Varieties of Intra-Party Democracy

Abstract

This chapter introduces a new, two-dimensional way of measuring intra-party democracy (IPD). It is argued that assembly-based IPD and plebiscitary IPD are two theoretically different modes of intra-party decision-making. Assembly-based IPD means that discussion and decision over a certain topic takes place at the same time. Plebiscitary IPD disconnects the act of voting from the discussion over the alternatives that are put to a vote. In addition, some parties have opened up plebiscitary decision-making to non-members which is captured by the concept of open plebiscitary IPD. Based on the Political Party Database Project (PPDB) dataset, indices are developed for the three variants of IPD. The empirical analyses here show that assembly-based and plebiscitary IPD are combined by political parties in different ways while open party plebiscites are currently a rare exception.
