QUESTIONS chap12 3. How do the entry and exit of firms in a purely competitive industry affect resource flows and long‐run profits and losses? LO3 Answer: Entry and exit help to improve resource allocation. Firms that exit an industry due to low profits release their resources to be used more profitably in other industries. Firms that enter an industry chasing higher profits bring with them resources that were less profitably used in other industries. Both processes increase allocative efficiency
