Review Questions

• How do different types of market structures affect pricing strategies and consumer choices?
  • Different types of market structures affect pricing strategies significantly. In a monopoly, the single firm sets prices higher due to lack of competition. In contrast, under perfect competition, firms have little control over prices because they must compete on price alone. Understanding these dynamics helps explain how consumers make choices based on available options and pricing levels across various markets.
• Discuss how the Sherman Antitrust Act addresses issues within various market structures and its impact on competition.
  • The Sherman Antitrust Act was designed to combat anti-competitive behaviors that arise in different market structures, particularly in monopolies and oligopolies. By prohibiting practices like price-fixing and monopolization, the act aims to foster fair competition. Its enforcement has led to significant legal actions against large corporations, ensuring a level playing field in industries that may otherwise limit consumer choices.
• Evaluate the long-term implications of changing market structures on economic growth and consumer welfare.
  • Changing market structures can have profound long-term implications for economic growth and consumer welfare. As markets evolve from monopolistic or oligopolistic forms toward more competitive structures, consumers typically benefit from lower prices and increased innovation. However, if companies consolidate power again or engage in anti-competitive practices, it could stifle growth and harm consumer interests. Evaluating these dynamics is essential for understanding the broader economic landscape.
