Market Structure and Profit Maximization

Because ease of entry is high in both perfect competition and monopolistic competition markets, and because making economic profits will always attract new producers (entrants), how do firms survive and make profits in those markets?

Provide an example of a firm or a small business from the real world that is surviving the dynamic nature of monopolistic competition and discuss some approaches they have used (or are currently using) to compete and survive in the market.

In addition, provide an example or a scenario from your personal (or professional) experience, an observation, a story that you have read, or an idea or a thought that you might have for practical, creative, and/or effective ways to minimize production costs in order to maximize profits.

Please review the following simple yet useful video that explains the concepts of costs and profits.
