Why are some parliamentarians' bills more likely to progress? Sponsorship as a signal

Abstract

This article offers an empirical test of why some legislators' bills are more likely to move forward in the legislative process. We argue that who signs the bill matters when it comes to the level of support that the proposal receives. Successful bills will be sponsored by a greater number of members (bandwagonfactor) and political adversaries (support across the aislefactor). On the contrary, failed initiatives will be those sponsored by inexperienced parliamentarians (newcomersfactor). We examine the case of Chile and test the expectations with legislative data on parliamentarians' bills.
