Informal institutions and gendered candidate selection in Brazilian parties

Six electoral cycles since the implementation of Brazil's gender quota, just 15% of the 513 members of the Chamber of Deputies are women. We ask how parties' use of informal institutions mediates the effectiveness of the gender quota. Drawing on data from more than 4,000 state-level party organizations, we show that parties employ informal practices that intentionally and non-intentionally interact with gender equity rules to affect women's political representation: the intentional nomination of phantom candidates ("laranjas") allows parties to comply with the letter of the quota law, without effectively supporting women's candidacies-to the detriment of women's election; meanwhile, the extended use of provisional commissions to minimize oversight on candidate selection poses an obstacle to the quota and women's candidacies and election more generally. Quota resistance characterizes an instance of both the likely inadvertent effects of informal institutions employed for non-gendered motivations and party leaders acting to preserve their own power.
