DP14763 Comparative Politics with Intraparty Candidate Selection

We develop a two-stage model in which parties select candidates before the election. Elections are under first-past-the-post (FPTP) or closed-list proportional representation (PR). Selection is competitive or non-competitive. With non-competitive selection, candidate effort is higher under FPTP. With competitive selection, effort is higher under PR. Under PR, competition motivates candidates to exert effort to be selected (as under FPTP) and to be ranked higher on the list. Empirical studies comparing electoral rules should consider how parties organize, to avoid omitted variable bias. The results also suggest that electoral rules influence how parties organize.
