<P> Inter-city bus service is also an example of an inferior good . This form of transportation is cheaper than air or rail travel, but is more time - consuming . When money is constricted, traveling by bus becomes more acceptable, but when money is more abundant than time, more rapid transport is preferred . In some countries with less developed or poorly maintained railways, for example Serbia, this is reversed: trains are slower and cheaper than buses, so rail travel is an inferior good . </P> <P> Certain financial services, including payday lending, are inferior goods . Such financial services are generally marketed to persons with low incomes . People with middle or higher incomes can typically use credit cards that have better terms of payment or bank loans for higher volumes and much lower rates of interest . </P> <P> Inexpensive foods like instant noodles, bologna, hamburger, mass - market beer, frozen dinners, and canned goods are additional examples of inferior goods . As incomes rise, one tends to purchase more expensive, appealing and nutritious foods . Likewise, goods and services used by poor people for which richer people have alternatives exemplify inferior goods . As a rule, used and obsolete goods (but not antiques) marketed to persons of low income as closeouts are inferior goods at the time even if they had earlier been normal goods or even luxury goods . </P> <P> Others are very inconsistent across geographic regions or cultures . The potato, for example, generally conforms to the demand function of an inferior good in the Andean region where the crop originated . People of higher incomes and / or those who have migrated to coastal areas are more likely to prefer other staples such as rice or wheat products as they can afford them . However, in several countries of Asia, such as Bangladesh, potatoes are not an inferior good, but rather a relatively expensive source of calories and a high - prestige food, especially when eaten in the form of "French fries" by urban elites . </P>

Most goods can be classified as normal goods rather than inferior goods
