Demand Based Equivalence Scale Estimates for Australia and the UK

This paper compares alternative approaches for estimating equivalence scales from household expenditure data. Discussion focuses upon the limitations of cross-sectional household survey data, and the implications for model estimation. Taking into consideration the biases that are associated with alternative models, a demand system with Éxed price e_ects is identiÉed as the preferred equivalence scale estimation methodology using pooled cross-sectional survey data.
