Mexico and U.S. Power Systems under Variations in Natural Gas Prices

This study examines the impact of natural gas prices on the power systems of Mexico and the United States. For this, we develop an integrated modeling framework by soft linking three different techno-economic bottom-up models of the power and energy systems, one partial equilibrium model of the natural gas sector, and a partial equilibrium model of the Mexican energy sector. Our results show several ...

Aktuelle Reformvorschläge zum Einkommensteuertarif: Mittelschichten entlasten, hohe Einkommen belasten

Der aktuelle Einkommensteuertarif belastet Mittelschichten und Besserverdienende relativ stark durch den schnellen Anstieg der Progression. Entlastungen durch eine Anhebung des Grundfreibetrags oder eine Abmagerung des Mittelstandsbauchs führen leicht zu Steuerausfällen von höheren zweistelligen Milliardenbeträgen im Jahr. Erhöhungen der Spitzensteuersätze wirken dem entgegen, allerdings sind die Aufkommenspotenziale ...

Time Spent on School-Related Activities at Home During the Pandemic: A Longitudinal Analysis of Social Group Inequality among Secondary School Students

Substantial educational inequalities have been documented in Germany for decades. In this article, we examine whether educational inequalities among children have increased or remained the same since the school closures of spring 2020 due to the COVID-19 pandemic. Our perspective is longitudinal: We compare the amount of time children in secondary schools spent on school-related activities at home ...

The Intergenerational Transmission of Gender Norms: Why and How Adolescent Males with Working Mothers Matter for Female Labour Market Outcomes

Social norms are put forward as a prominent explanation for the changing labour supply decisions of women. This paper studies the intergenerational transmission of these norms, examining how they affect subsequent female labour supply decisions, taking into account not only the early socialization of women but also that of their partner. Using large representative panel data sets from West Germany, ...

Longitudinal Coupling of Momentary Stress Reactivity and Trait Neuroticism: Specificity of States, Traits, and Age Period

Personality traits like neuroticism show both continuity and change across adolescence and adulthood, with most pronounced changes occurring in young adulthood. It has been assumed, but insufficiently examined, that trait changes occur gradually over the years through the accumulation of daily experiences. The current longitudinal measurement burst study examined (a) how changes in average momentary ...

Die Studie untersucht, ob Unterschiede in der Nutzung von Gesundheitsinformationen und psychologischer Online-Beratung auf Basis soziodemografischer ...

The Impact of Carbon Disclosure Mandates on Emissions and Financial Operating Performance

We examine the impact of a disclosure mandate for greenhouse gas emissions on firms’ subsequent emission levels and financial operating performance. For UK-incorporated listed firms a carbon disclosure mandate was adopted in 2013. Our difference-in-differences design shows that firms affected by the mandate reduced their emissions by about 8% relative to a control group of European firms. At the same ...

SOEP-RV: Linking German Socio-Economic Panel Data to Pension Records

The aim of the project SOEP-RV is to link data from participants in the German Socio-Economic Panel (SOEP) survey to their individual Deutsche Rentenversicherung (German Pension Insurance) records. For all SOEP respondents who give explicit consent to record linkage, SOEP-RV creates a linked dataset that combines the comprehensive multi-topic SOEP data with detailed cross-sectional and longitudinal ...

Inspections and Compliance: Enforcement of the Minimum-Wage Law

This paper is the first to empirically study the relationship between spatial distributions oflabor market inspections and noncompliance with Germany’s minimum-wage law. Combiningnovel administrative data with large-scale longitudinal survey data, we documentthat the inspection probability is higher in regions with higher noncompliance. This impliesrisk-based allocation of the inspection efforts and, ...

COVID-19 Associated Contact Restrictions in Germany: Marked Decline in Children’s Outpatient Visits for Infectious Diseases without Increasing Visits for Mental Health Disorders

Children have a low risk for severe COVID-19 infections, but indirect consequences of the pandemic may affect their health. We evaluated nationwide data on children’s outpatient visits before and during the first wave of the COVID-19 pandemic in Germany. Data from the National Association of Statutory Health Insurance Physicians for all children with statutory health insurance and at least one physician’s ...

Fertility as a Driver of Maternal Employment

Based on findings from high-income countries, typically economists hypothesize that having more children unambiguously decreases the time mothers spend in the labor market. Few studies on lower-income countries, in which low household wealth, informal child care, and informal employment opportunities prevail, find mixed results. Using Mexican census data, I do not find evidence for negative employment ...

Bundesbeteiligung an den Kosten der Unterkunft - ein "pragmatischer" Transfer

Die Beteiligung des Bundes an den Kosten der Unterbringung und Heizung (KdU) erfolgt seit der Einführung des SGB II 2005 mit dem Ziel, die Kommunen finanziell zu entlasten. Seitdem wurde die Bundesbeteiligung in Höhe, Struktur, Berechnung und Zweck beständig verändert. Der Beitrag zeigt, wie sich dieser Transfer im Zeitablauf entwickelt hat, aus welchen Komponenten er heute besteht und welche Kritikpunkte ...

Leisure Activities as a Driver of Personality Development? A Random-Intercept Cross-lagged Panel Model across 13 Years in Adulthood

Repeated experiences and activities drive personality development. Leisure activities are among the daily routines that may elicit personality change. Yet despite the important role they play in daily life, little is known about their prospective effects on personality traits and vice versa. The objective of this study was to examine the extent to which within-person changes in leisure activities lead ...

Discounting Behavior in Problem Gambling

Problem gamblers discount delayed rewards more rapidly than do non-gambling controls. Understanding this impulsivity is important for developing treatment options. In this article, we seek to make two contributions: First, we ask which of the currently debated economic models of intertemporal choice (exponential versus hyperbolic versus quasi-hyperbolic) provides the best description of gamblers’ discounting ...

Long-run Expectations of Households

The rational expectations assumption, e.g. in life-cycle models and portfolio-choice models, prescribes that all actions are in line with a well-structured and unbiased system of expectations. In reality, justification and identification of expectations are nontrivial, and we lack empirical evidence especially for the long run. This paper starts to fill this gap and elicits short-run and long-run expectations ...

Urban Green Is More than the Absence of City: Structural and Functional Neural Basis of Urbanicity and Green Space in the Neighbourhood of Older Adults

The relationship between urbanization, the brain, and human mental health is subject to intensive debate in the current scientific literature. Particularly, since mood and anxiety disorders as well as schizophrenia are known to be more frequent in urban compared to rural regions.Here, we investigated the association between cerebral signatures, mental health and land use indicators (Urban Fabric and ...

Extending the Kitagawa–Oaxaca–Blinder Decomposition Approach to Panel Data

The Kitagawa–Oaxaca–Blinder decomposition approach has been widely used to attribute group-level differences in an outcome to differences in endowment, coefficients, and their interactions. The method has been implemented for Stata in the popular oaxaca command for cross-sectional analyses. In recent decades, however, research questions have been more often focused on the decomposition of group-based ...
