Important Definitions in Economics

  • Per capita income (PCI) / Average income: The average income earned per person in a given area (city, region, country, etc.) in a specified year. It is calculated by dividing the area’s total income by its total population.
  • Literacy rate: The number of persons who is 7 or above and has the ability to read, write and understand in any language. It is calculated by dividing ‘number of literate persons aged 7 or above’ to the total ‘population aged 7 or above’ and multiplying by 100.
  • Bank Rate / Discount Rate: The rate of interest which a central bank charges on its loans and advances to a commercial bank.
  • Prime Lending Rate / Prime Rate: The interest rate charged by banks to their largest, most secure, and most creditworthy customers on short-term loans.
  • Neo-Malthusian Theory: Malthusian theory is based on the idea that population growth will outstrip the ability to feed people. Malthus called for abstinence from sex was necessary to stop population growth.
  • General Equilibrium Theory (Walras): Explains the behavior of supply, demand, and prices in a whole economy with several or many interacting markets, by seeking to prove that the interaction of demand and supply will result in an overall general equilibrium.
  • Gresham’s law: A monetary principle stating that “bad money drives out good”. For example, if there are two forms of commodity money in circulation, which are accepted by law as having similar face value, the more valuable commodity will gradually disappear from circulation.

Types of Unemployment

  1. Disguised Unemployment: A kind of unemployment where some people seem to be employed but are actually not. This type usually exists where part of the labor force is either left without work or is working in a redundant manner where worker productivity is essentially zero.
  2. Frictional Unemployment: The unemployment which exists in any economy due to people being in the process of moving from one job to another.
  3. Seasonal Unemployment: Type of employment when people are unemployed at particular times of the year when demand for labour is lower than usual.
  4. Cyclical Unemployment: A factor of overall unemployment that relates to the regular ups and downs, or cyclical trends in growth and production, that occur within the business cycle.
  5. Structural unemployment: A form of unemployment caused by a mismatch between the skills that workers in the economy can offer and the skills demanded of workers by employers.
  6. Voluntary unemployment: The situation when the worker deliberately chooses not to work because of a low wage scale or not able to find out the suitable employment for him.
  7. Casual unemployment: The unemployment when the worker is employed on a day-to-day basis for a contractual job and have to leave it once the contract terminates.
  8. Technological unemployment: The loss of jobs caused by technological change. Such change typically includes the introduction of labour-saving machines or automation.

Economic System Based on Inter-Relation (Open, Closed)

1. Open Economy

An economy in which there are economic activities between the domestic community and outside.

2. Closed Economy

A self-sufficient economy, which means no imports come into the country and no exports leave the country.

Economic System Based on Production (Capitalism, Socialism, Mixed economy)

An economy is an area of the production, distribution, or trade, and consumption of goods and services by different agents.

1. Capitalist Economy (Free-Market Economy)

A country’s trade and industry are controlled by private owners for profit, rather than by the state.

  • Works on Laissez-faire (free from government intervention) economic system.
  • Properties: Private Property, Price Mechanism, Freedom of Enterprise, Sovereignty of that consumer, Profit Motive, No Government Interference
  • Capitalist Countries: UK, UAE, Australia

2. Socialist Economy

Socialism is an economic system where everyone in society equally owns the factors of production.

  • Creator: Carl Marx
  • The four factors of production are labor, entrepreneurship, capital goods, and natural resources.
  • Socialist Countries: People’s Republic of China

3. Mixed Economy

A mixed economy is a system that combines the characteristics of market, command and traditional economies.

  • Creator: John Maynard Keynes, author of The General Theory of Employment, Interest and Money

  • It was the longest, deepest, and most widespread depression of the 20th century.
  • Most of the counties adopted the mixed economy after this.

Types of Goods in Economics

  1. Normal Goods – Any good for which demand increases when income increases, i.e. with a positive income elasticity of demand.
  2. Luxury good / Upmarket good – A good for which demand increases more than proportionally as income rises, and is a contrast to a “necessity good”, where demand increases proportionally less than income. Luxury goods is often used synonymously with superior goods and Veblen goods.
  3. Inferior good – A good whose demand decreases when consumer income rises unlike normal goods, for which the opposite is observed.
  4. Complementary Goods – A complementary good is a good whose use is related to the use of an associated or paired good. Two goods (A and B) are complementary if using more of good A requires the use of more of good B. For example, the demand for one good (printers) generates demand for the other (ink cartridges).
  5. Substitute goods – At least two products that could be used for the same purpose by the same consumers. If the price of one of the products rises or falls, then demand for the substitute goods or substitute good (if there is just one other) is likely to increase or decline.
  6. Giffen good – A good that is in greater demand as its price increases. For example, if the price of an essential food staple, such as rice, rises it may mean that consumers have less money to buy more expensive foods, so they will actually be forced to buy more rice.
  7. Veblen / Snob good – A Veblen good is a good for which demand increases as the price increases, because of its exclusive nature and appeal as a status symbol.
  8. Public goods – An item whose consumption is not decided by the individual consumer but by the society as a whole, and which is financed by taxation.
  9. Merit goods – Those goods and services that the government feels that people will under-consume, and which ought to be subsidised or provided free at the point of use so that consumption does not depend primarily on the ability to pay for the good or service.
  10. Demerit goods – A demerit good is “a good or service whose consumption is considered unhealthy, degrading, or otherwise socially undesirable due to the perceived negative effects on the consumers themselves”.
  11. Private goods – A private good is “an item that yields positive benefits to people” that is excludable, i.e. its owners can exercise private property rights, preventing those who have not paid for it from using the good or consuming its benefits; and rivalrous, i.e. consumption by one necessarily prevents that of another.
  12. Free goods – A resource, such as sunlight or air, which is so abundant that its availability is not a constraint on economic activity.
  13. Consumption / Consumer / Final goods – Any commodity that is produced or consumed by the consumer to satisfy current wants or needs. Consumer goods are ultimately consumed, rather than used in the production of another good.
  14. Capital goods – Goods that are used in producing other goods, rather than being bought by consumers.
  15. Intermediate goods / Producer goods / Semi-finished products – Goods which are under process goods, such as partly finished goods, used as inputs in the production of other goods including final goods.
  16. Investment goods – The goods that enable production, and are the main input into new installed capital. e.g. machine,factory,equipment etc.

Types of Market Structures

1. Monopolistic Competition

Monopolistic competition is a type of imperfect competition such that many producers sell products that are differentiated from one another and hence are not perfect substitutes.

2. Perfect Competition

3. Monopoly

A market structure characterized by a single seller/firm, selling a unique product in the market.

Bilateral monopoly: A market structure consisting of both a monopoly (a single seller) and a monopsony (a single buyer).

  2. Perfectly Inelastic Demand – A demand where a consumer will buy a good or service regardless of the increase or decrease of price.
  3. Relatively Elastic Demand – A demand where relatively small changes in price cause relatively large changes in quantity.
  4. Relatively Inelastic Demand – A demand where where quantity demanded doesn’t change much with respect to change in price of the good.
  5. Unitary Elastic Demand – The demand for a good is unitary elastic if a change in the price of that good causes an equal change in quantity demanded.

Deficit and Surplus: A deficit occurs when the government spends more than it taxes; and a surplus occurs when a government taxes more than it spends.
