金融脆弱性理论综述

金融脆弱性的概念产生于20世纪80年代初期,随着金融自由化、国际化进程的不断深入,金融危机不断爆发并呈现出与以往不同的特征。传统的从外部宏观经济角度来解释金融危机发生的原因越来越缺乏说服力,迫使人们放弃传统的思维方式,从内因的角度即从金融制度自身来解释新形势下金融危机发生的根源。本文主要以传统信贷市场为对象梳理了国外金融脆弱性理论。

Modelling the behaviour of the new issue market

This paper analyses the time series behaviour of the initial public offering (IPO) market using an equilibrium model of demand and supply that incorporates the number of new issues, average underpricing, and general market conditions. Model predictions include the existence of serial correlation in both the number of new issues and the average level of underpricing, as well as interactions between these variables and the impact of general market conditions. The model is tested using 40 years of monthly IPO data. The empirical results are generally consistent with predictions.     

信用风险评级的若干议题

我国的银行业进行信用风险评级,虽然在技术上有一定的“后发优势”,但是绝对不是简单的“直接拿来”。信用风险的内部评级工作需要根植于内部数据,开发适合中国实际情况的评级模型。本文从银行内部评级的角度,对信用风险评级的若干问题进行了讨论,并提出了适当的处理方式。     

关于靖西输气管道建设储气库的设想

随着陕甘宁气田的开发建设和下游用户的落实．陕西省的第一条长输管道靖西线随之兴建．一期输气能力为5亿m^3/a。在此之后又相继建成咸阳至宝鸡、西安至渭南两条输气管线．靖西输气管线输气量逐年上升．自1997年建成通气以来向下游城市累计输送天然气10.3亿m^3。冬季的用气高峰期日输气量已超过原设计能力．2000年达183万m^3,为保证下游高峰用气．于2001年建成靖边压气站并投入使用．

Benefits of Downward Earnings Management and Political Connection: Evidence from Government Subsidy and Market Pricing

This paper examines the role of downward earnings management and political connection on the receipt of government subsidies and market pricing of subsidies. Using subsidies data hand-collected from Chinese listed firms over the period 2004–2014, the results show a significantly positive association between downward earnings management and the receipt of government subsidies. The results also reveal that a firm's political connection is conducive to securing subsidies for poor performers, but not for good performers. Market pricing analyses demonstrate that share markets value subsidies positively in general, but the effect is ameliorated in firms conducting downward earnings management. No discernible difference is found between the market pricing of subsidies received by firms with political connections and those without.     

The impact of privatization on efficiency and profitability

Over the past three decades, China has undergone tremendous economic and social change as a consequence of the transition from a centrally planned to a market economy. This paper examines a key feature of this transition – the privatization of the state‐owned enterprises (SOEs) – through both a theoretical model and empirical analysis. Using newly collected primary data from a variety of sources, we study how privatization of listed SOEs affects employment, wages, profits and other aspects of economic performance at the firm level. Our major finding is that privatization results in substantial downsizing of employment, increased labour productivity and rising profitability.     

Credibilistic risk aversion

In the probabilistic risk aversion approach, risks are presumed as random variables with known probability distributions. However, in some practical cases, for example, due to the absence of historical data, the inherent uncertain characteristic of risks or different subject judgements from the decision-makers, risks may be hard or not appropriate to be estimated with probability distributions. Therefore, the traditional probabilistic risk aversion theory is ineffective. Thus, in order to deal with these cases, we suggest measuring these kinds of risks as fuzzy variables, and accordingly to present an alternative risk aversion approach by employing credibility theory. In the present paper, first, the definition of credibilistic risk premium proposed by Georgescu and Kinnunen [Fuzzy Inf. Eng., 2013, 5, 399–416] is revised by taking the initial wealth into consideration, and then a general method to compute the credibilistic risk premium is provided. Secondly, regarding the risks represented with the commonly used LR fuzzy intervals, a simple calculation formula of the local credibilistic risk premium is put forward. Finally, in a global sense, several equivalent propositions for comparative risk aversion under the credibility measurement are provided. Illustrated examples are presented to show the applicability of the theoretical findings.
