Evaluating Microsavings Programs: Green Bank of the Philippines (A)

by Nava Ashraf, Dean Karlan, Wesley Yin and Marc Shotland


Green Bank of the Philippines was known for its product innovation and its ability to bring new products to market. In 2002, Green Bank designed an untested commitment savings product that both gave individuals access to formal savings and helped them commit to reaching their savings goals. Omar Andaya, the Green Bank president, must decide how to evaluate the success of this product. The management team at Green Bank discusses various evaluation methods, including a formal quantitative impact evaluation using a randomized control trial (RCT), and the value an impact assessment brings to the Bank. In particular, they grapple with the question of how success is measured for a product both for the bank and for its clients. The case highlights the issues an organization must consider before deciding to do an impact assessment as well as common design challenges.
