Abstract: Following recommendations from the Stiglitz et al. (2009) Commission, this paper proposes the use of a new methodology to measure the joint distribution of households’ income, consumption and wealth. Based on a multi-dimensional extension of the generalized mean framework, the paper justifies the application of this methodology based on a set of standard and acknowledged properties. The derived multi-dimensional index has an intuitive structure, which allows evaluating the overall material conditions of households under different perspectives and with varying sensitivity to distributional issues. Under its general form, the index encompasses a class of sub-indices that impose various restrictions on its parameters; the paper discusses the extent to which different restrictions on parameters affect the multi-dimensional assessments of various population groups, and provides some empirical illustrations using those different specifications. The question addressed by the multi-dimensional measure presented here is whether the joint consideration of household income, consumption and wealth modifies substantially the picture of material living standards of different individuals and groups relative to the one provided by income alone. Based on the dataset used here, the paper provides strong evidence on the importance of such a multi-dimensional assessment.
