Abstract
This study examines how customizing motivational messages for volunteer agents by personality traits influences performance and motivation in the context of agricultural extension in Rwanda. We administered a phone survey with 10,187 village agricultural volunteers (FPs) to gather personality traits using Susceptibility to Persuasion Scale (STPS) questions and designed four sets of SMS task reminders that appeal to four different STPS personality traits. We then randomly assigned volunteers to receive (i) no SMS messages, (ii) randomly assigned SMS messages, (iii) personality-matched messages, or (iv) personality-mismatched messages. In addition we cross-randomize whether FPs receive a reminder of the performance goals they set. We will compare self-reported performance and motivation among agents across experimental groups using a combination of phone survey data and administrative data.

Experiment Characteristics

Sample size: planned number of clusters
N/A
Sample size: planned number of observations
10,187 farmer promoters.
Sample size (or number of clusters) by treatment arms
Control with goal reminder group (C.a): 1,274
Control without goal reminder group (C.b): 1,273
Random message with goal reminder group (T1.a): 1,273
Random message without goal reminder group (T1.b): 1,274
Matching message with goal reminder group (T2.a): 1,273
Matching message without goal reminder group (T2.b): 1,273
Mismatching message with goal reminder group (T3.a): 1,274
Mismatching message without goal reminder group (T3.b): 1,273
Minimum detectable effect size for main outcomes (accounting for sample design and clustering)
If we are able to collect outcomes from all farmer promoters (10,187), we will be able to detect a 4.3% increase in number of farmers FPs helped register for subsidized inputs, 2.8% increase in number of training meetings FPs held on their demonstration plots, and 3.7% increase in number of farmers FPs trained on their demonstration plots, with 80% power at 5% significance.
