Marketing is not confined to any particular type of economy, because goods must be exchanged and therefore marketed in all economies and societies except perhaps in the most primitive. Furthermore, marketing is not a function that is limited to profit-oriented business; even such institutions as hospitals, schools, and museums engage in some forms of marketing. Within the broad scope of marketing, merchandising is concerned more specifically with promoting the sale of goods and services to consumers (i.e., retailing) and hence is more characteristic of free-market economies.

This is so, if revenue for the product comes from efficiency savings in production, over actual sales of a good/service. However, if a product services a niche market, or is complementary to another product, it may continue the manufacture of the product, despite a low level of sales/revenue being accrued.
