A new generalized Weibull distribution in income economic inequality curves

Researchers have been developing various extensions and modified forms of the Weibull distribution to enhance its capability for modeling and fitting different data sets. In this note, we investigate the potential usefulness of the new modification to the standard Weibull distribution called odd Weibull distribution in income economic inequality studies. Some mathematical and statistical properties of this model are proposed. We obtain explicit expressions for the first incomplete moment, quantile function, Lorenz and Zenga curves and related inequality indices. In addition to the well-known stochastic order based on Lorenz curve, the stochastic order based on Zenga curve is considered. Since the new generalized Weibull distribution seems to be suitable to model wealth, financial, actuarial and especially income distributions, these findings are fundamental in the understanding of how parameter values are related to inequality. Also, the estimation of parameters by maximum likelihood and moment methods is discussed. Finally, this distribution has been fitted to United States and Austrian income data sets and has been found to fit remarkably well in compare with the other widely used income models.     

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.

中国近年来消费需求增长乏力的原因探析

消费需求增长乏力是近年来我国宏观经济面临的突出问题,这是居民消费能力、消费动力和消费环境三方面因素共同作用的结果。首先,居民收入增加与GDP增长不同步导致居民消费能力有限,而收入差距不断拉大则引起消费能力分配失衡;其次,未来收入和支出的预期不稳定、消费信贷制度滞后等在很大程度上降低了居民消费动力;最后,相关配套体制和设施不健全、与市场经济不协调的消费习惯等也都影响了消费需求的增加。     

中古吴兴武康姚氏之家风与家学--从一个侧面看文化因素在世族传承中的作用

吴兴姚氏起自汉末、孙吴时期 ,此后长期衰微 ,仕途不畅 ,沦为“贱族”。然因其有文化 ,姚氏不仅得以保持“素族”的本色 ,而且在南北朝后期有所振作 ,至唐代宦位荣显。由于儒家文化的熏染 ,姚氏子弟多有忠义与孝义之行。就其家学言 ,姚氏早期以通晓儒家经术知名 ,南北朝后期注重文史 ,至隋、唐终得大成。同时姚氏精于医术 ,在北朝倍受重视 ,这为其家族地位的上升提供了契机     

儒学的转型和文学的解构——论韩愈的思想与创作

“安史之乱”以后,唐代在思想与文学上都有一次解构潮流,而韩愈是这一潮流的重要代表。他在儒学道统中独宗孟子,其意在于以孟子的心学为起点来重铸儒学,以对抗佛学的心学,从而开辟了儒学的汉学到宋学的转型之路;韩愈的文道合一的思想也与他对儒学的重铸具有密切联系。另外,韩愈在诗文创作上虽以“复古”为口号,但实质上是解构一切旧的文体范式,以凌轹古人、创意造言为务。韩愈的解构实践和观点,在中国文学史上发生了很大的影响。     

中东恐怖主义发展中的宗教与战争因素

中东恐怖主义的发展与宗教和战争两大因素相关。伊斯兰名义下的暴力恐怖活动与反对帝国霸权和侵略战争紧密相连,恐怖主义的行为主体不仅仅是伊斯兰极端主义组织一方,还包括美国和以色列在侵略战争中所实行的国家恐怖主义。这种态势决定了中东恐怖主义现象的复杂性。认清这种复杂性,明确伊斯兰名义下的恐怖主义与伊斯兰复兴、伊斯兰教的联系与区别,避免误解和混淆,将有助于对中东形势及整个国际政治有准确而深刻的认识。     

1955年埃苏武器交易内幕

第二次世界大战后美英一方面为了对抗苏联,把中东拉进全球冷战范围,另一方面又企图通过1950年美英法三国宣言控制对中东的武器供应,进而达到调整、保持该地区政治和军事均势之目的。埃及总统纳赛尔为了抵抗以色列的袭击,在请求美英给埃及提供武器不成的情况下,毅然转向苏联,通过捷克同苏联签订了购买武器的条约。苏埃武器交易使苏联势力进入中东,从而给中东局势带来了深远的影响。     

Leveraging middle managers’ brokerage for corporate entrepreneurship: The role of multilevel social capital configurations

Building on recent efforts to bring a socio-political perspective to social capital research, we develop and test a multilevel framework that explains why middle managers who occupy brokerage positions differ in their ability and willingness to engage in entrepreneurial behavior. More specifically, we provide a contextualized understanding of the links among middle managers' brokerage, their political-support ties, and their personal initiative. Results derived from data on 383 middle managers and 72 top managers in 34 business units indicate that political-support ties with top managers strengthen the relationship between middle managers’ brokerage and personal initiative. However, this positive effect depends on the social capital resources available in the focal business unit. It is attenuated in business units with a supportive and trusting social context and amplified in business units with high levels of internal connectedness. By uncovering these incompatibilities and complementarities, our study demonstrates the value of accounting for different social capital configurations and the interplay of their inherent social capital resources when examining the effects of brokerage on corporate entrepreneurship.
