Managers aim to find a suitable capital structure policy to meet their goals, while researchers are curious about how firms choose sources of financing, making capital structure one of the most important fields of corporate finance Modern corporate capital structure theory originated with Modigliani and Miller’s (1958) irrelevance theorem The theory posits that in an efficient market with the absence of taxes, bankruptcy costs, and asymmetric information, the value of a firm is independent of its capital structure.

The Modigliani-Miller theorem posits that a firm's value is unaffected by its financing decisions under ideal conditions, serving as a cornerstone for capital structure studies However, the unrealistic assumptions of the Modigliani-Miller theorem have led to the development of alternative theories, such as the trade-off theory, which balances the benefits and costs of debt and equity financing The pecking order theory prioritizes internal financing due to asymmetric information, suggesting firms prefer debt over equity when external financing is necessary.

Ross (1977) initiated research on how a firm's capital structure choice can signal information to outside investors; issuing large debt levels signals a higher quality firm.

Capital structure determinants have been a subject of interest in finance, with early studies in 1974 and 1982 laying the theoretical groundwork Rajan and Zingales (1995) broadened the scope of this investigation to G-7 countries, with a focus on U.S firms, to understand capital structure decisions.

Recent empirical studies on capital structure determinants have been extended to various developed and developing countries, revealing both similarities and discrepancies in factors influencing firm financing decisions across different contexts This study aims to identify the key factors in capital structure decisions of U.S firms in recent times, particularly after the financial crisis, by updating data, applying improved panel data methodology, and using four kinds of leverage ratios.

In 1958, Franco Modigliani and Merton Miller proposed the Modigliani-Miller theorem, a cornerstone of modern corporate finance, addressing capital structure The theorem posits that in a perfect market, a firm's capital structure is irrelevant to its valuation, known as the capital structure irrelevance principle.

In reality, corporations operate in markets characterized by transaction costs, borrowing costs, taxes, asymmetric information, and agency costs, making a perfect market elusive To address these imperfections, alternative theories have been proposed by relaxing some assumptions in the Modigliani-Miller theorem.

Trade-off theory suggests firms aim for an optimal capital structure by balancing the costs and benefits of debt to maximize value Baxter (1967) and Kraus and Litzenberger (1973) proposed that taxable corporations should increase debt until the marginal cost equals the marginal benefit.

Firms obtain a tax advantage when borrowing because interest is tax deductible, but they also incur bankruptcy costs Companies using leverage need to pay interest on their borrowings, impacting earnings and cash flow, and increasing the probability of bankruptcy as borrowing increases The trade-off theory predicts that firms choose an optimal capital structure to balance tax benefits and costs of debt, substituting debt with equity or vice versa to maximize the company’s value.

Jensen and Meckling (1976) observed the widespread use of debt financing prior to interest tax subsidies, suggesting the presence of other significant, yet unrecognized, factors influencing capital structure They proposed two types of agency costs: conflicts between shareholders and managers, and conflicts between shareholders and creditors.

Managers sometimes prefer managing larger, more influential firms, which can reduce their incentive to prioritize shareholder benefits Increasing debt forces firms to make interest payments, thereby reducing free cash flow.

Agency costs arise between shareholders and creditors when shareholders undertake risky projects that benefit them but increase the risk for creditors Successful projects increase shareholder returns while lenders' benefits remain fixed, but project failure forces creditors to share in the loss This reduction in debt value due to risky projects is known as the agency cost of debt financing.

Studies on dynamic adjustment suggest that optimal and real capital structures often diverge due to market imperfections such as transaction costs, which impede instantaneous adjustments of real debts to desired levels Heinkel and Zechner (1989) propose that even small recapitalization costs can significantly alter a firm's debt ratio, while Leland emphasizes the role of agency costs of debt.

Kane (1984) and Brennan and Schwartz (1984) introduced dynamic models incorporating tax savings and bankruptcy costs These models examined continuous-time scenarios with uncertainty, taxes, and bankruptcy costs, assuming no transaction costs Firms quickly react to adverse shocks by rebalancing, maintaining high debt levels to maximize tax benefits Heider (2003) suggests companies specify a target capital structure and rapidly adjust towards it following changes in share prices or firm characteristics, using a partial adjustment model.

In 1961, Donaldson's analysis of corporations revealed a strong preference for internal funding, even over external sources, except for unavoidable funding surges Managers are hesitant to issue shares when external finance is necessary Financial officers acknowledged the opportune time to sell common stock, but reluctance persisted.

The pecking order theory, popularized by Stewart C Myers and Nicholas Majluf (1984), posits that information asymmetries in financial markets influence corporate financing decisions Managers, possessing superior information, may prefer issuing new common shares over debt when they believe their shares are overvalued Investors, rationally interpreting this signal, adjust share prices downward to compensate for their informational disadvantage Consequently, firms may avoid issuing stock even when it means foregoing positive NPV projects, acting in the best interest of existing shareholders.

Firm size is a significant determinant of capital structure, with small firms facing difficulties in raising long-term debt due to higher interest rates and inconvenient terms, leading them to rely on owned capital and retained earnings Conversely, large companies with economies of scale and bargaining power can access loans more easily and have more flexibility in choosing financing sources, including issuing shares and bonds The trade-off theory suggests a positive relationship between firm size and leverage, supported by findings that large firms often use long-term debt, while small firms do not.

Firm size serves as a proxy for the information available to outside investors Large firms disclose more information than small firms, as noted by Fama and Jensen (1983) Large firms are more capable of issuing equity compared to their smaller counterparts Small firms, typically managed by a small group, tend to avoid intrusion from outside entities.

Small firms prioritize retained earnings for financing and prefer debt over issuing equity when internal funds are insufficient, aligning with pecking order theory Research indicates that small firms only seek external resources after exhausting internal funds Their motivation for borrowing is primarily to meet financial needs rather than to optimize capital structure.

Tangible assets increase a firm's liquidation value because they are easy to identify and measure, making them suitable as collateral for debt Companies with large tangible assets can more easily approach creditors, as these assets serve as a guarantee in case of bankruptcy Trade-off theory suggests that firms will be more leveraged when they possess more tangible assets.

Firms with more tangible assets are less affected by information asymmetry and agency costs Pecking order theory and agency theory predict that these firms can borrow more debt Prior studies show mixed results regarding the positive relationship between capital structure and firms' asset structure.

Firms with larger tangible assets possess a stable source of returns, providing internal funds and discouraging external financing Pecking order theory predicts a negative relationship between leverage and tangibility.

Degeyse et al (2010) established a positive relationship between debt and tangibility, noting that the positive impact on total debt was primarily from long-term debt, as short-term debt is negatively affected by collateral This may be due to banks charging higher interest rates on short-term debt compared to long-term debt This aligns with the maturity matching principle, where long-term assets are financed with long-term financing and short-term assets with short-term funds.

The relationship between profitability and capital structure remains a conflict in corporate finance The pecking order theory suggests firms prioritize internal financing, using external funds only when internal resources are exhausted Studies by Al-Sakran (2001), Fama and French (2002), and others consistently show a negative relationship between profitability and leverage, supporting the pecking order theory.

Firms cannot always enjoy tax shield benefits from increased leverage; highly profitable firms often incorporate less debt when making capital structure decisions.

The relationship between growth and capital structure remains ambiguous Major previous studies generally favor a negative relationship between growth opportunities and the leverage of firms.

Another school of thought supports a positive relationship between growth and leverage, arguing that managers initially use debt for capital but reduce it as projects become profitable Modigliani and Miller (1958) found a positive correlation between leverage and growth, while Myers (1977) suggested high-growth companies avoid risky debt, potentially missing valuable investments Pandey (2001) demonstrated that rapidly growing firms need to expand fixed assets, increasing their demand for funds and retained earnings; his examination of Malaysian firms from 1994 to 1999 revealed a significant relationship between growth and debt ratios, with firms favoring short-term debt to finance growth.

DeAngelo and Masulis (1980) proposed a model of optimal capital structure that combines the impact of corporate taxes, personal taxes, and non-debt tax shields They posited that tax deductions for depreciation and investment tax credits are tax benefits of debt financing Firms with a large amount of non-debt tax shields will enjoy more benefit and, as a result, borrow more.

According to trade-off theory, firms facing higher taxes on earnings tend to increase leverage Increased borrowing leads to a greater value of debt tax shields, as suggested by Myers (1984).

Empirical research supports the relationship between taxes and leverage, although it's not the most prominent factor Studies by Bauer (2004) and Chi (2013) indicate a positive influence of taxes on debt usage Non-debt tax shields, such as depreciation, often exhibit a negative relationship with leverage, aligning with trade-off theory, as observed by Bauer (2004), Huang and Song (2002), and Cortez and Susanto (2012).

Firms face financial and business risks, where business risk, indicated by earnings volatility, influences capital structure Higher risk increases financial distress costs, leading riskier firms to reduce leverage to avoid bankruptcy, as predicted by trade-off theory Volatile cash flows from cyclical or seasonal businesses diminish the tax advantages of debt, supporting a negative relationship between volatility and leverage Firms with volatile cash flows also avoid large fixed debt commitments.

Panel data controls for unobservable individual heterogeneity by allowing for entity-specific variables, addressing issues like multicollinearity in time series data.

Descriptive statistics were initially employed to illustrate the characteristics of U.S firms Subsequently, correlation analysis provided an overview of the relationships between each pair of variables Finally, linear regression was performed as the primary analysis to identify the key factors explaining capital structure.

Due to many companies lacking data, the dataset is constructed as an unbalanced panel To address this, several estimating techniques can be used This paper will employ the two most popular estimators: random effects and fixed effects.

Fixed-effects models analyze relationships between explanatory and dependent variables within an entity, eliminating time-invariant characteristics to assess the net effect of explanatory variables Unlike fixed-effects models, random-effects models assume variation across entities is random and uncorrelated to explanatory variables, allowing time-invariant variables to have an effect Regressions were conducted using both fixed-effects (FEM) and random-effects models (REM) on independent variables without dummy variables, and the Hausman test will determine the appropriate model.

Firms issue various securities like short-term debt, long-term debt, and common stock to raise funds Leverage in capital structure research refers to financial leverage, not operating or total leverage Total debt to capital ratio, in book or market value, is the most relevant leverage definition Other measures include long-term and short-term debt ratios to the book value of capital.

Profitability is assessed through various financial ratios Operating income over sales and operating income over total assets are common metrics, as seen in Frank and Goyal (2009), who utilized operating income before depreciation Other studies, such as Michaelas, Chittenden, and Poutziouris (1998), Han-Suk Song (2005), and Sogorb-Mira (2005), employ the ratio of earnings before interest and taxes (EBIT) to total assets Hall, Hutchinson, and Michaelas (2000) used the ratio of EBT over sales, while Klapper, Sarria-Allende, and Zaidi (2006), and Degryse, Goeji, and Kapper (2009) opted for returns on assets This study uses returns on assets as an indicator of profitability.

Firm size is often measured by sales, number of employees, or total assets, with the log of total assets commonly used as a proxy Growth, reflecting changes in business operations, is an influential determinant of capital structure The market-to-book asset ratio is a common proxy for growth, while capital expenditure and changes in log assets are also popular Percentage change in total assets or sales over previous years are also used to measure growth.

This study investigates realized values as a proxy for growth when the capital structure decision was made, focusing on actual growth rather than potential opportunities Growth is measured by the percentage change of sales from the previous year, not by the market-to-book asset ratio.

Tangibility is calculated as gross property, plant, and equipment over total assets Non-debt tax shields, such as depreciation and investment tax credits, are considered a tax benefit of debt financing Indicators for non-debt tax shields often include the ratios of depreciation over total assets, investment tax credits over total assets, and a direct estimate of non-debt tax shields over total assets; in this study, the ratio of depreciation over total assets will be used.

To measure the influence of risk on capital structure, the volatility of income is often used In this study, a three-year rolling standard deviation of returns on assets is employed The business risk of each period equals the standard deviation of ROA of the last period, this period, and the next period.

U.S companies, on average, utilize high leverage, with the average Total Debt to Market Value of Capital (TDM) ratio at 45.93% and the average Total Debt to Book Value of Capital (TDB) at 34.89% Market value ratios indicate higher leverage compared to book value ratios Long-term debt is a significant source of capital for companies, as suggested by the average Long-term Debt to Book Value of Capital (LDB) ratio of 30.27%, while the average Short-term Debt to Book Value of Capital (SDB) ratio is 5.06%.

Companies exhibit significant differences in debt policy, as evidenced by the standard deviations of total debt to book assets (TDB), total debt to market assets (TDM), long-term debt to book assets (LDB), and short-term debt to book assets (SDB), which are 25.68%, 22.36%, 18.99%, and 13.21%, respectively; some firms have a minimum debt ratio of zero and do not borrow, while others fund up to 92.31% of their capital through borrowings.

Firm size, measured by the log of total assets, positively correlates with all measures of capital structure, especially total debt to market value of capital, aligning with trade-off theory Firm size is negatively correlated with other firms’ characteristics, except for tangibility, suggesting that larger U.S firms tend to have a higher proportion of tangible assets.

Firm growth, measured by changes in sales, is negatively related to most debt ratios, supporting the trade-off theory that high-growth firms prefer equity Firm growth also has a negative correlation with profitability, size, tangibility, and non-debt tax shields, and a weak negative correlation with risk Business risk, measured by the standard deviation of returns on assets, is negatively correlated with debt ratios using the book value of capital and positively correlated with debt ratios using the market value of capital This aligns with trade-off theory, suggesting firms reduce borrowings when facing higher expected financial distress costs due to high risk Risk moves inversely with profitability, while firm size moves in the same direction as other factors.

Companies paying higher taxes tend to borrow more to enjoy the benefits of a tax shield, as suggested by the trade-off theory Non-debt tax shields are negatively correlated with most leverage ratios, except for short-term leverage, although the correlation is quite small Non-debt tax shields move in an inverse direction with risk and tangibility, while moving in the same direction with other factors.

Tangibility of assets is positively correlated with most debt ratios, except the short-term debt ratio, as predicted by theories like pecking order theory, trade-off theory, and agency theory Firms with a large portion of tangible assets are more easily able to secure debt financing.

The TDB model reveals an overall R-squared of 0.0075, indicating that profitability, firm size, growth, tangibility, non-debt tax shield, and business risk explain 0.75% of the variability in capital structure, measured by Total Debt to Book Value of Capital.

The TDM model's R-squared of 0.0687 indicates that selected firm characteristics—profitability, firm size, growth, tangibility, non-debt tax shield, and business risk—explain 6.8% of the changes in leverage, measured by Total Debt to Market Value of Capital.

The overall R-squared value of 0.0074 in the LDB model suggests that firm characteristics, including profitability, size, growth, tangibility, non-debt tax shield, and business risk, explain only 0.74% of the changes in the proportion of long-term debt used in total capital, as measured by the Long-term Debt to Book value of capital ratio.

The TDM model with random effects shows an overall R-squared of 0.0076, indicating that selected firm characteristics such as profitability, firm size, growth, tangibility, non-debt tax shield, and business risk explain 0.76% of the changes in the proportion of short-term debt used in total capital, as measured by Short-term Debt to book value of capital.

Regression analysis reveals a significant negative correlation between profitability, measured by return on assets, and debt ratios, particularly total debt to book value of capital and long-term debt ratios, suggesting that profitable firms tend to borrow less, except for short-term debt.

According to pecking-order theory, firms prioritize retained earnings over external financing for capital, aligning with Myers and Majluf (1984) This finding supports the preference for internal funds in profitable firms.

U.S firms' size and debt ratios move in the same direction, with firm size, measured by the log of total assets, showing a significant positive relationship with all types of leverage (\$\beta\$ significant at the 1% level) Larger firms generally utilize more debt, including total, short-term, and long-term debt, with a statistically significant relationship between firm size and leverage, whether based on book or market value of capital Firm growth, measured by sales growth, has an insignificant relationship with capital structures; the relationships between growth and various debt-to-capital ratios are mixed (positive for Total Debt to Book Value, Short-term Debt to Book Value, and negative for Total Debt to Market Value, Long-term Debt to Book Value), but all are statistically insignificant, suggesting growth is not a determinant of capital structure.

Asset structure significantly influences a firm's capital structure, with a larger proportion of tangible assets generally leading to higher leverage Companies tend to utilize more long-term debt when possessing substantial tangible assets, while simultaneously decreasing their reliance on short-term debt This aligns with the maturity matching principle, advocating for financing long-term assets with long-term debt and short-term assets with short-term funds This finding supports both trade-off and agency theories, which anticipate a positive correlation between asset tangibility and leverage, and is also consistent with the pecking-order theory, which predicts both positive and negative relationships between leverage and tangibility.

Profitable firms tend to be less leveraged, as measured by total debt to market value and book value of capital, and long-term debt to book value of the capital structure This supports pecking order theory because firms prefer retained earnings over outside funds for investment Profitability, however, does not significantly influence short-term debt decisions.

Non-debt tax shields have an ambiguous impact on capital structure The relationship between non-debt tax shields and capital structure is positive but insignificant This finding moderately supports the theory that firms with large non-debt tax shields borrow more.

Firm growth exhibits a negative but statistically insignificant relationship with capital structure Consequently, changes in sales, as a measure of firm growth, do not determine capital structure decisions.

This study provides evidence consistent with pecking-order theory, indicating a positive relationship between asset tangibility and financial leverage, and a negative relationship between profitability and financial leverage The findings moderately support trade-off theory's prediction of a negative relationship between non-debt tax shields and leverage, as well as between business risk and leverage The trade-off theory's suggestion of a positive relationship between asset tangibility and financial leverage is also confirmed Finally, agency theory's prediction of a negative relationship between growth opportunities and leverage is moderately supported by a negative, though insignificant, relationship.

This study concentrates on the six most popular and important factors recommended by vast literature It does not include some relevant firms’ characteristics, such as R&D activities, manager behaviors, and state ownership, that are recommended from other empirical studies Other factors from the economy can also be included.

The study omits industry average growth rate, inflation rate, and interest rate due to limited data availability and the extensive process of collecting data from diverse and un-unified sources.

While a five-year research period with 24 quarters offers sufficient time, it remains short compared to credible worldwide studies, such as Frank and Goyal's (2009) study spanning over 50 years The 2010-2015 period is unique due to the economic recovery from the financial crisis, leading to numerous changes affecting companies' capital structure decisions Consequently, results may differ from studies conducted in different or longer periods.

The United States is a developed financial market, so results may not be directly applicable to developing markets Studies in developing and emerging markets have found some differences in capital structure compared to studies in developed markets Careful consideration is needed when choosing proxies for factors like growth, as different proxies such as changes in sales versus market-to-book ratios can yield varying relationships with capital structure Studies using market-to-book ratios often find a negative relationship between capital structure and growth, while those using changes in sales may find an ambiguous relationship.

The study utilizes a sample of firms covering over 90% of the U.S public stock market capitalization, including three groups to ensure generality The first group is the S\&P 500, comprising 500 large companies with common stock listed on the NYSE or NASDAQ The second group is the S\&P 400 (mid-cap firm), which includes investors with a benchmark for mid-sized companies to reflect the distinctive risk and return characteristics of this market segment The third group is the S\&P 600, which includes the small-cap segment.

Among 1,500 U.S market companies, only those meeting specific requirements are included in the analysis For example, companies lacking data for at least two consecutive years are excluded due to lagged variable specifications.

To mitigate the impact of the financial crisis on capital structure, the data sample focuses on U.S companies in the post-financial crisis period, specifically from Q1 2010 to Q2 2016 The final panel data set comprises approximately 39,000 observations.

Panel data combines cross-sectional and time series data, helping to identify individual and time effects that pure cross-sectional or time series data cannot This is especially necessary when analyzing the effects of many factors on companies' capital structure over multiple periods.

Panel data controls for unobservable individual heterogeneity by allowing for entity-specific variables, addressing issues like multicollinearity in time series data.

Descriptive statistics were initially employed to illustrate the characteristics of U.S firms Subsequently, correlation analysis provided an overview of the relationships between each pair of variables Finally, linear regression was performed as the primary analysis to identify the key factors explaining capital structure.

Due to many companies lacking data, the dataset is constructed as an unbalanced panel To address this, several estimating techniques can be used This paper will employ the two most popular estimators: random effects and fixed effects.

Fixed-effects models analyze relationships between explanatory and dependent variables within an entity, eliminating time-invariant characteristics to assess the net effect of explanatory variables Unlike fixed-effects models, random-effects models assume variation across entities is random and uncorrelated to explanatory variables, allowing time-invariant variables to have an effect Regressions are run with both fixed-effects (FEM) and random-effects models (REM) on independent variables, and the Hausman test is used to examine the model.

Firms issue various securities like short-term debt, long-term debt, and common stock to raise funds Leverage in capital structure research refers to financial leverage, specifically the ratio of total debt to capital Relevant leverage definitions include total debt to capital (book or market value) and long-term/short-term debt to book value of capital.
