The greatest basketball team ever?

These Spurs are so quiet, but it should be asked whether they are the best NBA team to have walked on the planet Earth.  A few points:

1. Since 1997 they have a winning percentage of over .700, the best in any sport.  This includes two previous championship rings, but the current incarnation of the Spurs is believed to be the best.

2. They have absolutely crushed a variety of strong teams from the West, even when Tim Duncan had sore ankles.

3. Their best player, Tim Duncan, should at this point be MVP every year.

4. They are one of the best defensive teams, ever.  Bruce Bowen is a first-rate stopper.

5. They are one of the best-coached teams, ever.  They have an amazing variety of offensive plays and defensive set-ups.  They can play in many different styles, including run and gun fast break, when needed.  They are far more than the sum of their parts.

6. They do not appear to have problems with personalities or dissension.

7. They have a very strong bench.

8. You would rather have Manu Ginobili than Kobe Bryant.

9. In any sport where performance is measurable, quality rises over time.  Yes there is dilution but overall the best basketball teams are getting better.  And the use of foreign players — prominent on the Spurs — is overcoming the dilution problem rapidly.

Can you imagine Bruce Bowen holding MJ to thirty points and Duncan going around Bill Cartwright at will?  Could they keep the fast break of the Showtime Lakers in check, while exploiting the relatively weak defense of that team?  How would they match up against the 1989-1990 "Bad Boy" Pistons, or the Celtics with Bill Walton?

We should put the low TV ratings aside and start asking these questions.

Private Prisons and Government Contracting

Today, I will be debating the value of private prisons at the National Debate on Prisons and Punishment.  I intend to say the following:

1) Many studies (see also Changing the Guard) find that private prisons are cheaper than comparable public prisons.  Operating costs savings are a modest but not insubstantial, about 10-15 percent per year.

2) We should not be surprised that private prisons are
cheaper.  Mueller (2003), for example, looks at 71 studies
comparing public and private firms from Australian airlines, to German mail
delivery, to Indian manufacturers. In
only 5 of 71 studies were public firms found to be more efficient. In 56 studies private firms were
more efficient (the remaining studies found no difference).  Tellingly, the private firms were most efficient in the least regulated industries.

3)  Having said that, there are still potential problems with prison privatization and a puzzle that needs to be faced.  Prison privatization is really a misnomer.  What is really going on is contracting out and there at least two problems with contracting out.

a)  You get what you contract for. If the contract says cheaper prisons and nothing else – you will get cheaper prisons and nothing else. Contracts must cover quality as well as quantity.

Quality is not always easy to measure so contracting
out must be accompanied by investments in technology for contract monitoring
and output measuring. 

b)  In part as a reaction to the above problem there is the problem of governmentalization of the private sector.  Governmentalization occurs when the contract is written so that the private firm is restricted to duplicate the public firm, thus precluding innovation.  Some private prison contracts have gone so far as to detail the type of toilet paper to be used in the prison!

4) I think these problems can be addressed. For example, we should be contracting over outputs not inputs i.e. over the number of inmates who learn to read rather than the
provision of "reading programs."  (The British and Australians do this better than the U.S.)

Contracting out also requires an investment in technology for measuring outputs carefully. E.g.
recidivism rates.

With good contracting much more is possible from prison
privatization than lower costs including more innovation in prison management, better training
programs, reduced recidivism etc.

5)  But here is the puzzle.  If the reason for contracting out is that public prisons are run poorly, why should we expect government to do a better job at writing contracts?

I have some ideas on this but comments are open.

The end of upward mobility?

…two of the nation’s newspapers — The New York Times and The Wall Street Journal — are running extensive multipart series that paint a much darker picture.  The U.S., rather than being a land of opportunity, these stories argue, is increasingly a class-bound place of immobility and stratification, where it’s becoming ever harder for the people at the bottom to move up…

Rather than agonizing over relative comparisons, it may be better to concentrate on the simpler and intuitively satisfying concept of absolute "mobility," — whether you are doing better than your parents did, or whether the living standards of a whole group of people are rising over time.  From this perspective, there are signs that this past decade has had more upward mobility compared with the previous two decades…

There’s yet another big problem: we actually know very little about whether relative mobility increased or decreased during the New Economy decade because complete data don’t exist yet.  With a few exceptions, most studies stop with the mid- or late 1990s.

Here’s what we do know: Over the past decade, virtually every traditionally disadvantaged group made gains in absolute terms.  Take, for example, families headed by immigrants who entered the country in the 1980s.  The poverty rate for such families dropped sharply, from 26.6% in 1995 to 16.4% in 2003…Similarly, a combination of welfare reform and tight labor markets helped drive down the poverty rate for female-headed households with children from 46.1% in 1993 to 35.5% in 2003….it beats the total lack of progress in the previous decade.

That is from 20 June 2005, Business Week, by Michael Mandel.  Here is a new book on who gets ahead in low-wage labor markets.  Here is my previous post on Horatio Alger.  Here is my previous post on the family as a source of inequality.

Cereal Terrorism

The Wa Post has a good piece on how the administration’s terrorism statistics have been trumped up.  The article also sheds light on the workings of bureaucracy.  Here’s the most ridiculous example.

More than a year before the 9/11 attacks the FBI runs across some Arabs stealing Kellogg’s Cornflakes.  The FBI doesn’t give a damn about cornflakes so they let them go.  Sixteen months later come the attacks and now Arabs are hot property so the FBI rounds them up again, asks them a few questions about terrorism (making this a terrorism investigation), and charges them with conspiracy to possess stolen property.  No terrorism charges are ever filed but the three grocers remain on the federal list of successfully prosecuted terrorism cases.

For this we need the Patriot Act?

Rationality and war

"Until this message," Kissinger would write, "I had not taken Sadat seriously."  …Kissinger would come to understand that Sadat’s objective was to shock Israel into greater flexibility and restore Egypt’s self-respect so that he, Sadat, could be more flexible as well in order to achieve an agreement.  "Our definition of rationality did not take seriously the notion of starting an unwinnable war to restore self-respect," Kissinger would write.

That is from Abraham Rabinovich’s gripping The Yom Kippur War: The Epic Encounter that Transformed the Middle East

Capital gains, savings, and income

In response to my previous query, the ever-intelligent Arnold Kling writes:

For an individual, I am willing to count a capital gain as income. I am more or less indifferent between earning a capital gain and earning a dividend.

For a nation as a whole, to a first approximation I do not believe that a capital gain is possible. Suppose a corporation issues a bond, and a year later the market revalues the bond upward by 10 percent. It seems to me that the bond owners’ gain is the corporation’s loss. I think that is true in general for capital gains and losses in the economy–they net out.

Another way to arrive at the view that capital gains and losses ought to net out for the nation as a whole is to consider that national income equals national output. If a re-valuation of assets produces no output, then it produces no income. It seems to me that the ups and downs of financial assets are quite properly excluded from national income and therefore from national saving.

Read more here.  Catallarchy.net offers a similar perspective.

My take: I have no desire to overturn the conventions of national income accounting.  But this view still fuels the belief that our currently measured low savings rate does not matter much.  (Non-bubbly) capital gains imply high future output and possibly high future savings as well.  Let’s say you received news that manna would drop from heaven in five years’ time.  No this news is not "savings" but you still have something to eat in the future.

Let’s say the capital gains are bubbly and thus temporary.  Some people still are more liquid in the meantime (exam question: is anyone less liquid?  Do these liquidity losses offset the gains?).  Surely this should count for something, although not nearly as much as non-bubbly capital gains would count.

Can the Keynesian distinction between individual and social liquidity be used to create a new version of Hayekian business cycle theory?

Birdsong and human song

Here is a site on bird song, and yes I am recommending the actual music clips.  The slowed down versions sound like Miles Davis.  The accompanying book is excellent, and not only because you can read it in an hour.

If you want music by humans, try Lee Perry’s new four-CD collection I Am the Upsetter; it is the best Perry anthology (better than Arkology or Open the Gate, although buy all three) and therefore one of the best CDs sets, ever.

What Steve Levitt reads

Malcolm Gladwell "the greatest living storyteller" but has no interest in the rest of the magazine; reads Mr. Gladwell’s stuff online.

Yahoo Finance. "I handle my financial portfolio like it’s a big gambling account." Appreciates array of free info, and "when I started five years ago, it was better developed than others."

Three blogs by economists: MarginalRevolution.com by George Mason University professors Alex Tabarrok and Tyler Cowen, Berkeley professor Brad DeLong’s Semi-Daily Journal and the Becker-Posner Blog, by the U of C’s Gary Becker and U.S. Appellate Court Judge Richard Posner.

At bedtime, newsmagazines and People. "I can rarely convince myself that there are books worth reading. And at one point I became brainwashed by my father that it was unmanly to read fiction – so I read Time and Newsweek instead."

Markets in everything

It’s sold as a must-have accessory to give urban SUVs a whiff of the outback. But U.K. officials say drivers who use spray-on mud to avoid identification by police speed cams face hefty fines for obscuring their license plates.

Targeting self-conscious 4×4 owners whose rugged vehicles seldom see obstacles bigger than a speed bump, the enterprising British e-tailer behind Sprayonmud sells the scent of the countryside in a squirt bottle.

For 8 pounds (about $14.50), buyers get 0.75 liters (.85 quarts) of genuine filthy water, bottled from hills near the company’s premises on the rural England-Wales border. The aim, says the website, is "to give your neighbors the impression you’ve just come back from a day’s shooting or fishing — anything but driving around town all day or visiting the retail park."

"The mud is from Shropshire," said Sprayonmud proprietor Colin Dowse, a financial consultant who has been selling the product in the United Kingdom for 12 months. "It contains mud plus some secret ingredients to improve stickability so that it dries before it runs off the paintwork."

But, while the site promises SUV owners a route around social stigma flung by a growing anti-4×4 lobby, motorists of other stripes are thought to use the same technique to freely flout speed limits.

Tipsters in motoring forums advise canny drivers they can smear mud over their license plate to avoid detection by police speed cameras, which photograph plates’ registration details to ID lawbreakers using a national vehicle database. A few squirts of dirt, and snapped speeders would become as good as invisible.

Here is the full story, and thanks to Joseph Weisenthal for the pointer.  By the way, this example is too ridiculous to deserve its own installment of "Markets in Everything."

The Rise of Alex

The NameVoyager lets you type in a name and see the number of babies per million that name was given to from 1900 to 2003.  Below is Alex.  Note that the thickness, not the height, of the lines gives the relative use of that variant.

It’s unfortunate that the data only go as far forward as 2003 because obviously the popularity of Alex will have exploded after August 21 of that year.
