Amartya Sen, Premio Nobel de Econom a en 1998, public esta obra por primera vez en 1973. Serie de reflexiones ayudan no s lo a medir, sino a explicar la desigualdad. Con su trabajo ha demostrado que las hambrunas no son producto del fracaso o consecuencia de la sequ a, sino del hecho primordial de que los sectores m s pobres del mundo no tienen el derecho individual de que se les proporcione alimentos.

But the main reason for the confusion is a simple mistake: An entropy measure like Theil's index is not an entropy, it is a redundancy. A redundancy is actual entropy of a system deducted from the possible maximum entropy of that system. Therefore, redundancy yields a high value for inequal distribution, whereas entropy is high for even distribution.
Calling Theil's measure an "entropy" even confused Amartya Sen. From Amartya Sen's "On Economic Inequality" I learned a lot about inequality measures. But entropy seems not do go down too well with him (1973) and his co-author James E. Foster (1997). When describing the "interesting" "Theil entropy" (chapter 2.11), Sen sees a contradiction between entropy being a measure of "disorder" in thermodynamics and entropy being a measure for "equality". If you assume that equality is "order" and thus a antonym for "disorder", then you may believe - Sen even calls it a "fact" - that the Theil coefficient is computed from an "arbitrary formula". However, there is no contradiction: As you know by now, the Theil index is a redundancy, not an entropy. That is the answer to Sen's objection.
Sen and Foster had another complaint. They didn't think, that Theil's index really yields to "intuition". It may help to remember, that the Theil index (I prefer to call it Theil redundancy) is 0% for a 50%:50% distribution (equality) and close to 100% for an equivalent to the (in)famous 80%:20% distribution. And how much does the Gini index yield to intuition? ( )
