The continuous movement of production, income, and resources between producers and consumers. This flow moves through product markets as the gross domestic product of our economy and is then the revenue received by the business sector in payment for this production. This stream of revenue then flows through resource markets as payments by businesses for the resources employed in production. The payments received by resource owners, however, is nothing more than the income of the household sector. The resource owners of the household sector use this income to purchase goods and services through the product markets, coming full circle to where we began.
