随着利率市场化的不断深化,我国商业银行日益面临重大的利率风险。本文简要分析了利率风险的基本态势,同时考察并探究了利率风险管理技术如何适应这类变化。     

金融租赁公司的利率风险及管理对策

金融租赁公司所面临的诸多利率风险中,成熟期错配风险是最为关键的,久期模型是其通用的衡量方法。金融租赁公司的久期缺口分析是利用久期管理利率风险的主要方法,但久期模型运用中也存在着诸如久期对称成本高、利率风险免疫动态性及凸性等问题。金融租赁公司面对利率上升的风险,应采取设立风险管理部门、做好基础资料积累与分析、加强利率走势预测及对金融衍生工具的研究等对策措施。     

The behaviour of producer prices: evidence from French PPI micro data

This paper provides some new empirical findings for how French producers set prices. We used the micro data that composes the producer and business-service price indices from 1994 to 2005. First we address how producer prices are collected. Then we present the main characteristics of how producers change their prices: they are modified infrequently and in small amounts. Also, a behavioural heterogeneity across sectors is observed. Business-service prices change less often than industrial producer prices. The data corroborates both time and state-dependent model predictions. Taylor contracts are not unusual, but a firm’s prices will also react to its economic situation. Nevertheless, the most relevant models, to explain producer price rigidity, are time-dependent.

“The fact that some prices are rigid or sticky, while others are variable, has attracted a good deal of comments from economists in recent years” Tucker (1938)

This study was conducted in the context of the Eurosystem Inflation Persistence Network. Data were processed under the responsibility of INSEE in the context of an agreement between INSEE and the Banque de France (20B-21B-E301/R05019/2005).

The determinants of tendering periods for PPP procurement in the UK: an empirical analysis

The procurement of infrastructure projects via public–private partnerships (PPPs) is rising globally. PPPs are, however, often characterized by lengthy tendering periods, defined as the difference between contract notice and financial close. Tendering periods are important because they account for a significant proportion of overall project delivery time. Slow tendering deters bidders and thus reduces competition for contracts. We source data on 670 PPP projects in the United Kingdom and use a duration analysis model to empirically examine factors that impact tendering period duration. Our results reveal significant sectoral variation with projects in the health and housing sectors taking significantly longer to reach financial close. We also show that, after controlling for other factors, projects with higher capital values and projects that overlap with the timing of general elections are associated with significantly longer tendering periods. We further examine the impact of the competitive dialogue procurement method and find evidence that tendering periods have increased since 2006; the year competitive dialogue was introduced. We do, however, observe a significant reduction in the time between appointment of preferred bidder and financial close post-2006. This suggests that competitive dialogue is effective in reducing the scope for negotiations by preferred bidders holding quasi-monopoly advantages.     

商业银行利率风险计量模型及实证分析--非平移收益曲线条件下的随机免疫策略

传统的久期理论建立在收益曲线平移等严格假设条件上，因而其在实践中的有效性大大降低了。根据Markowitz（1959）等理论可推导出：资产价格的总风险包括收益的方差和全久期向量两部分；假若商业银行采取现金中性（cash neutrality）的资产交易策略，风险计量模型可转换为线性规划问题，从而可以构建基于利率风险最小化模型的随机免疫策略。也就是说，引入随机免疫的理念来替代经典的免疫理论，通过实证分析得出：无现金交易条件下的随机免疫策略能够降低利率风险。     

基于久期缺口的商业银行利率风险免疫策略及实证分析

随着利率市场化的深入，利率风险越来越成为影响商业银行绩效的主要风险，因此，如何对商业银行利率风险进行计量及管理，日益成为国内外学术界高度关注的重要课题。通过建立久期缺口模型，提出了商业银行利率风险免疫策略，并进行实证分析表明：通过确立目标项目，调整资产与负债结构，可以较好地实现商业银行的利率风险免疫。     

地铁工程的进度控制

由于地铁施工建设规模庞大,技术和管理力量难以充分保证,而地铁车站又多位于交通繁杂地段,这给施工增加了很大的难度,也对施工的进度有了相对高的要求,本文结合贵阳市城市轨道工程行政中心车站的施工讲解了施工过程中如何将加快进度与质量统筹兼顾,以保证工程的质量及工期要求。     

盈余管理、审计意见与信贷期限

从债权人信贷风险防范视角出发,基于2009—2020年沪深A股上市公司微观数据,探讨我国转型期经济背景下企业盈余管理对债权人信贷期限的影响。研究发现：企业盈余管理行为的增加会对债权人信贷决策产生干扰,造成信贷期限延长、信贷风险增加,且这种影响在非国有企业中更为显著;引入外部治理机制后发现,审计意见在盈余管理和信贷期限的关系中发挥调节效应,即非标准审计意见会削弱盈余管理对债权人信贷期限决策的干扰;在经济后果方面,通过盈余管理手段获得的长期贷款会导致会计信息质量恶化、代理问题更加突出,进而对企业投资效率、创新水平和企业绩效产生负向影响。研究结论有助于完善债权人保护机制、提高银行信贷风险治理水平和创新综合监管模式,进而为相关部门制定政策建议提供有益指导和证据支持。
