Economia circular e a aplicação de seus indicadores no setor energético brasileiro
(2020) Santos, Rafael De Vitto
O mundo está em constante transformação e nossos hábitos e padrões de consumo não apenas norteiam essas mudanças, como também ajudam a definir o caminho que possivelmente trilharemos desse momento em diante. Tendo isso em vista, o presente trabalho tem como intuito entender o conceito de Economia Circular, levantar algumas das iniciativas em prática no setor energético brasileiro e entender se indicadores encontrados na literatura atual são adequados para medir o “nível de circularidade” dessas iniciativas, através de um entendimento de suas lógicas, cálculos e dados utilizados. Foi realizada uma análise descritiva sobre 3 tipos de indicadores discutidos na literatura atual, com 3 níveis de escopo diferentes: micro meso e macro (Harris et. al, 2020). Os indicadores selecionado variam entre indicadores materiais, sistemas de múltiplos indicadores e indicadores sociais. Ao final dessa análise esse trabalho conclui que alguns dos indicadores de circularidade mais conhecidos não são compatíveis com as iniciativas desenvolvidas nesse setor específico. Outros indicadores não tão usuais já podem ser considerados mais próximos de um nível adequado, mas no entendimento desse artigo, ainda necessitam de alguns ajustes para serem de fato ideais.
Latin America: Public management concepts and developments
(2022) MARCELO MARCHESINI DA COSTA; BRUNO VARELLA MIRANDA
The evolution of public administration in Latin America since the early 20th century can be described as successive attempts of modernization and adaptation to new political and socioeconomic circumstances. Much of the push for these reforms has come either from international inspirations – e.g., the “progressive movement” in the United States and the “New Public Management” arrangements – or from episodes of institutional change, which are common in a region marked by successive cycles of democratic, dictatorial, and populist regimes. Yet by the second decade of the 21st century, these multiple waves of transformation have not entirely revamped practices which are deeply embedded in the public administration of Latin American countries, such as patrimonialism, the existence of a bureaucratic culture that inhibits innovation at the public management level, and the high level of centralization in the decision-making process.
ESG: disentangling the governance pillar

Alternative proteins: organization of the agri-food system and sustainability outcomes
(2023) BRUNO VARELLA MIRANDA; VINICIUS PICANÇO RODRIGUES
Everybody is talking about alternative proteins. And yet, we do not know much about the socioeconomic implications of the emergence and consolidation of the alternative proteins market. In part, the gap in our knowledge is justifiable: alternative proteins represent a tiny slice of the market, and some of the most expected technological breakthroughs are still to materialize. On the other hand, the mere interest in the alternative proteins industry is a powerful driver of economic, environmental, and social changes which may deeply affect the future of traditional agriculture. Helping to shed light on this emerging industry, we discuss the relationship between the development of an alternative proteins market and sustainability outcomes in the economic, environmental, and social areas. We adopt a governance perspective, discussing first on the relationships among the many players within the alternative proteins agri-food system and then on the interactions in the broader competitive and institutional environment. We are particularly interested in outlining potential friction points and insights for research hypotheses

Assessing the performance of voluntary environmental agreements under high monitoring costs: Evidence from the Brazilian Amazon
(2023) BRUNO VARELLA MIRANDA; Oliveira, Gustavo Magalhães de
Voluntary environmental arrangements generally coexist with State-based and private rules, creating a property rights system that legitimizes certain behaviors. In a world of positive transaction costs, legitimacy ensues from imperfect monitoring activities, opening room for opportunism. In this paper, we discuss how the existence of multiple rules in a scenario of high monitoring costs affects the performance of an environmental policy. We discuss the case of deferred prosecution agreements (TAC, acronym in Portuguese), which are voluntary arrangements designed with the goal of incentivizing slaughterhouses to monitor the environmental practices of ranchers in the Brazilian Amazon. More specifically, we study how the signature of a TAC agreement affects deforestation rates in the Brazilian Amazônia Legal region at the municipality level. This paper adopts a difference-in-differences approach to analyze a sample of Brazilian municipalities between 2006 and 2017. Our results, which remain robust across alternative estimators and subsamples, show that the signature of a TAC agreement increases deforestation rates by 0.2 standard deviations. We argue that the signature of a TAC agreement, by creating an imperfect proxy for “good behavior” that enables both compliant and non-compliant organizations to access credit, may incentivize deforestation in the Brazilian Amazon.
Determinantes do desmatamento na Amazônia Legal: uma análise exploratória
(2020) Fabris, Felipe Nakano
A Amazônia Legal é uma região brasileira que está em constante debate mudança. Sua utilização como recurso econômico vem ocorrendo desde os anos 60 e hoje, tem como principal driver de seu desmatamento a agropecuária. Nesse artigo será investigado como esse e os demais determinantes do desflorestamento, como a agricultura e o extrativismo vegetal, agem no período de 2001 até 2018. Observando e controlando por fatores institucionais e econômicos que possam influenciar no desmatamento dos municípios da Amazônia Legal, mas tendo em foco a produção pecuária, a extração de madeira e as culturas de Soja, Milho e Cana de Açúcar e seus rendimentos. Foi realizada a análise de uma matriz de correlação, aliada à uma regressão com dados em painel do período explicitado, a nível de município. Tendo em mente a robustez do modelo no processo, foi concluído que de fato a criação de gado é o que mais contribui para o desmatamento na Amazônia Legal, assim como confirmada a relevância da produção de soja para o desflorestamento sendo o segundo principal driver.
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.
