Happiness inequality and income inequality: theories, measurements and trends

Abstract

Happiness is self-reported by individuals and people report different levels of happiness. Some people report high levels while others report low levels of happiness. The magnitude of the difference between the reported levels of happiness reflects happiness inequality. Individuals and countries have access to income, but income is not shared equally between countries and individuals. Individuals or countries may have a greater portion of income compared to other individuals or countries, such disparity in income earnings is known as income inequality.
