leverage risk will not be priced.
CHAPTER 5 CAPITAL STRUCTURE AND RETURNS
1. Proposition II states that return on equity is an increasing function of leverage.
Debt increases the riskiness of the stock and hence equity shareholders demand
a higher return on their stocks. Modigliani and Miller (1958) define returns as the
sum of interest, preferred dividends, and stockholders’ income net of corporate
income taxes. They find a positive and linear relationship between leverage and
returns in their cross-sectional estimations in the electric utilities and oil and
gas sectors. Their work led to the development of different theories on capital
structure including the trade-off theory, pecking order theory, agency theory,
market timing theory, corporate control theory, and product cost theory.
2. The trade-off theory states that debt in a firm’s capital structure is beneficial to
equity investors as long as they are rewarded up to the point where the benefit
of the tax deductibility of interest offsets potential bankruptcy costs. The trade-
off theory consists of two parts: static trade-off theory and dynamic trade-off
theory. According to the static trade-off theory, firms select an optimal capital
structure that balances the advantages and disadvantages of using debt and
equity. Dynamic trade-off ...
