Welfare Measurement and Measurement Error [PDF]

open access: yesReview of Economic Studies, 2001
There is investigated the differential effect of a measurement error for some inequality and poverty measures. It is studied the relationship between the impact of this error and the form of the underlying structural income distribution. All conclusions are based on a good mathematical background.
