The high cost of poor land use

Over the weekend The Economist published an interesting article called, Space and the city: Poor land use in the world’s greatest cities carries a huge cost. The argument is that land isn’t scarce. It’s the land use policies we have created that are artificially limiting supply and driving up real estate values.

In fact, land is not really scarce: the entire population of America could fit into Texas with more than an acre for each household to enjoy. What drives prices skyward is a collision between rampant demand and limited supply in the great metropolises like London, Mumbai and New York. In the past ten years real prices in Hong Kong have risen by 150%. Residential property in Mayfair, in central London, can go for as much as £55,000 ($82,000) per square metre. A square mile of Manhattan residential property costs $16.5 billion.

And part of the reason this has become so prevalent is because of the shifts we’ve seen in our economy and the great return back to cities.

In the 20th century, tumbling transport costs weakened the gravitational pull of the city; in the 21st, the digital revolution has restored it. Knowledge-intensive industries such as technology and finance thrive on the clustering of workers who share ideas and expertise. The economies and populations of metropolises like London, New York and San Francisco have rebounded as a result.

So how do we get better at meeting real estate demand in our cities? The Economist has two suggestions.

One:

First, they should ensure that city-planning decisions are made from the top down. When decisions are taken at local level, land-use rules tend to be stricter. Individual districts receive fewer of the benefits of a larger metropolitan population (jobs and taxes) than their costs (blocked views and congested streets). Moving housing-supply decisions to city level should mean that due weight is put on the benefits of growth. Any restrictions on building won by one district should be offset by increases elsewhere, so the city as a whole keeps to its development budget.

Two:

Second, governments should impose higher taxes on the value of land. In most rich countries, land-value taxes account for a small share of total revenues. Land taxes are efficient. They are difficult to dodge; you cannot stuff land into a bank-vault in Luxembourg. Whereas a high tax on property can discourage investment, a high tax on land creates an incentive to develop unused sites. Land-value taxes can also help cater for newcomers. New infrastructure raises the value of nearby land, automatically feeding through into revenues—which helps to pay for the improvements.

These recommendations will probably be unsettling for a number of people. 

I would imagine that many communities would prefer to have planning and growth decisions happen bottom up, as opposed to top down. But I think there’s some truth to this recommendation and I don’t think it has to mean completely excluding bottom up feedback. Communities and individuals are naturally going to look out for their own self-interests. And so I think many would agree that there’s value in having a holistic urban strategy in place.

Recommendation number two pertaining to land value taxes is a loaded one. So I’m going to save my specific comments for a dedicated post on LVTs. 

But I will say that I don’t think trying to squeeze landowners into development via taxes is the most efficient and immediate way to address supply shortages. In advance of this, we should be examining the current barriers to development. Because we’re talking about hyper competitive global cities with perpetual supply deficits. And I don’t believe the problem is incentive-based. The problem is finding sites. The problem is finding ways to build.

What do you all think? This is an interesting topic of discussion.
