Examine client-facing information collection and processing transaction tasks in microfinance workflows Can technology deliver cost savings to the MFI through efficiency gains? Create an analytical framework in which the cost for a given transaction τ is described by a cost function C (V l, V k, O, L, F, N) Examine the relative cost accrued for task τ under alternate arrangements, LT (low-tech, baseline channel)and HT (high-tech), for a given MFI (For details on the costing model, please see http://research.microsoft.com/~aratan/Cost_Realism_May08_final.ppt ) http://research.microsoft.com/~aratan/Cost_Realism_May08_final.ppt 1

8. © 2007 Microsoft Corporation Implications: Cost-realistic IT deployments The higher the labour productivity gains from the HT channel, the greater the transaction cost savings. The higher the local wage for the task, the higher the productivity-linked transaction cost savings. The higher the variable capital cost reduction, the greater the transaction cost savings. A larger number of transactions per unit of labour/per device greatly multiplies the power of productivity gains per transaction from the use of the HT channel. The larger the operating costs required to run the HT channel (e.g. connectivity costs), the lower the gains from overall cost reduction. The higher the fixed capital investments called for in the HT channel, the more substantial the requirements for high transactional cost savings and low operating cost differentials to ensure the HT channels financial sustainability. 1 Excel-based costing template available at http://research.microsoft.com/~aratan/costing.htmhttp://research.microsoft.com/~aratan/costing.htm

10. © 2007 Microsoft Corporation Virtual currency: Cash-in/ cash-out Rich customers use ATMs & a bank savings account to store value Most of the rich live in dense urban areas and conduct high- denomination transactions The poor are spread out in rural areas and conduct low- denomination transactions Current solutions: ATMs in low- income urban neighborhoods; use existing retail networks that serve the urban and rural poor: e.g. pre- paid talktime outlets 2 Mobile stored-value outlet

11. © 2007 Microsoft Corporation Cash-less transactions Rich customers use PC- or phone- based internet banking; use cheques The poor do not own or access PCs regularly; often have literacy barriers The mobile phones they own are not data-enabled Current solutions: Use SMS or USSD channels, and/or SIM-based applications for mobile payments 2 M-payments user

Text-free UIs for Low-Literate PC Users, ICTD 2007 Is the development impact of mobile-banking services sizeable; is it widespread or specific to particular kinds of poor households? What happens to microcredit repayment rates when the groups regular social interaction is interrupted (by IT-enabled channels)? – Related CMF study on meeting frequency and repayment rates by Roy and Davies. Will efficiency gains in payments channels translate to lower lending rates for microcredit?
