While randomized controlled trials have become a key tool to evaluate the effectiveness of development programs and policies aimed at reducing poverty, it is difficult by nature to design randomized infrastructure projects to identify the causal impacts. This seminar will examine how natural experiments and other evaluation methods can be used to rigorously evaluate infrastructure programs using a unique panel data set from an irrigation project in Sri Lanka under a natural experimental situation where a significant portion of irrigated land was allocated through a lottery mechanism. Also, we capture a set of new poverty outcomes, such as social capital and trust, using artefactual field experiments. By combining this data, we quantify causal micro-impacts of infrastructure on people's social capital.
