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. 相似文献

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.Trial registration: ClinicalTrials.gov identifier: NCT00853385. 相似文献

This article evaluates the effects of budget consolidation on the Australian economy in the 1990s. As the economy recovered from the 1991–92 recession, the need to improve the fiscal balance to lift national saving became the dominant influence on fiscal policy. The article argues that spending cuts by the Australian federal government announced in 1996 had immediate effects on financial markets, with reduced long‐term interest rates of about 50 basis points in 1996–97. Using a modified version of the Treasury macroeconometric model of the Australian economy (TRYM), the article simulates the net macroeconomic effects of the expenditure cuts, fiscal consolidation and lower long‐term interest rates. The article finds that the program of budget consolidation had a sizeable short‐ and medium‐term impact on the economy, raising Gross Domestic Product by up to three‐quarters of a percentage point and reducing unemployment by 0.3 percentage points over the next two to three years. 相似文献

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。 相似文献

基尼系数分解分析中国城市居民收入不平等 总被引:7,自引:0,他引:7
当GINI系数按组(如职业,性别,区域)分解时,它可以分为组内、组间和层迭项(overlapped)三个组成部分,从文献检索来看,GINI系数的分解方法已有许多,但大多数分解方法不仅不易于理解而且计算非常繁重.本文应用Yao和Liu(1996)提出的四步分解法克服了其他方法存在的缺点,并以中国2003年的城镇居民收入调查数据为例,说明这个新方法可以容易地应用于研究中国各地区城市居民间收入的不平等状况.本文在许多以前的研究未能认识到的层迭带部分有实质性的突破. 相似文献
