A model’s marketability in the fashion world depends upon the image that is desired by his employer or dictated by the product or service he is promoting. While an image of athletic virility may be required to advertise youth-oriented goods, a more mature image may be preferred to promote services and products normally purchased by older consumers. A model who can convincingly portray a wide range of ages, styles and personalities can significantly improve his marketability.

The model of pure competition implies that risk-adjusted rates of return should be constant across firms and industries. However, numerous economic studies have affirmed that different industries can sustain different levels of profitability; part of this difference is explained by industry structure.Michael Porter provided a framework that models an industry as being influenced by five forces. The strategic business manager seeking to develop an edge over rival firms can use this model to better understand the industry context in which the firm operates.If rivalry among firms in an industry is low, the industry is considered to be disciplined. This discipline may result from the industry's history of competition, the role of a leading firm, or informal compliance with a generally understood code of conduct. Explicit collusion generally is illegal and not an option; in low-rivalry industries competitive moves must be constrained informally.
