Estimating the Marginal Contribution to Systemic Risk by A CoVaR‐model Based on Copula Functions and Extreme Value Theory

In this paper, we quantify the contribution to systemic risk of a single financial institution by utilizing a analytical framework based on the principles of Extreme Value Theory (EVT) for modelling the marginal distributions and on the properties of copula functions for describing the dependence structure between the financial system and the single financial institution. Among the several systemic risk measures proposed nowadays by academics and estimated by public data, we choose to adopt as systemic risk metric the Conditional Value‐at‐Risk (CoVaR). We select a co‐risk measure like the CoVaR because of its macro‐dimension that allows us to integrate the dependence structure of the single financial institution and of the whole financial system in the systemic risk measurement. While the copula functions have been utilized in some pioneer studies on this area, the EVT principles have not yet been implemented in such a context of systemic risk contribution measurement.     

经济危机下的人力资源管理观察

国际金融危机已历一周年有余,我国企业生存发展的宏观环境不断恶化,很多企业为应对业务萎缩不得不采取各种节约成本措施。其中减少人力资本投资,缩减人力资源管理相关成本成为大多企业的主要选择。降薪、冻薪、降低薪资增长率成为人力资源政策的主流,     

基于虚拟经济视角的资本积累与金融监管

从虚拟经济视角认识当代资本积累、价值化积累已成为一种新的积累制度.这种制度一方面鼓励财富创造,另一方面资本的逐利本性导致投机活动在各类资产之间和各金融市场之间迅速转换,系统性风险增大,实体经济与虚拟经济严重失衡,金融危机频繁爆发.中国资本市场对外开放进入新阶段,从虚拟经济理念出发强调金融监管的整体性、全局性和动态性,有利于防范金融风险,保障国家安全.     

MACROECONOMIC STABILIZATION POLICIES IN THE EMU: SPILLOVERS, ASYMMETRIES AND INSTITUTIONS

This paper studies the institutional design of the coordination of macroeconomic stabilization policies within a monetary union in the framework of linear quadratic differential games. A central role in the analysis plays the partitioned game approach of the endogenous coalition formation literature. The specific policy recommendations in the European Economic and Monetary Union (EMU) context depend on the particular characteristics of the shocks and the economic structure. In the case of a common shock, fiscal coordination or full policy coordination is desirable. When anti‐symmetric shocks are considered, fiscal coordination improves the performance but full policy coordination does not produce further gains in policymakers' welfare.     

职业安全规制问题研究:基于法经济学的视角

控制和减少职业伤害,救济遭受职业伤害的劳动者,维护职业安全,是任何一个民主、法制、健康和谐的社会必须高度重视的社会经济问题,也是政府实施社会性规制的重要领域。我国国民经济高速增长的背后隐藏着巨大的社会成本,包括越来越严重的职业安全问题。各类生产安全事故的频繁发生,职业病发病人数的不断增加,折射出我国劳工状况不容乐观、劳动者权利未能得到有效保护的现实。在建设社会主义和谐社会的大背景下,应该从完善政府社会性规制入手寻求破解之道。

Lab and framed lab versus natural experiments: Evidence from a risky choice experiment

Some recent papers have studied data from TV game shows to examine the behaviour of individuals towards risk. It is generally agreed that data from these shows are useful in detecting individual risk aversion in the field, with both “real life” subjects and incentives. Field experiments also include some interesting reality features that could affect individuals’ behaviour and possibly lead to different findings. This paper aims at investigating lab versus field evidence in risk taking attitudes, especially controlling for framing effects. To assess whether the behaviour of subjects in the field is consistent with that of experimental subjects, we designed an experiment to mimic (with experimental rewards and subjects) the rules of a well-known Italian TV game show, Affari Tuoi, in two different settings: a traditional lab setting, where the game was played individually (109 subjects) (Treatment 1); and a framed lab, in which the experiment was replicated in the Italian public television (RAI) studio where the show was actually recorded, with a smaller sample of undergraduate students (33) and in the presence of an audience (Treatment 2). Our comparison between the two different settings aims at establishing whether the presence of an audience, or of a situation that reproduces the stress that contestants must experience in the TV studio, can affect experimental subjects’ choices. We did not find any significant evidence of framing effects: students behave in a similar way in the two lab settings, responding essentially to incentives. Comparing the risk attitudes shown by experimental subjects in the two lab treatments with those exhibited by the contestants in the field, we found that contestants in the TV show are generally more risk averse than students in the lab.
