den alten und den neuen Bundesländern, wie auch zwischen prosperierenden kreisfreien Städten und deren Umland und ökonomisch schwächeren Städten und Landkreisen.
Starting in 2009, the German state of Saxony distributed sports club membership vouchers among all 33,000 third graders in the state. The policy’s objective was to encourage them to develop a long-term habit of exercising. In 2018, we carried out a large register-based survey among several cohorts in Saxony and two neighboring states. Our difference-in-differences estimations show that, even after a decade, awareness of the voucher program was significantly higher in the treatment group. We also find that youth received and redeemed the vouchers. However, we do not find significant short- or long-term effects on sports club membership, physical activity, overweightness, or motor skills.
Against a background of increasing violence against non-natives, we estimate the effect of hate crime on refugees’ mental health in Germany. For this purpose, we combine two datasets: administrative records on xenophobic crime against refugee shelters by the Federal Criminal Office and the IAB-BAMF-SOEP Survey of Refugees. We apply a regression discontinuity in time design to estimate the effect of interest. Our results indicate that hate crime has a substantial negative effect on several mental health indicators, including the Mental Component Summary score and the Patient Health Questionnaire-4 score. The effects are stronger for refugees with closer geographic proximity to the focal hate crime and refugees with low country-specific human capital. While the estimated effect is only transitory, we argue that negative mental health shocks during the critical period after arrival have important long-term consequences. Keywords: Mental health, hate crime, migration, refugees, human capital.
This paper evaluates the construction of the rights of human rights defenders within international law and its shortcomings in protecting women. Human rights defenders have historically been defined on the basis of their actions as defenders. However, as Marxist-feminist scholar Silvia Federici contends, women are inherently politicised and, moreover, face obstacles to political action which are invisible to and untouchable by the law. Labour rights set an example of handling such a disadvantaged political position by placing vital importance on workers’ right to association and collective action. The paper closes with the suggestion that transposing this construction of rights to women would better protect women as human rights defenders while emphasising their capacity for self-determination in their political actions.
Using quantile regression methods, this paper analyses the gender wage gap across the wage distribution and over time (1990–2014), while controlling for changing sample selection into full-time employment. Our findings show that the selection-corrected gender wage gap is much larger than the one observed in the data, which is mainly due to large positive selection of women into full-time employment. However, we show that selection-corrected wages of male and female workers at the lower half of the distribution have moderately converged over time. The reason for this development have been changes in the composition of the male full-time employment force over time, which in spite of the rather constant male full-time employment rate, have given place to a small but rising selection bias in male observed wages. In the upper half of the wage distribution, however, neither the observed nor the selection-corrected gender wage gap has narrowed over time.
