In economics, investment spending is primarily associated with which form of spending?

• A. Government purchases
• B. Business capital formation
• C. Household consumption
• D. Net exports

Answer: (B)

Investment spending in macroeconomics is spending on capital goods—tools, buildings, software, and changes in inventories—that will be used to produce more goods and services in the future. This is what economists mean by business capital formation. It includes purchases by firms of equipment, factories, and software, as well as increases in inventories that expand the economy’s future productive capacity. In GDP accounting, this is the I component of Y = C + I + G + NX, representing spending that adds to the capital stock. Therefore, the best description is spending by businesses on capital formation. This differs from government purchases (spending by the government on goods and services), household consumption (spending on current goods and services for immediate use), and net exports (exports minus imports).
