Abstract
Political parties are essential for structuring parliamentary decision-making in democracies. However, in some countries, as many as 10% of legislators experience spells outside of parliamentary party groups. This paper sheds light on this important group of independent politicians by analyzing whether and when they join existing or new party groups. We argue that the electoral motivations of members of parliament (MPs) affect their incentives for reaffiliation. We capture electoral motivations with two factors: the personal vote of legislators and membership in minor parties that do not have their own parliamentary groups. We test this argument using a novel dataset covering over 800 spells of independence and 500 entries into party groups in three Central and Eastern European countries (Lithuania, Poland, and Romania) since the early 2000s. We find that independents affiliated with a minor party are more likely to form a new party group, while MPs with a significant personal vote or those not affiliated with a minor party are more prone to join an existing party group.
