Abstract
This project aims to estimate consumers’ willingness to pay for mobile money in Tanzania. We randomize households across 29 regions in Tanzania into a treatment group, where they are eligible to receive either a 50% or 100% discount on some mobile money transactions for 8 weeks, or a control group, where they do not receive any discounts. The treatment group is further divided into 4 sub-treatments where discounts are eligible for either (1) all Cash-Out (CO) transactions, (2) all Person-Person (P2P) transactions, (3) all Person-Merchant (P2M) transactions, or (4) all CO, P2P and P2M transactions. We will visit households 3-4 weeks after the discounts end, to measure transaction use outcomes both during and after the discounts are active.

Experimental Design

Experimental Design
Treatment assignment is at the household level, and all eligible individuals in the household will receive the same treatment. We have 9 treatment arms:
1. No discounts offered (control group)
2. Cash-out fees discounted by 50%
3. Cash-out fees discounted by 100% (free)
4. P2P transfers (on- and off-net) fees discounted by 50%
5. P2P transfers (on- and off-net) fees discounted by 100% (free)
6. P2M payment fees discounted by 50%
7. P2M payment fees discounted by 100% (free)
8. Cash-out, P2P, and P2M fees discounted by 50%
9. Cash-out, P2P, and P2M fees discounted by 100% (free)

Treatment assignment is stratified at the enumeration area level. We sampled 113 enumeration areas across 29 regions in Tanzania, and sampled 15 households per enumeration area.
