What is supply?
The number of goods/services a business is willing to supply
What is the relationship between supply and price?
There is a direct relationship:
- As price increases the quantity supplied increases too
- As price decreases, the quantity supplied decreases too
What direction does the supply curve go?
What does a change in price cause?
-a movement along the supply curve
What do non-price factors affecting supply cause?
-a shift in the supply curve left or right
What are the non-price factors affecting supply?
1) Changes in cost of production
2) New technology
3) Indirect taxes
4) Government subsides
5) external shocks
How do changes in the cost of production affect supply?
An increase in the cost of production makes it more expensive to produce each unit, so a business will be able to produce fewer units at that given price
How do external shocks affect supply?
-An unexpected event can change supply
-The outbreak of Covid-19 caused many hotels, bars and restaurants to close down
This shifted the supply curves for hotels, bars and restaurants to the left
1a) What are government subsidies?
1b) And how do they affect supply?
1a) A producer subsidy (financial aid) given by the government to businesses will reduce the cost of production
1b) A subsidy to the largest battery producer in the UK lowers the cost of production for electric car manufacturers
This has shifted the supply curve for electric vehicles to the right
How does new technology affect supply?
-advances in technology will lead to lower costs of production, and businesses will be able to produce more units at a given price
How do indirect taxes affect supply?
-The government increases indirect taxes on businesses, which causes an increase in the cost of production, as firms have to pay extra costs, meaning they can produce less at a given price
-The rate of VAT increased from 17.5% to 20% in the UK in 2011
This shifted the supply curves for all businesses to the left
What are indirect taxes?
-taxes on a businesses goods and services and not on its income/profits
-e.g VAT
