We develop a method to estimate resource shares - the fraction of total household expenditure allocated to each household member - using OLS estimation of Engel curves. The method reframes the nonlinear model of Dunbar, Lewbel and Pendakur (2013), extended to allow single parent households, scale economies in assignable goods, complementarities between non assignable goods, and supplemented by a linear identification test. We apply the model to data from 12 countries, and investigate resource shares, gender gaps, and poverty. We reject equal sharing, and find large gender gaps in resource shares, and consequently in poverty rates, in some countries.
