Field reading, Financial inclusion
Every other transition, electric mobility, off-grid solar, water services, agri-inputs, depends on one prior question: can people pay for it, over time, in the way their income actually arrives?
Finance is not a sector to be studied on its own; it is the substrate every other transition rides on, and where the substrate is thin, the transition it was meant to carry stalls.
Mobile money in East Africa has become the canonical bounded-leapfrog: a payment rail that reached tens of millions of previously unbanked users without waiting for the formal banking system to build branches. It carries wages, remittances, PAYG solar payments, motorcycle-taxi earnings, school fees, and increasingly, credit. It also has a ceiling, at interoperability between operators, at merchant acceptance fees, at the credit-scoring architecture that is still catching up.
Understanding what the rail can carry, and where it snaps, is a first-order question for any project that assumes people will "pay a little each week." The Lab's reading of finance-and-payment systems reads the rail from the user's side: what a transaction feels like, what it costs when the fee is small enough not to notice, when it fails, and what people do when it does.
The pattern that shows up in Kenya (M-Pesa), Uganda (multiple providers, interoperability by regulation), and Tanzania (mature multi-operator market) recurs in adapted form across West Africa (Orange Money, MTN MoMo, Wave) and South Asia (bKash, GCash, PhonePe). The specifics differ; the structural question, who does the rail reach, at what cost, for what use, remains the same.
Micro-payments only work if they fit the rhythm of income. A PAYG solar system priced at "a dollar a day" is easy to justify on paper. In practice, income for many users arrives once a week or once a month, in cash, with obligations attached. Whether the payment schedule fits the income rhythm, or is fighting it, decides adoption and default. A rider whose fare income comes in through the day can pay daily; a farmer whose income arrives twice a year at harvest cannot, no matter how small the daily figure looks.
The observable signal from the field is not the sticker price; it is what happens on the third missed payment: whether the product locks, the household defaults, the vendor extends, or the buyer swaps to an informal alternative that fits the rhythm better.
Every transaction costs something. Per-transaction fees, agent commissions, failed transfers, KYC hassles, PIN resets that require an agent visit, "wallet locked" errors after too many attempts. Small frictions accumulate into a real cost of participation. Reading that cost from the user's side, not the platform's, tells you whether the rail is genuinely inclusive or merely present. A wallet that seven percent of transactions fail on is a different product from one that fails half a percent of transactions on, even if headline penetration statistics treat them the same.
Where a market has one dominant operator, the rail is deep but walled; where a market has several without interoperability, the rail is broad but fragmented. Whether the state or the regulator has the capacity to require or enforce interoperability decides whether the rail scales past a single provider. This is the state-capacity hinge for financial inclusion: leapfrog technology can reach very far, but only as far as the coordination the state has not built forbids.
The next wave of financial inclusion is not payments; it is credit built on the payment history. Whether the credit-scoring architecture treats the informal economy fairly, or replicates the exclusions of the banking system it was supposed to route around, is the BRW framework's central question for finance: is the new credit product bypassing the incumbent, or being repurposed by it? Nano-loans marketed as "instant credit for the underserved" have, in several markets, become a debt-trap architecture with default rates that would be unacceptable in a regulated bank; understanding whether the leapfrog is real requires reading who takes the credit, on what terms, and what happens when they cannot repay.
Field research at the transaction level. Interviews with users about specific payments made in the last week, with their own phone in hand, so recall is grounded in the actual receipt rather than in a stated preference. Agent-network mapping in the neighbourhoods the study serves, timing agent availability against the working day. Merchant-side interviews on why cash still dominates certain transactions and what would change that. A short structured survey to size the pattern at scale, in the local language, calibrated to the operator mix of the market.
The BRW framework enters at analysis: is the payment product bypassing the incumbent bank, repurposing an existing informal network (rotating credit schemes, remittance chains), or weakening the incumbent's grip through a visible cost or convenience advantage? Different mechanisms have different failure modes, and the field study is where the mechanism gets identified.
The clearest illustration is the mobility case in Nairobi, where PAYG financing on the electric motorcycle, priced against a rider's daily fare income and enforced through a payment rail the rider already uses, is what actually carries the e-mobility transition across the affordability threshold. Without the rail, the vehicle would not have crossed; with it, adoption follows the arithmetic. The same pattern runs through off-grid solar (SolShare, M-KOPA, Sun King, Fenix, and others built on PAYG rails), agricultural inputs on credit against future harvest, and school-fee financing.
Every one of these products is a claim about the payment rail as much as it is about the product itself. Reading the rail is therefore not a specialist detour; it is the pre-condition for reading any of the transitions the rail carries.
Finance is the transition that decides how far the others go. A payment rail that reaches everyone is a public good; a payment rail that reaches most but excludes the rest is a mechanism of inequality. The Lab reads them from the user side, in the daily-economics rhythm they actually meet, and reports honestly where the rail carries the promise it was sold on and where it breaks.

This is a Lab reading of the payment-and-credit rail question, drawn from the same field method used in the the mobility engagement and applied across the Lab's cross-sector work. To discuss a study, see Contact.
