MICRO - LS9 - Supply Flashcards
Revenue definition
The income that a government (through tax) or company (through sales) receives
Total revenue equation
Price x quantity
What do firms do in a market
Supply goods and services
Supply definition
The quantity of a good/service that firms are willing to sell at a given price over a given time period
What does law of supply state
Ceteris Paribus:
- as price of good increases, quantity supplied increases
- as price of good decreases, quantity supplied decreases
What does increase in price result in
- extension/expansion in supply shown through movement along supply curve
What does a decrease in price result in
- a contraction in supply shown as a movement
What does supply diagram assume
- firms are motivated to produce by profit
- the cost of producing a unit increases as output increases
The conditions of supply
- costs of production
- price of other goods
- no of firms in the market
- weather
- technology
- goals of supplier
- government legislation
- taxes and subsidies
- producer cartels
Costs of production
- if price increases but selling price stays the same less profits
- will put up price in order to avoid making a loss and so less is supplied at each price, meaning the supply curve will shift to the left
- If they have a decrease in their costs, then it will shift to the right
Price of other goods
- Joint supply is where the production of one good automatically causes the production of another goods e.g. the production of beef automatically produces leather
- Therefore, if the price of beef rises, farmers will slaughter their cows and so will get more leather, causing a shift to the right and an increase in supply
- Competitive supply is where the production of one good prevents the supply of another e.g. if the farmer kills his cows, he can no longer produce the milk
- Therefore, the rise in the price of beef may cause a decrease in the supply of milk and a shift to the left.
Weather
- For some goods, particularly agricultural goods, the supply is dependent on weather e.g. if the weather is good, more wheat will be produced so the curve will shift to the right. If the weather is bad, the producers won’t be able to supply as much wheat and so it will shift to the left.
Technology
- If new technology is introduced then it will lead to a fall in production costs as there is higher productive efficiency
- This will encourage firms to lower prices or produce more goods for the same price and so the curve will shift to the right
Goals of supplier
- If a supplier is motivated by helping society and providing a service, they may increase supply even when that doesn’t provide extra profit
Government legislation
- If the government passes laws that mean more cars have to have catalytic converters, supply of cars with catalytic converters will increase
- High levels of regulation may increase costs and so decrease supply
