Questions from this subtopic
Each one with the model answer underneath.
- 1
What is measured on each axis of a supply curve diagram?
Model answer
Price is measured on the vertical axis and quantity supplied per period of time on the horizontal axis.
- 2
Define supply.
Model answer
The quantity of a good that producers are willing and able to offer for sale at a given price over a given period.
- 3
Describe the shape of a typical supply curve and explain why it slopes that way.
Model answer
It slopes upwards from left to right, because a higher price makes production more profitable and covers the rising marginal cost of producing extra units.
- 4
How does the profit motive produce an upward-sloping supply curve?
Model answer
At a higher price each unit sold earns more, so existing firms find it worthwhile to expand output and new firms are drawn into the market.
- 5
How is market supply derived from the supply curves of individual firms?
Model answer
By adding the quantity each firm supplies at every price, that is, by horizontal summation of the individual curves.
- 6
Why is a market supply curve generally flatter than that of a single firm?
Model answer
Because the output of every firm is added at each price, total quantity responds far more to a given price change.
