ECONOMICS (CBSE/UGC NET)

Detailed explanation-1: -A change in the number of sellers in an industry changes the quantity available at each price and thus changes supply. An increase in the number of sellers supplying a good or service shifts the supply curve to the right; a reduction in the number of sellers shifts the supply curve to the left.

Detailed explanation-2: -When the government gives a subsidy on the production of a good, marginal and average costs of production tend to fall. Accordingly, producers will supply more at the same price or supply the same quantity at the lower price.

Detailed explanation-3: -Changes in factors like average income and preferences can cause an entire demand curve to shift right or left. This causes a higher or lower quantity to be demanded at a given price. Ceteris paribus assumption. Demand curves relate the prices and quantities demanded assuming no other factors change.

Detailed explanation-4: -What Factors Can Affect the Supply Curve? The supply curve can shift based on several factors including changes in production costs (e.g., raw materials and labor costs), technological progress, the level of competition and number of sellers/producers, and the regulatory & tax environment.
