This paper describes Bayesian methods for life test planning with Type II censored data from a Weibull distribution, when the Weibull shape parameter is given. We use conjugate prior distributions and criteria based on estimating a quantile of interest of the lifetime distribution. One criterion is based on a precision factor for a credibility interval for a distribution quantile and the other is based on the length of the credibility interval. We provide simple closed form expressions for the relationship between the needed number of failures and the precision criteria. Examples are used to illustrate the results.Received: October 2002 / Revised: March 2004 相似文献

倾销幅度测算是裁定倾销以及实施反倾销措施的依据和基础。然而,具体操作过程中存在的偏颇之处,使得调查结果总是倾向发现“倾销幅度”,从而裁定倾销存在。本文以倾销幅度测算过程中的不合理之处为分析对象,举例说明了在很多情况下,原本不存在的倾销行为,是如何在现行的规定下被测算出了“倾销幅度”。 相似文献

实质性阻碍损害标准是指倾销进口产品严重地阻碍了进口国一个相同产品新产业的建立。作为反倾销法中损害认定三种损害类型中的一种,国际反倾销协议和各国反倾销法包括发达国家如加拿大的反倾销法对其规定得都较为概括模糊,因此有必要对加拿大国际贸易法庭对有关实质性阻碍的案例解释进行分析,以明确该损害标准的适用规则。从实质性阻碍客体之认定和实质性阻碍因素之认定两个方面对实质性阻碍案例解释进行分析。 相似文献

汇率决定理论的新近发展:文献综述 总被引:15,自引:0,他引:15
传统汇率决定理论对于现实经济中汇率实际变动情况的解释能力十分低下.20世纪80年代以来,学术界不断寻求突破,以期为汇率如何决定这一基本命题提供更为合理的解释.在这一过程中,不断有新的文献出现,从不同的方面对传统的汇率理论进行补充、发展和替代.鉴于此,本文试图对汇率决定理论的新近发展进行梳理和介绍,借以为国内经济学界研究汇率决定问题提供一个理论参考. 相似文献

This paper reports the results of the quantitative analysis of international experience of the relationship between infrastructure investment in the deployment of capacity that can carry large volumes of voice and data traffic and regulatory policy changes in the telecommunications sectors. It looks at the relationship between infrastructure investment for these infrastructure assets and the access pricing régimes for local exchange carriers in the United States and Europe. It then looks at the relationship between various aspects of regulatory and institutional policy changes in Europe and how they affect access prices.The paper finds that a lower access price promotes greater deployment of digital technology among US incumbent local exchange carriers (ILECs). Based on this finding, it suggests that it is in the ILECs interest to have access to their networks encouraged.The European data for interconnection are recent and far reaching conclusions are not feasible, but the findings, however, suggest that competition has worked by facilitating new entry through decreasing interconnection prices, although path dependencies, of existing and traditional concepts, in the mindsets of operators as well as regulators, may account for these findings. 相似文献

There is growing concern that trade, by connecting geographically isolated regions, unintentionally facilitates the spread of invasive pathogens and pests – forms of biological pollution that pose significant risks to ecosystem and human health. We use a bioeconomic framework to examine whether trade always increases private risks, focusing specifically on pathogen risks from live animal trade. When the pathogens have already established and traders bear some private risk, we find two results that run counter to the conventional wisdom on trade. First, uncertainty about the disease status of individual animals held in inventory may increase the incentives to trade relative to the disease-free case. Second, trade may facilitate reduced long-run disease prevalence among buyers. These results arise because disease risks are endogenous due to dynamic feedback processes involving valuable inventories, and markets facilitate the management of private risks that producers face with or without trade. 相似文献

This paper examines whether the explanatory power of exchange rate models can be improved by allowing for cross-country asymmetries and non-linear effects of fundamentals. Both appear to be crucial. The samples include the USD versus pound and yen from 1982:10 to 2013:10, and automated model selection is conducted with indicator saturation. Several non-linear effects are significant at 1%. Further, many of the indicators present in the linear models are eliminated once allowing for non-linearities; suggesting some of the structural breaks found in previous work were an artifact of the misspecified linear functional form. These conclusions are robust to estimation using principal components. 相似文献
