Agriculture and small towns in Africa

Africa is urbanizing rapidly. Yet most dual economy models focus on the sectoral rather than spatial dimensions of development. This article adopts a “dual–dual” approach to measuring rural/urban and farm/nonfarm linkages. We develop an economy‐wide model of Ethiopia that distinguishes between cities, towns, and rural areas. The model captures detailed sectoral and regional linkages, internal migration flows, and externalities from urban agglomeration. We find larger linkages between agricultural production and small towns and show that redirecting urban growth toward towns rather than cities leads to broader‐based economic growth and poverty reduction. In contrast, industry and services, particularly within cities, are far less effective in reaching rural areas and the poor. Africa's current urbanization pattern—toward major cities rather than towns—will weaken national growth–poverty linkages. Urbanization that takes advantage of the synergistic relationship between agriculture and small towns has the potential to result in a more inclusive growth trajectory.

中国沿海与内地贫困差异之解析:基于回归的分解方法

本文提出了一个分解框架,旨在量化相关决定因素对贫困空间差异或跨时变化的贡献。同时,本文引入了Shorrocks and Wan(2008)提出的数据生成法,以便将分组数据转化成微观个体数据。把这些方法论运用于中国,我们解析了中国内地与沿海城市间的贫困差异。研究结果表明,内地的高贫困主要归因于资源利用效率的低下而不是资源禀赋的欠缺;收入分配的不平等也是造成内地高贫困的又一重要原因。贸易、FDI等衡量经济开放度的指标与贫困之间的关系因时因地而不同。     

社会资本在减轻农村贫困中的作用：文献述评与研究展望

近年来,社会资本在减轻农村贫困中的作用逐渐成为发展经济学家关注的一个热点。本文分别从静态和动态两个视角综述了相关研究的思路和方法：从静态视角来看,信任对于减少绝对贫困有积极的作用,但某些形式的社会资本难以减轻绝对贫困,关于社会资本是否能减轻相对贫困则尚未取得一致的认识;从动态视角来看,社会资本通过非正式保险的机制平滑消费、减轻暂时贫困,通过促进融资和创业、保护产权、促进公共品提供和劳动力流动,有助于消除长期贫困。总的来看,随着市场化进程的深入,社会资本反贫困的积极作用有减弱的趋势。本文基于理论评述,提出了深化社会资本的减贫理论机制（尤其是对相对贫困的作用机制）、市场化进程中的社会资本反贫困机制、改进社会资本测量、加强因果效应识别等未来的研究方向。     

China's War on Poverty: Assessing Targeting and the Growth Impacts of Poverty Programs

In this paper, we attempt to assess the effectiveness of China's Poverty Alleviation Programs in contributing to economic growth in poor areas. To meet this overall goal, we briefly describe China's poor area policy and examine how its leaders have implemented one of the developing world's largest poverty alleviation programs. Second, we examine whether or not the poverty programs have been implemented in the parts of China that are truly poor. Finally, we attempt to assess if the poverty programs have affected growth. The major findings are that China's poverty programs do get implemented in areas of the nation that are poor, but there are many poor areas that have been left out of the government's various programs. We also find that poverty programs contribute to economic growth and that economic growth promotes poverty reduction.     

Spatial Comparisons of Poverty and Inequality in Living Standards in Malawi

The paper looks at poverty and inequality across areas in Malawi. The focus is on both monetary (consumption) and non‐monetary (health and education) dimensions of well‐being. Stochastic poverty dominance tests show that rural areas are poorer in the three dimensions regardless of poverty line chosen. Stochastic inequality dominance tests find that the north and south dominate the centre in health inequality, and there is no dominance between the north and south. With respect to education inequality, dominance is declared for the south‐centre pair only. A subgroup decomposition analysis finds that the south contributes the most to consumption and education poverty, while the centre is the largest contributor to health poverty. We establish that within‐area inequalities (vertical inequalities) rather than between‐area inequalities (horizontal inequalities) are the major driver of consumption, health and education inequality in Malawi.     

Can food-for-work encourage agricultural production?

Food-for-work (FFW) is the most widely used type of public works program in Ethiopia through which a high share of the food aid is distributed. This paper assesses the impacts of FFW in Tigray, a chronically food insecure region in Ethiopia, in terms of relieving liquidity constraints and thereby improving input use in agriculture. A Heckman selection model on the adoption and intensity of fertilizer use demonstrated that FFW positively influenced the decision to adopt fertilizer and there was no evidence of disincentive effect.     

How are we doing on poverty and hunger reduction? A new measure of country performance

The paper presents a new composite indicator – the poverty and hunger index (PHI) – to measure countries’ performance toward achieving millennium development goal No.1 (MDG1) on halving poverty and hunger by 2015. Building on the statistical structure of the human development index, the PHI combines all five official MDG1 indicators, thereby generating insights on a country’s net progress towards its own goal, as opposed to progress measured by a single yardstick. Nonparametric analysis on the PHI components provides further evidence on the nature of the relationship between poverty and hunger measures, while cross-country results show significant variance in progress between and within regions. An extension of the PHI allows for consideration of the rate of progress made by each country in its own terms; that is, based on where it needs to be to attain all 5 MDG1 targets by 2015. Countries needing priority attention are identified, as well as areas for future research and recommendations for post-2015 initiatives.     

REAL AND DISTRIBUTIVE EFFECTS OF PETROLEUM PRICE LIBERALIZATION: THE CASE OF INDONESIA

The effect of higher petroleum prices on the aggregate price level, real growth, and income distribution is appraised within a multisector computable general equilibrium (CGE) model. A reduction in the government subsidy raises petroleum prices and production costs throughout the economy. Consumer demand, production, and income decline as output prices increase and consumer purchasing power decreases. The model is applied to and calibrated for Indonesia. The simulated results predict a slight increase in the price level and a slight decrease in output. An important result is that urban household groups will be the most significantly affected by the subsidy reduction.
