Final answer:
Option A (I, II, and III) is the correct choice because for maximizing a firm's value to be equal to minimizing the weighted average cost of capital, all the three conditions must be met: a settled investment policy, no taxes, and new debt issuance not affecting existing debt's market value.
Step-by-step explanation:
The question pertains to the relationship between a firm's policy of maximizing its value and minimizing its weighted average cost of capital (WACC). A firm that maximizes its value does so by investing in projects that earn a rate of return higher than the cost of capital, effectively lowering the WACC. However, for the policy of maximizing the value of the firm to be synonymous with minimizing WACC, certain conditions have to be met: the firm's investment policy must be fixed (I), there should be no taxes impacting the cost of capital (II), and the issuance of new debt should not affect the value of existing debt (III).
When perfectly competitive firms maximize their profits by producing where price (P) equals marginal cost (MC), they achieve a state where the benefits to consumers (price they are willing to pay) match the costs to society of producing additional units (marginal costs). This ensures that allocative efficiency is maintained, meaning that resources are allocated in the most efficient manner, maximizing societal benefit.
The correct answer to the question would be Option A, which includes all three statements (I, II, and III), aligning with the condition that the policy of maximizing the firm's value is the same as the policy of minimizing the WACC, assuming all given conditions are in place.
