This article explains variations in levels of institutionalization across legislatures of the world. It construes institutionalization as an equilibrium outcome that emerges from beliefs and investments made by political actors. Drawing insights from work on US congressional institutionalization and congressional organization, and on comparative party system institutionalization, it provides an index to measure congressional institutionalization. Using this index, it explores the constitutional factors that affect levels of congressional institutionalization. The empirical results raise a warning with respect to building comparative implications from an excessive focus on one particular case.

This article analyzes the use of vetoes in multiparty presidential systems. It suggests that the nature of executive-legislative bargaining is fundamentally altered when multiple parties compose the legislature and when presidential veto prerogatives are extended to incorporate partial (line-item) vetoes. Using a data set that includes all bills passed by the Argentine Congress in the past 25 years, we estimate veto occurrence under different scenarios. Our findings are at odds with received expectations: whether the President holds a majority in Congress or not fails to explain variations in the likelihood of vetoes. Instead, the level of significance of legislation is relevant for predicting vetoes, with landmark legislation being more likely to be vetoed regardless of levels of support for the president in Congress. In addition, partial vetoes become the preferred alternative when confronting legislation initiated by the president herself.

Cataloging-in-Publication AbstractThis paper proposes an agenda for the study of the determinants and the processes by which strong policymaking institutions emerge, with emphasis on the most central democratic institution: the legislature. It reviews extant theories of institutionalization, and proposes further ways of specifying and studying the concept. It emphasizes the notion that investments and beliefs are the driving force of Congress institutionalization and of its relevance in the policymaking process. Making use of several indicators of Congress institutionalization, it provides evidence suggesting that Congress institutionalization has an impact on the qualities of public policies and on economic and social development outcomes. It also explores some "constitutional" factors that may promote Congress institutionalization. Given that a central theoretical argument of this paper is that the institutionalization of legislatures is a process that includes various self-reinforcing dynamics, the paper also undertakes the preliminary steps in developing a comparative case study of the evolution of Congress institutionalization in two Latin American countries: Argentina and Chile.JEL Codes: D70, D72, H0
