Duflo (2001) exploits a 1970s schooling expansion in Indonesia to estimate individual-levelschooling and labor impacts and the returns to schooling. I correct data errors, adjust for potentialsources of bias, follow up later in life, and check sensitivity to two specification choices that...

Duflo (2001) exploits a 1970s schooling expansion in Indonesia to estimate the returns to schooling. Under the study's difference-in-differences (DID) design, two patterns in the data-shallower pay scales for younger workers and negative selection in treatment-can violate the parallel trends...

Replication research can be used to explore original study results that researchers consider questionable, but it should also be a tool for reinforcing the credibility of results that are important to policies and programs. The challenge is to design a replication plan open to both supporting...

This paper provides researchers with an objective list of checks to consider when planning a replication study with the objective of validating findings for informing policy. These replication studies should begin with a pure replication of the published results and then reanalyse the original...
