Water as an investment: liquid yet illiquid!

The water industry is in great need of further large investments to address existing severe water shortages worldwide which requires the participation of private sector investors. This industry is heavily infrastructure based and is therefore saddled with fixed assets-in-place or illiquid assets. This exposes the industry to what is termed as ‘illiquidity risk’, and hence, investors in this industry should be compensated for bearing this risk with an appropriate return premium (i.e. extra return). In this study, we provide evidence as to whether illiquidity risk indeed significantly affects returns in this industry. We examine the case of all 76 firms that compose the five major global water indices. After controlling for other factors that impact on returns, our results suggest that asset illiquidity is positively associated with stock returns. Specifically, water firms with a larger proportion of illiquid assets-in-place are observed to have greater stock returns than those with a smaller proportion of illiquid assets. Our results have important implications for the financing of water-related projects particularly those which involve the participation of investors from the private sector.     

FIRE SALES FORENSICS: MEASURING ENDOGENOUS RISK

We propose a tractable framework for quantifying the impact of loss‐triggered fire sales on portfolio risk, in a multi‐asset setting. We derive analytical expressions for the impact of fire sales on the realized volatility and correlations of asset returns in a fire sales scenario and show that our results provide a quantitative explanation for the spikes in volatility and correlations observed during such deleveraging episodes. These results are then used to develop an econometric framework for the forensic analysis of fire sales episodes, using observations of market prices. We give conditions for the identifiability of model parameters from time series of asset prices, propose a statistical test for the presence of fire sales, and an estimator for the magnitude of fire sales in each asset class. Pathwise consistency and large sample properties of the estimator are studied in the high‐frequency asymptotic regime. We illustrate our methodology by applying it to the forensic analysis of two recent deleveraging episodes: the Quant Crash of August 2007 and the Great Deleveraging following the default of Lehman Brothers in Fall 2008.     

New standard regulations regarding allocation to the safety reserve in Sweden

Abstract

This paper describes a statistical investigation of observed loss ratios and run-offs for a number of Swedish insurance companies within different lines of business. The main aim of the investigation was to revise existing upper limits for allocation to the so-called safety reserve, which is an untaxed contingency reserve. The effort was successful in that new rules were established by the Swedish Supervisory Authority in accordance with the results of the investigation. This paper also contains an exposition of the general principles underlying the Swedish safety reserve.     

流动性过剩与股票价格重估

在固定汇率与资本管制框架下,剩余储蓄的持续增加必然导致流动性过剩,对股票市场而言,只有当实体经济持续的剩余储蓄增加引起流动性过剩时,才会推动股票市场估值中枢的剧烈抬升.对近期经济指标的分析表明,股票市场重估将会持续下去,而货币政策紧缩引起的投资下降会进一步扩大剩余储蓄,加快重估的进程.     

基于复合实物期权的公司流动性定价研究

公司流动性是指公司或企业持有的流动性资产,它除了账面价值外,还含有某种潜在价值。对公司流动性价值进行科学的评估,对于投资者、公司管理者等各方都非常重要。采用实物期权理论对公司流动性进行定价。是目前公司金融理论的前沿课题。这方面的研究不但可以打开对公司流动性认知的新视野,还可以促使我们通过了解公司持有的流动性所蕴含的价值,进而对整个公司价值进行真正正确的评估。本文首次揭示了公司流动性的复合实物期权性质,并用复合实物期权二叉树模型进行了公司流动性定价的尝试,为公司财务管理决策提供了一种量化的工具。通过使用复合实物期权模型,我们得到了公司流动性复合期权的价值,这个价值不但大于流动性持有的机会成本和其最初时刻的静态价值,同样也比常用的NPV法算出的项目价值大。多出来的价值就是考虑了流动性复合期权的结果。     

2010-2011年中国宏观经济报告——流动性回收与新规划效应下的中国宏观经济

2010年中国宏观经济步入了"高位回稳"、"经济常态化"、"价格偏高"、"结构良性化"的运行轨道。2011年中国宏观经济一方面延续了2010年经济运行的逻辑,另一方面将出现货币政策的全面转向、外部环境的变异以及"十二五"规划的全面启动等新因素,这决定了2011年中国宏观经济将呈现"复杂但却平稳"的态势。本文利用模型对于相关宏观经济指标进行了预测,并提出了相应的政策建议。     

量化宽松、流动性溢出与新兴市场通货膨胀

全球金融危机愈演愈烈,各国政府使出浑身解数以刺激经济回暖,随着短期利率接近于零,常规货币政策几近失效之时,美、英等发达国家试图通过量化宽松货币政策的实施刺激国内私人部门消费和投资的增长。当国内实体经济无法容纳这部分过剩的流动性时,必然导致流动性溢出,大量国际资本涌入大宗商品市场和新兴市场,催生资产泡沫,给新兴市场国家造成通胀的压力。本文通过新近发展的面板VAR模型分析了量化宽松政策的流动性溢出效应及其对金砖国家物价的影响。     

对银行的流动性风险管理问题的思考

一直以来,流动性风险被称为银行最致命的风险,在银行的经营管理中流动性风险管理更是占有极其重要的地位。可目前银行的流动性风险管理的现状实在令人担忧,因此,如何有效地管理流动性风险就成为当前银行风险管理的核心内容。本文从流动性风险入手,着重阐述了当前银行的流动性风险管理现状,并提出一些应对策略,力图提高银行抵御流动性风险的能力,以供参考。     

浅析我国国际收支

20011年4月10日,海关总署发布的数据显示我国第一季度出现10.2亿的贸易逆差,这是自2004年以来,出现的首个季度逆差.但在在各方密切注视之下,中国6月份的贸易顺差猛增至222.7亿美元.虽然6月进口的增速回落明显快于出口,但不可否认的是近年来贸易顺差一直是我国国际收支的大问题.     

基于双重流动性风险控制的资产组合优化研究

银行危机的实质在于银行资产配置失误而导致的流动性不足,因而在银行资产配置中使得资产保持充分的流动性,对银行的发展至关重要。本文以上一期的负债与资产余额同下一期负债累加作为下一期的总分配资金,使得资产与负债在时间上匹配,通过商业银行法和中央银行对商业银行的监管条例约束,保证银行资产配给的合法性与合规性,控制了银行经营中的流动性风险,保障银行的支付能力。
