The term inferior goods refers to goods that consumers demand less of when their incomes increase. The demand of this good would also decrease when the real GDP of the country increases. This would happen when a good would have a substitute that has more cost or price which would have an increase its demand as the people improve their income. An example would be coffee. A coffee from Mcdonald would be inferior to the coffee that is from Starbucks. When a person's income decrease, he would tend to buy coffee daily from McDonald since it is more affordable as compared to Starbucks. However, when his income rises, he would be preferring the one from Starbucks.
