"绝对的相对",抑或"相对的绝对"——汤森和森的贫困理论比较

英国经济学家彼得·汤森认为贫困是因为缺乏资源而被剥夺了享有常规社会生活水平和参与正常社会生活的权利,提出相对贫困测量方法.但是阿马蒂亚·森对此提出了质疑,认为贫困在能力的范围内是绝对的,相对贫困只是绝对贫困的补充而不能替代绝对贫困,是一种绝对的相对贫困观.本文对两人的贫困理论进行了比较和归纳.     

新疆贫困地区经济发展因素综合分析

贫困人口问题始终是关系到社会稳定和地区发展的重要问题。地处我国最西部的新疆地区的贫困人口更是与边疆稳定、团结少数民族等政治目标相联系。随着乡镇企业、非公有制经济及农业产业化经营的迅速发展,吸收消化了贫困地区农村大量剩余劳动力,改变了单纯农业结构,提高了农产品加工和服务业在贫困地区经济中所占比重,增加了财政收入。此外,随着西部大开发战略的实施以及第二欧亚大陆桥的沟通,新疆的外向型经济和旅游业也得到了空前未有的发展。这些成就在新疆贫困人口脱贫致富道路上起着很大的作用。但是有部分地区变化不大,有的则出现了反复,贫困状况未能得到根本改变。这些贫困地区的存在,始终影响着新疆经济的可持续发展。文章分析了其贫困特征及原因,指出这些地区脱贫致富的主要途径。     

Place in Entrepreneurial Storytelling: A Study of Cultural Entrepreneurship in a Deprived Context

We extend the cultural entrepreneurship perspective by investigating how entrepreneurs in deprived contexts gain legitimacy by leveraging proprietary and public places in their entrepreneurial storytelling. Inspired by the sociology of place, we present a longitudinal study of ten new venture journeys over four years in Kasoa, Ghana. We identify three distinct ways places are used in entrepreneurial narratives: projective significance of place, connective significance of place, and authoritative significance of place. We show how impoverished entrepreneurs construct and communicate places in diverse ways, not only as locations, but also as material and symbolic resources that provide legitimacy for their venturing activities. Drawing from our findings, we generate a model of place-based cultural entrepreneurship and elaborate place as a central resource in cultural entrepreneurship and new venture creation in deprived contexts.     

物价波动、收入增长和地区差距对中国贫困线的影响

我国贫困线的增长机制是只与物价挂钩,不与收入挂钩。由于食品价格增长高于消费价格指数增长,这种调整机制导致贫困线绝对购买力下降;同时,随着收入的快速增长,贫困线相对购买力急剧下降。另外,贫困线与地区经济发展水平高度相关,造成地区间受助穷人的生活质量相差巨大。     

计及外部性的储能系统价值测算及经济性评估

以应用在电力系统中的电储能系统为研究对象,以外部性理论为基础,构建了计及外部性的储能系统经济性测算模型,并以储能系统接入光伏电站为例,采用贴现现金流分析方法,预估储能投资成本和收益,分别从投资者角度和社会整体效益角度,来研究储能系统应用在可再生能源发电侧的经济性,并进行了盈亏平衡分析。通过盈亏平衡曲线分析了储能盈亏平衡情景,经济性分析结果显示储能系统的外部性收益占年收益比例较大。     

生态与经济发展的鸿沟

文章主要从词语来源与含义、研究对象的组织层次等方面系统地对比和阐述了生态学和经济学的接近或相似。生态学和经济学的学科性质和环境问题的日益严重决定了二者之间交叉学科的出现;经济学借鉴生态学,二者逐步走向融合。但由于＂生态＂是保守的,而＂经济＂是积极主动的,所以在经济与生态发展之间仍存在＂鸿沟＂。怎样处理和解决二者之间的矛盾,跨越＂鸿沟＂是摆在国内外学者们面前的一个重大课题。笔者认为,解决的途径仍应该是学科间的交融,这为科学研究提供了新的探索空间。     

The anatomy of fragile states in Sub‐Saharan Africa: Understanding the interrelationship between fragility and indicators of wellbeing

According to most classifications, Sub‐Saharan Africa is the region of the world with the highest presence of fragile states. In this paper we examine the relationship between fragility and poverty, suggesting that countries may become trapped in a vicious circle of fragility and low levels of wellbeing. We consider fragility as a continuum and begin by reviewing available measures. These show the high presence of fragility in Sub‐Saharan Africa and allow the more fragile countries to be identified. There is seen to be a strong association between fragility, poor growth performance, and lower wellbeing in Sub‐Saharan Africa. Building on the strong evidence for the two‐way relationship between economic growth and poverty, we present an analysis of how the vicious circle linking poorer welfare outcomes and fragility may be able to be broken. We argue that building successful institutions is key here, and this can be enabled by specific policy interventions that are both poverty reducing and productive.     

Fuzzy Chronic Poverty: A Proposed Response to Measurement Error for Intertemporal Poverty Measurement

A number of chronic poverty measures are now empirically applied to quantify the prevalence and intensity of chronic poverty, vis‐à‐vis transient experiences, using panel data. Welfare trajectories over time are assessed in order to identify the chronically poor and distinguish them from the non‐poor, or the transiently poor, and assess the extent and intensity of intertemporal poverty. We examine the implications of measurement error in the welfare outcome for some popular discontinuous chronic poverty measures, and propose corrections to these measures that seeks to minimize the consequences of measurement error. The approach is based on a novel criterion for the identification of chronic poverty that draws on fuzzy set theory. We illustrate the empirical relevance of the approach with a panel dataset from rural Ethiopia and some simulations.     

Inequality and Trade Policy: The Pro‐Poor Bias of Contemporary Trade Restrictions

This paper studies the pro‐poor bias of trade policy in India by estimating the household welfare effects of removing the current protection structure. The elimination of a pro‐poor trade policy is expected to have a negative differential welfare effect at the low end of the distribution. The paper first constructs trade restrictiveness indexes for household consumption items and industries using both tariffs and non‐tariff barriers. The results indicate that Indian trade policy is regressive through the expenditure channel as it disproportionately raises the cost of consumption for poorer households, while it is progressive through the earnings channel. Based on the net welfare effects, the elimination of the current trade protection structure is estimated to reduce inequality. These results indicate that a trade policy that is progressive through the earnings channel may induce a price effect that is regressive through the expenditure channel.     

India's Economic Reforms: Achievements and Next Steps

This paper reviews the impact of India's reforms since 1991 on the performance of the Indian economy. It shows that the reforms definitely achieved a significant acceleration in growth and they also succeeded in reducing poverty. However, they have been less successful in generating good quality jobs. There was progress in providing better access to education, health services ,and clean drinking water and sanitation, but less than was hoped. The area where performance has been most disappointing is environmental sustainability. The paper concludes by identifying some of the critical policy challenges in the years ahead.
