In mathematics, the following inequality is known as Titu's lemma, Bergström's inequality, Engel's form or Sedrakyan's inequality, respectively, referring to the article About the applications of one useful inequality of Nairi Sedrakyan published in 1997, [1] to the book Problem-solving strategies of Arthur Engel published in 1998 and to the book Mathematical Olympiad Treasures of Titu ...
Economic inequality is an umbrella term for a) income inequality or distribution of income (how the total sum of money paid to people is distributed among them), b) wealth inequality or distribution of wealth (how the total sum of wealth owned by people is distributed among the owners), and c) consumption inequality (how the total sum of money spent by people is distributed among the spenders).
Normative interpretation of inequality through inequality indexes means that there is a relationship between an inequality index and a social-evaluation ordering defined on the incomes — incomes (nominal or real) of the members of society. Incomes are typically assigned to individuals rather than households by using an adult equivalence scale.
The Atkinson index is defined as: (, …,) = {(=) / (=) / = (,...,) = +where is individual income (i = 1, 2, ..., N) and is the mean income.. In other words, the Atkinson index is the complement to 1 of the ratio of the Hölder generalized mean of exponent 1−ε to the arithmetic mean of the incomes (where as usual the generalized mean of exponent 0 is interpreted as the geometric mean).
Jason Edward Hickel [1] (born 1982) is an anthropologist and professor at the Autonomous University of Barcelona. [2] Hickel's research and writing focuses on economic anthropology and development, and is particularly opposed to capitalism, neocolonialism, as well as economic growth as a measure of human development.
But the authors of the World Inequality Lab study reached this conclusion by tracking how much of India’s total income, as well as wealth, is held by the country’s top 1%.
Bennett's inequality, an upper bound on the probability that the sum of independent random variables deviates from its expected value by more than any specified amount Bhatia–Davis inequality , an upper bound on the variance of any bounded probability distribution
A central premise is that "social systems generate inequality, which is manifested over the life course via demographic and developmental processes." [2] Cumulative inequality and cumulative advantage/disadvantage (CAD) are two different but interrelated theories. Cumulative inequality has drawn from various theoretical traditions, including CAD.
