This week in Econ class we learned about demand.
Demand is the willingness and ability for someone to pay for an item. If they can't pay for it or don't want it then the person does not have a demand for it. No matter how much they want it.
The amount of an item people are willing to buy at various prices can be shown on a demand schedule or a demand curve.
Both show the same information.
Demand schedules display the data in a chart.
Demand curves display the data in a graph
That is the only difference. Just how the info is shown.
The demand can shift though! Things outside of the price can affect how much people will buy of an item at any price.
There are 6 main things that can cause a shift in demand.
Income- People have more or less money to spend
Market size- Number of potential buyers change
Consumer tastes- Popularity increases demand
Consumer expectations- Possible future prices affect present buying
Substitute goods- Products are interchangeable
Complementary goods- Products are used together
For example: If people have less money to spend on products, then the demand curve will shift because they will be less willing to buy the same amount of a product at all of the prices.
