OR x is a normal good for its consumers. Their income increases. Explain its chain of effects on equlltbrium price, demand and supply of X. (use diagram) | 
| Answer» An increase in income of the consumer leads to increase in demand for the commodity or a rightwards shift in the demand curve. The increase in demand leads to competition among buyers causing a push in the market price. The increased price leads to an increase in the supply and a fall in demand leading to a new equilibrium where both the price and quantity demanded are higher. | |
