This paper establishes a nonparametric estimator for the treatment effect on censored bivariate data under unvariate censoring. This proposed estimator is based on the one from Lin and Ying(1993)'s nonparametric bivariate survival function estimator, which is itself a generalized version of Park and Park(1995)' quantile estimator. A Bahadur type representation of quantile functions were obtained from the marginal survival distribution estimator of Lin and Ying' model. The asymptotic property of this estimator is shown below and the simulation studies are also given 相似文献

Many firms that sell digital copies of copyrighted materials online face a common dilemma: the use of digital rights management (DRM) to impede pirates can impose restrictions on legitimate use. We introduce a two‐period model in which the use of DRM in the first period affects the probability that a consumer finds a pirated copy in the second period; the threat of legal action reduces consumers’ consumption of pirated copies; and firms choose whether to sell, and at what prices, either strongly or weakly DRM‐protected products, or both. Furthermore, we incorporate the role of uncertainty concerning future levels of piracy. Using a two‐period model with uncertainty, we investigate a firm's optimal DRM strategies and present the optimal pricing strategy as well as product launch strategy under different market conditions. We find that one important characteristic of the optimal strategy is that it is optimal to maintain the same product line configuration strategy for both periods. We also characterize the conditions under which each strategy is optimal. 相似文献

While the relationships between health insurance and the labor supply of women have been explored in the literature, little
is known about the effects of offering public health insurance on the labor supply decisions of married women. This paper
examines how the enactment of the State Children’s Health Insurance Program (SCHIP) affected the labor supply decisions of
married women. Our empirical analysis showed that certain groups of married women reduced their number of hours worked upon
SCHIP implementation. The results imply it is possible that some wives decreased their labor supply in order to make their
children eligible for public health insurance.

For the unbalanced one-way random effects model with heterogeneous error variances, we propose the non-informative priors for the between-group variance and develop the first- and second-order matching priors. It turns out that the second-order matching priors do not exist and the reference prior and Jeffreys prior do not satisfy a first-order matching criterion. We also show that the first-order matching prior meets the frequentist target coverage probabilities much better than the Jeffreys prior and reference prior through simulation study, and the Bayesian credible intervals based on the matching prior and reference prior give shorter intervals than the existing confidence intervals by examples. 相似文献

This study aims at ascertaining how Hong Kong people perceive Hong Kong as a harmonious society. It also identifies the elements
that are most conducive to social harmony in Hong Kong, so that the government could take reference when formulating new policies.
1,062 adults residents were asked to rate their perceived level of social harmony and their satisfaction with 36 items (divided
into three dimensions: public governance, society, and economy, family and work) for which the research team believes would
be influencing the perceived level of social harmony. Results show that the average rating of social harmony was 5.57 (out
of 10), delineating a moderate level of social harmony. Subsequent multivariate factor analysis and regression analysis show
that the four extracted factors (from the three dimensions) had significant impacts on the level of social harmony. These
were, in order of significance: (a) public governance, (b) social solidarity and respect, (c) economy/family/work and, (d)
social tolerance and progressiveness. According to the factor loadings of each significant factor, we identified four core
values which we hope the government would consider when formulating new policies, as follows: (1) A Justice Government with
Sincerity on Communication, (2) Mutual Support and Respect with Integrity and Dedication, (3) Dedication to One’s Job and
Community by Helping the Needed and, (4) Creativity and Progressiveness with Tolerance. Implications for policy making are
discussed.
The study was conducted under the direction and guidance of the Fostering Social Harmony Task Force of the Hong Kong Professionals
and Senior Executives Association (HKPASEA). The authors acknowledge the kind support and assistance provided by the Council
Members of HKPASEA and staff members of the Centre for Corporate Governance and Financial Policy at Hong Kong Baptist University.
We are also grateful to Prof. Alex Michalos and Prof. P. K. Ip for their comments and suggestions given at the International
Conference on National Well-Being held in November 2006 at the National Central University, Taiwan. 相似文献

In this paper, we consider some noninformative priors for the common mean in a bivariate normal population. We develop the first-order and second-order matching priors and reference priors. We find that the second-order matching prior is also an HPD matching prior, and matches the alternative coverage probabilities up to the second order. It turns out that derived reference priors do not satisfy a second-order matching criterion. Our simulation study indicates that the second-order matching prior performs better than the reference priors in terms of matching the target coverage probabilities in a frequentist sense. We also illustrate our results using real data. 相似文献
