Corporate hedging versus risk-shifting in financially constrained firms: The time-horizon matters!

The paper presents an intertemporal theory of the optimal risk policy in shareholder-managed firms, which face future financing constraints and act under moral hazard as well as limited liability. Our model provides an integrated framework that overcomes the dilemma of “conflicting motives” of risk-shifting (Jensen and Meckling, 1976) on the one hand and corporate hedging (Smith and Stulz, 1985) on the other hand by considering time-effects. Shareholders face a trade-off between a risk-shifting incentive if the investment horizon is short, and a hedging incentive that becomes dominant if the investment horizon is sufficiently long. Within an infinite-time investment horizon, Jensen and Meckling's risk incentive problem can be fully solved as permanent hedging is optimal except for firms in financial distress, which constantly opt for risk-shifting. We further show that the value of corporate hedging increases if financing constraints become more severe. Our results suggest that life-cycle features play a significant role in the firm's propensity to hedge. They also coincide with existing empirical evidence, which shows that only highly leveraged firms facing financial distress will primarily opt for risk-shifting.     

LEVERAGE,RISK-SHIFTING INCENTIVE,AND STOCK-BASED COMPENSATION

Outstanding risky debt provides risk-shifting incentives for managers fully aligned with stockholders. Earlier research shows that the risk-shifting incentive can be eliminated by using a stock-based compensation design to align managers' and stockholders' interests. I show that stock options as well as compensation designs that align managers' and bondholders' interests eliminate the risk-shifting incentive. Although a stock-based compensation design is not a unique mechanism to eliminate the pure risk-shifting incentive, it is essential where managers of levered firms are known to consume a portion of the investment outlay as perquisites.     

Determinants of corporate borrowing: A behavioral perspective

This article integrates an earnings-based capital structure model into a simple real options framework to analyze the effects of managerial optimism and overconfidence on the interaction between financing and investment decisions. Several empirical implications follow from solving the model. Notably, my analysis reveals that managerial traits can ameliorate bondholder–shareholder conflicts, such as the debt overhang problem. While debt delays investment inefficiently, mildly biased managers can overcome this problem, even though they tend to issue more debt. Similar properties and results are discussed for other real options, such as the asset stripping or risk-shifting problems.     

Why firms issue callable bonds: Hedging investment uncertainty

This paper analyzes a firm's dynamic decisions: i) whether to issue a callable or non-callable bond; ii) when to call the callable bond; and iii) whether to refund it when it is called. We argue that a firm uses a callable bond to reduce the risk-shifting problem in case its investment opportunities become poor. Our empirical findings support this argument. We find that a firm facing poorer future investment opportunities is more likely to issue a callable bond than a firm facing better investment opportunities. In addition, a firm with a higher leverage ratio and higher investment risk is more likely to issue a callable bond. Finally, after a callable bond is issued, a firm with a poor performance and a low investment activity tends to call back a bond without refunding; a firm with the best performance and highest investment activity tends to call back a bond and refund its call; and a firm with mediocre performance and investment activity tends to not call its bonds.     

Risk-Shifting Incentives and Signalling Through Corporate Capital Structure

This paper examines optimal corporate financing arrangements under asymmetric information for different patterns of temporal resolution of uncertainty in the underlying technology. An agency problem, a signalling problem and an agency-signalling problem arise as special cases. The associated informational equilibria and the optimal financing arrangements are characterized and compared. In the agency-signalling equilibrium the private information of corporate insiders at the time of financing is signalled through capital structure choices which deviate optimally from agency-cost minimizing financing arrangements, which in turn induce risk-shifting incentives in the investment policy. In the pure signalling case the equilibrium is characterized by direct contractual precommitments to implement investment policies which are riskier than pareto-optimal levels. Empirical implications for debt covenants and the announcement effect of investment policies and leverage increasing transactions on existing stock and bond prices are explicitly derived.     

Convertible debt and shareholder incentives

Given equity's convex payoff function, shareholders can transfer wealth from bondholders by increasing firm risk. We test the existing hypothesis that convertible debt reduces this classical agency problem of risk-shifting. First, we derive a measure of shareholders' risk incentives induced by convertible debt using a contingent claims framework. We then document that when risk-shifting incentives are high, the propensity to issue convertible (rather than straight) debt increases and the negative stock market reaction following convertible debt issue announcements is amplified. We further highlight that convertible debt is the only type of security that affects business risk durably downwards. Our conclusions support the agency theoretic rationale for convertible debt financing especially for financially distressed firms.     

What determines corporate pension fund risk-taking strategy?

Corporate sponsors of defined benefit pension plans generally assume low investment risk when they have low funding ratios and high default risk, consistent with the risk management hypothesis. However, for financially distressed sponsors and sponsors that freeze, terminate, or convert defined benefit to defined contribution plans, the risk-shifting incentive (moral hazard) dominates. Pension fund risk-taking is also affected by labor unionization and sponsor incentives to maximize tax benefits, restore financial slack, and justify the accounting choices of pension assumptions. Sponsors shift toward an aggressive risk strategy when their pension plans emerge from underfunding, bankruptcy risk is reduced, or marginal tax rate decreases. Overall, we show that corporate sponsors adopt a dynamic risk-taking strategy in their pension fund investments.     

Intertemporal diversification in financial intermediation

This paper examines the incentive problem between a bank and depositors (or deposit insurer): limited liability makes risk-shifting lucrative. We show how intertemporal diversification of lending decisions – i.e. bank’s loan portfolio consists of overlapping long-term loans and is thus gradually renewed – may solve the incentive problem of risk-shifting. A new (or expanding) bank sets a high-equity level and acquires depositors’ confidence. Subsequently, it can allow its equity to depreciate to a permanently lower level. Depositors can control the bank by monitoring equity and realized credit losses ex post; they do not have to monitor bank’s lending choices ex ante. Maturity mismatch – illiquidity of long-term loans and liquidity of deposits – is optimal. The analysis can be extended more generally to the borrower–lender relationship.     

Temporal resolution of uncertainty,disclosure policy,and corporate debt yields

In this paper, we study how risk-shifting incentives and the design of debt covenants are affected by the pattern of temporal resolution of uncertainty (TRU) in the underlying technology of the firm. We show that the extent of risk-shifting as well as the yield demanded on corporate debt are larger the later the resolution of uncertainty (thus providing one explanation for the empirical evidence of Reisz and Perlich (2006)). We allow for contracting based on verifiable information disclosed by the manager. In this context, we characterize optimal covenants restricting investment. The effects of these covenants on the firm's investment policy and corporate bond yields under different disclosure policies and patterns of TRU are studied. Empirical implications are derived and discussed.     

Risk-shifting and investment asymmetry

I show that when shareholders can change not only the variance of the future firm value, but also its asymmetry, they can shift costly risk to bondholders while lowering the firm risk, and more importantly, the equity risk and the probability of bankruptcy. The implication of this result is that risk-shifting behavior can be more beneficial to shareholders than currently perceived in the literature.     

The incentive problem and the design of investment banking contracts

This paper summarizes the first-best contract between an issuer and an investment banker when there is no incentive problem and determines the optimal deviation from that contract when an incentive problem is present. Since the offer price is observable, the issuer can dictate the price he prefers. The issuer, however, is unable to observe the distribution effort, and thus an incentive problem arises. Under reasonable conditions the issuer will give the banker a commission function that is an increasing function of the net proceeds from the issue and involves a bonus when the issue is sold out at the offer price.     

A theory of socialistic internal capital markets

We develop a model of a two-division firm in which the “strong” division has, on average, higher quality investment opportunities than the “weak” division. We show that, in the presence of agency and information problems, optimal effort incentives are less powerful and thus managerial effort is lower in the strong division. This leads the firm to bias its project selection policy against the strong division. The selection bias is more severe when there is a larger spread in the average quality of investment opportunities between the two divisions.     

CEO inside debt holdings and risk-shifting: Evidence from bank payout policies

Bank payouts divert cash to shareholders, while leaving behind riskier and less liquid assets to repay debt holders in the future. Bank payouts, therefore, constitute a type of risk-shifting that benefits equity holders at the expense of debt holders. In this paper, we provide insights on how CEO incentives stemming from inside debt (primarily defined benefit pensions and deferred compensation) impact bank payout policy in a manner that protects debt holder interests. We show that CEOs with higher inside debt relative to inside equity are associated with more conservative bank payout policies. Specifically, CEOs paid with more inside debt are more likely to cut payouts and to cut payouts by a larger amount. Reductions in payouts occur through a decrease in both dividends and repurchases. Our results also hold over a subsample of TARP banks where we expect the link between risk-shifting and payouts to be of particular relevance because it involves wealth transfers from the taxpayer to equity holders. We conclude that inside debt can help in addressing risk-shifting concerns by aligning the interests of CEOs with those of creditors, regulators, and in the case of TARP banks, the taxpayer.     

Implicit Employment Contracts: The Limits of Management Reputation for Promoting Firm Productivity

Implicit employment contracts are a common way to motivate firm productivity but also require that employees trust management to be fair when allocating postproduction firm resources between employees and owners. We use an experiment to study the problem of motivating firm productivity, which depends on levels of owner investment and employee productive effort, when managers have an incentive to favor the owner's interests over those of the employee. Drawing on research in psychology and behavioral economics, we argue that reputation concerns can more effectively promote firm productivity when manager compensation is relatively insensitive to how much the owner is allocated after production occurs. Consistent with our predictions, we find that reputation concerns lead to greater firm productivity and higher payoffs for all firm members, but only when manager pay is relatively insensitive to the owner's ex post allocation. In addition to offering testable empirical implications, our theory and results are important because they can help explain why executive compensation is, in practice, surprisingly insensitive to owner returns.     

Bank dividends,risk, and regulatory regimes

This paper investigates the relation between bank dividends and bank risk over the period 1984–2011, and assesses the existence of risk-taking and risk-shifting in the US commercial banking sector subject to regulatory regime changes. The introduction of PCA in 1992 and TARP in 2008 constitute significant regulatory regime changes, and provide the necessary framework to explore whether regime-dependent risk-shifting or risk-taking is present. We find strong evidence of risk-shifting and risk-taking over the post-PCA regime spanning the period 1992–2008. We interpret this evidence as indication of ineffectiveness of PCA in controlling risk-taking and risk-shifting. The finding of risk-taking just prior to the recent financial crisis suggests that risk-taking may be a factor contributing to this crisis. As risk-taking and risk-shifting are important aspects of bank behavior (Basel Committee on Banking Supervision, 2009), these results are of interest to bank regulators and important to Basel III.     

An elusive panacea? The impact of the regulatory valuation regime on insurers' investment behaviour

This paper develops a framework to examine how the interactions between the valuation regime and solvency requirements influence investment behaviour of long-term investors with stable liabilities, such as life insurers. The results contribute to the debate over market-based valuation regimes, and shed light on new hybrid regimes explored in policy circles. We show that solvency requirements based on fair value regime can induce procyclical asset sales, but those based on historical cost valuation encourage insurers to engage in risk-shifting to the detriment of policyholders. A hybrid valuation regime, intended to address these unfavourable outcomes, does not strictly dominate the other two regimes on its own. However, market-based regimes can be made effective, if regulators calibrate their responses to solvency breaches using supervisory information about insurers' asset quality.     

Moral Hazard and Adverse Selection: The Question of Financial Structure

This paper looks at the moral hazard and adverse selection problems confronting an entrepreneur offering securities to an uninformed, but competitive financial market. The adverse selection aspect of the problem is generated by the unobservable entrepreneur's ability to transform effort into value. Moral hazard arises because the investment decision is made subsequent to financing. We consider the joint use of both debt and equity, and characterize the equilibrium relation between capital structure and unobservable attributes. It is shown that: (1) investment and financing are not separable; (2) there is an underinvestment problem for “better” firms; and (3) simultaneous use of both debt and equity can resolve this difficulty. We also establish a connection between expected terminal firm value and debt-promised payment level and between share retention and standard deviation.     

Agency cost of debt overhang with optimal investment timing and size

The concept of debt overhang (that is, an equity‐maximizing levered firm will under‐invest relative to a firm‐value‐maximizing firm) is well established in the literature. A number of papers have demonstrated it as delayed investment (when investment size is specified) or smaller investment (when investment time is specified). However, there is no work on the underinvestment effect when the firm chooses both size and timing of investment, as it usually does in real life. This is what our paper focuses on. When the firm has the flexibility to choose both size and time, the effect is complicated by the fact that delayed investment results in larger investment, which suggests that the underinvestment problem might be mitigated. We find, however, that the effect depends on how underinvestment is measured. When measured by the expected present value of investment, flexibility can mitigate or exacerbate the underinvestment problem, depending on the cost of installing capacity. But when measured by the agency cost, flexibility always exacerbates the underinvestment problem. It is shown numerically that, at the optimal leverage ratio, the agency cost with plausible parameter values can be economically significant. Thus, with the flexibility of choosing both time and size of investment, the debt overhang problem can be of significant practical relevance in corporate investment decisions.     

Regulating securities analysts

We examine the effects of regulations designed to address the potential conflict of interest that arises when sell-side analyst research is not independent of investment banking. We focus on two types of regulation: (1) internal barriers between equity research and investment banking that restrict communication; and (2) disclosure requirements relating to analyst compensation. We find that information barriers can increase research effort and improve report quality by limiting an investment bank's ability to distort its analyst's incentives. However, this type of regulation can also reduce information production and lower the quality of reports if an investment bank benefits directly from research activity. Disclosure requirements, on the other hand, unambiguously lead to more informative prices and a higher report quality relative to either information barriers or no regulation.
