Income Elasticity of Demand

Calculate the income elasticity coefficient when the quantity demanded of a good increases by 10% in response to a 5% increase in income.

If the income elasticity coefficient for a luxury good is 2.5, what does this indicate about the demand for the good when income increases?

• The demand for the luxury good increases significantly when income increases.

• The demand for the luxury good decreases when income increases.

• The demand for the luxury good remains the same when income increases.

• The demand for the luxury good increases slightly when income increases.

Explain the meaning of a negative income elasticity coefficient in the context of demand for a particular good.

• As income increases, the demand for the particular good increases.

• A negative income elasticity coefficient means there is no relationship between income and demand for the particular good.

• As income increases, the demand for the particular good decreases.

• The negative income elasticity coefficient indicates that the demand for the particular good is constant regardless of changes in income.

If the income elasticity coefficient for a necessity good is 0.6, what does this indicate about the demand for the good when income increases?

• The demand for the good increases, but at a slower rate than the increase in income.

• The demand for the good increases at the same rate as the increase in income

• The demand for the good decreases as income increases

• The demand for the good remains constant as income increases

Calculate the income elasticity coefficient when the quantity demanded of a good decreases by 8% in response to a 12% increase in income.

• 1.25

• 0.5

• 0.75

• -0.67

What does an income elasticity coefficient of 1.2 indicate about the demand for a normal good when income increases?

• The demand for the normal good decreases by 1.2% for every 1% increase in income.

• The demand for the normal good remains constant regardless of the increase in income.

• The demand for the normal good increases by 1.2% for every 1% increase in income.

• The demand for the normal good increases by 2.5% for every 1% increase in income.

Explain the concept of income elasticity of demand and its significance in analyzing consumer behavior.

• Income elasticity of demand is not relevant in analyzing consumer behavior

• Income elasticity of demand only applies to luxury goods

• Income elasticity of demand measures the price sensitivity of consumers

• Income elasticity of demand is a measure of how much the quantity demanded of a good responds to a change in consumer income. It is significant in analyzing consumer behavior as it helps in understanding the impact of income changes on the demand for different goods and services.

If the income elasticity coefficient for an inferior good is -0.4, what does this indicate about the demand for the good when income increases?

• Demand for the good remains constant as income increases

• Demand for the good is not affected by changes in income

• Demand for the good increases as income increases

• Demand for the good decreases as income increases

Calculate the income elasticity coefficient when the quantity demanded of a good increases by 15% in response to a 20% increase in income.

• 2.0

• 0.25

• 0.75

• 1.5

Discuss the relationship between income elasticity of demand and the type of goods (luxury, necessity, inferior) in the context of consumer behavior.

• Inferior goods have low income elasticity

• Luxury goods have negative income elasticity

• The income elasticity of demand is related to the type of goods as luxury goods have high income elasticity, necessities have low income elasticity, and inferior goods have negative income elasticity.

• Necessities have high income elasticity
