法典化目标下税法总则立法的三个问题

《民法典》开启了中国特色社会主义法治的法典化时代。法典化研究在多个法律领域都取得了进展和成果。随着税收法定原则加快落实,以税法总则为龙头的税法法典化被提上日程。税法法典化是历史的、逻辑的和现实的统一。其不仅是中国特色社会主义法治进程的重要组成部分,也符合近代历史以来世界法典化的普遍性规律。在法典化目标下,税法总则作为法典总则法、纳税人权利平衡法、税收行政行为规范法,又决定了其立法逻辑上有需要解决的一系列特殊问题。在此基础上,税法总则应构建税法原则、纳税人保护、纳税义务、税务行政规范制定与解释等支柱性制度。     

Earnings management by firms announcing earnings after SEC filing

This study examines motivation and stock market reactions of firms announcing earnings in the Wall Street Journal (WSJ) after filing with the Security Exchange Commission (SEC). Most firms announce earnings in the WSJ before SEC filing. Firms that reverse this sequence are voluntarily delaying public earnings announcements. The authors find that these firms are not only poor financial performers but also engage in earnings managements. They are delaying their WSJ announcements to postpone announcing bad news. The authors find significant stock price reactions to both the SEC filing and the WSJ announcement. The price reaction to earnings is incomplete at the SEC filings. The market continues reacting to firms' subsequent WSJ announcements as if the SEC filing fails to communicate earnings information to some investors.     

Tofacitinib in the treatment of moderate-to-severe rheumatoid arthritis: a cost-effectiveness analysis compared with adalimumab in Taiwan

Aims: Tofacitinib is an oral Janus kinase inhibitor for the treatment of rheumatoid arthritis (RA). This analysis investigated the cost-effectiveness of the second-line treatment with tofacitinib, compared with adalimumab, both plus methotrexate (MTX), in patients with moderate-to-severe RA and an inadequate response to the first-line MTX, from a Taiwan National Health Insurance Administration perspective.

Materials and methods: A patient-level simulation model was used to project lifetime costs and quality-adjusted life-years (QALYs). Base-case analysis compared second-line treatment with tofacitinib 5?mg twice daily plus MTX vs adalimumab 40?mg every 2?weeks plus MTX. Patients switched or discontinued treatment due to a lack or loss of effectiveness or a serious adverse event. Efficacy was measured by change in Health Assessment Questionnaire-Disability Index (HAQ-DI) score. HAQ-DI scores were used to predict mortality and resource utilization, and were mapped onto utility values to estimate QALYs. Efficacy and safety data were derived from clinical trials and other secondary sources. Uncertainty in model parameters was explored using one-way deterministic and probabilistic sensitivity analyses.

Results: Patients gained 0.09 more QALYs with second-line tofacitinib plus MTX compared with adalimumab plus MTX (5.13 vs 5.04, respectively) at an additional cost of New Taiwan Dollars (NT$) 12,881. The incremental cost-effectiveness ratio was NT$143,122/QALY. One-way sensitivity analysis confirmed the base-case result was robust.

Limitations: The lack of available clinical data, particularly for HAQ-DI scores, may introduce some bias in the analysis. No patients were in an early stage of RA, which may limit the generalizability of these results. Base-case results from our study are not necessarily generalizable to countries with healthcare systems that differ considerably from Taiwan.

Conclusions: From a payer perspective, second-line treatment with tofacitinib plus MTX is a cost-effective treatment strategy, compared with adalimumab plus MTX, in patients with moderate-to-severe RA in Taiwan.

生产要素对粮食产量的贡献系数分析

文章以河南省为案例,对2001年￣2003年全省109个县的数据进行定量分析,认为在既定的技术条件下,灌溉是影响粮食生产的第一要素,同时对其他要素的贡献系数又产生直接影响。灌溉对粮食产量贡献系数与当年的降水量密切相关。为保证粮食生产的稳定发展,政府应加强农田水利设施的建设,治理水污染,推广节水设备与技术,提高用水效率,同时对各种生产要素进行合理的配置。

企业核心竞争力价值测度、计量与会计报告研究

本文以企业核心竞争力是企业过去超额收益的价值表示为基本出发点,设计了包括直接测度法、间接测度法和评估测度法等三类企业核心竞争力的价值测度方法,还设计了“企业核心竞争力资源报表”等六张会计报表,对企业核心竞争力的存量、变量、存在状态和收益能力等进行会计报告。本文认为,企业核心竞争力既是可以计量的,又是可以记录的,而且还可以通过改进现有的财务会计报告体系与格式,对企业核心竞争力的状态予以报告。
