A Note on Adapting Propensity Score Matching and Selection Models to Choice Based Samples

James Heckman and Petra Todd

No 4304, IZA Discussion Papers from Institute of Labor Economics (IZA)

Abstract: The probability of selection into treatment plays an important role in matching and selection models. However, this probability can often not be consistently estimated, because of choice-based sampling designs with unknown sampling weights. This note establishes that the selection and matching procedures can be implemented using propensity scores fit on choice-based samples with misspecified weights, because the odds ratio of the propensity score fit on the choice-based sample is monotonically related to the odds ratio of the true propensity scores.
