Are migrants good for the UK economy?

Analysing two apparently contradictory studies that have been published about the impact of migration on the UK economy.

Two studies about the impact of migration on the UK economy have been published which – if media reports are to believed – appear to contradict one another. A closer reading of these reports, however, shows that in fact they come to very similar economic conclusions. Even so, from reading them it is possible to suggest very different approaches to migration policy.

One study by Professor Robert Rowthorn led to headlines such as: “Further proof of damage created by immigration” and: “How mass migration hurts us all”.

The second study is a paper published by Lineskova and others in the latest issue of the National Institute Economic Review which led to headlines such as: “Reducing immigration would slow UK economy and lead to tax rises” and: “Cameron’s migration cap would leave Brits poorer and taxes higher

So clearly the two reports have created space for some news outlets to pick their own truth. But what should we make of these different studies – and what do they contribute to our understanding of the impacts of migration on the economy?

Long-term impact on GDP

Both studies look at different annual net migration scenarios in the future to provide a picture of the long-term impact of migration on GDP and GDP per capita. The future level of net migration (that is, the difference between immigration and emigration) determines the size and age structure of the UK population.

As shown in Figure 1, if all other things remain equal, a higher level of net migration is expected to lead to a larger UK population (see complete explanation here).

But migrants also tend to be younger than the overall UK population and net migration is also likely to decrease the “dependency ratio” – an assessment of the number of people of working age compared to the number of people of retirement age. For instance, Rowthorn suggests that the dependency ratio will be 3.5 percentage points lower with annual net migration of 225,000 compared to an annual net migration of just 50,000 (Rowthorn defines the dependency ratio as the number of people 65 years of age and above per 100 persons aged 15-64). Figure 2 presents the 15-64 years old population of the UK under different assumptions about net migration.

Rowthorn suggests that, given a set of assumptions about employment rates and labour productivity: “GDP per capita is 3% higher in 2087 with high migration than with very low migration”.

The paper by Lineskova and others looks at two scenarios: net migration of 200,000 and a lower migration scenario, which assumes that net migration is reduced by around 50% – close to David Cameron’s migration target of less than 100,000. They find that by 2060 GDP per capita would be 2.7% lower under the lower migration scenario.

Given the impact of net migration on the size and age structure of the UK population it comes as no surprise that both studies conclude that higher net migration will be associated with a higher level of GDP and GDP per capita.

Long-term fiscal impacts

The two studies also look at the long-term potential “fiscal implication” – the impact on UK government finances – of migration to the UK. Rowthorn also looks at the short-term fiscal impact of migration. Rowthorn scrutinises previous analysis from the Office for Budget Responsibility which suggests that lower levels of net migration will lead to higher public sector net debt to GDP (see Figure 3). While Rowthorn does not contest the validity of the OBR estimates, he underlines the high levels of uncertainty related to these estimates.

The paper by Lineskova and others suggest that under the lower migration scenario to “keep the government budget balanced, the effective labour income tax rate has to be increased by 2.2 percentage points”. Again, this refers to estimates for 2060.

Both studies come to similar conclusions – that lower levels of net migration will impose greater pressure on national debt over GDP. This effect is just the result of faster ageing of the population with lower levels of net migration, and corresponds with standard economic thinking.

Why the different implications? There is agreement on the general economic effects of higher net migration in both studies: that conclusion is that higher levels of net migration lead to higher GDP per capita and lower net debt as a share of GDP. Where there is disagreement is about the need or desirability of higher net migration.

Social impacts

The Lineskova makes a straightforward economic argument from this about the benefits of migration in maintaining an age structure which supports economic growth. They do not venture into providing policy prescriptions and accept that their analysis does “not take into account the potential social impacts of higher migration”.

Rowthorn, however, emphasises that it may be preferable to have lower levels of migration even at the expense of faster ageing. He suggests that the levels of migration required to increased GDP per capita or lower future public debt are so high that their social impacts may outweigh the positive economic benefits. He points to potential problems such as overcrowding of public facilities (including schools, hospitals, roads), limited supply of housing and strain on natural resources (for example water) as additional reasons for preferring lower levels of migration.

This goes back to the essence of the migration debate in the UK. Economic estimates are important, but limited in that they cannot resolve important judgements about the type of society people want. These preferences over the “sort of place we want to live in” can drive people’s views and choices on migration just as much as the “pure” economic factors.

Meet the hot, funny, carefree Cool Mums – the maternal version of the Cool Girl

As new film Bad Moms reveals, what the cool girl is to the diet-obsessed prom queen, the cool mum is to the PTA harpy.

I suppose we should all be thankful. Time was when “mum’s night off” came in the form of a KFC value bucket. Now, with the advent of films such as Bad Moms – “from the gratefully married writers of The Hangover” – it looks as though mums are finally getting permission to cut loose and party hard.

This revelation could not come a moment too soon. Fellow mums, you know all those stupid rules we’ve been following? The ones where we think “god, I must do this, or it will ruin my precious child’s life”? Turns out we can say “sod it” and get pissed instead. Jon Lucas and Scott Moore said so.

I saw the trailer for Bad Moms in the cinema with my sons, waiting for Ghostbusters to start. Much as I appreciate a female-led comedy, particularly one that suggests there is virtue in shirking one’s maternal responsibilities, I have to say there was something about it that instantly made me uneasy. It seems the media is still set on making the Mommy Wars happen, pitching what one male reviewer describes as “the condescending harpies that run the PTA” against the nice, sexy mummies who just want to have fun (while also happening to look like Mila Kunis). It’s a set up we’ve seen before and will no doubt see again, and while I’m happy some attention is being paid to the pressures modern mothers are under, I sense that another is being created: the pressure to be a cool mum.

When I say “cool mum” I’m thinking of a maternal version of the cool girl, so brilliantly described in Gillian Flynn’s Gone Girl:

“Being the Cool Girl means I am a hot, brilliant, funny woman who adores football, poker, dirty jokes, and burping, who plays video games, drinks cheap beer, loves threesomes and anal sex, and jams hot dogs and hamburgers into her mouth like she’s hosting the world’s biggest culinary gang bang while somehow maintaining a size 2, because Cool Girls are above all hot.”

The cool girl isn’t like all the others. She isn’t weighed down by the pressures of femininity. She isn’t bothered about the rules because she knows how stupid they are (or at least, how stupid men think they are). She does what she likes, or at least gives the impression of doing so. No one has to feel guilty around the cool girl. She puts all other women, those uptight little princesses, to shame.

What the cool girl is to the diet-obsessed prom queen, the cool mum is to the PTA harpy. The cool mum doesn’t bore everyone by banging on about organic food, sleeping habits or potty training. Neither hyper-controlling nor obsessively off-grid, she’s managed to combine reproducing with remaining a well-balanced person, with interests extending far beyond CBeebies and vaccination pros and cons. She laughs in the face of those anxious mummies ferrying their kids to and from a multitude of different clubs, in between making  cupcakes for the latest bake sale and sitting on the school board. The cool mum doesn’t give a damn about dirty clothes or additives. After all, isn’t the key to happy children a happy mum? Perfection is for narcissists.

It’s great spending time with the cool mum. She doesn’t make you feel guilty about all the unpaid drudgery about which other mothers complain. She’s not one to indulge in passive aggression, expecting gratitude for all those sacrifices that no one even asked her to make. She’s entertaining and funny. Instead of fretting about getting up in time to do the school run, she’ll stay up all night, drinking you under the table. Unlike the molly-coddled offspring of the helicopter mum or the stressed-out kids of the tiger mother, her children are perfectly content and well behaved, precisely because they’ve learned that the world doesn’t revolve around them. Mummy’s a person, too.

It’s amazing, isn’t it, just how well this works out. Just as the cool girl manages to meet all the standards for patriarchal fuckability without ever getting neurotic about diets, the cool mum raises healthy, happy children without ever appearing to be doing any actual motherwork. Because motherwork, like dieting, is dull. The only reason any woman would bother with either of them is out of some misplaced sense of having to compete with other women. But what women don’t realise – despite the best efforts of men such as the Bad Moms writers to educate us on this score – is that the kind of woman who openly obsesses over her children or her looks isn’t worth emulating. On the contrary, she’s a selfish bitch.

For what could be more selfish than revealing to the world that the performance of femininity doesn’t come for free? That our female bodies are not naturally hairless, odourless, fat-free playgrounds? That the love and devotion we give our children – the very care work that keeps them alive – is not something that just happens regardless of whether or not we’ve had to reimagine our entire selves to meet their needs? No one wants to know about the efforts women make to perform the roles which men have decided come naturally to us. It’s not that we’re not still expected to be perfect partners and mothers. It’s not as though someone else is on hand to pick up the slack if we go on strike. It’s just that we’re also required to pretend that our ideals of physical and maternal perfection are not imposed on us by our position in a social hierarchy. On the contrary, they’re meant to be things we’ve dreamed up amongst ourselves, wilfully, if only because each of us is a hyper-competitive, self-centred mean girl at heart.

Don’t get me wrong. It would be great if the biggest pressures mothers faced really did come from other mothers. Alas, this really isn’t true. Let’s look, for instance, at the situation in the US, where Bad Moms is set. I have to say, if I were living in a place where a woman could be locked up for drinking alcohol while pregnant, where she could be sentenced to decades behind bars for failing to prevent an abusive partner from harming her child, where she could be penalised in a custody case on account of being a working mother – if I were living there, I’d be more than a little paranoid about fucking up, too. It’s all very well to say “give yourself a break, it’s not as though the motherhood police are out to get you”. Actually, you might find that they are, especially if, unlike Kunis’s character in Bad Moms, you happen to be poor and/or a woman of colour.

Even when the stakes are not so high, there is another reason why mothers are stressed that has nothing to do with pressures of our own making. We are not in need of mindfulness, bubble baths nor even booze (although the latter would be gratefully received). We are stressed because we are raising children in a culture which strictly compartmentalises work, home and leisure. When one “infects” the other – when we miss work due to a child’s illness, or have to absent ourselves to express breastmilk at social gatherings, or end up bringing a toddler along to work events – this is seen as a failure on our part. We have taken on too much. Work is work and life is life, and the two should never meet.

No one ever says “the separation between these different spheres – indeed, the whole notion of work/life balance – is an arbitrary construct. It shouldn’t be down to mothers to maintain these boundaries on behalf of everyone else.” Throughout human history different cultures have combined work and childcare. Yet ours has decreed that when women do so they are foolishly trying to “have it all”, ignoring the fact that no one is offering mothers any other way of raising children while maintaining some degree of financial autonomy. These different spheres ought to be bleeding into one another.  If we are genuinely interested in destroying hierarchies by making boundaries more fluid, these are the kind of boundaries we should be looking at. The problem lies not with identities – good mother, bad mother, yummy mummy, MILF – but with the way in which we understand and carry out our day-to-day tasks.

But work is boring. Far easier to think that nice mothers are held back, not by actual exploitation, but by meanie alpha mummies making up arbitrary, pointless rules. And yes, I’d love to be a bad mummy, one who stands up and says no to all that. Wouldn’t we all? I’d be all for smashing the matriarchy, if that were the actual problem here, but it’s not.

It’s not that mummies aren’t allowing each other to get down and party. God knows, we need it. It’s just that it’s a lot less fun when you know the world will still be counting on you to clear up afterwards.
