Supply Flashcards
Define supply

Why does supply slope upwards
Because producers are willing to produce more at a higher price as they profit maximise
PES definition
A measure of the responsiveness of quantity supplied in response to a change in price
PES formula
PES = % change in quantity supplied / % change in price
All PES’s are _________
Positive
A PES greater than 1 is ___________
Elastic
A PES between 0 and 1 is ___________
Inelastic
A PES is greater than 1 if change in quantity supplied is __________ than change in price
Greater
Unitary elastic supply = _____ - both % change in qs and % change in price are ________
1
Equal
Factors which influence PES
TEASS
- Time period
- Economy
- Availability of factors of production
- Spare capacity
- Stockpiles
Lots of spare capacity = ___________
Elastic - More room to increase output
Less spare capacity = ___________
Inelastic - less room to increase output
High availability of factors of production = __________
Elastic
Low availability of factors of production = __________
Inelastic
Economy in good state = __________
Inelastic
