For estimation purposes, one classification was eliminated from each group of
variables to prevent perfect collinearity. The base group of individuals and omitted
variables are given in Table 1. Based on previous literature, females (Nayga; Bender
and Derby, 1992; Guthrie et al.) and households with children (Feick, Harrmann, and
Warland, 1986; Guthrie et al.) were initially hypothesized to be most likely to be label
users. Older individuals were expected to be less likely to be nutritional label users
(Bender and Derby).
