To fix the housing market, the government needs to do nothing at all

Just stop trying.

In November, planning minister Nick Boles tackled the country's housing crisis — caused, he said, by a decade-long invasion of propertyless aliens — head-on, announcing he would seek powers to build 100,000 homes a year on Green Belt land. Shortly afterwards, Theresa May, the Home Secretary, reinforced this message, warning us of the imminent danger that migrant homebuyers pose to the “national interest” – "without the demand caused by mass immigration," she said, "house prices could be ten per cent lower over a twenty year period."

The Conservative grassroots, mortified at what they apparently see as the sheer illiberality of building on the Green Belt, moved swiftly to an ostrich position to undermine the proposal.

"The notion of a housing shortage in London… is, and always has been, a myth," read Andrew Lilico's riposte. "Surpluses of dwellings over households actually increased everywhere".

It is almost impossible to be more wrong. The immigration argument has been debunked so comprehensively that, in its 2012 report on the housing shortage (pdf), the IEA casually dismisses it as an "oft-repeated non-issue". Similarly, the effort to use simple mathematics to describe a notoriously variegated and illiquid asset class ignores the fact that neither property nor its occupants are homogenous and freely exchangeable: an abundance of one- or two-bedroom flats in a given area at a range of prices, for example, is useless if the majority of demand is for family homes (pdf).

There is, in fact, a fairly robust consensus across the political spectrum that the United Kingdom is in the grip of an acute housing supply shortage with many causes, among them NIMBYism, speculation, capital flight from southern Europe, over-taxation, land use controls, and failure to implement comprehensive welfare reform. In the absence of a credible policy proposal from the Coalition, however, the left has assumed the mantle of leadership on the issue by setting itself in diametrical opposition to austerity, demanding more central government funding for affordable housing – and lots of it.

Unquestionably, the money could be put to good use. Shelter, the housing charity, predicted in 2010 that (pdf):

"cuts to housing benefit and the slashing of the affordable house building subsidy will be devastating for the housing aspirations of thousands of young people consigned to increasing costs."

Those costs are the third-highest in Europe, 40 per cent of net income for over 15 per cent of the population. Sensing the undercurrent of popular anger, Labour has promised funding for the same 100,000 homes a year as Nick Boles – except these are “affordable” ones. Unfortunately, these counterproposals only draw battle-lines for the next election. They address the question of how taxpayers should step in to reinforce the safety net, but do nothing to tell us how to rein in the cost of the safety net itself.

The key question is this: would building more “affordable housing”, either in the Green Belt or in our cities, actually end the housing crisis? In my view, probably not. Housing was a risky enough business before the recession; today, with scarce financing, high material costs, narrow profit margins, and downward pressure on public finances for the next decade at least (£), developers face additional disincentives. If anything, affordable housing prevents developers from meeting market demand while concurrently increasing their costs — and as such it has become a significant part of the supply problem.

Many English councils mandate that developers designate a certain proportion of units in any new construction as "affordable," i.e. earmarked for social tenants or a social housing provider. Taking the London borough of Newham as an example, that locality aims to provide "the maximum reasonable amount of affordable housing when negotiating on (the approval of) individual private residential and mixed use schemes". By “reasonable,” however, Newham means 50 per cent of the total, with the affordable component supported mostly by government subsidies.

This has serious implications on any proposed scheme's economic viability. Without government grants, affordable housing in Newham is completely uneconomic at the 50 per cent target (pdf) and remains so even at lower targets, for example with 35 per cent or 25 per cent provision. Viability is further impaired where build cost per square metre rises (as occurs when a development is denser) or sale price per square metre falls (meaning the proposed unit would be affordable in a free market). To wit, the economic viability of housing schemes in England is low if you intend to build units that constitute ordinary working- and middle-class housing in most of the English-speaking world, because local planning policies force developers to only embark on those projects which realise relatively higher marginal returns and command a higher market price.

This is a fact of which local governments around the country are aware (pdf); Newham's viability assessment, for example, points out that "50% affordable housing is unlikely to be viable in all market conditions", and that "in some circumstances... sales values would need to increase beyond the 2007 peak for 50% affordable housing to be achievable."

But this is not 2007, and we would be mistaken to believe that the social housing crisis is separable from the supply problem in the wider private markets. British social housing policy is itself heavily reliant on private sector provision; a crisis in one begets a crisis in the other, or as put by the IEA (pdf):

If social housing in Britain is under strain – and it clearly is – it is because the housing market as a whole is under strain.

When we consider that fully 20 per cent of the nation's residential property is directly or indirectly supported by the state and virtually the entire private sector housing supply process — design, location, construction, profit margin, and post-completion tenant allocation — is regulated and made more burdensome by the state, it does not take much to see that virtually all state intervention in the UK housing market should in theory, and does in fact, constrain supply or inflate demand. Certain aspects of the problem arise from pet policies of the right; others, of the left. What they have in common is that they disincentivise new housebuilding while making existing housing more expensive at the same time, to the detriment of low- and middle-income earners, the propertyless and the young.

Neither redistributive taxation nor piecemeal tinkering are well-suited to solve this problem. An iconoclastic, no-holds-barred programme of liberalisation, however, is. Like fuel shortages in the America of the seventies or bread shortages in the USSR of the eighties, the British housing crisis is government-led. If the government is serious about solving it, the first thing it should do is get out of the way.

Vote Leave have won two referendums. Can they win a third?

The Remain campaign will hope that it is third-time unlucky for Vote Leave's tried-and-tested approach.

Vote Leave have launched a new campaign today, offering a £50m prize if you can guess the winner of every game at the Euros this summer. They’ve chosen the £50m figure as that is the sum that Vote Leave say the United Kingdom send to the European Union every day.

If you wanted to sum up Vote Leave’s approach to the In-Out referendum in a single gimmick, this is surely it, as it is deceitful – and effective. The £50m figure is a double deception – it’s well in excess of what Britain actually pays, and your chances of winning are so small they can only be viewed through an electron microscope. Saying that “the UK pays £50m to the EU” is like saying “I paid £10 for breakfast at Gregg’s this morning” – yes, I paid with a £10 note, but I got £8 back.  The true figure is closer to £26,000 a day.

But the depressing truth is that this sort of fact-free campaigning works – and has worked before. It’s the same strategy that Matthew Elliott, the head of Vote Leave, deployed to devastating effect, when he was head of the No to AV campaign, and that Dominic Cummings, head of strategy at Vote Leave, used when he was in charge of the anti-North East Assembly campaign: focus on costs, often highly-inflated ones, and repeat, over and over again.

This competition is a great vessel for that message, too, with the potential to reach anyone who has at least one Facebook friend with an interest in betting or football, i.e. everyone. And as my colleague Kirsty Styles revealed yesterday, this latest campaign is just one in a series of Internet-based, factually dubious campaigns and adverts being used by Vote Leave on the Internet.

The difficulty for the opponents of No2AV was, as one alumni of that campaign reflected recently, “how do you repudiate it without repeating it?”. A row over whether the United Kingdom sends £50m or £26,000 – itself £1,000 higher than the average British salary – helps the Leave campaign whichever way it ends up.

Neither Yes to Fairer Votes or supporters of a devolved assembly for the North East ever found a defence against the Elliott-Cummings approach. Time is running out for Britain Stronger In Europe to prevent them completing the hattrick.
