We analyze the reallocations of educational expenditures required to equalize opportunities, according to the theory of Roemer (1998). Using the NLSYM data set, we find that implementing an equal-opportunity policy across men of different races, by using educational finance as the instrument, and ensuring that no race received less than the average observed nationally, would require spending ni...

The first application of Szemerédi’s powerful regularity method was the following celebrated Ramsey-Turán result proved by Szemerédi in 1972: any K4-free graph on n vertices with independence number o(n) has at most ( 18 +o(1))n 2 edges. Four years later, Bollobás and Erdős gave a surprising geometric construction, utilizing the isoperimetric inequality for the high dimensional sphere, of a K4-...

Lorenz curve and Gini index are the famous tools of income inequality. When one wants to study income inequality of a class of individuals, Partial Lorenz Curve is introduced and the corresponding measure of inequality called Partial Gini Index is defined. Partial Gini Index (PGI) is derived on Partial Lorenz Curve (PLC). Partial orderings are defined for comparison of partial Lorenz curves. Fo...

In the literature of poverty, it is well known that every poverty index should be sensitive to the incidence of poverty, the intensity of poverty and to the inequality among the poo individuals. However, the inequality among the poor could be measured analyzing either the income of the poor distribution, or the gap of the poor distribution. Depending on the side we focus on, contradictory resul...
