Consumer demand theory relates preferences for the consumption of both goods and services to the consumption expenditures; ultimately, this relationship between preferences and consumption expenditures is used to relate preferences to consumer demand curves. As the price of a commodity falls, consumers move toward it from relatively more expensive goods (the substitution effect). Measurement of Productivity and Efficiency: Theory and Practice.
