Restricted minimax estimation in semiparametric linear models

Abstract

In this article we develop the minimax estimation approach of general linear models to the semiparametric linear models when the parameters are simultaneously constrained by an ellipsoid and linear restrictions. Combining sample information and prior constraints the minimax estimator is obtained and compared with partially least square estimator by theoretical and simulation methods.     

Beyond Piketty: A new perspective on poverty and inequality in India

The socio-economic literature has focused much on how overall inequality in income distribution (frequently measured by the Gini coefficient) undermines the “trickle down” effect. In other words, the higher the inequality in the income distribution, the lower is the growth elasticity of poverty. However, with the publication of Piketty’s magnum opus (2014), and a subsequent study by Chancel and Piketty (2017) of evolution of income inequality in India since 1922, the focus has shifted to the income disparity between the richest 1% (or 0.01%) and the bottom 50%. Their central argument is that the rapid growth of income at the top end of millionaires and billionaires is a by-product of growth. The present study extends this argument by linking it to poverty indices in India. Based on the India Human Development Survey 2005–12 – a nationwide panel survey-we examine the links between poverty and income inequality, especially in the upper tail relative to the bottom 50%, state affluence (measured in per capita income) and their interaction or their joint effect. Another feature of our research is that we analyse their effects on the FGT class of poverty indices. The results are similar in as much as direction of association is concerned but the elasticities vary with the poverty index. The growth elasticities are negative and significant for all poverty indices. In all three cases, the disparity between the income share of the top 1% and share of the bottom 50% is associated with greater poverty. These elasticities are much higher than the (absolute) income elasticities except in the case of the poverty gap. The largest increase occurs in the poverty gap squared – a 1% greater income disparity is associated with a 1.24% higher value of this index. Thus the consequences of even a small increase in the income disparity are alarming for the poorest.

网络原创文学何以不大气?

网络原创文学不大气和网络写手生存的文化背景有关,其原因有写手过于贴近生活、缺乏必要的反刍过程和写手缺乏刻骨铭心的痛苦的生存体验,以及受书写工具的制约等.     

构建我国错案责任追究制度的立论基础

权力制约理论是错案责任追究制度近代化、理性化的科学依据 ,也是构建我国错案责任追究制度的理论基础。我国文化传统的惯性和特殊的社会结构是构建我国错案责任追制度的现实基础 ;实体正义与程序正义并重则是我们构建这一制度的价值基础     

行政合同的基本特性

行政合同是行政主体为直接实现行政的目的或单纯为行政事务与他方订立的合同.在行政主体合同权利的限制、行政主体在合同中的特权、合同的瑕疵与救济方面,行政合同均存在有别于普通合同的特性.这些特性意味着行政合同具备自身存在的理论基础和实践价值.     

西部经理人激励约束机制现状调查与实证分析--以西安市中小企业为例

运用调查问卷的方法,对西安市中小企业激励约束机制的现状、满意度、现存问题和影响因素等方面进行调研并做出了相关性分析,结果表明(1)西安市中高层管理人员对现有的激励机制不满意;(2)独立董事制度并没有起到相应的监督作用;(3)组织机构层次与信息的变失程度呈强的线性相关性.提出了建立健全信道系统,将激励约机制与市场环境相适应,重视经营者股权激励等方面的建议.     

试论权力制约与监督的法律制度

有了权力,就同时产生了对权力的制约和监督问题,世界各国都十分重视法律监督模式和效果的探讨,我国对权力监督制约机制还存在许多问题,法律监督制度尚不完善,而法律监督体制构建的关键,在于形成权力的制约机制和充分考虑并确保法律监督的权威和效力。     

论我国著作权法不应放弃强制许可制度

强制许可制度兴起于美国，后来迅速扩及英国以及大陆法系各国。《保护文学艺术作品伯尔尼公约》和《世界版权公约》对强制许可也作了详细规定。而我国作为两大公约的成员国，至今在现行的著作权法中仍未明文规定强制许可制度。事实上，目前在我国确定强制许可制度不仅是可能的，而且是必要的。     

网络社会各阶层的分析

网络社会是一种新的社会形态,其内部结构是不同接点组成的亚网络。具有相同信息编码的接点就是网络社会的一个阶层。由互联网重构的网络社会,结构上可分为三个大类,在每个大类下面又可以分成若干阶层。网络社会的每一个阶层之间也存在着不平等,如果这种不平等演变出巨大的数字鸿沟,将给现实世界带来新的社会问题。
