3 basic economic questions
1. What to produce?
2. How to produce it?
3. For whom to produce?
Private sector
The economic activity of private individuals or firms.
Private sector's main aim
The private sector's main aim is to earn profit for its owners.
Public sector
The economic activity directly involving the government, such as the provision of state education and healthcare services.

Needs

Wants
Goods and services that are not necessary for survival but are demanded by economic agents to fulfil their desires.
Economic goods
Goods which are limited in supply.
Free goods
Goods which are unlimited in supply, such as air and seawater. Hence there is no opportunity cost in terms of their output and consumption.
Economics
The study of how resources are allocated to satisfy the unlimited needs and wants of individuals, governments and firms in an economy.
The basic economic problem
It is concerned with how to best allocate scarce resources in order to satisfy people's unlimited needs and wants.
The four factors of production
1. Land
2. Labour
3. Capital
4. Enterprise
Land and its reward
The natural resources required in the production process. The reward for land is rent.
Labour and its reward
The human resources required in the production process. The reward for labour are wages and salaries.
Capital and its reward
The manufactured resources required in the production process. The reward for capital is interest.
Enterprise and its reward
The skills a business person requires to combine and manage the other three factors of production successfully. The reward for enterprise is profit.
Geographical mobility
The extent to which labour is willing and able to move to different locations for employment purposes.
Occupational mobility
The extent to which labour is able to move between jobs.
Opportunity cost
The cost of the next best opportunity forgone when making a decision.
The production possibility curve (PPC)
It represents the maximum combination of goods and services which can be produced in an economy.
What does an inwards shift on a PPC represent?
It represents a decrease in the productive capacity of the economy
Microeconomics
The study of particular markets and sections of the economy rather than the economy as a whole.
Macroeconomics

Non price factors affecting supply

Market system
The method of allocating scarce resources through the market forces of demand and supply.
Market equilibrium
When the demand of a product matches the supply, so there is no excess demand (shortage) or excess supply (surplus).
Market disequilibrium
When the price for a product is too high (resulting a surplus) or too low (resulting a shortage).
Price mechanism
The system of relying on the market forces of demand and supply to allocate resources.
Demand
The willingness and ability of consumers to pay at a given price for a good or service.
Law of demand
The inverse relationship between the price of a good or service and the quantity demanded.
Supply
The willingness and ability of suppliers to provide goods and services at given price levels.
Law of supply
The positive relationship between price and quantity supplied of a product.
Sales revenue
The sum of money received from the sale of a good or service. Formula:
Price x Quantity demanded
Profit
The amount of money a business receives in excess of its expenses.Formula:
Total Revenue - Total Costs
Market economy
This economic system relies on the market forces of demand and supply to allocate resources efficiently with minimal government intervention.
Planned economy
This economic system relies on the government allocating resources.
Mixed economy
This economic system is a combination of the planned and market economy system, with some resources being owned and controlled by private individuals and firms and some resources being owned and controlled by the government.
Advantages of the market economy system
1. Efficiency - competition
2. Freedom of choice3. Incentives - profit motives
Disadvantages of the market economy system
1. Income and wealth inequalities2. Environmental issues3. Social hardship4. Wasteful competition
Economic system
The way an economy is organized in terms of how it best allocates scarce resources.
Market failure
When the market forces of demand and supply are unsuccessful in allocating resources efficiently and cause external costs or external benefits.
Private costs

External costs
The negative side-effects of production or consumption incurred by third parties for which no compensation is paid.
Social costs
The true costs of consumption or production to society as a whole.
Private benefits

External benefits
The positive side-effects of production and consumption experienced by third parties for which no money is paid by the beneficiary.
Social benefits
The true benefits of consumption or production.
Public goods
Goods and services that are non-excludable and non-rivalrous. These are a cause of market failure as there is a lack of profit motive to produce them.
Merit goods
Goods and services which when consumed create positive spillover effects in an economy.
Demerit goods
Goods and services which when consumed cause negative spillover effects in an economy.
Maximum price
This occurs when the government sets the price under the market equilibrium to encourage consumption.
Minimum price
This occurs when the government sets the price above the market equilibrium in order to encourage output of a good or service.
Privatisation
The transfer of ownership of assets from the public sector to the private sector.
Nationalisation
The purchase of private sector assets by the government.
Money
Any commodity that can be used as a medium of exchange and is widely accepted for the purchase of goods and services.

2. Unit of account
3. Store of value
4. Standard of deferred payment
Characteristics of money

2. Divisibility
3. Portability

7. Uniformity
Bartering
The act of swapping items in exchange for other items.
Problems with bartering
