Party unity in parliamentary democracies: A comparative analysis
Open accessAbstract
The level and causes of party unity are under-researched topics in parliamentary democracies, particularly in comparative perspective. This article presents a non-formal model explaining party unity in legislative voting as the result of individual legislators' decisions reacting to the incentives and constraints created by their respective institutional environments. Hypotheses derived from the model are tested against empirical data on party unity in 11 western parliamentary democracies since 1945. On the system level, central party control over nominations and intra-parliamentary resources as well as the strength of parliamentary committees with regard to policy decisions are shown to affect party unity as expected by the model. On the level of individual parties, governing parties are less unified than opposition parties and larger parties show higher unity than smaller ones. Both results shed doubt on frequent claims in the literature.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
