Expansion and welfare in microfinance: a screening model
Abstract
The expansion of microfinance has triggered concerns of rising indebtedness, and higher default and interest rates. Using a screening model, we show that even if interest and default rates increase due to expansion, borrower welfare may improve. This is because: (i) all borrowers previously denied credit can obtain loans, and (ii) screening costs for pre-existing borrowers go down. Hence, policies that seek to regulate interest and screening levels can be counterproductive.
