Prior work
This trial is based on or builds upon one or more prior RCTs.
This study is a long-term follow-up (15 years after program start, when program participants will be aged 30-32) of a large-scale clustered RCT that tested three strategies to reduce child marriage and increase girls' human capital in rural Bangladesh: (i) a six-month adolescent empowerment program (Kishoree Kontha), (ii) a conditional in-kind incentive to delay marriage, or (iii) empowerment + conditional incentive. The aim of this follow-up is to estimate program impacts on program participants and intergenerational impacts on their children.

Experimental Design

Experimental Design
Save the Children USA in Bangladesh implemented a broad range of interventions aimed at empowering adolescent girls. The program, Kishoree Kontha (Bangla for “adolescent girls’ voices”), was carried out in five sub-districts in the south central region of Bangladesh over 2 years and concluded in August 2010. A conditional noncash transfer was added to the Save the Children program. The interventions, at the village level, included the random assignment of the following packages:
a. Basic Package: community mobilization, social competency, self-help study support for in-school girls and literacy sessions for illiterate girls.
b. Livelihoods Package: Basic package plus financial competency training.
c. Conditional Stipend/Oil Incentive Package: non-cash incentive in the form of cooking oil conditional on the girl being unmarried. The value of the transfer was designed to offset the financial cost to families in increased dowry from delaying their daughter's marriage.
d. Full Package: Livelihoods Package plus Conditional Stipend.
e. Savings Cross-Cut: villages were randomly chosen from the Livelihoods and Full packages to receive support in establishing girls’ savings clubs.
f. Control Group: 153 villages in total were assigned as comparison.
The packages are structured to reflect different approaches to adolescent girl empowerment in order to separate out the role of different constraints on economic empowerment of women.

Randomization Method
Randomization was done at the natural village level. Out of a sample of 460 target villages, 307 villages have been randomly selected to receive one of intervention packages above. The remaining villages serve as the comparison group.
Randomization Unit
Village-level, stratified by union (a geographical group of villages) and size of village.
Was the treatment clustered?
