Primary Outcomes (end points)
We successfully piloted our experiment (key protocols, instruments, proposed design, recruitment and enrollment processes) in a pilot exercise.
Measurements (vendors): For market vendors, we plan to focus on the impacts of four non-price dimensions of the digital competitive pressure from G-Money’s entry, evaluating:
(i) Quality: incidence of transactional fraud or overcharging consumers at vendor retail points,
(ii) Information: tariff posting or display behavior at vendor points or digital market transparency; and whether vendor attempts to discuss transaction tariffs,
(iii) Services: likelihood of vendors’ declining transactions due to liquidity shortfalls or inability to manage liquidity properly; and length of carrying out transactions or consumer convenience,
(iv) Innovation: bundling M-Money with other non-M-Money services or expansions to other lines of business including total exits; changing vendor locations; hours of operations [self- reported]; vendor accessibility to previously unbanked households. We will evaluate the impacts and various dimensions (i-iv) that businesses compete on. We will adapt Annan (2020, 2021) audit study protocols (and surveys) to measure vendor outcomes objectively (and subjectively respectively).
Measurements (potential customers): For consumers, we plan to examine the impacts on trust outcomes. We will field questions that will provide subjective measures of trust in (i) M-Money providers (MTN vs Vodafone vs AirtelTigo vs G-Money), (ii) market vendors, (iii) carrying out vendor-involved transactions on M-Money (opening accounts; cash-in, cash-out), (iv) consumers’ family and friends, (v) commercial and rural banks (e.g., ADB, GCB, etc.), and (vi) the regulator of financial services in Ghana (Bank of Ghana) if they have heard enough about them to say. This allows us to benchmark consumer trust across M-Money and the other financial alternatives. We will supplement this with objective measures of trust measured from trust games between consumers and their local vendors. In its simple form: this entails a real monetary payoff game between the consumers (i.e., trustors) and one randomly selected (anonymous) local vendor (i.e., trustee). We impose vendor anonymity to mitigate against issues of social and individual preferences. Consumers will be endowed with 50GHS and will decide how much to send to another person (i.e., M-Money vendor). We will triple it, so that the vendor receives three times the amount of money the consumer sent. The vendor will then decide how much he/she wants to send back to the consumer. The total payoffs depend on the choices made between the consumers and vendor. Our objective measure of consumer trust will reflect the amount they sent and expected the vendor to send back to them.
We will combine baseline and endline market census, surveys, and audit studies to track the vendor, customer and business outcomes, supplemented with administrative data from GCB Ltd to examine market-wide impacts, including persistence and entry of new vendors.
