Experimental Design
Informed by a combination of our research and work experiences in the country, feedback from our implementing partners, and an initial quantitative study of the relevant population, we propose two interventions: (i) Information and Training (IT): we hypothesize that knowledge on technology and return on investment act as binding constraints. We assume it is difficult for urban poor to acquire information about the technology and harness potential benefits of Mobile money (MM). Thus, providing information about the potential returns from MM and knowledge about how to use the service should increase MM adoption and use. To relax these constraints, we follow successful studies using training and information treatments in other domains such as technology adoption (e.g., Aker, 2011; Campenhout, 2021) and tax compliance (e.g., Doerrenberg and Schmitz, 2017; Shimeles et al., 2017) and introduce practical training combined with information as our first treatment. The treatment includes information about the benefits of mobile payment and practical training on how to use MM. It involves in-person visual and practical demonstration of how to download the mobile app (for smart phone users), install and use the mobile pay service (both for smart phone and USSD users). We expect the training will remove knowledge and skill binding constraints and increase adoption and use of MM. The study will use ‘telebirr’ and and MM provided by banks. (ii) Information and Financial incentive (IF): we hypothesize limited financial resource, uncertainty about return on investment, and lack of trust constitute additional binding constraints in adoption of MM. To remove this binding constraint, we use financial incentive to try the service. We will deposit the incentive on the MM account of beneficiaries for those who will have account at the time of the payment. Telebirr allows also to transfer money to any person who has mobile number regardless of subscription to Telebirr service. Those who do not subscribe to the Telebirr service can then withdraw the money at the Telebirr agent or at any Ethio-telecom sales office showing identity card and the text notification message that Telebirr sends when money is transferred to them via their mobile number. For the others who will refuse to get the payment in mobile transfer form, we have a couple of options: we will, deposit the money in their bank accounts, pay in mobile airtime, and if these all options do not work for any reason, we will pay them in cash money.
We will pay beneficiaries different amounts that could help to estimate elasticity. We will also vary the financial incentive (for instance, 1.5, 3, & 4.5 USD) to gauge the difference in response because of variation in financial payouts. We expect the financial incentive will improve trust, reduce uncertainty, and hence increase adoption and use of MM. Similar to the first treatment, the second treatment also includes information about potential returns from MM. To shed light on the sustainability of mobile money transactions after the incentive expires, we will collect the endline data months after the incentive period expires.
