ABSTRACT The Covid-19 pandemic has generated shocks that have affected the global economy. The study examined perceived changes in food security as well as finances and revenue of rural and urban households during Covid-19 pandemic in Nigeria. Data were sourced from the National Longitudinal Phone Survey executed between April and June 2020 by the National Bureau of Statistics in collaboration with the World Bank. Data were analysed using descriptive statistics and the Chi-Square test. Findings revealed 83 percent of urban households and 78 percent in rural were food insecure. About 83 percent of rural households and 79 percent of Urban perceived Covid-19 pandemic as a threat to household finances. Household finances dropped for 29.3 percent of urban and 31.5 percent of rural households while 30.5 percent of urban and 20.0 percent of rural households who operate family business had no revenue at all. The study concluded that the pandemic has worsened the food security situation of both rural and urban households and has also adversely affected rural and urban household finances. Given a new surge in the epidemic, the government should take cognizance of the disparities in the context in which the pandemic affects the rural and urban households in Nigeria.
2019冠状病毒病(Covid-19)大流行带来了冲击,影响了全球经济。该研究调查了尼日利亚2019冠状病毒病大流行期间农村和城市家庭在粮食安全以及财务和收入方面的变化。数据来自国家统计局与世界银行合作于2020年4月至6月开展的全国纵向电话调查。数据分析采用描述性统计和卡方检验。调查结果显示,83%的城市家庭和78%的农村家庭处于粮食不安全状态。约83%的农村家庭和79%的城市家庭认为Covid-19大流行对家庭财务构成威胁。29.3%的城镇家庭和31.5%的农村家庭财务状况下降,30.5%的城镇家庭和20.0%的农村家庭没有收入。该研究的结论是,疫情恶化了农村和城市家庭的粮食安全状况,也对农村和城市家庭的财务状况产生了不利影响。鉴于这一流行病再次激增,政府应认识到这一流行病影响尼日利亚农村和城市家庭的背景下存在的差异。

ABSTRACT The study draws inference on the impact of agricultural trade openness, total factor productivity (TFP) growth, and domestic agriculture support on food security in Africa. To retain estimates efficiency and consistency in the presence of complex error terms, we employed the Panel-Corrected-Standard-Error (PCSE) estimator on panel data spanning 2005–2016 for 13 African countries. Results suggest that agricultural trade liberalisation and TFP have significant and favourable effects. Moreover, we find that reducing agricultural support beyond distortion-free levels enhances food security. Further to trade openness, we call for export growth-oriented domestic support anchored on agricultural human-capital development, innovation, and research and development.
摘要本研究推断了农业贸易开放、全要素生产率增长和国内农业支持对非洲粮食安全的影响。为了在存在复杂误差项的情况下保持估计的效率和一致性,我们对13个非洲国家2005-2016年的面板数据采用了面板校正标准误差(PCSE)估计量。结果表明,农业贸易自由化和全要素生产率具有显著的有利影响。此外,我们发现,将农业支持减少到无扭曲水平之外,可以加强粮食安全。在贸易开放的基础上,我们呼吁以出口增长为导向的国内支持,以农业人力资本开发、创新和研发为基础。

ABSTRACT We examine whether there is a relationship between xenophobic attacks and the stock market value of supermarket groups in South Africa. We perform an event study analysis on significant incidents of violent attacks targeted at shops owned by foreigners in South Africa for the period 2006–2017. Using an event study approach with an augmented market model, we uncover evidence that the stock market perceives these events as bad news instead of good news for supermarkets having operations in South Africa and other parts of Africa, as they realise a decline in abnormal returns of about 2.57 percent. We interpret our findings as economic costs of xenophobic attacks emanating from the Johannesburg Stock Exchange. Our analysis attempts to shed light on the peace-building challenges and the potentially grim implications of xenophobia on economic activity in South Africa.
摘要:我们研究了南非超市集团的股票市场价值与仇外袭击之间是否存在关系。我们对2006-2017年期间南非发生的针对外国人商店的重大暴力袭击事件进行了事件研究分析。使用事件研究方法和增强市场模型,我们发现有证据表明,对于在南非和非洲其他地区运营的超市来说,股市认为这些事件是坏消息,而不是好消息,因为他们意识到异常回报率下降了约2.57%。我们将我们的调查结果解释为约翰内斯堡证券交易所仇外袭击的经济代价。我们的分析试图阐明建设和平的挑战以及仇外心理对南非经济活动的潜在严峻影响。

ABSTRACT Meat analogues are becoming widely accepted in high-income countries as substitutes for meat. As consumer acceptance of faux meat is beginning to follow a similar trend in South Africa, this study investigated the aspects of the product’s positioning that could be used to further grow the product’s market. Using data collected from 130 middle-income consumers in Mbombela, the study determined consumer perceptions of meat analogues. These were measured using composite indices extracted using principal component analysis, and these indices were regressed against the consumers’ purchase probability of meat alternatives. The study’s results showed that meat alternatives were perceived as a pricey symbol of class and status. This was found to have a two-sided effect on consumer behaviour. On one hand, the products' position encouraged purchase among the survey respondents and encouraged them to recommend the products to their peers and on the other, it discouraged consumption with their families. As this finding shows that meat analogues remain niche products in the study area, the study offers recommendations on ways to improve product performance in the niche market. It also suggests changes in the products’ marketing that could assist in launching them into the mainstream food market of South Africa.
摘要肉类类似物作为肉类的替代品在高收入国家越来越被广泛接受。随着消费者对人造肉的接受在南非开始遵循类似的趋势,这项研究调查了该产品定位的各个方面,这些方面可以用来进一步扩大该产品的市场。该研究利用从姆邦贝拉130名中等收入消费者那里收集的数据,确定了消费者对肉类类似物的看法。这些指标是使用主成分分析提取的综合指数进行测量的,并根据消费者购买肉类替代品的概率对这些指数进行回归。研究结果表明,肉类替代品被视为阶级和地位的昂贵象征。研究发现,这对消费者行为有双重影响。一方面,这些产品的地位鼓励了受访者的购买,并鼓励他们向同龄人推荐这些产品,另一方面,这也不鼓励他们与家人一起消费。由于这一发现表明,肉类类似物在研究领域仍然是小众产品,该研究就如何提高小众市场的产品性能提出了建议。它还建议改变这些产品的营销,这可能有助于将它们推向南非的主流食品市场。

ABSTRACT This study presents a novel way to measure the contribution of private extension to farm productivity for club data. Club data refers to any convenience sample obtained from a study group, consulting firm, cooperative or producer organisation. The study develops a stochastic frontier production function model with the inefficiency effects of pasture-based dairy farming in the Eastern Cape, South Africa. The analysis for 2012–2018 involves 49 adopter farms, and controls for inter-calf period, nutrient use efficiency and the amount of extension contact. Results are robust to functional form specification and there is no evidence of frontier-shifting technical progress for the Cobb Douglas or translog model, but there is a clear productivity benefit to engaging with the private extension service provider working locally (adoption). Productivity rises at 0.91–1.06% p.a. over time and by 1.54–1.62% p.a. with each extra year of the extension. Large farms close to the private extension provider’s base of operations benefit most from being in the group. This case study is important because it documents productivity growth in the period since 2010 and puts the effect of extension on productivity growth back on the local research agenda.
摘要本研究提供了一种新的方法来衡量俱乐部数据中私人推广对农场生产力的贡献。俱乐部数据是指从研究小组、咨询公司、合作社或生产者组织获得的任何便利样本。该研究开发了一个随机前沿生产函数模型,该模型考虑了南非东开普省牧场奶牛养殖的低效效应。2012-2018年的分析涉及49个领养农场,并对幼崽间时期、营养利用效率和扩展接触量进行了控制。结果对功能形式规范来说是稳健的,没有证据表明Cobb Douglas或translog模型的技术进步会发生前沿变化,但与在当地工作的私人扩展服务提供商合作(采用)会带来明显的生产力效益。随着时间的推移,生产力每年增长0.91-1.06%,每延长一年,生产率每年增长1.54-1.62%。靠近私人扩展提供商运营基地的大型农场从集团中受益最大。这个案例研究很重要,因为它记录了自2010年以来的生产力增长,并将延期对生产力增长的影响重新列入了当地的研究议程。

Are SACU countries self-sufficient in cereals? A dynamic panel analysis 南共体国家的谷物自给自足吗?动态面板分析

ABSTRACT Most countries within Southern Africa are reliant on cereal imports from South Africa, Zambia, and Zimbabwe. In the Southern African Customs Union (SACU) region, cereal insecure countries are often import-dependent. Changing income levels, pandemics, climatic conditions and the trade environment all create a wedge and put pressure on food self-sufficiency. This paper uses a robust dynamic approach of a five-country panel to investigate the key determinants of cereal self-sufficiency in the SACU region. Long-term and short-term effects of selected variables are tested using a dynamic panel data model. The key long-term drivers for cereal self-sufficiency are identified and the short-term results reveal that land surface and rainfall are statistically most significant at a level of ten percent. The Dumitrescu-Hurlin panel causality test suggests that SACU member states could propose further macroeconomic harmonisation and good governance to stabilise national income to cushion against the possible increased cost of cereal production especially in Lesotho, Eswatini and Namibia. The adoption of climate smart technology to safeguard against rainfall variability and reduce the carbon footprint is important to foster an increase in agricultural productivity. A lack of effective harmonised policies may lead to an acceleration in cereal production insecurity and increased poverty.
南部非洲的大多数国家依赖于从南非、赞比亚和津巴布韦进口谷物。在南部非洲关税同盟(SACU)区域,谷物不安全国家往往依赖进口。不断变化的收入水平、流行病、气候条件和贸易环境都造成了隔阂,对粮食自给自足造成了压力。本文采用五国小组的稳健动态方法来调查SACU地区谷物自给自足的关键决定因素。采用动态面板数据模型对所选变量的长期和短期影响进行了检验。确定了谷物自给自足的主要长期驱动因素,短期结果表明,在10%的水平上,陆地表面和降雨量在统计上最显著。dumitrescui - hurlin小组因果关系检验表明,SACU成员国可以提出进一步的宏观经济协调和良好治理,以稳定国民收入,以缓冲谷物生产成本可能增加的影响,尤其是在莱索托、斯威士兰和纳米比亚。采用气候智能型技术防止降雨变化和减少碳足迹,对于促进农业生产力的提高至关重要。缺乏有效的协调一致的政策可能导致谷物生产不安全状况加速恶化和贫困加剧。

ABSTRACT This article evaluates the adoption and impact of improved wheat varieties on rural farm household welfare measured by consumption expenditure per adult equivalent and productivity per hectare in rural Ethiopia. The study utilises cross-sectional farm household-level data collected in 2017/2018 from a randomly selected sample of 323 farmers in Arsi Highland of Ethiopia. We estimate the adoption and causal impact of improved varieties by utilising endogenous switching regression complemented with a binary propensity score matching methodology. This helps us estimate the productivity and welfare effect of technological adoption by controlling for the role of selection bias problem stemming from both observed and unobserved heterogeneity. Our analysis reveals a consistent result across models indicating that adoption enhances wheat productivity per hectare by 0.63 tons/ha and household welfare by 31%. Even farm households that did not adopt would benefit significantly had they adopted. Education, wheat price, farm machineries, crop rotation, row planting, social capital (such as informal network, core trust, and institutional trust), training on varieties selection, and information on seed availability are found to be the main drivers behind the adoption of improved wheat varieties.
摘要本文评估了改良小麦品种的采用及其对埃塞俄比亚农村农户福利的影响,衡量标准为埃塞俄比亚农村每成年当量的消费支出和每公顷生产力。该研究利用了2017/2018年从埃塞俄比亚阿尔西高地323名农民中随机抽取的横断面农户水平数据。我们通过利用内生转换回归和二元倾向得分匹配方法来估计改良品种的采用和因果影响。这有助于我们通过控制由观察到和未观察到的异质性引起的选择偏差问题的作用来估计技术采用的生产力和福利效应。我们的分析显示,各模型的结果一致,表明采用该方法可使每公顷小麦产量提高0.63吨/公顷,家庭福利提高31%。即使是没有领养的农户,如果他们领养了,也会受益匪浅。教育、小麦价格、农业机械、轮作、行种植、社会资本(如非正式网络、核心信托和机构信托)、品种选择培训和种子可用性信息被发现是采用改良小麦品种的主要驱动因素。

Producer prices, carcass classification and consumers’ willingness to pay for different sheep meat grades: an experimental auction approach 生产者价格、胴体分类和消费者购买不同等级羊肉的意愿:一种实验性拍卖方法

ABSTRACT South African sheep farmers receive different prices for animals of different age, carcass form and fat level. Older animals trade at a substantive discount to the younger animals due to the perceived tenderness and juiciness of the younger animal. There is however a question whether the size of the discount is warranted given that certain cuts from older animals are preferred by consumers for specific purposes. This paper applies an experimental auction combined with sensory tests to establish the consumers’ willingness to pay for sheep meat products from carcasses with different age categories. In this way the paper endeavours to test whether the price differentiation in the mind of the consumer (through its perceived intrinsic value) corresponds with the price differentiation at the abattoir level. Consumers’ sensory assessment results and average bid prices via the experimental auction indicated a difference in preference towards the three age classes for the stew meat, loin, and leg cuts respectively. The results validate previous results with trained panels and confirm the specific consumer preferences for specific cuts of different age categories. It was also found that the difference in the bids for different age categories was far smaller than the difference in abattoir prices for the different age categories.
南非羊农对不同年龄、胴体形态和脂肪水平的羊获得不同的价格。由于年轻动物的柔嫩和多汁性,年长动物的交易价格大大低于年轻动物。然而,有一个问题是,折扣的幅度是否合理,因为消费者出于特定目的更喜欢老年动物的某些切割。本文采用实验拍卖与感官测试相结合的方法,建立了消费者对不同年龄类别的羊肉胴体产品的购买意愿。通过这种方式,本文试图测试消费者心中的价格差异(通过其感知的内在价值)是否与屠宰场水平的价格差异相对应。消费者的感官评估结果和通过实验拍卖的平均出价分别显示了对炖肉、腰肉和腿肉三个年龄段的偏好差异。结果验证了之前的结果与训练小组,并确认了不同年龄类别的特定切割的特定消费者偏好。还发现,不同年龄类别的出价差异远远小于不同年龄类别的屠宰场价格差异。

ABSTRACT Farm households respond to market uncertainties and household demand for food commodities by diversifying their farm-level crop portfolio. However, it is unclear if farmers’ crop mix also responds to unpredictable climate variability. We use primary data from 267 randomly selected respondents and apply a multinomial logit model to test the hypothesis that crop portfolio choice is an ex-ante mechanism to manage climate risks in the absence of crop insurance. The results suggest that access to information on climate variability does influence the mix of maize, cassava, sweet potato, and sorghum, which smallholder farmers in Kisumu County, Kenya grow in various combinations. Access to credit services, farm size, gender of household head, farming experience, and distance to nearest market also influence the farm-level crop mixture. These findings imply that policies geared towards incentivizing a better crop choice portfolio at the smallholder farm level should address climate variability awareness. In addition, encouraging crop-variety mixes that are tolerant to climate risks would enhance resilience in food systems among these smallholder farmers.
摘要农业家庭通过多样化其农场层面的作物组合来应对市场的不确定性和家庭对粮食商品的需求。然而,目前尚不清楚农民的作物组合是否也会对不可预测的气候变化做出反应。我们使用来自267名随机选择的受访者的主要数据,并应用多项logit模型来检验作物投资组合选择是在没有作物保险的情况下管理气候风险的事前机制的假设。研究结果表明,获取气候变化信息确实会影响玉米、木薯、红薯和高粱的组合,肯尼亚基苏木县的小农户以各种组合种植玉米、木薯和红薯。获得信贷服务的机会、农场规模、户主性别、农业经验以及与最近市场的距离也会影响农场层面的作物组合。这些发现意味着,旨在激励小农户更好地选择作物组合的政策应该解决气候变化意识问题。此外,鼓励耐受气候风险的作物品种组合将增强这些小农户的粮食系统抵御能力。

ABSTRACT Digital agriculture solutions hold a promise to build agri-food food systems that are more efficient, environmentally sustainable, and inclusive, thereby contributing to the attainment of the Sustainable Development Goals. In most African countries, the rapid adoption of mobile phones and other digital tools have accelerated the deployment of agricultural services for farmers and other value chain actors resulting in enhanced access to information, knowledge, financial services, markets, and farm tools. In addition, the COVID-19 pandemic has provided a unique opportunity to fast-track the deployment of contact-free digital solutions along the agri-food value chains. Despite the numerous opportunities presented by the digital agricultural revolution, its potential to transform agri-food systems in Africa remains uncertain. With a broad perspective on Africa, this paper explores the emerging evidence on digital agricultural services including key drivers, evidence on impact, and the effects of the COVID-19 pandemic. The paper concludes with some implications for policy makers and professionals in agricultural economics.
摘要数字农业解决方案有望建立更高效、环境可持续和包容性的农业食品系统,从而为实现可持续发展目标做出贡献。在大多数非洲国家,移动电话和其他数字工具的迅速普及加速了为农民和其他价值链参与者部署农业服务的速度,从而增加了获得信息、知识、金融服务、市场和农具的机会。此外,新冠肺炎大流行为沿着农产品价值链快速部署无接触数字解决方案提供了一个独特的机会。尽管数字农业革命带来了许多机会,但其改变非洲农业粮食系统的潜力仍然不确定。本文从非洲的广泛视角探讨了数字农业服务的新证据,包括关键驱动因素、影响证据和新冠肺炎大流行的影响。最后,本文对农业经济学的决策者和专业人士提出了一些启示。
