Agency costs,taxes and debt: The UK evidence

This paper provides an empirical examination of the impact of the corporation tax and agency costs on firms' capital structure decisions. Our evidence suggests that the agency costs are the main determinants of corporate borrowing. Consistent with the agency theory, we find that firms that have fewer growth options have more debt in their capital structure. Moreover, our results show that debt mitigates the free cash flow problem and that firms that are more likely to be diversified and less prone to bankruptcy are highly geared. the negative effect of insider shareholding on leverage disappears, however; when all the agency mechanisms are accounted for. In addition, we find that, in the long run, companies that are tax exhausted exhibit significantly lower debt ratios than tax-paying firms. However, in the short run, firms' capital structure decisions are not affected by taxation.     

Tax policies and agency costs

We show that when large corporations are subject to a different tax system than smaller firms, the agency cost of under- and overinvestment is significantly altered. In contrast to the findings in the literature, the gap between the first- and second-best investment trigger prices do not move in lockstep with variations in the corporate tax rate, as in the case of a linear tax system. We show that the gap can either widen or shrink, depending on the tax policy design and regime. In addition, we find that the agency cost under a progressive tax regime is considerably larger than the agency cost under a regressive tax regime when equityholders have to bear all the investment costs. These results are reversed when managers have the ability to issue additional debt to finance the firm's expansion and transfer part of the investment costs to bondholders.     

Corporate Governance,Tax Avoidance,and Financial Constraints

We examine how corporate governance affects the relationship between corporate tax avoidance and financial constraints. Conditional on having poor governance, tax avoidance is associated with greater financial constraints and a greater likelihood of financial distress. In firms with strong governance, however, we find that tax avoidance does not have a negative impact on financial constraints. Our results suggest that tax avoidance is a less useful source of financing for constrained firms when they are plagued with potential agency problems and opaque information environments. Stronger governance mechanisms can help firms mitigate the negative consequences of tax avoidance.     

Corporate giving and the case of tax avoidance

Prior studies suggest that the association between corporate social responsibility (CSR) and tax avoidance is nuanced. Corporate giving, a CSR strength, is a discretionary activity primarily driven by management values. We propose that corporate giving promotes community-mindedness. Paying a fair share of tax is consistent with this value. We hypothesize that corporate giving and tax avoidance are negatively associated. Our findings support this hypothesis, suggesting that firms that generously contribute to charitable causes are less aggressive in avoiding tax. The association holds when tax avoidance is measured over a multi-year period, is more pronounced in a good economy, and is evident among highly profitable firms, firms subject to low political costs, and domestic firms.     

Tax credit rating and corporate innovation decisions

The tax credit rating mechanism was formally implemented in 2014. As an important tax collection and management innovation, it has attracted the attention of regulatory authorities and scholars. Different from the literature that directly examines corporate tax compliance, we focus on the impact of tax credit rating implementation on corporate research and development (R&D) investment decisions. Using listed companies’ data from 2014 to 2019, we find that companies with higher tax credit ratings invest more in innovation, because the system helps managers identify R&D opportunities, alleviates corporate financing constraints and reduces agency costs. We confirm that tax credit ratings have manifold impacts on corporate information environments and business decisions, with better ratings positively affecting firms’ business decisions. This discovery can inform tax policy reform, encourage corporate innovation and construct social credit systems.     

Do corporate tax cuts increase investments?

This paper studies the effect of corporate taxes on investment. Since firms with a foreign parent have more cross-country profit shifting opportunities than domestically owned firms do, their effective tax rate and, consequently, their tax-induced costs to investment are lower. We therefore expect capital investment responses to a corporate tax cut to be heterogeneous across firms. Using firm-level data on German corporations, we exploit the 2008 tax reform, which substantially cut corporate taxes as an exogenous policy shock and expect domestically owned firms' investments to be more responsive to the reform. We show exactly this in a difference-in-differences setting. We find that the reduction in corporate tax payments led to a one-to-one increase in the real investments of domestic firms. The effect is stronger for domestic firms relying more on internal funds. Correspondingly, labor investment increased more for domestic firms, ensuring a constant mix of input factors. In addition, we show that domestic firms' sales grew faster after the tax cut than the sales of foreign-owned firms. Our results imply that corporate tax changes can increase corporate investment but that domestic firms benefit more than foreign-owned firms from a tax cut through higher investment responses resulting in greater sales growth.     

Does corporate tax avoidance promote managerial empire building?

We examine the association between corporate tax avoidance and empire building using 35,060 firm-year observations from the United States (US) for the period 1991–2015. We build a composite empire building measure by conducting a factor analysis on four popular empire building proxies used in the literature. We find a positive association between this composite measure and the four proxies used to represent the tax avoidance of firms in our sample. As our results suggest, agency problems are inflicted upon firms employing tax avoidance strategies which, in turn, facilitate managerial rent extraction through aggressiveness in growth and the accumulation of assets. Furthermore, the relationship of corporate tax avoidance to managerial empire building is found to be more pronounced in firms with weak governance, poor monitoring mechanisms, greater Chief Executive Officer (CEO) power and weak corporate social responsibility (CSR) performance. We also find that empire building-motivated tax avoidance leads to lower firm valuation. Our results remain insensitive even when employing several robustness tests.     

Investment timing,liquidity, and agency costs of debt

This paper examines the effect of debt and liquidity on corporate investment in a continuous-time framework. We show that stockholder–bondholder agency conflicts cause investment thresholds to be U-shaped in leverage and decreasing in liquidity. In the absence of tax effects, we derive the optimal level of liquid funds that eliminates agency costs by implementing the first-best investment policy for a given capital structure. In a second step we generalize the framework by introducing a tax advantage of debt, and we show that an interior solution for liquidity and capital structure optimally trades off tax benefits and agency costs of debt.     

Financial hedging and corporate investment

Building on the well-documented relationship between corporate financial hedging and firms' borrowing costs, this study examines the impact of utilizing financial derivative instruments on corporate investment. We document that engaging in financial hedging enables firms to pursue more inorganic growth opportunities in the form of M&As. Acquiring firms with financial hedging programs have a lower borrowing cost and are more likely to pay for their deals with cash and use external borrowing. While financial hedging serves as a vehicle for firms to bring their inorganic investment plans to fruition by facilitating their financing, it also leads to inferior investment choices when conflicts of interest among managers and shareholders are more likely to arise. Our study shows for the first time that the financial flexibility emanating from corporate financial hedging can give rise to agency costs by instigating entrenched managers to overinvest.     

Corporate payout policy in dual-class firms

We examine corporate payout policy in dual-class firms. The expropriation hypothesis predicts that dual-class firms pay out less to shareholders because entrenched managers want to maximize the value of assets under control and the associated private benefits. The pre-commitment hypothesis predicts that dual-class firms pay out more to shareholders because firms use corporate payouts as a pre-commitment device to mitigate agency costs. Our results support the pre-commitment hypothesis. Dual-class firms have higher cash dividend payments and total payouts, and they use more regular cash dividends rather than special dividends or repurchases, compared to their propensity-matched single-class firms. Dual-class firms with severe free cash flow-related agency problems and few growth opportunities rely even more on corporate payouts as a pre-commitment mechanism. We also rule out the alternative explanation that dual-class firms pay out more because super-voting shareholders lack the ability to generate home-made dividends by selling shares since super-voting shares are often non-tradable or very illiquid.     

Women on boards of directors and corporate philanthropic disaster response

In this study we conduct firm-level analysis of the impact of women in the boardroom on corporate philanthropic disaster response (CPDR). We propose that CPDR contains agency costs and that female directors are more likely to restrain the associated agency costs of CPDR. We predict a negative relationship between the ratio of women on boards of directors (WoBs) and philanthropic contribution, which is weaker in firms with political connections and stronger in firms with better-developed institutional environments. Data was collected from the philanthropic responses to the Wenchuan earthquake on May 12, 2008 of privately-owned listed Chinese firms. The results support the hypothesized negative relationship, which is found to be weaker in firms with political connections. However, marketization-related factors do not significantly moderate this relationship. These results indicate that CPDR contains agency costs and that female directors do not facilitate the corporate donation process, but rather evaluate the benefits and restrain the associated agency costs.     

The conditional nature of the value of corporate governance

Agency theory suggests that governance matters more among firms with greater potential agency costs. Rational investors are unlikely to value safeguards against unlikely events. Yet, few studies of the relation between governance and firm value control for investor perceptions of the likelihood of agency conflicts. Shleifer and Vishny [Shleifer, A., Vishny, R.W., 1997. A survey of corporate governance. Journal of Finance 52, 737–783] identify investment-related agency conflicts as the more severe type of agency conflicts in the US. We measure the perceived likelihood of this type of agency conflict using free cash flow (Jensen, M.C., 1986. Agency costs of free cash flow, corporate finance, and takeovers. American Economic Review 76, 323–329). We find that firm value is an increasing function of improved governance quality among firms with high free cash flow. In contrast, governance benefits are lower or insignificant among firms with low free cash flow. We show that not controlling for this conditional relation between governance and firm value could lead to erroneous conclusions that governance and firm value are unrelated.     

Are target leverage ratios stable? Investigating the impact of corporate asset restructuring

If firms balance the benefits and costs of leverage, then we might expect corporate asset shocks to trigger a change in corporate target leverage. We investigate the impact of corporate asset restructuring and find that target leverage after restructuring is reduced for downsizing firms and increased for upsizing firms. Changes in target leverage are stabilized by the second year after the restructuring event and are monotonic relative to the degree of restructuring. Decomposition analysis shows that corporate asset restructuring directly and significantly affects target debt ratios. Compared to control firms, downsizing firms adjust claims by repurchasing debt while upsizing firms issue debt securities. As expected, debt repurchases are associated with lower tax liabilities while debt issuance decisions correspond to lower growth proxies and are consistent with a higher adverse selection cost of issuing equity, positive leverage deficit, higher tax liabilities, and lower bankruptcy risk.     

Capital Structure, Agency Problems, and Deposit Insurance in Banking Firms

This paper applies and synthesizes various theories of corporate finance, including capital structure, agency insurance, and regulation, to the case of banking firms and the deposite insurance system. It is argued that a value-maximizing bank would reach its optimal capital structure by minimizing the agency costs of incentive conflicts among stockholders, managers, uninsured depositors, and the deposit insurance agency. Although a regulatory imposed capital requirment may reduce the agency costs inherent in the insurance contact, it cannot produce a universal capital structure that is optimal for all insured banks. The observed capital structure patterns also suggest that banks actively seek an optimal capital structure.     

Adjustment costs of institutional tax changes from the audit pricing perspective: Empirical evidence from the VAT reform

Institutional changes inevitably impose adjustment costs on firms while also generating benefits. However, empirical evidence regarding the adjustment costs of institutional changes is limited, with much of the focus centered on benefits. Using data on China’s A-share listed companies from 2010 to 2018 and the nation’s staggered adoption of the “business tax to value-added tax reform” (hereafter, “VAT reform”) as a natural experiment, we examine the impact of this reform on a particular corporate cost: audit fees. We find audit fees to be 8.11% higher for VAT reform firms than for non-VAT reform firms. This difference does not exist before or after the reform year. That is, it is only observed in the year of VAT reform implementation. This indicates the existence of an adjustment cost specifically related to the VAT reform. Furthermore, we observe larger fee increases among firms audited by Big 4 international audit firms, firms that require more audit work, firms that are more complex, and firms with weak internal controls. From the audit pricing perspective, we provide evidence of the economic consequences of tax reform. The corporate adjustment costs that arise from institutional changes deserve more attention from decision-makers.     

Annual report readability and corporate agency costs

Annual reports are the main sources of information for outside investors’ investment decisions and enable shareholders to supervise the management. Difficulties with the readability of these reports may therefore have serious consequences. Using 19,221 firm-year observations of Chinese A-share listed firms from 2001 to 2015, we investigate the association between annual report readability and corporate agency costs, where readability is proxied by report file length and/or file size. We find that firms with better annual report readability experience lower agency costs, and the negative association between readability and agency costs is more pronounced in firms with higher external audit quality, internal control quality or analyst coverage. These results hold after several robustness checks. The positive effect of annual report readability is stronger in private firms than in state-owned enterprises, and becomes stronger after the implementation of new accounting standards in 2007. Readable annual reports can help in monitoring corporate insiders’ opportunistic behavior and thus reduce agency costs.     

The impact of government ownership on dividend policy in China

We investigate the impact of State ownership on Chinese corporate dividend policy. We find that Chinese firms' dividend payout rates respond fairly quickly to earnings changes, and the average actual payout ratio for Chinese firms falls between the payout ratios for emerging-market and developed firms. These results are consistent with the dividend policies of developing economies in general. We also find that dividend payouts among dividend-paying firms, and the likelihood that a firm will pay a dividend, are increasing in State ownership. Our findings are consistent with the State's need for cash flow as a partial motivation for continued State ownership of a significant portion of the corporate economy, and support the agency and tax clientele explanations for dividend policy.     

Agency and Tax Explanations of Security Issuance Decisions

This paper is an empirical examination of the relative roles of agency and tax considerations in corporate debt versus equity issuance decisions. Unlike earlier work, we conduct our tests on a sample of UK firms since the UK system of taxation does not create an obvious tax advantage to debt and hence affords an opportunity to evaluate the relevance of tax arbitrage considerations. We find that both tax and agency issues are important determinants of security issuance decisions. In addition, we demonstrate that our specification is robust to a variety of alternative explanations which have appeared in the empirical literature.     

Work Ethic, Employment Contracts, and Firm Value

We analyze how the work ethic of managers impacts a firm's employment contracts, riskiness, growth potential, and organizational structure. Flat contracts are optimal for diligent managers because they reduce risk-sharing costs, but they attract egoistic agents who shirk and unskilled agents who add no value. Stable, bureaucratic firms with low growth potential are more likely to gain value from managerial diligence. Firms that hire from a virtuous pool of agents are more conservative in their investments and have a horizontal corporate structure. Our theory also yields several testable implications that distinguish it from standard agency models.     

Tax avoidance in family firms: Evidence from large private firms

Ownership structure plays an important role in firms’ decisions on tax avoidance. Recently, the effect of family ownership on corporate tax avoidance has become an issue of increasing interest among scholars from both the fields of family business research and tax research; however, empirical findings have so far remained ambiguous. Based on a unique sample of 678 large private firms from Germany, we show that for unlisted large firms (i) family firms avoid more tax than non-family firms, (ii) tax avoidance increases with the percentage of family ownership, and (iii) tax avoidance is a function of the number of shareholders. We interpret our results as evidence that benefits from avoiding taxes outweigh the non-tax costs in the case of large private family firms in Germany. Furthermore, as the number of family shareholders increases, family firms satisfy increasing demand for dividends by avoiding taxes.
