Abstract
Using survey experiments in the United States and Germany with about 12,000 participants, we study perceptions of socioeconomic inequality in life expectancy and policy demand. Respondents overestimate the rich-poor gap in both countries, judging the life expectancy of the rich roughly accurately but placing that of the poor well below its true level. These misperceptions vary little with political orientation or other characteristics. Correcting them shifts concern but leaves policy demand largely unchanged across general, specific, and real-stakes measures. Instead, demand divides politically, sharply in the United States and much less in Germany, consistent with views about the role of government rather than the inequality itself shaping policy demand.

Time To Close the Socioeconomic Gap in Access to Childcare
Henning Hermes, Philipp Lergetporer, Frauke Peter, Simon Wiederhold
Nature Human Behaviour,
Vol. 10 (7),

Abstract
Socioeconomic inequalities shape who accesses early childcare, even in countries that claim universal provision. This entrenched inequality limits child development, women’s employment and gender equality — but governments have clear tools to close the gap.

The Health Costs of Losing Political Representation: Evidence From U.S. Presidential Elections
Sris Chatterjee, Iftekhar Hasan, Stefano Manfredonia

Vol. 20 (10),
2025
Abstract
We investigate whether a change in political leadership affects health outcomes. To do so, we exploit turnover elections that move partisan individuals into and out of alignment with the party of the President. We document that the lack of political alignment has a negative, immediate, and long-lasting effect on health. We do not find any evidence that our results can be explained by other confounding trends or by changes in economic outcomes or other economic policies. Further results suggest that political sentiments and social isolation are important potential mechanisms in this setting and that lack of political representation affects the mental health of individuals.

A Belowground Perspective on the Nexus between Biodiversity Change, Climate Change, and Human Well-being
Michael Koetter, et al.
Journal of Sustainable Agriculture and Environment,
Vol. 3 (2),
2024
Abstract
Soil is central to the complex interplay among biodiversity, climate, and society. This paper examines the interconnectedness of soil biodiversity, climate change, and societal impacts, emphasizing the urgent need for integrated solutions. Human-induced biodiversity loss and climate change intensify environmental degradation, threatening human well-being. Soils, rich in biodiversity and vital for ecosystem function regulation, are highly vulnerable to these pressures, affecting nutrient cycling, soil fertility, and resilience. Soil also crucially regulates climate, influencing energy, water cycles, and carbon storage. Yet, climate change poses significant challenges to soil health and carbon dynamics, amplifying global warming. Integrated approaches are essential, including sustainable land management, policy interventions, technological innovations, and societal engagement. Practices like agroforestry and organic farming improve soil health and mitigate climate impacts. Effective policies and governance are crucial for promoting sustainable practices and soil conservation. Recent technologies aid in monitoring soil biodiversity and implementing sustainable land management. Societal engagement, through education and collective action, is vital for environmental stewardship. By prioritizing interdisciplinary research and addressing key frontiers, scientists can advance understanding of the soil biodiversity–climate change–society nexus, informing strategies for environmental sustainability and social equity.

European Economic Review,
Vol. 158 (September),

Abstract
Benmir, Jaccard, and Vermandel (2023, BJV) seek to answer the following set of topical and important research questions: (i) How should monetary policy be conducted during a pandemic?, (ii) How do health considerations affect the conduct of monetary policy?, and (iii) How does the presence of contagion risk affect the main building blocks of the New Keynesian model?
