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.     

A class of symmetric bivariate uniform distributions

A class of symmetric bivariate uniform distributions is proposed for use in statistical modeling. The distributions may be constructed to be absolutely continuous with correlations as close to±1 as desired. Expressions for the correlations, regressions and copulas are found. An extension to three dimensions is proposed.     

The residual effect of a growth-decay mechanism and the distributions of covariance structures

The product of two independent or dependent scalar normal variables, sums of products, sample covariances, and general bilinear forms are considered. Their distributions are shown to belong to a class called generalized Laplacian. A growth-decay mechanism is also shown to produce such a generalized Laplacian. Sets of necessary and sufficient conditions are derived for bilinear forms to belong to this class. As a generalization, the distributions of rectangular matrices associated with multivariate normal random vectors are also discussed.

通货紧缩的经济社会效应分析

通货紧缩作为经济运行中的一种常态现象 ,必然对经济、社会产生多方面影响。其效应表现为 :通过一般物价水平的下降以及对现存市场供求关系的破坏 ,对生产产生促退效应 ,导致失业率上升 ;总体上降低居民的消费能力 ;造成分配不公 ,导致社会财富由债务人向债权人、由国家向公众、由企业向消费者、由低收入者向高收入者的转移。针对通货紧缩的负效应 ,政府要采取措施 ,抑制分配不公 ,适当地向收入较低的普通百姓倾斜 ;企业要抓住机遇 ,尽快清理库存 ,同时狠抓技术创新、质量提高和内部管理 ,为新一轮发展作准备 ;居民要调整“买涨不买落”的传统心态 ,树立消费新观念。

青史凭谁定是非——评宋齐丘的历史功过

宋齐丘一生历经磨难和坎坷，曾四为宰相，贵为三公，助徐知诰“兴利除害，变更旧法”，并提出和推行了具有远见卓识的税制改革，戮力劝农，对吴、唐社会经济的发展作出了巨大的贡献，推动了历史的前进。他从此居功自傲，挟旧邀功，贪权固位．并长期卷入朝中朋党之争，最终葬送了自己。宋齐丘一生有功有过，但功大于过，是值得充分肯定的，应给其以公正的历史评价。
