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

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 ...

Fostering Sustainable and Resilient Coastal Communities Through Combining Nature-Based Solutions and Empowerment Tools: A Review

Nature-based Solutions (NbS) have proven successful to address major coastal environmental challenges. Participatory approaches to NbS planning, design and implementation are increasing, yet community empowerment remains an underexplored aspect of NbS. This paper aims to assess the current state of knowledge on the contribution of community empowerment in NbS approaches to address coastal challenges ...

Beyond Overall Income Inequality: Racial Income Gaps and Health Disparities

In this paper, we combine Census data with death records to examine the relationship between income inequality and race-specific mortality across 5,565 municipalities in Brazil. We find that overall income inequality is strongly associated with Non-White mortality but not with White mortality. To understand this disparity, we decompose the Gini coefficient and find that the racial income gap accounts ...

Public Communication and Collusion: New Screening Tools for Competition Authorities

Competition authorities increasingly rely on economic screening tools to identify markets where firms deviate from competitive norms. Traditional screening methods assume that collusion occurs through secret agreements. However, recent research highlights that firms can use public announcements to coordinate decisions, thereby reducing competition while avoiding detection.We propose a novel approach ...

Unintended Consequences of COVID-19 Public Health and Social Measures in Camps and Camp-Like Settings: A Systematic Review and Conceptual Analysis

Objectives: This study examines unintended consequences (UIC) of public health and social measures (PHSM) in camps and camp-like settings and assesses the pathways through which these UIC arise. Methods: We conducted a systematic review and conceptual analysis of UIC from PHSM aimed at preventing SARS-CoV-2 spread in these settings. PHSM were classified using the WHO taxonomy and the CONSEQUENT framework ...

Heterogeneity in Gender Differences in Self-Reported Political Preferences, Trust, and Well-Being across 39 European Countries

Previous research suggests that women tend to self-report higher life satisfaction and happiness, lower health status and trust, and more left-leaning political preferences than men. We revisit the gender gap in these outcome variables using random-effects meta-analysis, aggregating data across 39 countries surveyed in the European Social Survey (n ≈ 500,000). Measured in Cohen’s d units, women, on ...

The German Artificial Intelligence Experience and Attitude Survey (AIEAS): A Brief Measure for Socio-Economic Panel Studies

Despite the profound impact of artificial intelligence (AI) in diverse contexts, large-scale socio-economic panel studies have rarely addressed the use and evaluation of AI for individual respondents. Therefore, the Artificial Intelligence Experience and Attitude Survey (AIEAS) is introduced to measure awareness, experience, attitude valence, and usage intention regarding AI in the work, healthcare, ...

From Low Emission Zone to Academic Track: Environmental Policy Effects on Educational Achievement in Elementary School

Do long-term improvements in air quality influence children’s educational outcomes? This paper investigates the impact of Low Emission Zones (LEZs), which restrict access to designated areas for emission-intensive vehicles, on the educational achievement of elementary school students in Germany. Using school-level data from North Rhine-Westphalia, Germany’s most populous state, we exploit the staggered ...

Worst First: Thermal Retrofits, Carbon Prices, and Inequality

The energy price crisis following Russia’s invasion of Ukraine exposed the heightened vulnerability of low-income households to rising heating costs, particularly those in energy-inefficient buildings. Using data from the German Socio-Economic Panel (SOEP), this study examines the distributional impact of heating costs across income deciles and evaluates the effectiveness of policy interventions. We ...

System Justification and Democracy: Is Liberal Democracy Part of the Status Quo?

How Do Individuals Interact with the Police? Validation of a Scale of Motivational Postures toward the Police in Spanish

This article addressed the critical issue of citizens’ attitudes toward law enforcement, focusing on motivational postures toward the police (i.e., the psychological dispositions that individuals maintain toward the police). The study contributes by providing the first validated motivational postures scale toward the police in Spanish. It responds to a gap in research on motivational postures within ...

Committed to Flexible Fiscal Rules

We study the implications of fiscal rules for macroeconomic stabilization when countries are hit by adverse exogenous shocks. Exploiting the unpredictability of natural disasters, we document that economies with a fiscal rule absorb these shocks better than those without: the responses of GDP and private demand are significantly higher. This difference is coupled with more expansionary fiscal policy ...

Lifting Women Up: Gender Quotas and the Advancement of Women on Corporate Boards

Research Question/Issue: The introduction of gender quotas on corporate boards can disrupt the status quo, resulting in externalities that affect women's advancement within the company. This study investigates whether boardroom quotas contribute to promoting women further up the corporate ladder and facilitate access to a broader spectrum of positions. Research Findings/Insights: Using legislative ...

El trabajo por cuenta propia como repertorio de acción: recuperando el tiempo propio en Santiago de Chile

This article uses a longitudinal qualitative methodology to explore the increased appreciation of independent work in Santiago, Chile, following the 2019 protests and during the COVID-19 pandemic. Findings suggest that workers in precarious conditions actively seek autonomy and control over their time. We argue that self-employment should be understood as a cultural repertoire of action and a resilience ...
