The aim of this research is to examine what antecedents of supply chain financing (SCF) should be overcome to ensure that the agricultural supply chain from preplanting to postharvesting generates enough food to achieve sustainable food security in developing countries. Drawing from complex adaptive systems (CAS) theory, we develop and test a model of how a prospective and challenging financing scheme navigates complex social and repayment systems to achieve sustainable SCF. The results of the study show that a challenging financing scheme must navigate complex social and repayment systems to achieve sustainable SCF, while a prospective financing scheme even though it shows a positive influence on sustainable SCF, its effect is higher when it is able to navigate these. The study hence concludes that for agricultural SCF schemes to lead to sustainable food security, they must be accessible and appropriate to the needs of the community, overcome default risk and cumbersome financial arrangements and be able to navigate the complex social and repayment systems. The study recommends that financing schemes should establish proximity to farming communities and engage farmers to determine appropriate funds for different stages among others.

本研究旨在探讨应克服哪些供应链融资(SCF)的先决条件,以确保从种植前到收获后的农业供应链能够产生足够的粮食,从而实现发展中国家的可持续粮食安全。借鉴复杂适应系统(CAS)理论,我们开发并测试了一个模型,说明一个具有前瞻性和挑战性的融资计划如何驾驭复杂的社会和还款系统,以实现可持续的供应链融资。研究结果表明,具有挑战性的融资计划必须驾驭复杂的社会和还款系统,才能实现可持续的可持续农业生产基金,而前瞻性融资计划即使对可持续农业生产基金有积极影响,但当它能够驾驭这些系统时,其影响会更大。因此,研究得出结论认为,农业 SCF 计划要实现可持续粮食安全,就必须便于使用,适合社区的需求,克服违约风险和繁琐的财务安排,并能够驾驭复杂的社会和还款系统。研究建议,融资计划应贴近农业社区,并让农民参与其中,以确定不同阶段的适当资金。

The emergence of high-value supply chains, led by supermarket buyers, has transformed traditional avenues for marketing fruits and vegetables in India. Our study explores the evolving relationships between Indian farmers and supermarket buyers in the horticultural market. The investigation centres on understanding farmer satisfaction in this dynamic marketing landscape and its impact on their commitment to supermarket buyers. We identified critical factors such as price offer, reduced marketing cost and convenience as pivotal to farmers' satisfaction using the survey administered to 242 respondents. Results highlight the positive impact of price offer, reduced marketing cost and convenience on farmers' satisfaction, while underscoring that market assurance hampers satisfaction levels among farmers. In practical terms, our findings emphasise the importance of addressing farmers' needs for a more fruitful and mutually enriching partnership with the supermarkets. The study contributes depth to discussions on the evolving face of horticulture, accentuating the impact of modern supply chains on farmer welfare and economic growth.

以超市买家为主导的高价值供应链的出现,改变了印度水果和蔬菜的传统销售渠道。我们的研究探讨了园艺市场中印度农民与超市买家之间不断发展的关系。调查的重点是了解农民在这一动态营销环境中的满意度及其对超市买家承诺的影响。通过对 242 名受访者进行调查,我们确定了价格优惠、营销成本降低和便利性等影响农民满意度的关键因素。调查结果表明,价格优惠、营销成本降低和便利性对农民满意度有积极影响,同时也强调了市场保证对农民满意度的影响。实际上,我们的研究结果强调了满足农民需求的重要性,以便与超市建立更富有成效、相互促进的伙伴关系。这项研究有助于深入探讨园艺业不断变化的面貌,强调现代供应链对农民福利和经济增长的影响。

Food safety is an issue of growing concern in many developing countries. Threats to food safety in Vietnam include contamination with toxic chemicals, microbiological hazards and adulterated food. To determine Vietnamese consumers' willingness to pay for food safety of pork and vegetables, a discrete choice experiment was employed in the cities of Hanoi and Haiphong. Principal factor analysis and mixed logit models reveal that urban consumers are, on average, willing to pay considerable price premiums for food safety attributes. On average, consumers are willing to pay a price premium of 244% for vegetables produced with the safe application of pesticides, 70% premium for pork processed in certified abattoirs that assure pork safety and 67% price premium for pork if the convenience attribute is satisfied. Regarding vegetables, there is considerable heterogeneity in the extent to which consumers are willing to pay for growth-hormone-free vegetables, depending on their education, and in perceptions towards food safety risks resulting from chemical hazards and foodborne illness in Vietnam. For pork, if consumers believe that contaminated food could cause life-threatening risks for people, they are willing to pay up to 102% more than the current market price for hormone-free and drug-free pork. The factor representing consumers' trust in food safety influences their WTP for traceability and clean water attributes. Moreover, consumer's self-health evaluation influenced their WTP for pork traceability. Almost all consumers prefer the convenience of being able to purchase vegetables and pork nearby.

食品安全是许多发展中国家日益关注的问题。越南食品安全面临的威胁包括有毒化学品污染、微生物危害和食品掺假。为了确定越南消费者是否愿意为猪肉和蔬菜的食品安全买单,我们在河内和海防两市进行了离散选择实验。主因子分析和混合对数模型显示,城市消费者平均愿意为食品安全属性支付相当高的溢价。平均而言,消费者愿意为安全施用农药生产的蔬菜支付 244% 的溢价,愿意为经认证的屠宰场加工的猪肉支付 70% 的溢价,愿意为满足便利属性的猪肉支付 67% 的溢价。在蔬菜方面,消费者愿意为无生长激素蔬菜付费的程度存在很大差异,这取决于他们的教育程度,以及对越南化学危害和食源性疾病导致的食品安全风险的看法。就猪肉而言,如果消费者认为受污染的食品会给人们带来生命危险,那么他们愿意为无激素和无药物的猪肉支付比目前市场价格高出102%的价格。代表消费者对食品安全信任的因素影响了他们对可追溯性和清洁水属性的 WTP。此外,消费者的自我健康评价也影响了他们对猪肉可追溯性的购买意愿。几乎所有的消费者都喜欢就近购买蔬菜和猪肉的便利性。

Is there a link between meat production and infectious diseases? Researchers, policymakers and pundits argue that the growth of demand for meat in Asia can increase the risk of zoonotic diseases, pathogens that originate in animals and can be transmitted to humans. Using original data on zoonotic disease outbreaks in 22 Asian countries between 1996 and 2019, this study examines the impact of beef, chicken and pork production on zoonotic outbreaks—focussing on all diseases and disaggregated subcategories. Because such outbreaks lead to culling animals, data on inorganic chemical fertiliser use are used to identify the plausibly exogenous relationship flowing from meat production to outbreaks. Results indicate that in these countries, intensive meat production may have contributed to a 16%–300% rise (for a one-million-tonne increase in output) in zoonotic outbreak incidence. Findings also suggest this relationship is primarily driven by flu pathogens' higher sensitivity to meat production, with a one-million-tonne increase in output being associated with a 48%–530% rise in the number of predicted flu outbreaks. These results are consistent across numerous sensitivity analyses accounting for modelling, operationalisation, and data selection choices.

肉类生产与传染病之间有联系吗?研究人员、政策制定者和专家学者认为,亚洲对肉类需求的增长会增加人畜共患病的风险,这些疾病是源于动物并可传染给人类的病原体。本研究利用 1996 年至 2019 年期间 22 个亚洲国家爆发人畜共患病的原始数据,研究了牛肉、鸡肉和猪肉生产对人畜共患病爆发的影响,重点关注所有疾病和分类子类别。由于此类疫情爆发会导致宰杀动物,因此使用无机化学肥料使用数据来确定肉类生产与疫情爆发之间看似外生的关系。结果表明,在这些国家,密集型肉类生产可能导致人畜共患病爆发率上升 16%-300%(产量增加 100 万吨)。研究结果还表明,这种关系主要是由于流感病原体对肉类生产的敏感性较高,产量增加 100 万吨,预计流感爆发的次数就会增加 48%-530%。在对建模、操作和数据选择进行多次敏感性分析后,这些结果是一致的。

How to reduce household food waste during and after the COVID-19 lockdown? Evidence from a structural model 如何在 COVID-19 封锁期间和之后减少家庭食物浪费?来自结构模型的证据

The COVID-19 lockdown precipitated a fundamental shift in consumer food-related behaviours. Owing to adherence to stay-at-home directives and concerns over potential exposure to the coronavirus, consumers engaged in less frequent in-person shopping, opting for larger quantities of food purchased per trip, a trend with the potential to exacerbate food wastage patterns among bulk food purchasers. Nevertheless, recent empirical data obtained from the United Kingdom have revealed a 34% reduction in household food waste during the nationwide lockdown in April 2020. To gain deeper insights into the underlying mechanisms governing household food waste behaviours, we employ an infinite horizon dynamic stochastic model that operates on a daily cycle, focusing specifically on household food inventory management. Our analysis demonstrates that absent any improvements in food management practices, panic-stricken consumers who stockpiled food at home during the early phase of the pandemic generated significantly higher levels of food waste. Conversely, consumers who embraced effective food management techniques and transitioned to online grocery shopping managed to reduce household food waste by about 50% during the pandemic. Additionally, we conduct simulations to envision potential post-pandemic scenarios and conclude the study with a set of recommendations aimed at curbing household food waste in the aftermath of the pandemic.

COVID-19 封锁促使消费者与食品有关的行为发生了根本性转变。由于遵守足不出户的指令以及对可能接触冠状病毒的担忧,消费者减少了亲自购物的频率,选择每次购买更多数量的食品,这种趋势有可能加剧大宗食品购买者的食品浪费模式。尽管如此,最近从英国获得的经验数据显示,在 2020 年 4 月全国封锁期间,家庭食物浪费减少了 34%。为了更深入地了解家庭食物浪费行为的内在机制,我们采用了一个以每天为周期的无限远动态随机模型,特别关注家庭食物库存管理。我们的分析表明,在食品管理方法没有任何改进的情况下,在大流行病早期阶段在家中囤积食品的恐慌性消费者所产生的食品浪费水平要高得多。相反,那些采用有效的食品管理技术并过渡到网上购物的消费者在大流行期间成功地将家庭食品浪费减少了约 50%。此外,我们还进行了模拟,以设想大流行后可能出现的情况,并在研究结束时提出了一系列旨在遏制大流行后家庭食物浪费的建议。

Looking at the role of solar photovoltaics in the energy transition is reminiscent of the paradox arising from the clash of an irresistible force and an immovable object. In this note, it will be argued that the irresistible force of low-cost solar generation will win out over the apparently immovable obstacles.

Fiordland National Park is a UNESCO site located in the remote, southwest of New Zealand's South Island, which attracts hundreds of thousands of visitors every year. One of its leading attractions is Milford Sound. An oil spill in this area could not only impact the industries that operate in Milford Sound but also impact all of the park. To improve the knowledge base about this area in regard to oil spills and policies regarding ship visitation, this study aimed to estimate the costs of clean-up, impacts to fisheries, tourism, recreation and the wildlife/environment under three oil spill scenarios in Milford Sound. Minimum costs are estimated at NZD 140–154 million. These results demonstrate the need for proper planning and response measures, and appropriate domestic and international policies to help minimise the potential damages that may occur in the event of an oil spill in a remote and pristine area of New Zealand.

峡湾国家公园(Fiordland National Park)位于新西兰南岛偏远的西南部,是联合国教科文组织(UNESCO)认定的旅游景点,每年吸引着成千上万的游客。其主要景点之一是米尔福德峡湾。该地区的漏油事件不仅会影响在米尔福德峡湾开展业务的行业,还会对整个公园造成影响。为了提高人们对该地区漏油事故的认识,并完善有关船舶游览的政策,本研究旨在估算米尔福德峡湾三种漏油情况下的清理成本,以及对渔业、旅游业、娱乐业和野生动物/环境的影响。最低成本估计为 1.4 亿至 1.54 亿新西兰元。这些结果表明,有必要采取适当的规划和应对措施,并制定适当的国内和国际政策,以帮助最大限度地减少在新西兰这个偏远的原始地区发生漏油事件时可能造成的损失。

This paper investigates the volatility connectedness and dynamic time–frequency relationship between Bitcoin (BTC) and 15 major agricultural commodity markets during the COVID-19 and 2022 Russia–Ukraine war periods. We employ the TVP-VAR-based extended joint connectedness method, minimum connectedness investment portfolio, and wavelet coherence (WC) method. The results indicate that the sudden outbreaks of the two crises brought about increased volatility connectedness between BTC and agricultural commodity markets. Throughout the entire sample period, BTC remained a net transmitter of volatility. Moreover, in terms of the total connectedness index (TCI), the overall volatility correlation surged rapidly after the outbreak of COVID-19 and the 2022 Russia–Ukraine war. The portfolio results demonstrated that BTC exhibited a low correlation with the agricultural commodity markets, suggesting diversification potential. Additionally, only Feeder Cattle served as an effective hedging asset for BTC throughout all periods. The WC analysis confirmed that during the COVID-19 period and the 2022 Russia–Ukraine war, most of the linkages were primarily concentrated at medium- to long-term frequencies. Our analysis will contribute to a deeper understanding of the interconnection between these markets, enabling market participants to consider risk mitigation measures and support portfolio diversification when formulating policies and regulations involving relevant markets in the future.

本文研究了 COVID-19 和 2022 年俄乌战争期间比特币(BTC)与 15 个主要农产品市场之间的波动连通性和动态时频关系。我们采用了基于 TVP-VAR 的扩展联合连通性方法、最小连通性投资组合和小波一致性(WC)方法。结果表明,两次危机的突然爆发增加了 BTC 与农产品市场之间的波动关联性。在整个样本期间,BTC 仍然是波动的净传递者。此外,从总关联指数(TCI)来看,在 COVID-19 和 2022 年俄乌战争爆发后,整体波动相关性迅速飙升。投资组合结果表明,BTC 与农产品市场的相关性较低,表明具有多样化潜力。此外,在所有时期,只有饲料牛是 BTC 的有效对冲资产。WC 分析证实,在 COVID-19 期间和 2022 年俄乌战争期间,大多数联系主要集中在中长期频率上。我们的分析将有助于加深对这些市场之间相互联系的理解,使市场参与者在未来制定涉及相关市场的政策和法规时,能够考虑风险缓解措施并支持投资组合多样化。

Generative artificial intelligence tools have been shown to substantially increase productivity in a range of different contexts. I discuss the potential and limitations of the current models, and the evidence on how economic researchers can best make use of generative artificial intelligence in their work. To illustrate these points, I show how the data analysis tools of ChatGPT can be used to address a specific question: the accuracy of agricultural forecasts—and discuss the strengths and weaknesses of artificial intelligence in data cleaning, data analysis and producing graphs and illustrations.

生成式人工智能工具已被证明能在一系列不同情况下大幅提高生产率。我将讨论当前模型的潜力和局限性,以及经济研究人员如何在工作中更好地利用生成式人工智能的证据。为了说明这些观点,我展示了如何利用 ChatGPT 的数据分析工具来解决一个具体问题:农业预测的准确性,并讨论了人工智能在数据清理、数据分析以及制作图表和插图方面的优缺点。

The impact of repayment obligations arising as a by-product of input use on partial inefficiency: Evidence from Western Australian farm businesses 作为投入品使用的副产品而产生的还款义务对部分低效率的影响:来自西澳大利亚农场企业的证据

Farm businesses often use debt to finance the purchase inputs and meet operational costs. Selected studies have investigated the impact of debt use on farm performance as measured using technical efficiency. However, no prior studies in agriculture have considered treating the debt repayment obligation created as a by-product of production when benchmarking farm performance. This study employs nonparametric directional distance function models to quantify the impact of debt repayment as a by-product of input use purchased on credit on farm-level partial inefficiency using a panel data of 54 mixed enterprise broadacre farms in Western Australia from 2002 to 2011. The study finds that omitting repayment obligations created in the production process in analysis results in underestimating partial inefficiency scores. Farm size, production diversification and rainfall zone are significant drivers of partial inefficiency. The implication of the study's findings is that failure to account for repayment obligations created in the production process may result in erroneous policy suggestions that undermine the efforts of farm businesses to minimise or avoid financial stress.

农场企业经常利用债务为购买投入品和支付运营成本提供资金。一些研究调查了债务使用对使用技术效率衡量的农场绩效的影响。然而,之前的农业研究在设定农场绩效基准时,并未考虑将债务偿还义务作为生产的副产品来处理。本研究采用非参数定向距离函数模型,利用 2002 年至 2011 年西澳大利亚州 54 个混合企业宽耕地农场的面板数据,量化了作为赊购投入使用副产品的债务偿还对农场层面部分低效的影响。研究发现,在分析中忽略生产过程中产生的还款义务会导致部分无效率得分被低估。农场规模、生产多样化和降雨区是部分无效率的重要驱动因素。研究结果的意义在于,如果不考虑生产过程中产生的还款义务,可能会导致错误的政策建议,从而损害农场企业为最大限度地减少或避免财务压力所做的努力。
