We modify their model to achieve simple point identification and estimation of the economies of scale of consumption of each good, and we provide a new index of household level economies of scale. Our model has a linear form, permits households of varying composition, including children, and accommodates unobserved heterogeneity in both preferences and in the economies of scale of each good.
