In Amazon's marketplaces across the globe, multiple sellers sell the same product, leading Amazon to introduce BuyBox. This box‐like feature, located on the top‐right corner of product pages, prominently displays a single seller at a given time. Using a choice model and a panel dataset of over 290,000 unique grocery products from five countries, our study investigates the key factors that influence BuyBox assignments. We found that winning the BuyBox is primarily determined by competitive pricing—being the lowest‐price seller for a 180‐day period significantly improves the chances of a BuyBox assignment. Furthermore, maintaining low current product prices, low sales ranks, and minimal out‐of‐stock percentages are crucial in becoming a BuyBox seller. These findings affect Amazon and its extensive network of over 2 million third‐party sellers, who navigate the increasingly competitive and dynamic E‐commerce landscape.

This study introduces a sophisticated model for evaluating bargaining power within the agricultural production service market, using data from China's Land Economy Survey and the bilateral stochastic frontier model. The findings indicate: (1) Suppliers elevate prices by 26.77% above the benchmark, while demanders reduce them by 24.36%, culminating in a market price that surpasses the benchmark. (2) Labor outflow and aging populations drive suppliers to further increase market prices. (3) Variations in individual characteristics underpin the disparity in bargaining power between suppliers and demanders. The study underscores the disadvantaged and heterogeneous nature of farmers (demanders), advocating for a recalibration of subsidy distribution to benefit farmers directly, rather than agricultural production service organizations, and the establishment of differentiated subsidy systems.

The objective of this study was to evaluate differences in the technical efficiency of alternative milk production systems on Brazilian farms. Using a panel from 2014 to 2021 (1117 observations of 383 dairy farms) we compare the technical efficiency of more recently adopted Compost‐bedded Pack Barns (CPB) with that of Semi‐confinement (SC), and Unstructured confinement (UNS) systems. A stochastic frontier was estimated by a Generalized True Random Effects to assess the relationship between technical efficiency and the production systems adopted, decompose efficiency into Transient (short‐term) and Persistent (long‐term) components, and control for unobserved heterogeneity. We found that farms using confined systems are more efficient than those using semi‐confined systems. The decomposition of the Overall Technical Efficiency in its Persistent and Transient components suggests that farmers can be more efficient when dealing with short‐term shocks than when deciding which system to use. The use of more capital‐intensive technologies such as CPB may provide opportunities to improve dairy farm profitability and productivity growth in Brazil.

This study explores the rent price ratio in agricultural land markets, crucial for evaluating market efficiency, policy needs, and farmer decision‐making. Traditionally, the analyses faced challenges due to the absence of concurrent sale and rent data for the same land, potentially leading to biased results. This research avoids this problem by utilizing a unique dataset from Eastern Germany, encompassing auction data from 2016 to 2019. This dataset is distinctive, containing both the purchase and lease price offers by individual farmers for the same agricultural land at a single point. Thus, this study overcomes the conventional limitations of using aggregated or non‐contemporaneous data. Hence, the focal point is to unravel the intricate relationship between individual rent price ratios and a myriad of influencing factors, including land characteristics and local farming structures. The use of Generalized Additive Models for Location, Shape, and Scale provides a robust framework for this analysis, offering a nuanced understanding of the distributional properties of individual rent price ratios. The study provides robust empirical evidence that highlights the need for adaptive and region‐specific policies if policy makers insist on intervening in the agricultural land market. Furthermore, promising points of departure for future research are identified. [EconLit Citation: Q15].

Rice is a basic component in the diet of more than half of the world's population, with 95% of its production destined for human consumption. Spain is the second rice producer in the European Union (EU), geographically located in four autonomous communities contributing to the local economy. This study aims at assessing the productive efficiency of rice farms in this country. To our knowledge, no previous work has dealt with the performance of rice framers in the EU in general and in Spain in particular. We used the Generalized True Ramdom‐effects model to estimate the persistent and transient efficiency levels of farms and identifying the production risk factors using a sample of 158 rice farms over the period 2014–2017. Empirical findings reveal an overall efficiency level of 0.81 on average, mainly explained by the long‐term efficiency component. Moreover, results show an important room for efficiency improvement at the short‐term to enhance productive management skills of farmers. Finally, labor, fertilizer, water and insurance spending are likely to be risk‐decreasing factors. [EconLit Citations: C13, D22, Q12].

Why do certain new crop varieties fail to gain popularity among farmers despite their proven superiority in scientific field trials and on‐farm demonstrations? Empirical microlevel studies in agricultural economics usually address this question from a household or farmer perspective, neglecting the broader socio‐institutional and economic context against which varietal dissemination takes place. In the present study, we explore the relationship between wheat seed delivery networks and varietal turnover, using data from farmers' fields in eastern India. An extensive survey encompassing 7648 wheat farmers was conducted to capture wheat production practices across 31 districts of Bihar and 9 districts of eastern Uttar Pradesh. Additional qualitative interviews led to the initial impression that farmers' selection of varieties often precedes their choice of seed source, challenging the prevailing assumptions about the causal direction of this relationship. To address the challenge of reverse causality between varietal selection and seed source preference, we employed an instrumental variable regression framework. Although new wheat varieties are available in the market, a substantial majority of farmers opt for old ones. Farmers' decisions regarding the selection of wheat varieties and seed sources are not straightforward, and their preference for wheat varieties significantly impacts their seed source selection, indicating a hitherto unexplored bidirectional relationship. Understanding this complex relationship has significant strategic implications for stakeholders in the seed supply system, offering policy recommendations for enhancing varietal turnover rates and encouraging the widespread adoption of new, improved varieties among smallholders. Such initiatives hold the promise of enhancing system resilience and food security in developing countries. [EconLit Citations: O3, Q1, Q16, Q18].

This study analyzes the impact of adopting sustainable agricultural practices (SAPs) with or without chemical pesticides on farmers' technical efficiency. We compared three groups of farmers: nonadopters, those adopting SAPs and using chemical pesticides, and those adopting SAPs in the pesticide‐free mode. The study data covered 1912 rural households in Burkina Faso for the 2016–2017 agricultural season. We used an endogenous frontier model and a matching method to address sample selection for both observables and unobservables. The results show that the adoption of pesticide‐free SAPs reduces technical inefficiency compared with the practice of adopting SAPs with pesticides and nonadoption of SAPs. However, our findings show that compared with the nonadoption of SAPs, adoption of SAPs with chemical pesticides did not have a significant effect on technical efficiency. For more efficient and sustainable agriculture, policies should further promote SAPs while advancing biological pest management techniques, as opposed to the use of chemical pesticides.

本研究分析了采用或不采用化学农药的可持续农业实践（SAP）对农民技术效率的影响。我们对三组农民进行了比较：非采用者、采用 SAP 并使用化学农药的农民和采用 SAP 无农药模式的农民。研究数据涵盖布基纳法索 2016-2017 年农季的 1912 个农村家庭。我们使用了内生前沿模型和匹配方法来解决可观测变量和不可观测变量的样本选择问题。结果表明，与采用含农药的农业结构调整方案和不采用农业结构调整方案的做法相比，采用不含农药的农业结构调整方案降低了技术无效率。然而，我们的研究结果表明，与不采用结构调整方案相比，采用含化学农药的结构调整方案对技术效率没有显著影响。为了提高农业的效率和可持续发展，政策应进一步推广 SAP，同时推进病虫害生物防治技术，而不是使用化学农药。[经济学引文：问题 1、问题 12、问题 15、问题 16、问题 56]。

This study examines producer participation choices considering a variety of potential benefits linked to state‐sponsored marketing programs, using a real choice dataset of farmers in Missouri. Multinomial logit models are employed to predict determinants of farmer enrollment in three tiers of the Missouri Grown local food marketing program: free, $50, and $100 memberships. We find that farmers who expect to increase sales or receive special services from the program are more likely to choose paid membership levels, while those who seek new opportunities are more associated with free participation. Furthermore, farms with annual sales above $150,000 and those with male or white decision‐makers are more likely to be $100 members, while young and beginning farmers tend to participate at a paid tier of $50 in the program.

Despite the global increase in poultry consumption, there are different preferences for chicken products in different countries. In Ghana, two main categories dominate the market: live/fresh whole chickens and imported frozen chicken parts. This study leverages data from 13,201 households to explore Ghanaian demand dynamics for these products using the Quadratic Almost Ideal Demand System. Findings reveal stark differences between the two. Live/fresh whole chickens, considered luxury goods, display a complex interplay with other non‐chicken meat products, cultural festivities, and various sociodemographic factors. Meanwhile, frozen chicken parts, seen as necessities, exhibit different demand shifters and peak consumption periods. Importantly, these two categories emerge as distinct products, signaling to policymakers the need for differentiated strategies. Simulated policy scenarios further emphasize that reducing prices of live/fresh chickens significantly boosts domestic chicken demand more than policies raising prices of frozen parts. However, the broader implications on alternative protein sources differ between the two policy types. We urge policymakers to adopt an integrated approach, considering these nuances, to strengthen Ghana's domestic poultry sector without unintended market disruptions.

Outsourcing pest and disease control (PDC) has grown rapidly worldwide, especially in developing countries. Although numerous studies have investigated various advantages of outsourcing PDC, little is known about its impact on pesticide expenditure. This study addresses the gap by estimating the impact of outsourcing PDC on pesticide expenditure using data collected from 448 rice farmers in China. We employ an endogenous treatment regression (ETR) model and an instrumental variable quantile regression (IVQR) model to investigate the homogenous and heterogeneous impacts of outsourcing PDC, respectively. The results estimated by the ETR model show that outsourcing PDC decreases total pesticide expenditure. The reduction in herbicide expenditure due to outsourcing PDC is greater than the reduction in insecticide expenditure. The results estimated by the IVQR model reveal that the pesticide expenditure reduction effect of outsourcing PDC is larger among farmers with higher pesticide expenditure. Our findings generally suggest that it is necessary to take outsourcing PDC into consideration when designing policies to promote pesticide expenditure reduction and protect the ecological environment and human health.
