Greater women's bargaining power and decision-making within a household have been shown to increase investments in human capital. This study links women's participation in decision-making in dairy production with household investment in girls and boys in health, nutrition, and education. We survey households in the urbanizing region of Bangalore, India. We utilize a multinomial treatment effects model to analyze the individual and household factors that are associated with women's participation in sole or joint decision-making. We then assess how the type of decision-making influences a household's investments. The results first show that female decision-making households are more disadvantaged on average than other types of decision-making households. Second, we observe that female decision-makers for dairy production are more likely to have more children and earn a higher income than their husbands. Third, the main findings show that households in which women engage in joint decision-making have higher levels of investment across all categories for girls. Conversely, investments decrease in education and nutrition for both girls and boys when the wife is the sole decision-maker. Lastly, investments are enhanced further for girls when households can sell milk at a higher price.

事实证明,妇女在家庭中更大的议价权和决策权可增加对人力资本的投资。本研究将妇女参与乳制品生产决策与家庭对女孩和男孩在健康、营养和教育方面的投资联系起来。我们对印度班加罗尔城市化地区的家庭进行了调查。我们利用多项式处理效应模型来分析与妇女参与单独或共同决策相关的个人和家庭因素。然后,我们评估了决策类型对家庭投资的影响。结果首先表明,与其他类型的决策家庭相比,女性决策家庭平均处于更不利的地位。其次,我们观察到,乳制品生产的女性决策者更有可能比她们的丈夫生育更多的孩子,收入也更高。第三,主要研究结果表明,在妇女参与共同决策的家庭中,女孩在所有类别中的投资水平都较高。相反,如果妻子是唯一的决策者,女孩和男孩在教育和营养方面的投资都会减少。最后,当家庭能够以更高的价格出售牛奶时,女孩的投资会进一步增加。

This study developed a theoretical model to explain the consolidation of farmland and specialization in agriculture. In the model, farmers are assumed to be endowed with knowledge regarding the production of each crop, which evolves through learning. Knowledge across crops is substitutable to various degrees. The farm size distribution and specialization are shown to be equilibrium outcomes determined by the distribution of knowledge. A simulation example based on farm-level acreage data from California is presented to show the relevance of learning mechanisms and test model implications.

本研究建立了一个理论模型来解释耕地整合和农业专业化。在该模型中,假定农民拥有关于每种作物生产的知识,这些知识通过学习不断发展。不同作物的知识具有不同程度的可替代性。农场规模分布和专业化被证明是由知识分布决定的均衡结果。本文以加利福尼亚州农场一级的种植面积数据为基础,提出了一个模拟实例,以说明学习机制的相关性并检验模型的含义。

Our objective in this paper is to examine the growth of the price of farm milk quotas in Canada, to shed light on their patterns of growth within the last 15 years. Our quota price model is based on the Gordon growth model, supplemented by some important characteristics of the milk quota market. Our explanatory variables include the quota rental price, interest rate, and expectations of both price and quantity growth, all for the province of Alberta over the 2009–2023 time period. Our economic model of quota prices performs well by giving results with the predicted signs for all variables in our model and high levels of statistical significance except for expectations of quantity allocations when entered separately. The model has two variants, one with the expectation of growth in quota rents and the other with the expectation of growth in the quota asset price. Econometric issues related to time series problems are dealt with. The model allows calculation of policy risk, which shows an interesting pattern over this time period.

本文旨在研究加拿大农场牛奶配额价格的增长情况,以揭示其在过去 15 年中的增长模式。我们的配额价格模型以戈登增长模型为基础,辅以牛奶配额市场的一些重要特征。我们的解释变量包括阿尔伯塔省 2009-2023 年期间的配额租赁价格、利率以及价格和数量增长预期。我们的配额价格经济模型表现出色,模型中的所有变量都出现了预测的符号,而且除了单独输入数量分配预期外,其他变量都具有较高的统计显著性。该模型有两个变体,一个是配额租金增长预期,另一个是配额资产价格增长预期。处理了与时间序列问题有关的计量经济学问题。该模型可以计算政策风险,在这一时期显示出一种有趣的模式。

In this paper, we investigate the impacts of climate extremes on the production and trade of apples. Apple production being notoriously sensitive to climate shocks, we show that March and April temperatures and precipitations beyond estimated thresholds cause large yield reductions in Quebec and Ontario. In years when climate shocks are large and highly correlated across space, large variations in national production cause major variations in trade flows. Hence, we exploit the theoretical foundations of a sectoral structural gravity model to implement counterfactual trade experiments about harvest shocks in Canada and the United States. We report changes in tariffs, imports, exports, farmgate prices, and in consumer welfare. The shocks greatly impact trade between North American countries but have little impact on other countries except for Chile and New Zealand which see their exports grow.

在本文中,我们研究了极端气候对苹果生产和贸易的影响。苹果生产对气候冲击的敏感度是众所周知的,我们的研究表明,3 月和 4 月的气温和降水量超过估计的临界值会导致魁北克和安大略的苹果大幅减产。在气候冲击较大且跨空间高度相关的年份,全国产量的巨大变化会导致贸易流量的重大变化。因此,我们利用部门结构重力模型的理论基础,对加拿大和美国的收成冲击进行了反事实贸易实验。我们报告了关税、进口、出口、农场交货价格和消费者福利的变化。冲击极大地影响了北美国家之间的贸易,但对其他国家的影响很小,只有智利和新西兰的出口出现增长。

Sustainability labeling has been increasingly integrated into many food product labels in response to consumer interest in purchasing sustainably produced food. While a product label may contain the phrase “sustainably produced”, little additional information is available to consumers regarding how sustainability has been enhanced, or the dimensions of sustainability encompassed by the label. Using data from a survey of 1416 Canadian consumers, we examine consumer perceptions of sustainability and preferences for broad versus narrow sustainability claims across several contexts, including the dimensions of sustainability and the scope of a sustainability standard with respect to compliance criteria, product coverage, and geographical coverage. We find low levels of consumer knowledge and understanding of sustainability labeling, heterogeneity with respect to which dimension of sustainability appeals to different types of consumers, and a general preference for broad over narrowly defined sustainability labels, particularly with respect to the scope of criteria encompassed by the label. Our findings suggest some confusion as to what constitutes sustainability in the context of agri-food, but that broader, more encompassing labels are likely to gain more traction with consumers.

为了满足消费者对购买可持续生产食品的兴趣,可持续性标签越来越多地被纳入许多食品标签中。虽然产品标签上可能包含 "可持续生产 "的字样,但消费者几乎无法获得更多有关如何提高可持续性或标签所包含的可持续性维度的信息。利用对 1416 名加拿大消费者的调查数据,我们研究了消费者对可持续性的看法,以及在几种情况下对广义和狭义可持续性声明的偏好,包括可持续性的维度和可持续性标准在合规标准、产品覆盖范围和地理覆盖范围方面的范围。我们发现,消费者对可持续发展标签的了解和理解程度较低,不同类型的消费者对可持续发展的哪个维度具有吸引力存在差异,而且消费者普遍倾向于广义的可持续发展标签,而不是狭义的可持续发展标签,特别是在标签所涵盖的标准范围方面。我们的研究结果表明,在农业食品方面,人们对什么是可持续性存在一些困惑,但更广泛、更全面的标签可能会获得消费者更多的青睐。

Explaining consumer willingness to pay for country-of-origin labeling with ethnocentrism, country image, and product image: Examples from China's beef market 用民族中心主义、国家形象和产品形象解释消费者为原产国标签付费的意愿:以中国牛肉市场为例

Chinese beef imports have been increasing in recent years. At the same time, Chinese public sentiment toward foreign countries, including those who export beef to China, has been changing. Therefore, this research uses a discrete choice experiment (DCE) to investigate the role of ethnocentrism, country image, and product image on consumer willingness to pay for country-of-origin labeled beef. Results indicate, on average, Chinese consumers prefer domestic beef most, and value beef from Australia and the US somewhat similarly. Their willingness to pay varies based on their perceived image of the country that the beef originates from and based on their perception of the safety of the beef, that is, product image. The more ethnocentric consumers are, the more they prefer domestic beef and discount foreign beef. Importantly, the effects of ethnocentrism, country image, and product image are stronger on the willingness to pay for domestic beef than for imported beef. More generally, findings indicate that controlling for ethnocentrism, country image, and product image contributes to understanding consumer willingness to pay for products originating from foreign countries. Overall, findings suggest that stronger ethnocentric tendencies lead to lower willingness to pay for imported beef (with some exceptions), and positive country image and product image increase the willingness to pay for imported beef. Thus, it is important to consider these constructs when estimating consumer willingness to pay for imported products, especially for countries where public sentiment toward exporting countries may be prone to change in a dynamic global environment.

近年来,中国牛肉进口量不断增加。与此同时,中国公众对外国(包括对华出口牛肉的国家)的情感也在发生变化。因此,本研究采用离散选择实验(DCE)来研究民族中心主义、国家形象和产品形象对消费者购买原产地标记牛肉的支付意愿的影响。研究结果表明,平均而言,中国消费者最喜欢国产牛肉,对澳大利亚和美国牛肉的评价也差不多。他们的支付意愿因对牛肉原产国形象的感知和对牛肉安全性的感知(即产品形象)而异。消费者的民族中心主义程度越高,他们就越偏爱国产牛肉,而对外国牛肉不屑一顾。重要的是,与进口牛肉相比,民族中心主义、国家形象和产品形象对国产牛肉支付意愿的影响更大。更广泛地说,研究结果表明,控制民族中心主义、国家形象和产品形象有助于了解消费者对原产于外国的产品的支付意愿。总体而言,研究结果表明,较强的民族中心主义倾向会导致消费者对进口牛肉的支付意愿降低(但也有例外),而积极的国家形象和产品形象则会提高消费者对进口牛肉的支付意愿。因此,在估算消费者对进口产品的支付意愿时,考虑这些因素非常重要,尤其是对于公众对出口国的情绪在动态的全球环境中可能容易发生变化的国家。

Increasing frequency of extreme weather events threatens the livelihoods of low-income farm households due to the heavy dependence on rain-fed agriculture coupled with the under-developed formal markets for risk management products. Thus, crop diversification is one of the widely used ex ante adaptation strategies to hedge against weather risk exposure. In this study, we use survey data from the northern Savanna zone of Ghana merged with historical weather data to shed light on the heterogeneous impact of crop diversification on farm net returns and risk exposure. We employ the dose response function and instrumental variable techniques to address potential endogeneity concerns. Overall, our findings show that crop diversification is a welfare-enhancing strategy that significantly increases farm net returns, lowers the probability of crop failure, and thus decreases downside risk exposure. Notably, our dose-response function analysis demonstrates that the positive benefits of crop diversification are particularly pronounced at lower intensities, reaching an optimal threshold. Beyond this point, the incremental advantages tend to diminish, suggesting the importance of carefully considering the optimal level of diversification for maximum benefits. The results further underscore the significant impact of both access to agricultural extension services and fertilizer usage on the adoption of crop diversification.

由于严重依赖雨水灌溉的农业,加上风险管理产品的正规市场不发达,极端天气事件日益频繁,威胁着低收入农户的生计。因此,作物多样化是广泛使用的事前适应策略之一,以规避天气风险。在本研究中,我们利用加纳北部热带草原区的调查数据与历史天气数据相结合,揭示了作物多样化对农场净收益和风险敞口的不同影响。我们采用剂量反应函数和工具变量技术来解决潜在的内生性问题。总体而言,我们的研究结果表明,作物多样化是一种提高福利的策略,它能显著提高农场净收益,降低作物歉收的概率,从而降低下行风险敞口。值得注意的是,我们的剂量-反应函数分析表明,作物多样化的积极效益在较低的强度下尤为明显,达到最佳阈值。超过这个临界点,增量优势就会逐渐减弱,这表明必须仔细考虑多样化的最佳水平,以获得最大效益。研究结果进一步强调了获得农业推广服务和使用化肥对采用作物多样化的重要影响。

In the United States, truck rates for perishable food, the per-mile rate charged for trucking services to move perishable food from farms to stores, rose substantially in the post-COVID-19 pandemic era. We argue that rising truck rates is a signal of a broader shortage of truckers, but the connection between labor shortages, rising truck rates, and a lack of trucking services has yet to be established empirically. In this paper, we develop an empirical examination based on an equilibrium job search, matching, and bargaining framework in which we estimate the role of labor shortages in accelerating driver-wage growth, and truck rates for agricultural products. We estimate the model by combining US Bureau of Census Current Population Survey data on truck driver wages with USDA-Agricultural Marketing Service Service data on truck rates to establish the linkage between trucker supply and the demand for trucking services. We find that the COVID-19 pandemic was responsible for a rise in for-hire trucker wages of some 38%$38%$, a rise in average truck rates of nearly 50%$50%$ and that the gap between trucker-job openings and successful matches explains a significant, but small, rise in truck rates.

在美国,易腐食品的卡车费率,即把易腐食品从农场运到商店的卡车运输服务的每英里费率,在后 COVID-19 大流行时代大幅上升。我们认为,卡车运价上涨是卡车司机普遍短缺的信号,但劳动力短缺、卡车运价上涨和卡车运输服务缺乏之间的联系尚未通过实证研究得到证实。在本文中,我们基于均衡求职、匹配和讨价还价框架进行了实证研究,估计了劳动力短缺在加速司机工资增长和农产品卡车运价上涨中的作用。我们结合美国人口普查局当前人口调查的卡车司机工资数据和美国农业部农业营销服务局的卡车运价数据对模型进行了估计,以建立卡车司机供应与卡车运输服务需求之间的联系。我们发现,COVID-19 大流行导致雇佣卡车司机工资上涨了一些,卡车平均费率上涨了近一些,卡车司机职位空缺与成功匹配之间的差距解释了卡车费率的大幅上涨,但幅度较小。

Method myopia is defined as theoretical rhetoric absent empirical discernment regarding flavor-of-the-day econometric methodologies. This Fellows Address discusses why method myopia is pervasive, what factors contribute to the pervasiveness, why is likely it to increase, and finally, a possible remedy. To that end, incentive structures facing researchers, reviewers, and editors are considered within the life-cycle of a typical econometric methodology. Considering our discipline is empirically driven, there are potentially large costs by using flavor-of-the-day methodologies when an alternative -- possibly leading to different economic results and policy responses -- is the appropriate method. Furthermore, method myopia can notably restrict the set of research problems examined thereby creating additional, potentially large, opportunity costs. Finally, over-selling the superiority/completeness/correctness of results from such flavor-of-the-day methodologies to policy makers can not only be costly in the particular case, but can undermine the long-term credibility of our disciplinary advice to policy makers.

方法近视被定义为对时下流行的计量经济学方法缺乏经验鉴别力的理论空谈。本研究报告讨论了方法近视为何普遍存在、哪些因素导致了方法近视的普遍存在、方法近视为何有可能加剧,以及最后可能的补救措施。为此,我们将在典型计量经济学方法论的生命周期内考虑研究人员、审稿人和编辑所面临的激励结构。考虑到我们的学科是以经验为驱动力的,因此,当另一种方法--可能导致不同的经济结果和政策反应--是合适的方法时,使用时下流行的方法可能会带来巨大的成本。此外,方法近视会明显限制研究问题的范围,从而产生额外的、潜在的巨大机会成本。最后,向政策制定者过度推销这种时髦方法所得出结果的优越性/完整性/正确性,不仅会在特定情况下付出高昂代价,而且会损害我们向政策制定者提供的学科建议的长期可信度。

Price pass-through in the U.S. beef industry: Implications of feedlot capacity utilization 美国牛肉业的价格传递:饲养场产能利用率的影响

Transmission of prices, profits, and more generally, economic well-being across vertically connected sectors of agriculture have a long history of interest—arguably of most current interest in meat and livestock markets. Disruptions in live animal harvesting, especially from COVID-19, have corresponded with substantial market adjustment and hence elevated interest in inner-industry relationships, including from policymakers. This paper's main contribution is assessing how price changes in the U.S. feedlot industry manifest in feeder cattle markets. We use Ricardian rent theory as a framework to quantify price transmission by testing how price fluctuations actually pass through the supply chain versus theoretical expectations. We posit that the capacity utilization of feedlots changes because of market shocks, impacting price relationships. In the empirical model, when feedlot capacity utilization rates are below the 65% critical point, we find that both fed to feeder cattle and corn to feeder cattle pass-through rates are higher than hypothesized. When feedlot capacity utilization rates are high (>65%), estimated pass-through rates are lower and not statistically different from Ricardian rent theory. Understanding how prices pass through in the beef industry can help inform policy discussions about beef market competitiveness and promote efficient resource allocation.

价格、利润以及更广泛意义上的经济福利在纵向相连的农业部门之间的传递长期以来一直备受关注,可以说目前肉类和牲畜市场最令人关注。活畜收获的中断,尤其是 COVID-19 引起的中断,伴随着市场的大幅调整,从而提升了包括政策制定者在内的人们对行业内部关系的兴趣。本文的主要贡献在于评估了美国饲养场行业的价格变化如何体现在饲养牛市场上。我们以李嘉图租金理论为框架,通过检验价格波动在供应链中的实际传导情况与理论预期,对价格传导进行量化。我们认为,饲养场的产能利用率会因市场冲击而发生变化,从而影响价格关系。在实证模型中,当饲养场产能利用率低于 65% 临界点时,我们发现饲料到饲养牛和玉米到饲养牛的传递率都高于假设。当饲养场产能利用率较高(65%)时,估计的转嫁率较低,与李嘉图租金理论在统计上没有差异。了解牛肉产业的价格传递方式有助于为有关牛肉市场竞争力的政策讨论提供信息,并促进有效的资源分配。
