Nairobi, Kenya which includes a Rotating Savings and Credit Associations or ROSCAs initiative. This is a small scale example, however Rutherford (2009) describes a woman he met in Nairobi and studied her ROSCA. Every day 15 women would save 100 shillings so there would be a lump sum of 1,500 shillings and every day 1 of the 15 women would receive that lump sum. This would continue for 15 days and another woman within this group would receive the lump sum. At the end of the 15 days a new cycle would start. This ROSCA initiative is different from the "saving up" example above because there are no interest rates affiliated with the ROSCA, additionally everyone receives back what they put forth. This initiative requires trust and social capital networks in order to work, so often these ROSCAs include people who know each other and have reciprocity. The ROSCA allows for marginalized groups to receive a lump sum at one time in order to pay or save for specific needs they have. Microfinance debates and challenges There are several key debates at the boundaries of microfinance. Loan Pricing Before determining loan prices, one should take into account the following costs: 1) administrative costs by the bank (MFI) and 2) transaction cost by the client/customer. Customers, on the other hand, may have expenses for travelling to the bank branch, acquiring official documents for the loan application, and loss of time when dealing with the MFI ("opportunity costs"). Hence, from a customer's point of view the cost of a loan is not only the interest and fees she/he has to pay, but also all other transaction costs that she/he has to cover. One of the principal challenges of microfinance is providing small loans at an affordable cost. The global average interest and fee rate is estimated at 37%, with rates reaching as high as 70% in some markets. The reason for the high interest rates is not primarily cost of capital. Indeed, the local microfinance organizations that receive zero-interest loan capital from the online microlending platform Kiva charge average interest and fee rates of 35.21%. Rather, the main reason for the high cost of microfinance loans is the high transaction cost of traditional microfinance operations relative to loan size. Microfinance practitioners have long argued that such high interest rates are simply unavoidable, because the cost of making each loan cannot be reduced
