Semiparametric inference for inequality measures under nonignorable nonresponse using callback data
利用回访数据处理非可忽略无应答下不平等指标的半参数推断
This paper develops semiparametric methods for estimation and inference of widely used inequality measures when survey data are subject to nonignorable nonresponse, a challenging setting in which response probabilities depend on the unobserved outcomes. Such nonresponse mechanisms are common in household surveys and invalidate standard inference procedures due to selection bias and lack of population representativeness. We address this problem by exploiting callback data…
