Replication of quantitative work in development studies: Experiences and suggestions

There is a growing demand for replications of authoritative works in development studies, which reflects recent trends in other social sciences as well as challenges to important quantitative works in development studies where replications have made contested contributions to understanding. At the same time, there is a strong trend within development towards adoption of medical models of evidence-based policy to find out what policies and interventions work. Replication is a key practice of medical (and natural science) research and was advocated frequently over several decades without success. This article addresses the incentives for replication going beyond a narrow focus on extrinsic rewards, reviews some significant examples, discusses behaviour during replication and draws lessons for replicators and replicatees.
