What is the law of demand?
The law of demand states that when the price of a product increases, its demand generally decreases. Similarly, when the price decreases, consumers tend to buy more of that product, assuming all other factors remain constant. This creates an inverse relationship between price and demand.
- Higher price leads to lower demand.
- Lower price leads to higher demand.
- Price and demand have an inverse relationship.
- Other factors like income and preferences remain constant.
- Represented by a downward-sloping demand curve.
What factors affect demand?
Demand is not influenced only by the price of a product. Many other economic and social factors also affect consumer demand. A change in these factors shifts the entire demand curve instead of causing movement along the curve.
- Price of the commodity
- Consumer income
- Population size
- Consumer tastes and preferences
- Prices of substitute goods
- Prices of complementary goods
- Weather and seasonal conditions
- Future expectations
- Cultural and social factors

How is movement different from a shift in the demand curve?
Students often confuse movement and shift in the demand curve. Understanding this difference is very important because direct questions are asked in the JAIIB examination.
| Movement in Demand Curve | Shift in Demand Curve |
| Caused by change in price | Caused by factors other than price |
| Same demand curve | New demand curve |
| Quantity demanded changes | Entire demand changes |
| Law of demand applies | Determinants like income or preferences change |
What is the law of diminishing marginal utility?
The law of diminishing marginal utility explains that the satisfaction received from consuming additional units of the same product keeps decreasing. The first unit provides the highest satisfaction, while every additional unit gives comparatively less satisfaction.
- First glass of water gives maximum satisfaction.
- Second glass gives less satisfaction.
- Third or fourth glass provides even lower satisfaction.
- Continuous consumption may even reduce satisfaction.
What is the law of supply?
The law of supply states that producers are willing to supply more goods when market prices increase because they can earn higher profits. When prices fall, producers reduce supply.
- Price and supply have a direct relationship.
- Higher price increases supply.
- Lower price decreases supply.
- Represented by an upward-sloping supply curve.
- Producers focus on profit maximization.

What factors affect supply?
Apart from market price, several other factors influence the quantity supplied by producers. These factors can shift the supply curve to the left or right.
- Cost of production
- Price of raw materials
- Technology
- Government taxes and subsidies
- Weather conditions
- Market expectations
- Availability of resources
- Prices of related goods
What is market equilibrium?
Market equilibrium is the point where the quantity demanded by consumers becomes equal to the quantity supplied by producers. At this point, the market reaches balance, and there is no pressure for the price to change unless other factors change.
- Demand equals supply.
- Stable market price.
- Stable quantity.
- No shortage or surplus.
- Price remains unchanged unless determinants shift.
What are the exceptions to the law of demand?
Although the law of demand generally applies to most products, there are certain situations where demand may increase even when prices rise.
| Exception | Explanation |
| Veblen Goods | Expensive luxury goods purchased for status and prestige |
| Giffen Goods | Inferior goods where demand increases despite a price rise |
| Necessary Goods | Essential goods like medicines and salt where demand changes very little |
| Increase in Income | Higher income can maintain or increase demand even when prices rise |
Why is equilibrium price important in economics?
Equilibrium price ensures that producers and consumers are both satisfied. It prevents excess supply and shortages in the market while maintaining price stability.
- Maintains market balance.
- Eliminates surplus.
- Reduces shortages.
- Helps efficient resource allocation.
- Indicates a stable market condition.

Demand is the quantity of a good or service that consumers are willing and able to buy at different prices.
The law of demand states that as the price of a product increases, its demand decreases, keeping other factors constant.
Market equilibrium is the point where the quantity demanded equals the quantity supplied, determining the equilibrium price.
