The James M. and Cathleen D. Stone Center on Socio-Economic Inequality—known as the Stone Center—was launched on September 1, 2016. It renames and expands the Graduate Center’s Luxembourg Income Study (LIS) Center, which opened its doors at the Graduate Center in 2009. The mission of the Stone Center is to build and disseminate knowledge related to the causes, nature, and consequences of multiple forms of socio-economic inequality. Although the Stone Center’s associated faculty and students have diverse interests and utilize a range of methods, they share a commitment to scholarship that is quantitative, data-driven, interdisciplinary, and policy-oriented, and that addresses questions that are cross-nationally comparative and/or global in scope.
