Targeting agricultural research based on potential impacts on poverty reduction: Strategic program priorities by agro-ecological zone in Nigeria

Growing concern for poverty in the face of declining agricultural research budgets has increasingly required formal priority setting of public agricultural research in developing countries to ensure that scarce research resources are allocated in ways that will have the greatest impact on the poor. This paper assessed the potential impacts of alternative commodity research programs on poverty reduction in three agro-ecological zones of Nigeria and identified strategic agricultural research priorities in the three zones. The paper discusses the poverty reduction-based priorities and their role in facilitating dialogue between research managers and policymakers aimed at sharpening the focus of agricultural research to achieve poverty reduction objectives in Nigeria.     

电力工业绿色和谐发展路径研究

PARETO HONOURING POVERTY REDUCTION

Policy reforms often pit the poor against the poor by triggering a fall in poverty for some but an increase in poverty for others. Aggregated national measures gloss over these fine patterns and pronounce ‘a reduction in poverty’– is such aggregation across poor individuals ethically permissible? Addressing this type of aggregation is a hard issue. This paper has made an attempt in that direction by outlining an axiomatically grounded aggregate measure of such gains or losses, duly giving more importance to the losses to a poor compared to the gains of another poor.

排污权有偿使用阶梯式定价研究——以化学需氧量排放为例

依据河南省2010年污染源普查数据,分析了不同行业化学需氧量排放的公平性问题,基于不同行业经济贡献与排污量之间的差异性的基础上,参考阶梯水价和电价的制定思路,提出了排污权阶梯式定价,并对其内涵与经济学特征进行了分析,最后,在恢复成本法定价的基础上制定了河南省化学需氧量有偿使用阶梯式价格。     

Allowing communities to trade in imperfectly competitive pollution-permit markets

Citizens and organizations representing them play an increasingly important role in markets for environmental quality, but much remains to be learned about how their participation affects these markets. We analyze the effects of allowing a community of citizens to trade pollution permits in an imperfectly competitive permit market. Allowing the community to trade directly reveals its preferences, which enhances welfare. However, community participation may also exacerbate distortions due to market power, even though the community itself trades competitively. Including the community in permit distribution may exacerbate market power distortions by affecting a dominant trader’s propensity to participate in the permit market. Second, the community’s demand/supply for permits may be more inelastic than other traders and worsen distortions due to market power. We illustrate in an example that these negative effects on competition can dominate the positive effect from preference revelation through the market place.      

Efficiency Gains Under Exchange-Rate Emission Trading

In the case of emission of non-uniformly dispersed pollutants such as SO2 the negative effects depend on the location of the sources. A unit increase at one source must be compensated by either a larger or smaller reduction at another source to keep the negative effects at the same level. Emission trading between countries is possible under the Second Sulphur Protocol. Exchange rate trading and third party problems are studied within a simultaneous model facilitating impositions of various environmental constraints. Simulations based on the negotiated emission quotas are offered. Results indicate potential cost savings of 19%.     

论我国碳排放权交易体系的构建

全球变暖是当今世界必须面对的重要环境问题,而碳排放权交易正是最有效的减排制度。目前,该制度在各国已得到广泛实践,而我国碳排放权交易体系的构建尚处于探索阶段。为此,我国应借鉴国际经验,选择适合中国的碳排放权交易机制,构建起有中国特色的碳排放权交易体系。     

Is the development of the agro-processing industry pro-poor?: The case of Thailand

We examine how the development of the agro-processing industry contributed to poverty reduction in Thailand. The effects on farmers’ income are emphasized because most of the poor in Thailand are farmers. The development of the agro-processing industry could improve farmers’ income through two channels: (i) the purchase of agricultural products; and (ii) the employment of the poor farmers at factories. We show that the development of the agro-processing industry, which also played a leading role in the high economic growth of the Thai economy, contributed to poverty reduction through both of the two channels. It was hence pro-poor.
