The income approach equates the total output of a nation to the total factor income received by residents or citizens of the nation. The main types of factor income are: Employee compensation (cost of fringe benefits, including unemployment, health, and retirement benefits); Interest received net of interest paid; Rental income (mainly for the use of real estate) net of expenses of landlords; and Royalties paid for the use of intellectual property and extractable natural resources. All remaining value added generated by firms is called the residual or profit. If a firm has stockholders, they own the residual, some of which they receive as dividends. Profit includes the income of the entrepreneur - the businessman who combines factor inputs to produce a good or service.
