John Stossel is jumping to Fox Business

John Stossel, the ABC anchor known for his libertarian bent, is moving to the Fox
Business Network to host a weekly prime-time program. He will also make
regular appearances on the Fox News Channel.

…Mr. Stossel will start work in October, and his weekly program,
named “Stossel,” will begin sometime in the fourth quarter. Fox said
“Stossel” would include news segments and conversations about
“libertarian issues in the United States and abroad,” including
free-market economics and civil liberties.

In a post on his ABC
blog, Mr. Stossel said he wanted to “dig into the meaning of the words
‘liberty’ and ‘limited government’ ” on the program.

“ABC enabled me to do some of that, but Fox offers me more air time and a new challenge,” he added.

The story is here.  I thank Yana for the pointer.

Department of Duh

Justin, a loyal MR reader, writes to me:

Funny
new story
. Near the end it mentions citizen's group that wants to
remove cameras from a highway because, in their words, "It's nothing
but a speed tax".

I liked the opening paragraph of the piece:

A driver has racked up dozens of speeding tickets in photo-radar zones on Phoenix-area freeways while sporting monkey and
giraffe masks, and is fighting every one by claiming the costumes make
it impossible for authorities to prove he was behind the wheel.

Monkey masks I can see.  But giraffe masks?  That's good enough for a markets in everything.  Who, other than this guy, buys a giraffe mask?  And how is this for governmental wisdom?

…It took Arizona state police months to realize the same driver was involved

And the guy's car?

…has black-and-white checkered racing stickers on its sides and a sticker on the windshield that reads "Bucktooth Racin'."

The state now has surveillance photos of him putting on a mask before driving but vonTesmar, the driver, offers up a novel defense:

…[he] said if the Department of Public Safety
does have surveillance photos of him on the road, it proves he's not a
danger to other drivers. If he were, officers would have pulled him
over, he said.

The cameras remain unpopular in Arizona:

Arizonans have used sticky notes, Silly String and even a pickax to sabotage the cameras.

Many
believe the shooting death of speed-enforcement van operator Doug
Georgianni on April 19 on a Phoenix freeway was a result of anger over
the cameras, although authorities haven't made that direct allegation.

Three separate citizens groups are targeting the cameras in initiatives for the 2010 ballot.

As you can see, the local government blogging marathon continues.  Soon I'll offer up some posts on crime.

Tax fiscalization as another cause of suburban sprawl

This hypothesis has its own paper, by Robert Wassner and David Edwards.  Here is the bottom line:

The more land use decisions in a state are driven by fiscal considerations, the more likely may be the degree of sprawl observed in the state’s urban areas. The reason is that outlying local governments in an urban area, with a greater likelihood of possessing undeveloped land, are more likely to use revenue considerations in choices related to land use. As discussed next, the extent that outlying local governments in a state’s urban areas weigh fiscal considerations in land use decisions is expected to depend on the relative reliance by local governments in the state on the different possible forms of local revenue. That is, greater statewide reliance on a form of local revenue that rises and falls with differences in land use choices can result in forms of land use decisions in an urban area that generate greater sprawl. The theoretical connection between sales tax reliance by local governments in a state and greater urban decentralization centers on the ability of local government officials to influence the location of retail activity in an urban area. The amount of overall retail activity in an urban area is determined by factors such as population, income, age distribution, etc. in the region and is unlikely to change due to local government influences. But local land use decisions can shape the distribution of overall retail development in an urban area. Local this land for retail activity if local greater retail generates for them. This surplus comes in the forms of (1) non-residents paying local sales taxes and (2) the lower alternate land uses.

The paper offers a good bit of evidence, though the authors are very careful to claim this is not the only or even the major factor behind sprawl.  Lots of little local governments, of course, also enhance educational competition and the quality of the local schools, which further encourages sprawl.

The myth of “no zoning” in Houston

I found this Michael Lewyn paper very interesting.  Here is his bottom line:

In fact, Houston regulates land use almost as intricately as cities with zoning by mandating suburban-style low densities, ordering businesses to hide their stores behind an asphalt ocean of parking, encouraging segregation of land uses, and forcing pedestrians to cross wide streets and to trudge through long, intersection-free blocks to go from one place to another. These policies have helped to make Houston as sprawling and automobile-dependent as other American cities (if not more so). By reversing such policies, Houston and other municipalities with similar policies can create an America that is both more deregulated and less sprawling.

It's a good paper.

How much will denser suburbs help the environment?

John Thacker points us to a study of California (registration required, but free).  I've only browsed it but the introduction states:

In September 2008, the California state legislature passed the first state law (Senate Bill 375) to include land use policies directed at curbing urban sprawl and reducing automobile travel as part of the state’s ambitious strategy to reduce greenhouse gas (GHG) emissions. The legislature recognized that cleaner fuels and more fuel-efficient vehicles would not be sufficient to achieve the state’s goal of reducing GHG emissions to 1990 levels by 2020. The bill requires the state’s 18 metropolitan planning organizations to include the GHG emissions targets established by the state Air Resources Board (ARB) in regional transportation plans, and to offer incentives for local governments and developers to create more compact developments and provide transit and other opportunities for alternatives to automobile travel to help meet these targets. ARB currently estimates that reductions in vehicle miles traveled (VMT) resulting from these actions will contribute only about 3 percent of the 2020 targets–an estimate that reflects uncertainties in the state of knowledge about the impacts of more compact development patterns on travel and the short time horizon involved.

In other words, the environmental benefits of checking pro-suburb subsidies are real, but they are smaller than many people think.  That's from the National Academy of Sciences and the authors are no haters of the environment.  If you check out p.59, you'll see that a forty percent increase in population density decreases vehicle miles traveled by less than five percent.  pp.131-132 offer a summary of the study's conclusions and quantitative estimates. 

The authors conclude that density-friendly policies are a good idea, and I agree, but still these are not overwhelming effects.  Keep in mind that current trends are strongly pointing toward population dispersion, so to reverse those trends and see greater density would take some doing.  We're not close to that margin.

There are many other interesting parts of the report, including case studies of Portland and Arlington.

First debug the child, then the computer

The idea of computers as liberators appealed to Silicon Valley philanthropists and Nicholas Negroponte could certainly tell a compelling story but, as Timothy Ogden explains, today the one laptop per child project seems to be in technical and financial trouble, the evidence that computers increase learning either in the classroom or at home is weak and the demand for the computers (as opposed to say cell phones (pdf)) in the developing world is low.  Meanwhile, simpler, cheaper approaches with proven evidence are not being fully exploited.  Here's Ogden.

The simplest and least costly of these programs is deworming. Nearly 2 billion people around the world are affected by parasitic worm infections, with children disproportionately affected. While each variety of parasitic worm affects a person differently, they all take a substantial toll on growth, energy and attention, with entirely predictable impacts on school attendance and learning. Harvard economist Michael Kremer has studied the impact of mass deworming in Kenya and India. Delivering deworming medication costs 50 cents per child per year in Kenya but yielded a 25 percent increase in school attendance; a similar program in India cost $4 per student per year and yielded a 20 percent attendance gain. "This is a simple, cost-effective and yet tragically not-done program. It's a scandal that [deworming] hasn't been addressed," Kremer says. There are spillover effects as well. "The most surprising thing about the study in Kenya was the widespread impact," Kremer says. The program drove down infection rates for several kilometers around the schools, he says, and there were significant improvements in attendance for untreated students, in the treatment schools as well as in nearby schools not in the program.

How much did highways really matter for suburbanization?

Following up on my earlier post, Dan Klein points my attention to the following piece by Wendell Cox, Peter Gordon, and Christian Redfearn, from Econ Journal Watch.  Excerpt:

Suburbanization has, for a long time, been a trend based on consumer preferences and larger trends, notably rising wealth and transportation and communications improvements (including the highways Baum-Snow investigates). Jackson (1985) finds U.S. suburbanization began at the end of the 19century. Indeed, he refers to “streetcar suburbs.” The 20th century U.S. experience is shown in Figure 1, which shows the percentage of US population living in metropolitan areas, and breaks that percentage down into central cities population and suburbs. The growth of the suburbs relative to the central city is seen well before 1950. Moreover, in the figure the relative decline of the central cities is understated because central cities have been annexing suburbs for many years.

The simple broad narrative is that, by and large, suburban living expanded throughout the twentieth century. Around the world, as incomes rise, people choose the mobility of the automobile; they overwhelmingly prefer the range and choice of personal transportation. As they choose automobility, origins and destinations disperse; and as these disperse, the attraction of the auto grows. It is a self-reinforcing cycle that is facilitated by better highways. But as with most public sector infrastructure developments, these usually follow rather than lead.

This article offers some striking facts.  Before the interstate highway system, the percentage of the U.S. population living in suburbs went from 7.1 percent in 1910 to 23.3 percent in 1950.  From 1950 to 2000 it had a smaller proportional increase, namely from 23.3 percent to 50 percent.

The central city of Copenhagen reached its population peak in 1950 and by 1990 had lost nearly 40 percent of its population; that is comparable to some of the highest losses in the U.S. Rust Belt.  The central city of Paris reached its peak population in 1920 and has lost one-quarter of its population by 1990.

There are many other interesting points in this piece.  I am not suggesting that highways do not matter, but the extent of the influence is maybe not as large as many people think.

The French carbon tax

France is finding is hard to pass a stiff carbon tax, though of course they already use lots of (non-carbon) nuclear power:

Details are finally emerging about the country’s planned “carbon tax,” to be put in place next year. And the idea is anything but popular.

The center-right French government wants to levy a tax of 14 euros per ton of carbon dioxide starting in 2010; carbon taxes are popular with many economists and business leaders because they are seen as easier to implement than carbon-trading plans, which France also belongs to.

In reality, France’s carbon tax is basically just a gasoline tax–and a tiny one at that. The electricity sector, overwhelmingly powered by emissions-free nuclear power, isn’t part of the plan [TC: Duh!], Prime Minister Francois Fillon told Le Figaro. The tax will basically fall on liquid fuels–raising pump prices 3 euro cents a liter (that’s roughly 15 U.S. cents a gallon).

In theory it will be revenue-neutral but most French voters are nonetheless opposed to the measure.  Here is further information:

Large CO2 emitters, such as oil refiners and steel makers, will be exempted from paying the new tax. The government will propose special compensations for fishermen, farmers and truckers…

Did highways cause suburbanization?

Via RortyBomb, that is a research paper by Nathaniel Baum-Snow.  Here is the abstract:

Between 1950 and 1990, the aggregate population of central cities in the United States declined by 17 percent despite population growth of 72 percent in metropolitan areas as a whole. This paper assesses the extent to which the construction of new limited access highways has contributed to central city population decline. Using planned portions of the interstate highway system as a source of exogenous variation, empirical estimates indicate that one new highway passing through a central city reduces its population by about 18 percent. Estimates imply that aggregate central city population would have grown by about 8 percent had the interstate highway system not been built.

You can quibble with the model specification but I accept the paper's general conclusion.  A few points:

1. I am reluctant to call this a subsidy without qualification.  Visit an old medieval city like Esternach, Luxembourg ("a formidable fortress erected by Count Siegfried in 963").  The main buildings are grouped together on a hill.  It's value-enhancing that later governments adopted policies, such as near-free trade and national defense, which eased those constraints and spread out the population.  I wouldn't say that the resulting population distribution of say Paris is best thought of as resulting from a subsidy because they're not all on top of a hill somewhere,  I would say it is the result of greater wealth and trade opportunities and law enforcement, with some element of subsidy.  So if you favor the construction of the interstate highway system, as I think most commentators do (try driving for long on Rt.1), it is a rhetorically loaded decision to invoke the word "subsidy" as the major mode of explanation.

2. Greater wealth, transport, and trade naturally cause people to seek out larger homes and greater living space.  In a world with no policy distortions this may well be the dominant effect in various long-run settings.  The rise of the suburbs is not all subsidy-driven by any means.

3. I recall the D.C. area quite well before it had either the Orange Line on the Metro (serving the Virginia suburbs) or Rt.66 going into Washington.  The construction of both enabled the suburbs to spread further westward.  But which was more important in driving this process?  Mass transit also can encourage suburbanization, especially the city has abominable public schools.  A longer and better Metro system — most of all with better parking — would have meant even more people moving to the suburbs.

4. Do not forget "white flight."  For American cities, this paper suggests that each black arrival lead to, on average, 2.7 white departures.  When it comes to DC, "black flight" has been a significant phenomenon and it is a major reason why the city has been losing population. 

5. Canada is much less suburbanized than is the United States and the greater "flight from blight" in the U.S. seems to be a major reason (see p.8 here).  When I think of U.S. suburbanization, I think of the failures of our municipal public sector as very important in this process.  In contrast, Fairfax County and Fairfax City governments are of reasonable quality.

6. For competitive Tiebout-related reasons, it is no accident that the public schools are so often better in the suburbs than in major cities.  Countries with strong social norms, such as Sweden, have this problem less.

7. One simple model (which I am not endorsing straight up) is that most American people with kids have a near-lexical preference for living in the suburbs.  Anything that enables them to do so can be called a cause of suburbanization and measured as such.  But isolating and measuring these marginal impacts, in the econometric sense, distracts us from seeing how general and how strong the underlying infra-marginal forces are and those are very often preference-based.

Conniptions coda

Last night one of my law students — who is also a realtor — informed me that many parts of northern Virginia do have a form of effective rent control.  Various apartment buildings have to set aside a certain percentage of their apartments for low-rent uses and try to attract people who receive housing subsidies.  He said this was true for Arlington but he wasn't sure about Fairfax County.  (This article suggests Fairfax County does have a similar program, with rent subsidies.  Although it does not state that the resulting rents are below market-clearing my student indicated that was true for Arlington County and also in Fairfax putting aside these apartments for low-income groups does seem to be a burden for the landlord.)  I wouldn't call this "stringent" rent control but it has effects much like those of rent control.  We should expect excess demand for those apartments, people masquerading as low-income when they are not, supplier reluctance to participate, and landlords who look for other ways of charging people for access to those apartments.  My student claims we do observe these phenomena and that the program is a mess.

Should I throw a conniption?

In any case I probably will, as I had once pledged, spend a few days soon blogging local issues only.  That's not a strict commitment; you'll still get Assorted Links and I'll break the truce if/when big news breaks elsewhere.

Recent trends in top income shares

You may recall that some time ago Alan Reynolds (Reynolds responds here) challenged the results of Piketty and Saez on rising income inequality in the United States.  There has now been a systematic look at biases in the data, with the goal being to reconcile data from the Current Population Survey with IRS measurements.  Burkhauser, Feng, Jenkins and Larrimore report their results:

Although the vast majority of US research on trends in the inequality of family income is based on public-use March Current Population Survey (CPS) data, a new wave of research based on Internal Revenue Service (IRS) tax return data reports substantially higher levels of inequality and faster growing trends. We show that these apparently inconsistent estimates can largely be reconciled once one uses internal CPS data (which better captures the top of the income distribution than public-use CPS data) and defines the income distribution in the same way. Using internal CPS data for 1967–2006, we closely match the IRS data-based estimates of top income shares reported by Piketty and Saez (2003), with the exception of the share of the top 1 percent of the distribution during 1993–2000. Our results imply that, if inequality has increased substantially since 1993, the increase is confined to income changes for those in the top 1 percent of the distribution.

An ungated version is here.  As I read this paper, the Piketty and Saez result, with some modifications for 1993-2000, basically holds up.  It's also worth noting that recent increases in inequality do relate mostly to the top one percent.  That's all for pre-crash times, of course.
