Case-Shiller OFHEO faceoff

Two readers generously offered their valuable insights on the Case-Shiller OFHEO gap I noted earlier this morning.

Professor Nunes says that the CS index puts too much weight on particular regions. He has a paper showing how Case-Shiller and OFHEO agree much more region-by-region.

It looks like he has an important and very useful point. (I must also confess that he sent me the paper last fall, and I failed to remember his contribution).

Does the regional aggregation issue explain whether which series is right about January: OFHEO suggests we hit bottom and CS suggests that we're still going down? (Note: Professor Nunes does not like national (as opposed to regional) analysis of housing, so he may be understandably unwilling to answer). Note that OFHEO said that nearly all regions (the West being a notable exception) increased in January.

Sean MacLeod of Metacapital Management emails that "those in the mortgage finance market believe the OFHEO data to be c#$p." He prefers Case-Shiller and a third series, RadarLogic.

I am not sure CS is so much better. In particular, CS says that national housing prices almost doubled (relative to construction costs!) during the boom, which seems reasonable for a couple of regions, but a huge exaggeration for most of America. On the other hand, the OFHEO index was late in showing the bust (see the chart below, which measures both relative to the residential construction PPI). That's why I look at both, and support the Employment for Economists Act!






Many thanks to Mr. MacLeod and Professor Nunes! Housing prices are an incredibly important economic indicator these days, so their insights are worth many times more what I and the readers of this blog are paying for them!

Case-Shiller disagree with OFHEO

Earlier this month, the OFHEO calculated that housing prices rose significantly from December 2008 to January 2009.

Today, S&P reports that its Case-Shiller housing price index fell significantly (close to three percent) over that same time frame!

To further the Employment for Economists Act, a Commission of economists should be created to study why the two indices give different results. (The OFHEO has already explained how some of its ingredients are different, but that has yet to translate their exposition of recipes into an explanation of why Case Shiller has fallen so much more.)

Consumption and Personal Income News not So Good

The media reports that consumption spending rose in February for the second straight month, but they are referring to nominal consumption. Real consumption (as well as real personal income) fell. The only good news I see from today's personal income report is that February real consumption is still above the December 2008 lows -- that is, the big January increase was not entirely reversed (alternatively, there was some truth to the January measure).

[Last month, somebody asked where to see the BEA releases: go to www.bea.gov and look in the upper right corner].

Will the Geithner-Summers plan solve an ownership externality?

Another hypothesis about the banking crisis is that there is an externality -- certain critical institutions harm the wider economy when they hold mortgage assets, but each in its decision to hold them considers only its own costs and benefits.

I guess the story is: a bank owner thinks a pool of mortgages is worth $10 million, but owning those mortgages makes the bank excessively cautious, which somehow harms the wider economy. So the wider economy would like to see the mortgages sold to an institution whose caution would be less harmful, even if the less harmful institution valued the pool at just $5 million. But the bank owner refuses to sell for less than $10 million, so the bank owner keeps the pool and its caution.

A simple subsidy will not solve the problem. Suppose that the government said that it would pay for $5 million of the purchase price. Then potential buyers whose ownership would be less harmful to the wider economy would be willing to pay $10 million ($5 million for the pool itself and another $5 million for the government subsidy). But the subsidy also increases the valuations of the institutions whose ownership of mortgages is harmful to the wider economy. So if the harmful owners placed the highest value on these assets without the subsidy, they would do the same with it.

Nothing about the Geithner-Summers plan gives an incentive to mortgage assets to be ultimately held by the "right" institution. It only gives money to banks and creates a flurry of transactional activity, without changing the real ownership pattern that supposed created the problem to be solved.

Will the Geithner-Summers plan solve the Lemons problem?

One hypothesis about the banking crisis is that a secondary market for mortgages "does not now exist" (quote from Mr. Geithner's oped introducing the plan) because there is a "lack of clarity about the value of these legacy assets [which makes] it difficult for some financial institutions to raise new private capital on their own." (quote from U.S. Treasury fact sheet).

I guess the story is: a bank owner thinks a pool of mortgages is worth $10 million, and therefore refuses to sell for less than that. Potential buyers of that pool think it is worth $5 million, and therefore refuses to buy for more than $5 million. The market does not exist because the sellers value the assets less than potential buyers do.

A simple subsidy will not solve the problem. Suppose that the government said that it would pay for $5 million of the purchase price. Then potential buyers would be willing to pay $10 million ($5 million for the pool itself and another $5 million for the government subsidy). The problem is that the bank owner (presumably aware of the subsidy) may not want to sell for less than $15 million. The reason is that he might be able to buy the pool from himself -- in which case he would pay $10 million for the asset (that's what he thinks it is worth) and another $5 million for the subsidy. So if he can sell to himself for $15 million, why should he sell to another buyer who will pay only $10 million?

You might say that the Treasury or FDIC would not allow a sham transaction like I just described. Well then you are saying that the Treasury or FDIC will micro manage things -- good luck with that!

The Geithner-Summers plan is more complicated than the simple subsidy described above. But my intuition is that even the complicated version misses the point that a subsidy raises every one's valuations of the item subsidized, rather than (as supposed needed) raising the valuations of some relative to the valuation others. Thus, the Geithner-Summers plan looks like giving taxpayer money to banks and creating a flurry of activity without really changing any of the fundamentals (reminiscent of what I wrote last fall about the Paulson plan).

Commenters: do you know of anyone who has worked out an explicit lemon's model and then added the Geithner-Summers plan to it?

Housing Market Evidence Continues to Pile Up

The AP reports:

"The Commerce Department says sales rose 4.7 percent in February to a seasonally adjusted annual rate of 337,000 from an upwardly revised January figure of 322,000."

This adds to the growing list of reasons why the housing market is turning around in early 2009.

Oh yeah, we have to add that building permits increased in February too.

A Good Sign from Outside the Housing Sector

The Commerce Department says:

"New orders for manufactured durable goods in February increased $5.5 billion or 3.4 percent to $165.6 billion, the U.S. Census Bureau announced today. This increase follows six consecutive monthly decreases, including a 7.3 percent January decrease. Excluding transportation, new orders increased 3.9 percent. Excluding defense, new orders increased 1.7 percent."

A Trojan Horse for Green Cards


Eddie Meek points me to this WSJ article, which suggests that, in order to raise housing prices, Green Cards should be given to foreigners who buy a home in the U.S. At its best, the proposal is a Trojan horse for opening the gates to immigration.

Edward Glaeser has effectively argued that, thanks to a housing “bubble,” we have too much housing and are better off by adjusting to that reality rather than introducing a subsidy or trying schemes to temporarily and artificially bolster housing demand. On these terms, it might seem that the cards-with-houses proposal is another attempt to avoid taking needed medicine.

However, the flip side of “too much housing” is too few people to live in the houses. From some perspectives, America has had, and continues to have, too few people. Skilled immigrants add much to our economy and society. They are often leaders, for example, in patenting and starting businesses. Yet we still severely restrict their entry into the United States.

A perennial concern is that our neighborhoods might not be able to absorb many immigrants without some turmoil. But these are not normal times. Many neighborhoods have homes that are in need of occupants, so if there were ever a good time to distribute more green cards, this may be it.

However, the cards-with-houses proposal is not just about cards, and therein lie its weaknesses: It proposes to tie the green card to a housing purchase. As a result, the proposal is excessively interventionist and, compared with the simpler alternative of just distributing more green cards, would not achieve its desired effect (raise housing prices).

If green cards were sold without housing-purchase conditions, that would bolster housing demand and (in the short run, before additional housing might be built to accommodate the extra demand) therefore prices. The reason is that foreigners working in the United States (that’s the purpose of the green card — to make it easier to work here) need to live somewhere in the United States.

Adding a housing purchase condition to green card distribution, and wiping out the old means for obtaining green cards, would not bolster housing demand. It would only reduce the willingness of skilled immigrants to seek a green card. With the extra condition, immigrants would have to either buy a house that they would have purchased anyway (see above), or turn around and rent or sell the housing in the case that they do not really want to own one. Either way, housing demand would be unaffected.

As with many well-intentioned policy proposals, the cards-with-houses policy quickly degenerates into government micro-management. The authors of the proposal recognize the resale problem, and think they can “solve” it by having government authorities watch for several years to make sure that the immigrants still own, and do not rent out, the houses they have purchased. But as everyone in New York knows from witnessing (or partaking in) rent control cheating, it is quite difficult to police who lives in which house.

The simpler and more efficient alternative is to drop the house-purchase requirement — just distribute more green cards to skilled foreigners — and trust that immigrants have to live somewhere and will thereby bolster housing demand.

Cards-for-houses might be politically more feasible because it more explicitly leverages the housing crisis to increase immigration — an increase that would make sense (but lack political support) even without a housing crisis. I cheer for the Greeks in the Iliad, but are Trojan horses a necessary part of our democracy? Acting as if our political system is so dishonest that worthwhile goals can be achieved only by poorly executing ill-advised surrogate ones is not a good way to start someone’s time in the United States.
