Corrupção, Petrobrás, Cadeia de Suprimentos, Retornos Anormais, Efeito ContágioResumo
Objetivo: analisar o efeito contágio nos ativos das empresas da cadeia de suprimentos da Petrobras diante dos escândalos de corrupção abrangidos pela Operação Lava-Jato.
Método: foi realizado estudo de eventos com 60 ativos que compõem o S&P500 sendo definidas duas datas para a análise.
Originalidade/Relevância: o estudo fornece evidências de que as condutas dos diferentes parceiros da cadeia de suprimentos devem figurar como uma preocupação dos gestores e dos órgãos reguladores, bem como reforça a prerrogativa de que o mercado acionário busca antecipar notícias e, por vezes, realizar movimentos anormais punindo ativos de organizações que se relacionam com empresas supostamente vinculadas a condutas ilícitas.
Resultados: os retornos identificados foram anormais negativos e significantes para a cadeia de valor.
Contribuições Teóricas/Metodológicas: os efeitos identificados apontam que a corrupção causa oscilações anormais no mercado de ações para aqueles que fornecem suprimentos para empresas envolvidas em escândalos de corrupção.
