Similarly, there will be almost no discussion of welfare economics such normative issues certainly influenced the history of consumer choice theory, but the focus here will be choice theory as an attempt to describe, predict, or explain the behaviour of individual consumers. The theory of consumer choice is useful in this situation since it provides an explanation of how people make decisions and how their savings depend on the interest rate for instance, in a case when the person is young and working, he/she will consume part of the income and save the rest. The theory of utility maximization allows us to ask how a utility-maximizing consumer would respond to a particular event by following the marginal decision rule, consumers will achieve the utility-maximizing condition: expenditures equal consumers’ budgets, and ratios of marginal utility to price are equal for all pairs of goods and services.
