劳动力转移对城乡居民收入差距的非线性影响研究

借鉴已有相关研究成果,将劳动力转移、农业技术水平与城乡居民收入差距联系起来思考,可以具体地考察劳动力转移对城乡居民收入差距的影响.文章以农业技术水平作为门槛变量,选取2009—2019年中国31个省份的面板数据,利用泰尔指数测定城乡收入差距,以劳动力转移作为核心解释变量构建面板门槛模型,实证得出劳动力转移对城乡居民收入差距的非线性影响.研究发现:劳动力转移可以缩小城乡居民收入差距,且该影响具有单一门槛效应.在农业技术水平较低时,劳动力转移对城乡居民收入差距收敛效应较小;当农业技术水平越过门槛值达到较高水平后,劳动力转移对缩小城乡居民收入差距的效果几乎增加了一倍.此后,通过替换解释变量泰尔指数为城乡人均可支配收入比、替换核心解释变量农业技术水平为农业生产效率重新建立面板门槛模型,发现上述结论仍然成立,其检验结果具有较强的稳健性.文章将农业技术进步、劳动力转移、城乡居民收入差距这三个重要变量纳入同一模型框架中,在加深劳动力流动影响城乡居民收入差距这一视角的研究的同时,对缩小城乡居民收入差距政策的制定提供了重要的参考意义.     

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.     

地区收入、食品价格与恩格尔系数

本文以2016年我国31个省级地区截面数据为样本，构建扩展模型考察恩格尔系数与收入、食品价格之间的关系。研究发现，恩格尔系数与地区收入存在显著的负相关性，纳入食品价格后收入对恩格尔系数的影响变得更为显著，二者关系满足恩格尔定律。恩格尔系数和以地区食品价格平价代表的食品价格之间显著正相关，若再考虑其他因素，则食品价格对恩格尔系数的影响会稍有减弱。进一步将食品区分为生活必需型食品与非生活必需型食品，测算得到的基本恩格尔系数、高阶恩格尔系数与收入之间仍呈负相关关系，但与基本恩格尔系数相比，高阶恩格尔系数与收入之间的负相关性更弱。恩格尔系数受生活必需型食品价格的影响强于非生活必需型食品价格的影响，基本恩格尔系数主要受生活必需型食品价格的影响，而高阶恩格尔系数同时受到两类食品价格的影响。     

Mapping Right-Wing Women’s Policy Priorities in Latin America

ABSTRACT

Do right-wing women hold unique policy priorities from that of left-wing women and right-wing men? And do right-wing women legislators represent the priorities of right-wing citizens? Right-wing women share unique gendered socialization experiences with left-wing women, but their ideology informs values and attitudes critical to policy preference formation. Political representation theories suggest that women legislators should hold distinct incentives to represent female constituents. However, institutional theories suggest right-wing women legislators may face different incentives that limit the extent to which they represent right-wing female constituents. To evaluate our expectations, we leverage survey data from the Latin American Public Opinion Project and the Parliamentary Elites of Latin America. We demonstrate how right-wing women citizens differ from left-wing women citizens across a range of policy priorities. Then, we evaluate elite priorities for these same policy issues. We find little evidence for policy priority congruency between women citizens and women legislators on the right.     

Towards a performative understanding of deservingness: Merit,gender and the BBC pay dispute

Drawing largely on a high‐profile case of unequal pay at the BBC (British Broadcasting Corporation) as an illustrative example, this conceptual article considers differences and interrelationships between merit and deservingness, where the latter captures how, through appropriate performances, merit is given recognition and value. We propose a performative understanding of deservingness that highlights its gendered and embodied dimensions. Informed by Judith Butler's account of gender performativity, we show that, while merit is conventionally conceptualized as a relatively fixed set of attributes (qualifications, skill) 'attached' to the individual, deservingness captures how, in gendered terms, value and recognition are both claimed and conferred. As we argue, a gendered, deserving subject does not pre‐exist but is performatively constituted through embodied practices and performances of what is seen as worthy in a particular time and place.     

A class of additive transformation models for recurrent gap times

Abstract

The gap time between recurrent events is often of primary interest in many fields such as medical studies, and in this article, we discuss regression analysis of the gap times arising from a general class of additive transformation models. For the problem, we propose two estimation procedures, the modified within-cluster resampling (MWCR) method and the weighted risk-set (WRS) method, and the proposed estimators are shown to be consistent and asymptotically follow the normal distribution. In particular, the estimators have closed forms and can be easily determined, and the methods have the advantage of leaving the correlation among gap times arbitrary. A simulation study is conducted for assessing the finite sample performance of the presented methods and suggests that they work well in practical situations. Also the methods are applied to a set of real data from a chronic granulomatous disease (CGD) clinical trial.     

Compulsory income management: Combatting or compounding the underlying causes of homelessness?

Compulsory Income Management (CIM) is a form of conditional welfare that involves the mandatory quarantining of a portion of welfare recipients’ social security payments. Quarantined funds are accessible via a government-issued debit card, with restrictions surrounding where and on what funds can be spent. Official justifications of CIM have framed these policies as attempts to combat substance abuse and gambling problems, and to thus secure better outcomes for welfare recipients and their families. Central to this narrative has been the argument that welfare quarantining will ensure more money is spent on ‘essentials’, including accommodation. No existing studies, however, have specifically interrogated the impacts of CIM on housing security. This article responds to this gap in the literature by reviewing existing research concerning CIM's impacts and locating this research within broader debates regarding the causes of homelessness and the efficacy of individualised policy interventions. In doing so, it highlights CIM's potential to exacerbate housing insecurity not only through technical issues such as rental transfer failures, but also by contributing to underlying stressors such as economic disadvantage; relationship difficulties, poor health and addiction; and social stigma. The article concludes that – far from addressing the structural causes of homelessness – CIM has enflamed them.     

收入、预期寿命和社会养老保险收入再分配效应

本文在考虑职工基本养老保险典型不同缴费基数参保者寿命存在异质性的情况下，通过内部收益率的计算考察典型不同缴费基数参保者之间的养老金收入再分配效应。首先根据省级宏观截面数据估计了职工基本养老保险典型不同缴费基数参保者退休时的平均余命，再据此分别计算和比较不同参保群体的内部收益率。 研究发现职工基本养老保险制度总体上呈现微弱的正向收入再分配效应。虽然低缴费基数参保者内部收益率略高于中、高缴费基数参保职工，但其内部收益率因相对较短的寿命而大大降低。这也提醒政策制定者在研究制定延迟退休、社会养老保险全国统筹等政策时需要充分考虑参保职工内部不同群体间的平均预期寿命差别，对低收入参保者予以特别关注。     

金融集聚、生产率增长与城乡收入差距的实证分析——基于动态空间面板模型

本文利用中国2003-2013年285个地级及以上城市的统计数据，采用动态空间面板模型实证分析了金融集聚对城市总体生产率增长及其内部城乡收入差距的影响，研究结论表明：金融集聚是促进城市总体生产率增长的重要推动力，同时也是导致城市内部城乡收入差距扩大的关键因素，这主要是因为金融集聚显著推动了城市居民人均收入水平的提高，而对农村居民人均收入水平的提升作用不显著。本文的政策含义在于，在城市金融集聚的扩散阶段还没有到来之前，政府旨在缓解城乡收入差距的金融政策可能会抑制城市总体生产率增长。     

Exploring the generation gap in the workplace in South Korea

This study reviewed current literature on generational issues in Korea, specifically in relation to the workplace. Based on the results, this study concluded that distinct generations of workers exist in Korea. While there are similar generational characteristics between Korea and the United States because of the unique societal, historical, and cultural factors in each country, there are noticeable differences such as the existence of Generation 386 in Korea. Due to rapid industrialization and social transformation during the past few decades, Korean society seems to exhibit wider gaps between older and younger generations than the United States. The roles of Generation 386 and Generation Y in organizations should be considered for the future.
