Why pay child benefits to middle class families? Writing in the latest issue of the Economic
Journal, Professors Zhiqi Chen and Frances Woolley of Canada's Carleton University suggest an
important justification: that it gives 'at-home parents' an independent source of income. This can
make a genuine difference to family expenditure patterns, allowing more money to be spent on
what the at-home parent thinks is important. And very often, that is things for children.
The authors address a number of key questions about decision-making within families: Does it
matter who receives child benefits? Is there any justification for paying child benefits to middle
class families? Do dual income families spend their income differently from families dependent
on a single earner? And when would we expect spouses to share their incomes or one partner to
transfer part of his income to the other to spend? Chen and Woolley pinpoint a number of factors
that are crucial in determining the outcome of household bargaining:
l each spouse's income, including any government transfers;
l the amount each spouse cares for the other;
l and each spouse's bargaining power - his or her ability to shape household spending
patterns.
When would a £100 tax cut directed at the household's highest earner, usually the father, be spent
differently from a £100 child benefit cheque going to mothers? Chen and Woolley predict that
targeting of benefits makes most difference when the lower earning spouse is partially
independent. That is, when she earns enough not to be reliant on transfers from her partner for her
own personal expenditures, but not so much that she is a substantial contributor to household
goods, like paying the mortgage or buying the family's groceries. Why is this?
A spouse with no income of her own relies on financial support from her partner. If he gets a £100
tax cut, he can give it to her or use it for something else. If she gets a £100 child benefit cheque,
he can let her keep it or - if he has other priorities for spending his money - he can reduce the
financial support he was giving her before. In either case, it makes no difference who receives the
£100.
If both spouses are contributing to a household good, like paying the mortgage, it again makes no
difference who receives the £100. If it goes to the higher earner in a tax cut, he can afford to pay
more towards the family groceries, and the lower earner will have to contribute a little less. If it
goes to the lower earner in child benefit, she can afford to pay more for the groceries, and the
higher earner will have a bit more pocket money.
But when one spouse is partially independent - she earns enough not to be totally reliant on
financial support, but not enough to contribute substantially to household goods - it does make a
difference who receives the benefits. A child benefit cheque makes a real difference to the
recipient spouse's ability to spend money on the things she believes are important - whether they
are her own immediate needs or children's music lessons.
And this is part of the justification for paying child benefits to middle class families. Chen and
Woolley show that families cannot be thought of as a single unit: they are made up of individuals.
Sometimes they pool all of their resources, and sometimes they do not. Sometimes families don't
share. When that happens, there is a risk - particularly if one person has little income of his or her
own, little bargaining power and there is little caring between spouses - of 'dependants' falling into
what Rowntree called 'secondary poverty' - living in poverty within a non-poor household.
Paying child benefits to middle class families gives at-home parents an independent source of
income, which can make a genuine difference to family expenditure patterns, allowing more
money to be spent on what the at-home parent thinks is important. And, very often, that is things
for children.
Do dual income families spend their income differently from families with a single earner? The
authors' analysis model predicts that, yes, they do, even after taking account of differences in
things like spending on restaurant meals, those substitutes for home-produced goods. Think about
the earner in a single income family. He wants to spend income in a way that benefits his family.
He has two choices. He can give his family cash, to spend as they wish. Or he can spend money
on something like a better home, which benefits his family but also improves his standard of
living. Which would he be expected to do?
Chen and Woolley's analysis predicts - as common sense in this example suggests - that single
earner families will spend relatively more of their income on household goods, things like homes
and furniture. In a dual income family, both spouses will have money for personal expenditures,
and more money will be spent on goods for personal enjoyment, whether it be CDs or designer
children's wear.
