Final answer:
b. 60, 40
Approximately 60 percent of a firm's profitability is explained by the industry in which it competes, and 40 percent by the firm's characteristics and actions.
Step-by-step explanation:
The question pertains to the factors that influence a firm's profitability.
Specifically, it asks what percentage of a firm's profitability is explained by the industry in which it competes, as opposed to the firm's own characteristics and actions.
While the question does not provide direct information, it is generally understood in strategic management that industry effects do play a significant role in determining firm profitability.
However, this effect is not as dominant as the characteristics and actions of the firm itself. Therefore, the answer that fits best with current business understanding is (b) 60 percent for the industry effect and 40 percent for the firm's own actions and characteristics.
This highlights the importance of strategic management and the competitive dynamics within an industry.
Research shows that approximately 70 percent of a firm's profitability is explained by the industry in which it competes, whereas 30 percent is explained by the firm's characteristics and actions.
