知识产权证券化的制度缺失与完善

知识产权证券化是以知识产权进行融资的活动,在实践中需要相关的制度支持和保障.知识产权证券化具有促进知识产权市场化与产业化的功能,也具有促进知识产权研究开发和融资的功能.我国目前缺乏有关知识产权证券化的基本法律制度,也缺乏具体的实施细则.我国现有的制度对知识产权证券化形成制约,妨碍知识产权证券化的实践.在知识产权证券化的发行主体的设立方面,受到我国公司制度的制约.在知识产权证券化的证券发行与转让上,受到我国证券法律制度的制约.对于金融创新成果的知识产权证券化,可以在不改变现有的有关基本制度的前提下,制定单行规则,时机成熟时再完善有关的基本制度.知识产权证券化同时也具有风险性,也要有防范风险的制度保障.     

信息技术革命背景下的后现代社会消费文化

科学技术作为一种重要的生产力要素,在社会文化以及消费文化的发展中扮演者重要的、基础性的角色.当代信息技术革命,不仅给后现代社会的政治、经济、社会、文化、生活等产生了深刻的影响,并且或直接或间接地影响着后现代社会的消费文化,使其出现了一些前所未有的趋势与特点.本文在其他学者研究的基础上,首先对当代信息技术革命前的后现代社会及其消费文化进行了较系统的概括和论述,然后着重阐述了信息技术革命对后现代社会产生的新影响以及后现代社会消费文化的新发展.

The effects of income transfers on poverty reduction in people with disabilities in South Korea

Using a nationally representative sample dataset from the 2016 Korean Welfare Panel Study, we examined the anti‐poverty effects of income transfers in people with disabilities. Our findings indicate that in households with a person with a disability, income transfers decreased by 55.9% and 84.8% of the pre‐transfer poverty rate and poverty gap, respectively. Before income transfers, households with a person with a disability were 1.94 times more likely to be poor compared to those without a person with a disability. When income transfers were offered, the chance of being poor in the disability group was only 1.11 times higher than that in the non‐disability group. Findings from the aggregated data suggest that means‐tested income transfers were more effective in reducing poverty levels than social insurance or private income transfers. At the individual level, the provision of means‐tested programs was also more likely to decrease the likelihood of experiencing poverty than social insurance and private income transfers.     

Copula-based reliability analysis for a parallel system with a cold standby

The traditional reliability models cannot well reflect the effect of performance dependence of subsystems on the reliability of system, and neglect the problems of initial reliability and standby redundancy. In this paper, the reliability of a parallel system with active multicomponents and a single cold-standby unit has been investigated. The simultaneously working components are dependent and the dependence is expressed by a copula function. Based on the theories of conditional probability, the explicit expressions for the reliability and the MTTF of the system, in terms of the copula function and marginal lifetime distributions, are obtained. Let the copula function be the FGM copula and the marginal lifetime distribution be exponential distribution, a system with two parallel dependent units and a single cold-standby unit is taken as an example. The effect of different degrees of dependence among components on system reliability is analyzed, and the system reliability can be expressed as the linear combination of exponential reliability functions with different failure rates. For investigating how the degree of dependence affects the mean lifetime, furthermore, the parallel system with a single cold standby, comprising different number of active components, is also presented. The effectiveness of the modeling method is verified, and the method presented provides a theoretical basis for reliability design of engineering systems and physics of failure.

Optimal Bandwidth Selection in Heteroskedasticity–Autocorrelation Robust Testing

This paper considers studentized tests in time series regressions with nonparametrically autocorrelated errors. The studentization is based on robust standard errors with truncation lag M=bT for some constant b∈(0, 1] and sample size T. It is shown that the nonstandard fixed‐b limit distributions of such nonparametrically studentized tests provide more accurate approximations to the finite sample distributions than the standard small‐b limit distribution. We further show that, for typical economic time series, the optimal bandwidth that minimizes a weighted average of type I and type II errors is larger by an order of magnitude than the bandwidth that minimizes the asymptotic mean squared error of the corresponding long‐run variance estimator. A plug‐in procedure for implementing this optimal bandwidth is suggested and simulations (not reported here) confirm that the new plug‐in procedure works well in finite samples.     

Public Access to Government Information in the Digital Age: Findings from China

The openness of government information is an unavoidable issue in the digital age. The Chinese government makes great effort to publish administrative information and seek advice on good governance from the general public, but is nonetheless unable to meet citizens’ legitimate demands for the right to know and participate. This study analyzes this contradiction from four angles: the driving force, the type of information, the access platform, and the annual examination and supervision system for government information disclosure. The findings showed that (a) netizens’ heavy pressure rather than Chinese authorities’ strong leadership pushes forward the disclosure of government information; (b) administrative information concerning the public agenda rather than the policy agenda best meets the needs of the general public; (c) commercial Weibo websites are a more satisfactory channel than official government websites for practical requests; and (d) as a unique institutional arrangement for examination and supervision, the annual report on government information disclosure should be standardized.     

Bayes Factor Consistency for One-way Random Effects Model

In this article, we consider Bayesian hypothesis testing for the balanced one-way random effects model. A special choice of the prior formulation for the ratio of variance components is shown to yield an explicit closed-form Bayes factor without integral representation. Furthermore, we study the consistency issue of the resulting Bayes factor under three asymptotic scenarios: either the number of units goes to infinity, the number of observations per unit goes to infinity, or both go to infinity. Finally, the behavior of the proposed approach is illustrated by simulation studies.
