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: -Supply curve shift: Changes in production cost and related factors can cause an entire supply curve to shift right or left. This causes a higher or lower quantity to be supplied at a given price. The ceteris paribus assumption: Supply curves relate prices and quantities supplied assuming no other factors change.

Detailed explanation-3: -Factors that can shift the demand curve for goods and services, causing a different quantity to be demanded at any given price, include changes in tastes, population, income, prices of substitute or complement goods, and expectations about future conditions and prices.

Detailed explanation-4: -An increased number of workers will cause the supply curve to shift to the right. An increased number of workers can be due to several factors, such as immigration, increasing population, an aging population, and changing demographics.
