Sample size (or number of clusters) by treatment arms
There are 356 treatment and 97 control. The distribution of treatment-control varies by cluster (village) as randomization was done at individual rather than cluster level.
At the time of the baseline survey, 342/453 households were successfully surveyed, a 75% response rate. Due to Covid-19, the endline survey was implemented as a phone survey, as in-person surveying was not legal in Myanmar at the time. At the time of the endline survey, we resurveyed baseline respondents, and also attempted to survey as many respondents who were missed at baseline (from the 25%), successfully reaching 94, so another 20.7% of the original sample of 453. We implemented a modified survey instrument at endline with this group, which also asked about a subset of variables that would have been asked at baseline. This allowed us to partially reconstruct a baseline-endline panel.
Of the 342 baseline respondents, only 1 attritted in the endline phone survey, so we resurveyed 341 baseline respondents at endline. Added to the 94 who were missed in the original baseline, that gives us 435 total respondents (a 96% overall response rate), 341 who have full baseline-endline panel data, and 94 who have partial baseline-endline panel data.
We can also break down these figures by sample group, which we describe as group 1 (188 randomized treatment), group 2 (168 credit officer selected treatment), and group 3 (97 control).
-Group 1. 186 completed, 2 not completed = 188. Of the 186, 152 responded at baseline and endline, and 34 only at endline.
-Group 2. 162 completed, 6 not completed = 168. Of the 162, 124 responded at baseline and endline, and 38 only at endline.
-Group 3. 87 completed, 10 not completed = 97. Of the 87, 65 responded at baseline and endline, and 22 only at endline.
