The Law of Demand states that, other factors remaining constant, as the price of a good or service increases, its quantity demanded decreases, and vice versa. For example, if the price of apples is ₹200 per kg, a consumer might buy only 1 kg. However, if the price falls to ₹100 per kg, the same consumer might be willing to buy 2 kg, showing an inverse relationship between price and quantity demanded.
2
Substitute goods are those that can replace each other to satisfy a want. If the price of coffee increases while the price of tea remains the same, consumers may switch from coffee to tea. This would lead to an increase in the demand for tea, even if its own price has not changed.
3
Market demand is the total quantity of a product that all potential buyers in a market are willing and able to buy at different prices. Individual demand refers to the quantity that a single consumer is willing and able to buy at different prices. Market demand is the sum of all individual demands.
4
Besides price, the supply of a product is influenced by:a. Price of related goods: If the price of an alternative product becomes more profitable, suppliers might shift production.b. Number of sellers: More sellers generally lead to higher market supply.c. Technology: Improved technology can lower production costs and increase supply.d. Future expectations: If sellers expect prices to rise, they might reduce current supply.e. Input costs: Higher costs of raw materials or labour can reduce supply.
5
The Law of Supply states that, other factors remaining constant, as the price of a good or service increases, the quantity supplied increases, and vice versa. This is because higher prices generally lead to higher profitability, encouraging producers to supply more. For instance, if the price of wheat rises, farmers will be incentivized to produce and sell more wheat.

Market equilibrium is the point where the quantity demanded of a good or service equals the quantity supplied at a specific price. At this price, there is no excess demand (shortage) or excess supply (surplus), and the market is considered 'cleared'.Diagram: A graph with Price on the y-axis and Quantity on the x-axis. Draw a downward-sloping demand curve (DD') and an upward-sloping supply curve (SS'). The point where these two curves intersect is the equilibrium point (E). Draw dashed lines from E to the y-axis to show the Equilibrium Price (Pe) and to the x-axis to show the Equilibrium Quantity (Qe).

a. This change indicates an increase in the quantity demanded for mangoes as the price fell.b. This scenario illustrates the Law of Demand.c. Possible reasons for the fall in the price of mangoes include: a bumper harvest (increased supply), arrival of the peak mango season, seasonal factors, or a decrease in consumer income making mangoes less affordable at higher prices.

If essential medicines become unaffordable, the government can intervene by:a. Implementing a price ceiling: Setting a maximum price that sellers can charge for these medicines to ensure affordability for all.b. Subsidizing the production or purchase: Providing financial assistance to manufacturers to lower production costs or directly subsidizing consumers to reduce their out-of-pocket expenses.c. Regulating unfair practices: Investigating and penalizing any instances of hoarding or black marketing of essential medicines.d. Ensuring adequate supply: Working with manufacturers to ensure sufficient quantities are produced and distributed.

Complementary goods are those that are used together to satisfy a want. For example, cars and petrol. If the price of cars increases significantly, the demand for cars may fall. Consequently, the demand for petrol, which is used with cars, is also likely to decrease, even if the price of petrol remains unchanged.
10
Improved technology typically reduces the cost of production and increases efficiency. For example, the adoption of drip irrigation in farming can lead to better crop yields with less water. This cost reduction and increased output would make farmers more willing to supply larger quantities of their produce at various prices, thus increasing the overall market supply.
11
A price ceiling is a government-imposed maximum price that can be charged for a product or service. For example, the government may set a maximum price for masks during a pandemic. A price floor is a government-imposed minimum price. For example, the government often sets a minimum support price for agricultural products to ensure farmers receive a reasonable income.
12
The market demand curve is flatter than an individual demand curve because it aggregates the demand of many consumers. A small change in price can lead to a much larger change in the total quantity demanded across all consumers in the market compared to the change in quantity demanded by a single individual.
13
A buyer's tastes and preferences play a crucial role in determining demand. If a consumer has a strong preference for a particular brand of coffee, they will likely demand more of it, even if it is slightly more expensive than other brands. Conversely, if tastes shift away from a product, demand will fall regardless of its price.
14
If there is a sudden increase in the number of sellers for a particular good, the market supply will increase. This excess supply, if demand remains constant, will put downward pressure on prices. The market will move towards a new equilibrium where the price is lower, and the quantity traded is higher.
15
Diminishing marginal utility is the principle that as a consumer consumes more units of a product, the additional satisfaction (utility) derived from each successive unit decreases. For example, the first slice of pizza provides high satisfaction, but the fifth slice provides much less. This decrease in perceived usefulness leads consumers to be willing to buy less at higher prices or at lower prices if they have already consumed a lot.
16
a. The increase in decorative lights needed for festivals represents an increase in demand. The manufacturers increasing production to meet this demand represents an increase in supply.b. With increased demand and increased supply, the effect on price is ambiguous and depends on the magnitude of the shifts. However, if demand outstrips the initial supply increase, prices might rise temporarily. If the supply increase is substantial and quick, prices might stabilize or even fall from an initial spike.c. The equilibrium quantity traded would likely increase. The equilibrium price might increase, decrease, or remain the same depending on whether the demand shift or the supply shift is larger.
17
Public goods, such as national defence, roads, or street lighting, are non-excludable (everyone can benefit, even if they don't pay) and non-rivalrous (one person's use doesn't diminish another's). Private companies are unlikely to provide these goods because they cannot easily charge users for them and make a profit, leading to a free-rider problem. Governments provide them to ensure social welfare and public benefit.
18
Hoarding is the accumulation of goods beyond immediate needs, often in anticipation of shortages or price increases. Black marketing is the illegal trade of goods at prices above the legally permitted maximum or for banned items. The government might intervene by declaring such goods as essential commodities, capping prices, increasing supply through imports or increased domestic production, and enforcing penalties for hoarding and black marketing.
19
If consumers expect prices to rise in the future, they will tend to buy more of the product now to avoid paying higher prices later. This increases current demand. Conversely, if they expect prices to fall, they will postpone their purchases, leading to a decrease in current demand. For example, people might buy gold before a festival if they expect its price to increase afterwards.
20
Excessive government regulation can have several adverse effects:a. Price distortions: Fixing prices below market levels (price ceiling) can lead to shortages as producers are less motivated to supply. Fixing prices above market levels (price floor) can lead to surpluses.b. Compliance burdens: Businesses, especially small ones, may face significant costs and time in complying with numerous regulations, licenses, and permits, hindering ease of doing business.c. Discourages innovation: Heavy regulation and price controls can reduce incentives for businesses to invest in new technologies or innovative practices, leading to lower long-term productivity and output.
