What is economics
The allocation of scarce resources to provide for unlimited human wants
How is economics a social science
Economics is a social science, which means it is concerned with the study of human behaviour. It investigates how scarce resources are allocated to provide for unlimited human wants.
Why do economists make assumptions
Economists develop models which attempt to simplify and improve our understanding of how consumers and producers behave.
These models include assumptions eg. Consumers aim to maximise profits satisfaction or utility when spending their income.
Producers may aim to maximise profits
Simply, what is ceteris parabus
All other things being equal
What is ceteris paribus
It means all other things being equal or all other things remaining the same.
Used in models to show the effects of one change on something
What is positive economics
Positive economics is concerned with facts and is value free. Positive statements can be tested as true or false by referring to the facts.
What is a positive economics statement
Based on facts which can be tested as true or false and are value free
What is normative economics
Concerned with value judgements and is a non scientific approach to the discipline
Normative economics statement
Based on value judgements which cannot be tested as true or false.
What is scarcity
There are finite resources compared to infinite human wants, so choices have to be made about how to use those resources.
What is the economic problem
The economic problem is based on scarcity. Scarcity arises because there are insufficient resources to provide for everyone’s wants.
Some crucial decisions have to be made over what, how and for whom to produce. These decisions are faced by consumers, producers and the government. Once a decision has been made about what to use a resource for, opportunity cost arises.
Simply what is opportunity cost
The value of the next best alternative forgone.
What are resources/factors of production
Resources/ factors of production, are inputs used in the production of goods and services. They are finite and can be classified into 4 types, land, labour, capital and enterprise.
What are the factors of production
Land, labour, capital and enterprise.
What is a renewable resource
Is one whose stock level can be replenished naturally over a period of time. Such resources include solar energy, wind power, tidal flower, fish, timber and soil.
However, renewable resources may decline over time if they are consumed at a faster rate than the environment can replenish them. They require careful management, to avoid such things as deforestation and soil erosion.
What is a non renewable resource
A non renewable resource is one whose stock level decreases over time as it is consumed. These resources include fossil fuels such as coal, oil and gas. They also include commodities such as steel, copper and aluminium. It is possible to reduce the rate of decline of non-renewable resources through recycling and the development of substitutes. The price mechanism also has a role to play in reducing the rate of consumption via higher prices
Was is a renewable resource simply
A resource whose stock level can be replenished naturally over a period of time
What is a non renewable resource simply
A resource whose stock level decreases over time as it is consumed.
What does a production possibility frontier
A PPF shows the maximum potential level of output for two goods or services that an economy can achieve when all its resources are fully and efficiently employed, given the level of technology available.
It can be used to illustrate scarcity and opportunity cost.
What can a PPF illustrate
Scarcity and opportunity cost.
What are the Axis on a typical PPF
Capital goods output on y axis
Consumer goods output on x axis
What are consumer goods
Consumer goods directly provide satisfaction or utility to consumers. They are wanted for their own sake rather for what they produce. Examples include clothing, food, drink, a holiday and iPhones.
What are capital goods
Capital goods are used to produce more consumer goods and services. Generally, they provide satisfaction to consumers indirectly. Examples include machinery, office blocks, training of workers and factories.
Some what is a consumer good
A good such as a chocolate bar, that directly provides utility to consumers. It is wanted for the satisfaction it gives.
