Complex Party Structures Diminish Representation Across Europe

This study examines how party organizational characteristics influence representation in Europe.

Data & Methods

Drawing on a comparative database and data from Comparative Studies of Electoral Systems, it analyzes the relationship between horizontal/vertical integration and congruence across multiple parties.

Key Findings

Complex organizational structures with strong leadership reduce party representation:

• Leadership-dominated parties are less representative
• Complex structures (horizontal/vertical integration) hinder alignment with voter interests

Why It Matters

These findings challenge assumptions that complex party organizations improve representation. They highlight how organizational complexity may actually undermine democratic accountability, particularly in Europe.
