- A producer of e-cars lowers the price which results in an increase in total revenue. Therefore
- these e-cars are normal goods
- these e-cars are inferior goods
- the demand for these e-cars is elastic
- the demand for these e-cars is inelastic

- A producer of bycicles lowers the price, but total revenue remains unchanged. This means that
- the demand for these bycicles is inelastic
- the demand for these bycicles is elastic
- the demand for these bycicles is perfectly elastic
- the demand for these bycicles is unit elastic

- The cross-price elasticity of demand for the goods A and B is 0.5. If the price of A increases, then
- the quantity demanded for B increases, the goods being complements
- the quantity demanded for B decreases, the goods being substitutes
- the quantity demanded for B increases, the goods being substitutes
- the quantity demanded for B decreases, the goods being complements

- In which case is the demand elastic?
- when the price elasticity of demand is greater than 1
- when the price elasticity of demand is less than 1
- when the price elasticity of demand is 1
- when the price elasticity of demand is 0

- If the demand for a good is elastic, then a 6 % decrease in the price causes
- an increase in the quantity demanded of exactly 6 %
- an increase in the quantity demanded of more than 6 %
- no change in the quantity demanded
- an increase in the quantity demanded of less than 6 %

- If a price decreases, total revenue will
- increase if the demand is elastic
- in any case decrease
- in any case increase
- increase if the demand is inelastic

- Along a linear demand curve, the price elasticity of demand
- is small at high prices
- is always equal to 1
- is always 0
- is small at low prices

- Oranges are normal goods if the ......... for oranges is ..........
- price elasticity of demand; negative
- income elasticity of demand; positive
- income elasticity of demand; negative
- price elasticity of demand; positive

- If two goods have a negative cross-price elasticity of demand, then these are
- normal goods
- complements
- substitutes
- luxury goods

- If a 20 % decrease in the price of good A causes a 10 % increase in the quantity demanded of good B, then the cross-price elasticity of demand between the two goods is
- - 0.5
- - 2.0
- + 2.0
- + 0.8

- If the supply is perfectly inelastic, then a 3 % increase in the price causes .......... in the quantity supplied.
- less than a 3 % increase
- no change
- more than a 3 % increase

- the demand is elastic
- the demand is inelastic
- the demand is unit elastic
- the demand is perfectly elastic

- If the price of a good rises by 5 %, then the quantity demanded falls from 100 to 91. Therefore
- the price elasticity of demand is 0
- the demand is inelastic
- the demand is elastic
- it is a normal good
