Performant agricultural advisory services (AAS) in Africa are crucial for improving the agricultural productivity and food security of the farm households. Yet, evidence-based study on the impacts of AAS on farm performance are scarce, especially in West African countries. This study evaluates the impact of access to AAS on input use and farm performance in Senegal, employing the instrumental variable and control function approaches accounting for selection bias. The approaches are also employed to several sub-samples to see if the impacts are heterogeneous across crop types and fertilizer use, and matching techniques are applied to test the robustness of the results. Results show that the highest positive impact of AAS is on yield, while the impacts on gross margin and improved seeds uptake are very modest. Access to AAS has no effect on fertilizer uptake. It also finds that AAS impacts positively cereal production and farmers using no fertilizer but has no effect on the legume and horticultural crop production and on farmers using fertilizer. Given the Senegalese government and donors have put a lot of effort into developing an efficient AAS system, a consideration of the identified weaknesses is required to improve its efficiency.

在非洲，有效的农业咨询服务（AAS）对于提高农业生产率和农户的粮食安全至关重要。然而，有关农业咨询服务对农场绩效影响的循证研究却很少，尤其是在西非国家。本研究采用工具变量法和控制函数法（考虑了选择偏差），评估了塞内加尔获得农业支持服务对投入品使用和农场绩效的影响。此外，还对若干子样本采用了这些方法，以了解不同作物类型和化肥使用情况下的影响是否存在差异，并采用匹配技术来检验结果的稳健性。结果表明，农田灌溉服务对产量的积极影响最大，而对毛利和改良种子使用率的影响则非常有限。获得农田灌溉服务对化肥使用量没有影响。研究还发现，农田灌溉服务对谷物生产和不使用化肥的农民有积极影响，但对豆类和园艺作物生产以及使用化肥的农民没有影响。鉴于塞内加尔政府和捐助方为发展高效的农业支持系统付出了大量努力，因此需要考虑已发现的不足之处，以提高其效率。[经济文献引用：问题 12、问题 16]

The deep integration of the agricultural digital economy and foreign trade is an important driving force for promoting high–quality economic development. Based on a theoretical analysis of the impact mechanisms of the agricultural digital economy on agricultural exports, this study empirically examines the impact and mechanism of the agricultural digital economy on agricultural exports using Chinese agricultural export data from 2011 to 2016. The relevant findings are threefold. (1) The agricultural digital economy significantly enhances the growth of China's agricultural exports, and the result remains robust after a series of robustness tests. (2) The heterogeneity analysis reveals that the agricultural digital economy has a greater role in promoting exports from quality frontier firms, primary agricultural products and exports to developed countries. (3) The mechanism analysis demonstrates that the agricultural digital economy promotes exports of agricultural products on the supply side most strongly through quality–enhancing and the information cost effects, improving product quality and reducing information expenditure to achieve export growth. On the demand side, domestic demand traction and external–demand creation effects exert a local market effect and stimulate import market demand to promote export growth.

This study aims to clarify the effects of health claims on consumer purchasing behavior and market power, using the Japanese yogurt market as a case study. For the analysis, the Berry, Levinsohn, and Pakes model was applied for estimations using product-level purchasing data. The main analysis results are as follows. First, consumers prefer brands with lower prices, higher protein, lower fat, lower carbohydrates, and foods for specified health uses (FOSHU). Second, from the value of own-price elasticity of market shares, the higher the price of a brand, the more sensitively consumers respond to price. From the value of the cross-price elasticity of market shares, strong competition exists among FOSHU brands, and the price of R-1 drink types tends to significantly impact the market shares of brands other than FOSHU brands. Third, the market power of each brand tends to be higher for lower-priced brands and lower for higher-priced brands. In terms of market power by manufacturer, Meiji has the highest both the weighted average and median values. However, both the weighted average and median values of Danone Japan are relatively lower than those of other manufacturers. Fourth, in terms of each brand's market power, brands with low prices and FOSHU labeling have high market power. These findings suggest that the acquisition of FOSHU brands in the Japanese yogurt market does not lead to a decline in market power (increase in price) and has positive effects for manufacturers, such as an increased market share.

本研究以日本酸奶市场为例，旨在阐明健康声称对消费者购买行为和市场力量的影响。在分析中，采用了 Berry、Levinsohn 和 Pakes 模型，利用产品层面的购买数据进行估计。主要分析结果如下。首先，消费者偏好价格较低、蛋白质含量较高、脂肪含量较低、碳水化合物含量较低的品牌，以及特定健康用途食品（FOSHU）。其次，从市场份额的自有价格弹性值来看，品牌价格越高，消费者对价格的反应越敏感。从市场份额的交叉价格弹性值来看，FOSHU 品牌之间存在激烈竞争，R-1 饮料类型的价格往往会对 FOSHU 品牌以外的其他品牌的市场份额产生显著影响。第三，各品牌的市场力量往往是低价品牌较高，高价品牌较低。就制造商的市场力量而言，明治的加权平均值和中位值都是最高的。然而，日本达能的加权平均值和中位值都相对低于其他制造商。第四，从各品牌的市场力量来看，价格低且贴有 FOSHU 标签的品牌具有较高的市场力量。这些研究结果表明，在日本酸奶市场收购 FOSHU 品牌并不会导致市场支配力下降（价格上涨），反而会对制造商产生积极影响，如增加市场份额。

Increased tourism demand provides an opportunity to boost rural development. This paper examines the impact of rural tourism policy reform on hospitality and restaurant enterprises in rural areas in Japan. In early 2016, the Japanese government introduced a policy to encourage the participation of nonfarm enterprises in the rural hospitality industry. Using a nationally representative dataset of rural hospitality enterprises in Japan, we employ the difference‐in‐differences method to assess the causal effects of the policy on the sales value, number of business days, and labor productivity of hospitality enterprises and restaurants in rural areas. We find that this reform resulted in a 15.6% increase and a 5.1% decrease in the sales value of nonfarm‐owned and farm‐owned homestay enterprises, respectively. Moreover, changes in the number of business days and labor productivity can be associated with the policy effect. We also find a significant policy effect on nonfarm‐owned restaurants.

Background: Proprioception is vital for motor control and can be disturbed, for example, due to fatigue or injury. Clinical feasible, reliable and valid tests of shoulder proprioception are warranted. The aim was to investigate the effects of local fatigue on shoulder proprioception and the reliability of a feasible joint position sense test using an experimental repeated measures design.

Method: Forty participants repeated a shoulder joint position sense test to assess test-retest reliability. The test was then utilized on a subgroup of handball players who were subjected to five bouts of a repeated throwing task with the dominant hand. The effect of local fatigue was investigated by comparing the fatigued with the non-fatigued shoulder.

Results: There was a significant interaction for the arm × bout (p = 0.028, η_p² = 0.20) and a significant effect for the arm (p = 0.034, η_p² = 0.35) with a significant decrease in joint position sense for the throwing arm compared to the non-throwing arm. The intraclass correlation coefficient was 0.78 (95% CI = [0.57; 0.89]). The standard error of measurement between trials was 0.70° (range: 0.57°-0.90°).

Discussion: The results indicate that repeated throwing to fatigue disturbs shoulder joint position sense. Assessment with the modified test showed acceptable reliability and can be a valuable assessment tool in the clinic.

背景：本体感觉对运动控制至关重要，但可能因疲劳或受伤等原因而受到干扰。临床上需要对肩部本体感觉进行可行、可靠和有效的测试。本研究旨在通过实验性重复测量设计，研究局部疲劳对肩部本体感觉的影响以及可行的关节位置感测试的可靠性：方法：40 名参与者重复进行肩关节位置感测试，以评估测试重复可靠性。然后在手球运动员分组中使用该测试，让他们用优势手进行五次重复投掷任务。通过比较疲劳和非疲劳肩部，研究了局部疲劳的影响：结果：与非投掷手臂相比，投掷手臂的关节位置感明显下降，手臂×回合存在明显的交互作用（p = 0.028，ηp2 = 0.20），手臂存在明显的效应（p = 0.034，ηp2 = 0.35）。类内相关系数为 0.78 (95% CI = [0.57; 0.89])。试验之间的测量标准误差为 0.70°（范围：0.57°-0.90°）：讨论：研究结果表明，反复投掷致疲劳会干扰肩关节位置感。讨论：结果表明，疲劳状态下的反复投掷会干扰肩关节位置感，而改良测试的评估结果显示其可靠性是可以接受的，可以作为临床上一种有价值的评估工具。

This study examines whether the market competitiveness of farm loan suppliers is affected by the US tax policy for the farm credit system (FCS) and its potential spillover on the farmers' cost of borrowing. We exploit the variation in the corporate income tax rate to estimate its relationship with the farm debt share of the FCS and the potential spillover effect on the estimated cost of borrowing for agricultural loans. Results suggest that a 10% rise in the state (federal) tax rate is associated with an increase in FCS's total farm debt market share by 1.76% (3.76%). A 10% rise in the FCS total farm debt market share tends to increase the cost of borrowing on agricultural loans by 0.06%. Overall, the findings imply that favorable tax treatment could increase FCS' competitiveness in the agricultural lending market. Also, an increase in the interest rate on farm debt is correlated with the increasing market share of FCS in the agricultural credit market. [EconLit Citations: Q14, N22, H2, H7, G21].

本研究探讨了农业贷款供应商的市场竞争力是否受到美国农业信贷系统（FCS）税收政策的影响，以及该政策对农民借贷成本的潜在溢出效应。我们利用企业所得税税率的变化来估算其与 FCS 的农场债务份额之间的关系，以及对农业贷款借贷成本估算的潜在溢出效应。结果表明，州（联邦）税率每上升 10%，金融服务公司的总农业债务市场份额就会增加 1.76% (3.76%)。联邦统计局的农场债务市场份额每增加 10%，农业贷款的借贷成本就会增加 0.06%。总之，研究结果表明，优惠的税收待遇可以提高金融服务公司在农业贷款市场上的竞争力。此外，农业债务利率的增加与金融服务公司在农业信贷市场中的市场份额增加相关。[经济文献引用：Q14, N22, H2, H7, G21]。

In contrast to the widespread adoption of agricultural commodities modified using biotechnology, the adoption rate of bioengineered specialty crops by growers remains low. The use of bioengineered crops has been controversial since their introduction in the 1990s due to concerns about their potentially harmful effects to human health, the environment, and other socioeconomic issues. To identify grower preferences, perceived opportunities, and barriers to growing bioengineered crops, we surveyed Minnesota specialty crop growers using a web-based survey. The survey measured whether adoption rates are influenced by the specific trait of the modification, the method of bioengineering (genetically modified [GM] vs. genetically edited [GE]), or the end use of the crop being grown (ornamental vs food). Overall willingness-to-pay for both GM and GE potatoes was significantly lower than for conventional potatoes, and nearly a quarter (25%) of our respondents never chose a bioengineered option no matter the benefits. Results were similar for petunias, but fewer respondents (18%) refused to consider the bioengineering option. The type of bioengineering did not have as significant an impact on adoption rate as price or end use. The bioengineered ornamental crop had a higher willingness to adopt than the bioengineered food crop.

与广泛采用生物技术改造农产品形成鲜明对比的是，种植者对生物工程特种作物的采用率仍然很低。由于担心生物工程作物可能对人类健康、环境和其他社会经济问题产生有害影响，自 20 世纪 90 年代引入以来，生物工程作物的使用一直备受争议。为了确定种植者的偏好、感知到的机遇以及种植生物工程作物的障碍，我们利用网络调查对明尼苏达州特种作物种植者进行了调查。该调查衡量了采用率是否受改良的具体性状、生物工程方法（转基因 [GM] 与基因编辑 [GE]）或所种植作物的最终用途（观赏与食用）的影响。对转基因马铃薯和基因工程马铃薯的总体支付意愿明显低于对传统马铃薯的支付意愿，近四分之一（25%）的受访者无论收益如何都不会选择生物工程选项。牵牛花的结果与此类似，但拒绝考虑生物工程方案的受访者较少（18%）。生物工程的类型对采用率的影响不如价格或最终用途大。生物工程观赏作物的采用意愿高于生物工程粮食作物。[EconLit引文：Q160 农业研发；农业技术；生物燃料；农业推广服务。O330 技术变革：选择与后果；扩散过程]。

This article examines the impact of trade liberalization on export prices and quality. The article is innovative in two respects. First, unlike previous studies, it considers both input and output tariffs simultaneously in a theoretical model. Second, it empirically tests the effects of a combination of specific and ad-valorem tariffs on quality improvement. The theoretical analysis suggests that when firms face reduced output and input tariffs, they tend to improve their export quality and increase export prices. Using export data from 33 OECD countries, the empirical analysis demonstrates that output tariff reduction increases export quality but decreases prices. However, the effects of input tariff reduction on price and quality depend on product differentiation. The results also indicate that the presence of specific tariffs increase product quality while amplifying the positive effects of the reduction of ad-valorem tariffs on quality. This implies that to improve export quality, reducing ad-valorem tariffs is more efficient than a specific tariff. [EconLit Citations: F12, F14, Q17].

本文探讨了贸易自由化对出口价格和质量的影响。文章在两个方面具有创新性。首先，与以往的研究不同，它在理论模型中同时考虑了投入和产出关税。其次，文章通过实证检验了特定关税和从价关税相结合对质量提高的影响。理论分析表明，当企业面临产出和投入关税降低时，它们倾向于提高出口质量和出口价格。利用 33 个经合组织国家的出口数据进行的实证分析表明，降低产出关税会提高出口质量，但会降低价格。然而，降低投入品关税对价格和质量的影响取决于产品差异。结果还表明，特定关税的存在提高了产品质量，同时放大了从价关税降低对质量的积极影响。这意味着，要提高出口质量，降低从价关税比特定关税更有效。[经济学引文：F12、F14、Q17]。

The “meat” marketing of new plant-based burgers distinguished them from traditional vegan burgers, yet it is still unknown if and to what extent this advertising appeals to meat consumers. We employ a novel digital advertisement dataset from Nielsen Ad Intel to investigate the market entry and advertising patterns of the Impossible Burger, one of the leading brands in the plant-based meat market. By merging weekly ad views at the DMA market level with Nielsen Homescan Panel, we find that prior purchases of meat burgers reduce the likelihood of consumers buying the new plant-based burger, whereas past vegan burger purchases elevate this probability. While advertising did boost the average purchasing likelihood for the Impossible Burger, the enhancement in purchase probability for meat burger consumers is approximately one fifth of that observed for vegan burger consumers. These findings have implications to effectively marketing plant-based meat products to different consumer groups [EconLit Citations: D12, M37, M31, L66].

新型植物性汉堡的 "肉类 "营销将它们与传统的素食汉堡区分开来，但这种广告是否以及在多大程度上吸引了肉类消费者仍是个未知数。我们利用尼尔森广告英特尔（Nielsen Ad Intel）提供的新型数字广告数据集，对植物肉类市场的领先品牌之一 "不可能汉堡"（Impossible Burger）的市场进入和广告模式进行了调查。通过将 DMA 市场层面的每周广告浏览量与尼尔森家庭扫描面板（Nielsen Homescan Panel）合并，我们发现消费者之前购买过肉类汉堡会降低其购买新植物汉堡的可能性，而之前购买过素食汉堡则会提高这一可能性。虽然广告确实提高了 "不可能汉堡 "的平均购买可能性，但肉类汉堡消费者购买可能性的提高大约是素食汉堡消费者购买可能性的五分之一。这些发现对有效地向不同消费群体推销植物性肉类产品具有重要意义[经济学引文：D12, M37, M31, L66]。

This paper investigates the effects of extremely high temperatures on wage losses for workers in the Chinese agri-food industry. Our estimated results suggest extreme heat is associated with a decrease in worker wages, and that these welfare losses could be attributed to the adverse impacts of extremely hot days on worker productivity. We also observe that, compared to male workers, female workers are more likely to bear wage losses when exposed to extremely hot weather. Furthermore, workers in private firms may experience more wage losses due to extremely hot days than those in other ownership types. Regarding the industry-level heterogeneity analysis, we find that wage losses in the agri-food manufacturing industry are more severe than those in the agri-food processing industry, while no significant wage losses are observed in the beverages and alcohol industry. In the long term, wage losses induced by climate change are projected to rise by 10.93% under RCP8.5, if no extra adaptation actions are implemented. [EconLit Citations: O13, P46, Q54]

本文研究了极端高温对中国农业食品行业工人工资损失的影响。我们的估计结果表明，极端高温与工人工资下降有关，而这些福利损失可能是由于极端高温天对工人生产率的不利影响造成的。我们还发现，与男性工人相比，女性工人在极端高温天气下更容易遭受工资损失。此外，与其他所有制类型的企业相比，私营企业的工人可能因极端高温天而遭受更多工资损失。关于行业层面的异质性分析，我们发现农业食品制造业的工资损失比农业食品加工业更为严重，而饮料和酒类行业则没有观察到明显的工资损失。从长期来看，如果不采取额外的适应行动，预计在 RCP8.5 条件下，气候变化引起的工资损失将增加 10.93%。[经济学引文：O13, P46, Q54].
