Supply elasticity Flashcards
What is price elasticity of supply?
how responsive the quantity supplied is for a good or service when price changes.
What are the determinants of PES?
- Time
- Mobility of factors of production
- Unused capacity
- Ability to store
- Rate at which costs increase
Explain the determinant ‘time’
Given enough time, most goods are supply elastic as factories can be built/upgraded to provide for more supply. More time therefore increases PES.
Explain the determinant ‘mobility of factors of production’
If it is easy to employ more people, buy more land, or build new capital, it is easier to supply more if needed. More mobility therefore increases PES.
Explain the determinant ‘unused capacity’
If factories have unused machines, it is quite easy to increase supply. More spare capacity therefore increases PES.
Explain the determinant ‘ability to store’
If the good is easy to store, excess supply can be stored for the future, in case the price increases. Better ability to store therefore increases PES.
Explain the determinant ‘rate at which costs increase’
If it costs the firm a lot to make additional goods, it will hesitate before producing/supplying more. Higher additional costs therefore decreases PES.
Why is the PES for primary commodities generally lower than manufactured goods?
- takes longer to produce
- harder to store
- low mobility of factors of production (harder to get new land than buying machinery)
