This study draws attention to empirical evidence for the United Kingdo
m and Canada rejecting the separability of household commodity demands
from labor supply. As might be anticipated on the basis of these reje
ctions, using Canadian data, we find clear patterns in the average exp
enditure shares for husband-wife families classified by whether both s
pouses, only the man, only the woman, or neither worked. The patterns
remain even when the families are further categorized by child-status
and by family income. A number of implications of these findings are c
onsidered.
