Before
Owners and drivers will be invited to use the digital payments technology that aims at reducing transaction costs. In collaboration with the partner company, I designed a base product with three options for randomly varying the amount of information available to the owners on their drivers:
A) No Visibility: The owners can only receive payments from drivers at no fee.
B) Limited Visibility / Limited Liability: The owners get notified each day via text every night of their drivers’ total collection up to the estimated daily usage of digital payments for taxis. If the total balance is above average, the owners do not get notified of the surplus.
C) Full Visibility: The owners get notified and can observe all the drivers’ transactions. They also receive an SMS about the total transactions of the day. This option is currently the only one offered to other types of businesses accepting digital payments.
D) Control group: Waitlisted for the time of the experiment and followed using both survey and administrative data.
The partner company plans to reach further taxi owners/drivers outside of this sample by the end of the pilot study.

We plan to "treat" the control group with either full visibility or no-visibility at endline, with the intent to conduct another round of follow-up in the future. The visibility group will be randomly sub-divided into two groups: whether we nudge the drivers or the owners about the possible contractual changes induced by the visibility to strengthen the treatment effect and measure the trigger of the contractual change if any.
