Q.Explain any five determinants of demand for a commodity, other than its own price.

Besides its own price, demand for a good depends on income, related-goods' prices, tastes, expectations and the number of buyers, among other factors.

1. Income of the consumer: A rise in income generally raises demand for normal goods and may lower demand for inferior goods past a point.

2. Price of related goods: For substitutes (tea and coffee), a rise in one good's price raises demand for the other. For complements (car and petrol), a rise in one good's price lowers demand for the other.

3. Tastes, preferences and fashion: A favourable shift in taste (e.g. a health trend favouring a particular food) raises its demand even without any price change.

4. Consumer's price expectations: If buyers expect the price of a good to rise in the near future, they tend to buy more of it NOW, raising current demand; an expected price fall has the opposite effect.

5. Number of buyers in the market: A larger population or a larger number of buyers in a market segment raises total market demand at every price, independent of any price change.

(Other acceptable determinants: distribution of income and wealth, government tax/subsidy policy, advertising and sales promotion, and seasonal/climatic factors.)

Listing the good's OWN price as one of the "other" determinants — the question specifically excludes it, since own-price is studied separately under the Law of Demand.
