What is the term for obstacles that determine how easily a firm can leave an industry?

The term for obstacles that determine how easily a firm can leave an industry is "Exit Barriers." Exit barriers are the factors that make it difficult or costly for a company to discontinue its operations in an industry or market. These can include financial commitments, contractual obligations, high emotional costs, loss of reputation, or critical assets that cannot easily be liquidated. Understanding exit barriers is crucial for strategic management because they affect a firm’s ability to respond to poor market conditions or decreased profitability effectively.

While mobility barriers refer to obstacles that impact a firm's ability to move resources or capabilities between industries, entry barriers pertain to the challenges and costs of starting a business in a given market. Market barriers would involve broader issues that affect competition within a market but do not specifically address the challenges related to exiting. Therefore, "Exit Barriers" is the most accurate term in the context of a firm's ability to leave an industry.
