Household Equivalence Scales: Theory versus Policy?
梳理了家庭等价规模的三种定义的历史与哲学渊源，指出理论上的严谨化并未使相关研究更贴近政策制定者的实际需求。
Researchers agree that household equivalence scales are intended to measure the variation in income needed to bring households of different composition to the same welfare level. Researchers do not agree, however, about how the term 'household welfare' is to be defined. This article traces the historical and philosophical development of three distinct definitions. When the conceptual bases of several popular methods for the estimation of equivalence scales are explored, it becomes clear that advances in theoretical rigor have not always worked to bring the literature closer to answering questions of policy concern.
