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

A MACROECONOMIC PERSPECTIVE OF AFTA'S PROBLEMS AND PROSPECTS 总被引:1,自引:0,他引:1
FRANCISCO D. A. NADAL DE SIMONE 《Contemporary economic policy》1995,13(2):49-62
The Association of Southeast Asian Nations (ASEAN) and the impressive economic performance of most of its members have increased the weight of the region's views in world fora. However, ASEAN has been unsuccessful in fostering a regional integration arrangement (RIA) leading to an increase in intraregional trade and foreign direct investment. In January 1992, ASEAN launched the Asean Free Trade Area (AFTA) seeking to establish a free trade area (FTA) by 2008.
Market integration increases economic interdependence and thereby raises the need for policy integration and discipline. This paper argues that a number of difficulties that ASEAN faced in promoting intraregional trade are likely to continue to affect AFTA (e.g., low economic complementarity and macroeconomic imbalances requiring large changes in equilibrium real exchange rates). The experience of other RIAs suggests other potential problems.
AFTA's prospects of evolving into deeper forms of sustainable integration are remote. Some cooperation in areas of common interest seems likely. 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

Measuring market response to regulation of the cable TV industry 总被引:2,自引:0,他引:2
During the 1988–1990 period, the cable television industry was subject to a number of regulatory events. These centered on possible reregulation of rates for basic service and reduction of entry barriers for potential competitors. Using the event study methodology on a portfolio of cable firms, we find evidence that news of no reregulation caused significant positive abnormal returns. News of reregulation caused insignificant negative abnormal returns. These findings provide some support for the traditional consumer protection theory of regulation. News related to entry barriers generally had no significant effect on returns, which suggests that elements of natural monopoly may exist in the industry. 相似文献

Inter-enterprise arrears in economies in transition 总被引:1,自引:0,他引:1
In the context of economies in transition, the paper argues that an excessive liquidity squeeze could throw the economy into a persistent state of low economic activity. In such bad equilibrium, enterprise transactions become largely demonetized, with a chain of arrears, a form of involuntary credit, spreading over the entire system. The empirical analysis of the Romanian experience seems to support the view advanced in the paper. 相似文献

Gadopentetate dimeglumine was administered intravenously to 16 patients undergoing abdominal magnetic resonance (MR) imaging. T1-weighted and fat-suppressed T1-weighted images were acquired before and after intravenous administration of 0.1 mmol/kg gadopentetate dimeglumine. The stomach, small bowel, and colon were analyzed regarding the presence and relative intensity of contrast enhancement. Diffuse enhancement of the gastrointestinal tract wall was observed in all patients following contrast material administration. Such enhancement was most conspicuous on fat-suppressed T1-weighted images. Quantitative measurements indicated that the wall of the gastrointestinal tract enhanced approximately 100% with gadopentetate dimeglumine. This study demonstrates that enhancement of the normal gastrointestinal tract occurs routinely when intravenous gadopentetate dimeglumine is administered, and such enhancement should not be considered indicative of gastrointestinal pathology. Furthermore, it suggests the potential utility for using intravenous rather than orally administered contrast agents to provide enhancement of the gastrointestinal tract on MR images. 相似文献
