自由现金流量创造力与违约风险——来自A股公司的经验证据

本文基于我国A股上市公司数据,研究了企业自由现金流量创造力与违约风险之间的关系。研究发现：(1)企业自由现金流量创造力越强,其违约风险越低。经过一系列稳健性检验后,该结论依旧成立。(2)自由现金流量创造力越强的企业往往有更低的债务规模、更高的资产收益率和更低的股票波动,因而其违约风险更低。(3)自由现金流量创造力与违约风险的负相关关系,主要存在于货币政策紧缩时期以及外部信息环境较差的企业。本文发现意味着,监管部门和投资者应重视上市公司自由现金流量创造力不足所带来的潜在债务违约风险,通过不断提高公司自由现金流量创造力,助力我国宏观经济与微观企业高质量发展。     

“Analysis of Incremental Returns of Canadian Mutual Funds”, J. F. Carrière; C. F. Hill,April 2001

Abstract

The determination and allocation of economic capital is important for pricing, risk management, and related insurer financial decision making. This paper considers the allocation of economic capital to lines of business in insurance. We show how to derive closed-form results for the complete markets, arbitrage-free allocation of the insurer default option value, or insolvency exchange option, to lines of business for an insurer balance sheet. We assume that individual lines of business and the surplus ratio are joint log-normal although the method we adopt allows other assumptions. The allocation of the default option value is required for fair pricing in the multiline insurer. We discuss and illustrate other methods of capital allocation, including Myers-Read, and give numerical examples for the capital allocation of the default option value based on explicit payoffs by line.     

Capital Account Liberalization and Aggregate Productivity: The Role of Firm Capital Allocation

We study the effects of capital account liberalization on firm capital allocation and aggregate productivity in 10 Eastern European countries. Using a large firm‐level data set, we show that capital account liberalization decreases the dispersion in the return to capital across firms, particularly in sectors more dependent on external finance. We provide evidence that capital account liberalization improves capital allocation by allowing financially constrained firms to demand more capital and produce at a more efficient level. Finally, using a model of misallocation we document that capital account liberalization increases aggregate productivity through more efficient capital allocation by 10% to 16%.     

商业银行监管资本套利的均衡分析

监管资本套利,产生于巴塞尔协议资本监管框架的缺陷,是一种利用资本监管制度之间的差异性以及制度内部的不协调性,运用某种手段在不改变实际风险水平的情况下提高资本充足率水平的行为。通过对以下问题的探讨:商业银行监管资本套利所获得的收益在银行与资金需求方之间的配置比例;针对某种资产的监管资本套利,对其他资产供求双方所产生的隐性套利收益的表现形式及其归属程度;由商业银行异质性所导致的监管套利顾客现象;信息不对称情况下,市场对于套利者与非套利者的逆向选择等等,认为银行监管部门应适当引导符合政策意图的套利行为,提高政策引导调控能力。     

The effect of external finance on the equilibrium allocation of capital

We develop an equilibrium model to understand how the efficiency of capital allocation depends on outside investor protection and the external financing needs of firms. We show that when capital allocation is constrained by poor investor protection, an increase in firms' external financing needs may improve allocative efficiency by fostering the reallocation of capital from low to high productivity projects. We also find novel empirical support for this prediction.     

An Economic Approach to Capital Allocation

This article starts with primitive assumptions on preferences and risk. It then derives prices consistent with a social optimum within an insurance company and the consumer‐level capital allocation implied therein. The allocation “adds up” to the total capital of the firm (a result echoing findings in the congestion pricing literature—where optimal tolls exactly cover the rental cost of the highway). The allocation follows each consumer's share of recoveries in states of insurer default, weighted by the severity of the default in terms of welfare impact. However, the article argues that an economic approach technically restricts only the capital allocated to marginal units of coverage: inframarginal units could in principle receive different allocations.     

客观看待个别金融产品的违约事件

本文总结了我国当前金融产品违约的总体情况,分析了个别金融产品违约是实体经济转型和金融体系改革的双重反映,以及金融产品违约个案被过度解读折射出的问题。提出应从引导投资者预期、推动资金业务模式转型,制定资管行业经营行为规范、建立市场化得金融资源配置机制等方面入手,推进金融深化,营造健康有序的投资环境。     

Capital Allocation for Portfolio Credit Risk

Capital allocation rules are derived that maximize leverage while maintaining a target solvency rate for credit portfolios where risk is driven by a single common factor and idiosyncratic risk is fully diversified. Equilibrium conditions ensure that capital allocations depend on interest earnings as well as credits’ probability of default, endogenous loss given default, and asset correlation. Capitalization rates exceed those estimated using Gaussian credit loss models. Results demonstrate that credit risk is undercapitalized by the Basel II AIRB approach in part because of ambiguities regarding the definition of loss given default. An alternative proposed capital rule removes this bias.     

金融资产配置与违约风险:蓄水池效应,还是逐利效应？

本文以2007—2016年中国A股上市公司为研究对象,检验了企业金融资产配置对违约风险的影响。实证研究发现:金融资产持有量越多,企业的违约风险越低,金融资产配置的“蓄水池效应”显著;在货币政策宽松时期,金融资产配置导致的代理冲突显现,宽松的货币政策会抑制金融资产投资对违约风险的降低作用。政府规制也会有一定的公司治理作用,将产业政策纳入讨论发现:对于产业政策支持的行业来说,企业金融资产配置能够降低违约风险,但是宽松的货币政策会刺激管理层的短视投资行为,抑制政府规制的公司治理作用。进一步地,本文提出会计稳健性的提升是企业金融资产配置降低违约风险的重要路径。本文的研究结论丰富了企业金融资产配置动机和违约风险影响因素的讨论,能够为政府部门防范经济运行中的内在风险提供有益借鉴。     

Capital requirements and business cycle regimes: Forward-looking modelling of default probabilities

This paper proposes a forward-looking model for time-varying capital requirements, which finds application within Basel II. The model rests on the relationship between default rates and the business cycle: by positing two regimes, expansion and recession, and by forecasting the associated probabilities, the default probability for each rating class is defined as the expected value of a default rate whose distribution is a mixture of an expansion and a recession distribution. The application to US data over the forecasting period 1971–2002 provides evidence that the model makes it possible to preserve the risk sensitivity of the capital requirement and at the same time to dampen procyclicality.     

Opening the Black Box: Internal Capital Markets and Managerial Power

We analyze the internal capital markets of a multinational conglomerate, using a unique panel data set of planned and actual allocations to business units and a survey of unit CEOs. Following cash windfalls, more powerful managers obtain larger allocations and increase investment substantially more than their less connected peers. We identify cash windfalls as a source of misallocation of capital, as more powerful managers overinvest and their units exhibit lower ex post performance and productivity. These findings contribute to our understanding of frictions in resource allocation within firms and point to an important channel through which power may lead to inefficiencies.     

地理距离、契约设计与企业内部资本市场借贷风险防控——来自中国企业集团内部借贷交易的证据

地理因素对保持距离型市场交易的影响已被大量文献证实,但系统考察地理因素是否以及如何影响企业内部经济活动的研究仍十分匮乏。基于手工搜集整理的企业集团内部委托贷款这一独特数据,我们实证考察了地理距离对企业集团内部借贷契约设计的影响及相关的风险防控问题。实证结果显示,借贷距离越远,针对借款者的契约设计越严苛,不仅贷款者更可能要求借款者提供抵押担保,而且对资金用途施加限制的概率也大幅增加。进一步研究发现,与地理距离阻碍了信息搜集和监督的经济直觉一致,距离对企业内部借贷契约严苛性的推高作用会因为借贷双方之间的信息摩擦问题差异而改变。而且,基于借贷违约信息的检验结果表明,作为应对信息不对称的机制,动态调整契约严苛性这一精巧契约设计有效降低了企业内部贷款违约风险。本文不仅增进了对地理因素影响企业内部资本配置的认识,而且加深了对企业内部借贷契约设计的理解,从而对如何有效防控企业内部资本市场运作风险具有启示意义。     

P2P借款人的定价偏差与被动违约风险——基于“人人贷”数据的分析

本文主要通过行为资产定价理论和"人人贷"2014-2018年的数据,研究网络借贷(P2P)借款人定价偏差的影响因素及其与被动违约风险之间的关系。定价偏差是将P2P借贷利率分解为效率部分和无效率部分,并通过成本随机前沿模型得到。结果表明:借款人定价存在显著偏差且在不同群体间有所差异;借款人的粉饰行为未能起到减小定价偏差的作用,甚至会起到反效果;当借款人的声誉成本高于还款成本时,此时的违约主要表现为被动违约;即使借款人主观还款意愿强烈,但定价偏差越大,借款人剩余收入就越吃紧,还款过程中逾期次数和欠债比例增加的可能性就越大,进而引发被动违约风险。     

Capital income taxation and economic growth in open economies

Can reductions in domestic capital income taxes attract foreign capital and, at the same time, foster economic growth? Using a two-country overlapping generations model with endogenous growth and internationally mobile capital, this paper shows that the effect of domestic capital taxes on the international allocation of capital and on the rate of economic growth do not necessarily go in the same direction. A country can attract capital by reducing its taxes, but this may lower the rate of economic growth depending on the elasticity of saving to the net-of-tax interest rate and on the effect of taxes on domestic factor productivity.     

Modelling Credit Risk for SMEs: Evidence from the U.S. Market

Considering the fundamental role played by small and medium sized enterprises (SMEs) in the economy of many countries and the considerable attention placed on SMEs in the new Basel Capital Accord, we develop a distress prediction model specifically for the SME sector and to analyse its effectiveness compared to a generic corporate model. The behaviour of financial measures for SMEs is analysed and the most significant variables in predicting the entities' credit worthiness are selected in order to construct a default prediction model. Using a logit regression technique on panel data of over 2,000 U.S. firms (with sales less than $65 million) over the period 1994–2002, we develop a one-year default prediction model. This model has an out-of-sample prediction power which is almost 30 per cent higher than a generic corporate model. An associated objective is to observe our model's ability to lower bank capital requirements considering the new Basel Capital Accord's rules for SMEs.     

Do Credit Spreads Reflect Stationary Leverage Ratios?

Most structural models of default preclude the firm from altering its capital structure. In practice, firms adjust outstanding debt levels in response to changes in firm value, thus generating mean-reverting leverage ratios. We propose a structural model of default with stochastic interest rates that captures this mean reversion. Our model generates credit spreads that are larger for low-leverage firms, and less sensitive to changes in firm value, both of which are more consistent with empirical findings than predictions of extant models. Further, the term structure of credit spreads can be upward sloping for speculative-grade debt, consistent with recent empirical findings.     

Financial frictions on capital allocation: A transmission mechanism of TFP fluctuations

This paper provides a theory of financial frictions as a transmission mechanism for news shocks to drive aggregate TFP fluctuations. We show that in an economy calibrated to U.S. data, variations in financial frictions on capital allocation in response to news about future technology can generate aggregate TFP fluctuations and, thus, trigger business cycles before the actual technological change is realized. Using the COMPUSTAT dataset, we find that the relative capital productivity of financially constrained to unconstrained firms is highly countercyclical. Moreover, our VAR analysis shows that news shocks can account for a substantial fraction of the relative capital productivity fluctuations over business cycle frequencies.     

Optimal clearing margin,capital and price limits for futures clearinghouses

We provide a model for a futures clearinghouse to use for setting optimal levels of clearing margin, capital and price limits, which minimizes the costs to clearing firms and simultaneously protects the clearinghouse from default by clearing firms. We show how to estimate the capital requirement, which supports the clearinghouse’s residual default risk that is not covered by the clearing margin. We apply our model to the Winnipeg Commodity Exchange and demonstrate that price limits reduce the sum of optimal clearing margin and capital to a level that is substantially lower than that required in the absence of price limits.     

Firm vertical boundaries,internal capital markets,and firm performance

We investigate how vertical relatedness between business segments of firms affects capital allocation within internal capital markets. Using a battery of tests including exogenous import tariff reductions, we show that investments flow toward segments with better investment opportunities in firms with significant vertical relatedness between segments. This benefit of vertical relatedness is more pronounced in economic environments prone to information problems and in imperfectly competitive industries. Firms with significant inter-segment vertical relatedness also exhibit superior productivity and operating profitability. Overall, we show that superior capital allocation is a channel through which vertical integration impacts real outcomes of firms.     

On the Asset Allocation of a Default Pension Fund

We characterize the optimal default fund in a defined contribution (DC) pension plan. Using detailed data on individuals' holdings inside and outside the pension system, we find substantial heterogeneity within and between passive and active investors in terms of labor income, financial wealth, and stock market participation. We build a life‐cycle consumption‐savings model, with a DC pension account and an opt‐out/default choice, that produces realistic investor heterogeneity. Relative to a common age‐based allocation, implementing the optimal default asset allocation implies a welfare gain of 1.5% during retirement. Much of the gain is attainable with a simple rule of thumb.
