Income, refers to consumption opportunity gained by an entity within a specified time frame, which is generally expressed in monetary terms.^[1] However, for households and individuals, "income is the sum of all the wages, salaries, profits, interests payments, rents and other forms of earnings received... in a given period of time."^[2] For firms, income generally refers to net-profit: what remains of revenue after expenses have been subtracted.^[3] In the field of public economics, it may refer to the accumulation of both monetary and non-monetary consumption ability, the former being used as a proxy for total income.^[1]

Remuneration may be by salary or wages plus employee benefits.

Income inequality

Income inequality refers to the extent to which income is distributed in an uneven manner. Within a society can be measured by various methods, including the Lorenz curve and the Gini coefficient. Economists generally agree that certain amounts of inequality are necessary and desirable but that excessive inequality leads to efficiency problems and social injustice.^[1]

National income, measured by statistics such as the Net National Income (NNI), measures the total income of individuals, corporations, and government in the economy. For more information see measures of national income and output.

Full and Haig-Simons income

Main article: Haig-Simons income

Full income refers to the accumulation of both, monetary and non-monetary consumption ability of any given entity, such a person or household. According to the what economist Nicholas Barr describes as the "classical definition of income:" the 1938 Haig-Simons definition, "income may be defined as the... sum of (1) the market value of rights exercised in consumption and (2) the change in the value of the store of property rights..." Since the consumption potential of non-monetary goods, such as leisure, cannot be measured, monetary income may be thought of as a proxy for full income.^[1] As such, however, it is criticized for being unreliable, i.e. failing to accurately reflect affluence and that is consumption opportunities of any given agent. It omits the utility a person may derive from non-monetary income and, on a macroeconomic level, fails to accurately chart social welfare. According to Barr, "in practice money income as a proportion of total income varies widely and unsystematically. Non-observability of full-income prevent a complete characterization of the individual opportunity set, forcing us to use the unreliable yardstick of money income." On the macro-economic level, national per-capita income, increases with the consumption of activities that produce harm and omits many variables of societal health.^[1]

+[[Remuneration]] may be by [[salary]] or [[wages]] plus [[employee benefits]].
-The International Accounting Standards Board uses this definition:
-:"Income is increases in economic benefits during the accounting period in the form of inflows or enhancements of assets or decreases of liabilities that result in increases in equity, other than those relating to contributions from equity participants." [F.70] (IFRS Framework)
-[[Remuneration]] may be by [[salary]] or [[wages]]]].
-==Meaning in economics and use in economic theory==
-In [[economics]], [http://bea.gov/bea/glossary/glossary.cfm?key_word=Factor_Income&letter=F#Factor_Income factor income] is the [[Stock and flow|flow]] (that is, measured per unit of time) of revenue accruing to a person or nation from labor services and from ownership of [[Land (economics)|land]] and [[Capital (economics)|capital]].
-In [[consumer theory]] 'income'  is another name for the "budget constraint," an amount <tt>Y</tt> to be spent on different goods x and y in quantities <tt>x</tt> and <tt>y</tt> at prices <tt>Px</tt> and <tt>Py</tt>.  The basic equation for this is
-: <tt>Y = Px • x + Py • y</tt>.
-This equation implies two things. First  buying one more unit of good x implies buying <tt>Px/Py</tt> less units of good y.  So, <tt>Px/Py</tt> is the ''relative'' price of a unit of x as to the number of units given up in y.  Second, if the price of x falls for a fixed <tt>Y</tt>, then its relative price falls.  The usual hypothesis is that the quantity demanded of x would increase at the lower price, the [[law of demand]].  The generalization to more than two goods consists of modelling y as a [[composite good]].
-The theoretical generalization to more than one period is a multi-period [[wealth (economics)|wealth]] and income constraint. For example the same person can gain more productive skills or acquire more productive income-earning assets to earn a higher income. In the multi-period case, something might also happen to the economy beyond the control of the individual to reduce (or increase) the flow of income. Changing measured income and its relation to consumption over time might  be modeled accordingly, such as in the [[permanent income hypothesis]].
 == Income inequality ==
 [[Income inequality]] refers to the extent to which income is distributed in an uneven manner. Within a society can be measured by various methods, including the [[Lorenz curve]] and the [[Gini coefficient]]. Economists generally agree that certain amounts of inequality are necessary and desirable but that excessive inequality leads to efficiency problems and social injustice.<ref name="Barr"/>
 National income, measured by statistics such as the [[Net National Income]] (NNI), measures the total income of individuals, corporations, and government in the economy.  For more information see [[measures of national income and output]].
-== Income in Philosophy and Ethics ==
-Throughout history, many have written about the impact of income growth on [[morality]] and [[society]]. [[Saint Paul]] wrote 'The love of money causes all kinds of trouble' ([[1 Timothy]] 6:10 ([[Contemporary English Version|CEV]]).
-Some scholars have come to the conclusion that material progress and prosperity, as manifested in continuous income growth at both individual and national level, provide the indispensable foundation for sustaining any kind of morality. This argument was explicitly given by [[Adam Smith]] in his ''Theory of Moral Sentiments''{{Fact|date=April 2009}}, and has more recently been developed in depth by Harvard economist [[Benjamin M. Friedman|Benjamin Friedman]] in his well-acclaimed recent book ''The Moral Consequences of Economic Growth''{{Fact|date=April 2009}}.
