Q

Why does the supply curve slope upwards?

A

-Profit motive = the market place rises and becomes more profitable for businesses to increase their output
-Production and costs = when output expands, production costs rise and businesses up the price to cover the costs
-New entrants coming into the market = higher prices may encourage new businesses to enter the market which leads to an increase in supply

20
Q

What is price elasticity of demand?

A

Measures how responsive demand is to changes in price

21

% change in quantity / % change in price

22
Q

What is elastic demand?

A

When the % change in demand is higher than the % change in price, the amount people buy is sensitive to change
-They are goods people already want to buy

23
Q

-Luxury products
-Large income
-Customers have a long time to decide

24
Q

A

When the % change in demand is less than the % change in price, people will continue to buy it even if the price increases e.g milk

25
Q

What are the characteristics of inelastic demand?

A

-Fewer substitutes
-Necessities
-Smaller income
-People require the product now

26
Q

With inelastic demand when is revenue higher?

A

When price increases total revenue increases because consumers will continue to buy the product

27

When price falls the total revenue increases

28
Q

A

% change in demand / % change in income

-Consumer perceptions, businesses use promotional techniques to encourage customers to spend extra income on their goods
