The University of Texas Inequality Project (UTIP)
The University of Texas Inequality Project is a small research group concerned with measuring and explaining movements of inequality in wages and earnings and patterns of industrial change around the world.We believe we can establish reasonably reliable relationships between these measures and the broader concepts of inequality. Our work has emphasized the use of Theil's T statistic to compute inequality indexes from industrial data.
