We propose a first order bias correction term for the Gini index to reduce the bias due to grouping. The first order … correction term is obtained from studying the estimator of the Gini index within a measurement error framework. In addition, it … reveals an intuitive formula for the remaining second order bias which is useful in empirical analyses. We analyze the …

We further propose an IV approach, showing that it is not susceptible to this spillover bias in … Norway, we reveal a positive spillover bias in the grandfather coefficient estimates, and the combined evidence from our OLS …

We examine the extent to which self-reported health measures suffer from reporting bias and then characterize how this … reporting bias affects the estimation of income-related health inequality as measured by the concentration index. We run a … comprehensive set of tests of reporting bias using several self-reported health measures and several clinical measures of health …
