Three types of economic roles are consumers, producers, and workers.

The role of the producer is to produce the good and services. The sum of the quantities produced of a good or service by the different producer of a same product constitute the supply of the product. Thus, the producer posseses the assets to make the products available, which is what a factory owner represents.
