Chapter 1: Macroeconomics Flashcards
What is Economics?
Economics is the study of how individuals, businesses governments and other organisations choose to use scarce resources to satisfy their numerous needs and wants in a manner that is efficient and equitable.
What are the four ELEMENTS of Economics?
- SCARCITY OF RESOURCES
- MAKING CHOICES
- EFFICIENCY
- EQUITABLY
What does the element of scarcity of resources imply?
- Resources are finite/limited
- All resources have more than one use
- Every time we use a resource for one purpose we cannot use it for another purpose
- We need to make a choice
What does the element of making choices imply?
- People have to make a choice because their wants outweigh resources available
- Wants are unlimited/Infinite
- It is HUMAN NATURE to always want more, better, newer and nicer things
- Subsistence economies were based on what nature can provide
- Modern Economies are based on the availability of money one has (INCOME)
What does the element of efficiency imply?
- It is concerned with how well resources are used to produce an end result (OUTPUT)
- One person’s satisfaction can only be increased if some one else’s satisfaction is lowered
- There must not be a better way of using the available resources that will increase satisfaction
- Given output must have been produced with the minimum number of inputs
- Either substituting one input for another or reorganizing the scale of production must achieve no increase in output
What does the principle of Equitability imply?
- Fairness and justness
- Having concern for others
- Businesses should not exploit clients or workers for the sake of ever increasing profits
- Natural resources must not be used up to the extent of nothing being left for future generations
- Government ensures benefit of society’s resources are distributed fairly among society members, this is done through taxation etc.

- INDIVIDUAL DECISION MAKING UNITS
- THE METHOD OF MICROECONOMICS
- PRESENTATION
Why is microeconomics useful?
It helps us to zoom in on a component and analyse relationships involved, reasons why it exists and ways to strengthen and weaken the relationship
What does macroeconomics focus on?
focuses on entire economy
E.g inflation, unemployment, government expenditure and production.
What is the difference between microeconomics and macroeconomics?
MICROECONOMICS: -Small element -Capitalism -Individual performance MACROECONOMICS: -Aggregate -Socialism -Overall performance

- over simplified for understanding relationship between variables
How are models presented?
in quantitative expressions, illustrations, diagrams and statements in writing
What are the FOUR scarce factors of production?
Human Resources
Natural resources
Human-made resources
Entrepreneurial talents
Why is there absolute scarcity?
resources are finite, factors of production are scarce, therefore only a limited amount of goods & services and be produced
What is relative scarcity?
the human nature of people makes them want more, better, newer and nicer things, wants are infinite
as countries increase production capacity, the appetite of the consumers also increase
What is the difference between scarcity and poverty?
Scarcity: -Basic needs satisfied -Affects everyone -Unsatisfied wants will always exist Poverty: -No satisfaction of basic needs -Affects only poor -Earn less than minimum income
What are economic goods?
- they are scarce
- they have utility and value
- people economise
What are free goods?
- plentiful
- have utility but no commercial value
- do not belong to anybody
What are alternatives?
the choices we make for using a particular resource, the purpose is meant to satisfy
What are choices?
Decisions we make to achieve largest possible satisfaction in production of goods and services
What are decisions?
Aspects of choice and how we solve problems
