Income elasticity of demand measures:

a) how responsive quantity demanded is to changes in income.
b) how responsive quantity demanded is to changes in price.
c) how responsive income is to changes in education levels.
d) how responsive price is to changes in quantity demanded.

For the next part, suppose the income elasticity of demand for butter is 0.11. That means butter is:

a) a luxury good.
b) a normal good.
c) an inferior good.
d) a complementary good.
e) a substitute good.

Respuesta :

Answer:1) how responsive quantity demanded is to changes in income--A                  2) income elasticity of demand for butter is 0.11. That means butter is a luxury good---A

Explanation:

1) Income elasticity of demand refers to the responsiveness of the quantity demanded for a certain good to a change in income of consumers who purchase this good.The higher the income elasticity of a good,  the greater the consumers' response in their purchasing lifestyle.

The  formula for Income elasticity of demands given by

The percent change in quantity demanded divided by the percent change in income.

2) Income elasticity of demand, helps us to identify  if a particular good represents a necessity or a luxury.

-when the income elasticity for a good is less than 1(ie from 0-1) we say that the good is a normal good. these goods are also called necessity goods and consumers will purchase them irrespective of the changes in their  income eg water, electricity

- when the income elasticity of a good is greater than 1 , we say that  the good is a luxury good. eg butter

- An inferior good is one with a negative income elasticity  which means  rising incomes will lead to a drop in demand.

Answer:

1) The correct answer is letter "A": how responsive quantity demanded is to changes in income.

2) The correct answer is letter "A": a luxury good.

Explanation:

1) Income elasticity of demand refers to the fluctuations of the quantity demanded in front of changes in income. It is calculated by dividing the percentage change of quantity demanded by the percentage change in income. If the result is greater than (1) or equal to (0), the demand is elastic. If the result is lower than (1) the demand is inelastic.

2) In case the demand elasticity of butter is 0.11, it implies it is elastic. It means in front of small changes in income, would change exponentially the quantity demanded for butter. This characteristic is typical in luxury items since when people's income increase the quantity demanded increase and when people's income decrease so does quantity demanded.
