1.2 Supply Flashcards
what is supply?
when a producer is willing and able to sell a good
draw a supply curve
as the price of a good increases, the profit that can be made for the producer incraeses and so they have more of an incentive to supply a larger quantity
define supply
the quanitity of a good or service that firms are willing to sell at a given price over a given time period
what are the assumptions of a supply curve?
- firms want to maximise profits
- doesn’t consider why the price increases
- just tells us what were to happen if price increases
what are the conditions of supply? (5)
- weather
- technology
- cost of production (profit & incentive, cannot afford)
- number of suppliers
- productivity
shift inwards/ outwards
what is excess supply/ surplus?
the gap between supply and demand at a given price
* producers will decrease their prices to get eliminate excess supply
* (when price is above equalibrium price)
when is there equilibrium?
quantity supplied = quantity demanded
supply and demand meet
what is the excess supply/demand at
* 70p
* 40p
* 50p
incease in supply
- s1 to s2
- leading to p1 to p2 (decrease in price)
- because Q1 to Q2 (quantity supplied increased)
what is price elasticity of supply?
a measure of the responsivness of quantity supplied to a change in price
what is the formula for price elasticty of supply?
PES = %change in quantity supplied / %change in in price
%ΔQs/ %ΔP
what is the range of PES elastic, inelastic, unitary elastic?
- Elastic: 1- ∞
- Inelastic: 0-1
- unitary elastic =1
what do the elastic and inelastic supply curves look like?
what are the five main factors which effect elasticity of supply?
- time
- state of the economy
- availibilty of factors of production
- spare capacity
- stockpile& perishability
TEASS
what does spare capacity mean?
how much capacity is there that is not being used
