Inequality of expenses : the Tunisian case

الملخص EN

This paper examines the evolution of welfare inequality and its origins in Tunisia.

The study is based on consumption expenses using household budget and consumption surveys (1975-1980-1985-1990).

The relationship consumption / welfare will be treated with brief descriptions of the inequality indicator.

The empirical study shows a decrease in global inequality.

The decomposition of the Gini index shows that this movement may be explained by the decrease in the inequality of the food expenditures.

Moreover, this decomposition has allowed for the analysis of the specific contribution of each type of expenses in the overall inequality.
