Abstract

In this research note, I discuss results from a recent study assessing the impact that New Zealand's electoral and legislative system reforms had on levels of vote consensus achieved in the House of Representatives. Using a new legislative vote data set spanning from 1987 to 2007, I find evidence that the institutional changes fostered an increase in consensual legislative vote outcomes. I also provide a brief theoretical explanation of the developments and address a few issues concerning the measure of consensus used and the interpretation of the data.
