Risk Management: Coordinating Corporate Investment and Financing Policies

This paper develops a general framework for analyzing corporate risk management policies. We begin by observing that if external sources of finance are more costly to corporations than internally generated funds, there will typically be a benefit to hedging: hedging adds value to the extent that it helps ensure that a corporation has sufficient internal funds available to take advantage of attractive investment opportunities. We then argue that this simple observation has wide ranging implications for the design of risk management strategies. We delineate how these strategies should depend on such factors as shocks to investment and financing opportunities. We also discuss exchange rate hedging strategies for multinationals, as well as strategies involving “nonlinear” instruments like options.

The Real and Financial Implications of Corporate Hedging

We study the implications of hedging for corporate financing and investment. We do so using an extensive, hand‐collected data set on corporate hedging activities. Hedging can lower the odds of negative realizations, thereby reducing the expected costs of financial distress. In theory, this should ease a firm's access to credit. Using a tax‐based instrumental variable approach, we show that hedgers pay lower interest spreads and are less likely to have capital expenditure restrictions in their loan agreements. These favorable financing terms, in turn, allow hedgers to invest more. Our tests characterize two exact channels—cost of borrowing and investment restrictions—through which hedging affects corporate outcomes. The analysis shows that hedging has a first‐order effect on firm financing and investment, and provides new insights into how hedging affects corporate value. More broadly, our study contributes novel evidence on the real consequences of financial contracting.     

套期保值与金融衍生品风险管理研究

套期保值是企业经营的重要工具,能够锁定企业的经营成本,规避企业的经营风险。但是,如果套期保值运用不当,则会使企业遭受巨额的损失。本文首先对套期保值的原理及其作用进行基本的介绍,然后,结合我国央企巨亏事件,对套期保值巨亏动因进行深入的分析,以揭示套期保值的潜在风险及其认识误区。最后,对我国企业的套期保值风险控制提出若干建议。     

沉淀投资、税收政策竞争与跨国公司发展

如果没有公平的竞争环境,跨国公司的发展会受到限制,可以说建立一个公平竞争的国际环境是跨国公司得以发展的最根本的前提。事实上,公平竞争环境不仅包括产品市场竞争、生产要素市场竞争和金融市场竞争,而且还包括税收政策竞争等经济政策竞争。这些竞争环境都是跨国公司发展的必要国际条件。     

Interest Rate Risk of European Financial Corporations

We investigate the interest rate exposure of large European financial corporations' equity returns. For the period from January 1982 to March 1995 we estimate multifactor index models to examine the sensitivity of equity returns to market index returns and domestic as well as global interest rate movements. In addition, we specify an APT‐model to test whether an exposure to interest rate movements is rewarded in the cross‐section of expected returns. In the four European markets both domestic and global interest rate shifts constitute driving forces of stock returns beyond the influence of the domestic market indices. However, the exposure to interest rate movements does not seem to be rewarded in the same fashion among the markets.     

公司治理与财务治理

我国上市公司治理结构存在着先天性的制度缺陷, 表现在委托代理关系的严重失衡。在完善公司治理的过程中, 应逐步理顺财务报表审计关系和独立董事制度引入中的代理关系, 强化财务治理, 以促使上市公司持续健康的向前发展。     

Hedging and Coordinated Risk Management: Evidence from Thrift Conversions

We provide an explanation for hedging as a means of allocating rather than reducing risk. We argue that when increases in total risk are costly, firms optimally allocate risk by reducing (increasing) exposure to risks that provide zero (positive) economic rents. Our evidence shows that mutual thrifts that convert to stock institutions increase total risk following conversion, consistent with their increased abilities and incentives for risk taking. They achieve this increase by hedging interest-rate risk and increasing credit risk. We provide some evidence that risk-management activities are related to growth capacity and management compensation structure attained at conversion.     

成长性、代理冲突与公司财务政策

本文基于成长性、代理冲突与公司财务政策之系统关联的多维视角分析,着眼于将成长性差异作为一个关键变量时,考察其是否可以成为影响公司代理冲突及其治理与公司财务政策选择的一个重要基础。本文理论分析表明:作为一种制度环境———尤其是作为新兴/转轨经济国家行业与公司的典型特征,成长性差异显著影响公司财务政策;公司治理与公司业绩的关系受制于成长性的高低,成长性通过投资决策、融资选择与股利政策等关键财务政策的中介作用影响公司治理与其价值的相关性;在财务政策中投资决策更具有基础性,融资政策与股利政策都基于提高投资效率而进行选择,将成长性差异影响与公司投资决策相结合、或在公司的投资等关键财务政策的研究和实践之中深入考量成长机会影响,将使得代理冲突及其公司治理更具有针对性和有效性;高成长性可以成为公司治理环境改善的一种有效基础,深入关注(高)成长性的显著"公司治理效应",可以为公司代理冲突及其治理、以及其投融资选择等关键财务政策提供更为清晰的决策信号。     

The Design of Financial Policies in Corporate Spin-offs

We examine differences in financial leverage between parentand spun-off firms that emerge from corporate spin-offs. Ourtests control for past financing choices and the costs of adjustingcapital structure, factors that can obscure cross-sectionalpatterns among firms' target leverage ratios. We find that firmsthat emerge from spin-offs with more financial leverage havea higher cash flow return on assets, lower variability of industryoperating income, and a greater proportion of fixed assets.The positive relation between profitability and the use of financialleverage, in a setting that is free of pecking order effects,is particularly important because it contrasts with existingevidence. Our results indicate that the ability to cover debtpayments and default-related costs are important determinantsof the use of financial leverage, as implied by the trade-offtheory of capital structure. We find no evidence that managerialincentives or governance characteristics affect the differencein leverage ratios in firms that emerge from spin-offs.

Managerial Ownership and Corporate Hedging

Abstract:  Using information on 443 UK non-financial companies, this work provides evidence supporting the hypothesis that managerial risk aversion is an incentive to deviate from the optimal hedging position. Conflicts of interest between shareholders and managers are at the centre of the decision about the firm's risk profile but are not relevant as determinants of the decision to hedge. This is rather associated with factors enhancing the firm's expected value (underinvestment, scale economies, tax savings).     

Degree of Multinationality and Financial Performance: A Study of U.S.-Based Multinational Corporations

This paper examines the marginal benefits that accrue to U.S.-based multinational corporations through increased international investment. Specifically, the study seeks to determine if increased degrees of multinationality produce additional benefits for multinational firms in terms of excess returns and/or reduced risk. The results indicate that during the period studied, the degree of multinationality did not have a significant influence on the risk and return performance of the sample firms. Thus, the study supports the findings of Qian (1996) and Siegel et al. (1995, 1995A) who report that the advantages enjoyed by multinational corporations may be going away.     

Dividend payout determinants for Australian Multinational and Domestic Corporations

I investigate the determinants of dividend payments for Australian Multinational Corporations (MCs) and Domestic Corporations (DCs). Six measures of dividend payout ratios are investigated, and five international factors are employed in addition to traditional factors. I find: MCs pay significantly less regular cash, special cash, total dividends and net dividends relative to DCs; the degree of foreign involvement is important in determining special cash and net dividend payments; MCs are more active than DCs in dividend increasing activities; and MCs are significantly less likely to be a dividend payer relative to DCs due to tax disadvantages coupled with unfavourable foreign risk exposures.     

Financial Leverage,CEO Compensation,and Corporate Hedging: Evidence from Real Estate Investment Trusts

This paper studies the determinants of corporate hedging practices in the REIT industry between 1999 and 2001. We find a positive significant relation between hedging and financial leverage, indicating the financial distress costs motive for using derivatives in the REIT industry. Using estimates of the Black–Scholes sensitivity of CEO’s stock option portfolios to stock return volatility and the sensitivity of CEO’s stock and stock option portfolios to stock price, we find evidence to support managerial risk aversion motive for corporate hedging in the REIT industry. Our results indicate that CEO’s cash compensation and the CEO’s wealth sensitivity to stock return volatility are significant determinants of derivative use in REITs. We also document a significant positive relation between institutional ownership and hedging activity. Further, we find that probability of hedging is related to economies of scale in hedging costs.

Financing Policy, Basis Risk, and Corporate Hedging: Evidence from Oil and Gas Producers

This paper studies the hedging policies of oil and gas producers between 1992 and 1994. My evidence shows that the extent of hedging is related to financing costs. In particular, companies with greater financial leverage manage price risks more extensively.My evidence also shows that the likelihood of hedging is related to economies of scale in hedging costs and to the basis risk associated with hedging instruments. Larger companies and companies whose production is located primarily in regions where prices have a high correlation with the prices on which exchange-traded derivatives are based are more likely to manage risks.     

操作风险管理体制：框架、模式与建构

从理论上讲,一个完整全面的操作风险管理框架至少应该在理论上包括风险管理战略、风险管理流程、基础设施和风险管理环境等四个组成部分。从实践上看,国际上形成了三种比较典型的各具特色的有关操作风险管理体制模式,对于中国各商业银行操作风险管理体制的建构,具有借鉴价值。
