Investment and risk control are becoming increasingly important for financial institutions. Asset allocation provides a fundamental investing principle to manage the risk and return trade‐off in financial markets. This article proposes a general formulation of a first approximation of multiperiod asset allocation modeling for institutions that invest to meet the target payment structures of a long‐term liability. By addressing the shortcomings of both single‐period models and the single‐point forecast of the mean variance approach, this article derives explicit formulae for optimal asset allocations, taking into account possible future realizations in a multiperiod discrete time model.  相似文献

Accounting‐based risk management (ABRM) is a theoretically consistent and practical tool for calculating the cost of capital from underlying financial ratios. In this paper, a sample of ABRM‐generated discount factors is used to generate risk‐adjusted returns, which are compared to CAPM equivalent discount factors. In view of the debates about CAPM's validity, alternative models, the nature and scale of the equity risk premium, and the importance of discount rates in capital budgeting and asset valuation, ABRM's characteristics and resulting discount rates offer a potentially useful alternative. Results suggest that although average discount rates are comparable, their cross‐sectional distributions are dissimilar, so that investors in an average risky firm are overcompensated for systematic risk when using CAPM discount rates, because CAPM discount factors overestimate risk arising from fixed costs in most firms.  相似文献

This paper investigates whether more favorable stock recommendations and higher credit ratings serve as a reputational asset or reputational liability around reputation-damaging events. Analyzing the reputational effects of operational risk announcements incurred by financial institutions, we find that firms with a “Buy” stock recommendation or “Speculative Grade” credit rating are more likely to incur an equity-based reputational damage. In addition, firms with lower credit ratings incur a much more severe debt-based reputational damage. Moreover, credit ratings are more instrumental in mitigating the debt-based reputational damage caused by fraud incidents or incurred in non-banking activities. Furthermore, the misconduct of senior management could demolish the reputation of firms with less heterogeneous stock recommendations. Finally, credit ratings serve as an equity-based reputational asset in the short term but turn into an equity-based reputational liability in the long term. Overall, our analysis reveals that stock recommendations represent a reputational burden and credit ratings act as a reputational shield; however, the persistence and magnitude of such reputational effects are moderated by time and event characteristics.  相似文献

本文以地方融资平台公司发行的城投债为样本,研究来自中央政府的财政转移支付对于地方城投债发行的影响。研究发现,来自中央政府的人均财政专项转移支付每增加1元,会导致地方融资平台公司城投债发行增加人均0.312元,而包括税收返还和一般性转移支付在内的非专项转移支付对城投债的发行并无显著影响。并且,专项转移支付对城投债发行的显著正影响只在中西部省份存在,东部地区并未发现这一机制。本文的进一步研究表明,地方政府债务的借新还旧现象也正在显现,并且变得越来越严重。  相似文献

Exponential affine models (EAMs) are factor models popular in financial asset pricing requiring a dynamic term structure, such as for interest rates and commodity futures. When implementing EAMs it is usual to first specify the model in state-space form (SSF) and then to estimate it using the Kalman filter. To specify the SSF, a structure of the measurement error must be provided which is not specified in the EAM itself. Different specifications of the measurement errors will result in different SSFs, leading to different parameter estimates. In this paper we investigate the influence of the measurement error specification on the parameter estimates. Using market data for both fixed income and commodities we provide evidence that measurement errors are cross-sectionally and serially correlated, which is not consistent with the independent identically distributed (iid) assumptions commonly adopted in the literature. Using simulated data we show that measurement error assumptions affect parameter estimates, especially in the presence of serial correlation. We provide a new specification, the augmented state-space form (ASSF), as a solution to these biases and show that the ASSF gives much better estimates than the basic SSF.  相似文献

本文构建了一个刻画实体企业在流动性金融资产和固定资产之间进行权衡的投资组合选择模型,并创新性地将货币扩张的宏观因素引入微观模型,推演中国实业部门金融化的驱动逻辑。理论模型显示:货币扩张、资本逐利和风险规避本质上是宏观和微观两个不同层面的要素变量,但都卷入实业部门金融化的驱动机制中,然而驱动效应的表现形式要比已有文献的理论模型更加复杂。基于上市公司面板数据总体样本的实证结果表明:货币扩张、资本逐利和风险规避均是企业金融化的关键影响因素,但货币扩张表现为直接抑制和间接促进两种效应。进一步引入宏观风险因素和根据企业所有权性质划分样本的稳健性检验则给出了更为细致的信息:货币因素可能通过宏观风险因素间接作用于企业金融化;所有权性质不同的企业的金融化驱动机制也表现出明显的异质性:国有企业金融化主要受货币因素和风险规避因素影响;民营企业金融资产占比层面的金融化驱动因素是风险规避和资本逐利,而金融渠道获利占比层面的金融化则受到货币因素的显著影响;其他类型企业的金融化主要受货币因素的显著影响。  相似文献

Accounting measurement and disclosure rules have a significant impact on the real decisions that firms make. In this essay, we provide an analytical framework to illustrate how such real effects arise. Using this framework, we examine three specific measurement issues that remain controversial: (1) How does the measurement of investments affect a firm's investment efficiency? (2) How does the measurement and disclosure of a firm's derivative transactions affect a firm's choice of intrinsic risk exposures, risk management strategy, and the incentive to speculate? (3) How could marking‐to‐market the asset portfolios of financial institutions generate procyclical real effects? We draw upon these real effects studies to generate sharper and novel insights that we believe are useful not only for the development of accounting standards, but also for guiding future empirical research.  相似文献

We model the reorganization decision of distressed firms. One of the novel features of our paper is that we examine the asset and liability side restructuring decisions jointly to resolve financial distress. Secondly, we model several institutional features of coping with financial distress such as debtor-in-possession financing, prepackaged bankruptcies, and asset sales. In our model, asset liquidity, indirect costs of financial distress, and the option value of equity are the determinants of the choice between Chapter 11 reorganizations and workouts. The model develops several testable predictions, some of which are novel and others of which are able to explain previously documented empirical results.  相似文献

This article challenges factor models widely used to explain stock returns. For European firms involved in corporate social responsibility (CSR) actions, we find a risk premium associated with extra-financial ratings priced by the market (that is, environmental, social, and governance [ESG] ratings). This premium is calculated as the excess return of low-rated firms compared to high-rated firms. To describe rated firms' returns, we propose a parsimonious two-factor model that includes both the market factor and this premium. Unlike the CAPM, three-, or five-factor models, our model is validated by the Gibbons, Ross and Shanken (1989) test. Our results lead to many managerial implications related to portfolio management, asset pricing, and corporate financial and investing decisions.  相似文献

Recent research provides considerable evidence that correlations between assets change significantly over time and diversification benefits of correlations may vary substantially based on the time-varying measure of correlation used for different asset types. Our study evaluates and compares alternative time-series correlation modeling techniques according to both statistical and economic metrics, focusing specifically on individual asset pairs. We identify the moving correlation structure that best tracks the dynamic conditional correlation estimates using a large set of different financial time series encompassing 467 asset pairs in nine different asset classes. Results from our direct, statistical loss function based, and indirect, portfolio mean-variance based, forecast evaluations provide optimal window-length ranges for 36 asset-class pairs which should help in portfolio construction as well as risk management. Furthermore for robustness tests, we implement the model confidence set approach which, without a benchmark specification, produces a set of models constructed to contain the best models with a given level of confidence among competing forecast evaluations.  相似文献

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。  相似文献

This article reinforces the message of the one immediately preceding by showing that small to medium‐sized firms have even stronger (non‐tax) motives for hedging risks than their large corporate counterparts. Although middle market companies have traditionally been viewed as less sophisticated than their larger corporate counterparts in the risk management arena, the authors suggest that such companies have become increasingly receptive to new hedging strategies using derivative products. When used appropriately, such products allow companies to stabilize their periodic operating cash flow by eliminating specific sources of volatility such as fluctuations in interest rates, exchange rates, and commodity prices. Smaller companies recognize that a single swing in a budgeted cost can have a catastrophic effect on an entire budget, whereas a larger company can more easily absorb such a cost. Moreover, because the principal owners of mid‐sized firms often have a substantial part of their net worth tied up in the business, they are likely to have a far stronger interest than typical outside shareholders in using risk management to reduce the volatility of corporate profits and firm value. Perhaps most important to owners whose firms rely on debt financing, the greater cash flow stability resulting from active risk management significantly reduces the possibility of financial distress or bankruptcy. In this article, three representatives of Bank of America's risk management practice discuss three different exposures faced by middle market companies—those arising from changes in interest rates, foreign exchange rates, and commodity prices—and show how these risks can be managed with derivatives. Besides shielding companies from financial trouble, risk management is also likely to improve their access to the money and capital markets. By protecting the firm's access to capital, risk management increases the odds that the firm will not be forced to pass up good investment opportunities because of capital constraints or fear of getting into financial difficulty.  相似文献

Many models use noise trader risk and corresponding violations of the Law of One Price to explain pricing anomalies, but include a storage technology in perfectly elastic supply or unlimited asset liability. Storage allows aggregate consumption risk to differ from exogenous fundamental risk, but using aggregate consumption as a factor for asset returns can make noise trader risk superfluous. Using (i) limited asset liability and limited storage withdrawals, or (ii) an endogenous locally riskless interest rate eliminates violations of the Law of One Price. Our main results use only budget equations and market clearing, and require virtually no assumptions about behavior.  相似文献

This article focuses on the demutualization process and investigates why certain mutuals undergo this organizational structure change. The primary motivation for conversion is access to capital. By statute, mutual firms are limited in their capital‐raising activities while stock firms can attract funds through a variety of stock and debt offerings. By examining the financial characteristics of firms that demutualize, changes in business practices in the years surrounding conversion can be observed. Determinants of the conversion decision are explored through logistic regression. In the years before demutualization, converting property‐liability mutuals exhibit significantly lower surplus‐to‐asset ratios. This capital constraint eases after demutualization. Converting life‐health mutuals hold a significantly lower proportion of liquid assets; in addition, they have a higher proportion of separate accounts under management. This liquidity constraint and increased focus on a higher managerial discretion activity drive the demutualization decision. For both property‐liability and life‐health converting mutuals, support for the access to capital hypothesis is found.  相似文献

Dynamic financial analysis (DFA) models an insurance company's cash flow in order to forecast assets, liabilities, and ruin probabilities, as well as full balance sheets for different scenarios. In the past years DFA has become an important tool for the analysis of an insurance company's financial situation. In particular, it is a valuable instrument for solvency control, which is now becoming important as regulators encourage insurance companies to determine risk-based capital using internal risk management models. This article considers three aspects: First, we discuss the reasons why DFA is of special importance today. Second, we classify DFA in the context of asset liability management and analyze its fundamental concepts. As a result, we identify several implementation problems that have not yet been adequately considered in the literature, and therefore our third aspect is a discussion of these areas. In particular we consider the generation of random numbers and the modeling of nonlinear dependences in a DFA framework.  相似文献

Deposit Insurance and Forbearance Under Moral Hazard   总被引:1,自引:0,他引:1  
We study the efficacy of forbearance using a real options approach. Our model endogenizes moral hazard embedded in credit risk undertaken by the bank. The bank's interest rate risk is modeled as duration mismatch. Other modeling improvements over previous studies include such features as stochastic interest rates and deposits, continuous interest payments on an ongoing deposit portfolio, and a stochastic forbearance period. We find that the bank does have an incentive to engage in undue risk taking. Even in the presence of moral hazard, however, forbearance can still be a desirable course of action in reducing the FDIC's expected liability. In addition, the capital ratio plays an extremely important role in determining the fair insurance premium. Finally, using the mismatch of asset and deposit durations as the correct measurement of interest rate risk, our model reveals that an optimal asset variance may exist for a particular bank, contrary to what the contingent claims framework would predict. Therefore, we resolve the puzzle that banks in practice do not increase asset risk to take full advantage of the limited liability.  相似文献

Economic conditions have placed increased importance upon rigorous financial analysis. In order to determine which analytical techniques are currently emp loyed by management, a questionnaire was sent to each fm on the May 1980, FORTUNE 500 list. The researchsought to establish a profile of the respondents' organizational structure and to identify the primary procedures used in risk assessment, working capital management, capital budgeting, and operations research modeling. The results do suggest a basic profile of the more active employers of analytical techniques. Relatively sophisticated capital budgeting procedures appear to be accepted across most industries, and many firms support their decision making with a "package" of formal tools.  相似文献

We examine the relationship between economic policy uncertainty (EPU) and stock price crash risk via the corporate investment in Chinese listed firms. Results show that higher EPU is associated with lower crash risk. Firms increase financial asset holdings and reduce overinvestment when EPU rises, leading to lower future crash risk. State-owned enterprises (SOEs) and firms with lower management incentives tend to reduce overinvestment, whereas non-SOEs tend to increase financial asset holdings. Thus, firms tend to be cautious in their investments when EPU is high, which reduces crash risk. Our study provides new insights into the validity of the Lucas critique in China.  相似文献
