It has been used as an input for testing theories explaining the distribution of income, for example human capital theory and the theory of economic discrimination (Becker, 1993, 1971). In welfare economics , a level of feasible output possibilities is commonly distinguished from the distribution of income for those output possibilities.
Income distribution has always been a central concern of economic theory and economic policy. Classical economists such as Adam Smith, Thomas Malthus and David Ricardo were mainly concerned with factor income distribution, that is, the distribution of income between the main factors of production, land, labour and capital.
In economics, income distribution covers how a country's total GDP is distributed amongst its population. [1] 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. [2] [3]
A practical example of a Lorenz curve: the Lorenz curves of Denmark, Hungary, and Namibia. A Lorenz curve always starts at (0,0) and ends at (1,1). The Lorenz curve is not defined if the mean of the probability distribution is zero or infinite. The Lorenz curve for a probability distribution is a continuous function. However, Lorenz curves ...
In economics, the absolute income hypothesis concerns how a consumer divides their disposable income between consumption and saving. [1] It is part of the theory of consumption proposed by economist John Maynard Keynes. The hypothesis was subject to further research in the 1960s and 70s, most notably by American economist James Tobin (1918 ...
The initial distribution of income determines whether an economy converges to a low-education, low-income steady-state equilibrium, or high-income, high education steady-state equilibrium. In particular, the model predicts that inequality have an adverse effect on human capital formation and economic growth in all but the very poor economies.
Optimal tax theory or the theory of optimal taxation is the study of designing and implementing a tax that maximises a social welfare function subject to economic constraints. [1] The social welfare function used is typically a function of individuals' utilities , most commonly some form of utilitarian function, so the tax system is chosen to ...
Until A Theory of Consumption Function, the Keynesian absolute income hypothesis and interpretation of the consumption function were the most advanced and sophisticated. [2] [3] In its post-war synthesis, the Keynesian perspective was responsible for pioneering many innovations in recession management, economic history, and macroeconomics.
