This paper considers causal inference and sample selection bias in non-experimental settings in which: (i) few units in … treated units and, hence, in alleviating the bias due to systematic differences between the treated and comparison units …

and show they behave well in realistic scenarios, correcting the large bias problem of the full sample estimator. We use …

censored population. We then correct the derivative for the effects of the selection bias. We propose nonparametric and …

We examine a largely unexplored source of downward bias in peer effect estimation, namely, exclusion bias. We derive … formulas for the magnitude of the bias in tests of random peer assignment, and for the combined reflection and exclusion bias … consistent inference on peer effects without instruments. The method corrects for the presence of reflection and exclusion bias …

In this paper, I present a simple characterization of the sample selection bias problem that is also applicable to the … problem of sample selection bias is fit within the conventional specification error framework of Griliches and Theil. A simple … estimator is discussed that enables analysts to utilize ordinary regression methods to estimate models free of selection bias …

CPS makes no effort to follow movers, these panels exhibit significant attrition, which may lead to bias in longitudinal … construct 'data-based' rather than 'model-based' corrections for bias from selective attrition. The approach is applied to a … statistically insignificant evidence of attrition bias. In contrast, the longitudinal analysis of the marriage premium for males …

We examine evidence on omitted-ability bias in estimates of the economic return to schooling, using proxies for …
