IntroductionEmpirical evidence on Ronald Inglehart's theory of value change shows that subsequent generations show a decline in values of physical and economic security (materialism) in favor of an increase in values of self-expression and autonomy (postmaterialism).MethodsWe investigate in a pre-registered study whether Inglehart's theory also applies to partnership, such that millennials think less ...

2D:4D Does Not Predict Economic Preferences: Evidence from a Large, Representative Sample

The digit ratio (2D:4D) is considered a proxy for testosterone exposure in utero, and there has been a recent surge of studies testing whether 2D:4D is associated with economic preferences. Although the results are not conclusive, previous studies have reported statistically significant correlations between 2D:4D and risk taking, altruism, positive reciprocity, negative reciprocity and trust. However, ...

Heteroscedastic Proxy Vector Autoregressions

In proxy vector autoregressive models, the structural shocks of interest are identified by an instrument. Although heteroscedasticity is occasionally allowed for in inference, it is typically taken for granted that the impact effects of the structural shocks are time-invariant despite the change in their variances. We develop a test for this implicit assumption and present evidence that the assumption ...

How Often Have You Felt Disadvantaged? Explaining Perceived Discrimination

Im Rahmen einer Längsschnittanalyse des sozio-oekonomischen Panels gehen wir der Frage nach, wie sich Diskriminierungswahrnehmungen von Einwanderern und ihren Nachkommen im Laufe des Integrationsprozesses verändern. Insgesamt betrachtet fühlen sich Migrantinnen und Migranten, deren Integration weiter fortgeschritten ist, seltener aufgrund ihrer Herkunft benachteiligt. Allerdings zeigen gruppenspezifische ...

Seroepidemiological Study on the Spread of SARS-CoV-2 in Germany: Study Protocol of the ‘CORONA-MONITORING bundesweit’ Study (RKI-SOEP Study)

Das Coronavirus SARS-CoV-2 hat sich in kurzer Zeit bundesweit ausgebreitet. In den Meldedaten der Gesundheitsämter zu laborbestätigten Infektionsfällen ist von einer Untererfassung des Infektionsgeschehens auszugehen, da Infektionen häufig unentdeckt bleiben, zum Beispiel weil sie symptomarm verlaufen. In seroepidemiologischen Studien kann der Bevölkerungsanteil mit durchgemachter SARS-CoV-2-Infektion ...

The Effect of Affirmative Action on Targeted and Non-Targeted Students: Evidence from Low-income priorites in Paris High Schools

Location, Location, Location: The Role of Objective Neighborhood Characteristics for Perceptions of Control

Introduction: Control beliefs can protect against age-related declines in functioning. It is unclear whether neighborhood characteristics shape how much control people perceive over their life. This article studies associations of neighborhood characteristics with control beliefs of residents of a diverse metropolitan area (Berlin, Germany). Methods: We combine self-report data about perceptions of ...

A Green COVID-19 Recovery of the EU Basic Materials Sector: Identifying Potentials, Barriers and Policy Solutions

This paper explores climate-friendly projects that could be part of the COVID-19 recovery while jump-starting the transition of the European basic materials industry. Findings from a literature review on technology options in advanced development stages for climate-friendly production, enhanced sorting, and recycling of steel, cement, aluminium, and plastics, are combined with insights from interviews ...

Erdgas und Klimaschutz

Wissenschaft und Politik diskutieren die Zukunft von Erdgas in Deutschland. Der Kohleausstieg heißt in der Praxis in fast allen Fällen Einstieg ins Erdgas. Obwohl Erdgas ebenfalls klimaschädlich ist, wird weiter fossile Gasinfrastruktur ausgebaut und subventioniert. Gleichzeitig sind Erdgasimporte zu einem Instrument der Geopolitik gegenüber Russland und den USA geworden. In...

Freedom Gas to Europe: Scenarios Analyzed Using the Global Gas Model

State-of-the-art, open access numerical modeling of imperfectly competitive energy markets offers a sound and transparent way to address topical research questions in energy and commodity markets. We use an open access equilibrium model, the Global Gas Model (GGM), and sector-specific, politically motivated scenarios to investigate the prospects for sales of liquefied natural gas (LNG) from the U.S. ...
