Impact Evaluation Methods with Applications in Low- and Middle-Income Countries

Economic development is a process of trial and error, innovation and experimentation, success and failure. Given the right institutions, some not unfavorable resource endowments, and a bit of luck, incomes can grow, health can improve, and human development can flourish; other times, things don’t turn out so well.

Given the urgency of development challenges, it is imperative that we learn quickly from our mistakes and build robustly on our successes. The hope is that by understanding what kinds of innovations and policies “work” to improve the lives of the deprived and vulnerable, and how they work, we might be better placed to accelerate the process of development more generally. But how can policy makers and international development practitioners be sure they’re “making a difference?”
