The second is the OECD’s Gini coefficient—OECD Gini—where measures before tax are used to ensure comparability with the WIOD measures. Also used is the Estimated Household Income Inequality (EHII) measure from the University of Texas Inequality Project (UTEP) - EHII Gini—which was discussed earlier (see Galbraith and Kum, 2004). Since it identifies how much more top earners are earning relative to bottom earners it is an intuitive and readily interpretable measure. The higher the ratio, the larger the inequality.
