Abstract
Over a hundred countries use gender quotas in politics to increase female representation. Yet, when quotas apply only on party candidate lists, parties often strategically respond, resulting in female representation being at the lower end of what is compatible with quotas (Esteve-Volart and Bagues, 2012). This project will exploit an electoral setting in Chile where the party's ability to manipulate the fraction of women elected through candidate choice is limited by law. Using a randomized information campaign, which consists of sending letters to voters from randomly selected voting booths, I will examine whether informing voters about the law to ensure gender parity impacts voter candidate choice and partisan preferences. The aim is to use the findings to evaluate the underlying causes for female under-representation in politics.

Primary Outcomes

Primary Outcomes (end points)
Votes:
- Percentage of votes for women over total votes.
- Percentage of votes for women of the three major coalitions competing.

-Percentage of votes for women according to their ranking in the list
-Percentage of invalid votes
-Percentage of votes by coalition
Turnout:
- Percentage of registered voters that voted.
- Percentage of male and female voters that voted.
- Percentage of people by age that voted.
Primary Outcomes (explanation)

Secondary Outcomes

Secondary Outcomes (end points)
-Spillovers in other elections happening the same day (percentage of votes for women in elections for governor, mayor, and city council; percentage of invalid votes)
Secondary Outcomes (explanation)

Experimental Design

Experimental Design
Treatment is randomized among electoral voting booths in all the urban municipalities in the city of Santiago. There are two treatment arms and one control group:
Control group: No intervention
Treatment 1 (T1): Voters in these voting booths will receive a letter with general information about the election and gender parity in candidates.
Treatment 2 (T2): Voters in these voting booths will receive the same letter as voters in T1, plus information about gender parity in elected candidates.
