Modelling return and conditional volatility exposures in global stock markets

This article empirically investigates the exposure of country-level conditional stock return volatilities to conditional global stock return volatility. It provides evidence that conditional stock market return volatilities have a contemporaneous association with global return volatilities. While all the countries included in the study exhibited a significant and positive relationship to global volatility, emerging market volatility exposures were considerably higher than developed market exposures.

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.     

知识操纵行为意向影响因素研究

知识（尤其是隐性知识）是员工生存和发展的关键资源，知识权利的不完全性决定了知识交换中不可避免地存在欺骗、偷盗、投机等失范行为。在协同创新过程中，知识型员工既相互合作又彼此竞争。除采取知识共享和知识隐藏两种策略外，员工通常会选择折中的、柔性知识操纵策略管理个体知识。由此，界定知识操纵内涵，剖析其自利性、欺骗性、不确定性和隐蔽性4个特点。在此基础上，选择扎根理论方法，通过对68名知识型员工访谈数据进行编码，构建由本体、主体、客体、载体、动机、环境、契合7个主范畴组成的知识操纵影响因素概念模型。最后，围绕知识操纵治理，提出优化创新任务属性、发挥知识操纵对象能动作用、选择高效知识管理载体、培养员工利他特质、营造协同创新环境、提高员工契合度等启示。     

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.     

Comparative persistence and adherence with newer anti-hyperglycemic agents to treat patients with type 2 diabetes in the United States

Objectives: Non-adherence and non-persistence to anti-hyperglycemic agents are associated with worse clinical and economic outcomes in patients with type 2 diabetes. This study evaluated treatment persistence and adherence across newer anti-hyperglycemic agents (canagliflozin, dapagliflozin, sitagliptin, saxagliptin, linagliptin, liraglutide, or exenatide).

Methods: This retrospective cohort study of Truven Health Analytics Marketscan databases included adult patients with type 2 diabetes whose first pharmacy claim for a newer anti-hyperglycemic agent was between February 1, 2014 and July 31, 2014. Treatment persistence and adherence were assessed for 12 months after the first claim (post-index). Persistence was defined as no gap ≥90 days between the end of one pharmacy claim and the start of the next pharmacy claim post-index. Adherence used two definitions: proportion of days covered (PDC) and medication possession ratio (MPR). Multivariable analyses of non-persistence (hazard ratios) and adherence (odds ratios) were adjusted for baseline demographics, drug cost, clinical characteristics, and other anti-hyperglycemic agents.

Results: A total of 11,961 patients met all study selection criteria. Persistence rates at 12 months were significantly greater (p?p?=?0.83; PDC?=?0.79) and canagliflozin 300?mg (MPR?=?0.92; PDC?=?0.81) were greater than for the other index anti-hyperglycemic agents (MPR?=?0.33–0.75; PDC?=?0.33–0.72). Consistent results for treatment persistence and adherence were observed in multivariable analyses that were adjusted baseline characteristics.

Conclusions: Canagliflozin was associated with better treatment persistence and treatment adherence compared with other anti-hyperglycemic agents in real-world settings.     

信用如金:纳税信用评级披露与股价崩盘风险

本文以纳税信用评级披露为准自然实验,从股价崩盘风险的角度,考察作为社会信用体系重要组成的纳税信用对金融市场稳定的影响.研究发现,纳税信用评级披露后,评级高的企业股价崩盘风险显著降低.纳税信用评级披露通过发挥监督效应,提高企业信息透明度,抑制管理层的机会主义行为,同时发挥声誉保险效应,增强投资者信心,避免企业出现负面新闻时投资者因恐慌情绪抛售股票,从而降低股价崩盘风险.研究还表明,高纳税声誉对股价崩盘风险的降低作用对于民营企业和位于税收征管力度较低地区的企业更为显著.为此,应进一步完善包括纳税信用管理在内的社会征信体系,使健全的征信体系成为保障资本市场和金融体系稳定有效的重要基础.
