“…France, for example, employs a two-round single-member district (SMD) system to elect MPs to the lower house and PR in EP elections, which results in a higher proportion of women in the EP. This hypothesis is congruent with a large body of literature offering evidence that PR tends to produce more equitable outcomes in terms of gender representation than SMD plurality rules in national parliaments (Beckwith, 1992; Castles, 1981; Caul, 1997, 1999; Darcy et al., 1994; Duverger, 1955; Jones, 2009; Kenworthy and Malami, 1999; Krook, 2010; Lakeman, 1994; Lijphart, 1984, 1999; Matland, 1993; McAllister and Studlar, 2002; Norris, 1985, 2004; Norris and Krook, 2011; Paxton, 1997; Paxton and Hughes, 2007; Paxton and Kunovich, 2003; Reynolds, 1999; Reynolds and Reilly, 1997; Rule, 1987, 1994; Salmond, 2006; Tripp and Kang, 2008; Vengroff et al., 2000; Wangnerud, 2009). Since 1999, elections to the EP employ variations of PR formulas, while national elections are run on a variety of electoral rules and district magnitudes.…”
