A Nuts and Bolts Example of Economies of Scale (or the Lack Thereof)

Mr. Bair said Boeing is working closely with its primary fastener supplier, Alcoa Inc., to get enough high-quality titanium bolts to put the plane together in a logical fashion. Nevertheless, major components, such as the wings, arrived from Japan and other locations such as Italy and South Carolina held together by thousands of temporary fasteners.

The unexpected lack of fasteners marks the sort of test Boeing will face in coming years as it moves to fill a press of orders for the 787 and other aircraft amid an aerospace boom.  . . .

. . .

Unlike previous airplanes, the Dreamliner is made largely of futuristic composites, which can’t be held together with traditional aluminum rivets. Instead, the major sections are bolted together with specially coated bolts that fit into brackets at each joint. Each bolt must be individually made on a lathe — a process that can’t be hurried. Because it takes time to set up the lathe, Alcoa would prefer to make thousands of one type of fastener before breaking the machine down and resetting it.

"Problem is, we don’t need thousands of bolts right now. We might need 10 of one kind," Mr. Bair said.

UNO Protects Students from Cupcakes (Whether They Want to Be Protected, or Not)

 

Many years ago, I went along with a group of Exec MBA students to Germany.  Among them was Bill Swanson.  Bill had a sense of humor.

At some point in the trip, I spilled ketchup on my tie.  Bill’s response was that normally a ruined tie would be sad, but given my tie, the ketchup was an improvement.

Yes, Bill has a sense of humor; so I’m hoping the story below is a joke.

That’s what I hope, but what I fear is that the story below is one more example of the inefficient, sometimes painful (like when an 8th grader can’t take aspirin to middle school), and sometimes funny, things that we are driven to do to protect ourselves from being sued, in an economy where congress has empowered personal injury lawyers to frequently sue for huge and unpredictable compensatory and punitive damages.  (When Joe Ricketts, Ameritrade founder, spoke to my Exec MBA class a few years ago, he said that the biggest threat facing the U.S. economy was the proliferation of tort law suits.)

So it’s either a bad joke; or (most likely) it’s UNO protecting itself against every potential law suit; or it’s a third, and worse, alternative—which would be if the story below is to be taken at face value. 

In that case we would have to conclude that some UNO staff have nothing better to do with their time than to paternalistically ‘protect’ young adults from a minuscule risk of illness from freely choosing to purchase and eat cupcakes being sold by fellow students to raise money for good causes.

 

Here is an excerpt from the page one, lead story, of the Sat., Oct. 6, 2007, Omaha World-Herald:

 

(p. 1A)  Guns. Drugs. Bake sales.

What do these things have in common?

All have been banned at the University of Nebraska at Omaha campus.

Citing safety and health concerns, UNO last week prohibited selling homemade food items at campus fundraisers.

Officials said the prevalence of serious food allergies and the potential for contaminated food — either by accident or deliberately — led UNO to adopt the policy, which then drew complaints from student groups.

"The primary issue is the health of the students and the safety of the students," said Bill Swanson, assistant to the vice chancellor in the Career Exploration and Outreach Office.

No one on the UNO campus has reported problems with contaminated food purchased at a bake sale, Swanson said.

But there have been incidents around the country, he said, and those were enough to prompt a discussion among officials.

The decision has come under fire from students who say the restriction cuts off small student (p. 2A) groups from their primary fundraising source.

The Public Relations Student Society of America traditionally held bake sales once a month to raise money for national conferences, local business luncheons and volunteer work, said the group’s president, Katie Dowd.

The group raised about $1,500 a year hawking homemade baked goods donated by members.

"It’s a big blow to us," said Dowd, who called the potential for food contamination from her group’s offerings "very unlikely."

Thales of Miletus Lives

 

   Source of book image:  http://store.43folders.com/books-3-1400063515-The_Black_Swan_The_Impact_of_the_Highly_Improbable

 

This is part entertaining rant and part serious epistemology.  I’ve finished 9 of 19 chapters so far–almost all of my reading time spent smiling. 

Historians of Greek philosophy used to tell the story of one of the first philosophers, Thales of Miletus, that he once was watching the stars, and fell into a well.  The citizens of Miletus made fun of him being an impractical philosopher.  To prove them wrong, he used his knowledge to corner the market in something, and made a fortune. 

Not a very plausible story, but appealing to us philosophers.  (Like Thales, we like to think we could all be rich, if we didn’t have higher goals.)

Well apparently Taleb is the real Thales.  He wanted to be a philosopher, got rich on Wall Street using his epistemological insights, and is now using his wealth to finance his musings on whatever he cares to muse on.

Beautiful!

 

Here’s an amusing sentence that broadened my grin.  (It was even more amusing, and profound, in context, but I don’t have time to type in the context for you.)

(p. 87)  If you are a researcher, you will have to publish inconsequential articles in "prestigious" publications so that others say hello to you once in a while when you run into them at conferences.

Buchanan on Hayek, Rawls and Nozick

In an earlier blog entry, I mentioned a comment on disagreeing with journal referees, made by  James Buchanan in conversation at the closing dinner of the 2007 Summer Institute for the Preservation of the History of Economics.

Hayek also came up at the dinner with Buchanan. Buchanan mentioned that he was not as enthused about Hayek’s later work, including The Fatal Conceit, and Law, Legislation and Liberty—he thought the best might have been The Constitution of Liberty.

He mentioned that some foundation had funded a couple of conferences in Europe of top free market scholars to offer advice to Hayek.  They told Hayek that his manuscript was a mess, and that it would be an embarrassment to him to publish it. But he said he was already under contract. (I think this comment referred to The Fatal Conceit.) So someone (Bruce Bartlett?) helped Hayek clean it up.

Buchanan also spoke highly about Rawls.  I think I mentioned that Hayek had said that his approach was similar to Rawls.  I think Buchanan said he did not think that comment was surprising.

I also believe I remember Buchanan saying that he thought more highly of Rawls than of Nozick.

 

Mugabe Driven by Quest for Power, More than from Paranoia, or Marxism: More on Why Africa is Poor

 

No one outside of Mr. Mugabe’s inner circle, of course, can say with certainty why he has pursued policies since 2000 that have produced economic and social bedlam. For his part, Mr. Mugabe says Zimbabwe’s chaos is the product of a Western plot to reassert colonial rule, while he is simply taking steps to fight that off.

Among many outside that circle, however, the growing conviction is that Zimbabwe’s descent is neither the result of paranoia nor the product of Mr. Mugabe’s longstanding belief in Marxist economic theory. Instead, they say, Zimbabwe is fast becoming a kleptocracy, and the government’s seemingly inexplicable policies are in fact preserving and expanding it.

. . .

Mr. Mugabe’s government declares currency trading illegal, but regularly dumps vast stacks of new bills on the black market, still wrapped in plastic, to raise foreign exchange for its own needs, business leaders and economists say.

The nation’s extraordinary hyperinflation, last pegged by analysts at 10,000 percent a year, is an economic disaster that, by all accounts, the government needs to address. Yet after it ordered merchants in July to slash their prices, cadres of policemen and soldiers moved into shops to enforce the new controls, scoop up bargains and give friends and political heavyweights preferential access to cheap goods.

. . .

Mr. Mugabe’s 25-bedroom mansion in Borrowdale, the gated high-end suburb of Harare, the capital, is the locus of a boomlet that has spawned luxury homes for government and party officials. (Mr. Mugabe said his mansion was built with goods and labor donated by foreign governments.)

Mr. Mugabe arrived to open Zimbabwe’s Parliament this month in a Rolls-Royce. Equally telling, the legislature’s parking lot was crammed with luxury cars.

Such riches have been accompanied by a steep decline in living standards for just about everyone else. The death rate for Zimbabweans under the age of 5 grew by 65 percent from 1990 to 2005, even as the rate for the world’s poorest nations dropped. Average life expectancy here is among the world’s lowest, according to the United Nations.

An Innovative Way to Reduce Global Warming, If We Need One

 

(p. B1) What if we wait too long to act on global warming? What if nothing we do is enough? Already, scientists are working up plans of last resort: stratospheric sprays of sulfur, trillions of orbiting mirrors and thousands of huge off-shore saltwater fountains.

Each is designed to counteract global warming by deliberately deflecting sunlight, rather than by retooling the world’s economy to eliminate carbon-rich oil, coal and natural gas.

Some scientists argue that such actions might be easier and relatively cheaper. Until recently though, whenever University of Maryland economist Thomas Schelling, recipient of a 2005 Nobel Prize, raised such geo-engineering ideas, "half the audience thought I was crazy and the other half thought I was dangerous," he said. As global temperatures rise and greenhouse-gas emissions accelerate, however, even wild ideas are becoming respectable.

. . .

Earlier this month, researchers at the Carnegie Institution of Washington, D.C., released the most precise computer studies yet evaluating the controversial sunshade idea. Their findings, reported in the journal Proceedings of the National Academy of Sciences, revealed that a last-ditch engineering effort to block sunlight could reverse global warming — at least temporarily. Indeed, it could lower average temperatures to levels not seen since 1900. "Every study we do seems to indicate it would work," said Carnegie climate modeler Ken Caldeira.

. . .

For Nobel laureate Schelling, the political advantages of geo-engineering outweigh its technical risks. It may be easier to launch a climate-control project than to persuade people all over the world to stop using fossil fuels. "It drastically converts the whole subject of climate change from one of regulation involving six billion people to a simple matter of a budgetary agreement about how to manage the modest cost," Prof. Schelling said. "I think geo-engineering is going to be the deus ex machina that will save the day."

Florence in Its Prime: Ghiberti’s “Gates of Paradise”

In my work on the labor economics of the process of creative destruction, I make use of the competition between Ghiberti and Brunelleschi over who would do the bronze door panels.  Brunelleschi withdrew, after a "tie" decision from the judges.  He then retooled, and bult the marvelous dome that is still one of the world’s architectural marvels.

 

If Michelangelo’s "David" heads the "must see" list of Renaissance masterpieces for most visitors to Florence, then I suspect "The Gates of Paradise," Lorenzo Ghiberti’s monumental doors of the Baptistery of San Giovanni, rank a close second. The 20-foot-tall portal — 10 exquisitely articulated gilt bronze reliefs of Old Testament scenes, framed by standing prophets, foliage and projecting heads — has mesmerized viewers since its completion in 1452. Michelangelo himself is supposed to have given the doors the name by which they are still known.

. . .

Next year, visitors to Florence will again see "The Gates" restored to their full splendor, permanently installed in the Museo dell’Opera del Duomo.

Congestion Pricing in NYC Will Reduce Traffic and Pollution

(p. A1)  ALBANY, June 7 — Mayor Michael R. Bloomberg’s plan to reduce traffic by charging people who drive into the busiest parts of Manhattan received significant support on Thursday as Gov. Eliot Spitzer endorsed the idea and the Bush administration indicated that New York stood to gain hundreds of millions of dollars if the plan were enacted.

If the measure is approved by the Legislature, New York will become the first city in the United States to impose a broad system of congestion pricing, which was introduced in London in 2003 and has been credited with reducing traffic there.

Governor Spitzer said he would work to ensure passage of the plan, which is a major part of the mayor’s blueprint for improving air quality and traffic flow for the next several decades. The Bloomberg administration has estimated that it could put the program into effect within 18 months of legislative approval.

With Right Incentives, Workers Make Better Tech Purchases Than Managers

 

(p. A7)  Corporate technology managers usually pick laptops, software and other technology for employees. Now some tech managers are finding workers can do a better job when they choose and buy the equipment themselves.

At KLM Royal Dutch Airlines, a unit of Air France-KLM SA, employees had expressed frustration at the company’s policy of providing and supporting only one type of laptop, the Lenovo A30 (formerly IBM), and one smartphone, the Nokia 6021. Last November, Martien van Deth, a senior technology officer in the Amsterdam office, tried a new system: He gave 50 information-technology staffers an allowance of $203, covering two years, to buy cellphones for corporate use. Those who picked more expensive phones paid the extra. Those who chose cheaper phones kept the change. As long as the phone ran Microsoft Corp.’s Windows Mobile version 5 or 6 operating system, KLM guaranteed access to corporate email. The catch: Users had to deal with technical problems themselves and replace phones that broke.

Not only did the program cost less than the $231 the company paid (p. A9) for phones and support over the same period, it was a hit with employees — some of whom bought phones with fancy ringtones and video players. Now "no one can complain that their corporate phone doesn’t have a camera," says Mr. van Deth, who plans to offer a tech allowance to KLM’s entire 1,000-person IT department later this summer, and wants to take the program companywide. He’s also about to start a tech-allowance program for laptops.

For-Sale-By-Owner Web Site Beats Real Estate Agents

 

Source of graphic:  online version of the NYT article cited below.

 

(p. A1)  It sounds like the setup for a dull economist’s joke. Who gets the better deal: the cautious economist who sells his house through a real estate agent, or his risk-taking colleague who finds a buyer on his own?

But the question — debated by two Northwestern University economists who chose different methods to sell their homes — and the research it helped prompt are serious. And the answer will be of interest to anyone who has paused to consider whether paying a real estate agent’s commission, typically 5 to 6 percent of the sale price, is worth it.

The conclusion, in a study to be released today based on home-sales data from 1998 to 2004 in Madison, Wis., is that people in that city who sold their homes through real estate agents typically did not get a higher sale price than people who sold their homes themselves. When the agent’s commission is factored in, the for-sale-by-owner people came out ahead financially.

London Mayor: Congestion-Pricing Works

 

In 2003, London put in place a £5 (about $9) a day congestion charge for all cars that entered the center city (the charge is now £8). This led to an immediate drop of 70,000 cars a day in the affected zone. Traffic congestion fell by almost 20 percent. Emissions of the greenhouse gas carbon dioxide were cut by more than 15 percent.

The negative side effects predicted by opponents never materialized. The retail sector in the zone has seen increases in sales that have significantly exceeded the national average. London’s theater district, which largely falls within the zone, has been enjoying record audiences. People are still flocking to London — they’re simply doing so in more efficient and less polluting ways.

. . .

Is London’s success a guarantee that congestion charging will work in New York? Of course not. But it is an indicator that properly executed congestion pricing works, and works well. Singapore and Stockholm already operate such programs and other cities are examining them. Given the success of congestion charging in London, this is not surprising.
