Microeconomics: Income and Demand
A consumer is able to purchase a normal good and has a demand curve, D1, which provides the relationship between price and quantity given his preferences, income and other consumption attributes. Assuming an increase in his income, ceteris paribus, his demand curve would shift outward to D2, corresponding to a higher quantity for each purchase price. The consumer would then move his consumption for the good from Q1 to Q2, increasing his purchase of the good.
