Causes for Change in Demand?

Consumer Income Consumer Taste Substitutes Complements Change in Expectations Number of Consumers

Consumer Income If consumer’s incomes increase they

are able and willing to buy more products

If consumer’s incomes decrease they are less likely to buy products.

Ex.: When our unemployment rate is low, our economy strives.

Consumer Tastes Advertising, news reports, fashion

trends, and changes in the season have an affect on demand

Ex: In the month of October, people tend to buy items that are pink…

Substitutes Products that can be used in place of

other products.

Ex.: when the price of Coca-Cola goes up, the demand for Pepsi goes up.

Complements An item that increases the use of

another product.

Ex.: When the price of blu-ray players goes down, consumers buy more blu-ray players and blu-rays.

Change in Expectation Change in what people expect

in the future.

Ex.: the iPhone 5 was announced in June. That caused the demand for iPhone 4/4s to go down.

Ex.: consumers might wait until Black Friday to buy a product they know will be on sale.

Number of Consumers An increase in the number of

consumers will change the demand for an item.
