ECONOMICS (CBSE/UGC NET)

Detailed explanation-1: -When there is an increase in unit tax on the production of goods by the government, the unit cost of production will rise and consequently, the firm would supply less than before at the given price. The supply would decrease implying that the supply curve would shift to the left.

Detailed explanation-2: -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-3: -An increase in the change in supply shifts the supply curve to the right, while a decrease in the change in supply shifts the supply curve left.

Detailed explanation-4: -Shifts of the supply curve occur when quantities of a product or service supplied change at every given price in response to other economic factors. If the quantity of the product/service supplied at each price level increases due to economic factors other than price, the respective supply curve would shift rightward.

Detailed explanation-5: -A shift in the supply curve is brought about by a change in supply. Changes in production cost and related factors can cause an entire supply curve to shift right or left.
