Last month, working parents of three- and four-year-old children in England had their weekly entitlement to free childcare doubled from 15 hours to 30 hours, for 38 weeks per year, as the Childcare Act 2016 was implemented. Enabling parents who want to work to do so is smart policy – for the impact it has on household economics, for gender equality and, via those two effects, for the economy as a whole. But devising a policy which is economically as well as ethically right isn’t easy – the gains from parents working, or working more, are easily absorbed by the cost of parents who (entirely reasonably) consume the free childcare without changing their labour force decisions. The Childcare Act is a welcome step in the right direction, but is unlikely to catalyse the change in parental labour force participation necessary to fund the cost. We argue that the economic gain is within reach but that a further expansion of free provision, to 30 hours per week for 47 rather than 38 weeks per year, is necessary to allow free childcare to pay its own way.

Getting free childcare right is important. Parents of pre-primary school aged children represent roughly ten per cent of the potential workforce, so the ease with which they can access the labour market, if they want to, matters at a macro level as well as for household economics. As things stand, we have a ~14 per cent difference in employment rates for mothers of children below the age of six versus above. Closing that gap would have a real impact both for families and for the Treasury. And the effects of parental (typically maternal) labour force detachment are long term. It is estimated that each year out of the workforce costs a mother 3.4 per cent of her expected earnings for the remainder of her working life. That fits with the gender pay gap being so much wider for mothers than for all women.

So there is a real prize from getting childcare right – both economically and as a contribution to gender equality over time. But it is a costly prize to attain. Free childcare suffers “crowding out” effects – parents substituting free formal childcare for privately funded formal, or informal, care – without changing their labour force decisions. Those crowding out effects are capable of swallowing up the economic gain from parents who do start or increase work. Studies in Canada for example have shown that as much as one third of the increase in consumption of childcare when it is made free consists of parents reducing informal care arrangements without changing their labour force behaviour.

But crowding out makes the economic case for free childcare difficult, not impossible. Crowding out just means the policy needs to work harder to earn its keep. Specifically, it must be designed to materially change the labour force participation of parents currently not working who want to, and the intensity of work of those who already are, but want to do more.

Will the increase from 15 to 30 hours per week, for 38 weeks per year, achieve that increase in employment and of hours worked on sufficient scale? We are not optimistic, because the employment options to most parents will remain highly constrained. The Act will enable most parents to consider close to full-time employment (30 hours weekly) during term-time only, or part-time employment throughout the year. Given: i) the significant fixed costs of employment on both the supply and demand side; ii) the limited pool (and, on average, relatively lower pay) of part-time employment opportunities and iii) that for some parents employment is a binary decision, the Act is unlikely in our view to optimise parents’ labour force response.

But that is a reason to advance not retreat, in our view. There is evidence that the parental response to childcare subsidies in terms of labour force behaviour is non-linear, i.e. that “tipping points” exist around which a relatively small further increase in free provision can elicit a disproportionately large supply side response. It seems likely to us that making the option of full-time employment available to parents, by greatly expanding the universe of employment options (and, on average, hourly pay on offer) is such a tipping point. If policy falls short of that inflection point then crowding out effects dominate; if it passes that threshold, the gain is disproportionate to the incremental cost.

Asking government to spend yet more is always easy. But this is a policy which would stand on its own two feet. Our analysis assumes an elasticity of parental labour force participation of -0.4 (relatively conservative versus several academic studies) and that hours worked by already employed parents would increase by ten per cent (versus a ~25 per cent increase in free childcare). Allowing for crowding out effects, we conclude that the cost and benefit to taxpayers from this expansion of policy would both be in the range of ~£400m, i.e. that it would be close to self-financing. We do not allow for a “tipping point” (were we to do so the absolute elasticity value of -0.4 would be much higher). If our hypothesis about tipping points is right, the taxpayer return from this policy expansion would be compelling.

Policies which are economically sensible, ethically commendable and liable to be, in the main, electorally popular are few and far between, but our work suggests that this could be one of them.
