I consider how asymmetric information between the party selectorate and members of Parliament affects the renomination of incumbent candidates. By applying an adverse selection model, I argue that the selectorate looks to past performance to select candidates it expects will gain influence. However, the impact of performance varies according to the need for and availability of information.
The European Parliament (EP) provides a most-likely case for information asymmetry. Studying three elections in 11 member states, I find that the allocation of influential positions in office improves chances of reselection. The effect increases when the allocation is more selective, and when the prior uncertainty around candidacies is high. The study thus proposes a new approach to the relationship between national parties and transnational groups in the EP. It also suggests venues for research on parliamentary politics and candidate selection in general.
