Investment is a component of aggregate demand that represents all spending by firms on capital equipment, inventories, and technology, and it excludes financial investment. In the aggregate demand identity, this I term captures real purchases that boost future productive capacity, including business fixed investment and changes in inventories. Financial investments like bonds or mutual funds involve switching ownership of existing assets rather than spending on goods and services, so they aren’t counted as investment in aggregate demand. Proportional tax is a tax policy effect on income, not a direct component of spending, and bonds or mutual funds are financial assets, not firm purchases of capital goods. So this choice best matches spending by firms on productive assets, excluding financial investment.
