In practice, empirical work on multidimensional indicators of well-being jux- taposes several indicators of well-being either by studying the uni-dimensional (also called the marginal) distributions of each independently or, alternatively, by aggregating somewhat arbitrarily the set of well-being indicators into a single one. In order to compare well-being using both income and health indicators, this pa- per proceeds instead by using two sets of relatively weak measurement conditions that are sequentially applied to the measurement system. The first set of condi- tions is that (i) both income and health are assumed to generate well-being (better health can make up for lesser income, and conversely), and that (ii) the.
