Capital structure: Static tradeoff

12 important questions on Capital structure: Static tradeoff

What agency (costs) problems are there? (2)

- Asset substitution (risk shifting)
- Over-investment (empire building)

What is asset substitution (risk shifting)?

A conflict of interest between shareholders and bondholders
- Shareholders have more upside potential
- Bondholders have more downside risk

This problem is especially relevant if the risk of default is substantial

What is over-investment (empire building)?

A conflict of interest between shareholders and managers

- Managers might have a tendency to invest more than what is optimal from the shareholders' perspective
- High interest payments reduce free cash flows

What does the static tradeoff theory show?

- Trade-off between tax shields and the costs of financial distress
- Nowadays the trade-off typically includes agency costs

What do the empirical studies show? (3)

- Leverage regressions
- Financing decisions
- Mean reversion analysis

What are the relations between firm characteristics and optimal debt (5) (+ is high leverage & - is low leverage) based on theoretical predictions

1. Firm size (+)
2. Fixed assets (tangibility) (+)
3. Growth opportunities (-)
4. Profitability (+)
5. Firm risk (-)

What do studies typically find? (leverage regressions)

Positive effect on the debt ratio:
1. Firm size
2. Fixed assets

Negative effect on the debt ratio
3. Growth opportunities (market-to-book ratio)
4. Profitability (static trade-off theory got this one wrong)
5. Firm risk (earnings volatility)

What is 'Financing decisions: the debt-equity choice'?

- Do firms move towards a target debt ratio?
- Relation between debt-equity choice and the distance from a target debt ratio
--> How to measure the target debt ratio?
- Distinguish issue decisions from repurchase decisions
- On average, firms seem to move towards target, but slowly

How does mean reversion work?

Do firms move around a target debt ratio?
- Most empirical studies find some evidence for mean reversion behaviour

What is the conclusion on tests of the static tradeoff theory?

- Most predictions of the static tradeoff theory are consistent with patterns in the data
- However, some - like the relation between profitability and leverage - are not

How big are the tax benefits of debt?

A significant number of firms are surprisingly conservative in their use of debt
- Even firms with low expected costs of financial distress (large, profitable firms)

Given the tax benefits of debt: Why do they leave money on the table?

"Overall, tax incentives still do not seem to have a consistent, first-order effect on corporate capital structure" (which presents a puzzle as governments increasingly limit interest deductibility), (Hanlon & Heitzman, 2022)

What are the challenges with the static trade-off theory?

- Which factors, besides the cost of financial difficulty and agency costs, could reduce optimal debt ratios?
--> financial flexibility

- Or do we need a completely different theory?
--> Pecking order theory
