(117 cards)
What is meant by the term Ceteris Paribus?
All other things remaining the same.
What is meant by Positive Statements?
Are statements which can be proven to be true or false, they are supported by statements
Even if a statements cannot be proved immediately but can be proven in the future, are these statements positive ones?
YES
What is meant by the term Normative Statements?
Are opinions which cannot be supported or refuted.
What is the scientific method at its most basic level?
- Scientist puts forward a hypothesis with is capable of being disapproved
- Gathers evidence to support or refute the theory
- Accepts, modifies or refutes the theory
What is Economics the study of?
Is the scientific study of ownership, use, and exchange of scarce resources
Why is Economics regarded as a Social science?
Because it uses scientific methods to build theories that can help explain the behaviour of individuals.
What does Economics attempt to explain?
Explain economic behaviour, which arises when scarce resources are used
How do economists gather data to accept or refute a hypothesis?
Gather data in the ordinary everyday world where many variables are changing over any given time period.
Why can it be argued that economics is not a science?
Because it studies human behaviour and human behaviour cannot be reduced to scientific laws
Why is the study of groups better than the study of individuals?
Because the behaviour of groups is far more predictable than individuals
What is the difference between Economic Theories and Economic Models?
- Theories are expressed in words
- Models are often more precise as they are expressed in mathematical terms
Why are theories and models used in science?
- Because we want to know why something is as it is.
What is one criticism of economics?
Economic models and theories are unrealistic
What is meant by Simplification of models?
Implies that some factors have been included in the model and some have been omitted.
How does making assumptions help scientists?
Allows scientists to simplify a problem to make it manageable to solve
What is the link between Positive and Normative Statements ?
Economists usually start off with a Normative statement then use models and theories to build a positive statements from the Normative one.
What are some words which are usually included in Normative Statements?
- Should
- Ought
Is the statement ‘Inflation should be brought down’ a positive or Normative statement?
Normative
Is the statement ‘Inflation should reach 5% by the end of the year’ a positive or Normative statement?
Positive
What is meant by Normative Economics?
Determines what is desired in the economy (‘what ought to be?’)
What is meant by Positive Economics?
What is actually happening in the economy (‘what is’)
What does economics investigate?
How scarce resources are allocated to provide for unlimited human wants
Why is Ceteris Paribus needed?
Because economists cannot test models in scientifically controlled laboratory conditions
