Nature of economics Flashcards
What do economists need to do
Make key assumptions
Define ceteris paribus
The assumption that other factors remain equal or constant so that nothing else changes
What is a key assumption that economists need to make
Assuming that events occur with ceteris paribus
Why is the assumption that other factors remain equal need
Economists cannot test models in scientifically controlled laboratory conditions
What is the impact of economists unable to conduct scientific experiments
Economists need to use real-life scenarios to devise models as an alternative in order to form assumptions
Define economics
The allocation of scarce resources to provide for unlimited human wants
Define positive statements(will/is)
Value-free statements based on facts which can be tested as true or false
Define normative statements
Statements concerned with value judgements with a non-scientific approach
Role of value judgements in influencing economic decision making
Personal preferences and subjective assessment can underpin decisions made by consumers and producers
Example of value judgements influencing consumers
A highly cautious consumer may prefer to save their income in a pension fund rather than increase spending on goods
Example of value judgements influencing firms
A producer prone to taking high risks may prefer to spend cash reserves on developing new goods rather than saving reserves
Role of value judgements in influencing government policy
A government may prefer to cut income tax rather than increase expenditure on healthcare/provision if they have a preference for free market forces
What is the basic economic problem based on
Scarcity
Define scarcity
the idea that because there are finite resources compared to infinite wants, choices must be made about how to use those resources
Why does scarcity arise
When there are insufficient resources to provide for everyone’s wants
Why does scarcity occur in all economies
Resources are finite compared to human material wants
Where is scarcity obvious in
Countries that face famine or drought where insufficient food or water is available to meet all needs
Why can scarcity exist in wealthy countries
Not all human material wants can be satisfied
Why does scarcity mean for us
We have to make choices over the use of our limited resources to provide for our material wants
What decisions must be made due to scarcity
Crucial decisions must be made over what, how and for whom to produce
Who faces these decisions
Consumers, producers and the government
What happens once a decision has been made about what to use a resource for
An opportunity cost arises
Define opportunity cost(OC)
The value of the next best alternative forgone
Who faces opportunity cost
Consumers, producers and the government
