Size,Power, and Electoral Systems: Exogenous Determinants of Legislative Procedural Choice

I tested hypotheses about the relationship between exogenous institutions and legislative procedural choice using a unique cross‐sectional approach and a dataset gleaned from 55 legislative bodies from around the world. I focused on three entrenched characteristics of legislative bodies that we have theoretical reason to think will shape procedures: size, the relative power of the chamber, and the method by which its members are selected. Relatively small and powerful bodies generally have decentralized procedures. To a lesser extent, we can say the same of chambers that have electoral systems that incentivize the personal vote.
