EXCEPTIONS OF LAW OF DEMAND
Demand is that specific quantity of a commodity which the consumer purchases at a specific price during a specified time period.
ACCORDING TO FERGUSON
“Demand refers to the quantities of commodity that the consumers are able and willing to purchase at each possible price during a period of time, other things being equal.”
EXCEPTIONS OF LAW OF DEMAND
Exceptions of law of demand state the areas where law of demand does not apply. The law of demand fails when any of its assumption does not gets fulfilled. The main exceptions of law of demand are as follows:
VEBLEN GOODS OR ARTICLES OF DISTINCTION
Such commodities which are considered as symbol of status and known as Articles of Distinction. This exception was first explained by the American Economist Veblen. That is why; these articles or goods are known as Veblen goods. Such commodities are generally consumed by the rich. The higher the price of these goods, the more will be their demand and vice versa. This makes the demand curve slopes upward.
INFERIOR GOODS
The law of demand applies only to the normal goods. This law does not apply to the inferior goods. Inferior goods are those goods which are relatively cheap in nature. If the prices of these goods rise, their demand also rises. And if the price of these goods decreases, their demand falls.
IGNORANCE OF CONSUMER
Many times, the consumer thinks that the cheap commodity is inferior commodity. Hence the consumers purchase less if its price is low. On the contrary, if the price rises, the consumer takes it as superior in quality and purchases more of it. This makes the demand curve slopes upward and law of demand fails.
ABNORMAL CIRCUMSTANCES
The law of demand does not apply in abnormal circumstances like war, floods, earthquake etc. In such circumstances, the demand for necessary commodities rises even though their price is higher. On the other hand, the demand for other than necessary commodities falls even though their price is low.
GIFFEN GOODS
The concept of these goods was given by Sir Robert Giffen. At his name, these goods are known as Giffen Goods. Giffen goods are highly inferior goods, showing a very high negative income effect. As a result, when price of such commodities falls, their demand also falls, even when they happen to be relatively cheaper than other goods. This is popularly known as ‘Giffen Paradox’.
In short, it can be said that the law of demand applies only when all its assumption holds good. Otherwise it fails.
