📈In a more optimistic scenario, if all countries invested 38% of GDP in health & education, global productivity could rise to 100€/hour. Everyone gains: North America could hit 120€/hour (up from 80€), Sub-Saharan Africa 100€ (up from 9€). [9/10]

📉In a “business-as- usual” scenario where education & health spending stalls, the productivity gaps persists. By 2100, productivity would stay at ~9€/hour in Sub-Saharan Africa vs 80€ in Europe & North America. [8/10]

Since 1800, human capital spending has driven productivity. Average return on human capital > 10%/year. Returns are highest for:.· education (vs. health).· public (vs. private) spending.· poorer countries — with returns up to 20% a year.[7/10]

If we were to provide all children worldwide with the same average level of expenditure on education and health as is currently available in Europe and North America, it would cost 32% of the world’s GDP. [6/10]

🏥Public health spending per person under 65 ranges from 50€ in Sub-Saharan Africa to 3,198€ in North America (PPP € 2025) — a gap of 1 to 60. The gap widens even more with private spending (though we know that high private health costs in the US don’t necessarily lead to

Health and education have improved globally—but the spending gap between rich and poor regions is still enormous. 🎓Today, a child in Sub-Saharan Africa receives 220€ in public education spending compared to 9,025€ in North America – a gap of almost 1 to 50. [4/10]

Total public expenditure rose from 3% of global GDP in 1800 to 31% today, largely due to rising spending on health, education, and social protection. This reflects the expansion of the “global social state”, supported by states’ growing capacity to collect direct income taxes

The study draws on a new global historical database on public expenditure and revenue and their components, with a focus on education and health. This is the first database of its kind to cover all world regions over the period from 1800 to 2025. [2/10]

Children in Sub-Saharan Africa receive just 3% of the public education funding available to their peers in Europe and North America. 🧵A thread on a NEW STUDY written with @Nitin_K_Bharti, @amorygethin @mjenmana @ZhexunMO & Li Yang [1/10]. 🔗The study and a summary are available

🗓️ #GlobalJusticeProject - Key dates:. 🔸Dec 2024 – May 2026: Release of working papers & technical notes. 🔸June 4–5, 2026: Launch of the Global Justice Report at the World Inequality Conference in Paris @PSEinfo . More details about the Conference:

The #GlobalJusticeProject is a new collective research initiative developed by the World Inequality Lab @WIL_inequality, and coordinated by Lucas Chancel, Cornelia Mohren, @Rowaida_Moshrif, Moritz Odersky, @anmol_smnch and myself—along with contributions from 30+ researchers and.

What would a just distribution of socio-economic and environmental resources look like at the global level from 2025 to 2100 – both between and within countries?. How can we ensure this vision fits within planetary boundaries?. From now to June 2026, the #GlobalJusticeProject

This study is the first in a series that will form the backbone of the #GlobalJusticeProject, due to be released in June 2026. More info🔗 [8/8]

A business-as-usual scenario through 2100 is unsustainable and dangerous. But if we invest in human capital and infrastructure in the Global South, the world in 2100 could look radically different:.💶 Productivity converging to ~€100/hour worldwide.🕒Fewer working hours for all

💰Women are also paid less than men – far less than previously thought. When unpaid domestic work is factored in, the “real” gender pay gap in hourly earnings rises to 40–50%in high-income countries—double the conventional estimates of 10–20%. [6/8]

⚖️Women work longer hours than men - but much of that work is unpaid and invisible. Women provide fewer hours of economic labour than men, but significantly more hours of (unpaid) domestic labour, particularly in low- and middle-income countries. [5/8]

📈A steady rise in productivity has accompanied the long-term global reduction in working hours. At the global level, hourly productivity (net domestic product per work hour) rose from 0.7€ in 1800 to 16€ in 2025 (PPP, 2025 €). It ranges from 4€ across Subsaharan Africa to
