The proposed reductions in farm input uses foreseen in the European Green Deal may penalize European farm production while increasing environmental leakages to foreign countries where production may expand. These expected impacts have led to calls for a more restrictive trade policy based on mirror clauses. This paper considers as a case study a potential ban on glyphosate in vegetable and fruits production. We develop an original computable general equilibrium model with endogenous adoption of new European production standards by foreign producers on currently latent markets. We find in our case study that adding mirror clauses to the Green Deal marginally improves European farm income and the global environmental footprint of food. We find that foreign producers as a whole can gain from these clauses and not lose as in a standard analysis. European households support these clauses by paying higher food bills while consuming vegetables and fruits produced without glyphosate.

欧洲绿色交易》中预计的减少农业投入用途的建议可能会惩罚欧洲的农业生产,同时增加对生产可能扩大的外国的环境泄漏。这些预期影响导致人们呼吁根据镜像条款制定更具限制性的贸易政策。本文以可能禁止在蔬菜和水果生产中使用草甘膦为例进行研究。我们建立了一个独创的可计算一般均衡模型,其中包含了外国生产商在当前潜在市场上采用新欧洲生产标准的内生因素。我们在案例研究中发现,在 "绿色协议 "中增加镜像条款可略微提高欧洲农业收入和全球食品环境足迹。我们发现,外国生产商作为一个整体可以从这些条款中获益,而不是像标准分析那样遭受损失。欧洲家庭通过支付更高的食品账单来支持这些条款,同时消费不使用草甘膦生产的蔬菜和水果。

This study discusses the modernization of smallholder agriculture in China, where most farms are small, and farms' parcels are fragmented. The study puts forward a framework of agricultural modernization by vertical division of labor and specialized production in agriculture. We posit that hiring machinery services could be a pathway to connect smallholders with modern agriculture and achieve food security in China. Using household-level data from China, this study examines how hiring machinery services affects farm productivity and rural households' welfare. Findings show that mechanization services increased rural Chinese families' food security and agricultural productivity. Hiring machinery services improves smallholders' income by influencing the input efficiency of maize production and increasing participation in off-farm work. Our findings highlight the importance of technology to improve smallholder agriculture and food security, not only in China but also in other South and Southeast Asian countries.

本研究探讨了中国小农农业的现代化问题,中国的农场大多规模较小,农场的地块也比较分散。研究提出了一个通过农业垂直分工和专业化生产实现农业现代化的框架。我们认为,在中国,雇佣机械服务可能是连接小农户与现代农业、实现粮食安全的一条途径。本研究利用中国家庭层面的数据,探讨了雇佣机械服务如何影响农业生产率和农村家庭福利。研究结果表明,机械化服务提高了中国农村家庭的粮食安全和农业生产率。通过影响玉米生产的投入效率和增加非农工作的参与度,雇佣机械服务提高了小农户的收入。我们的研究结果凸显了技术对改善小农农业和粮食安全的重要性,不仅在中国如此,在其他南亚和东南亚国家也是如此。

Agricultural and Applied Economics departments in the United States have evolved to serve traditional and new stakeholders under the three-legged land grant mission: extension, research, and teaching. Substantial shifts in the focus of faculty, sometimes matching demand from stakeholders and sometimes not, raise fundamental questions about their strategic direction. We argue agricultural and applied economics has a mission to solve problems, current and future, by working with physical sciences; specifically, the study of economic problems of the food supply chain and bioeconomy. By focusing on this mission, agricultural and applied economics will provide more value-added to society and may even improve economics while doing so.

美国的农业与应用经济系在三足鼎立的土地赠与使命(推广、研究和教学)下不断发展,为传统的和新的利益相关者提供服务。教职员工工作重点的重大转变,有时与利益相关者的需求相吻合,有时则不然,这就对其战略方向提出了根本性的问题。我们认为,农业与应用经济学的使命是通过与物理科学的合作来解决当前和未来的问题,特别是研究食品供应链和生物经济的经济问题。通过专注于这一使命,农业与应用经济学将为社会提供更多附加值,甚至可能在这样做的同时改善经济。

In this paper, we use transaction data from a large grocery store retailer to describe changes in grocery shopping behavior associated with the progression of the COVID-19 pandemic before and after the vaccines were developed. We find that in general, households increased their spending and decreased their number of transactions early in the pandemic. Further, most households increased their reliance on online shopping during the pandemic and this shift persisted into the post-vaccine period. We find somewhat mixed results on how overall healthfulness of grocery store purchases changed during the pandemic, and we find that changes in healthfulness vary with market and household demographics. Perhaps most interestingly, we find that changes in a store's spending and transactions, along with the healthfulness of these purchases, vary significantly with the racial composition of a store's market and that these differential changes persisted after vaccines were available.

在本文中,我们利用一家大型食品杂货店零售商提供的交易数据,描述了与 COVID-19 疫苗研发前后大流行的进展相关的食品杂货店购物行为的变化。我们发现,总体而言,在大流行初期,家庭增加了支出,减少了交易次数。此外,大多数家庭在大流行期间增加了对网上购物的依赖,这种转变一直持续到疫苗接种后。我们发现,在大流行期间,杂货店购物的整体健康程度发生了怎样的变化,结果不一。也许最有趣的是,我们发现商店消费和交易的变化,以及这些购买的健康性,与商店市场的种族构成有很大的不同,而且这些不同的变化在疫苗上市后依然存在。

This study examined the impact of the mad cow (BSE) and bird flu (HPAI) outbreaks on the demand for beef, pork, and broiler meat in the United States from 1997 to 2022. Using time-varying elasticities obtained from the Rotterdam model extended to include animal disease outbreaks, we found that the BSE outbreaks significantly reduced beef consumption. These reactions were indeed time-varying, ranging from 1.312% in 2003 to 1.212% in 2005. HPAI outbreaks had a delayed reaction, with a rebound in broiler meat consumption in the quarter following the start of the outbreak. In general, the magnitude of these reactions was proportional to the severity of an outbreak.

本研究探讨了 1997 年至 2022 年期间疯牛病(BSE)和禽流感(HPAI)疫情爆发对美国牛肉、猪肉和肉鸡肉类需求的影响。利用从鹿特丹模型中获得的时变弹性,我们发现疯牛病疫情的爆发大大降低了牛肉的消费量。这些反应确实是时变的,从 2003 年的 1.312% 到 2005 年的 1.212%。高致病性禽流感疫情的反应是延迟的,在疫情开始后的一个季度,肉鸡肉类消费出现反弹。一般来说,这些反应的程度与疫情的严重程度成正比。

The World Trade Organization (WTO) protects geographical indication (GI) wines such as Bordeaux and Chianti. However, there is scant empirical evidence on the effectiveness of this protection. Our triple difference panel data analysis of EU wine exports from 1995 to 2019 finds a significant effect. When countries join the WTO, their import of GI wines increases by about 25% more than non-GI wines, compared to non-joiners. Our findings suggest that specific trade provisions matter and that the EU policy of also including wine GIs in bilateral agreements is an attempt to further improve enforcement of GI protection in third countries.

世界贸易组织(WTO)保护地理标志葡萄酒,如波尔多葡萄酒和基安蒂葡萄酒。然而,有关这种保护有效性的经验证据却很少。我们对 1995 年至 2019 年欧盟葡萄酒出口的三重差异面板数据分析发现了显著的影响。与未加入 WTO 的国家相比,加入 WTO 的国家的地理标志葡萄酒进口量比非地理标志葡萄酒增加了约 25%。我们的研究结果表明,具体的贸易条款很重要,欧盟将葡萄酒地理标志纳入双边协议的政策是为了进一步改善第三国对地理标志保护的执行情况。

Through the perspectives of impact investors, and the nutrition community, this paper explores whether impact investment in food-related small and medium enterprises (SMEs) creates a viable path to improved nutrition in Sub-Saharan Africa. From the nutrition perspective, investment in food SMEs could help address coexisting multiple forms of malnutrition by shifting nutritional quality of available foods. From the investor perspective, attractiveness of investment in food SMEs depends on financial risks, how costs are passed on to consumers, and probability of impact. Clear nutritional objectives and investment criteria are needed, as well as research to maximize the potential of this innovative approach.

本文从社会企业投资者和营养界的角度出发,探讨在撒哈拉以南非洲地区,对与食品相关的中小企业(SMEs)进行社会企业投资是否是改善营养状况的可行途径。从营养学的角度来看,对食品中小企业的投资可以通过改变现有食品的营养质量,帮助解决并存的多种形式的营养不良问题。从投资者的角度来看,对中小型食品企业投资的吸引力取决于财务风险、如何将成本转嫁给消费者以及产生影响的可能性。需要制定明确的营养目标和投资标准,并开展研究,以最大限度地发挥这种创新方法的潜力。

Starting in 2006, China launched a project to carry out Basic Farmland Construction in 116 representative counties. The objective of this project was to enhance agricultural productivity. China invested 30 billion yuan in this project from 2006 to 2013. Using a difference-in-differences approach, this study estimates that Basic Farmland Construction increased per capita agricultural output by 6.3%, crop sown area by 5%, and agricultural mechanization by 7.3%. The total benefits of the project far exceeded the total investments. By incorporating with rainfall shocks, this study finds that the project could mitigate most of the damage from droughts and floods.

从 2006 年开始,中国在 116 个有代表性的县启动了基本农田建设项目。该项目的目标是提高农业生产力。从 2006 年到 2013 年,中国在该项目上投入了 300 亿元。本研究采用差分法估算,基本农田建设使人均农业产值提高了 6.3%,农作物播种面积提高了 5%,农业机械化提高了 7.3%。项目总收益远远超过总投资。通过结合降雨冲击,本研究发现该项目可减轻干旱和洪水造成的大部分损失。

We use a panel smooth transition regression model to investigate the influence of Conservation Reserve Program (CRP) rental rates on land enrollment under different crop price regimes. We employ a flexible estimation technique, allowing the CRP rental rate incentives to vary with crop prices, and construct a Hausman-type instrumental variable to address endogeneity. Simulations are conducted to assess the impact of varying crop prices on CRP acreage and its associated environmental effects. Results reveal a nonlinear relationship between rental rates and enrollment, with the impact diminishing as crop prices increase. A 10% rise in CRP rental rates corresponds to a 5.1% expansion in enrollment, reducing to 4.2% when crop prices reach a specific threshold. High crop prices lead to fewer acres enrolled, decreased carbon sequestration, increased phosphorus and nitrogen runoff, and increased sediment loss. Our findings highlight the importance of considering price fluctuations in conservation planning as it has significant implications for environmental conservation policies and programs.

我们使用面板平稳过渡回归模型来研究在不同作物价格体系下,保护储备计划(CRP)租金对土地注册的影响。我们采用了灵活的估算技术,允许 CRP 租金激励随作物价格的变化而变化,并构建了 Hausman 型工具变量来解决内生性问题。我们进行了模拟,以评估不同作物价格对 CRP 种植面积及其相关环境效应的影响。结果显示,租金与注册人数之间存在非线性关系,随着农作物价格的上涨,其影响逐渐减弱。CRP 租金上涨 10%,注册人数增加 5.1%,当作物价格达到特定临界值时,注册人数减少到 4.2%。高农作物价格会导致种植面积减少、碳固存减少、磷和氮径流增加以及沉积物流失增加。我们的研究结果凸显了在保护规划中考虑价格波动的重要性,因为它对环境保护政策和计划具有重大影响。

The USDA Food Security Survey Module (FSSM) is the gold standard for measuring food security; however, research suggests that college students may respond to FSSM items differently than the general population. Students may have a varied portfolio of food and financial resources (thus, complicating interpretations of “money”) to acquire food. We conducted a randomized control trial to test whether a preamble to address this issue improves model fit. Results indicated the preamble did not improve model fit, and students' responses deviated from expected patterns. More research could help understand these deviations and their implications for measuring FI on college campuses.

美国农业部食品安全调查模块(FSSM)是衡量食品安全的黄金标准;然而,研究表明,大学生对 FSSM 项目的反应可能与普通人不同。学生可能拥有不同的食物和经济资源组合(因此,对 "金钱 "的解释也会变得复杂)来获取食物。我们进行了一项随机对照试验,以检验针对这一问题的前言是否能提高模型拟合度。结果表明,前言并没有改善模型拟合度,学生的回答偏离了预期模式。更多的研究将有助于了解这些偏差及其对测量大学校园中 FI 的影响。
