Abstract:
The Bayes estimators of the Gini index, the mean income and the proportion of the population living below a prescribed income
level are obtained in this paper on the basis of censored income data from a pareto income distribution. The said estimators
are obtained under the assumptions of a two-parameter exponential prior distribution and the usual squared error loss function.
This work is also extended to the case when the income data are grouped and the exact incomes for the individuals in the population
are not available. The method for the assessment of the hyperparameters is also outlined. Finally, the results are generalized
for the doubly truncated gamma prior distribution.
