Calling #Theil's #inequality measure an "#entropy" irritated #AmartyaSen. From Amartya Sen's "#OnEconomicInequality" (#OEI) I learned a lot about #InequalityMeasures. But entropy seems not do go down too well with him (1973) and his co-author #JamesEricFoster (1997): When describing the "interesting" "#TheilEntropy" (chapter 2.11), Sen sees a contradiction between entropy being a measure of "#disorder" in #thermodynamics and entropy being a measure for "#equality".
@woo -- #Entropy: I try to avoid to use the terms "#order" and "#disorder".
#SocialSciences: The the measures developped by #AnthonyBarnesAtkinson, #SergeChristopheKolm and #HenriTheil are based on the #ShannonEntropy.
#Thermodynamics: I recommend "Entropy-Demystified, the Second Law of Thermodynamics Reduced to Plain Common Sense" (World Scientific, Singapore, 2007) by #AriehBenNaim (http://www.ariehbennaim.com). The important chapters 1 and 8 are available on-line: http://www.ariehbennaim.com/demo-images/B7-Ch1-8-Pref-.pdf.
