Supply Flashcards
Supply?
The quantity of a product a producer is willing and able to supply onto the market at a given price in a given time period.
What is the equation for total revenue?
Price of good/service multiplied by quantity sold
what is the law of supply?
as prices of a product rise, producers expand supply to the market.
what does a supply curve show?
relationship between price and how much a firm is willing and able to sell.
why does the supply curve slop upwards?
- the profit motive
when market price rises following an increase in demand, it becomes more profitable for firms to increase output - production and costs
when output expands, firms production costs rise so higher prices are needed to cover costs- effects of diminishing returns - new entrants into market
higher prices may create incentive for other businesses to enter market= increase in total supply.
what is market supply?
total supply brought to the market at each price
to calculate, add the individual supply schedules
what shifts supply curve?
o P- Productivity. Higher productivity causes an outward shift in supply, because average costs for the firm fall.
o I- Indirect taxes. Inward shift in supply.
o N- Number of firms. The more firms there are, the larger the supply.
o T- Technology. More advanced the technology causes an outward shift in supply.
o S- Subsidies. Subsidies cause an outward shift in supply.
o W- Weather. This is particularly for agricultural produce. Favourable conditions will increase supply.
o C- Costs of production. If costs of production fall, the firm can afford to supply more. If costs rise, such as with higher wages, there will be an inward shift in
supply.
what is competitive supply?
goods/services in competitive supply are alternative products that a business can make with its FOP
what is price elasticity of supply?
PES measures relationship between change in quantity supplied and a change in market price.
The price elasticity of supply is the responsiveness of a change in supply to a change in price. T
elastic supply and producers
PES is greater than 1
producers can increase output without rise in cost or or a time delay.
inelastic supply and producers
PES is less than 1
firms find it hard to change production in a given time period.
what is joint supply?
This is when increasing the supply of one good causes an increase or decrease in the supply of another good. For example, producing more lamb will increase the supply of wool.
perfectly inelastic supply
A perfectly inelastic supply has PES = 0. Supply is fixed, so if there is a change in demand, it cannot be met easily.
perfectly elastic supply
Supply is perfectly elastic when PES = infinity. Any quantity demanded can be met without changing price
what are factors that affect PES?
time scale spare capacity level of stocks how substitutable factors are barriers to entry to the market
