Economics is the social science that studies the production, distribution, and consumption of goods and services.
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 or the wealth inequality within a nation or a social group. The Gini coefficient was developed by the statistician and sociologist Corrado Gini.
Economic history is the academic learning of economies or economic events of the past. Research is conducted using a combination of historical methods, statistical methods and the application of economic theory to historical situations and institutions. The field can encompass a wide variety of topics, including equality, finance, technology, labour, and business. It emphasizes historicizing the economy itself, analyzing it as a dynamic force and attempting to provide insights into the way it is structured and conceived.
New Keynesian economics is a school of macroeconomics that strives to provide microeconomic foundations for Keynesian economics. It developed partly as a response to criticisms of Keynesian macroeconomics by adherents of new classical macroeconomics.
Thorstein Bunde Veblen was a Norwegian-American economist and sociologist who, during his lifetime, emerged as a well-known critic of capitalism.
Energy economics is a broad scientific subject area which includes topics related to supply and use of energy in societies. Considering the cost of energy services and associated value gives economic meaning to the efficiency at which energy can be produced. Energy services can be defined as functions that generate and provide energy to the “desired end services or states”. The efficiency of energy services is dependent on the engineered technology used to produce and supply energy. The goal is to minimise energy input required to produce the energy service, such as lighting (lumens), heating (temperature) and fuel. The main sectors considered in energy economics are transportation and building, although it is relevant to a broad scale of human activities, including households and businesses at a microeconomic level and resource management and environmental impacts at a macroeconomic level.
In sociology and in economics, the term conspicuous consumption describes and explains the consumer practice of buying and using goods of a higher quality, price, or in greater quantity than practical. In 1899, the sociologist Thorstein Veblen coined the term conspicuous consumption to explain the spending of money on and the acquiring of luxury commodities specifically as a public display of economic power—the income and the accumulated wealth—of the buyer. To the conspicuous consumer, the public display of discretionary income is an economic means of either attaining or of maintaining a given social status.
There are wide varieties of economic inequality, most notably income inequality measured using the distribution of income and wealth inequality measured using the distribution of wealth. Besides economic inequality between countries or states, there are important types of economic inequality between different groups of people.
A Veblen good is a type of luxury good for which the demand increases as the price increases, in apparent contradiction of the law of demand, resulting in an upward-sloping demand curve. The higher prices of Veblen goods may make them desirable as a status symbol in the practices of conspicuous consumption and conspicuous leisure. A product may be a Veblen good because it is a positional good, something few others can own.
National accounts or national account systems (NAS) are the implementation of complete and consistent accounting techniques for measuring the economic activity of a nation. These include detailed underlying measures that rely on double-entry accounting. By design, such accounting makes the totals on both sides of an account equal even though they each measure different characteristics, for example production and the income from it. As a method, the subject is termed national accounting or, more generally, social accounting. Stated otherwise, national accounts as systems may be distinguished from the economic data associated with those systems. While sharing many common principles with business accounting, national accounts are based on economic concepts. One conceptual construct for representing flows of all economic transactions that take place in an economy is a social accounting matrix with accounts in each respective row-column entry.
In economics, the Pigou effect is the stimulation of output and employment caused by increasing consumption due to a rise in real balances of wealth, particularly during deflation. The term was named after Arthur Cecil Pigou by Don Patinkin in 1948.
Juliet B. Schor is an American economist and Sociology Professor at Boston College. She has studied trends in working time, consumerism, the relationship between work and family, women's issues and economic inequality, and concerns about climate change in the environment. From 2010 to 2017, she studied the sharing economy under a large research project funded by the MacArthur Foundation. She is currently working on a project titled "The Algorithmic Workplace" with a grant from the National Science Foundation.
The permanent income hypothesis (PIH) is a model in the field of economics to explain the formation of consumption patterns. It suggests consumption patterns are formed from future expectations and consumption smoothing. The theory was developed by Milton Friedman and published in his A Theory of Consumption Function, published in 1957 and subsequently formalized by Robert Hall in a rational expectations model. Originally applied to consumption and income, the process of future expectations is thought to influence other phenomena. In its simplest form, the hypothesis states changes in permanent income, rather than changes in temporary income, are what drive changes in consumption.
Property rights are constructs in economics for determining how a resource or economic good is used and owned, which have developed over ancient and modern history, from Abrahamic law to Article 17 of the Universal Declaration of Human Rights. Resources can be owned by individuals, associations, collectives, or governments.
The Journal of Political Economy is a monthly peer-reviewed academic journal published by the University of Chicago Press. Established by James Laurence Laughlin in 1892, it covers both theoretical and empirical economics. In the past, the journal published quarterly from its introduction through 1905, ten issues per volume from 1906 through 1921, and bimonthly from 1922 through 2019. The editor-in-chief is Magne Mogstad.
The following is a list of works by the prominent American economist Milton Friedman.
The economics of religion concerns both the application of the techniques of economics to the study of religion and the relationship between economic and religious behaviours. Contemporary writers on the subject trace it back to Adam Smith (1776).
Redistribution of income and wealth is the transfer of income and wealth from some individuals to others through a social mechanism such as taxation, welfare, public services, land reform, monetary policies, confiscation, divorce or tort law. The term typically refers to redistribution on an economy-wide basis rather than between selected individuals.
Optimal capital income taxation is a subarea of optimal tax theory which studies the design of taxes on capital income such that a given economic criterion like utility is optimized.
