EARN MONEY

INCOME

Rrefers 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.

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)

Meaning in economics and use in economic theory

In economics, factor income is the flow (that is, measured per unit of time) of revenue accruing to a person or nation from labor services and from ownership of land and capital.
In consumer theory 'income' is another name for the "budget constraint," an amount Y to be spent on different goods x and y in quantities x and y at prices Px and Py. The basic equation for this is

Y = Px • x + Py • y.

This equation implies two things. First buying one more unit of good x implies buying Px/Py less units of good y. So, Px/Py 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 Y, 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 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

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 injusticeNational income, measured by statistics such as the Net National Income (NNI), measures the total income of individuals, corporations, and government in the economy.

MONEY

Money is anything that is generally accepted as payment for goods and services and repayment of debts.The main uses of money are as a medium of exchange, a unit of account, and a store of value. Some authors explicitly require money to be a standard of deferred payment.The term "price system" is sometimes used to refer to methods using commodity valuation or money accounting systems.
The word "money" is believed to originate from a temple of Hera, located on Capitoline one of Rome's seven hills. In the ancient world Hera was often associated with money. The temple of Juno Moneta at Rome was the place where the mint of Ancient Rome was located.The name "Juno" may derive from the Etruscan goddess Uni (which means "the one", "unique", "unit", "union", "united") and "Moneta" either from the Latin word "monere" (remind, warn, or instruct) or the Greek word "moneres" (alone, unique).

Economic characteristics
Money is generally considered to have the following characteristics, which are summed up in a rhyme found in older economics textbooks: "Money is a matter of functions four, a medium, a measure, a standard, a store." That is, money functions as a medium of exchange, a unit of account, a standard of deferred payment, and a store of value.There have been many historical arguments regarding the combination of money's functions, some arguing that they need more separation and that a single unit is insufficient to deal with them all. One of these arguments is that the role of money as a medium of exchange is in conflict with its role as a store of value: its role as a store of value requires holding it without spending, whereas its role as a medium of exchange requires it to circulate. Others argue that storing of value is just deferral of the exchange, but does not diminish the fact that money is a medium of exchange that can be transported both across space and time.'Financial capital' is a more general and inclusive term for all liquid instruments, whether or not they are a uniformly recognized tender.

Main article: Medium of exchange
Money is used as an intermediary for trade, in order to avoid the inefficiencies of a barter system, which are sometimes referred to as the 'double coincidence of wants problem'. Such usage is termed a medium of exchange.

Main article: Unit of account
A unit of account is a standard numerical unit of measurement of the market value of goods, services, and other transactions. Also known as a "measure" or "standard" of relative worth and deferred payment, a unit of account is a necessary prerequisite for the formulation of commercial agreements that involve debt.
Divisible into small units without destroying its value; precious metals can be coined from bars, or melted down into bars again.
Fungible: that is, one unit or piece must be perceived as equivalent to any other, which is why diamonds, works of art or real estate are not suitable as money.
A specific weight, or measure, or size to be verifiably countable. For instance, coins are often made with ridges around the edges, so that any removal of material from the coin (lowering its commodity value) will be easy to detect.

Main article: Store of value
To act as a store of value, a commodity, a form of money, or financial capital must be able to be reliably saved, stored, and retrieved — and be predictably useful when it is so retrieved. Fiat currency like paper or electronic currency no longer backed by gold in most countries is not considered by some economists to be a store of value.
