| Summary: | Research on food consumption and expenditures usually employs the use of unitary
models that do not account for type of family financial structure. This research presents
two collective models of household behavior, conditional and unconditional models,
which were used in the analysis of the household data that came from the “Parental
Time, Role Strain and Children’s Fat Intake and Obesity Related Outcomes”. This
research utilized the Generalized Method of Moments in the estimation of the system of
expenditures on food at and away from home to test the validity of the unitary model
by testing one of the implications of this model, the income pooling hypothesis, as well
as family financial structure. It was found that the omission of family financial
structure and not the income pooling hypothesis would lead to the incorrect assertion
that the unitary model is the correct model for the analysis of intrahousehold allocation.
The collective models proposed in this research were found to be preferred to those of
the unitary models. These two models, conditional and unconditional, not only allow
for the effect of earned and unearned incomes of fathers and mothers to be different,
but also incorporate family financial structure into the analysis of expenditures on food at and away from home. This research shows that the parameters of the unitary models
are reduced form parameters that do not represent the effect that the variable of interest
has on the household expenditures category of interest. This research finds that these
reduced form parameters show the total effect which is composed of three parts. First,
the change in the expenditure category of interest that comes about from a change in
the variable of interest when we hold family financial structure constant. Second, the
change in the expenditure category of interest that comes about from a change in the
family financial structure. Third, the change in family financial structure that comes
about from a change in the variable of interest. |
