ECONOMICS (CBSE/UGC NET)

Detailed explanation-1: -The curve shifts to the right if the determinant causes demand to increase. This means more of the good or service are demanded even though there’s no change in price. When the economy is booming, buyers’ incomes will rise. They’ll buy more of everything, even though the price hasn’t changed.

Detailed explanation-2: -The demand curve shifts when the quantity of a product or service demanded at each price level changes. If the quantity demanded at each price level increases, the demand curve shifts rightward. Inversely, if the quantity demanded at each price level decreases, the demand curve will shift leftward.

Detailed explanation-3: -A decrease in the price of a complementary product will result in a rightward change in the demand curve.

Detailed explanation-4: -A helpful hint to remember that more demand shifts the demand curve to the right. A leftward shift in demand would decrease the quantity demanded to 20 units at the price of $40. With a decrease in demand, there is a lower quantity demanded at each an every price along the demand curve.
