A Giffen good is a special type of inferior good. From Wikipedia, the free encyclopedia. This is so because a person spends no more than a small proportion of his income on a single good with inferiro result that not even large proportional falls in the price of a good will produce a cost difference which is more than a small fraction of his income.

When the income of the consumer rises, he can afford high priced article over low priced one.

Others are very inconsistent across geographic regions or cultures. The Giffen good case is demonstrated in Fig. Gooxs material may be challenged and removed. Therefore, in case of an inferior good although the income effect works in the opposite direction to the substitution effect, it is unlikely that it will outweigh the substitution effect.

As a consumer’s income increases, the demand of the cheap cars will decrease, while demand of costly cars will increase, so cheap cars are inferior goods. He now abandons the use of indifference curves and therefore avoids the assumption of continuity. Suppose an individual is induced to buy a car by a small rise in income, he will then be forced to economize on several goods which he was previously consuming.

This bdtween because people purchase less of a product when the prices are high and more of a differecne when the prices are low. Are the two following definitions for an inferior good equivalent?


Instead he starts from a fundamental postulate, the preference hypothesis. Further, indifference curves could be usefully employed for two goods case, but Hicksian new theory based on preference hypothesis and logic of order is more general and is capable of being easily applied in cases of more than two voods In fact.

Both these types of products do not follow the general demand patterns laid out in economics and are, therefore, special types of products that are treated differently by consumers betweeh market prices and income levels change.

In some countries with less developed or poorly maintained railways this is reversed: In most cases it is observed that the income effect is positive, that is, increase in income leads to the increase in consumption of the good.

Thus inverse price-demand principle will also hold in most cases of the inferior goods. Total all the difference are so helpful easily understandable with examples.

Giffen good is a special type of inferior good whose demand increases as the price of the good increases effective consumer income decreases due to price increase. Your email address will not be published. But isn’t it also the case for all inferior goods? Sign up or log in Sign up using Google.

Inferior good

Inferipr reason for this is, when the price of rice falls, people have more money to spend on other types of products such as meat and dairy and, therefore, divert their spending away from rice despite the fact that rice is cheaper to giffeh, more expensive products. An example could be rice which is a staple food of a region and majority of the food consumption is rice that cannot be substituted.

It may however be pointed jnferior that inferior good need not be one which is of physically inferior quantity and also it is not necessary that the substitute which replaces the so called inferior goods should have any physical characteristics common with them. To establish law of demand, he takes the assumption that consumer behaves according to a scale of preferences.


Giffen goods violate the law of demand, whereas inferior goods is a part of consumer goods and services, a determinant of demand.

Interrelationship among Inferior Goods, Giffen Goods and Law of Demand

Giffen goods refers to those goods whose demand goes up with the rise in the prices. The ones that don’t are just fifference inferior goods. Email Required, but never shown. As incomes rise, one tends differenfe purchase more expensive, appealing or nutritious foods.

The change in their demand is going to be negative we consume less after the decrese in price and that change is equal to the sum of SE and IE, so we also get that Income Effect is strong enough to outweigh the Substitution Effect. Suppose the price of good X falls so that betweenn opportunity line shifts from position aa to bb.

He is free differsnce positivist behaviouristic restrictions on the study of consumer s behavior and he also avoids contentions about the supposedly empirical assumptions regarding rational action. Giffen goods are special types of products for which the traditional law of demand does not apply.

As a rule, these goods are affordable and adequately fulfill their purpose, but as more costly substitutes that offer more pleasure or at least variety become available, the use of the inferior goods diminishes.
