杠杆率变动、固定资产投资与研发活动——兼论金融赋能高质量发展

本文通过构建一个包含企业固定资产投资与研发投资的理论模型,分析得出企业杠杆率变动与投资行为的非线性关系。实证结果表明,低杠杆下,杠杆率的增大会使企业增加固定资产和研发投资的规模。对于财务柔性更强、发展前景更好的企业,杠杆率的提升能够增大此类企业的研发投入占比,即企业开展更多能够提升技术水平的研发活动。进一步研究发现,短期杠杆与商业信用杠杆的提升有助于财务柔性较好的企业提高研发投资占比,而对于发展前景不佳的僵尸企业,长期杠杆和银行杠杆的提升反而会使其扩大固定资产投资,加剧产能过剩问题。本文的政策含义在于,要在保持宏观杠杆率基本稳定的前提下,引导金融资源更多投入到创新型经济上,给予优质及前景较好的企业一定杠杆率调整空间和自由度,使其能够更好地利用社会资金,激励其开展研发活动,促进金融更好地服务实体经济,赋能高质量发展。     

Bankruptcy, Warrants, and State-Contingent Changes in the Ownership of Control

We consider the design of securities that govern the distribution of cash flows and control rights for an investment project. An entrepreneur, endowed with managerial talent, contracts with an outside investor for required capital. Optimal contracts stipulate that the ownership of control and the distribution of cash flows are specified on a state contingent basis to manage the distortions that develop from the use of outside financing and so make the best use of the advantage in project management enjoyed by insiders. Our results illustrate that the use of warrants and convertible securities, which transfer control of the firm to outsiders in good states, and bankruptcy, which transfers control to outsiders in bad states, are related features of optimal contracts. Our model also indicates that firms will benefit from direct access to two types of bankruptcy processes resembling Chapter 7 and Chapter 11 (including deviations from absolute priority) of the bankruptcy code. This results differs from observed practices since stockholders cannot waive their rights for protection under Chapter 11. We show that when direct access to Chapter 7 is highly valuable, market participants have found clever ways to obtain it.Journal of Economic LiteratureClassification Numbers: G32 and G33.     

Asymmetric Information,Asset Allocation,and Debt Financing

We analyze a signaling game where firms' financing announcements convey private information about their prospects but a moral hazard problem exists in that managers may suboptimally invest. Consequently, the attempt to address an asymmetric information problem exacerbates moral hazard. The equilibrium recognizes both imperfect information problems. Additionally, the firm must determine how to allocate funds between two technologies differing in cash flow timing and managerial accessibility. We define an above-average firm's comparative advantage as that technology which is most dominant relative to a firm with lesser prospects and show that the resultant equilibria follow the lines of the firm's comparative advantage. Finally, we show that separation may be achieved costlessly, i.e., with no explicit signaling cost.     

Taxes, Financing Decisions, and Firm Value

We use cross-sectional regressions to study how a firm's value is related to dividends and debt. With a good control for profitability, the regressions can measure how the taxation of dividends and debt affects firm value. Simple tax hypotheses say that value is negatively related to dividends and positively related to debt. We find the opposite. We infer that dividends and debt convey information about profitability (expected net cash flows) missed by a wide range of control variables. This information about profitability obscures any tax effects of financing decisions.     

Management compensation and earnings-based covenants as signaling devices in credit markets

A firm seeks to raise capital in credit markets to fund risky operating activities. The firm has private information about the future cash flows from such activities. Firm owners delegate operating decisions to a manager who privately learns further information about the distribution of those cash flows subsequent to contracting, but before taking actions. Those actions include the selection of which operating activities to pursue and how much hidden effort to exert. At issue initially after introducing the problem is the efficient design of the manager's compensation as a device for signaling private information to lenders as well as for inducing operating decisions. Our results provide conditions under which a Bayesian Nash separating equilibrium satisfying the Cho–Kreps intuitive criterion exists. Broadly speaking, these results suggest that contracts that resolve internal adverse selection and moral hazard problems may serve as signaling devices in efficiently resolving information asymmetries with external parties. Next, we show how earnings-based debt covenants and the selection of conservative accounting methods may eliminate signaling costs altogether.     

Empire-builders and shirkers: Investment,firm performance,and managerial incentives

We consider the equilibrium relationships between incentives from compensation, investment, and firm performance. In an optimal contracting model, we show that the relationship between firm performance and managerial incentives, in isolation, is insufficient to identify whether managers have private benefits of investment, as in theories of managerial entrenchment. We estimate the joint relationships between incentives and firm performance and between incentives and investment. We provide new results showing that investment is increasing in incentives. Further, in contrast to previous studies, we find that firm performance is increasing in incentives at all levels of incentives. Taken together, these results are inconsistent with theories of overinvestment based on managers having private benefits of investment. These results are consistent with managers having private costs of investment and, more generally, models of underinvestment.     

TOWARD A MORE COMPLETE MODEL OF OPTIMAL CAPITAL STRUCTURE

Most corporate finance practitioners understand the trade-off involved in making effective use of debt capacity while safeguarding the firm's ability to execute its business strategy without disruption. But quantifying that trade-off to arrive at an optimal level of debt can be a complicated and challenging task. This paper develops a simulation model of capital structure that starts by generating multiple estimates of market rates (LIBOR, currency rates) and corresponding company operating cash flows. To arrive at an optimal capital structure, the model then incorporates the shareholder value effects of alternative financing decisions by directly measuring the costs of financial distress, including the costs of missed investment opportunities and higher working capital requirements.
The model generates both a target credit rating and a lower fallback rating that permits a higher level of debt to maintain investments and dividends when operating cash flows are weak. As the model shows, companies with volatile cash flows and significant investment opportunities can add substantial shareholder value by establishing a fallback credit rating that is one or two notches below the target rating. The model also optimizes the mix of fixed versus floating debt, the maturity structure, and the currency composition. Another distinctive feature of the model is its ability to estimate the expected cost of alternative liability structures that can provide the liquidity insurance necessary to sustain the firm through periods of severe stress. This cost turns out to be quite small relative to the total market capitalization of the average firm.     

Morale hazard

We interpret workers’ confidence in their own skills as their morale, and investigate the implication of worker overconfidence on the firm's optimal wage-setting policies. In our model, wage contracts both provide incentives and affect worker morale, by revealing private information of the firm about worker skills. We provide conditions for the non-differentiation wage policy to be profit-maximizing. In numerical examples, worker overconfidence is a necessary condition for the firm to prefer no wage differentiation, so as to preserve some workers’ morale; the non-differentiation wage policy itself breeds more worker overconfidence; finally, wage compression is more likely when aggregate productivity is low.     

Managerial hedging,equity ownership,and firm value

Suppose risk‐averse managers can hedge the aggregate component of their exposure to firm's cash‐flow risk by trading in financial markets but cannot hedge their firm‐specific exposure. This gives them incentives to pass up firm‐specific projects in favor of standard projects that contain greater aggregate risk. Such forms of moral hazard give rise to excessive aggregate risk in stock markets. In this context, optimal managerial contracts induce a relationship between managerial ownership and (i) aggregate risk in the firm's cash flows, as well as (ii) firm value. We show that this can help explain the shape of the empirically documented relationship between ownership and firm performance.     

Macroeconomic Conditions, Firm Characteristics, and Credit Spreads

We study a structural model that allows us to examine how credit spreads are affected by the interaction of macroeconomic conditions and firm characteristics. Unlike most other structural models, our model explicitly incorporates equilibrium macroeconomic dynamics and models a firm's cash flow as primitive processes. Corporate securities are priced as contingent claims written on cash flows. Default occurs when the firm's cash flow cannot cover the interest payments and the recovery rate is dependent on the economic condition at default. Our model produces the following predictions: (i) credit spread is mostly negatively correlated with interest rate; (ii) credit spread yield curves are upward sloping for low-grade bonds; (iii) firm characteristics have significant effects on credit spreads and these effects also vary with economic conditions. These predictions are consistent with the available empirical evidence and generate implications for further empirical investigation.     

Capital Structure, Information Acquisition and Investment Decisions in an Industry Framework

This paper analyzes the relationship between a firm's capital structure and its information acquisition prior to capital budgeting decisions. It is found that low-growth industries can sustain a large number of levered firms. In these industries, leverage is negatively related to a firm's incentive to acquire information during the capital budgeting process. In contrast, high-growth industries only sustain a small number of levered firms. In these industries, levered firms acquire more information than all-equity financed firms. The model yields empirical predictions regarding the effects of leverage on the expected amount and the volatility of corporate investment. While leverage does not affect firm value, highly levered firms generate a more volatile cash flow than firms with low debt levels.     

Asymmetric cash flow sensitivity of cash holdings

Almeida, Campello, and Weisbach (2004) and Riddick and Whited (2009) offer contrasting conclusions regarding the corporate cash flow sensitivity of cash. We use an augmented empirical model to affirm the conclusion in Riddick and Whited that the cash flow sensitivity of cash is generally negative. In addition, we contend that the cash flow sensitivity of cash is asymmetric to cash flow. The asymmetry may be due to several reasons, including binding project contracts, bad news withholding, and agency costs. Using a sample of manufacturing firms from 1972 to 2006, we document that the cash flow sensitivity of cash is negative when a firm faces a positive cash flow environment, supporting Riddick and Whited (2009), but the cash flow sensitivity of cash is positive when a firm faces negative cash flows. We further divide firms into financially constrained and unconstrained ones and find that the cash flow sensitivity of cash asymmetry continues to hold in both groups. When we use institutional holding as a control for the agency problem, we find that firms with better outside monitoring dissave to capture good investment opportunities. All the results support our hypotheses that firms have different levels of responses to their cash holdings when facing positive and negative cash flows.     

Asset Valuation and Performance Measurement in a Dynamic Agency Setting

This paper examines the choice of asset valuation rules from a managerial control perspective. A manager creates value for a firm through his effort choices. To support its operating activities, the firm also engages in financing activities such as credit sales to its customers. Since such financing activities merely change the pattern of cash flows across periods, an optimal compensation scheme must shield the manager from the risk associated with the financing activities. We show that residual income combined with fair value accounting for receivables eliminates this risk and provides an optimal performance measure. In contrast, compensation schemes based only on realized cash flows can be optimal only under exceptional circumstances. We also consider a setting in which there is sufficiently disaggregated information about periodic cash flows so as to eliminate not only the risk associated with financing activities but also the risk associated with customer defaults. The principal then wants to depart from fair value accounting.     

The effect of government quality on corporate cash holdings

We use China as a laboratory to test the effect of government quality on cash holdings. We build on, and extend, the existing literature on government expropriation and its interaction with firm-level agency problems by proposing a financial constraint mitigation argument. We find that firms hold less cash when local government quality is high, which is not consistent with the state expropriation argument, but supports the financial constraint mitigation argument. A good government lowers the investment sensitivity to cash flows and cash sensitivity to cash flows, decreases cash holdings more significantly in private firms, and improves access to bank and trade credit financing. We also test and find support for Stulz's (2005) model on the interaction between government and firm agency problems.     

Capital structure and signaling game equilibria

In this article we model the financing decisions of a firm asa sequential signaling game. We prove that, when insiders haveperfect information regarding the firm's future case flows,the application of 'refinements' to the set of admissible equilibrialeads to the dominance of debt over equity financing. However,we show that when insiders observe the firm's cash flows imperfectly,there may exist sequential equilibria in which this 'peckingorder' breaks down and some firms strictly prefer equity todebt financing. We also prove that, despite the breakdown ofthe pecking order, the announcement effect of equity financingwill be negative relative to debt financing.     

Information Revelation, Lock-In, and Bank Loan Commitments

This paper considers the extent to which loan commitments mitigate the problems of information monopolies that arise when the firm contracts with a private lender. Loan commitments in conjunction with short-term debt often provide the firm with superior investment incentives by influencing both the states in which bargaining occurs as well as the outcomes from bargaining. Commitment contracts are particularly valuable when there is a high likelihood that information about the firm will be publicly revealed ex post. We also identify circumstances under which the firm foregoes commitment financing, relying on short-term debt instead. Journal of Economic Literature Classification Numbers G21, G32, D82.     

Do corporate insiders circumvent insider trading regulations? The case of stock repurchases

We use calculated values of standardized abnormal insider trading activity to investigate for patterns of unusual insider activity around fixed-price and Dutch auction repurchase announcements. Firms are classified according to whether the repurchase is signaling information about future cash flows, about the distribution of excess free cash flows, or about management's attempts to maintain control in the presence of a takeover. We find below normal levels of sales well before the event and above normal levels of sales after the event. This tendency is strongest for fixed-price offers and for firm's conveying information about future cash flows, and is absent for firms involved in takeovers. No evidence exists of abnormal levels of purchases before or after the event. We interpret the evidence as consistent with insiders successfully circumventing policies and regulations designed to prevent the exploitation of private information by timing the pattern of their security sales.     

Optimal design of securities under asymmetric information

A firm must decide what security to sell to raise external capitalto finance a profitable investment opportunity. There is exante asymmetry of information regarding the probability distributionof cashflow generated by the investment. In this setting, wederive necessary and sufficient conditions for a security tobe optimal (uniquely optimal), that is, for pooling at thissecurity to be an (the unique) equilibrium outcome. Using theseconditions we show that the debt contract is (uniquely) optimalif and only if cash flows are ordered by (strict) conditionalstochastic dominance. Finally, we derive an equivalence relationshipbetween optimal security designs and designs that minimize mispricing.     

Rewarding risk-taking or skill? The case of private equity fund managers

We examine whether typical private equity fund compensation contracts reward excessive risk-taking rather than managerial skill. Our analysis is based on a novel model of investment value, cash flows, and fee dynamics of private equity funds. Given the embedded option-like fee components, our results demonstrate that fund managers indeed have an incentive for excessive risk-taking when only fee income from the current fund is considered. However, when managers also consider potential compensation from follow-on funds, their risk-taking incentives depend on their individual skill levels, and skilled managers will have an incentive to reduce fund risk. We also show that managers must generate substantial abnormal returns in order to compensate investors for the given fee components.     

An Integrated Model of Debt Issuance, Refunding, and Maturity

We integrate previous work in this area and develop a multiperiod model that simultaneously determines bond refunding, bond issuance, maturity structure, cash holdings, and bank borrowing policies. The focus here is on providing the required debt funds in the most cost efficient fashion. A strength of the model is that it allows for time varying interest costs, transaction costs, issuance costs, and refunding costs to be firm specific. The output of the model lays out the optimal financing decisions for each time interval that minimize the total discounted cost of providing the funds that match the requisite funds. By limiting the surplus funds available, the model minimizes the management incentive to over invest and thereby reduces the agency costs. The model has economic implications for the financing decisions and the firm's default risk, growth opportunities, riskiness of cash flows, and firm size. JEL Classification: G30
