World Inequality Report 2026 coordinated by Lucas Chancel, Ricardo Gómez-Carrera, Rowaida Moshrif, Thomas Piketty et al. published by World Inequality Lab, 2025.
The World Inequality Report 2026 (WIR 2026) marks the third edition in this flagship series, following the 2018 and 2022 editions. These reports draw from the work of over 200 scholars from all over the world, affiliated with the World Inequality Lab and contributing to the largest database on the historical evolution of global inequality. This collective endeavor represents a significant contribution to global discussions on inequality. The team has helped reshape how policymakers, scholars, and citizens understand the scale and causes of inequality, foregrounding the separatism of the global rich and the urgent need for top-end tax justice. Their findings have informed national and international debates on fiscal reform, wealth taxation, and redistribution in forums from national parliaments to the G20.
