Economic Concepts Revision U1 AOS 1 Flashcards
microeconomics
Microeconomics studies the behaviour and performance of individual consumers, businesses or markets in the economy
macroeconomics
Macroeconomics studies the overall behaviour and performance of the whole nation or global economy
microeconomics key points
- the operations of a particular firm
- the nature of a single industry
- the output, employment and prices in an individual market
macroeconomics key points
- the total value of a nations spending
- the total value of a nations production
- the nation’s level of unemployment
- the nation’s inflation rate
what’s the difference between micro and macroeconomics
micro
- market
- effect of prices of goods
- labour market
- consumer behaviour
- supply of goods
macro
- GDP
- inflation
- employment & unemployment
- aggregate & demand
- capacity of economy
decide if these are micro or macro related issues
1. excise tax on petrol is halved during 2022 to ease cost of living pressures
2. Aus’s rate of inflation soar’s above 5% during 2022
3. young investors are demanding crypto currencies in the hope of becoming rich
4. the war in Ukraine caused gas and oil shortages in 2022
5. the unemployment rate dropped below 4% during 2022
what is positive economic analysis
Analysis of economic issues that can be proved or disproved based on hard fact or evidence
“If…then..else…”
what is normative economic analysis
Analysis of economic issues that are subjective or opinionated views of what is happening in an issue or one thinks should be done about it
Used when it’s hard to find fact/evidence
“It should..”
compare positive vs normative analysis
positive
- free of personal opinion
- based on fact and evidence
- can be proved/disproved
normative
- not based on tested fact
- based on personal opinion
- can be proved or disproved
decide whether these statements are positive or normative
- company tax cuts should increase in economic activity
- the Aus govt is spending an insufficient amount on education
- Aus is one of the wealthiest countries in the world
- Aus’s minimum wages are too low
- legalising marijuana for medical purposes will increase the rate of illegal drug use
- An oversupply of crude oil contributed to lower crude oil prices over 2015- 16
what are goods + egs
Goods are material or physical objects capable of satisfying our needs and wants.
They may be of a lasting form (durables) or they may be single-use items.
what are services + egs
Services are non-material performances or actions produced by people capable of satisfying our needs and wants.
need
A need is a good/service essential for survival and function.
want
A want is something desired that is not essential for survival and function.
decide whether these are needs or wants
house
television
mobile phone
motor vehicle
train services
food and water
underwear
dinner suit
digital tablet
what goods and services would meet the needs and wants
wifi
battery
friends
family
food
water
shelter
air
protection etc
what does economics involve
Economics involves making decisions on transactions with the goal to satisfy ones needs and wants
production
what is produced
income
what is earned
expenditure
what is spent
What might be transacted between production, income and expenditure?
flow of income is created. This income, which flows to households from firms, is then spent by the households on the goods and services that were produced, and as they spend, a flow of spending
How do transactions in an economy achieve the goal of satisfying needs and wants?
the transactions in an economy achieve the goal of satisfying needs and wants because these transactions lead to the production of resources that households recieve income from and then are able to spend on goods and servicies that satisfy their needs and wants.
decide whether each of these is a factor of production, income or expenditure

economics definition
Economics is the study of
how we choose to use limited resources
in ways that best
satisfy our basic needs
and unlimited wants.
what are resources
Resources: (aka factors of production) are inputs used to produce goods & services
land resources
natural
labour resources
effort that humans/workforce contribute to
capitol resources
equipment/buildings used to produce goods and services eg machinery, tools
Entrepreneurship
Entrepreneurship is actually another factor of production, but is not covered in the study design.
Why is a resource like money or time not considered a factor of production?
Money (how much $) is just a medium used for exchange and not directly involved with production
decide if these resources are land, labour or capitol resources
tractor
computer used at home
teacher
mineral sands
computer used at Aus post
great barrier reef
a computer programmer
the PM of Aus
motor car used as a taxi
farmland
what is relative scarcity
Relative Scarcity is
where needs and wants for goods/services > resources available
what are examples of resources that are scarce
Limited oil reserves
Shortage of skilled labor in a tech industry
Limited investment capital available for tech startups
Limited availability of high-tech materials
info on earth overshoot day
Earth Overshoot Day marks the date when humanity’s demand for ecological resources and services in a given year exceeds what Earth can regenerate in that year.
what is opportunity cost + a GOOD example
Opportunity Cost is the next best alternative/option given up (or “forgone”) in order to meet prioritised needs/wants
meaning as our resources are limited, if we use a resource in one thing, then we cannot use/reallocate that same resource to another.
eg If you spend time watching TV, you cannot spend that time studying.
Here, time is the resource.
The choice is Entertainment.
The Opportunity Cost is less studying.
i.e I lost the opportunity to study because I chose to allocate the time for entertainment instead.
what are trade offs + egs
Trade-offs are about sacrificing one thing for another.
Similar but broader in scope than opportunity cost
Sacrificing as opposed to reallocating resources
Eg, saving for the future instead of spending on things now (Sacrificing happiness for security)
opportunity cost vs trade offs + comparison eg
opportunity cost refers to what a person could have done with what was sacrificed
refers to the next valuable opportunity
trade off - describes what is sacrificed to get something else
refers to two opportunities or more with choice
Opportunity Cost: what next best alternative did you give up to get what you want?
It cost me the opportunity to produce 1 fish, for every 1 banana
Trade off: the giving up/sacrifice of one thing in return for something else?
I sacrificed producing fish so I can produce bananas
what is a CBA?
Cost-Benefit Analysis: Value-based decision-making that involves comparing the cost against its expected reward
why do governments often use a CBA
Governments and firms often use a cost-benefit analysis to help them decide where resources should be allocated.
what is a benefit cost ratio
what is a good ratio/bad ratio + formula
Benefit to cost ratio (BCR): Divide total benefits by total costs.
BCR > 1.0 = Net benefit = good ☺
BCR < 1.0 = Net cost = bad ☹
eg of CBA
Create and share you own Cost-Benefit Analysis of one of the following:
To do all your homework vs not
To do subject X vs subject Y
To buy X vs Y
To study at uni what your parents
want vs what you really want
Choose you own to analyse
Calculate the BCR. What’s the verdict?
decision making and its examples
making decisions based on prioritised needs and wants
eg buying the car or saving for a house
why maximise production
Scarce resources are used in ways that maximise a nations productive output of goods and services
If the maximum output of goods/services are being produced then it is more likely our needs and wants will be met
i.e this will improve living standards
We also want to minimise the opportunity cost/trade-offs of the decisions that we make
Productive or technical efficiency:
Productive or technical efficiency: productivity is maximised through minimum inputs (resources) and maximum output(at productive capacity)
Allocative efficiency
Allocative efficiency: scarce resources are directed into producing goods/services that help more satisfy society’s needs and wants over other goods/services (opportunity cost)
is productive always = to profitable
productive is not always most profitable
what is a PPF + what do the different parts of a PPF tell us? + egs
Also known as PPD (Production Possibilities Diagram)
A tool used to highlight concepts such as:
Opportunity cost: What options are missed out
Productive capacity: how much a nation/firm can produce
Productive efficiency: How efficient are we producing goods/services with the given resources
what assumptions does a PPF graph rely on
Only two goods/services are produced in the economy
All resources can be used in the production of either good
Each unit of resource, goods and services are worth the same value
At any given point in time, the economy’s productive capacity is limited by the curve
what do the different points on a PPF tell us
Any points along the line shows the productive capacity of different maximum combinations of goods and services produced where all resources are fully used
Therefore, on the PPD, any point on the line is productively efficient
Any point under the line however means resources are under-utilised
Any point outside the line means a nation’s resources are over-utilised
What if Productive Capacity isn’t enough to meet needs?
how do we increase productive capacity
We could try to
increase quantity (volume)
and/or
improve quality (effectiveness)
of resources available.
What does increased productive capacity look like on the PPF?
The curve shifts outwards
