Do vaccinated children have higher income as adults? I replicate a paper on the 1963 measles vaccine, and find that it is unable to answer the question.
New replication: I find that the results in Moretti (AER 2021) are caused by coding errors. The paper studies agglomeration effects for innovation (do bigger cities cause technological progress?), but the results supporting a causal interpretation don’t hold up.
Should you “trust literatures, not papers”?
I replicated the literature on meritocratic promotion in China, and found that the evidence is not robust.
