Experimental Design (Public)
|
Before
We are implementing the study as a cluster randomized controlled trial to measure the causal impacts of FAST and Digitization of savings groups, controlling for observable and unobservable differences across groups and individuals.
Treatment assignments will be made at the savings group level, cross-randomized to ensure that half of all surveyed groups receive the FAST intervention and half receive the Digitization intervention and that there is no correlation between the likelihood of assignment between the two interventions. As a result, roughly 25 percent of groups receiving both interventions and 25 percent receiving neither.

After
We are implementing the study as a cluster randomized controlled trial to measure the causal impacts of FAST and Digitization of savings groups, controlling for observable and unobservable differences across groups and individuals.
Treatment assignments will be made at the village level, cross-randomized to ensure that half of all surveyed villages receive the FAST intervention and half receive the Digitization intervention and that there is no correlation between the likelihood of assignment between the two interventions. As a result, roughly 25 percent of villages receiving both interventions and 25 percent receiving neither.
