传导机制·行为反应:兼论我国财政政策的有效性

财政政策的有效性取决于传导机制,尤其是传导机制中微观主体的反应及其行为调整,财政政策工具的有效性是体制约束、微观主体数量、消费倾向、预算约束、信息传递效率与政策工具作用时间的函数。在此基础上,我们重新解释了积极财政政策失灵的原因,并对稳健的财政政策工具选择问题进行了初步探索。

Pharmacovigilance in Clinical Trials: Current Practice and Challenges

In view of the MENA increasing participation in multinational trials and the increasing number of national/regional trials, this article explores potential areas of pharmacovigilance, requiring reform and provides recommendations for building a robust safety reporting system. Regulatory silence on expedited reporting requirements creates confusion for local sites that are part of multinational trials. Not allowing waiver for serious adverse events that are protocol specified or are study endpoints, along with lack of emphasis on causality as reporting criteria, adds substantial burden of uninformative cases for regulatory review. Despite global focus on Development Safety Update Report, local regulators are not yet insistent on real-time update of a drug’s cumulative safety profile. Issues like reporting requirements for generic trials, pregnancy reporting and lenient timeline for death/life-threatening events need attention. Finally, the need to formulate an all-encompassing local pharmacovigilance guideline, in sync with global practice cannot be overemphasized.

“言行一致”的资本市场反应——基于战略合作信息披露视角

作为一种典型的非财报信息,战略合作信息具有独特的价值,正受到资本市场越来越多的关注。以2007—2018年上市公司战略合作协议公告作为研究对象,采用人工评分法和文本分析法全面评价了战略合作信息披露质量,并探讨了信息披露质量、信息披露“言行一致”的“短期”市场反应及其对经营业绩的影响。研究发现,资本市场对战略合作信息披露持积极反应,即战略合作信息披露质量越高,信息披露窗口期股票超额累计收益率越高。同时,战略合作信息披露质量越高,战略合作越容易落地,即信息披露的“言行一致”性越强;公司治理水平的提高有助于强化上述“正向反馈”。此外,战略合作信息披露的“言行一致”性越强,上市公司超额累计收益率越高,经营业绩越好。但在民营企业中仅表现出超额累计收益率的提高,在国有企业中仅表现出经营业绩的提升。因此,战略合作信息的准确披露有助于利益相关者深刻理解上市公司的战略规划,对公司经营大有帮助,监管部门应加强对此类信息的披露要求和规范审核。     

Engendering Response: Professional Gesture and the Assessment of Eyesight in Optometry Consultations

Many of the procedures undertaken within healthcare require specialized forms of participation that may be unfamiliar, even disturbing, to patients or clients. The practitioner has to encourage and enable participation in the investigation in an appropriate fashion while preserving the structure and integrity of the procedure. In this article, we consider optometry and the deployment of a vision test, known as subject refraction, that provides data to help determine the characteristics of any corrective lens that may be required by clients. The procedure's ability to establish robust and reliable data relies upon the optometrist's ability to encourage the client to respond to a series of stimuli without consideration or reflection. That is, the client is required to produce an unwitting response—conduct that might be considered nonsymbolic rather than symbolic. In this article, we also consider the optometrist's talk and bodily comportment during subjective refraction and how it serves to shape and determine the quality of the client's response and participation, and in turn to produce reliable test results.
