Question

His income increased dramatically;from$5000 a year to $60,000 a year. Jim decides that instead of using the bus, he would buy a car. This implies that_______.

Answer 1

Answer:

This implies that bus is an inferior good and car is a normal good.

Explanation:

Initially, Jim's income was $5000 a year.

As his income increases to $60,000 a year, he decides to buy a car instead of using the bus.  

In other words, with the increase in income, the demand for traveling by bus is declining.  

This implies that it is an inferior good.  

The demand for the car is increasing with an increase in income.  

So, the car is a normal good.  

An inferior good can be defined as a product that shows negative elasticity. This means with an increase in income its demand declines an vice versa.

A normal good can be defined as a product that shows positive income elasticity. That is, its demand increases with rise in income and vice versa.
