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.
This curve is called the "line of perfect inequality." The Gini coefficient is the ratio of the area between the line of perfect equality and the observed Lorenz curve to the area between the line of perfect equality and the line of perfect inequality. The higher the coefficient, the more unequal the distribution is.
The concept of inequality is distinct from that of poverty [5] and fairness. Income inequality metrics (or income distribution metrics) are used by social scientists to measure the distribution of income, and economic inequality among the participants in a particular economy, such as that of a specific country or of the world in general.
Inequity aversion (IA) is the preference for fairness and resistance to incidental inequalities. [1] The social sciences that study inequity aversion include sociology, economics, psychology, anthropology, and ethology. Researchers on inequity aversion aim to explain behaviors that are not purely driven by self-interests but fairness ...
Milanovic (2011) points out that overall, global inequality between countries is more important to growth of the world economy than inequality within countries. [95] While global economic growth may be a policy priority, recent evidence about regional and national inequalities cannot be dismissed when more local economic growth is a policy ...
In their work "Income Inequality and Economic Growth", they found out that the most important is the transfer channel while the least important is the human capital channel. However, the direct impact of income inequality on the rate of productivity growth accounts for more than 55 percent of its overall total effect.
One important indicator of the significance of mathematical sociology is that the general interest journals in the field, including such central journals as The American Journal of Sociology and The American Sociological Review, have published mathematical models that became influential in the field at large.
Definitions of social equity can vary, but all focus on the ideals of justice and fairness. Equity should involve the role of public administrators, who are responsible for ensuring that social services are delivered equitably. This implies taking into account historical and current inequalities among groups.
