Legislative Effectiveness Scores for Brazil's Lower Chamber

Novel legislative effectiveness scores (LESs) measure bill advancement success for sponsors and rapporteurs in Brazil's lower chamber. The data supports analysis of how affiliation with legislative member organizations (LMOs) and political parties influences legislative effectiveness in a fragmented presidential system. It was created by Beatriz Rey for a study on informal institutions in Latin America.

Use Cases

• Analyze the correlation between legislative member organization (LMO) affiliation and legislative effectiveness scores (LESs) for bill sponsors.
• Compare rapporteurship effectiveness scores across different LMO types, such as public security and agribusiness organizations.
• Model the impact of party affiliation on legislative effectiveness, controlling for LMO structure and type.
• Investigate the scope conditions under which LMOs influence effectiveness in multiparty presidential democracies using the provided scores.

Strengths

• Provides novel legislative effectiveness scores (LESs), a specific metric for evaluating lawmakers.
• Focuses on Brazil's lower chamber, a key legislative body in a major Latin American democracy.
• Data is associated with a published academic study, indicating a defined research methodology.

Limitations

• The dataset scope is limited to Brazil's lower chamber, limiting generalizability to other legislatures.
• Sample size and temporal coverage are unspecified, making it difficult to assess statistical power.
• Relies on constructed effectiveness scores which may involve methodological assumptions.
