market price reduction
Name the five main influences on the position of the supply curve.
- production costs
- taxes and subsidies
- price of related goods
- firm expectations about future prices
- number of firms operating in the market
What would be effect on supply curve of an increase in VAT and why?
shift to left, as for a given market price the supplier will receive less
What would be the effect on the supply curve of an increase in costs?
shift to left
What would be the effect on the supply curve of the introduction of a subsidy to suppliers and why?
shift to right, as is equivalent to reduction in costs
Why might an increase in the price of a related good affect the supply curve?
- if it can be produced using same factors of production then more profitable for supplier to change to supplying the related good, or
- if it’s a by-product of same production process (eg wool and mutton) so producer will produce more of both
If higher price expected in future, what might this do to supply?
supply reduces, as firms choose to hold some stock back to sell in future
Define cartel.
an agreement between forms in market on price and ouput with intention of maximising joint profits
What does price elasticity of supply measure?
sensitity of quantity of a good or service supplied to a change in price of that good or service
What’s the formula for price elasticity of supply?
PES = % change in quantity supplied
/ % change in price
What values can PES take if supply is price elastic?
PES > 1
