About this author:

WAS the housing bubble fueled by the belief that the world was running out of land? Almost certainly not; the housing bubble was fueled be speculative mania, and land scarcity was one of many explanations grafted on to the phenomenon by those looking to make or having just made a housing investment. But via Mark Thoma, we see Robert Shiller pursuing this argument:

Many people all over the world seem to have thought that since we are running out of land in a rapidly growing world economy, the prices of houses and apartments should increase at huge rates.

That misunderstanding encouraged people to buy homes for their investment value – and thus was a major cause of the real estate bubbles around the world whose collapse fuelled the current economic crisis...

But we do not really have a land shortage. Every major country ... has abundant land in the form of farms and forests, much of which can be converted someday into urban land. ...There are often regulatory barriers to converting farmland into urban land, but these barriers tend to be thwarted in the long run if economic incentives to ... become sufficiently powerful. It becomes increasingly difficult for governments to keep telling their citizens that they can’t have an affordable home because of land restrictions. ...

Many people seem to think that the US experience is not generalisable, because the US has so much land relative to its population. ... But, to the extent that the products of land (food, timber, ethanol) are traded on world markets, the price of any particular kind of land should be roughly the same everywhere. ...

As Mr Thoma says, you disagree with Mr Shiller's forecasts at your peril, but I'm not particularly fond of this explication. It strikes me as fairly un-economic. First point: all land is not created equal. The global economy is lumpy; economic activity concentrates in cities for very good economic reasons. Clumping reduces the time and cost to transmitting goods and people and ideas, for instance. This dynamic is one contributor to differences in home prices. It is more lucrative to be located in Manhattan than it is to be located in Des Moines. To get people to spread out and locate in areas that are less attractive economically, prices in the most desirable places have to increase.

How high? It's not clear, but it's worth pointing out that there is a lot of relatively undeveloped land in close proximity to some of the world's largest and richest cities. Prices might have to get very high indeed to push people away from job centres.

The other troublesome part of Mr Shiller's argument is the lack of acknowledgement of the opportunity costs of land development, which are substantial. Land is set aside for many reasons. Over æsthetic and preservationist concerns, for instance; Americans might one day find themselves developing the Grand Canyon, but presumably land prices elsewhere would have to be very, very high to make this happen. There are environmental concerns. Shifting acreage from forest to urban land has significant consequences at the local and global level—heat island effects, loss of carbon sinks contributing to warming, water run-off issues leading to contamination of drinking water supplies, and so on. For people to be willing to accept these costs, land prices would have be very high. And there are direct economic costs. People in cities have to eat. If you take land set aside for farming or ranching and convert it to land for living and working, then you reduce the supply of food and increase its price.

The point is this: if any increase in land cost quickly and directly undermined itself by incentivising the development of virgin land, then humanity would have long ago oozed across the whole of the habitable surface of earth—cities would not exist. Instead we see that land price increases are often sustainable, because all land is not created equal.

    Real Estate derives its value from its economic catchment basin, and has value relative to income available and perceived value as a positional good. 3:1 is the historical ratio in the US: nickgogerty.typepad.co...

    There is no liquidity for land deals. Speculation in land will not recover until investors and institutions begin lending against land again.

    When a client asks us for a land loan we ask them what they are planning to build. They have no answer that makes sense. The world does not need any more houses, offices, hotels, shopping centers or warehouses right now. When the buildings we have are full we will start lending money to people to build more, but not until then.

    Income is key. We have plenty of liquidity for stabilized income producing commercial properties but we are shunning land deals for now.

    Land is not created equally,but is valued by association with available water in any form ,such as aquifer,lake, stream ,river ,or rainfall.It is no accident that the main concern of Mars and our Moon is the presence of water.
    Available land is diminished by zelous enforcement of the Clean Water Act,The Endangered Species Act ,the BLM and local Zoning.

    Land is just manure and rotten plants over rock. to the extent that it is taxed to pay for lazy, overpaid government workers at a greater rate every year , then , land is a liabilty. It is human nature to load up on liabilities. That is why the stock market is going up now too.

    One should not discount the effect growing regulatory constraints will have on land available for development. In Illinois, most counties have adopted farmland preservation oridinances which will permanently put huge swaths of the state off limits to any type of development. Most oridances are so restrictive that the days when you could buy a small rural acreage and put a home on it are pretty well over. The state is also using a new septic ordinace to squash rural development. The new ordinance will not allow the surface discharge of effluent from a septic system (i.e. sand filter). This dramaticly reduces opportunities to create small rural subdivisions, especially in forested land where relatively impermeable clay soils predonimate. The intent is to force high desity development to parcels which are contiguous with metro areas where city sewer service is available, and even there development opportunities are limited due to farmland preservation initiatives.

    "But to the extent....the price of any particular kind of land should be the same everywhere." That friends is a textbook result, and if I had a teacher who preached that kind of nonsense he would hear some very non-academic language.

    [But we do not really have a land shortage. ]

    Flint, MI thinks it needs to raze about 40% of its housing.

    This is being hailed as a model for other areas of the country.

    Others will follow.

    But Ryan, the real opportunity now IS in farmland and ranch land. Prices are in decline in urban areas because there has been a bubble and the bubble has popped. Good Farm land though is becoming scarce as fewer and fewer large landowners buy up adjoining sections and build farm empires. That my friend is real wealth.

    Have you tried to acquire even a quarter section lately? Go try.

    Your city job security is really your risk too in my opinion. Owning a small city lot parcel of land is as close to being landless as I can imagine. What you want is agricultural property now and better yet if it is productive.

    You are right though that all land is not equal but in a commodity cycle like we are now experiencing it is unwise to hinge all your bets on urban property. No, they are not making new land. But they are not making a smaller population either. Location really will matter in the future. But city lots are not the place to be putting your money now.

    they're certainly not making it anymore, but Iam more convinced than ever that real estate has another 25% to fall, and best case, it is dead money for another five to ten years. The New York Times produced some insightful data on inflation adjusted home prices for the last120 years, which baselines at a $100,000 for a single family home in 1890. Few people realize how superheated the recent real estate bubble really got. Past bubbles very consistently peaked at $125,000 in 1896, 1979, and 1989. This last one peaked at $205,000 in 2005, almost double the previous record highs. And while we have dropped 34% since then, to $135,000, we haven't even fallen tothe past all time highs yet. If you look at historical lows, my call for a further 25% slump looks positively bullish. We saw lows consistently around$66,000 in 1920, 1932, and 1942. Postwar lows came in at $105,000 in 1976,1983, and 1996. These figures suggest the best case low is down a further 28%,and the worst case is down another 51%. I think I'll go find something else to trade.
