A structural model for credit risk with switching processes and synchronous jumps

This paper studies a switching regime version of Merton's structural model for the pricing of default risk. The default event depends on the total value of the firm's asset modeled by a switching Lévy process. The novelty of this approach is to consider that firm's asset jumps synchronously with a change in the regime. After a discussion of dynamics under the risk neutral measure, two models are presented. In the first one, the default happens at bond maturity, when the firm's value falls below a predetermined barrier. In the second version, the firm can enter bankruptcy at multiple predetermined discrete times. The use of a Markov chain to model switches in hidden external factors makes it possible to capture the effects of changes in trends and volatilities exhibited by default probabilities. With synchronous jumps, the firm's asset and state processes are no longer uncorrelated. Finally, some econometric evidence that switching Lévy processes, with synchronous jumps, fit well historical time series is provided.     

Measuring Corpotate Liquidity Risk

This article presents the outline of a framework for evaluating liquidity risk (at the corporate level) with risk measures that are intuitive and economically relevant. In particular, the risk measures are designed explicitly to show the effectiveness of a company's risk management program in helping the firm to (1) avoid financial distress or default and (2) ensure its ability to undertake all strategic investments. For managers attempting to quantify liquidity risks, this paper proposes that the risk measures have two important features: One is to make the liquidity risk estimate depend on some measure of the firm's balance sheet strength, one that reflects the role of the balance sheet as a risk buffer. The second is to provide a useful estimate of the opportunity costs associated with a given liquidity shortage—one that reflects the value of the investment opportunities that liquidity problems could jeopardize. The author illustrates the application of the proposed risk measures with an example of a company evaluating a hedging strategy designed to accompany a substantial increase in its investment budget. Using the risk measures discussed in this paper, the author shows how to assess the effectiveness of a proposed hedge in terms of its expected ability to reduce costly cash shortfalls in scenarios in which the firm's debt capacity is also expected to be depleted.     

Rating or no rating? That is the question: an empirical examination of UK companies

The aim of this paper is to examine the main determinants of the rating likelihood of UK companies. We use a binary probit specification to model the main drivers of a firm's propensity to be rated. Using a sample of 245 non-financial UK companies over the period 1995–2006, representing up to 2872 firm years, the study establishes important differences in the financial profiles of rated and non-rated firms. The results of the rating likelihood models indicate that the decision to obtain a rating is driven by a company's financial risk, solvency, default risk, public debt issuance, R&D, and institutional ownership, thus identifying a wider range of determinants and extending the current literature. The study also finds that the rating decision can be modelled by means of a contemporaneous or predictive specification without any loss of efficiency or classification accuracy. This offers support to the argument that the rating process is fundamentally forward-looking.     

R&D Increases and Long‐Term Performance of Rivals

We examine how a firm's research and development (R&D) increases affect its intra‐industry competitors in the long run. Consistent with the R&D spillover hypothesis, when a firm unexpectedly increases its R&D spending, its intra‐industry competitors experience improvements in operating performance and analyst forecast revisions and earn positive abnormal stock returns in the long run. The industry concentration, which is related to the firm's strategic reaction, is crucial in determining the magnitude of the R&D spillover effect.     

Does freezing a defined benefit pension plan affect firm risk?

This paper examines the impact of a defined benefit (DB) pension plan freeze on the sponsoring firm's risk and risk-taking activities. Using a sample of firms declaring a hard freeze on their DB plans between 2002 and 2007, we observe an increase in total risk (proxied by the standard deviation of EBITDA and asset beta), equity risk (standard deviation of returns), and credit risk following a DB-plan freeze. The increase in credit risk is reflected in a decline in credit ratings and an increase in bond yields for freezing firms. When we examine investment strategies, we observe a shift in investment from capital expenditures before the freeze to more-risky R&D projects after the freeze, and an increase in leverage. These strategies (increased focus on R&D and higher leverage) increase the operating and financial risk the firm faces. Overall, we observe an increase in risk-taking following DB plan freezes, consistent with theories that DB plans act as “inside debt” that aligns managers’ interests with bondholders’.     

Enterprise Risk Management Through Strategic Allocation of Capital

This article presents a conceptual framework for operationalizing strategic enterprise risk management (ERM) in a general firm. We employ a risk‐constrained optimization approach to study the capital allocation decisions under ERM. Given the decision maker's risk appetite, the problem of holistically managing enterprise‐wide hazard, financial, operational, and real project risks is treated by maximizing the expected total return on capital, while trading off risks simultaneously in Value‐at‐Risk type of constraints. This approach explicitly quantifies the concepts of risk appetite and risk prioritization in light of the firm's default and financial distress avoidance reflected in its target credit rating. Our framework also allows the firm to consider a multiperiod planning horizon so that changing business environments can be accounted for. We illustrate the implementation of the framework through a numerical example. As an initial conceptual advancement, our formulation is capable of facilitating more general ERM modeling within a consistent strategic framework, where idiosyncratic variations of firms and different modeling assumptions can be accommodated. Managerial implications are also discussed.     

Corporate capital structure and the characteristics of suppliers and customers

We investigate the link between a firm's leverage and the characteristics of its suppliers and customers. Specifically, we examine whether firms use decreased leverage as a commitment mechanism to induce suppliers/customers to undertake relationship-specific investments. We find that the firm's leverage is negatively related to the R&D intensities of its suppliers and customers. We also find lower debt levels for firms operating in industries in which strategic alliances and joint ventures with firms in supplier and customer industries are more prevalent. Consistent with a bargaining role for debt, we find a positive relation between firm debt level and the degree of concentration in supplier/customer industries.     

Feeling right at home: Hometown CEOs and firm innovation

Extending the theories of social and place identity, we predict that CEO hometown identity has a positive and significant influence on firm innovation. Our empirical evidence, from publicly traded firms in China during 2002–2016, suggests that a firm whose CEO's hometown is in the same province or city as the firm's headquarters tends to invest more in R&D and generate more patent applications. Our results are robust to the firm fixed effects and we use difference-in-differences analysis and instrument variable regressions to mitigate endogeneity concerns. CEOs' hometown identity still has a strong and positive impact on innovation after we control for measures of social capital of CEOs. We identify the mechanisms behind the positive relation between firm innovation and CEO hometown identity: hometown CEOs enjoy more support from the board of directors, they are more willing to take risks, and they are more likely to have long-term visions.     

Product market advertising and corporate bonds

Research shows that by enhancing visibility, advertising improves stock liquidity and returns. Unlike stock holders, bond holders may view advertising skeptically. Without proven effectiveness in improving revenues, large pre-interest advertising expenditures can be seen as eroding a firm's ability to meet its debt service obligations. We find that although greater advertising by a firm improves liquidity of its bonds in the market, it does not lower the firm's cost of debt. However, firms with ineffective advertising experience reduced bond market liquidity and a higher cost of debt. Without a real positive economic impact, advertising has little or no value for bond investors.     

How Do Firm Characteristics Influence the Relationship between R&D and Firm Value?

This paper focuses on how a firm's characteristics affect the market valuation of its research and development (R&D) spending. We derive a valuation model based on the capital market arbitrage condition. Using the generalized method of moments and data from the Eurozone countries to estimate this model yields interesting results. Several firm characteristics (size, firm growth, and market share) positively affect the relationship between firm value and R&D spending, while others (free cash flow, dependence on external finance, labor intensity, and capital intensity) exert a negative effect. Therefore, we conclude that the effectiveness of R&D spending depends on firm characteristics.     

Capital Structure and Debt Priority

We study a defaultable firm's debt priority structure in a simple structural model where the firm issues senior and junior bonds and is subject to both liquidity and solvency risks. Assuming that the absolute priority rule prevails and that liquidation is immediate upon default, we determine the firm's interior optimal priority structure along with its optimal capital structure. We also obtain closed‐form solutions for the market values of the firm's debt and equity. We find that the magnitude of the spread differential between junior and senior bond yields is positively, but not linearly related to the total debt level and the riskiness of assets. Finally, we provide an in‐depth analysis of probabilities of default and the term structure of credit spreads.     

The size,concentration and evolution of corporate R&D spending in U.S. firms from 1976 to 2010: Evidence and implications

The use of research and development (R&D) spending as an empirical proxy for managerial discretion, information asymmetry and growth opportunities, is pervasive in empirical corporate finance research. Underlying this is the implicit assumption that firms choose levels of R&D to maximize value, given firm and industry characteristics. An alternative framework views the level of R&D spending as subject to idiosyncratic behavior as managers myopically manipulate R&D expenditures to meet short-term earnings goals. Using aggregate firm and industry level data, we find evidence consistent with the view that R&D is determined by firm and industry characteristics. Time invariant firm and industry fixed effects explain most of the cross-sectional variation in observed R&D spending, while time-varying factors like size, profitability, or market-to-book explain little of the cross-sectional variation. We find that R&D spending continues to grow faster than advertising and capital expenditures. We also find no evidence of managerial myopia as corporate aggregate R&D expenditures are growing faster than aggregate profitability and the number of firms that undertake R&D has increased over the period from 1976 to 2010.     

Economic policy uncertainty and firm investment decisions: Dilemma or opportunity?

In an environment of economic policy uncertainty (EPU), how to improve efficiency and optimize the scale of firm investment is an important topic worthy of attention. This paper examines the impact of EPU on firms' investment decisions, using Chinese A-share listed companies from 2007 to 2019 as a research sample. The study finds that macro EPU inhibits the increase of firms' investment scale and efficiency while exacerbating the risk of overinvestment or underinvestment. Local EPU enhances a firm's investment scale but simultaneously exacerbates the risk of over- or underinvestment, which in turn inhibits investment efficiency. The mechanism test shows that, first, macro EPU promotes firms' R&D investment but inhibits their green investment. In contrast, local EPU inhibits R&D investment and promotes green investment. Second, macro EPU has a significant negative effect on firms' business performance, while local EPU has a smaller effect. Therefore, in an uncertain environment, the government should actively stabilize the macroeconomic environment, and firms should actively optimize investment structures and improve their risk prevention mechanisms.     

Enterprise Risk Management: Theory and Practice

The Chief Risk Officer of Nationwide Insurance teams up with a distinguished academic to discuss the benefits and challenges associated with the design and implementation of an enterprise risk management program. The authors begin by arguing that a carefully designed ERM program—one in which all material corporate risks are viewed and managed within a single framework—can be a source of long‐run competitive advantage and value through its effects at both a “macro” or company‐wide level and a “micro” or business‐unit level. At the macro level, ERM enables senior management to identify, measure, and limit to acceptable levels the net exposures faced by the firm. By managing such exposures mainly with the idea of cushioning downside outcomes and protecting the firm's credit rating, ERM helps maintain the firm's access to capital and other resources necessary to implement its strategy and business plan. At the micro level, ERM adds value by ensuring that all material risks are “owned,” and risk‐return tradeoffs carefully evaluated, by operating managers and employees throughout the firm. To this end, business unit managers at Nationwide are required to provide information about major risks associated with all new capital projects—information that can then used by senior management to evaluate the marginal impact of the projects on the firm's total risk. And to encourage operating managers to focus on the risk‐return tradeoffs in their own businesses, Nationwide's periodic performance evaluations of its business units attempt to refl ect their contributions to total risk by assigning risk‐adjusted levels of “imputed” capital on which project managers are expected to earn adequate returns. The second, and by far the larger, part of the article provides an extensive guide to the process and major challenges that arise when implementing ERM, along with an account of Nationwide's approach to dealing with them. Among other issues, the authors discuss how a company should assess its risk “appetite,” measure how much risk it is bearing, and decide which risks to retain and which to transfer to others. Consistent with the principle of comparative advantage it uses to guide such decisions, Nationwide attempts to limit “non‐core” exposures, such as interest rate and equity risk, thereby enlarging the firm's capacity to bear the “information‐intensive, insurance‐ specific” risks at the core of its business and competencies.     

What matters more in board independence? Form or substance: Evidence from influential CEO-directors

We exploit heterogeneities among CEO-directors and find that influential CEO-directors (ICDs) provide value through advising and monitoring. To expansively capture their relative influence, we identify CEO-directors who command more pay than the appointing firm's CEO. We find ICDs are more (less) likely to serve on the compensation (audit) committee. ICDs serve on more board seats and benefit more by serving on these seats. ICDs improve the performance of their appointing firm by increasing CEO pay-performance sensitivities and by helping with R&D and M&A activities. Alternatively, uninfluential CEO-directors are largely inconsequential or even detrimental to the appointing firm.     

Valuation of Corporate Innovation and the Pricing of Risk in the Biopharmaceutical Industry: The Case of Gilead

Much of a firm's market value derives from expected future growth value rather than from the value of current operations or assets in place. Pharmaceutical companies are good examples of firms where much market value comes from expectations about drugs still in the development “pipeline.” Using a new osteoporosis drug being developed by Gilead Sciences, Inc., the author combines discounted cash flow methods values and real option models to value it. Alone, discounted cash flow (DCF) calculations are vulnerable to the assumptions of growth, cost of capital, and cash flows. But by integrating the real options approach with the DCF technique, one can value a new product in the highly regulated, risky and research‐intensive Biopharmaceutical industry. This article shows how to value a Biopharmaceutical product, tracked from discovery to market launch in a step‐by‐step manner. Improving over early real option models, this framework explicitly captures competition, speed of innovation, risk, financing need, the size of the market potential in valuing corporate innovation using a firm‐specific measure of risk and the industry‐wide value of growth operating cash flows. This framework shows how the risk of corporate innovation, which is not fully captured by the standard valuation models, is priced into the value of a firm's growth opportunity. The DCF approach permits top‐down estimation of the size of the industry‐wide growth opportunity that competing firms must race to capture, while the contingency‐claims technique allows bottom‐up incorporation of the firm's successful R&D investment and the timing of introduction of the new product to market. It also specifically prices the risk of innovation by modeling its two components: the consumer validation of technology and the expert validation of technology. Overall, it estimates the value contribution per share of a new product for the firm.     

Are scientific indicators of patent quality useful to investors?

Together with the number of patents and the value of R&D expenditures, scientific measures of patent quality give investors a useful basis upon which to judge the economic merit of the firm's inventive and innovative activity. Especially in the case of small cap and relatively low P/E high tech companies, we find a favorable stock-price influence when both the number of patents, the scientific merit of those patents, and R&D spending is high. Patent quality information also appears germane in the case of large cap high-tech companies with relatively high P/E ratios. In short, patent citation information may indeed help investors judge the future profit-earning potential of a firm's scientific discoveries.     

FINANCIAL STRUCTURE AND FINANCIAL STRATEGY

Even if the value of the firm is unaffected by its capital structure, managers may have reasons to choose a particular structure. The prices of the firm's securities reflect the “market's” assessment of the value and riskiness of the firm. Should managers disagree with the market's assessment of the firm's risk or value, they will also disagree about the relative returns on the firm's securities. Concern about shareholder welfare may, therefore, lead them to prefer a specific capital structure. If managers believe the market has underestimated the firm's value, they will prefer debt financing; if the market has overestimated risk, they will prefer equity; and, if managers disagree about both risk and value, they may prefer to finance using both debt and equity.     

Accounting conservatism and corporate social responsibility

In this paper, we examine whether a firm's stakeholder orientation, as manifested by its social responsibility endeavors, matters for its choice of accounting conservatism. We find that the level of conservatism in financial reporting significantly increases with socially responsible activities. This result is robust to several conservatism aspects, including market-based conservatism measure, the aggregate of R&D reserves, advertising reserves, and LIFO reserves, and accrual-based conservatism construct. Moreover, our two-stage regression results validate that conservatism is more pronounced for firms that devote more resources to social responsibility programs. Consistent with stakeholder theory, these findings indicate that CSR-oriented firms are more likely to use accounting conservatism to credibly commit to acting in the interests of stakeholders. As a whole, our results provide a novel implication that the extent of accounting conservatism can be entailed by a firm's efforts to enhance stakeholder relations.     

Intangible Assets and Corporate Signaling

Research and development (R&D) and advertising expenditures often result in patents, technologies and brand names which are difficult to accurately value. Under current generally accepted accounting principles (GAAP) these intangible assets are generally not recognized in the financial statements, but instead are expensed in the period that they occur. Prior studies note that the market-to-book ratios of firms with significant levels of R&D and advertising expenditures suggest that investors, at least partially, value these assets. Researchers and practitioners argue that current GAAP, by not recognizing these intangible assets, reduces the usefulness and relevance of accounting reports.We investigate whether companies with significant levels of intangible assets are more likely to emphasize dividend increases and stock repurchases (which are generally perceived as signaling favorable investment opportunities), instead of traditional accounting disclosures, as a means of overcoming adverse selection. Because these assets are difficult to measure, cash distributions may be viewed as a more credible means of signaling firm value to investors. Using analysts' ratings of firms' accounting disclosures, we find that companies with higher levels of R&D and advertising expenditures are less likely to provide extensive accounting disclosures and instead tend to employ dividend and stock repurchase signals. We obtain these results even after controlling for other firm attributes, such as size, stock returns performance, leverage, liquidity and investors' expectations of growth opportunities. We also find that the market reaction to dividend increase and stock repurchase announcements is greater for firms with higher levels of R&D and advertising expenditures, indicating that these announcements are more informative for such firms.
