Final answer:
A shirt company with higher pricing due to brand name operates in a monopolistically competitive market, characterized by product differentiation and brand value.
Step-by-step explanation:
A shirt company that produces the same type of shirt as others but with a higher price due to its brand name would be an example of a monopolistically competitive market. This market structure is characterized by a large number of sellers offering differentiated products that are not perfect substitutes for one another. In such a market, a well-respected brand name like Coolshirts can sell its shirts at higher prices due to the perceived quality or personality of the brand. The differentiation is critical and is built through marketing, innovation, or discernible features which, although not entirely unique, are distinct enough from competitors to allow some degree of pricing power. Here, the differentiation arises from the brand same rather than the physical characteristics of the product.
Differentiated products, including those in the clothing industry, can lead to product differentiation and monopolistic competition, where variety in styles and brand perception plays a pivotal role in consumer choice. The example of Coolshirts selling 10 t-shirts at $9 each exemplifies a business operating within a monopolistically competitive market where its pricing reflects the brand value and its position in the crowded market landscape.
