CENTRALIDAD Y PRODUCTIVIDAD LEGISLATIVA EN LA CÁMARA DE DIPUTADOS ARGENTINA, 1983-2019.

What factors impact on the productivity of legislators? In this paper, we argue that legislative productivity depends not only on party affiliation, seniority, gender, and other contextual considerations (e.g., alignment with the executive), as previous studies have shown, but also on the connections between legislators. Our main argument is that legislators' effectiveness in getting their proposals approved by the chamber depends on their centrality in the cosponsorship network. Unlike previous studies of Latin American legislatures, which usually consider bills as the unit of analysis, we focus on legislators and their individual records. We consider individual productivity as the number of authored bills approved by the chamber in a two-year congress. To test our hypothesis, we use data from the Argentine Chamber of Deputies from 1983 to 2019. [ABSTRACT FROM AUTHOR]
