Ceteris paribus and market equilibrium and disequilibrium
- 3 things to know
- Component 01
Overview
Recall questions on the ceteris paribus assumption, market equilibrium, excess demand and excess supply, and how the price mechanism removes disequilibrium.
What you need to know
Answer each one before you reveal it.
How does the market eliminate excess supply?
What does ceteris paribus mean?
Questions from this subtopic
Each one with the model answer underneath.
- 1
What does ceteris paribus mean?
Model answer
All other things being equal, that is, all other influences are assumed to be held constant while one variable changes.
- 2
Why must the ceteris paribus assumption be made before a demand curve has any meaning?
Model answer
Without it the effect of a price change could not be separated from the simultaneous effects of income, tastes and other prices.
- 3
What is one weakness of relying on ceteris paribus?
Model answer
In the real world several variables change at once, so a prediction made by holding them constant may not be what is actually observed.
- 4
At market equilibrium, what is true of quantity demanded and quantity supplied?
Model answer
They are equal, so there is no pressure on price to change.
- 5
Where is the equilibrium found on a demand and supply diagram?
Model answer
At the intersection of the demand and supply curves, which gives the equilibrium price and equilibrium quantity.
- 6
What exists in the market at a price above equilibrium?
Model answer
Excess supply, shown by the horizontal gap between the supply and demand curves at that price.
