Abstract
Despite the recent rapid growth in female labor market participation, poor households in developing countries exhibit a highly asymmetric distribution of household production efforts across genders. Moreover, the poorest of these households cannot afford purchasing labor-saving technologies such as laundry machines. As a result, females have substituted away from leisure, to accomodate their increased labor supply and limited reduction in household labor. We explore whether the limited extent of redistribution of home production efforts between men and women in these households is related to strongly held gender norms regarding home work, and the extent to which these shared beliefs can respond to the availability and experience with labor-saving home production technologies. With this purpose we undertake a pilot intervention where we randomly assign subsidized laundry machines to households in six very poor neighborhoods in Bogota, Colombia, and track changes in gender role perceptions, labor market outcomes, time allocation outcomes, child development and health outcomes, and women's health outcomes for these households and a set of neighboring control households. To account for the potential interferences across treated and control households within these neighborhoods we also randomize the intensity of treatment offer across neighborhoods.

Experimental Details
Interventions
Intervention(s)
Random assignment of treatment offer intensities across six separate neighborhoods (intensity is defined as the number of treatment offers per neighborhood block, and ranges from 1/10 to 6/5).
Subsequent random assignment of laundry machine offers to households in each neighborhood according to its assigned treatment intensity.
Total number of treatment households: 97
Total number of control households: 97
Intervention Start Date
2015-09-20
Intervention End Date
2017-07-31
Primary Outcomes
Primary Outcomes (end points)
1. Female empowerment perceptions.
2. Gender role perceptions.
3. Household time use across genders.
4. Children (less than 5) nutrition and health.
5. Women's health.
Primary Outcomes (explanation)
Female empowerment and gender role perceptions measures will be computed based on the answers to survey questions eliciting female decision-making and gender role-related views of household members.
Time use outcomes will be constructed based on a time-use questionnaire.

Secondary Outcomes (explanation)
Experimental Design
Experimental Design
Random assignment of treatment offer intensities across six separate neighborhoods (intensity is defined as the number of treatment offers per neighborhood block, and ranges from 1/10 to 6/5).
Subsequent random assignment of laundry machine offers to households in each neighborhood according to its assigned treatment intensity.
Total number of treatment households: 97
Total number of control households: 97
Experimental Design Details
Randomization Method
Randomization of treatment intensities across neighborhoods done in office by computer.
Randomization of treatment offer within each neighborhood done through a public lottery.
Randomization Unit
2 levels of randomization:
1. Randomization of treatment intensity across neighborhoods.
2. Randomization of treatment offer within each neighborhood.
Was the treatment clustered?
Yes
