Review Questions

• How does the marginal cost of capital influence a company's decision-making regarding new investments?
  • The marginal cost of capital plays a crucial role in determining whether a company should pursue new investments. By comparing the expected return on an investment to its marginal cost of capital, firms can assess if the potential returns justify the expense. If the expected return exceeds the marginal cost, it signals that the investment could enhance value; otherwise, it may be better to forgo it.
• Analyze how changes in market conditions affect a company's marginal cost of capital.
  • Market conditions such as fluctuating interest rates or shifts in investor confidence can significantly impact a company's marginal cost of capital. For example, if interest rates rise, the cost of debt increases, raising the overall marginal cost. Conversely, during periods of economic stability with low rates, firms may find it cheaper to finance projects. Understanding these dynamics helps firms adjust their financing strategies effectively.
