Patience and Subnational Differences in Human Capital: Regional Analysis with Facebook Interests

Decisions to invest in human capital depend on people's time preferences. This paper shows that differences in patience are closely related to substantial subnational differences in educational achievement, leading to new perspectives on longstanding within-country disparities. We use social-media data – Facebook interests – to construct novel regional measures of patience within Italy and the United ...

Exploring Integration and Migration Dynamics: The Research Potentials of a Large-Scale Longitudinal Household Study of Refugees in Germany

Forced migration has intensified in the 21st century, driven by conflicts, persecution, and political instability in regions such as the Middle East, Afghanistan, the Horn of Africa, South-East Asia, Latin America and, most recently, Ukraine. Germany has become a primary destination for refugees within the European Union and one of the largest among the OECD countries. The IAB-BAMF-SOEP Refugee Survey, ...

Baseload Power Plants Are Not Essential for Future Power Systems

The transition to decarbonized energy systems has fueled a controversial debate over the necessity of traditional ‘‘baseload’’ power. Skepticism remains regarding the reliability and economic feasibility of power systems relying mainly on cheap variable renewable energy (VRE) sources. Addressing this, the German Academies’ project ‘‘Energy Systems of the Future’’ (ESYS) analyzed the role of baseload ...

Innovation Dynamics and Technological Maturity in the Fusion Sector: An Assessment of Fusion Projects

Nuclear fusion is envisioned for near-term energy generation deployment, with projected timelines for commercial deployment of fusion expected for the 2030s. Previous research has been limited to either economic or technological maturity assessments of the sector. To address this gap, we design a novel framework that evaluates fusion projects across the most common reactor types and derives the trajectories ...

Rent Control from Ancient Rome to the Paris Commune: A Historical Context

Sector Coupling Reimagined: Synthesizing Fragmented Perspectives Into a Unified Framework

Sector coupling (SC), the integration of energy vectors and end-use sectors, is increasingly central to the net-zero transition but remains conceptually fragmented. This fragmentation causes modeling inconsistencies, hinders cross-study comparison, and undermines energy policy coordination. We address this gap through a structured mapping of existing definitions, categorizing them along three dimensions, ...

Multi-Threshold Time Series Analysis Enables Characterization of Variable Renewable Energy Droughts in Europe

Variable renewable energy droughts, so called Dunkelflaute events, emerge as a challenge for climateneutral energy systems based on variable renewables. Here we characterize European drought events for on- and offshore wind power, solar photovoltaics, and renewable technology portfolios, using 38 historic weather years and an advanced identification method. Their characteristics heavily depend on the ...

Within-Nation Variation in War Exposure and Psychological and Physical Adjustment

The Gender Gap in Fair Earnings: The Effect of Male and Female Supervisors

Research has consistently shown that lower earnings for women and higher earnings for men are generally regarded as fair by both women and men. Previous research has focused on structural factors to explain this phenomenon, but has neglected proximate relationships at work. This study examines how the supervisors’ gender relates to employees’ justice attitudes toward the earnings of men and women. ...

What Is the “Right” Geographic Market Definition?

This paper examines the “right” geographic definition of relevant markets by analyzing how excise tax pass-through varies with local competition in the retail gasoline market of a large metropolitan city. Using a natural experiment from three unanticipated and exogenous fuel tax hikes and detailed station-level price data, we show that average pass-through is invariant to the number of nearby competitors ...
