1.3.2 Supply Flashcards
Supply
The quantity of a good or service that a producer is willing and able to supply onto the market at a given price in a given time period
Supply curve
A graphical representation of the relationship between quantity supplied and price, for all suppliers in the market
what is quantity supplied
Quantity supplied is the amount sellers are willing and able to offer for sale at a single price
The short run
The time period in which the quantity of at least one component in production cannot be changed
The long run
The time period in which the quantities of all the factors of production can be changed
supply and producers/entrepreneurs (3)
- In both supply and demand, the market forces impact the quantity of a product supplied in the marketplace.
- Producers have mixed objectives:
The ability to earn profits and income has an influence on the choices made by all suppliers. - Potential profits provide an incentive to supply
Describe the supply curve
- When plotting supply curves, quantity is on the x-axis and price is on the y-axis
–> graph has a POSITIVE correlation as price and quantity supplied have PROPORTIONAL RELATIONSHIP
–> Supply curves usually slope upwards from left to right, showing that less will be supplied at a low price, and more at a higher price
what happens when the market price of a product increases (3)
- producers expand their supply onto the market, and supply more
- Even if their costs of production increase when producing more, a higher price increases revenue from sales
- If the revenue increase is greater than the cost increase, there is potential for higher profit → this incentive attracts extra supply (eg, more supply, more firms entering the market)
how does supply cycles work
- When something is just newly produced its price is high and the quantity supplied is high too
- In the long term, the price will probably lower and profitability will lower
- Eventually price and output are likely to get to a steadier level
how do the short run and long run relate to movements along the supply curve
- In the short run, a price change causes a move along the supply curve
- In the long run, a move to a new supply curve is possible, but a shift in supply is not due to price change, but another factor
name 5 factors other than price that can affect quantity supplied
- changes in costs of production
- introduction of new technology
- indirect taxes and subsidies
- change in the number of firms in an industry
- external shocks
- efficiency
Costs of production and supply
- If costs increases (and nothing else changes), supplying the market becomes less profitable –> Profit decrease = can purchase less raw materials, pay less workers etc.
- Producers want a higher price to supply any quantity, so the supply curve is likely to move up and left
State of technology and supply
- Even though the latest tech is expensive, its success normally depends on reducing cost per unit
- Successful, new tech will shift the supply curve to the right → an important component of economic growth
- this is because new tech can make production efficient, increasing supply
indirect tax + subsidies and supply
- Intention can be to reduce sales, to raise tax revenue, or both
- The effect of an indirect tax on a product will be to increase the price to the customer (ie cigarettes, alcohol, sugar)
- Many businesses feel the impact of taxes on fuel, but farmers have benefitted from subsidies offsetting some costs
Subsidiaries: where the government encourages production by making materials cheaper or giving money/grants
Changes in the number of firms and supply
- A profitable market attracts more producers (entry) → more supply
- If a product becomes unprofitable firms will leave the industry and supply will decrease
