LS8 and LS9 - Demand and Supply Flashcards
Demand
Demand is the quantity of goods purchased at a given price over a certain time period
Movements on a demand curve are caused by…
What is an extension and contraction
These are caused by changes within price level.
An increase in price level would cause an extension.
A decrease in price level would result in a contraction.
Substitute Goods
Two alternative products that can be used for the same purpose
Complimentary Goods
These are goods which are used together
Shifts in Demand
Shifts in demand are caused by changes in PASIFIC
Population - When population increases, demand increases
Advertising - Successful advertising would result in an increase in demand
Substitute goods - An increase in the price of iPhone’s would result in a decrease in demand and then an increase in demand of Samsung phones, a substitute good
Income - A rise in real income would increase demand as people are more able to afford products
Fashion/Preferences - A new fashion would result in an increase in demand of those goods in particular
Interest rates - As interest rates rise, borrowing becomes more expensive and so there are falls in demand of houses, cars and other expensive goods.
Consumer Tastes - Changes in consumer tastes means that the demand for a good that is no longer in taste has a fall in demand. A good that is now in taste/fashion has an increase in demand
Supply
The ability and willingness to provide a good or service at a given price at a given time
Movements on the Supply Curve
These are as a result of supply levels.
As there is an increase in supply, there is an extension on the graph
As there is a decrease in supply, there is a contraction on the graph
Diminishing law of marginal utility
The satisfaction derived from the consumption of an additional unit of a good will decrease as more of a good is consumed
Shifts in Supply
Shifts in supply are caused by changes in the costs of production. The factors that cause shifts in supply are PINTSWC
Productivity
Indirect tax is a tax on goods and services which are costs that the firm would have to cover. This means the costs of production increases
Number of firms. The higher the number of firms in the market, the higher the supply
Technological advancements would mean that the supply shifts right
Subsidies lower the costs of production meaning that supply would shift to the right
Weather may affect the crops and therefore the supply of a good
Costs of production. Transport, Labour, Oil, Raw material
