Home Economics Markets Do Actually Work - No, Really

Markets Do Actually Work – No, Really



Apparently building more houses doesn’t make housing more affordable. This is an impressive claim:

Yet the housing developments championed by Jenrick do nothing to increase the number of affordable homes. Developers don’t want to build cheap starter homes. They prefer five-bedroom, low-density housing – hence the hunger for greenfield sites, especially those near beauty spots, which are massively more profitable. Meanwhile developers shun available brownfield sites that CPRE estimates could support building 1m new homes.

Well, why are they more profitable? Because that’s the sort of housing that people want to buy because that’s the sort of housing people want to live in. Demand does have that little bit to do with prices, you know?

But think on a little more too. Say that the UK requires 25 million units of housing – not all that far off the truth given the 25 million-sh households. So, we build some more 5 bed rural homes. That means we’ve now got 25 million and three houses. This makes every house in the country that little bit cheaper.

Really, markets do work. Increasing supply into static demand reduces prices. Further, the more fungible the market the more it is the marginal unit that determines the average price.

Of course, we have something more complex here, changing demand and changing supply and it’s really a series of local markets with the national supply not being entirely and quite the point. But that just increases the necessity of taking markets into account. Localities where prices are high are exactly where we should be putting more houses. Because that’s where, by definition, demand is higher.

As to why this isn’t happening:

Ros Coward is professor emerita of journalism at Roehampton University

This doesn’t work as well as having the economists teaching journalism. On the grounds that you do have to know how to write to do economics but clearly, from the example on offer, you don’t need to know any economics to do journalism.



  1. I notice that he used the term “affordable housing” without parentheses or capital letters, so is he really arguing that developers are building houses no one can afford? If not, he’s doing a very good job at the journalism bit either.

  2. “Gentrification is a terrible thing” (rich people buying houses in poor neighbourhoods)

    “We shouldn’t build apartment buildings that only the wealthy can afford”.

    Some crazy people out there.

  3. According to the ever-reliable Wikipedia:-

    Rosalind Coward is a journalist and writer. She is an Emeritus Professor of journalism at Roehampton University, and a former member of the board of Greenpeace UK.

    ‘Nuff said?

  4. ‘cheap starter homes’
    There’s a problem right there:, it’s a ‘starter home’ because nobody really wants to live in it for long, it’s just a temporary abode until rising inflation and maybe a promotion makes the next rung of the ladder affordable. Starter homes, ‘affordable housing’; the slums of tomorrow.

  5. Britain has some of the smallest houses in Europe. But the greens want the average to be smaller.

    They really do want everyone to be miserable!

    (Except themselves. They live in nice big places if they can.)
