It is argued that female voters are biased toward female candidates shown to represent the interests of women to a greater extent than their male counterparts. To explore the question of whether women are more likely to vote for female candidates, this paper investigates the influence of rising female labor force participation on female candidates’ vote share in elections in Taiwan from 1994 to 2014. The results show that the increasing supply of foreign domestic workers leads to more women entering the labor market, which in turn gives rise to more votes being gained by female candidates.
