Worldwide, politicians devote increasing attention to the sociodemographic representativeness of political institutions. The underrepresentation of specific groups (and of women in particular) in political institutions is a democratic problem (Phillips 1995). To counter the lack of representativeness of political institutions, measures have been adopted to increase the influx of female politicians in parliaments and governments. Among others, quota regulations have been implemented in several countries in recent years (Dahlerup 2007; Krook 2007).
