Quentin: Thanks for highlighting this issue. Two questions: Do we know why faith-based service providers deliver higher-quality service than, say, public providers? In "Working for God?", Reinikka and Svensson (http://onlinelibrary.wiley.com/doi/10.1111/j.1542-4774.2010.tb00551.x/abstract) attributed it to intrinsic motivation. Are there other explanations? Secondly, is it possible to scale up faith-based services from their low market share? If the reason for the better service is intrinsic motivation, it may not be possible to find enough providers with that motivation. To attract more workers, you may have to pay them more, at which point the cost-effectiveness advantage may disappear. Incidentally, these are questions we will be discussing in the February 28-March 1 conference on the 10th anniversary of the 2004 World Development Report, "Making Services Work for Poor People" ( http://go.worldbank.org/IMORKI2LC0 ).
