摘要：The debate around the healthfulness of food choices for low-income households is still a relevant point of contention for policymakers as they aim to provide tools to incentivize consumption of healthier foods in different ways. Using fluid milk as a case study, and one year of household- level weekly milk purchases data in the Northeastern U.S., we assess the demand for milk of households with income levels above and below poverty, across fat content and packaging size. We find estimated own-price elasticities differing little across samples of households: even in cases where differences emerge, the estimated values, along with price differences experienced by purchasing households do not seem to justify the different purchasing patterns of the two household groups. Household characteristics however show differences in impacting the demand of milk across households with different income levels.
