Abstract
I prove that as long as we allow the marginal utility for money (symbol) to
vary between purchases (similarly to the budget) then the quasi-linear and
the ordinal budget-constrained models rationalize the same data. However,
we know that (symbol) is approximately constant. I provide a simple constructive
proof for the necessary and sufficient condition for the constant (symbol) rationalization, which I argue should replace the Generalized Axiom of
Revealed Preference in empirical studies of consumer behavior.
