Party Elites’ Preferences in Candidates: Evidence from a Conjoint Experiment

Party elites selecting candidates are crucial for the composition of parliament. Yet, despite their pivotal position within the party, we know only little about their preferences for potential candidates and how their own backgrounds shape these preferences. This paper presents results from a conjoint experiment carried out with party delegates chosen to select the candidates for five German parties in the run-up to three state elections. Theoretical expectations derived from the principle-agent framework on delegates’ preferences in candidates are evaluated. Analyses show that delegates prefer attributes indicative of quality and socio-demographic similarity in candidates. Additionally, I show that these preferences for candidates differ between inexperienced and experienced delegates, the latter showing a stronger preference for valence attributes in candidates. These findings contribute to our understanding of the role of personal attributes of selectors for candidate selection and hold crucial implications for the composition of legislatures and long-term effects on public policy.
