Question
Write Explanatory answer.
State and explain the law of demand with its exception.
Solution
Meaning: -The Law of demand establishes the functional relationship between the Price of a commodity and the quantity of that commodity demanded at different prices, assuming other factors remaining constant.
When the price of a commodity rises, demand for it falls and when the price of the commodity falls, demand rises. So less quantity is demanded at higher prices and more quantity is demanded at lower prices. There exist inverse relationship between price and quantity demanded of a commodity.
Definition: -According to Marshall the law of demand, is defined as “Other things being equal, the quantity of a commodity demanded varies inversely with its price.”
Symbolically, the Law of demand can be expressed as follows:
Dx = f (Px)
Where, D = stands for the demand for commodity X
X stands for the commodity demanded
F stands for function of
Px stands for the price of the commodity X
We can explain this law with the help of a schedule and a diagram.
| Price (Rs.) | Quantity Demanded |
| 1 | 50 |
| 2 | 40 |
| 3 | 30 |
| 4 | 20 |
| 5 | 10 |
The Schedule shows that with an increase in Price the quantity demanded is decreasing. It indicates inverse relationship between the two variables price and quantity demanded. When the price is Re. 1 the consumer demand 50 units and when the price rises to Rs. 5 he demands the least that is 10 units.
In the above diagram X-axis represents quantity demanded and Y-axis represents price. Various points from the schedule are plotted on the graph, joint those points we will be getting demand curve. DD is the demand curve which slopes downward from left to right indicating inverse relationship between price and Quantity demanded. This happens when the price is more, demand is less and when price is less, and demand is more.
- Giffen goods or inferior goods-Giffen Paradox: -Inferior goods are those goods whose demand does not rise even if their price falls. At times, the demand decrease, when the price of such gods falls. Sir Robert Giffen discovered this behaviour in England in relation to inferior goods such as bread. Therefore inferior goods are named after Giffen and they called ‘Giffen Goods’.
- Prestige Goods: There are certain goods and services, which represent ‘Status’ of ‘Prestige’for the people. Demand for these commodities is more when the price is more.
- Anticipation of changes in price: -If people anticipate a further rise in price, they may buy more at the existing higher price. Likewise, if people anticipating a further fall in price, they will not buy more even at the existing lower prices. They will wait for the price to fall further.
4. Price Illusion: -There is a belief among the people that the higher is the price, the better is the product and accordingly the greater is the demand for such goods.
- Changes in fashion: The law of demand may not work, if there is change in fashion. For example, if a product goes out of fashion and its price falls down, people will not buy more of it even at very low prices.
- Promotional activates: - Promotional activities such as advertising and salesmanship undertaken by seller can make the people buy more even at high prices.
- Changes in quality: if there is a change in the quality of the product, the law of demand may not apply. For instance, if there is improvement in quality of the product, some people my demand more even at higher price.

Read the following news report and answer the Q.97-Q.100 on the basis of the same:
The quantity of a commodity that a consumer is willing to buy and is able to afford, given the prices of goods and the consumer's tastes and preferences is called demand for the commodity. Whenever one or more of these variables change, the quantity of the good Chosen by the consumer is likely to change as well. The relation between the consumer's optimal choice of the quantity of a good and its price is very important and this relation is called the demand function. Thus, the consumer's demand function for a good gives the amount of the good that the consumer chooses at different levels of its price when the other things remain.
In which of the following cases there will be leftward shift in demand?

The Coca-Cola products can be termed as normal goods and in August 2019 Coca-Cola introduced a new product into the market, that is, zero sugar where the demand has increased for the product in the market.
According to the council of the Australian Food Technology Association and Institute of Food Science and Technology, the Australian nonalcoholic beverages industry has been growing steadily, with a 2.3 percent increase in overall production in the year 2000 which amounts to 2.25 billion liters. However, in the re~ent years, sales of customary carbonated soft drinks have dropped as more and more customers become health conscious and move away from high-calorie sugary drinks. Soft Carbonated drinks. and other alcohol-free beverage manufacturers have also sensed the effects of intensifying competition from private-label soft drink makers. Nevertheless, sales of greater value energy and sports drinks have driven profit generation in the industry.
