中国企业部门脆弱性评估

本文运用中国上市公司的数据研究了中国企业债务上升所带来的风险。结果显示,虽然平均杠杆水平不高,但高杠杆企业存在肥尾现象,致使这些企业的债务在总体企业债务中占显著份额,尤其是房地产、建筑业及国有企业。房地产及建筑企业通常借贷成本较低,因此尽管其杠杆水平较高,仍能承受利率轻微上升所带来的冲击,然而房地产及建筑业的显著下行会使整个企业部门遭受打击。我们的敏感性分析结果显示,如果房地产行业和建筑业利润下降20%,处于财务危机的企业债务占所有上市公司总债务的比重将会上升至1/4。     

Default Risk in Corporate Yield Spreads

An important research question examined in the credit risk literature focuses on the proportion of corporate yield spreads attributed to default risk. This topic is reexamined in light of the different issues associated with the computation of default probabilities obtained from historical default data. We find that the estimated default risk proportion in corporate yield spreads is sensitive to the ex ante estimated term structure of default probabilities used as inputs. This proportion can become a large fraction of the spread when sensitivity analyses are made with respect to the period over which the probabilities are estimated and the recovery rates.     

Is Default Event Risk Priced in Corporate Bonds?

This article provides an empirical decomposition of the default,liquidity, and tax factors that determine expected corporatebond returns. In particular, the risk premium associated witha default event is estimated. The intensity-based model is estimatedusing bond price data for 104 US firms and historical defaultrates. Significant risk premia on common intensity factors andimportant tax and liquidity effects are found. These componentsgo a long way towards explaining the level of expected corporatebond returns. Adding a positive default event risk premium helpsto explain the remaining error, although this premium cannotbe estimated with high statistical precision.     

Corporate Yield Spreads: Default Risk or Liquidity? New Evidence from the Credit Default Swap Market

We use the information in credit default swaps to obtain direct measures of the size of the default and nondefault components in corporate spreads. We find that the majority of the corporate spread is due to default risk. This result holds for all rating categories and is robust to the definition of the riskless curve. We also find that the nondefault component is time varying and strongly related to measures of bond‐specific illiquidity as well as to macroeconomic measures of bond market liquidity.     

Mortgage Default: Classification Trees Analysis

We apply the powerful, flexible, and computationally efficient nonparametric Classification and Regression Trees (CART) algorithm to analyze real estate mortgage data. CART is particularly appropriate for our data set because of its strengths in dealing with large data sets, high dimensionality, mixed data types, missing data, different relationships between variables in different parts of the measurement space, and outliers. Moreover, CART is intuitive and easy to interpret and implement. We discuss the pros and cons of CART in relation to traditional methods such as linear logistic regression, nonparametric additive logistic regression, discriminant analysis, partial least squares classification, and neural networks, with particular emphasis on real estate. We use CART to produce the first academic study of Israeli mortgage default data. We find that borrowers features, rather than mortgage contract features, are the strongest predictors of default if accepting icbadli borrowers is more costly than rejecting good ones. If the costs are equal, mortgage features are used as well. The higher (lower) the ratio of misclassification costs of bad risks versus good ones, the lower (higher) are the resulting misclassification rates of bad risks and the higher (lower) are the misclassification rates of good ones. This is consistent with real-world rejection of good risks in an attempt to avoid bad ones.

Determinants of Corporate Dividend Policy: A Factorial Analysis

This paper re-examines the dividend policy issue by conducting a simultaneous test of the alternative explanations of corporate payout policy using a two-step procedure that involves factor analysis and multiple regression. Several new proxies for theoretical attributes that have appeared in the literature are introduced, including the role of managerial dimensions in determining dividend policy. Strong support is found for the transaction cost/residual theory of dividends. pecking order argument, and the role of dividends in mitigating agency problems. Strong support is also found for the role of managerial consideration in affecting the firm's payout policy; specifically, firms that maintain stable dividend policies and firms that enjoy financial flexibility pay higher dividends. The results appear to support the tax clientele argument.     

Explaining the Relative Decline of Agriculture: A Supply-Side Analysis for Indonesia

The relative decline of agriculture in growing economies isa central feature of economic development and a major influenceon agricultural policies. The literature on the causes of thisdecline has focused on the relative price effects arising fromdemand factors, especially Engel's law, rather than on supply-sideinfluences, such as changes in relative factor endowments anddifferential rates of technical change. This article developsa simple structural model of the transformation of the Indonesianeconomy, applying an error correction mechanism to capture thedynamics resulting from disequilibria and the costs of adjustment.The decline in agriculture's share of gross domestic productis found to be caused much less by the relative price effectstypically emphasized in the literature than by capital accumulationand rapid technical change in agriculture.     

Liquidity and Pricing of Credit Default Swaps in Japan: Evidence from a Benchmark Index for Corporate Debt Claims

This article is a contribution towards the growing empirical literature on the relationship between liquidity and pricing of credit default swaps (CDSs). To the best of my knowledge, the article becomes the first to show that market liquidity does matter to CDS pricing in Japan, by looking into a sole benchmark index of CDS trading for investment-grade debt claims, or the Markit iTraxx Japan (MiJ). The impact of illiquidity on MiJ premia has declined since the International Swaps and Derivatives Association introduced new trade practices in April 2009. The liquidity of the MiJ has increased since the Japan Securities Clearing Corporation started operating as a central counterpart for the MiJ in July 2011. The price discovery ability of the MiJ has also increased since then.     

A Time-Series Analysis of Corporate Payout Policies

I conduct a time-series analysis of corporate payout policies that accounts for the dynamic nature of these decisions and for the interaction among investment decisions and payout policies. The estimation is done with a VAR model of investments, earnings, total payout, and the split of the total payout between dividends and share repurchases. I control for changes in the legal treatment of share repurchases in 1982 and for changes in the relative taxation of dividends and capital gains. I find that: (i) an increase in the taxation of capital gains relative to dividends shifts the split of total payout away from share repurchase and toward dividends; (ii) corporate investment decisions lead payout policies and not the other way around; (iii) increases in corporate total payout are associated with long-term subsequent increases in earnings; (iv) changes in the composition of corporate payout away from share repurchases and toward dividends are associated with subsequent increases in earnings.     

Corporate Financing: An Artificial Agent-based Analysis

We examine corporate security choice by simulating an economy populated by adaptive agents who learn about the structure of security returns and prices through experience. Through a process of evolutionary selection, each agent gravitates toward strategies that generate the highest payoffs. Despite the fact that markets are perfect and agents maximize value, a financing hierarchy emerges in which straight debt dominates other financing choices. Equity and convertible debt display significant underpricing. In general, the smaller the probability of loss to outside investors, the more likely the firm is to issue the security and the smaller the security's underpricing.     

A Corporate View of Research Needs in Corporate Finance

This paper reports the results of a survey of UK chief financial officers (CFOs) drawn from 72 large, 34 medium and 37 small companies on potentially important research topics in corporate finance. The paper suggests that there are gaps between extant academic research and the CFOs ‘needs for such research. The topics that the 143 CFOs would like to see on the research agenda include: the influence of tax laws on financial decision-making; investor reactions to companies concentrating on short-term gains to the almost total neglect of long-term benefits; effects of changes to the law on pension funds; cash flow planning and forecasting; regulators’ awareness of financial issues; and methods for determining the riskiness of a project. Of least importance to the CFOs are research on the significance of bankruptcy costs, influence of the City on corporate financial operations and impact of seasons on operational decisions. The degree of importance attributed to research topics seems to vary with firm size. In general, the findings of this study are similar to those from a survey of financial managers in the US.     

Assessing Economic and Fiscal Reforms in Lebanon: A Dynamic CGE Analysis with Debt Constraints

Since the early 1990s, Lebanon has undertaken a number of economic reforms, covering international trade and internal fiscal policy issues in particular. Simultaneously, debt has been skyrocketing, partially justified by reconstruction needs after the end of the civil war. Fostering economic growth seems to be the only way out of the debt trap, but reforms intended to stimulate growth may well have adverse short-run effects on public and external deficits. We construct a dynamic open-economy computable general equilibrium (CGE) model with debt constraints in the sense that external debt requires physical capital as collateral. The CGE model allows us to study the effects of a number of important economic policy issues, such as fiscal policy reform, World Trade Organization (WTO) membership, and foreign direct investment, in a multisectoral dynamic setting under the realistic assumption that debt constraints relax when the economy starts growing. Included in the results are reports on scenarios of trade liberalization and political stabilization.

Pricing the Risks of Default: A Note on Madan and Unal

In their well-known article, Madan and Unal (1998) presented one of the first intensity-based credit risk models. In this approach the default intensity is directly linked to the market value of the firm's equity. In order to derive the probability of default Madan and Unal have to solve a partial differential equation (PDE). Here, we show that one of the transformations in the derivation of the solution of this PDE is not correct and analyze the difference between the correct solution of the PDE and the solution based on the incorrect transformation. As a consequence of the transformation error the credit risk of a debtor is systematically underestimated.     

Taxes and Corporate Finance: A Review

This article reviews tax research related to domestic and multinationalcapital structure, payout policy, compensation policy, riskmanagement, and organizational form. For each topic, the theoreticalarguments explaining how taxes can affect corporate decisionmaking and firm value are reviewed, followed by a summary ofthe related empirical evidence and a discussion of unresolvedissues. Tax research generally supports the hypothesis thathigh tax rate firms pursue policies that provide tax benefits.Many issues remain unresolved, however, including understandingwhether tax effects are of first-order importance, why firmsdo not pursue tax benefits more aggressively, and whether corporateactions are affected by investor-level taxes.     

Subprime Transitions: Lingering or Malingering in Default?

When a mortgage borrower becomes seriously delinquent (i.e., defaults), the lender initiates a time consuming and complex recovery process that may or may not result in foreclosure and eventual disposition of the real estate collateral (REO). This research studies this transition process for a unique sample of subprime mortgages that were seriously delinquent on September 30, 2001. Eight months later, possible states for the delinquent loans, in order, are 1)to remain delinquent without deteriorating further, 2) foreclosure, 3) worsen, i.e., become more months delinquent, 4) bankruptcy and 5) cure. The data indicate that, relative to prime loans, when subprime loans become seriously delinquent (90 days or longer) they are about twice as likely to become REO but take about four times longer to get there. It is unusual for a subprime default to be cured suggesting considerable forbearance by subprime lenders. We explore determinants of the transition probabilities and find that the most economically important predictors of transition from default to any other state are the number of payments the borrower has made and the loan to value ratio.     

Expected Default Probabilities in Structural Models: Empirical Evidence

We apply a set of structural models (Black and Cox 1976; Collin-Dufresne and Goldstein 2001; Ericsson and Reneby 1998; Leland and Toft 1996; Longstaff and Schwartz 1995; Merton 1974) to estimate expected default probabilities (EDPs) for a sample of failed and non-failed UK real estate companies. Results are generally consistent with models’ predictions and estimates of EDPs for different models are closely clustered. The results of z-scores and synthetic ratings misclassify 33% of the total sample in contrast to 8% misclassification by structural models. Further analysis of EDPs based on logistic regressions suggests the observed misclassification of the companies by structural models is due to special company management and/or regulatory circumstances rather than limitations of these models.
