Attention inequality is the inequality of distribution of attention across users on social networks, [1] people in general, [2] and for scientific papers. [3] [4] Yun Family Foundation introduced "Attention Inequality Coefficient" as a measure of inequality in attention and arguments it by the close interconnection with wealth inequality. [5]
Attention inequality is related to economic inequality since attention is an economically scarce good. [2] [6] Same measures and concepts as in classical economy can be applied for attention economy. The relationship develops also beyond the conceptual level—considering the AIDA process, attention is the prerequisite for real monetary income on the Internet. [7] On data of 2018, [8] a significant relationship between likes and comments on Facebook to donations is proven for non-profit organizations.
As data of 2008 shows, 50% of the attention is concentrated on approximately 0.2% of all hostnames, and 80% on 5% of hostnames. [6] The Gini coefficient of attention distribution lay in 2008 at over 0.921 for such commercial domains names as ac.jp and at 0.985 for .org-domains.
The Gini coefficient was measured on Twitter in 2016 for the number of followers as 0.9412, for the number of mentions as 0.9133, and for the number of retweets as 0.9034. For comparison, the world's income Gini coefficient was 0.68 in 2005 and 0.904 in 2018. More than 96% of all followers, 93% of the retweets, and 93% of all mentions are owned by 20% of Twitter. [1]
At least for scientific papers, today's consensus states that inequality is unexplainable by variations of quality and individual talent. [9] [10] [11] The Matthew effect plays a significant role in the emergence of attention inequality—those who already enjoy a lot of attention get even more attention and those who do not lose even more. [12] [13] Ranking algorithms based on relevance to the user have been found to alleviate the inequality of the number of posts across topics. [7]
In economics, the Gini coefficient, also known as the Gini index or Gini ratio, is a measure of statistical dispersion intended to represent the income inequality, the wealth inequality, or the consumption inequality within a nation or a social group. It was developed by Italian statistician and sociologist Corrado Gini.
In economics, the Lorenz curve is a graphical representation of the distribution of income or of wealth. It was developed by Max O. Lorenz in 1905 for representing inequality of the wealth distribution.
Economic inequality is an umbrella term for a) income inequality or distribution of income, b) wealth inequality or distribution of wealth, and c) consumption inequality. Each of these can be measured between two or more nations, within a single nation, or between and within sub-populations.
In economics, income distribution covers how a country's total GDP is distributed amongst its population. Economic theory and economic policy have long seen income and its distribution as a central concern. Unequal distribution of income causes economic inequality which is a concern in almost all countries around the world.
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. While different theories may try to explain how income inequality comes about, income inequality metrics simply provide a system of measurement used to determine the dispersion of incomes. The concept of inequality is distinct from poverty and fairness.
The distribution of wealth is a comparison of the wealth of various members or groups in a society. It shows one aspect of economic inequality or economic heterogeneity.
In economics, personal income refers to the total earnings of an individual from various sources such as wages, investment ventures, and other sources of income. It encompasses all the products and money received by an individual.
Income inequality has fluctuated considerably in the United States since measurements began around 1915, moving in an arc between peaks in the 1920s and 2000s, with a 30-year period of relatively lower inequality between 1950 and 1980.
Income segregation is the separation of various classes of people based on their income. For example, certain people cannot get into country clubs because of insufficient funds. Another example of income segregation in a neighborhood would be the schools, facilities and the characteristics of a population. Income segregation can be illustrated in countries such as the United States, where racial segregation is a major cause of income inequality.
Social inequality occurs when resources within a society are distributed unevenly, often as a result of inequitable allocation practices that create distinct unequal patterns based on socially defined categories of people. Differences in accessing social goods within society are influenced by factors like power, religion, kinship, prestige, race, ethnicity, gender, age, sexual orientation, and class. Social inequality usually implies the lack of equality of outcome, but may alternatively be conceptualized as a lack of equality in access to opportunity.
The friendship paradox is the phenomenon first observed by the sociologist Scott L. Feld in 1991 that on average, an individual's friends have more friends than that individual. It can be explained as a form of sampling bias in which people with more friends are more likely to be in one's own friend group. In other words, one is less likely to be friends with someone who has very few friends. In contradiction to this, most people believe that they have more friends than their friends have.
Kinetic exchange models are multi-agent dynamic models inspired by the statistical physics of energy distribution, which try to explain the robust and universal features of income/wealth distributions.
The Matthew effect of accumulated advantage, sometimes called the Matthew principle, is the tendency of individuals to accrue social or economic success in proportion to their initial level of popularity, friends, and wealth. It is sometimes summarized by the adage or platitude "the rich get richer and the poor get poorer". The term was coined by sociologists Robert K. Merton and Harriet Zuckerman in 1968 and takes its name from a loose interpretation of the Parable of the Talents in the biblical Gospel of Matthew.
China's current mainly market economy features a high degree of income inequality. According to the Asian Development Bank Institute, “before China implemented reform and opening-up policies in 1978, its income distribution pattern was characterized as egalitarian in all aspects.”
Brazil has been tackling problems of income inequality despite high rates of growth. Its GDP growth in 2010 was 7.5%. In recent decades, there has been a decline in inequality for the country as a whole. Brazil's GINI coefficient, a measure of income inequality, has slowly decreased from 0.596 in 2001 to 0.543 in 2009. However, the numbers still point to a rather significant problem of income disparity.
Income inequality in India refers to the unequal distribution of wealth and income among its citizens. According to the CIA World Factbook, the Gini coefficient of India, which is a measure of income distribution inequality, was 35.2 in 2011, ranking 95th out of 157. Wealth distribution is also uneven, with one report estimating that 54% of the country's wealth is controlled by millionaires, the second highest after Russia, as of November 2016. The richest 1% of Indians own 58% of wealth, while the richest 10% of Indians own 80% of the wealth. This trend has consistently increased, meaning the rich are getting richer much faster than the poor, widening the income gap. Inequality worsened since the establishment of income tax in 1922, overtaking the British Raj's record of the share of the top 1% in national income, which was 20.7% in 1939–40. According to Oxfam India's report of 2023, "Survival of the Richest: India Story," just 5 per cent of Indians own more than 60 per cent of the country's wealth, while the bottom 50 per cent of the population possess only 3 per cent of the wealth. It also says that between 2012 and 2021, 40% of wealth generated in India has gone to just 1% of the total population and 3% of the wealth has gone to bottom 50%. The number of hungry Indians increased to 350 million in 2022 from 190 million in 2018, while the number of billionaires has increased from 102 in 2020 to 166 in 2022. The covid pandemic reduced the income of the poor, but the wealthy did well. The combined wealth of India's 100 richest is now above $600 billion, which is equivalent to India's Union Budget for 18 months. According to Union Government 's own submission to Supreme Court of India, widespread hunger has caused 65% of deaths of children under the age of 5 in 2022. Saurabh Mukherjee, the founder and CIO of Marcellus Investment Managers, along with his colleague Nandita Rajhansa, has coined the term "Octopus Class" to depict 2 lakh families or around 1 million people in India who control 80% of India's wealth. This class has consolidated financial, social and political power and has continuously pushed its 'tentacles' in every profitable activity they are interested in, aided by liberalisation and consequent growth of globalised economy since 1991.
China has been one of the fastest growing economies in the world since the implementation of its reform policies in the late 1970s. This economic growth has been accompanied by a rapid increase in income inequality that China's Gini coefficient increased from 0.310 in 1981 to 0.468 in 2018. Several policies have been introduced with the aim to alleviate the income inequality in China.
The Kaniadakis Weibull distribution is a probability distribution arising as a generalization of the Weibull distribution. It is one example of a Kaniadakis κ-distribution. The κ-Weibull distribution has been adopted successfully for describing a wide variety of complex systems in seismology, economy, epidemiology, among many others.
