The Impacts of a Local Enhanced Management Area on Groundwater Use for Crop Production
当地强化管理区对农作物生产地下水利用的影响
Lambert, Dayton M.; Golden, Bill; Lambert, Lixia; Guerrero, Bridget
Abstract：This study evaluates the impact of groundwater restrictions under Kansas's Local Enhanced Management Area program, focusing on the Sheridan-6 (SD6) region from 2013 to 2023. Using difference-in-differences regressions and well-level panel data, we find that SD6 irrigators reduced water use intensity by 16 percent and pumping costs by $5.48 per acre on average. No significant changes in irrigated acreage occurred. Differences from the control group decreased after 2018 when irrigators outside SD6 adopted less stringent water use policies. Results suggest that locally governed, farmer-led restrictions can reduce water use without diminishing productivity, though policy diffusion and adaptive responses complicate long-term measurement of conservation outcomes.
摘要：本研究评估了堪萨斯州地方强化管理区计划下地下水限制的影响，重点关注 2013 年至 2023 年的 Sheridan-6 (SD6) 地区。利用双重差分回归和井位面板数据，我们发现 SD6 灌溉机平均降低了 16% 的用水强度，每英亩抽水成本降低了 5.48 美元。灌溉面积无明显变化 发生。 2018 年之后，当 SD6 之外的灌溉者采取了不太严格的用水政策时，与对照组的差异有所减小。结果表明，地方管理、农民主导的限制措施可以在不降低生产力的情况下减少用水量，尽管政策扩散和适应性反应使保护成果的长期衡量变得复杂。

Does Complexity Pay? Forecasting Corn and Soybean Yields Using Crop Condition Ratings
复杂性值得吗？使用作物状况评级预测玉米和大豆产量
Li, Jiarui; Irwin, Scott H.; Hubbs, Todd
Abstract：We compare the accuracy of crop condition models from existing literature in forecasting U.S. corn and soybean yields. The data for the study consists of weekly state and national crop condition ratings from the USDA over 1986 through 2022. A battery of statistical tests is applied to perform out-of-sample forecasts over 2000 through 2022. While there are differences in the accuracy of the models, test results are uniform in suggesting that no model has statistically significant superior forecast accuracy. A key finding is that relatively simple models perform just as well as more complex and computationally demanding models.
摘要：我们比较了现有文献中作物状况模型在预测美国玉米和大豆产量方面的准确性。该研究的数据包括美国农业部 1986 年至 2022 年每周的各州和国家作物状况评级。应用了一系列统计测试来执行 2000 年至 2022 年的样本外预测。虽然模型的准确性存在差异， 测试结果一致表明，没有模型具有统计上显着的优越预测精度。一个重要的发现是，相对简单的模型与更复杂且计算要求较高的模型表现得一样好。

Grassland Property Rights and the Size-Productivity Relationship: Evidence from Pastoral China
草原产权与规模-生产力关系：来自中国牧区的证据
Zhang, Mingxue; Li, Dongqing
Abstract：Using household panel data from five major pastoral provinces in China, we illustrate a robust inverse relationship (IR) between grassland size and productivity. Our investigation reveals that the certification of grassland property rights significantly contributes to this IR. The persistence of the IR among households with certified grassland-use rights, contrasted with its absence among those with ambiguous rights, highlights its role. The emergence of grassland misallocation and fragmentation during the property rights certification process appears detrimental to grassland productivity, potentially explaining this phenomenon. Additionally, herders' adaptive strategies, like renting grassland and cooperative management, may help mitigate the IR.
摘要：我们利用中国五个主要牧区省份的家庭面板数据，说明了草地面积和生产力之间存在强大的反比关系（IR）。我们的调查显示，草原产权认证对这一IR有显着贡献。拥有草原使用权认证的家庭持续存在IR，而拥有草原使用权的家庭则没有IR 模糊的权利，凸显其作用。产权认证过程中出现的草地错配和破碎化似乎不利于草地生产力，这可能解释了这一现象。此外，牧民的适应性策略，如租用草地和合作管理，可能有助于减轻IR。

Heterogeneous Effects of COVID-19 on Fruit and Vegetable Markets
COVID-19 对水果和蔬菜市场的异质影响
Kennedy, Odongo; Mittelhammer, Ron C.; McCluskey, Jill J.; Astill, Gregory
Abstract：The COVID-19 pandemic caused abrupt changes in food purchases and consumer behavior because of both supply and demand shocks. Stay-at-home orders resulted in large reductions in demand for food consumed in food-away-from-home settings. At the same time, the demand for food purchased at grocery stores and online spiked. We analyze the association between pandemic, related media coverage, and prices of specialty crop commodities. We find that prices of specialty crops consumed mostly away from home exhibited a demonstrative negative relationship with the pandemic and associated media coverage compared to specialty crops consumed mostly at home.
摘要：由于供需冲击，COVID-19 大流行导致食品购买和消费者行为发生突然变化。居家订单导致外出就餐的食品需求大幅减少。与此同时，在杂货店和网上购买食品的需求激增。我们分析流行病、相关媒体报道和价格之间的关联 特种作物商品。我们发现，与主要在国内消费的特种作物相比，主要在国外消费的特种作物的价格与大流行和相关媒体报道呈现出明显的负相关关系。

A Different "Law of One Price": Unintended Impacts of Uniform Price Regulation in Livestock Markets
不同的"一价法则"：畜牧市场统一价格监管的意外影响
Ramsey, A. Ford; Goodwin, Barry K.
Abstract：We investigate the impacts of a short-lived change in Missouri's livestock marketing regulations intended to encourage homogeneous pricing for livestock sold in Missouri. Missouri's Livestock Marketing Law of 1999 changed the legal structure governing livestock purchases, creating requirements for meatpackers to adjust purchasing behavior to prevent discriminatory pricing. The legislation resulted in a decrease in the number of hogs produced and sold in Missouri. The impacts were detrimental to the Missouri livestock sector, leading policymakers to eventually abandon uniform pricing standards.
摘要：本研究调查了密苏里州一项短期牲畜营销法规变化的影响，该法规旨在鼓励对在密苏里州销售的牲畜进行同质化定价。1999年《密苏里州牲畜营销法》改变了管理牲畜采购的法律结构，要求肉类包装商调整采购行为以防止歧视性定价。该立法导致密苏里州生产和销售的生猪数量减少。这些影响对密苏里州畜牧业产生了不利影响，导致政策制定者最终放弃了统一定价标准。

Small Precautionary Response to Risk in Corn Seeding Rate Decisions
对玉米播种量决策风险的小规模预防性反应
Zhao, Yue; Hennessy, David A.; Lindsey, Alexander J.
Abstract：We find that farmers' precautionary motives have small impact on optimal corn seeding rates, contrary to their significant influence on savings and asset decisions. Our conceptual model shows that precautionary motives increase seeding rates when higher seeding rates reduce yield risk and decrease them when higher seeding rates increase yield risk. Analysis of Ohio and Illinois field data reveals a U-shaped yield risk response to seeding rates. Simulations indicate a 0.2% seeding rate increase in Ohio and a 0.19% decrease in Illinois due to precautionary motives, while yield insurance reduces optimal seeding rates in both states by up to 2%.
摘要：我们发现，农民的预防动机对最佳玉米播种率的影响很小，而对储蓄和资产决策的影响却很大。我们的概念模型表明，当较高的播种率降低产量风险时，预防性动机会提高播种率；而当较高的播种率增加产量风险时，预防性动机也会降低播种率。对俄亥俄州和伊利诺伊州现场数据的分析揭示了 U 形产量风险对播种率的反应。模拟显示，由于预防性动机，俄亥俄州的播种率增加了 0.2%，伊利诺伊州的播种率下降了 0.19%，而产量保险将这两个州的最佳播种率降低了 2%。

Impacts of Deportation of Undocumented Workers on the Broiler Supply Chain
驱逐无证工人对肉鸡供应链的影响
Devadoss, Stephen; Luckstead, Jeff
Abstract：This study explores the impacts of deportation of the undocumented workers on various segments of the poultry supply chain using a model comprising domestic workers and undocumented workers. The results show that the deportation of 20% of undocumented workers in the poultry supply chain increases the wage rates by 7.82% which raises the cost of production and chicken product prices. Lack of labor availability due to this deportation policy causes production to decline in every segment of the poultry supply chain. Poultry producers' welfare declines by $63.85 million. Price inflation for chicken products occurs, ranging from 1.41% for feet to 2.94% for ready-to-eat products. Domestic consumption of chicken products falls, ranging from 0.73% for whole chickens to 2.11% for ready-to-eat products. US consumers' surplus declines by $1.94 billion.
摘要：本研究使用包含家庭工人和无证工人的模型探讨了驱逐无证工人对家禽供应链各个环节的影响。结果显示，驱逐家禽供应链中20%的无证工人使工资率增加7.82%，从而提高了生产成本和鸡肉产品价格。缺乏劳动力 由于这一驱逐政策，导致家禽供应链各个环节的产量下降。家禽生产者的福利减少了 6385 万美元。鸡肉产品价格出现上涨，从鸡脚的 1.41% 到即食产品的 2.94% 不等。国内鸡肉产品消费量下降，整鸡下降 0.73%，即食产品下降 2.11%。美国消费者的 盈余减少19.4亿美元。

Global Agricultural Productivity: Insights from a Dynamic Gravity Model
全球农业生产力：动态重力模型的见解
Luckstead, Jeff
Abstract：This study estimates an aggregate agricultural industry dynamic structural gravity model with capital accumulation to assess the relationship between capital accumulation and determinants of total factor productivity (TFP) in agricultural trade flows. The Armington elasticity of substitution is 1.47. Institutional variables government investment, business regulations, legal enforcement of contracts, and communication technology are key drivers of global agricultural TFP. The capital stock transition parameter is 34.6%. Counterfactual analyses show that increasing all countries' TFP and improving institutional quality in countries with low-quality institutions generally raise exports, imports, output, capital stock, and welfare.
摘要：本研究估计了带有资本积累的农业产业动态结构引力模型，以评估农业贸易流动中资本积累与全要素生产率（TFP）决定因素之间的关系。阿明顿替代弹性为 1.47。制度变量政府投资、商业法规、合同的法律执行、 和通信技术是全球农业全要素生产率的关键驱动力。股本转换参数为34.6%。反事实分析表明，增加所有国家的全要素生产率并提高制度质量低下的国家的制度质量通常会提高出口、进口、产出、资本存量和福利。

Price Dynamics and Weather Anomalies in Agricultural Supply Chains
农业供应链的价格动态和天气异常
Ghoshray, Atanu; Ghosh, Madhusudan; Lim, Sunghun
Abstract：In developing countries, certain specialty crops, highly consumed for their culture, often face increased vulnerability to price fluctuations along supply chains due to natural disasters and climate crises. Onions in India are a prime example. Leveraging monthly-level price data along the onion supply chain from March 2010 to April 2022, this study proposes a VAR-X model that explores the price dynamics among onion arrivals, retail and wholesale prices, alongside rainfall anomalies across four major cities in India. Our core finding reveals that rainfall anomalies have a significant yet contrasting effect on prices and arrivals along the onion supply chain.
摘要：在发展中国家，某些因种植而大量消费的特种作物往往更容易受到自然灾害和气候危机导致的供应链价格波动的影响。印度的洋葱就是一个很好的例子。本研究利用 2010 年 3 月至 2022 年 4 月洋葱供应链的月度价格数据，提出了一个探索价格动态的 VAR-X 模型 洋葱抵达量、零售和批发价格以及印度四个主要城市的降雨异常。我们的核心发现表明，降雨异常对洋葱供应链上的价格和到货量具有显着但截然不同的影响。
