What is NOT included in consumer expenditures?

Consumer expenditures refer specifically to the spending habits of individuals and households on goods and services. This category primarily encompasses purchases made by consumers, such as household spending on groceries, services, and entertainment. In contrast, business investment pertains to the spending by businesses on capital goods, such as machinery, equipment, and buildings, which is not directly related to the consumption activities of individual consumers. Therefore, business investment is distinctly separate from consumer expenditures, making it the correct choice in this context.
