Purpose: The purpose of this paper is to investigate information asymmetry in cattle supply transaction in Brazil. While the literature traditionally explores the seller’s information asymmetry advantages, the authors, in turn, draw attention to buyer’s role. This paper aims to show what farmer characteristics present negative correlation with slaughterhouses’ information asymmetry advantages. By slaughterhouses’ advantages, the authors refer to slaughterhouses’ opportunistic appropriation of value due to hidden information, such as quality measurement and remuneration of difficult-to-measure attributes. In doing so, this paper addresses the following research question: what are the farmer’s characteristics with negative correlation with slaughterhouses’ information asymmetry advantages? Design/methodology/approach: This paper employs a logit model regression on a survey of 89 Brazilian cattle breeders. Drawing on transaction cost economics, this study empirically evaluates farmers’ technology level, level of education, family tradition, farm size and efforts to collect price information, to test which of these characteristics present negative correlation with slaughterhouses’ information asymmetry advantages. Findings: The results illustrate that the cattle breeders’ level of education is negatively correlated with buyers’ information asymmetry advantages. Additionally, the authors find a controversial result presenting efforts to collect price information as positively correlated with this kind of information asymmetry advantages. Farmer’s farm size, family tradition and the level of technology were not influential. These findings suggest that a possible value appropriation from buyers’ information asymmetry is a problem for several types of producers, even varying size, family tradition in the activity or transaction costs to collect price information (e.g. lack of transparency). Initiatives should try to reduce this problem to these farmers to avoid value appropriation resulting from information asymmetry problems, especially in the lack of transparency. Originality/value: This paper adopts a survey about information asymmetry in cattle supply transactions in Brazil, which is well known as one of the most relevant producer and consumer of meat. The main contribution is to shed light on the understanding of buyers’ information asymmetry advantages in farmer-slaughterhouse transactions to avoid potential conflicts. Given some singularities of the Brazilian cattle industry, the authors can empirically test buyers’, not sellers’, information asymmetry advantages.

O papel das instituições formais e informais na economia das organizações é tradicionalmente analisado em termos dos mecanismos eficientes de governança que minimizam os custos de transação. Baseada numa perspectiva inversa, a presente pesquisa foca nas falhas de coordenação e no problema da falta de garantias nas transações econômicas. Especificamente, examina-se o conjunto de garantias que suportam a transação entre pecuaristas e a indústria frigorífica em Mato Grosso do Sul com foco nas ineficiências do processo de comercialização de gado para abate. Para a compreensão das falhas de coordenação, propõe-se um constructo teórico baseado em Barzel (1997), que relaciona direitos de propriedade, garantias e instituições. Esse modelo é testado empiricamente por meio do desenvolvimento de duas regressões logísticas múltiplas: i) modelo logit ordenado baseado na percepção de risco dos pecuaristas e ii) modelo probit bivariado recursivo baseado na percepção de risco dos pecuaristas e no papel das ações coletivas. Os resultados apontam para a importância das instituições formais e das ações coletivas como mecanismos geradores de garantias para a transação e, consequentemente, para a minimização dos custos de transação.

This systematic review aims to synthesize evidence on zoonotic agents in farmed fish from the interdisciplinary One Health perspective. The review followed a protocol, following the PICOS strategy, where P represents population (farmed fish), I represents intervention (fish diseases), C represents comparison (healthy fish), O represents outcome (One Health) and S represents the type of study (experimental studies). The searches were conducted in the SCOPUS, Science Direct and PubMed Central databases. Of the 400 articles identified, 23 met the inclusion criteria due to their methodological robustness. These articles focused predominantly on parasitic (60.9%) and bacterial (39.1%) zoonotic agents. The One Health approaches discussed throughout the articles included host-parasite interactions (35%), antimicrobial resistance (22%), infections and food safety (18%), nutrition and immune responses (17%), stress and immune responses (4%) and anthelmintic testing (4%). The findings indicate that high-level scientific production is often confined to specific fields, such as veterinary medicine, biological sciences and animal science/fishery resources. There is a lack of broad interdisciplinary collaboration, limiting the integration of diverse fields to improve scientific production.

This study focuses on examining the relationship between corporate governance practices and the performance of agricultural co-operatives in Mato Grosso do Sul, Brazil. The primary objective is to address agency conflicts within co-operatives by investigating the extent to which corporate governance practices align the interests of co-operatives and their members. The research approach involved a document analysis using the bylaws and meeting minutes of 21 co-operatives, totaling 84 documents. The assessment of corporate governance levels was based on a comparison with the 40 recommendations proposed by the Brazilian Co-operatives Organization (OCB, 2016), categorized into five major areas. The study is grounded in agency theory, particularly focusing on monitoring and incentives as key aspects. The findings reveal that the majority of recommended governance practices are concentrated in the "management board" area, while the co-operatives' most adopted practices are related to the "members and general assembly" dimension, which primarily involves monitoring efforts. However, when considering the full set of OCB's recommendations, only two were fully implemented by the co-operatives. These results indicate a low level of corporate governance in agricultural co-operatives in Mato Grosso do Sul.

We examine the role of collective actions as supporting elements of a long-lasting sustainable food supply chain. This article’s main contribution is to link the idea of sustainable supply chains and the collective action problem (horizontal coordination) that may be required in order to deal with externalities related to the provision of sustainable products. In addition, we analyze how the presence or absence of government incentives shapes collective action in the food industry. We base our analysis in a simple formal argument inspired by case studies regarding sustainable farming in Brazil and the Netherlands. Results show that horizontal mechanisms of cooperation maintain positive levels of sustainability, even in the absence of direct payments by the government.
