Final answer:
Claire's behavior is an example of conspicuous consumption, a trend where purchases are used to make a social statement, reflecting a society where consumption symbolizes success and pleasure.
Step-by-step explanation:
Claire's preferences for young-looking fashions and driving a new red convertible sports car is an example of the consumer buyer behavior trend known as conspicuous consumption. This behavior involves purchasing and using products to make a statement about one's social standing. In Claire's case, her choice of clothing and vehicles may be a way to assert a youthful identity or status, despite her age.
The concept of conspicuous consumption dates back to Thorstein Veblen's theory in the 19th century, which described the buying and displaying of goods to flaunt one's wealth and social status. Over time, with the rise of middle class affluence and the availability of credit, the ability to purchase goods not just for necessity but for enjoyment and status became more widespread. Claire's behavior can also be seen as an expression of autonomy, as historically, consumption has become a pursuit of pleasure and a symbol of success in society.
