Artigo Científico Análise dos determinantes do desempenho industrial: o caso do setor de higiene pessoal, perfumaria e cosméticos no Brasil no período 2001-2013(2022) ADRIANA BRUSCATO BORTOLUZZO; Valfré, Livia Amaral; GUILHERME FOWLER DE AVILA MONTEIRODurante o período 2001 a 2013, o setor de higiene pessoal, perfumaria e cosméticos (HPPC) apresentou-se como um dos mais dinâmicos da economia brasileira. O setor atingiu níveis de crescimento médio real próximo a 10% ao ano (a.a.), ultrapassando a evolução média da indústria em geral (2,2% a.a.) e o crescimento médio do produto interno bruto – PIB (3,0% a.a.). Diante desse extraordinário desempenho, investigamos os determinantes macroeconômicos e demográficos da expansão desse setor. Para tanto, estimamos regressões com dados em painel tendo como referência as vendas anuais de um conjunto específico de produtos. A conclusão é que as variáveis mais importantes para explicar as vendas do setor de HPPC são a taxa de inflação e a taxa de juros, em combinação com a renda e o nível de desemprego.Artigo Científico Management of corporate debt deadlines: A look at publicly traded companies in Brazil(2023) Santos, João Daniel Azevedo dos; ADRIANA BRUSCATO BORTOLUZZO; Gonçalves, Adalto BarbaceiaThis study investigates the maturity structure of listed non-financial Brazilian companies from 2010 to 2019 and reveals that these companies do not spread their debt maturities upon renewal, unlike the results observed by Choi et al. (2018) for US firms. Even after the rollover shock in 2015 where the Brazilian sovereign debt’s investment were downgraded, these firms did not increase the maturity spread of their debt. In addition, the research evaluated corporate debt management by utilizing Brazil’s downgrade as a “quasi-natural experiment” in the exogenous shock model. The results indicate that Brazilian companies may face considerable debt rollover risks due to the concentration of maturities in specific maturity ranges during future credit shocks. Proper control of financing structures is crucial to ensure that companies remain resilient and do not have to turn down profitable investments or high-quality assets during financial crises. This research has significant implications for corporate practice and the associated risks of financing profitable projects, particularly in countries with less efficient capital markets.Artigo Científico Technological Adoption: The Case of PIX in Brazil(2024) Gabriel Bernardes Amboage; GUILHERME FOWLER DE AVILA MONTEIRO; ADRIANA BRUSCATO BORTOLUZZOPurpose This study investigates the primary determinants of consumers' intention to adopt PIX as a payment method in Brazil, as well as their actual usage behavior. Design/methodology/approach The study employs the Unified Theory of Acceptance and Use of Technology (UTAUT) to analyze both the intention to use and the actual period of use of PIX technology as a measure of practical usage. With this approach, researchers can determine whether people’s intention to use PIX translates into a higher rate of technology adoption and effective and sustained usage. The study collected data from 659 consumers across Brazil through a questionnaire and used structural equation analysis to analyze the data. Findings Research suggests that the intention to adopt PIX as a payment method is mainly determined by the perceived value, performance expectancy, and the habit of using mobile internet. Positive associations are also confirmed between adoption intention, the effective usage time of PIX, and the habit of using mobile internet in conjunction with PIX use. Originality/value The study’s uniqueness stems from its focus on the PIX usage, which is becoming the primary payment method in Brazil. It also measures the practical usage of the technology by examining the duration of user experience. This enables the assessment of whether the intention to use PIX effectively translates into a higher speed of technology adoption.Artigo Científico Capital structure determinants of private and public firms in an emerging economy: a panel data quantile regression analysis(2024) ADRIANA BRUSCATO BORTOLUZZO; Sanvicente, Antonio Zoratto; Bortoluzzo, Maurício MesquitaPurpose This study explores distinct capital structure patterns between private and public companies, examining the varying influence of determinants on debt choices contingent upon a firm’s existing debt position. Design/methodology/approach Employing annual data from 2012 to 2022 for 142 public firms and 660 private firms in a large emerging economy, we use quantile regression within a panel data framework to study the heterogeneous effects of debt determinants, incorporating firm and time random effects. Findings Our findings indicate that such factors as size and operating margin contribute to higher levels of debt, while investment opportunities reduce the debt level. Further analyses, when accounting for a firm’s likelihood of being publicly traded, reveal that dividend payout and operating margin significantly influence debt levels, exclusively in the presence of high debt proportions. Conversely, investment opportunities emerge as a substantial determinant in all debt scenarios. In addition, we found a strong persistence in the indebtedness of companies, and we conclude that the effect of the determinants of indebtedness is heterogeneous according to the level of debt of companies. Originality/value This research provides a comprehensive comparison between private and public firms, not only in terms of debt levels but also in key capital structure determinants, highlighting their significance within the context of varying debt levels.Artigo Científico Determinant factors of banking proftability: an application of quantile regression for panel data(2024) ADRIANA BRUSCATO BORTOLUZZO; Ciganda, Rodrigo Ricardo; Bortoluzzo, Mauricio MesquitaThis study examines the determinants of bank proftability using a quantile regression approach, ofering insights into factors afecting banks across diferent percentiles of proftability. Utilizing a comprehensive database from Orbis covering 1200 top-market institutions across 101 countries, the research uniquely employs dynamic panel quantile regression while addressing sample survival bias. Our fndings highlight that bank size and capital adequacy nega tively impact proftability, whereas market value exerts a positive infuence on higher proftability banks. Credit risk afects proftability diferently across levels of proftability, and infation rate shows signifcance only for higher proft ability banks. The study contributes to the existing literature by ofering valuable insights into the factors determining bank proftability and how they behave at diferent percentiles in the sample, suggesting the importance of bank efciency and competition in promoting economic growth- 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.
- Gestão dos prazos da dívida corporativa: um olhar para as empresas de capital aberto no Brasil(2023) Santos, João Daniel Azevedo dos; ADRIANA BRUSCATO BORTOLUZZO; Gonçalves, Adalto BarbaceiaEste estudo investiga a estrutura de vencimento da dívida de 275 empresas abertas não financeiras brasileiras de 2010 a 2019. Os resultados mostram que essas empresas não dispersam seus vencimentos de dívida na renovação, ao contrário do observado por Choi et al. (2018) para empresas dos Estados Unidos. Mesmo após o choque de rolagem da dívida depois da perda do grau de investimento da dívida soberana brasileira em 2015, essas empresas não aumentaram a dispersão de vencimentos. Ao utilizar a perda do grau de investimento do Brasil como um "experimento quase-natural" no modelo de choque de crédito, o presente estudo avalia a gestão da dívida corporativa. Os resultados indicam que as empresas brasileiras podem enfrentar consideráveis riscos de rolagem da dívida devido à concentração de vencimentos em faixas específicas durante futuros choques de crédito. O controle adequado das estruturas de financiamento é crucial para garantir que as empresas permaneçam resilientes e não precisem recusar investimentos lucrativos ou ativos de alta qualidade durante crises financeiras. Esta pesquisa tem implicações significativas para a prática corporativa e os riscos associados ao financiamento de projetos lucrativos, particularmente em países com mercados de capitais menos eficientes.
- Multichannel relational communication strategy: does one-sized strategy fit all customers?(2024) CARLA SOFIA DIAS MOREIRA RAMOS; ADRIANA BRUSCATO BORTOLUZZO; DANNY PIMENTEL CLAROThis study aims to capture how the association between a multichannel relational communication strategy (MRCS) and customer performance is contingent upon such customer performance (low- versus high-performance customers) and to reconcile past contradictory results in this marketing-related topic. To this end, the authors propose and validate the method of quantile regression as an unconventional, yet effective, means to proceed to that reconciliation.
