A demand systems analysis of food commodities by US households segmented by income Academic Article uri icon


  • Using the 1987-88 Nationwide Food Consumption Survey, twelve food commodity groups were analyzed according to household poverty status. Parameter estimates were used to obtain subsistence expenditures, own-price elasticities, expenditure elasticities, and income elasticities. Own-price elasticities were similar between the income groups for most commodities. However, income elasticities were consistently higher for the lower-income group. The use of average estimates of price and income elasticities for the population as a whole for the projection of individual commodity demands is not likely to be successful if notable changes are evident in income distribution.
