As in other regions, in Latin America, quota laws have been established as affirmative action-type mechanisms that are meant to create a balance in view of the inequalities women face in ascending to political office. My study focuses on whether or not quota laws have increased women's presence in Latin American political legislatures and if they have met the intended objectives by the women's social movements that advocated for them. My results indicate that quota laws have not worked in every Latin American country to dramatically increase women's presence in politics. The literature also suggests that quota laws have not entirely been able to produce the desired outcomes as proposed by women's social movements in the region. My research indicates that the effectiveness of quota laws depends on how they are drafted and implemented, that is if institutions have effectively been altered and if the government is taking specific measures to ensure that the law is being enforced. I conclude that if quota laws are not customized to a country's electoral system and applied meticulously by political parties, they will hardly produce any results for women.
