Artigo Científico Combining Ad Libraries with Fact Checking to Increase Transparency of Misinformation(2021) IVAR ALBERTO GLASHERSTER MARTINS LANGE HARTMANNArtigo Científico Climate Security, the Amazon, and the Responsibility to Protect(2021) Macedo, GustavoIn this article, I briefly present the multilateral discussion on ‘climate security’ and its relation to the protection of the Amazon. First, the text points out the importance of the Amazon for keeping global climate balance, the drastic change to the environmental agenda of Brazilian diplomacy, and the growing call in international public opinion for an internationally coordinated action to reverse deforestation in the region. Next, it introduces the concept of ‘climate security’, its development within the United Nations Security Council, and its relation to the principle of responsibility to protect (R2P). Finally, based on contextual evidence, I carry out a prospective analysis of the narratives that might be constructed to justify applying this principle to the Brazilian Amazon.Artigo Científico Do Formalist Judges Abide By Their Abstract Principles? A Two-Country Study in Adjudication(2021) Bystranowski, Piotr; Janik, Bartosz; Próchnicki, Maciej; Hannikainen, Ivar Rodriguez; GUILHERME DA FRANCA COUTO FERNANDES DE ALMEIDA; Struchiner, NoelRecent literature in experimental philosophy has postulated the existence of the abstract/concrete paradox (ACP): the tendency to activate inconsistent intuitions (and generate inconsistent judgment) depending on whether a problem to be analyzed is framed in abstract terms or is described as a concrete case. One recent study supports the thesis that this effect influences judicial decision-making, including decision-making by professional judges, in areas such as interpretation of constitutional principles and application of clear-cut rules. Here, following the existing literature in legal theory, we argue that the susceptibility to such an effect might depend on whether decision-makers operate in a legal system characterized by the formalist or particularist approach to legal interpretation, with formalist systems being less susceptible to the effect. To test this hypothesis, we compare the results of experimental studies on ACP run on samples from two countries differing in legal culture: Poland and Brazil. The lack of significant differences between those results (also for professional legal decision-makers) suggests that ACP is a robust effect in the legal context.Artigo Científico Are There Cross-Cultural Legal Principles? Modal Reasoning Uncovers Procedural Constraints on Law(2021) Tobia, Kevin P.; GUILHERME DA FRANCA COUTO FERNANDES DE ALMEIDA; Donelson, Raff; Dranseika, Vilius; Kneer, Markus; Strohmaier, Niek; Bystranowski, Piotr; Dolinina, Kristina; Janik, Bartosz; Keo, Sothie; Lauraityt, Egle; Liefgreen, Alice; Próchnicki, Maciej; Rosas, Alejandro; Hannikainen, Ivar R.Despite pervasive variation in the content of laws, legal theorists and anthropologists have arguedthat laws share certain abstract features and even speculated that law may be a human universal. Inthe present report, we evaluate this thesis through an experiment administered in 11 different coun-tries. Are there cross-cultural principles of law? In a between-subjects design, participants (N = 3,054)were asked whether there could be laws that violate certain procedural principles (e.g., laws applied retrospectively or unintelligible laws), and also whether there are any such laws. Confirming our pre-registered prediction, people reported that such laws cannot exist, but also (paradoxically) that there aresuch laws. These results document cross-culturally and –linguistically robust beliefs about the conceptof law which defy people’s grasp of how legal systems function in practice.Artigo Científico Capitalizing on Green Debt: A World-Ecology Analysis of Green Bonds in the Brazilian Forestry Sector(2021) Ferrando, Tomaso; GABRIELA DE OLIVEIRA JUNQUEIRA; Vecchione-Gonçalves, Marcela; Imola, Iagê; Prol, Flávio Marques; Herrera, HectorGreen bonds represent an increasingly popular way to match “environmental sustainability,” growth, and the aspirations of global financial capital. In this article, we leverage a world-ecology approach to unpack and make sense of green bonds as public/private constructions that shape and subordinate the complex ecologies of territories to the needs of finance and reproduce the global patterns of uneven development and capitalist accumulation. Through the study of recent green bond issuances realized by private companies active in the forestry sector in Brazil, we discuss how green bonds as a “new” form of “green” debt put nature at work and transform the territories and natural elements in the global south into “temporal and spatial fixes” for the needs of global financial capital.- An Overview on the Brazilian Digital Payment System: Legal, Business and Technological Aspects(2021) Novaes, André Luiz Farias; IVAR ALBERTO GLASHERSTER MARTINS LANGE HARTMANNhe adoption of new, digital payment methods brings significant benefits to customers and society such as improved efficiency, greater competition, broader financial inclusion, and more innovation, according to IMF in Digital Currencies: The Rise of Stablecoins, 2019. The digital payment market is a $3 trillion industry, corresponding to 13% of total commerce, and will more than double by 2022, informs the McKinsey report Global payments 2018: A dynamic industry continues to break new ground, 2018. Although it is a prospective market, the Digital Payment System is not an intensive research topic, with a literature still in an embryonic stage. Even more: it does not completely capture the real movement on digital payments systems happening worldwide. Through an extensive but not exhaustive overview on the Brazilian digital payment system, this paper aims to develop the literature on the field, focused on the legal, business and technology fronts; to partially fulfil the gap between market and academia, through a comprehensive analysis on usual KPIs and descriptive statistics on digital payment systems, establishing a parallel with recent literature; and, finally, to describe challenges and opportunities for development in the Digital Payment System both in market and academia.
- OriginalMy: Blockchain technology and business defying a 20th-century regulation(2020) Moraes, Trícia Karla Lacerda; Cernev, Adrian KemmerBlockchain is the century’s most notable technological innovation that is reshaping all industries. Notwithstanding, the technology needs to achieve maturity and address critical problems to generate real business value. Consequently, blockchain-based new ventures have been dealing with high-technology-associated pressures to enter this modern market. Most of them are still in the platform proliferation stage, struggling to face serious regulation challenges. Alternatively, there are successful cases in which wise strategic choices allowed companies to overcome the challenges and leverage their business successfully – OriginalMy is one of them. It is a Brazilian born blockchain-based venture aiming to decentralise notary and authenticity contributing to reduce excessive bureaucracy and eventually restrain corruption that is relatively common not only in their country but all over the world. This Teaching Case covers how the venture strove against unpredictable and unfavourable situations to fund and develop its blockchain business. It is supplemented by in-depth Teaching Notes where we craft a synthesised theoretical background to support the complex decision-making process through which the Chief Executive Officer defined the company’s fate amid such challenges and uncertainties concerning blockchain technology. The case examines the entrepreneurs behind OriginalMy, its growth, the difficulties it has faced, the upright issues surrounding it and its future outlooks. It draws on theory from high-technology market entry and the inherent pressures of this kind of entrepreneurship, sustained by the strategies and alliances that entrepreneurs can enact to address them.

- Rating changes and the impact on stock prices(2020) Baraccat, Bruno Borges; ADRIANA BRUSCATO BORTOLUZZO; Gonçalves, Adalto BarbaceiaPurpose – The objective of this study is to analyze the impact of changes in credit ratings on the long-term return of Brazilian firms. Design/methodology/approach – We conducted an event study to measure how stock prices in the Brazilian stock exchange (B3) react to rating upgrades and downgrades by Moody’s and S&P. Findings – Our sample presents positive and significant returns measured by the BHAR for ratings downgrades and non-significant ones for upgrades. Our data also show the important role of the previous rating in explaining these results in a non-linear fashion. Originality/value – Our research makes an important contribution to the theory of market efficiency, analyzing the degree of information present in the announcements of credit ratings changes. We also present results for Brazilian companies, correcting gaps pointed out in previous methodologies.
