Identify and describe a specific good or service that has been differentiated by a firm that sells that good or service as a Monopolistic Competitor. The market I chose was the clothing brand market. Specifically the "Polo Ralph Lauren Brand." Provide a brief market analysis that includes the state of the market before and after the differentiation, as well as the observed changes that resulted. Specifically, the following questions should be addressed:

• What type of market structure was the product or service in when the differentiation occurred?
• What was the differentiation? Describe specifically what the differentiation was and tell us what that means for rational business price and production decisions.
• What was the observed change in the equilibrium price in the market for that product?
• Evaluate whether the decision to differentiate the product was a good move for that business at that time.

Please provide sources where you got the information from. Also atleast 1 citation provided in the answer.
