Capital Structure Agency: How Capital Structure Aligns or Conflicts with the Interests of Managers and Shareholders

1. What is Capital Structure and Why Does It Matter?

capital structure is the mix of debt and equity that a firm uses to finance its operations and growth. It affects the firm's cost of capital, risk, profitability, and value. Therefore, it is an important decision for managers and shareholders, who may have different preferences and incentives regarding the optimal capital structure. In this section, we will explore the concept of capital structure agency, which refers to the potential conflict of interest between managers and shareholders over the choice of capital structure. We will also discuss how capital structure can align or conflict with the interests of managers and shareholders, and what factors can influence their preferences. Some of the topics that we will cover are:

1. The trade-off theory of capital structure: This theory suggests that firms balance the benefits and costs of debt and equity financing. The main benefit of debt is the tax shield, which reduces the firm's taxable income and increases its after-tax cash flow. The main cost of debt is the financial distress, which occurs when the firm has difficulty meeting its debt obligations and faces bankruptcy risk. Managers and shareholders may have different views on the optimal trade-off, depending on their risk aversion, time horizon, and personal tax situation. For example, managers may prefer less debt than shareholders, because they are more exposed to the downside risk of financial distress and may lose their jobs, reputation, and human capital. Shareholders, on the other hand, may prefer more debt than managers, because they can diversify their portfolio risk and benefit from the tax shield and the discipline effect of debt, which reduces the agency cost of free cash flow.

2. The pecking order theory of capital structure: This theory suggests that firms follow a hierarchy of financing sources, preferring internal funds over external funds, and debt over equity. The main reason for this preference is the information asymmetry between managers and investors, which leads to adverse selection and signaling problems. Managers have more information about the firm's value and prospects than investors, and they may use this information to their advantage. For example, managers may issue equity when they think the firm is overvalued, and buy back equity when they think the firm is undervalued. This implies that equity issuance is a negative signal of the firm's quality, and investors will demand a higher return to invest in the firm's equity. Therefore, managers prefer to use internal funds, such as retained earnings or depreciation, to finance the firm's investments, and avoid issuing equity unless they have no other choice. Shareholders may also prefer the pecking order, because it reduces the information costs and the dilution of their ownership and control.

3. The market timing theory of capital structure: This theory suggests that firms adjust their capital structure in response to the market conditions and the relative valuation of debt and equity. Managers may try to time the market by issuing equity when the stock price is high, and repurchasing equity when the stock price is low. They may also issue debt when the interest rate is low, and retire debt when the interest rate is high. The main motivation for market timing is to maximize the firm's value and minimize the cost of capital. Shareholders may also benefit from market timing, because it increases the firm's cash flow and reduces the risk of financial distress. However, market timing may also have some drawbacks, such as transaction costs, market inefficiency, and behavioral biases. For example, managers may be overconfident or overoptimistic about the firm's future performance, and issue too much equity or debt at the wrong time, resulting in suboptimal capital structure and lower firm value.

## Sources and types of agency conflicts

Agency conflicts arise when the managers have more information and control over the firm's operations and finances than the shareholders, and when their actions are not fully observable or verifiable by the shareholders. This creates an information asymmetry and a moral hazard problem, where the managers may exploit their advantage and act in ways that benefit themselves, but harm the shareholders. Some examples of agency conflicts are:

- Overinvestment and underinvestment. The managers may invest too much or too little in projects that have positive net present value (NPV) for the shareholders, depending on their risk aversion, personal wealth, and career concerns. For instance, the managers may overinvest in risky or negative NPV projects to increase their power, reputation, or compensation, or to pursue their personal interests or pet projects. Alternatively, the managers may underinvest in positive NPV projects to avoid risk, debt, or dilution of their ownership, or to accumulate free cash flow for their own use.

- Dividend policy. The managers may pay too much or too little dividends to the shareholders, depending on their liquidity needs, tax status, and signaling motives. For instance, the managers may pay excessive dividends to please the shareholders and increase the stock price, even if it means sacrificing profitable investment opportunities or increasing the borrowing costs. Alternatively, the managers may pay insufficient dividends to retain more cash for their own discretion, or to signal confidence in the firm's future prospects, even if it means reducing the shareholders' wealth or increasing the agency costs of free cash flow.

- Debt policy. The managers may issue too much or too little debt to finance the firm's activities, depending on their leverage preferences, tax benefits, and bankruptcy costs. For instance, the managers may issue excessive debt to take advantage of the tax shield, to discipline themselves from wasting free cash flow, or to deter hostile takeovers. Alternatively, the managers may issue insufficient debt to avoid financial distress, to maintain financial flexibility, or to preserve their control and private benefits.

These agency conflicts can reduce the firm's value and performance, as the managers may make suboptimal decisions that deviate from the shareholders' optimal capital structure. The shareholders may incur agency costs to monitor, control, or influence the managers' behavior, or to bear the consequences of the managers' actions. The magnitude of these agency costs depends on the severity of the agency conflicts, the nature of the firm's assets and operations, and the characteristics of the capital markets.

## Potential solutions and mechanisms

To align the interests of managers and shareholders, and to reduce the agency costs of capital structure, several solutions and mechanisms can be employed, such as:

- Incentive contracts. The shareholders can design compensation schemes that link the managers' pay to the firm's performance, such as stock options, bonuses, or profit-sharing plans. These schemes can motivate the managers to maximize the firm's value and the shareholders' wealth, and to avoid actions that reduce the firm's profitability or increase its risk. However, these schemes may also create new problems, such as short-termism, manipulation, or excessive risk-taking, and may be costly or difficult to implement or monitor.

- Monitoring and governance. The shareholders can appoint board of directors, auditors, or other external parties to oversee, evaluate, or advise the managers' decisions and actions, and to ensure their accountability and transparency. These parties can provide valuable information, feedback, or guidance to the managers, and can discipline or replace them if they perform poorly or act against the shareholders' interest. However, these parties may also have their own conflicts of interest, biases, or limitations, and may be ineffective or inefficient in fulfilling their roles or responsibilities.

- Market forces. The shareholders can rely on the market prices, signals, or pressures to influence the managers' behavior, such as the stock price, the cost of capital, the dividend policy, or the threat of takeover. These market forces can reflect the shareholders' expectations, preferences, or demands, and can reward or punish the managers for their performance or actions. However, these market forces may also be distorted, noisy, or incomplete, and may not capture the true value or potential of the firm or its projects.

3. How Managers Choose the Optimal Mix of Debt and Equity?

Capital structure decisions play a crucial role in determining the optimal mix of debt and equity for a company. Managers are faced with the task of balancing the benefits and risks associated with different financing options. From the perspective of managers, the choice of capital structure can align or conflict with the interests of both shareholders and themselves.

1. Debt Financing: One approach to capital structure is to rely more heavily on debt financing. This can provide several advantages, such as tax benefits from interest deductions and lower cost of capital compared to equity. However, excessive debt can increase financial risk and limit the company's flexibility in times of economic downturns.

2. Equity Financing: On the other hand, managers may choose to raise capital through equity financing. This involves issuing shares to investors in exchange for ownership in the company. Equity financing can provide a cushion against financial distress and reduce the burden of debt repayment. However, it dilutes existing shareholders' ownership and may lead to loss of control for managers.

3. Trade-Off Theory: The trade-off theory suggests that managers aim to strike a balance between debt and equity to maximize the value of the firm. By considering the costs and benefits of each financing option, managers can determine the optimal capital structure that minimizes the overall cost of capital while maximizing shareholder value.

4. Pecking Order Theory: Another perspective is the pecking order theory, which suggests that managers prefer internal financing (retained earnings) over external financing (debt or equity). This theory implies that managers prioritize using internally generated funds before resorting to external sources, as it avoids information asymmetry and signaling problems.

5. Agency Costs: Capital structure decisions can also be influenced by agency costs, which arise from conflicts of interest between managers and shareholders. Managers may have incentives to pursue their own interests rather than maximizing shareholder wealth. Debt financing can act as a disciplinary mechanism by imposing constraints on managers' actions, reducing agency costs.

6. Examples: For instance, a company in a stable industry with predictable cash flows may opt for higher debt levels to take advantage of tax shields and lower cost of capital. Conversely, a high-growth startup may rely more on equity financing to fund its expansion plans without the burden of debt repayment.

Capital structure decisions involve a careful evaluation of the benefits and risks associated with debt and equity financing. Managers must consider various perspectives, such as the trade-off theory, pecking order theory, and agency costs, to determine the optimal mix that aligns with the interests of both shareholders and themselves.

4. How Debt and Equity Can Create Agency Problems and Costs?

One of the main challenges in corporate finance is to design a capital structure that aligns the interests of managers and shareholders, while minimizing the costs of financing. However, this is not always easy, as different sources of funding may create different incentives and conflicts for the parties involved. In this section, we will explore how debt and equity can create agency problems and costs, and how they can affect the value of the firm.

Some of the factors that can create agency problems and costs are:

1. The risk-shifting problem: This occurs when managers have an incentive to take on more risk than shareholders would prefer, because they benefit from the upside potential of risky projects, while the downside risk is borne by the debt holders. For example, suppose a firm has a lot of debt and is facing financial distress. The managers may decide to invest in a project that has a high probability of failure, but also a high payoff if successful. This way, they can either save the firm or walk away with nothing, while the debt holders are left with a worthless claim. This problem can reduce the value of the firm, as debt holders will demand a higher interest rate to compensate for the risk, and shareholders will lose some of their expected returns.

2. The underinvestment problem: This occurs when managers have an incentive to reject positive net present value (NPV) projects, because they do not capture the full benefits of the investment, while they bear the full costs. For example, suppose a firm has a lot of debt and is considering a project that requires an initial outlay of $100, and has a present value of $120. The project has a positive NPV of $20, and should be accepted. However, if the firm undertakes the project, the debt holders will receive $120 at maturity, while the shareholders will receive nothing. Therefore, the managers may decide to reject the project, even though it increases the value of the firm. This problem can also reduce the value of the firm, as it leads to underinvestment and missed opportunities.

3. The free cash flow problem: This occurs when managers have an incentive to waste or misuse the excess cash flow that the firm generates, rather than return it to the shareholders or invest it in profitable projects. For example, suppose a firm has a lot of equity and generates more cash than it needs to fund its operations and growth opportunities. The managers may decide to use the cash for personal benefits, such as excessive salaries, perks, or empire building, rather than pay dividends or repurchase shares. This problem can also reduce the value of the firm, as it lowers the returns to the shareholders and creates inefficiencies.

These agency problems and costs can be mitigated by various mechanisms, such as contracts, covenants, monitoring, incentives, signaling, and corporate governance. However, these mechanisms are not perfect, and may entail their own costs and trade-offs. Therefore, the optimal capital structure of a firm depends on the balance between the benefits and costs of debt and equity, and the specific characteristics of the firm and its environment.

5. What Empirical Studies Say About the Effects of Capital Structure on Firm Performance and Value?

One of the most important and debated topics in corporate finance is how firms choose their capital structure, or the mix of debt and equity financing. capital structure affects both the risk and the return of a firm, and therefore has implications for its performance and value. However, there is no consensus on the optimal capital structure for a firm, and different empirical studies have found different results depending on the context, methodology, and assumptions. In this section, we will review some of the main findings from the empirical literature on the effects of capital structure on firm performance and value, and discuss the implications for capital structure agency, or the potential conflicts of interest between managers and shareholders regarding the financing decisions.

Some of the key insights from the empirical studies are:

1. The trade-off theory suggests that firms balance the benefits and costs of debt financing. The main benefit of debt is the tax shield, or the reduction in taxable income due to interest payments. The main costs of debt are the financial distress costs, or the costs associated with bankruptcy or default, and the agency costs, or the costs arising from the conflicts of interest between debt holders and equity holders. According to the trade-off theory, firms should choose a capital structure that maximizes their value by minimizing their weighted average cost of capital (WACC). Empirical studies have found some support for the trade-off theory, especially for large and mature firms that have stable cash flows and low growth opportunities. For example, Graham and Harvey (2001) surveyed CFOs of US firms and found that most of them consider the tax benefits and the financial distress costs of debt financing decisions. However, the trade-off theory does not explain why some firms have very low or zero debt levels, or why some firms adjust their capital structure more frequently than others.

2. The pecking order theory suggests that firms prefer internal financing over external financing, and debt over equity when external financing is needed. The main reason for this preference is the information asymmetry, or the difference in information between managers and investors. Managers have more information about the true value and prospects of the firm, and therefore may issue equity when the firm is overvalued, or avoid issuing equity when the firm is undervalued. This creates a signaling problem, or a situation where the actions of managers convey information to the market that affects the firm's value. According to the pecking order theory, firms should avoid issuing equity unless they have exhausted their internal funds and debt capacity, and should use debt as a signal of quality and confidence. Empirical studies have found some support for the pecking order theory, especially for small and young firms that have high information asymmetry and high growth opportunities. For example, Myers and Majluf (1984) showed that firms with high growth opportunities and low debt ratios tend to issue debt rather than equity when they need external financing, and that equity issues are associated with negative stock price reactions.

3. The market timing theory suggests that firms take advantage of the fluctuations in the market conditions and the mispricing of their securities when making financing decisions. The main assumption of this theory is that managers are able to time the market, or to issue securities when they are overpriced and repurchase them when they are underpriced. According to the market timing theory, firms should choose a capital structure that reflects the cumulative outcome of their past market timing attempts, and not their long-term target or optimal capital structure. Empirical studies have found some support for the market timing theory, especially for firms that have high market-to-book ratios and high stock price volatility. For example, Baker and Wurgler (2002) showed that firms with high market-to-book ratios tend to issue equity and reduce their leverage, and that the historical market-to-book ratios explain a large part of the variation in the capital structure across firms and over time.

6. Key Takeaways and Implications for Managers and Shareholders

In this section, we will summarize the main points of the blog and discuss the implications of capital structure agency for managers and shareholders. Capital structure agency refers to the potential conflict of interest between the owners and the managers of a firm regarding the optimal mix of debt and equity financing. We will examine how different factors, such as the level of debt, the type of debt, the ownership structure, the corporate governance, and the market conditions, can affect the alignment or misalignment of the interests of the two parties. We will also provide some recommendations for managers and shareholders on how to mitigate the agency costs of capital structure and maximize the value of the firm.

Some of the key takeaways and implications of capital structure agency are:

- The level of debt can have both positive and negative effects on the agency problem. On one hand, debt can reduce the free cash flow available to managers and discipline them to invest in positive net present value (NPV) projects. On the other hand, debt can increase the risk of financial distress and bankruptcy, and induce managers to take excessive or insufficient risks, depending on their risk preferences and incentives. Therefore, managers and shareholders should balance the benefits and costs of debt and choose the optimal debt ratio that maximizes the firm's value.

- The type of debt can also influence the agency problem. short-term debt can increase the monitoring and pressure from creditors, but also increase the refinancing risk and the sensitivity to market fluctuations. long-term debt can reduce the refinancing risk and the volatility of cash flows, but also reduce the flexibility and adaptability of the firm. Moreover, different types of debt can have different tax implications, liquidity implications, and signaling effects. Therefore, managers and shareholders should consider the trade-offs and complementarities of different types of debt and choose the optimal debt maturity and structure that suits the firm's characteristics and needs.

- The ownership structure can affect the agency problem by influencing the degree of control and influence that shareholders have over managers. Concentrated ownership can increase the monitoring and alignment of managers, but also increase the entrenchment and expropriation of minority shareholders. Dispersed ownership can reduce the entrenchment and expropriation of managers, but also reduce the monitoring and alignment of shareholders. Therefore, managers and shareholders should consider the costs and benefits of different ownership structures and choose the optimal ownership concentration and distribution that enhances the firm's performance and value.

- The corporate governance can affect the agency problem by influencing the mechanisms and incentives that regulate the relationship between managers and shareholders. effective corporate governance can reduce the agency costs of capital structure by aligning the interests and goals of the two parties, enhancing the accountability and transparency of managers, and improving the efficiency and quality of decision-making. Therefore, managers and shareholders should adopt and implement good corporate governance practices and standards that foster the trust and cooperation between the two parties and create value for the firm and its stakeholders.

- The market conditions can affect the agency problem by influencing the opportunities and constraints that managers and shareholders face. favorable market conditions can increase the profitability and growth potential of the firm, but also increase the temptation and opportunity for managers to pursue their own interests at the expense of shareholders. Adverse market conditions can increase the financial distress and survival risk of the firm, but also increase the pressure and motivation for managers to act in the best interest of shareholders. Therefore, managers and shareholders should monitor and respond to the changes and challenges in the market environment and adjust their capital structure and strategies accordingly.
