TWO APPROACHES TO QUANTIFY THE CONCEPT OF EQUITABLE INCOME DISTRIBUTION
提出三种公平定义，偏好福利平等，并讨论揭示法和直接法两种测量方法，应用于荷兰发现公平分配比实际分配更平等，但需进一步研究。
Three alternative definitions of equity are presented, which coincide under special conditions only. The author prefers the definition that equity means equality of welfare. This presupposes measurability of welfare (or utility). Two methods of measurement are discussed, called revealed or indirect and direct measurement. Concrete applications of both are shown, together with their shortcomings. In both cases equitable distribution is found to be less unequal than actual distribution in the Netherlands. Further research needed, on additional relevant determinants of utility and on learnability of some capabilities are formulated.
