商业银行利率风险控制策略分析

利率风险控制是利率风险管理的重要环节,也是识别、衡量利率风险工作的归结。按照是否涉及到资产负债表表内的项目,可将利率风险控制分为资产负债表内控制和资产负债表外控制。本文主要对资产负债表外控制策略进行分析,希望能为有效控制商业银行利率风险提供借鉴作用。     

政府投资项目代建制的财政和财务管理工作探讨

代建制作为一种新的建设模式,克服了“投、建、管、用”四位一体的政府投资工程管理模式所带来的非专业化、低效率、低质量等弊端,通过专业化、集中化和市场化的管理,实现投资控制,保证质量和工期。但代建制是有相应的配套制度作保障的,如果制度不配套,依然会存在风险。在新的政府协调干预机制下———建筑工务局的成立,探讨如何搞好代建制的财政财务管理工作。     

Perceptions of postretirement benefit obligations by bond rating analysts

This research examines the measurement and impounding of alternative measures of a corporation's other postretirement benefits obligation (OPEBs) by an important segment of the capital markets. The Kaplan and Urwitz (1979) model is used as a benchmark from which to assess the importance of an added OPEB variable in the bond rating process. Using the corporate bond rating as the dependent variable, multiple measures of the OPEB obligation are inserted individually as an added independent variable into an N-chotomous probit model. The results for 1987 and 1988 indicate that measures calculated from publicly available information produce highly significant results. The developed postretirement liability measures are found to provide relevant and material information regarding the risk level of a firm's bonds as represented by its bond rating. This insight concerning the additional risk represented by a firm's postretirement benefits is beyond that supplied by the firm's pension information. This suggests that the additional investor default risk attributed to a firm's OPEB can be reasonably proxied by data found in the company's annual report footnote disclosures.     

Sovereign risk assessment and agency credit ratings

Sovereign ratings are gaining importance as more governments with greater default risk borrow in international bond markets. However, while the ratings have proved useful to governments seeking market access, the difficulty of assessing sovereign risk has led to agency disagreements and public controversy over specific rating assignments. Recognising this difficulty, the financial markets have shown some scepticism toward sovereign ratings when pricing issues.     

Large portfolio losses

This paper provide a large-deviations approximation of the tail distribution of total financial losses on a portfolio consisting of many positions. Applications include the total default losses on a bank portfolio, or the total claims against an insurer. The results may be useful in allocating exposure limits, and in allocating risk capital across different lines of business. Assuming that, for a given total loss, the distress caused by the loss is larger if the loss occurs within a smaller time period, we provide a large-deviations estimate of the likelihood that there will exist a sub-period of the future planning period during which a total loss of the critical severity occurs. Under conditions, this calculation is reduced to the calculation of the likelihood of the same sized loss over an initial time interval whose length is a property of the portfolio and the critical loss level.Received: March 2003Mathematics Subject Classification: 60F10, 91B28, 91B28JEL Classification: G21, G22, G33Amir Dembo is with the Department of Statistics, Stanford University.

Liquidity Pools, Risk Sharing, and Financial Contagion

This paper reevaluates the Allen–Gale (2000) analysis of interbank deposits to explain financial contagion. This paper modifies the pecking order of asset liquidation developed in Allen–Gale, which is essential in fragility analysis. Furthermore, we also provide a claim structure called liquidity pool that can both achieve risk sharing and prevent financial contagion across regions when asymmetric information about bank assets is absent. This model can partly explain why bank panics reduced substantially after the founding of the Fed and the role of IMF in regional financial crises.     

Efficient rank tests for semiparametric competing risk models

We consider a semiparametric competing risk model given by k independent survival times. The paper offers an asymptotic treatment of tests for the semiparametric null hypothesis of equality of the underlying risks. It turns out that modified rank tests are asymptotically efficient for certain semiparametric submodels, where the baseline hazard is a nuisance parameter. In addition, the asymptotic relative efficiency of the present tests is derived. A comparison of asymptotic power functions can then be used to classify various tests proposed earlier in the literature. For instance a chi-square type test is efficient for proportional hazards. Data driven tests of likelihood ratio type are proposed for cones of alternatives. We will consider certain stochastically increasing alternatives as a special example. The paper shows how the concept of local asymptotic normality of Le Cam works for hazard oriented models.     

Left-side Relatively Weak Increases in Risk and Their Comparative Statics

This paper proposes a new concept, a left-side relatively weak increase in risk (L-RWIR) order, that extends the definition of a relatively weak increase in risk (RWIR) order. We show that, for the class of linear payoffs, one can obtain an appealing comparative statics result for L-RWIR shifts imposing additional restrictions on risk preferences of a risk-averse decision maker.JEL classification: D81.revised version received October 10, 2003Acknowledgements The authors would like to thank an anonymous referee for insightful comments and useful suggestions.     

Precautionary Demand for Education, Inequality, and Technological Progress

This paper offers an explanation for the evolution of wage inequality within and between industries and education groups over the past several decades. The model is based on the disproportionate depreciation of technology-specific skills versus general skills due to technological progress, which occurs randomly across sectors. Consistent with empirical evidence, the model predicts that increasing randomness is the primary source of inequality growth within uneducated workers, whereas inequality growth within educated workers is determined more by changes in the composition and return to ability. Increasing randomness generates a precautionary demand for education, which we show empirically to be significant.     

Recovering Risky Technologies Using the Almost Ideal Demand System: An Application to U.S. Banking

We present and estimate a model that shifts the focus of modeling production from the traditional assumptions of profit maximization and cost minimization to a more general assumption of managerial utility maximization that can incorporate risk incentives into the analysis of production and recover value-maximizing technologies. We implement the model using the almost ideal demand system. In addition, we use the model to measure efficiency in a more general way that can incorporate a concern for the market value of firms assets and equity and identify value-maximizing firms. This shift in focus bridges the gap between the risk incentives literature in banking that ignores the microeconomics of production and the production literature that ignores the relationship between production decisions and risk. Our estimation of the model for a sample of U.S. commercial banks illustrates that results obtained from our generalized model can differ significantly from those obtained from the standard profit-maximization model, which ignores risk.
