两种"公地悲剧"的比较与我国国有企业产权调整

对比两种“公地悲剧”的产权结构、成因和解决方式,可以发现产权结构调整与资源配置效率相适应是一个不断的试错过程,有效的产权制度必然促使成本与收益向行为者集中。产权结构调整与产权束调整是产权制度创新的主要方式。无论何种方式的产权制度变革都需遵循一定的规则,其调整的目的是降低交易成本、提高产权效率、增加产权主体收益。

Variance estimation based on blocked 3×2 cross-validation in high-dimensional linear regression

In high-dimensional linear regression, the dimension of variables is always greater than the sample size. In this situation, the traditional variance estimation technique based on ordinary least squares constantly exhibits a high bias even under sparsity assumption. One of the major reasons is the high spurious correlation between unobserved realized noise and several predictors. To alleviate this problem, a refitted cross-validation (RCV) method has been proposed in the literature. However, for a complicated model, the RCV exhibits a lower probability that the selected model includes the true model in case of finite samples. This phenomenon may easily result in a large bias of variance estimation. Thus, a model selection method based on the ranks of the frequency of occurrences in six votes from a blocked 3×2 cross-validation is proposed in this study. The proposed method has a considerably larger probability of including the true model in practice than the RCV method. The variance estimation obtained using the model selected by the proposed method also shows a lower bias and a smaller variance. Furthermore, theoretical analysis proves the asymptotic normality property of the proposed variance estimation.     

离婚案件网络虚拟财产的分割——以淘宝网店为例

我国《民法总则》明确了网络虚拟财产受法律保护,这是财产保护的一大进步,但是理论和实践中,网络虚拟财产却存在着性质和权属难以确定、分割和继承规则不明确等一系列问题。对涉及淘宝网店财产分割的审判案例进行数据分析,发现审判实践中存在着财产分割没有法律依据、价值难确定、归属不公平的困境。针对这些困境,在对夫妻网络虚拟财产进行分割时要注意保护虚拟财产的特殊性,提前明确共同财产范围,组织多机构联合评估价值,保护人身利益。

通过文献参阅,运用现代经济学和社会学相关理论和方法,探索性地分析集体耕作制时期,农地产权残缺、社会的高度封闭性及平均分配主义的影响和中国农村人口的快速增长。改革开放30年来,影响中国农村人口快速增长的诸因素和人口低生育水平反弹的压力基本消除。面对人口长期负惯性增长的新趋势,中国应及时调整生育政策。     

对成都市在“城乡一体化”改革中创新突破的调查和研究

城乡统筹发展的实质就是要协调城市与乡村的各类要素资源,打破城、镇、乡、村的脱节和工业与农业发展不平衡的格局,实现以城乡一体化为目标、以改革创新为核心、以群众利益最大化为宗旨、以市场化为动力、以政策为保障的城乡和谐与可持续发展。     

知识产权被许可人的诉权性质探析——以二元知识产权体系为理论视角

当知识产权遭受到侵害时,不仅知识产权权利人的权益受到了损害,知识产权被许可人的权益也受到了损害.然而,在符合法律规定的诉讼中,被许可人的诉权性质如何,尚无定论,这是一个在理论上和实践中都非常重要的问题.尽管我国有关的法律对被许可人的诉权作出了一些规定,但是关于被许可人的诉权性质在理论和实践上仍有必要做进一步的探讨.在二元知识产权体系理论的框架下,上述问题将会得到很好的解决.

Limits to “Jewish power”: how Slovak Jewish leaders negotiated restitution of property after the Second World War

This article examines how Jewish leaders in post-war Slovakia negotiated the restitution of property with the legislative and executive powers in Bratislava and Prague. The Jewish leaders were affiliated with two Slovak Jewish organisations founded in 1945: the Central Union of Jewish Religious Communities in Slovakia (Ústredný sväz ?idovských nábo?enských obci na Slovensku, ÚS?NO) and the Organisation of Victims of Racial Persecution at the Hands of the Fascist Regime in Bratislava (Sdru?enie fa?istickým re?imom rasovo prenasledovaných v Bratislave, SRP). The Secretary General of the SRP, Dr Vojtech Winterstein, was the main voice negotiating and promoting the interests of the post-war Jewish community. His invaluable collection of documents – the Winterstein collection – provides the source base for this article.
