Real-Wage and Welfare-Ratio Analysis

Real-wage and welfare-ratio analysis measures the material living standards of working people by asking a deceptively simple question: how many baskets of basic goods could a worker's earnings buy? Robert Allen, refining the older Phelps Brown-Hopkins price-and-wage tradition, devised the welfare ratio—annual household earnings divided by the annual cost of a fixed consumption basket scaled to subsist a family. By specifying a spartan bare-bones basket meeting minimum calorie and nutrient needs, and a more generous respectability basket, and by converting wages and prices into grams of silver, Allen made living standards comparable across the great cities of Europe and Asia and across many centuries. The method underpinned his Great Divergence findings, showing that London and Amsterdam workers enjoyed welfare ratios far above bare subsistence while many Asian and southern European labourers hovered near it. It has become the workhorse for cross-cultural comparison of pre-industrial living standards.
