摘要：
This paper clarifies the conditions under which PIGLOG and extended PIGLOG preferences can identify household equivalence scales. The results are of interest to practitioners who have to elect preferences suitable for welfare analysis. It also shows that independent of the base utility equivalence scales are the same whether the budget shares of the demand systems are linear or quadratic in log income. (JEL: D11, D13)
