Equal access to education is a basic human right. But in many countries gaps in education between various groups are staggering. An education Gini index - a new indicator for the distribution of human capital and welfare - facilitates comparison of education inequality across countries and over...

Equal access to education is a basic human right. But in many countries gaps in education between various groups are staggering. An education Gini index -- a new indicator for the distribution of human capital and welfare -- facilitates comparison of education inequality across countries and...

The authors use a Gini index to measure inequality in educational attainment. They present two methods (direct and indirect) for calculating an education Gini index, and generate a quinquennial data set on education Gini indexes for the over-15-population in 85 countries (1960-90). Preliminary...

We propose a non-parametric method based on a model-free formula to evaluate the tails of a risk-neutral distribution using the full cross-section of option prices at a fixed horizon. The method leads to the joint estimation of risk-neutral tail probabilities and tail expectations beyond the...

We propose a novel method to estimate risk-neutral quantiles that uses sorting to minimize an objective function given by a convex combination of call and put option prices over the range of available strike prices. We demonstrate that this new method significantly improves the accuracy of...
