Abstract
This paper contributes to the debateon ways to improve the calculation of inequality measures in developing countries experiencing severe budget constraints.Linear regression-based survey-to-survey imputation techniques are most frequently discussed in the literature.These are effective at estimating predictions of poverty indicators but are much less accurate with inequalityindicators. To demonstrate this limited accuracy, the first part of the paper discusses several simulations usingMoroccan Household Budget Surveys and Labor Force Surveys. The paper proposes a method for overcoming these limitationsbased on an algorithm that minimizes the sum of the squared difference between a certain number of direct estimates ofan index and its empirical version obtained from the predicted values. Indeed, when comparing the estimatedresults with those directly estimated from the original sample, the bias is negligible. Furthermore, the inequalityindices for the years for which there are only model estimates, rather than direct information on expenditures,seem to be consistent with Moroccan economic trends.
