Party competition under dictatorships: evidence from congressional speech in Brazil
Keywords in English

Party competition
Abstract in English
This paper examines the role of political competition and emotional rhetoric on congressional discourse during the Brazilian military dictatorship era. Leveraging historical archives of Congressional records, we curated a comprehensive database of parliamentary speeches from 1975 to 1986. Specifically, our analysis explores an exogenous political reform that increased party competition within the opposition during the redemocratization phase under the military regime. By combining theoretical frameworks drawn from the party competition literature with newly developed Natural Language Processing (NLP) techniques, our findings unveil a significant increase in the primary opposition partys use of predominantly negative emotional rhetoric. These results highlight the impact of political competition on nonpolicy attributes in party strategies and demonstrate how NLP methods can be integrated with models of party competition to study political speech.

Abstract in Portuguese
Este artigo examina o papel da competição política e da retórica emocional no discurso parlamentar durante a era da ditadura militar brasileira. Utilizando arquivos históricos de registros do Congresso, elaboramos um banco de dados abrangente de discursos parlamentares de 1975 a 1986. Especificamente, nossa análise explora uma reforma política exógena que aumentou a competição partidária dentro da oposição durante a fase de redemocratização sob o regime militar. Ao combinar a literatura teórica sobre competição partidária com técnicas recém-desenvolvidas de Processamento de Linguagem Natural (PLN), nossos resultados revelam um aumento significativo no uso de retórica emocional predominantemente negativa pelo principal partido de oposição. Esses resultados destacam o impacto da competição política em atributos de nonpolicy nas estratégias partidárias e demonstram como métodos de PLN podem ser integrados com modelos de competição partidária para estudar o discurso político.
