This paper discusses recent debt trends and evaluates performance of debt sus- tainability analysis (DSA) conducted in a sample of Sub-Saharan African (SSA) countries over the period 2008 – 16. Based on qualitative and quantitative analyses, the findings suggest the existence of systematic optimism bias in past DSA vintages resulting from optimistic macro-economic projections that underpin the DSAs. As a result, the DSAs for the sample countries analysed projected higher debt carrying capacities, which in most cases led to a faster pace of debt accumulation during this period. Moreover, this was not helped by the fact that average interest rates on new debt commitments were rising faster relative to gross domestic product growth rates, while the necessary fiscal adjustment to counter this development remained insufficient. Countercyclical policies supported by fiscal buffers that were used to address the impact of the 2008 global financial crisis have largely not been reversed despite the erosion of the buffers and a pick-up in growth in some countries. As a result, the overall risk of debt distress in the region has deteriorated in the past decade. Going forward, strengthening analytical/research work on country macroeconomic projections underlying their DSAs, relationship between investment and growth, impact of natural disasters on DSA frameworks and quantifying and monitoring fiscal risks would be important pieces of work in leveraging DSA results for financing and policy decisions. Other supporting issues to embrace include capacity building to enhance quality of policies, transparency and accountability at institutional level; managing roll over risk; developing and implementing sound debt management strategies. to these questions will help flag potential debt vulnerabilities and provide insight into the plausibility of macroeconomic frameworks used to underpin DSAs. The findings will also provide guidance on whether there is a need for a thorough scrutiny of the process leading to elaboration of assumptions underlying DSAs.

本文讨论了最近的债务趋势,并评估了2008-2016年期间在撒哈拉以南非洲(SSA)国家样本中进行的债务可持续性分析(DSA)的绩效。基于定性和定量分析,研究结果表明,由于支撑DSA的乐观宏观经济预测,在过去的DSA年份中存在系统的乐观偏见。因此,抽样国家的DSAs分析了预计更高的债务承受能力,这在大多数情况下导致这一时期债务积累的速度更快。此外,新债务承诺的平均利率相对于国内生产总值增长率的增长速度更快,而应对这一发展的必要规模调整仍然不够。尽管缓冲区受到侵蚀,一些国家的经济增长有所回升,但用于应对2008年全球金融危机影响的规模缓冲区支持的反周期政策基本上没有逆转。因此,该区域债务危机的总体风险在过去十年中有所恶化。展望未来,加强对国家宏观经济预测的分析/研究工作,这些预测基于其DSA、投资与增长之间的关系、自然灾害对DSA框架的影响,以及量化和监测规模风险,将是利用DSA结果进行融资和政策决策的重要工作。需要处理的其他支助问题包括:能力建设,以提高政策质量、透明度和机构一级的问责制;管理展期风险;制定和实施健全的债务管理战略。对这些问题的回答将有助于标记潜在的债务脆弱性,并深入了解用于支持DSAs的宏观经济框架的合理性。调查结果还将提供指导,说明是否有必要对导致详细说明DSA基础假设的过程进行彻底审查。对于MEFMI及其技术合作伙伴来说,调查结果将突出以下领域

Measuring Trade Cost Reductions Through a New Bridge in Mozambique: Who Benefits From Transport Infrastructure? 通过莫桑比克新桥衡量贸易成本降低:谁从交通基础设施中受益?

We use spatial maize prices in Mozambique to measure transport cost reductions, attribute these reductions to road distance and road quality and assess to what extent producers, traders and consumers benefit. For identification we exploit a unique natural experiment, the construction of a new road bridge over the Zambezi River, which connects the north and south of Mozambique. The applied methodology allows for potentially oligopolistic traders with spatially varying mark-ups. Estimations are based on monthly maize prices, in 22 markets, for 5 years before and after the introduction of the bridge. Estimates of transport cost reductions, averaged over routes, vary from 3% to 7%, with large heterogeneity between routes, and roughly for two-third due to road distance and for one-third due to road quality. On average benefits of trade cost reductions are equally shared between traders and consumers, but for larger distances, a larger part accrues to traders. The evidence also indicates a reduction in prices in destination markets due to the bridge. Results are supported by observed transport cost data, robust for non-random bridge placement and strict source-destination rules.
我们使用莫桑比克的玉米空间价格来衡量运输成本的降低,将这些降低归因于道路距离和道路质量,并评估生产者、贸易商和消费者的受益程度。为了进行识别,我们利用了一项独特的自然实验,即在连接莫桑比克北部和南部的赞比西河上建造一座新的公路桥。所应用的方法允许潜在的寡头垄断贸易商进行空间变化的加价。估计数基于大桥建成前后5年内22个市场的每月玉米价格。各路线的平均运输成本降低估计值在3%至7%之间,各路线之间差异很大,大约三分之二是由于道路距离,三分之一是由于道路质量。平均而言,降低贸易成本的好处在贸易商和消费者之间平均分配,但对于更远的距离,贸易商将获得更大的收益。证据还表明,由于大桥的修建,目的地市场的价格有所下降。观测到的运输成本数据、非随机桥梁布置的鲁棒性和严格的源-目的地规则支持了结果。

This paper lays the groundwork for more effective multisectoral action on reducing stunting, by analysing and generating empirical evidence useful for informing the joint targeting of nutrition-sensitive interventions in the countries in Sub-Saharan Africa. Using information from 33 recent Demographic and Health Surveys, measures are constructed to capture a child’s access to food security, care practices, healthcare and water, sanitation and hygiene (WASH), in order to identify gaps in access among different socio-economic groups and relate access to these nutrition drivers with nutrition outcomes. Three main questions are addressed. (a) What is the extent to which children have inadequate access to the underlying determinants of nutrition? (b) What is the association between stunting and overlapping deprivations in adequate food and care practices, health and WASH services? (c) What are the sectors that have the greatest impact on stunting?

Africa’s Development Debts 非洲的发展债务

Public debt levels in sub-Saharan Africa rose sharply in the wake of the global financial crisis, and a number of countries are now classified by the World Bank and International Monetary Fund as at high risk of debt distress. By contrast with the debt crisis of the 1980s and 1990s, however, concerns were not region wide as recently as early 2020, and the policy environment for growth remains robust for the majority of countries in the region. The external environment nonetheless poses a set of region-wide risks that include the economic effects of the COVID-19 pandemic and are exacerbated by the increase in market-based debt and the retreat of the Paris Club among official creditors. Changes in perceived creditworthiness can now drive distress, and new challenges of creditor coordination will complicate the debt restructuring process. We motivate a research agenda that focuses on development assets at risk as rising debt service obligations crowd out development as well as operational and maintenance budgets. Preserving and enhancing these assets, which include advances in human capital and infrastructure and an improved investment environment, should be a central objective of domestic policy actions, preventative debt restructurings and institutional approaches to debt distress.
在全球金融危机之后,撒哈拉以南非洲的公共债务水平急剧上升,许多国家现在被世界银行和国际货币基金组织列为债务危机的高风险国家。然而,与20世纪80年代和90年代的债务危机相比,直到2020年初,该地区的担忧还没有蔓延到整个地区,该地区大多数国家的增长政策环境仍然强劲。尽管如此,外部环境带来了一系列区域范围的风险,其中包括2019冠状病毒病大流行的经济影响,并因市场债务的增加和巴黎俱乐部官方债权人的退出而加剧。人们对信誉度的看法发生变化,现在可能引发困境,债权人协调方面的新挑战将使债务重组过程复杂化。我们推动了一项研究议程,重点关注面临风险的开发资产,因为不断上升的偿债义务挤占了开发以及运营和维护预算。保存和加强这些资产,其中包括人力资本和基础设施的进步以及投资环境的改善,应成为国内政策行动、预防性债务重组和解决债务困境的体制办法的中心目标。

Optimal Public Investment in Resource-Rich Low-Income Countries 资源丰富的低收入国家的最优公共投资

Recent studies have found that resource-rich low-income countries are better off investing their resource revenues domestically rather than saving them abroad in a sovereign wealth fund (SWF). This paper finds an optimal rule-based policy of accumulating public capital and its associated public investment path in a perfect foresight general equilibrium model. The model has several specific features different from the existing frameworks: the policy rule for public capital is introduced. Public investment is inefficient and has its absorptive capacity constraint costs. External savings clear the government budget. There is a variable share of resource revenues to accumulate the SWF, and the natural resource sector is assumed to be capital-intensive with its foreign direct investment shock. Based on calibration for African countries, the study finds that the front-loaded public investment path is optimal given an initial one-period resource windfall, public investment inefficiency and absorptive capacity constraints in the economies. This result also holds under less productive public capital and more patient households, while a scenario of no resource windfall produces the welfare loss due to a steady increase in consumption tax to finance public investment.
最近的研究发现,资源丰富的低收入国家最好将其资源收入投资于国内,而不是将其存入主权财富基金。本文在一个完全前瞻的一般均衡模型中找到了一个基于规则的公共资本积累最优政策及其相关的公共投资路径。该模型有几个不同于现有框架的具体特征:引入了公共资本的政策规则。公共投资效率低下,其吸收能力制约了成本。外部储蓄为政府预算扫清了障碍。资源收入中有一个可变的份额来积累主权财富基金,自然资源部门被认为是资本密集型的,其外国直接投资受到冲击。在对非洲国家进行校准的基础上,研究发现,考虑到最初一个时期的资源意外之财、公共投资效率低下和经济体的吸收能力限制,前期公共投资路径是最优的。这一结果也适用于生产力较低的公共资本和更有耐心的家庭,而由于为公共投资提供资金而稳步提高消费税,没有资源的意外之财会产生福利损失。

Path Dependence in Disability. 残疾的路径依赖

The average prevalence of disability in most African countries is 10%, but for many it exceeds the global disability prevalence rate of 15%. The extent to which this disability capturing functional and activity limitations results in permanent job loss, lowered lifetime income and assets, in part, depends upon the extent to which the onset of limitations becomes permanent. In this paper, we use five rounds of longitudinal data from rural Malawi, a low-income African country with high prevalence of disability, to examine path dependence in activity limitations. We estimate a dynamic linear panel data model where the coefficient on the one-period lagged health outcome captures path dependence in limitations. Our preferred Arellano-Bover estimates show that males experience partial persistence in both the incidence and intensity of severe limitations and no persistence in other limitations. Females, on the other hand, exhibit no persistence in any type of limitations. Our findings have important policy implications for computing the long-term costs associated with onset of activity limitations as these costs can be moderated by the recovery exhibited in these limitations.

大多数非洲国家的平均残疾发生率为 10%,但许多国家的残疾发生率超过了 15%的全球残疾发生率。这种功能和活动受限的残疾在多大程度上会导致永久性失业、终生收入和资产减少,部分取决于残疾的发生在多大程度上是永久性的。在本文中,我们使用了马拉维农村地区的五轮纵向数据来研究活动受限的路径依赖性,马拉维是一个低收入的非洲国家,残疾发生率很高。我们估计了一个动态线性面板数据模型,其中滞后一期的健康结果系数捕捉了活动受限的路径依赖性。我们首选的 Arellano-Bover 估计结果表明,男性在严重活动受限的发生率和强度方面具有部分持续性,而在其他活动受限方面则没有持续性。另一方面,女性在任何类型的限制方面都没有表现出持续性。我们的研究结果对于计算与活动受限相关的长期成本具有重要的政策意义,因为这些成本会因活动受限的恢复情况而有所缓和。

Natural Resources, International Commodity Prices and Economic Performance in Sub-Saharan Africa (1990–2019) 撒哈拉以南非洲的自然资源、国际商品价格和经济表现(1990-2019)

In this paper, we investigate the link between windfall gains and losses of income associated with commodity exports and economic performance in a panel of 45 sub-Saharan African (SSA) countries over the period from 1990 to 2019. Windfall gains and losses of income are measured in terms of fluctuations in a country-specific commodity terms of trade (CTOT) index in which each commodity is weighted by the ratio of exports of that commodity in the country’s gross domestic product (GDP). The CTOT index therefore reflects the commodity export specialisation for individual countries. The data on CTOT are taken from the International Monetary Fund. Additionally, we use changes in real GDP per capita as our SSA economic performance measure. We employ a random coefficient model that yields individual estimates for each of the countries included in the analysis. Our approach is based on the assumption that the effect of windfall gains and losses on real GDP per capita growth varies across different SSA countries. Our main conclusion can be elaborated as follows: first, natural resources have undoubtedly contributed to higher economic growth in SSA countries since 1990. Second, when SSA countries are analytically divided into two groups depending on their commodity export specialisation, we find that resource-rich countries—in particular oil rich—are the best economic growth performers during the observation period. Finally, we find that windfall gains from commodity exports are not significantly associated with increased real GDP per capita growth in most agriculture-exporting countries.
在本文中,我们研究了1990年至2019年期间45个撒哈拉以南非洲(SSA)国家与商品出口相关的意外收益和损失与经济表现之间的联系。收入的意外收益和损失是根据一国特定商品贸易条件指数的波动来衡量的,在该指数中,每种商品以该商品出口占该国国内生产总值的比例加权。因此,CTOT指数反映了单个国家的商品出口专业化程度。CTOT的数据来自国际货币基金组织。此外,我们使用实际人均GDP的变化作为我们的SSA经济绩效衡量标准。我们采用随机系数模型,对分析中包括的每个国家产生单独的估计。我们的方法基于以下假设:意外收益和损失对实际人均GDP增长的影响在不同的SSA国家有所不同。我们的主要结论可以阐述如下:第一,自1990年以来,自然资源无疑对SSA国家的较高经济增长做出了贡献。其次,当SSA国家根据其商品出口专业化程度被分析分为两组时,我们发现资源丰富的国家——尤其是石油丰富的国家——在观察期间是经济增长表现最好的国家。最后,我们发现,在大多数农业出口国,大宗商品出口的意外收益与实际人均GDP增长的增加没有显著关联。

Second, when SSA countries are analytically divided into two groups depending on their commodity export specialisation, we find that resource-rich countries—in particular oil rich—are the best economic growth performers during the observation period. Finally, we find that windfall gains from commodity exports are not significantly associated with increased real GDP per capita growth in most agriculture-exporting countries.","PeriodicalId":51524,"journal":{"name":"Journal of African Economies","volume":" ","pages":""},"PeriodicalIF":1.6,"publicationDate":"2021-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46007829","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Challenges in Changing Social Norms: Evidence from Interventions Targeting Child Marriage in Ethiopia 改变社会规范的挑战:来自埃塞俄比亚针对童婚的干预措施的证据

We study a set of interventions in Ethiopia geared towards eliminating child marriage. The interventions facilitate community discussion about child marriage and provide economic incentives for girls to stay in school and remain unmarried. Changing social norms is often thought of as very difficult, and if there is a marriage penalty to being among the first to deviate to an older age of marriage, raising the typical age at first marriage could be especially challenging. Regardless, using weighting and a difference-in-differences approach, we find that both interventions reduce the probability a girl from 8 to 17 years old has been married by about 4 to 7 percentage points. We observe some positive spillover effects: the program appears to have increased the intra-household decision-making power of women. However, we also find suggestive evidence of increased polarisation in beliefs about child marriage, including some possible backlash especially among men. No robust effects were seen on education outcomes, suggesting that, in contrast to other studies, this was not the mechanism through which the intervention had an effect.
我们研究了埃塞俄比亚旨在消除童婚的一系列干预措施。这些干预措施促进了社区对童婚的讨论,并为女孩留在学校和未婚提供了经济激励。改变社会规范通常被认为是非常困难的,如果第一批偏离结婚年龄的人会受到婚姻惩罚,那么提高初婚的典型年龄可能尤其具有挑战性。无论如何,使用加权和差异分析法,我们发现这两种干预措施都将8至17岁女孩结婚的概率降低了约4至7个百分点。我们观察到一些积极的溢出效应:该计划似乎增加了妇女的家庭内部决策权。然而,我们也发现了关于童婚信仰两极分化加剧的暗示性证据,包括一些可能的反弹,尤其是在男性中。没有发现对教育结果的强烈影响,这表明,与其他研究相比,这不是干预产生影响的机制。

Investment Motives in Africa: What Does the Meta-Analytic Review Tell? 非洲的投资动机:元分析评论说明了什么?

Over the past two decades, Africa has witnessed a dramatic increase in foreign direct investment (FDI) despite a lack of significant changes in infrastructure and the host country’s policies. What are the motives to invest in Africa? How do these investment motives differ for firms from developed and emerging markets? Several studies empirically tested these questions, however, provided inconclusive results. By taking 735 estimates extracted from 51 studies and applying advanced meta-analysis techniques, this study examines the motives of FDI in Africa. We found that compared to market-seeking motive, the effect size of resource seeking and efficiency seeking is larger (smaller) on FDI attractiveness in Africa. In terms of effect size, the impact of asset-seeking motive on FDI is statistically comparable to that of market-seeking motive. Contrary to general perceptions, the impact of natural resources on FDI attractiveness in Africa is not different from market seeking for developed countries’ firms. Our results show that compared to GDP per capita, the effect size of accessing minerals and oil reserves on FDI attractiveness in Africa is positive and significant for global and emerging market firms. Our research shows that there is more likelihood of type I and type II publication selection bias in this research field.
在过去二十年中,尽管基础设施和东道国的政策没有发生重大变化,但非洲的外国直接投资却急剧增加。在非洲投资的动机是什么?这些投资动机与发达市场和新兴市场的公司有何不同?然而,对这些问题进行实证检验的几项研究却没有得出结论。通过从51项研究中提取735个估计值,并应用先进的荟萃分析技术,本研究考察了非洲外国直接投资的动机。我们发现,与市场寻求动机相比,资源寻求和效率寻求对非洲外国直接投资吸引力的影响大小更大(更小)。就效应大小而言,资产寻求动机对FDI的影响与市场寻求动机的影响在统计上具有可比性。与一般看法相反,自然资源对非洲外国直接投资吸引力的影响与发达国家企业寻求市场没有什么不同。我们的研究结果表明,与人均GDP相比,获取矿产和石油储量对非洲外国直接投资吸引力的影响大小对全球和新兴市场公司来说是积极和显著的。我们的研究表明,在这一研究领域,I型和II型出版物选择偏差的可能性更大。
