Abstract
In this project, we study the impact of the introduction of a new financial product, mobile banking (savings), on attitudes towards sharing money with others. Our study is motivated by previous findings that formal financial products allow people to "hide" savings from social pressure (Carranza et al., 2022 and Riley, 2022 among others) as well as the literature showing that exposure to financial products and financial markets can affect attitudes towards sharing money with a spouse (Riley, 2022), political views (Kaustia et al. 2016, Jha, 2015), attitudes towards risk (Lu et al. 2022), attitudes towards meritocracy and personal responsibility (Margalit and Shayo, 2021) as well as attitudes towards peace and interethnic conflict (Jha and Shayo, 2019). Our project sits at the interaction of these two literatures. Our goal is to study whether being introduced to mobile banking affects attitudes towards sharing and whether this is driven by a wealth/savings effect.

To do this, we conduct an RCT in which people are given cash grants either in the form of cash, a transfer to a mobile bank account or a transfer to a mobile bank account with an incentive to save. We track people's attitudes towards sharing with others using repeated surveys over a 6-8 month horizon in which we measure attitudes (along with a range of other outcomes - we are using the same infrastructure as in another RCT).

Experimental Details

Interventions

Intervention(s)
We will give money grants to all subjects, with some people receiving the grant in cash and others in the form of a transfer to a mobile bank account. The mobile banking arm will further be randomized into an "incentivized usage" arm in which participants are offered cash incentives to provide evidence of saving in the bank account.

Experiment Characteristics

Sample size: planned number of clusters
There will be 3 clusters. First cluster will be distributed cash. Second cluster will be given mobile money. Third cluster will be given mobile money with savings incentive.
Sample size: planned number of observations
Total number of participants in two campuses (Kigali and Kiziba campuses of Kepler in Rwanda) is estimated to be around 600.
Sample size (or number of clusters) by treatment arms
Participants will be evenly distributed among 3 clusters.
Minimum detectable effect size for main outcomes (accounting for sample design and clustering)
