INTEREST ON EQUITY CAPITAL AS AN EX POST COST: A REPLY

It is argued by Zafiris that the conceptual framework relevant for decisionmaking is also relevant for performance evaluation. He uses this argument to justify the charging of interest on equity capital in determining income. Implicit opportunity costs are thus included in both observed results and in the standard against which performance is measured, revalued in the former case. This argument, in both its general and particular forms, involves two principle misconceptions: about the significance and purpose of implicit opportunity costs, and about what Buchanan means by "what might have been", which in fact corresponds to Demski's ex post performance measure.     

The Capital Structure Puzzle: Another Look at the Evidence

Since the formulation of the Miller and Modigliani propositions over 60 years ago, financial economists have been debating whether there is such a thing as an optimal capital structure—a proportion of debt to equity that can be expected to maximize long‐run shareholder value. Some finance scholars have followed M&M in arguing that both capital structure and dividend policy are irrelevant in the sense of having no significant, predictable effects on corporate market values. Another school of thought holds that corporate financing choices reflect an attempt by corporate managers to balance the tax shields and disciplinary benefits of more debt against the costs of financial distress. Still another theory says that companies do not have capital structure targets, but instead follow a financial pecking order in which retained earnings are generally preferred to outside financing, and debt is preferred to equity when outside funding is required. In reviewing the evidence that has accumulated since M&M, the authors argue that taxes, bankruptcy and other contracting costs, and information costs all appear to play important roles in corporate financing decisions. While much, if not most, of the evidence is consistent with the idea that companies set target leverage ratios, there is also considerable support for the pecking order theory's contention that managements are willing to deviate widely from their targets for long periods of time. According to the authors, the key to reconciling the different theories—and thus to solving the capital structure puzzle—lies in achieving a better understanding of the relation between corporate financing stocks (that is, total amounts of debt and equity) and flows (which security to issue at a particular time). Even when companies have leverage targets, it can make sense to deviate from those targets depending on the costs associated with moving back toward the target. And as the authors argue in closing, a complete theory of capital structure must take account of these adjustment costs and how they affect expected deviations from the targets.     

Equity Markets, Transactions Costs, and Capital Accumulation: An Illustration

Poorly developed equity markets inhibit the transfer of capitalownership. Moreover, the costs of transacting in equity marketsaffect not just the level of investment, but the kinds of investmentsthat are undertaken. Once equity markets allow the ownershipof capital to be transferred economically, reductions in coststend to favor the use of longer-maturity investments. When thereis a relationship between the maturity of an investment andits productivity, transactions cost reductions are conduciveto observing certain kinds of increases in productive efficiency.This article analyzes savings, investment, and consumption decisionsby using an overlapping generations model with two-period-livedagents. The analysis allows for several technologies for convertingcurrent output into future capital that vary by productivityand maturity, and it makes ownership of capital costly to transfer.A reduction in transactions costs will typically alter the compositionof savings and investment, and have potentially complicatedconsequences for capital accumulation and steady-state output.     

International equity portfolio allocations and transaction costs

In spite of the critical role of transaction cost, there are not many papers that explicitly examine its influence on international equity portfolio allocation decisions. Using bilateral cross-country equity portfolio investment data and three direct measures of transaction costs for 36 countries, we provide evidence that markets where transaction costs are lower attract greater equity portfolio investments. The results imply that future research on international equity portfolio diversification cannot afford to ignore the role of transaction costs, and policy makers, especially in emerging markets, will have to reduce transaction costs to attract higher levels of foreign equity portfolio investments.     

The Capital Structure Puzzle: The Evidence Revisited

Since the formulation of the M&M propositions almost 50 years ago, financial economists have been debating whether there is such a thing as an optimal capital structure—a proportion of debt to equity that maximizes shareholder value. Some finance scholars have followed M&M in arguing that both capital structure and dividend policy are largely "irrelevant" in the sense that they have no significant, predictable effects on corporate market values. Another school of thought holds that corporate financing choices reflect an attempt by corporate managers to balance the tax shields and disciplinary benefits of greater debt against the costs of financial distress. Yet another theory says that companies do not have capital structure targets, but simply follow a financial "pecking order" in which retained earnings are preferred to outside financing, and debt is preferred to equity when outside funding is required.
In reviewing the evidence that has accumulated since M&M, the authors argue that taxes, bankruptcy (and other "contracting") costs, and information costs all appear to play an important role in corporate financing decisions.

According to the authors, the key to reconciling the different theories—and thus to solving the capital structure puzzle—lies in achieving a better understanding of the relation between corporate financing stocks (the levels of debt and equity in relation to the target) and flows (or which security to issue at a particular time).     

Labor cost voluntary disclosures and firm equity values: Is human capital information value-relevant?

This study examines the market value relevance of labor cost voluntary disclosures using a valuation model relating firm market values to book values of equity and to disclosed human capital information, such as labor costs, net pension liabilities (NPLs), and estimated average and marginal labor productivity and efficiency indicators. Results indicate that labor cost disclosing companies command higher equity market values in general, and that labor productivity and efficiency measures appear to be undervalued. Both findings suggest that there might be market opportunities for firms with valuable human capital to differentiate themselves from their industry peers, which might encourage further human capital disclosure in the future. More refined measures of human capital assets and investments are needed to assess firms’ human resource management decisions and performance impacts in the capital markets more adequately.     

Country-specific equity market characteristics and foreign equity portfolio allocation

Do country-specific equity market characteristics explain variations in foreign equity portfolio allocation? We study this question using comprehensive foreign equity portfolio holdings data and different measures of country-specific equity market factors for 36 host countries. Employing panel data econometric estimations, our investigation shows that foreign investors prefer to invest more in larger and highly visible developed markets which are more liquid, exhibit a higher degree of market efficiency and have lower trading costs. The findings imply that by improving the preconditions necessary for well-functioning capital markets, policymakers should be able to attract higher levels of foreign equity portfolio investments.     

Target leverage and the costs of issuing seasoned equity

In this paper, I examine the relation between the direct costs of issuing seasoned equity (SEO gross spreads) and the change in deviation of firms’ leverage ratios from their estimated targets following SEOs. If underwriters have bargaining power vis-a-vis issuing firms in setting SEO fees and if the tradeoff theory of capital structure holds, then SEO fees should be negatively related to the post-SEO change in absolute deviation of firms’ leverage ratios from targets. I find that this relation is indeed negative and economically and statistically significant, especially in cases in which underwriters have relatively high bargaining power, suggesting that one of the important determinants of SEO fees is the change in firms’ absolute deviations from their target leverage as a result of issuing seasoned equity, and that underwriters are able to capture part of the value created by firms moving towards their leverage targets.     

Agency Costs of Overvalued Equity

I define and analyze the agency costs of overvalued equity. They explain the dramatic increase in corporate scandals and value destruction in the last five years; costs that have totaled hundreds of billions of dollars. When a firm's equity becomes substantially overvalued it sets in motion a set of organizational forces that are extremely difficult to manage—forces that almost inevitably lead to destruction of part or all of the core value of the firm. WorldCom, Enron, Nortel, and eToys are only a few examples of what can happen when these forces go unmanaged. Because we currently have no simple solutions to the agency costs of overvalued equity this is a promising area for future research.     

THE CAPITAL STRUCTURE PUZZLE: ANOTHER LOOK AT THE EVIDENCE

Since the formulation of the M & M irrelevance propositions 40 years ago, financial economists have been debating whether there is such a thing as optimal capital structure—a proportion of debt to equity that maximizes current firm value. Some finance scholars have followed M & M by arguing that both capital structure and dividend policy are largely “irrelevant” in the sense that they have no significant, predictable effects on corporate market values. Another school of thought holds that corporate financing choices reflect an attempt by corporate managers to balance the tax shields and disciplinary benefits of greater debt against the increased probability and costs of financial distress. Yet another theory says that companies do not have capital structure targets, but instead follow a financial pecking order in which retained earnings are preferred to outside financing, and debt is preferred to equity when outside funding is required. In reviewing the evidence that has accumulated since M & M, the authors argue that taxes, bankruptcy (and other “contracting”) costs, and information costs (the main factor in the pecking order theory) all appear to play an important role in corporate financing decisions. While much if not most of the evidence is consistent with the argument that companies set target leverage ratios, there is also considerable support for the pecking order theory's contention that firms are willing to deviate widely from their targets for long periods of time. According to the authors, the key to reconciling the different theories—and thus to solving the capital structure puzzle—lies in achieving a better understanding of the relation between corporate financing stocks (leverage ratios) and flows (specific choices between debt and equity). Even if companies have target leverage ratios, there will be an optimal deviation from those targets—one that will depend on the transactions and information costs associated with adjusting back to the target relative to the costs of deviating from the target. As the authors argue in closing, a complete theory of capital structure must take account of these adjustment costs and how they affect expected deviations from the target.     

DIVIDENDS,UNCERTAINTY, AND UNDERWRITING COSTS UNDER ASYMMETRIC INFORMATION

This paper presents a two-period model in which dividends act as a signal of the stability of the firm's future cash flows. It is demonstrated that firms with more stable future cash flows pay a higher dividend. Dividends are a credible signal because the promise of a higher dividend, ceteris paribus, increases the probability that the firm will have to issue equity and pay underwriting costs. Empirically testable implications of the model relating to the cross-sectional determinants of the level of dividends are also discussed.     

Conditional conservatism and the yield spread of corporate bond issues

Building upon recent research which indicates that debt markets rather than equity markets shape financial reporting, this study examines how conditionally conservative financial reporting relates to the yield spread of corporate bond issues. Our findings suggest that the debt contract efficiency/information costs view of conditional conservatism, documented in private debt contracts, does not generalize to public debt contracts. Instead, a debt contract renegotiation costs perspective seems to better capture the dynamics of the public debt markets, with conditionally conservative reporting being associated with higher yield spread of corporate bond issues. Additional subsample test results indicate that the association between conditional conservatism and bond yield spreads is more pronounced in non-investment grade bonds, for bond issuers with more financial distress, and for bonds that are issued before the passage of the Sarbanes–Oxley Act. This study fills a gap in the conservatism literature, which focuses primarily on equity or private bank loan markets with traditional debt contract efficiency/information costs view.     

Tactical Asset Allocation and Stock Issuance in the Korean Stock Market

Stock issuance predicts future stock returns in the Korean market. This creates profitable trading opportunities. Abnormal returns exist in the zero-cost portfolio that short the firms issuing large numbers of shares and longs those issuing small numbers of shares. Their average abnormal return is 12 percent per annum, which is highly significant even after controlling for market, size, value, and momentum factors as well as transaction costs. The authors suggest the possibility of fixed costs in equity market timing. Only the sizable benefit from market timing over fixed costs motivates firms to increase net equity shares.     

INTEREST ON EQUITY CAPITAL AS AN EX POST COST: A COMMENT

This paper attempts to rebut some criticisms advanced by Amey against the conceptual basis of proposals to make an ex post imputation for the cost of equity capital in external fmancial reports. The principle argument is that 'implicit' opportunity costs are relevant not only ex ante, for decision-making, but also ex post, if suitably defined and measured, for performance evaluation. An allowance for the foregone earnings of the equity does, therefore, seem justified. But rather than a standardised imputation of 'interest', the need for comparability across firms suggests firm - or industry - specific allowances which would take account of each firm's gearing and overall riskiness.     

The option to stock volume ratio and future returns

We examine the information content of option and equity volumes when trade direction is unobserved. In a multimarket asymmetric information model, equity short-sale costs result in a negative relation between relative option volume and future firm value. In our empirical tests, firms in the lowest decile of the option to stock volume ratio (O/S) outperform the highest decile by 0.34% per week (19.3% annualized). Our model and empirics both indicate that O/S is a stronger signal when short-sale costs are high or option leverage is low. O/S also predicts future firm-specific earnings news, consistent with O/S reflecting private information.     

Price uncertainty and corporate value

This study examines the sensitivity of equity values of oil producers to changes in the uncertainty of future oil prices. We document that this sensitivity is negatively correlated with a firm's debt ratio and its production costs. These results indicate that companies that are more likely to experience financial distress or underinvestment from low cash flows are adversely affected by increases in the uncertainty of future cash flows. We conclude that corporate risk management can increase shareholder value by reducing the expected costs of financial distress and underinvestment.     

Testing Q theory with financing frictions

We develop a Q theory of investment under financing constraints. The firm invests and saves optimally facing convex costs of external equity, overhang from outstanding debt, and collateral constraints on new borrowing. Overhang and costs of external equity discourage investment. Conversely, firms anticipating collateral constraints experience a side benefit from investing as installed capital relaxes future constraints. Empirical tests support the model. Conditional on average Q, investment is lower for equity issuers and for firms with large debt overhang. The Kaplan and Zingales and the Whited and Wu indices are used as proxies for future collateral constraints. Consistent with the model, both indices enter investment regressions positively.     

Do We Have a Redundant Set of Cost–Efficiency Targets in the NHS?

There has been a long history of hospital trust cost–efficiency targets being used in the National Health Service (NHS), but there is little evidence about whether they are effective in reducing hospital unit costs and reducing the dispersion of unit costs between trusts. In 1997, the new Labour government announced that it would replace the purchaser efficiency index with a new approach to securing cost–efficiency gains from trusts. Since 1999/2000 trust efficiency targets have been based on reference costs. This article presents evidence to suggest that efficiency targets have not been effective and that the new reference cost based system of targets is irrelevant. The efficiency gains that trusts seek to achieve are those that emerge from the purchaser funding formula and the contracting process.     

Equity,efficiency, and discounting : The reasons for discounting intergenerational effects

Confusion between the ethical norm of intergenerational equity and the practical technique of discounting only obscures the basic issues of efficiency and equity. The author distinguishes between the discounting approach and the equity argument, and explains their essentially complementary roles in long-term investment decisions. He argues that the discounting method is an important tool in the achievement of intergenerational equity since it can determine the amount of compensation to be paid to future generations, a sum which by definition will compensate them for the damage our action has caused.     

Tax reform: Analyzing a comprehensive income tax

This paper includes an analysis of the general costs and benefits associated with the introduction of a comprehensive income tax. The introduction of a comprehensive income tax may result in such benefits as simplicity, horizontal equity, and neutrality that may, in turn, be offset by the costs in vertical equity, implementation losses, and efficiency losses. The solution to the question of the desirability of the comprehensive income tax may turn upon the nature of these costs and benefits as well as the philosophy of tax reform that is adopted.
