Abstract
Savings have been shown to reduce vulnerability and allow investments in human and physical capital that are needed to escape poverty. Yet saving rates in developing countries are very low. This begs the question of how to increase savings among low-income individuals. In this experiment in all regions of Uganda, we test two interventions against a "bare account" benchmark: first, savings "coaching" by phone and SMS, and second, the promise of a savings-driven loan conditional on regular savings. Outcomes include savings activity and savings balances, and progress towards clients' personal saving goals.

Experimental Design

Experimental Design
New clients are randomized to either savings coaching (phone calls and SMS), a savings-driven loan that is offered conditional on demonstrating regular savings. Randomization is stratified on gender, age, and income level.
Experimental Design Details
Not available
Randomization Method
Randomization is done by a computer, in the ODK software.
Randomization Unit
Household (1 individual per household)
Was the treatment clustered?
No

Experiment Characteristics

Sample size: planned number of clusters
1,600 individuals.
Sample size: planned number of observations
1,600
Sample size (or number of clusters) by treatment arms
533 control, 533 coaching, 533 savings-driven loan
Minimum detectable effect size for main outcomes (accounting for sample design and clustering)
The minimum detectible effect size for comparing a treatment (either coaching or savings-driven loan) against the control group, with 80% power, and a statistical significance level of 0.05, is 0.17 standard deviations.
