Despite decentralization reforms of education systems worldwide, there is little empirical evidence about the processes through which decentralization can improve student learning. Proponents theorize that devolving decisionmaking authority to the local level can improve communication, transparency, and accountability, making teachers and school principals more responsible for better performance and more capable of bringing it about. Yet some research has shown that decentralization can increase inequality and reduce learning for disadvantaged students. This article reports on retrospective evaluations of three Central American school-based management reforms. Using matching techniques, these evaluations investigate whether the reforms enhanced student learning and how they affected management processes and teacher characteristics and behaviors. The evidence indicates that all three reforms resulted in substantive changes in management and teacher characteristics and behavior and that these changes explain significant portions of resultant changes in student learning. This article contributes to the understanding of how decentralization reforms can improve learning and shows how education reforms, even when not conceptualized as affecting teacher incentives, can generate important changes for teachers that, in turn, affect student learning.

尽管世界各地的教育系统都在进行权力下放改革,但很少有经验证据表明权力下放可以通过哪些过程改善学生的学习。支持者的理论是,将决策权下放到地方一级可以改善沟通、透明度和问责制,使教师和校长对更好的表现更负责,也更有能力实现这一目标。然而,一些研究表明,权力下放会加剧不平等,减少弱势学生的学习。本文报告了对中美洲三项校本管理改革的回顾性评价。使用匹配技术,这些评估调查了改革是否促进了学生的学习,以及它们如何影响管理过程和教师的特征和行为。证据表明,这三项改革都导致了管理、教师特征和行为方面的实质性变化,这些变化解释了学生学习结果变化的重要部分。本文有助于理解权力下放改革如何改善学习,并展示了教育改革(即使没有被概念化为影响教师激励)如何能够为教师带来重要变化,进而影响学生的学习。版权所有作者2007。牛津大学出版社代表国际复兴开发银行/世界银行出版。版权所有。有关许可,请发送电子邮件:journals.permissions@oxfordjournals.org,牛津大学出版社。

This article highlights the progress in building a knowledge base on effective ways to increase access to justice for women who have experienced gender-based violence, offer quality services to survivors, and reduce levels of gender-based violence. While recognizing the limited number of high-quality studies on program effectiveness, this review of the literature highlights emerging good practices. Much progress has recently been made in measuring gender-based violence, most notably through a world health organization multi country study and demographic and health surveys. Even so, country coverage is still limited, and much of the information from other data sources cannot be meaningfully compared because of differences in how intimate partner violence is measured and reported. The dearth of high-quality evaluations means that policy recommendations in the short run must be based on emerging evidence in developing economies (process evaluations, qualitative evaluations, and imperfectly designed impact evaluations) and on more rigorous impact evaluations from developed countries.
本文重点介绍了在建立有效方法知识库方面取得的进展,这些方法可以增加遭受性别暴力的妇女诉诸司法的机会,为幸存者提供优质服务,并减少基于性别的暴力程度。虽然认识到关于项目有效性的高质量研究数量有限,但本文献综述强调了新兴的良好实践。最近在衡量基于性别的暴力方面取得了很大进展,最显著的是通过世界卫生组织的多国研究和人口与健康调查。即便如此,国家覆盖范围仍然有限,由于衡量和报告亲密伴侣暴力行为的方式存在差异,来自其他数据来源的许多信息无法进行有意义的比较。由于缺乏高质量的评价,短期内的政策建议必须以发展中经济体的新证据(过程评价、定性评价和设计不完善的影响评价)和发达国家更严格的影响评价为基础。

The growing relationship between China and Sub-Saharan Africa : macroeconomic, trade, investment, and aid links 中国与撒哈拉以南非洲之间日益增长的关系:宏观经济、贸易、投资和援助联系

China’s economic ascendance over the past two decades has generated ripple effects in the world economy. Its search for natural resources to satisfy the demands of industrialization has led it to Sub-Saharan Africa. Trade between China and Africa in 2006 totaled more than $50 billion, with Chinese companies importing oil from Angola and Sudan, timber from Central Africa, and copper from Zambia. Demand from China has contributed to an upward swing in prices, particularly for oil and metals from Africa, and has given a boost to real gross domestic product (GDP) in Sub-Saharan Africa. Chinese aid and investment in infrastructure are bringing desperately needed capital to the continent. At the same time, however, strong Chinese demand for oil is contributing to an increase in the import bill for many oil-importing Sub- Saharan African countries, and its exports of low-cost textiles, while benefiting African consumers, is threatening to displace local production. China poses a challenge to good governance and macroeconomic management in Africa because of the potential Dutch disease implications of commodity booms. China presents both an opportunity for Africa to reduce its marginalization from the global economy and a challenge for it to effectively harness the influx of resources to promote poverty-reducing economic development at home.
中国在过去二十年的经济崛起在世界经济中产生了连锁反应。中国为满足工业化的需要而寻找自然资源,这使它来到了撒哈拉以南非洲。2006年中非贸易总额超过500亿美元,中国企业从安哥拉和苏丹进口石油,从中非进口木材,从赞比亚进口铜。来自中国的需求推动了价格的上涨,尤其是来自非洲的石油和金属,并推动了撒哈拉以南非洲地区的实际国内生产总值(GDP)。中国在基础设施方面的援助和投资为非洲大陆带来了亟需的资金。然而,与此同时,中国对石油的强劲需求,正导致许多撒哈拉以南非洲石油进口国的进口账单增加。中国出口的低成本纺织品,在惠及非洲消费者的同时,正威胁着取代当地的生产。中国对非洲的良好治理和宏观经济管理构成挑战,因为大宗商品繁荣可能导致荷兰病。对非洲来说,中国既是减少其在全球经济中被边缘化的机会,也是有效利用资源流入促进国内减贫经济发展的挑战。

Banking and Regulation in Emerging Markets : The Role of External Discipline 新兴市场的银行和监管:外部纪律的作用

This article reviews the main issues of regulating and supervising banks in emerging markets with a view toward evaluating the long-run options. Particular attention is paid to Latin America and East Asia. These economies face a severe policy commitment problem that leads to excessive bailouts and potential devaluation of claims of foreign investors. This exacerbates moral hazard and makes a case for importing external discipline (for example, acquiring foreign short-term debt). However, external discipline may come at the cost of excessive liquidation of entrepreneurial projects. The article reviews the tradeoffs imposed by external discipline and examines various proposed arrangements, such as narrow banking, foreign banks and foreign regulation, and the potential role for an international agency or international lender of last resort. Liberalization and integration of financial markets have been associated with an increase in capital movements and with the financial crises. In particular, surges in foreign short-term debt have been blamed for crisis episodes in emerging economies in Asia (Thailand, Indonesia, and the Republic of Korea) and Latin America (Mexico, Brazil, Ecuador, and Argentina), as well as in the periphery of Europe (Turkey). These crises have proved costly in terms of output. Several policy responses have been suggested. Among them have been the reduction of short-term debt, the development of stock markets, the improved regulation and supervision of domestic financial system, enhanced transparency requirements and market discipline, and the establishment of an international lender of last resort. A catalog of “solutions” has been proposed to take care of the problems of banking in emerging market economies including moving to a narrow bank system, building a currency union, and leaving banking in the hands of foreign banks and offshore institutions.

本文回顾了监管和监督新兴市场银行的主要问题,以评估长期选择。特别注意的是拉丁美洲和东亚。这些经济体面临严重的政策承诺问题,导致过度纾困和外国投资者债权的潜在贬值。这加剧了道德风险,并为引入外部纪律(例如,购买外国短期债务)提供了理由。然而,外部纪律可能以企业项目过度清算为代价。本文审查了外部纪律所带来的权衡,并审查了各种拟议的安排,如狭义银行、外国银行和外国监管,以及国际机构或国际最后贷款人的潜在作用。金融市场的自由化和一体化与资本流动的增加和金融危机有关。特别是,外国短期债务激增被认为是亚洲新兴经济体(泰国、印度尼西亚和韩国)、拉丁美洲(墨西哥、巴西、厄瓜多尔和阿根廷)以及欧洲外围国家(土耳其)爆发危机的原因。事实证明,就产出而言,这些危机代价高昂。已经提出了若干政策对策。其中包括减少短期债务、发展股票市场、改进对国内金融系统的管理和监督、加强透明度要求和市场纪律以及建立国际最后贷款人。为解决新兴市场经济体的银行业问题,各方提出了一系列“解决方案”,包括转向狭义银行体系、建立货币联盟,以及将银行业交给外国银行和离岸机构。本文确定了适合新兴市场和发展中经济体需求的政策应对措施。问题是监管政策和

What are the underlying rationales for industrial policy? Does empirical evidence support the use of industrial policy for correcting market failures that plague the process of industrialization? This article addresses these questions through a critical survey of the analytical literature on industrial policy. It also reviews some recent industry successes and argues that public interventions have played only a limited role. Moreover, the recent ascendance and dominance of international production networks in the sectors in which developing countries once had considerable success implies a further limitation on the potential role of industrial policies as traditionally understood. Overall, there appears to be little empirical support for an activist government policy even though market failures exist that can, in principle, justify the use of industrial policy.
产业政策的基本原理是什么?经验证据是否支持使用产业政策来纠正困扰工业化进程的市场失灵?本文通过对产业政策分析文献的批判性调查来解决这些问题。它还回顾了一些最近的行业成功,并认为公共干预只发挥了有限的作用。此外,国际生产网络最近在发展中国家曾经相当成功的部门中占据优势和主导地位,这进一步限制了传统上所理解的工业政策的潜在作用。总体而言,尽管存在市场失灵,原则上可以证明使用产业政策是合理的,但似乎很少有经验支持积极的政府政策。

More than regulations, laws on the books, or voluntary codes, enforcement is a key to creating an effective business environment and good corporate governance, at least in developing countries and transition economies. A framework is presented to help explain enforcement, the impact on corporate governance when rules are not enforced, and what can be done to improve corporate governance in weak enforcement environments. The limited empirical evidence suggests that private enforcement tools are often more effective than public tools. However, some public enforcement is necessary, and private enforcement mechanisms often require public laws to function. Private initiatives are often also taken under the threat of legislation or regulation, although in some countries bottom-up, private-led initiatives preceded and even shaped public laws. Concentrated ownership aligns incentives and encourages monitoring, but it weakens other corporate governance mechanisms and can impose significant costs. Various steps can be taken to reduce these costs and reinforce other corporate governance mechanisms. But political economy constraints, resulting from the intermingling of business and politics, often prevent improvements in the enforcement environment and the adoption and implementation of public laws.
至少在发展中国家和转型经济体,执法是创造有效的商业环境和良好的公司治理的关键,而不是规章、成文法律或自愿守则。本文提出了一个框架来帮助解释强制执行、不强制执行规则对公司治理的影响,以及在强制执行不力的环境中可以采取哪些措施来改善公司治理。有限的经验证据表明,私人执法工具往往比公共工具更有效。然而,某些公共执法是必要的,而私人执法机制往往需要公法发挥作用。尽管在一些自下而上的国家,私人主导的倡议先于甚至影响了公法,但私人倡议也往往是在立法或监管的威胁下采取的。集中的所有权使激励机制一致,并鼓励监督,但它削弱了其他公司治理机制,并可能带来巨大的成本。可以采取各种措施来降低这些成本并加强其他公司治理机制。但是,由于商业和政治的混合而产生的政治经济限制,往往阻碍了执法环境的改善,也阻碍了公法的采纳和实施。

Mounting evidence suggests that excessive job protection reduces employment and labor market flows, hinders technological innovations, pushes workers into the informal sector, and hurts vulnerable groups by depriving them of job opportunities. Flexible labor markets stimulate job creation, investment, and growth, but they create job insecurity and displace some workers. How can the costs of such insecurity and displacements be minimized while ensuring that the labor market remains flexible? Each of the main unemployment income support systems (unemployment insurance, unemployment assistance, unemployment insurance savings accounts, severance pay, and public works) has strengths and weaknesses. Country-specific conditions, chief among them labor market and other institutions, the capacity to administer each type of system, and the size of the informal sector, determine which system is best suited to developing and transition countries.
越来越多的证据表明,过度的就业保护减少了就业和劳动力市场流动,阻碍了技术创新,迫使工人进入非正规部门,并因剥夺了弱势群体的就业机会而伤害了他们。灵活的劳动力市场刺激了就业机会的创造、投资和增长,但也造成了就业不稳定,并使一些工人失业。如何在确保劳动力市场保持灵活性的同时,将这种不安全和流离失所的成本降至最低?每一种主要的失业收入支持制度(失业保险、失业援助、失业保险储蓄账户、遣散费和公共工程)都有其优缺点。各国的具体条件,主要是劳动力市场和其他体制、管理每种制度的能力以及非正规部门的规模,决定了哪种制度最适合发展中国家和转型期国家。

Who is Not Poor? Dreaming of a World Truly Free of Poverty 谁不穷?梦想一个真正没有贫困的世界
IF 8.1 1区 经济学 Q1 DEVELOPMENT STUDIES Pub Date : 2006-01-25 DOI: 10.1093/WBRO/LKJ002

When the World Bank dreams of 'a world free of poverty,' what should it be dreaming? In measuring global income or consumption expenditure poverty, the World Bank has widely adopted the $1 a day standard as a lower bound. Because this standard is based on poverty lines in the poorest countries, anyone with income or expenditures below this line will truly be poor. But there is no consensus standard for the upper bound of the global poverty line: above what level of income or expenditures is someone truly not poor? This article proposes that the World Bank compute its lower and upper bounds in a methodologically equivalent way, using the poverty lines of the poorest countries for the lower bound and the poverty lines of the richest countries for the upper bound. The resulting upper bound global poverty line will be 10 times higher than the current lower bound and at least 5 times higher than the currently used alternative lower bound of $2 a day. And in tracking progress toward a world free of poverty, the World Bank should compute measures of global poverty using a variety of weights on the depth and intensity of poverty for a range of poverty lines between the global lower and upper bounds. For instance, rather than trying to artificially force the global population of 6.2 billion (a billion is 1,000 million) into just two categories 'poor' and 'not poor,' with the new range of poverty lines the estimates would be that 1.3 billion people are 'destitute' (below $1 a day), another 1.6 billion are in 'extreme poverty' (above $1 a day but below $2 dollar a day), and another 2.5 billion are in 'global poverty' (above extreme poverty but below the upper bound poverty line).
当世界银行梦想“一个没有贫困的世界”时,它应该梦想什么?在衡量全球收入或消费支出贫困时,世界银行(World Bank)普遍采用每天1美元的标准作为贫困线下限。因为这个标准是基于最贫穷国家的贫困线,任何收入或支出低于这条贫困线的人都是真正的穷人。但是,对于全球贫困线的上限并没有统一的标准:超过什么收入或支出水平的人才算真正不贫穷?本文建议世界银行以方法上相同的方式计算其下限和上限,使用最贫穷国家的贫困线作为下限,使用最富裕国家的贫困线作为上限。由此产生的全球贫困线上限将比目前的下限高10倍,比目前使用的每天2美元的替代下限至少高5倍。在跟踪实现无贫困世界的进展时,世界银行应该根据全球下限和上限之间的一系列贫困线,利用对贫困深度和强度的各种权重来计算全球贫困指标。例如,而不是试图人为地迫使全球62亿人口(十亿10亿)分为两类“贫穷”和“不可怜,”与新范围的贫困线估计将有13亿人“贫困”(低于1美元一天),另一个16亿人“极度贫困”(上图1美元一天但低于每天2美元),另有25亿人在“全球贫困”(上图极端贫困但上界贫困线以下)。

In measuring global income or consumption expenditure poverty, the World Bank has widely adopted the $1 a day standard as a lower bound. Because this standard is based on poverty lines in the poorest countries, anyone with income or expenditures below this line will truly be poor. But there is no consensus standard for the upper bound of the global poverty line: above what level of income or expenditures is someone truly not poor? This article proposes that the World Bank compute its lower and upper bounds in a methodologically equivalent way, using the poverty lines of the poorest countries for the lower bound and the poverty lines of the richest countries for the upper bound. The resulting upper bound global poverty line will be 10 times higher than the current lower bound and at least 5 times higher than the currently used alternative lower bound of $2 a day.

Reducing the Incidence of Low Birth Weight in Low-Income Countries Has Substantial Economic Benefits 在低收入国家减少低出生体重发生率具有巨大的经济效益

Reducing the incidence of low birth weight not only lowers infant mortality rates but also has multiple benefits over the life cycle. This study estimates the economic benefits of reducing the incidence of low birth weight in low-income countries, both through lower mortality rates and medical costs and through increased learning and productivity. The estimated economic benefits, under plausible assumptions, are fairly substantial, at about $510 per infant moved from a low-birth-weight status. The estimated gains are primarily from increases in labor productivity (partially through more education) and secondarily from avoiding costs due to infant illness and death. Thus there may be many interventions to reduce the incidence of low birth weight that are warranted purely on the grounds of saving resources or increasing productivity.
减少低出生体重的发生率不仅可以降低婴儿死亡率,而且在整个生命周期中具有多种益处。这项研究估计了通过降低死亡率和医疗费用以及通过提高学习和生产力来减少低收入国家低出生体重发生率的经济效益。在合理的假设下,估计的经济效益相当可观,从低出生体重状态转移出来的婴儿每个约510美元。估计的收益主要来自劳动生产率的提高(部分是通过更多的教育),其次来自避免因婴儿疾病和死亡而产生的成本。因此,可能有许多干预措施,以减少低出生体重的发生率,这些干预措施纯粹是出于节省资源或提高生产力的考虑。

Insights on Development from the Economics of Happiness 从幸福经济学看发展

The literature on the economics of happiness in developed economies finds discrepancies between reported measures of well-being and income measures. One is the so-called Easterlin paradox: that average happiness levels do not increase as countries grow wealthier. This article explores how that paradox and survey research on reported wellbeing in general can provide insights into the gaps between standard measures of economic development and individual assessments of welfare. Analysis of research on reported wellbeing in Latin America and Russia finds notable discrepancies between respondent assessments of their own wellbeing and income or expenditure based measures. Accepting a wide margin for error in both types of measures, the article posits that taking such discrepancies into account may improve the understanding of development outcomes by providing a broader view on wellbeing than do income or expenditure based measures alone. It suggests particular areas where research on reported well-being has the most potential to contribute. Yet the article also notes that some interpretations of happiness research psychologist set point theory, in particular may be quite limited in their application to development questions and cautions against the direct translation of results of happiness surveys into policy recommendations.
有关发达经济体幸福经济学的文献发现,报告中的幸福指标与收入指标之间存在差异。一个是所谓的伊斯特林悖论:平均幸福水平不会随着国家变得更富裕而提高。本文探讨了这种悖论和对报告的总体幸福感的调查研究如何能够为经济发展的标准衡量标准与个人对福利的评估之间的差距提供见解。对拉丁美洲和俄罗斯报告的福祉研究的分析发现,受访者对自己福祉的评估与基于收入或支出的措施之间存在显著差异。这篇文章承认这两种测量方法都有很大的误差余地,它认为考虑到这种差异可能会提高对发展结果的理解,因为它提供了一个比单独基于收入或支出的测量方法更广泛的关于福利的观点。它提出了一些特定的领域,在这些领域中,报告幸福感的研究最有可能做出贡献。然而,这篇文章还指出,对幸福研究心理学家设定点理论的一些解释,特别是在应用于发展问题方面可能相当有限,并警告不要将幸福调查的结果直接转化为政策建议。
