Question. Market for a good is in an equilibrium. There is simultaneous decrease both in demand and supply, but there is no change in the market price. Explain with the help of diagram, how it is possible.
Answer : When there is decrease in demand is more than decrease in supply, then there is no change in the market price. When decrease in demand is proportionately more than decrease in supply, then leftward shift in demand curve from DD to D1D1 is proportionately more than leftward shift in supply curve from SS to S1S1. The new equilibrium is determined at E1, equilibrium price falls from OP to OP1 and equilibrium quantity falls from OQ to OQ1.
Question. How a fall in the price of tea will affects an equilibrium price of coffee? Explain the chain effects.
Answer : With a fall in price of tea, the demand of coffee that is substitute of tea decreases. As a result, demand curve of coffee shifts to the left. Accordingly, an equilibrium price would tend to decrease and also an equilibrium quantity tends to decrease.
The figure shows a situation of decrease in demand. The demand curve shifts to left side. Consequently, equilibrium price and quantity, both are decreasing from OP to OP1 and OQ to OQ1.
