Abstract
- We develop a method to correct for non-random measurement error in a binary indicator of illicit drugs. Our results suggest that estimates of the effect of self-reported prenatal drug use on birth weight are biased upwards by measurement error - finding contrary to predictions of a model of random measurement error. More accurate estimates of the true effect of drug use on birth weight can be obtained by using the predicted probability of falsely reporting drug use. Thus out-of-sample information on drug use may improve estimates of the effect of reported drug use in other settings.<br />I. INTRODUCTION The adverse consequences of maternal drug use on birth outcomes is a serious public health issue. Clinical data have clearly established that use of illicit drugs during pregnancy [...]
