Voting with the wallet: a principal-agent framework for the analysis of sustainable supply chains
(2024) BRUNO VARELLA MIRANDA; GUILHERME FOWLER DE AVILA MONTEIRO; Oliveira, Gustavo Magalhães de; VINICIUS PICANÇO RODRIGUES
Purpose – This paper aims to investigate delegation decisions in supply chains, exploring the metaphor that consumers who make environmentally and socially responsible choices are equivalent to voters in an election. Design/methodology/approach – This theoretical paper relies on the principles of agency theory to shed light on fundamental challenges that shape our ability to transform supply chains. Findings – This paper unravels two puzzles linked to delegation decisions within sustainable supply chains. It shows that as firms adopt sustainable production systems, their ability to convey relevant information that convinces consumers to enter in a delegation relationship diminishes, ceteris paribus; and once a delegation relationship is established, complementarity within the dimensions of the contract is necessary to guarantee the delivery of sustainability attributes. Research limitations/implications – The findings of this paper offer insights that can inspire empirical research on sustainable supply chain management. Practical implications – Policymakers and entrepreneurs willing to incentivize the transformation of supply chains must think about the nature of the relationship between firms and consumers. This paper provides a metaphor that can help practitioners to reinterpret their role as providers or consumers of products and services with sustainability attributes. Social implications – This paper provides insights that may enhance the understanding of how individual consumption decisions may contribute to transforming supply chains. Originality/value – This paper expands the repertoire of theoretical tools that can be applied to study the emergence and resilience of sustainable supply chains.
Compromissos Mútuos Nas Transações De Hortícolas Na Serra Fluminense
(2019) Mozambani, Carlos Ivan; Souza Filho, Hildo Meirelles De; BRUNO VARELLA MIRANDA
O objetivo deste artigo é identificar os fatores que explicam o estabelecimento de compromissos mútuos entre os agricultores familiares e compradores de produtos hortícolas na Região Serrana do Rio de Janeiro. Para tanto, analisa 567 transações referentes a uma amostra de agricultores familiares baseados em sete municípios. A Economia dos Custos de Transação (ECT) é usada como marco teórico. O estudo empírico parte da construção de uma variável que divide as transações em dois grupos. No primeiro grupo, intitulado "com compromisso", o comprador fornece insumos ou assistência técnica ao produtor. Já no segundo grupo, intitulado "sem compromisso", inexiste tal comprometimento de conhecimento e recursos. Estatísticas descritivas e um modelo logístico (logit) binário mostram que transações "com compromisso" se caracterizam por um maior nível de especificidade do ativo e um amplo conjunto de rotinas de coordenação. Por sua vez, a construção de confiança emerge como um mecanismo de coordenação fundamental mesmo naquelas transações "sem compromisso".

How do transaction costs, capabilities and networks influence the procurement strategies of small agri-food firms? Evidence from the wine industry
(2022) BRUNO VARELLA MIRANDA; Ross, Brent; Franken, Jason; Gómez, Miguel
Purpose – The purpose of this study is to disentangle the drivers of adoption of procurement strategies in situations where small agri-food firms deal with constrained organizational choices. More specifically, the authors investigate the role of transaction costs, capabilities and networks in the definition of feasible “make or-buy” choices in emerging wine regions. Design/methodology/approach – This article analyzes a unique dataset of small wineries from five US states: Illinois, Michigan, Missouri, New York and Vermont. The reported results derive from both a hurdle model (i.e. a probit model and a truncated regression model) and a tobit model. Findings – The results suggest the importance of trust as a replacement for formal governance structures whenever small firms deal with highly constrained sets of organizational choices. On the other hand, the level of dependence on a limited mix of winegrape varieties and the perception that these varieties are fundamental in building legitimacy help to explain higher rates of vertical integration. Originality/value – This study is important because it sheds light on organizational constraints that affect millions of farmers across the globe. The study of “make-or-buy” decisions in agri-food supply chains has mostly relied on the implicit assumption that all organizational choices are available to every firm. Nevertheless, limited capabilities and the participation in low-density networks may constrain the ability of a firm to adopt a governance mechanism. Stated organizational preferences and actual organizational choices may thus differ.
Plural forms and differentiation strategies in the agri-food sector: Evidence from the U.S. wine industry
(2022) BRUNO VARELLA MIRANDA; Ross, Brent; Franken, Jason; Gómez, Miguel
This article investigates how measurement ability, trust, and the pursuit of differentiation strategies influence the adoption of plural forms in an agri-food system. We analyze a unique dataset of 314 winegrape sourcing choices from 74 wineries located in five U.S. states, investigating how the pursuit of differentiation influences the likelihood of adoption of a plural form—that is, the simultaneous adoption of a formal arrangement (i.e., vertical integration or long-term formal contract) and an informal arrangement (i.e., informal contracts or spot-market transactions). Consistent with previous studies, measurement ability and the existence of trust are both associated with a higher likelihood of adoption of informal arrangements in comparison to formal arrangements. Moreover, we show that the likelihood of adoption of a plural form increases as the differentiation potential of a winegrape variety also increases. Finally, we find that the use of plural forms is associated with a reduction in the importance of trust in the relationships with external suppliers. This study is important because it sheds light on the role of plural forms in the pursuit of competitive advantage in an agri-food system. Overall, it suggests that the current interpretations of the idea of “vertical coordination” may be enlarged to encompass a greater deal of organizational diversity.

Disentangling the role of the institutional environment in the ownership competence framework: A comment on Foss et al. (2021)
(2023) GUILHERME FOWLER DE AVILA MONTEIRO; BRUNO VARELLA MIRANDA
Research Summary: We extend the ownership com petence framework by discussing how the features of the institutional environment influence the exercise of ownership competence. Two amendments are pro posed. First, we add a new dimension to the frame work, institutional competence (“where to own”), which denotes that individuals and firms have heterogeneous abilities to assess how an institutional environment affects the potential uses of a resource. Second, we argue that institutional uncertainty moderates the three original dimensions of the framework, impairing the exercise of ownership competence of some entrepre neurs and firms more than of others. We use examples from the literature to illustrate our arguments. We also discuss the implications of our analysis. Managerial Summary: The ownership competence framework is built on the idea that business owners have different abilities to deploy resources and create value. Starting from this contribution, we shed light on the specific role that the institutional environment plays in the exercise of ownership competence. We argue that the ownership competence framework must explicitly consider where ownership takes place in order to explain the actions of entrepreneurs and firms. We also claim that institutional uncertainty can influence value creation in more subtle ways than indicated in the original formulation of the ownership competenceframework. All in all, this article paves the way forinstitutional aspects to be considered more explicitly inthe strategic analysis of ownership.
