Quality evidence for policymaking: I’ll believe it when I see the replication

This paper by Annette N Brown, Drew B Cameron and Benjamin DK Wood reviews current literature and trends in social science research to emphasise the importance of replication for evidence-based policymaking in international development. The authors discuss four main challenges facing empirical research and offer a new typology of replication approaches - pure replication, measurement and estimation analysis, and theory of change analysis - to address these challenges.
