Theme 1 Flashcards
What is an economic model?
A simplified version of reality designed to help understand the causes and effects of economic events.
What is a positive statement?
A statement which can be supported or refuted by evidence.
What is the economic problem?
There are scarce (finite) resources and unlimited wants.
What are renewable and non-renewable resources?
Renewable resources can be exploited over and over again (e.g. a forest); non-renewable resources can only be exploited once (e.g. coal).
What is a PPF?
A production possibility frontier shows the maximum possible output of two goods assuming that all resources are used efficiently.
What does ceteris paribus mean?
The assumption that whilst the effects of a change in one variable are being investigated, all other variables are kept constant.
What is a normative statement?
A statement that cannot be supported or refuted because it is a value judgement.
What are the factors of production?
Resources that are inputs into the production process. They are:
* Labour - the workforce of an economy
* Capital - manufactured aids to production (e.g. factories, tools)
* Land - the land itself but also natural resources
* Enterprise - individuals who organise the other 3 factors of production.
What is meant by opportunity cost?
The benefits forgone of the next best alternative.
How can a PPF show the maximum productive potential of an economy?
The maximum productive potential of an economy is any point on the PPF (e.g. X or Y).
How can a PPF show opportunity cost?
With a movement along the PPF
For example, moving from point X to Y indicates that the opportunity cost of producing 3 more consumer goods is one capital good.
What points on a PPF indicate inefficiency, efficiency, and unattainability?
Inefficient - inside the PPF, e.g. W
Efficient - on the PPF, e.g. X or Y
Unattainable - beyond the PPF, e.g. Z
Producing at an inefficient point indicates that some resources are unemployed. For instance, at point W, there may be unemployed workers and unused factories.
What is meant by specialisation?
When individuals, firms, or nations focus production on a narrow range of goods or services.
What is division of labour?
Specialisation by workers who perform different tasks at different stages of the production process.
How can a PPF show economic growth?
By shifting outwards
This can occur due to improvements in the quality or quantity of factors of production, such as education, training, technological advancements, immigration, and investment.
What causes a PPF to shift left?
A decline in resources, such as those destroyed in a war or natural disaster.
How does the allocation of resources affect economic growth?
Using more resources to produce capital goods will increase future factors of production, shifting the PPC outwards.
What are the advantages of the division of labour?
- Workers become very skilled and productive at one task
- Increases output
- Reduces unit costs
Less time spent on making each good contributes to these advantages.
What is a disadvantage of the division of labour?
Boring for workers
Additional disadvantage includes higher unemployment due to machines replacing workers.
What are the functions of money?
- Medium of exchange
- A measure of value
- A store of value
- A method of deferred payment
Examples include purchasing goods, measuring value through prices, saving for future purchases, and taking out loans.
What does ‘allocation of resources’ mean?
Use of factors of production
It refers to what the economy will use its resources for, such as making tanks, vaccines, or smartphones.
What is the link between specialisation and markets?
Specialisation leads to production for sale in markets
Individuals who specialise in one product wish to sell it to buy other products they want.
