Abstract

In this paper we estimate the price and income elasticities for five sweet spreads using a two-stage budgeting procedure. The first stage modeled the consumer's budget decision as a Tobit model, where total sweet spread expenditures are based on income and demographic variables. The second stage, including only those households with nonzero first stage expenditures, was treated as a standard consumer allocation problem using the AIDS model. To incorporate population demographics, the AIDS model was expanded by specifying the constant term as a linear function of demographic variables. The coefficients for the prices and expenditures are highly significant and demand is elastic for all five goods. The most significant demographic effects are due to household size, and female food shopper. The theoretical restrictions of homogeneity and symmetry were tested and rejected for the complete system.
