1.2.2 Supply Flashcards
Supply
The number of goods and services producers are willing and able to supply at any given price, over a period of time.
Relationship between price and quantity supplied
At higher prices, firms are more likely to cover their costs.
At this point the firm will be making a profit.
Firms are unlikely to produce, if they are making a loss, particularly in the long term.
The supply curve
A graphical representation of the relationship between quantity supplied and price, for all suppliers.
Price changes cause a movement along the curve.
Direct relationship.
Shifts in the supply curve
A change in any factor other than price e.g. new technology is shown by a shift in the supply curve.
An increase in supply can be seen by a shift in the supply curve to the right.
Determinants of supply
- Changing costs of production.
- Technology.
- Prices of other goods and services.
- Government policy.
- External shocks.
Changing costs of production
Costs of production are created by the price of inputs i.e. factors of production.
- If costs of production increase it will become more expensive to supply the product so firms will reduce output.
- If costs of production fall it will be cheaper to supply a product, there will be an increase in supply.
- Improvements in technology can help to reduce costs or production.
Technology
Technological progress has meant that firms can produce in a more efficient and cost effective way.
- Improved large scale machinery allows fixed costs to be spread over greater output making cost per unit cheaper.
- As technology improves, firms find it profitable to supply more.
Prices of other goods and services
Degree of competition in the market will impact on supply.
- As more firms enter the industry the supply curve will shift to the right causing increased supply.
- If a product becomes unprofitable businesses will leave, and supply decreases.
Government policy
Indirect taxes = Those placed on goods and services produced by individuals and firms.
Indirect taxes make it more expensive to produce so quantity supplied will decrease.
Subsidies = Finance provided to producers to encourage then to produce goods and services.
Subsidies will make it cheaper to produce a product, so quantity supplied will increase.
External shocks
Unexpected events that are outside of a businesses control but have a direct impact on the level of supply.
e.g. natural disasters, terrorist attacks, outbreak of disease.
