Electoral effects of candidate valence

• Comprehensive effect of candidate valence on electoral outcomes.
• Conservative test with two-tiered German electoral system.
• Electoral outcomes several percentage points higher for high-valence candidates.
• Even candidates from minor parties benefit from valence.

Ideological proximity is not the sole determinant of electoral choices. Voters frequently select candidates whose policy profiles do not exhibit the closest match with their own policy preferences. Instead, non-spatial factors can govern the vote. The empirical literature has struggled to assess the effect of candidate valence on electoral outcomes due to the challenge of estimating a comprehensive indicator of candidate valence. This paper investigates the effect of non-spatial factors on candidates’ electoral results by estimating candidate valences from a vote advice application. A conservative estimate based on an analysis of the two-tiered German federal election system suggests a surplus of several percentage points for high-valence candidates over low-valence competitors – even for competitors from minor parties.
