-generation process, the least-squares estimators have smaller bias (in fact zero bias) but larger variances in the long regression than … in the short regression. But if the long regression is also misspecified, the bias may not be smaller. We provide bias …

the method does not reveal substantial reporting bias in measures of health disparities. …Heterogeneity in reporting of health by socio-economic and demographic characteristics potentially biases the … measurement of health disparities. We use anchoring vignettes to identify socio-demographic differences in the reporting of health …

We propose a first order bias correction term for the Gini index to reduce the bias due to grouping. The first order … reveals an intuitive formula for the remaining second order bias which is useful in empirical analyses. We analyze the … it reduces a considerable share of the bias due to grouping. …
