A Linear Reduced-Order Model for the Activated Sludge Process for the Integration into a Mixed-Integer Linear Energy System Optimisation Model

Conventional wastewater treatment plants consume significant amounts of electricity. The constant aeration of the wastewater in order to foster the growth of microorganisms or the pumping of wastewater are two examples for energy-intensive processes within a plant. Case studies have shown that switching off blowers and inlet pumps for a certain period of time is possible without a loss in water quality. ...

Adding Household Surveys to the Behavioral Economics Toolbox: Insights from the SOEP Innovation Sample

While laboratory and field experiments are the major items in the toolbox of behavioral economists, household panel studies can complement them and expand their research potential. We introduce the German Socio-Economic Panel’s Innovation Sample (SOEP-IS), which offers researchers detailed panel data and the possibility to collect personalized experimental and survey data for free. We discuss what ...

German Financial State Aid during Covid-19 Pandemic: Higher Impact among Digitalized Self-Employed

The EU Sustainable Finance Taxonomy and Its Contribution to Climate Neutrality

The EU Taxonomy is the first standardised and comprehensive classification system for sustainable economic activities. It covers activities responsible for up to 80% of EU greenhouse gas emissions and may play an important role in channelling investments into low-carbon technologies by helping investors to make informed decisions. However, especially in transition sectors much depends on the stringency ...

Exploring the Interdependence of Climate, Finance, Energy, and Geopolitics: A Conceptual Framework for Systemic Risks Amidst Multiple Crises

Navigating the transition toward a zero-emission and just future amidst multiple crises requires a nuanced understanding of potential hindrances to investments and energy transitions. As current approaches hardly consider the big picture of interacting crises, this study offers a framework to analyze the dynamics and risk channels between 1) the climate crisis, 2) financial (in)stability, 3) the geopolitical ...

Effect of Area-Level Socioeconomic Deprivation on Mental and Physical Health: A Longitudinal Natural Experiment among Refugees in Germany

Existing studies on contextual health effects struggle to account for compositional bias, limiting causal interpretation. We use refugee dispersal in Germany as a natural experiment to study the effect of area-level socioeconomic deprivation on mental and physical health, while considering the potential mediating role of neighbourhood characteristics. Refugees subject to dispersal (n = 1466) are selected ...

Einsamkeit in Deutschland – Prävalenz, Entwicklung über die Zeit und regionale Unterschiede

Hintergrund Einsamkeit ist weitverbreitet und hat negative Folgen für die Gesundheit. Diese Studie soll die Fragen beantworten: (1) wie viele Menschen in Deutschland hocheinsam sind, (2) wie sich die Einsamkeit in Deutschland über die Zeit – insbesondere im Hinblick auf die Covid-19-Pandemie – veränderte und (3) welche regionalen Unterschiede es in der Einsamkeit in Deutschland gibt.MethodenDie vorliegende ...

The Intergenerational Transmission of Risk and Trust Attitudes: Replicating and Extending “Dohmen, Falk, Huffman and Sunde 2012” Using Genetically Informed Twin Data

This replication revisits an influential contribution on the intergenerational transmission of risk and trust attitudes, which, based on data from the German Socioeconomic Panel (GSOEP), reveals a positive correlation between parents' and children's attitudes. The authors of the original study argue that socialization in the family is important in the transmission process. The replication is motivated ...

Assessing the Social and Environmental Impacts of Critical Mineral Supply Chains for the Energy Transition in Europe

Advanced technologies are inherently dependent on critical minerals and their related metals. The mining extraction of these critical minerals leads to significant social and environmental impacts that extend beyond the regions where those advanced technologies are ultimately used. This study explores the global socio-environmental challenges arising from the European Climate Law's aim for net-zero ...

Social Security and Retirement around the World: Lessons from a Long-Term Collaboration

Declining labor force participation of older men throughout the 20th century and recent increases in participation have generated substantial interest in understanding the effect of public pensions on retirement. The National Bureau of Economic Research's International Social Security (ISS) Project, a long-term collaboration among researchers in a dozen developed countries, has explored this and related ...
