最低工资制度与初次分配中的公正问题

在“效率优先、兼顾公平”分配理念功能发生异化的情况下,着力解决初次分配中的公平问题尤为迫切,在现阶段主要是提高劳动报酬在初次分配中所占的比重,使以往GDP分配中劳动者收入偏低、资本所有者的回报偏高的畸形格局得到矫正,逐步完善最低工资制度,提高最低工资标准。

Psychosocial Care in Nursing Homes in the Era of the MDS 3.0: Perspectives of the Experts

Meeting psychosocial needs of nursing home residents is increasingly regarded as a critical component of care, and the nationally-mandated nursing home care screening instrument— the Minimum Data Set (MDS) 3.0—was modified and implemented in 2010 to promote better assessment of psychosocial needs and health. Recognizing the importance of psychosocial well-being among nursing home residents, and the promise of MDS 3.0 for improving psychosocial care, this article reports recommendations derived from a conference of stakeholders representing diverse disciplines and organizations regarding next steps following MDS 3.0 screening. Results relate to seven areas of psychosocial care and address cross-cutting recommendations to improve psychosocial care.     

China's social assistance policy: experiences and future directions

The Minimum Living Standard Guarantee System (MLSGS) forms the core of China's current social assistance policy, and special assistance programmes are used to supplement this policy. This paper scrutinizes the evolution and achievements of the social assistance policy, and analyses the challenges and problems that the policy faces. In this paper, we argue that the international trend of social assistance reforms, institutional background changes and the problems of social assistance in China require a developmental model to guide the future development of the social assistance policy. Therefore, social assistance policy should not only fulfil the basic living requirements of the underprivileged and enable underprivileged people to share the outcomes of economic and social development, but also should enable the underprivileged to develop human capital and participate in the labour market. To move towards developmental social assistance, this article proposes several relevant policy suggestions.     

A Note on the Frequency Polygon Based on the Weighted Sums of Binned Data

We revisit the generalized midpoint frequency polygons of Scott (1985), and the edge frequency polygons of Jones et al. (1998 Jones, M.C., Samiuddin, M., Al-Harbey, A.H., Maatouk, T. A.H. (1998). The edge frequency polygon. Biometrika 85:235–239.[Crossref], [Web of Science ®] , [Google Scholar]) and Dong and Zheng (2001 Dong, J.P., Zheng, C. (2001). Generalized edge frequency polygon for density estimation. Statist. Probab. Lett. 55:137–145.[Crossref], [Web of Science ®] , [Google Scholar]). Their estimators are linear interpolants of the appropriate values above the bin centers or edges, those values being weighted averages of the heights of r, r ∈ N, neighboring histogram bins. We propose a simple kernel evaluation method to generate weights for binned values. The proposed kernel method can provide near-optimal weights in the sense of minimizing asymptotic mean integrated square error. In addition, we prove that the discrete uniform weights minimize the variance of the generalized frequency polygon under some mild conditions. Analogous results are obtained for the generalized frequency polygon based on linearly prebinned data. Finally, we use two examples and a simulation study to compare the generalized midpoint and edge frequency polygons.     

The Minimum Density Power Divergence Estimation for the Lognormal Density

In this article, we implement the minimum density power divergence estimation for estimating the parameters of the lognormal density. We compare the minimum density power divergence estimator (MDPDE) and the maximum likelihood estimator (MLE) in terms of robustness and asymptotic distribution. The simulations and an example indicate that the MDPDE is less biased than MLE and is as good as MLE in terms of the mean square error under various distributional situations.     

非等间隔动态面板数据模型：基于半差分的估计方法和应用

本文提出了非等间隔动态面板数据模型的估计方法,包括非线性最小二乘和最短距离估计法以及这两种估计方法的一步估计量,并且证明了这几个估计量的一致性和渐进正态性。我们使用数值模拟的方法验证了这些估计在有限样本中的估计精度,并且将这四种估计方法应用于实际的问题当中,最终得到了与以往的文献基本一致的估计结果。     

Discourse change and policy development in social assistance in China

Zhang H. Discourse change and policy development in social assistance in China Since the introduction of a new social assistance programme in urban China, the state was eventually able to expand the programme to rural areas as a further step towards integrating the development of social assistance in urban and rural areas. This article argues that the development of social assistance in China can be explained by the change of discourse among the officials and the elites in central government. The discourse on social assistance can be conceptualised in three periods: the urban‐first discourse (1999–2003); the discourse debate (2003–2007); and the urban–rural integration discourse (2007–present). Through scrutinising specific discourses and the policy development of social assistance in these three periods, it appears that in company with the change in the discourse process, rural social assistance was developed rapidly in order to construct an integrated social assistance system. The article concludes that discourse plays a significant role in Chinese social assistance policy development.
