Professor Dehejia will present his research at 4pm Tuesday April 12th in E530 Dealy. He will present his coauthored NBER paper “From Local to Global: External Validity in a Fertility Natural esperiement. He and coauthors Cristian Pop-Eleches, and Cyrus Samii investigate whether well-identified treatment effects from “reference” sites can be extrapolated to “target” sites of interest. They use use data from 166 country-year censuses to implement the Angrist and Evans (1998) natural experiment: that is, what is the effect two same sex children on future fertility and labor force participation by mothers. Reference-to-target group similarities in education, calendar year, and mothers’ labor force participation matter, whereas geographical differences per se do not. Errors do not approach zero if the available evidence is naively extrapolated, but with sufficient data extrapolation error goes to zero using a model-based approach.
