This article aimed to investigate the contribution of technical efficiency gains to reducing the emission of greenhouse gases in Brazilian sugarcane production and to estimate the monetary compensation that producers should receive to reduce pollution. Using an output distance function and its duality with the revenue function, we estimated the technical efficiency of sugarcane production in Brazilian municipalities and the shadow price of reducing carbon dioxide (CO2) emissions from the production of this crop. The main result was an overall technical efficiency average of 81%, which indicates that if producers adopt better management practices, the sugarcane production could be expanded by 19% with a contraction by the same magnitude in CO2 emissions. We also estimated a mean shadow price of R$9.18 per ton of carbon dioxide, with the highest estimated values in the states of Mato Grosso do Sul, Paraná, Mato Grosso, and Bahia. However, in the state of São Paulo, the most representative national producer, the estimated shadow price is R$6.34 per ton of carbon dioxide. In this sense, public policies, especially through public financing and public technical assistance, could potentially mitigate the producers' losses in the short run since pollution decline usually requires more mechanization.

本文旨在研究技术效率提高对减少巴西甘蔗生产中温室气体排放的贡献,并估计生产者应获得的货币补偿以减少污染。利用产出距离函数及其与收入函数的对偶性,我们估计了巴西各城市甘蔗生产的技术效率以及减少这种作物生产中二氧化碳排放的影子价格。主要结果是总体技术效率平均为81%,这表明如果生产者采取更好的管理措施,甘蔗产量可以扩大19%,二氧化碳排放量也可以减少相同幅度。我们还估计,每吨二氧化碳的影子价格平均为9.18雷亚尔,其中南马托格罗索州、帕拉巴州、马托格罗索州和巴伊亚州的影子价格最高。然而,在最具代表性的全国二氧化碳生产商圣保罗州,影子价格估计为每吨6.34雷亚尔。在这个意义上,公共政策,特别是通过公共筹资和公共技术援助,可能在短期内减轻生产者的损失,因为减少污染通常需要更多的机械化。

We investigate the economic feasibility of the Brazilian crop-livestock integration system. Under this system, the Brazilian farmer can produce soybeans, corn, and graze for cattle on the same land during one crop year. This technology can substantially increase agricultural production in the country. We contrasted the stochastic net present value of traditional farming with the integrated system under four different scenarios. To rank the scenarios, we use stochastic dominance methods. The results suggest more significant economic gains for crop-livestock integration scenarios.

我们调查了巴西农牧一体化系统的经济可行性。在这种制度下,巴西农民可以在一个作物年里在同一块土地上生产大豆、玉米和放牧牛。这项技术可以大大提高该国的农业产量。在四种不同情景下,对比了传统农业与综合农业的随机净现值。为了对场景进行排序,我们使用随机优势方法。结果表明,农牧一体化方案的经济收益更显著。

Smallholder agriculture remains a cornerstone for economic development and poverty reduction in Latin America. Their transition to sustainable agricultural production is critical in the face of the environmental challenges posed by conventional farming practices and is a key pathway to achieving the United Nations' Sustainable Development Goals. This study examines the effects of Sustainable Agricultural Practices (SAP) adoption on coffee production and technical efficiency (TE) among smallholders in Peru, focusing on both observable and unobservable factors. Using a multistage framework, we employ propensity score matching to control for observable factors, estimate a Stochastic Production Frontier model with sample selection bias correction to control for unobservable factors, and assess technological differences using a metafrontier approach. Our analysis of pooled cross-sectional data from 2017 to 2019 indicates that age, farm accessibility, and having Quechua as a first language are factors that make farmers more likely to adopt SAP. Although SAP adopters initially show higher production levels, the difference is not statistically significant after accounting for unobserved factors. However, SAP adopters utilize better technology and exhibit higher TE compared to non-adopters, highlighting the potential benefits of promoting sustainable practices in smallholder agriculture.

小农农业仍然是拉丁美洲经济发展和减贫的基石。面对传统耕作方式带来的环境挑战,他们向可持续农业生产的过渡至关重要,也是实现联合国可持续发展目标的关键途径。本研究考察了采用可持续农业实践(SAP)对秘鲁小农咖啡生产和技术效率(TE)的影响,重点关注可观察和不可观察的因素。使用多阶段框架,我们使用倾向得分匹配来控制可观察因素,估计随机生产前沿模型与样本选择偏差校正来控制不可观察因素,并使用元前沿方法评估技术差异。我们对2017年至2019年的汇总横截面数据的分析表明,年龄、农场可及性和以克丘瓦语为第一语言是促使农民更有可能采用SAP的因素。尽管SAP采用者最初表现出更高的生产水平,但在考虑了未观察到的因素后,这种差异在统计学上并不显著。然而,与非采用者相比,SAP采用者利用了更好的技术,表现出更高的TE,突出了在小农农业中促进可持续实践的潜在好处。

The Effects of International Orientation on the Dimensions of the Environmental Performance of Agri-Food Companies: A Chilean Perspective 国际导向对农业食品公司环境绩效维度的影响:智利视角

Like other Latin American economies, Chile has significantly increased its presence in international agriculture markets. Agricultural commodities are primarily developed within specialized exporters or multinational enterprises and exported to several different countries. In Chile, the fruit sector accounts for almost half of total exports. Internationally oriented companies explore business opportunities in foreign markets and invest adequate resources in international operations. In addition, more internationally oriented companies could be more inclined to invest in green practices due to external pressures and, consequently, achieve higher environmental performance. In this context, environmental performance is related to the extent to which available natural resources are protected during the production, delivery, and consumption of agricultural products. To the best of our knowledge, there is scattered evidence of the relationship between international orientation and the environmental performance of agri-food companies, especially in Latin America. Grounded on the natural resources-based view theory, this study assessed the effects of environmental collaboration on five dimensions of environmental performance (greenhouse gas emissions, energy efficiency, food loss and waste, food quality and safety, and water footprint management) in agri-food companies with a survey with Chilean firms. Data were analyzed using the partial least square—structural equation modeling. We found that international orientation positively influences all five dimensions of environmental performance. Our study identified that the dimension most impacted by international orientation is water footprint management, and the least impacted is food quality and safety. With the aid of multi-group analysis, we concluded that there are no significant differences in these relationships between micro/small and medium/large companies. A significant difference was observed in food loss and waste between fruit and nonfruit producers. We expect the outcomes of this study will support exporting-related decisions and public policies in Latin America.

像其他拉丁美洲经济体一样,智利在国际农业市场上的存在显著增加。农产品主要由专业出口商或跨国企业开发,并出口到几个不同的国家。在智利,水果部门几乎占出口总额的一半。面向国际的公司在国外市场开拓商机,在国际经营中投入充足的资源。此外,由于外部压力,更多面向国际的公司可能更倾向于投资绿色实践,从而实现更高的环境绩效。在这方面,环境绩效与在农产品生产、运输和消费过程中保护现有自然资源的程度有关。据我们所知,有零星的证据表明国际导向和农业食品公司的环境绩效之间的关系,特别是在拉丁美洲。本研究以自然资源为基础的观点理论为基础,通过对智利公司的调查,评估了环境合作对农业食品公司环境绩效的五个维度(温室气体排放、能源效率、粮食损失和浪费、食品质量和安全以及水足迹管理)的影响。采用偏最小二乘结构方程模型对数据进行分析。我们发现国际化取向对环境绩效的五个维度都有积极影响。我们的研究发现,受国际化影响最大的维度是水足迹管理,受影响最小的维度是食品质量和安全。通过多组分析,我们得出结论:中小微企业和大中型企业在这些关系上没有显著差异。在水果和非水果生产者之间观察到食物损失和浪费的显著差异。我们期望这项研究的结果将为拉丁美洲的出口相关决策和公共政策提供支持。

This study combines sensory analysis and stated preference valuation techniques to assess the monetary value of organoleptic attributes of new tomato varieties. The tomatoes evaluated included two new varieties adapted to South Texas growing conditions, a commercial check, and tomatoes imported from Mexico. In a blind sensory test, participants sampled, rated, and valued the attributes of all tomato varieties. Willingness to pay responses were collected using a payment card elicitation approach and jointly analyzed with a multivariate ordered probit model. Price premiums were associated with males, smaller households, younger consumers, higher income, and the liking of different organoleptic attributes.

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.
在亚马逊的全球市场上,多个卖家销售同一种产品,因此亚马逊推出了 BuyBox。这种类似盒子的功能位于产品页面的右上角,在特定时间内突出显示单个卖家。我们的研究利用选择模型和来自五个国家超过 29 万种独特杂货产品的面板数据集,调查了影响 BuyBox 分配的关键因素。我们发现,赢得 BuyBox 主要取决于有竞争力的定价--在 180 天内成为价格最低的卖家能显著提高获得 BuyBox 分配的机会。此外,保持较低的当前产品价格、较低的销售排名和最低的缺货率也是成为 BuyBox 卖家的关键。这些发现对亚马逊及其由 200 多万第三方卖家组成的庞大网络产生了影响,这些卖家在竞争日趋激烈、充满活力的电子商务领域中游刃有余。

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.
本研究旨在评估巴西牧场替代牛奶生产系统的技术效率差异。我们利用 2014 年至 2021 年的面板数据(对 383 个奶牛场的 1117 个观测值),比较了最近采用的堆肥垫式挤奶牛舍(CPB)与半圈养(SC)和非结构化圈养(UNS)系统的技术效率。采用广义真实随机效应估算随机前沿,以评估技术效率与所采用的生产系统之间的关系,将效率分解为瞬时(短期)和持久(长期)两部分,并控制未观察到的异质性。我们发现,采用封闭系统的农场比采用半封闭系统的农场效率更高。将总体技术效率分解为持续和瞬时两个部分表明,农民在应对短期冲击时比决定使用哪种系统时更有效率。使用 CPB 等资本密集型技术可为提高巴西奶牛场的盈利能力和生产率增长提供机会。

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.

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.

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].
本研究探讨了农业用地市场的租金价格比,这对评估市场效率、政策需求和农民决策至关重要。传统上,由于缺乏同一块土地的同期销售和租金数据,分析面临挑战,可能导致结果偏差。本研究利用德国东部的独特数据集,涵盖了 2016 年至 2019 年的拍卖数据,从而避免了这一问题。该数据集与众不同,包含了单个农户在一个点上对同一块农用地的购买和租赁价格报价。因此,本研究克服了使用汇总数据或非同期数据的传统局限性。因此,研究的重点在于揭示个体租金价格比与众多影响因素(包括土地特征和当地农业结构)之间错综复杂的关系。使用位置、形状和规模的广义加性模型为这一分析提供了一个稳健的框架,使人们对单个租金价格比的分布特性有了细致入微的了解。这项研究提供了有力的经验证据,突出表明如果决策者坚持干预农业用地市场,就需要制定适应性政策和针对特定地区的政策。此外,研究还为今后的研究确定了有前景的出发点。[经济学引文:Q15]。
