    OriginalMy: Blockchain technology and business defying a 20th-century regulation
    (2020) Moraes, Trícia Karla Lacerda; Cernev, Adrian Kemmer
    Blockchain 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 Barbaceia
    Purpose – 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.
