Build a house in 24 hours
Randall Parker cites the following link:
Degussa AG, one of the world’s largest manufacturers and suppliers of construction materials, will collaborate in the development of a USC computer-controlled system designed to automatically “print out” full-size houses in hours.
Funded by a grant from the National Science Foundation, Behrokh Khoshnevis of the USC Viterbi School of Engineering’s Information Sciences Institute has been developing his automated house-building process, called “Contour Crafting,” for more than a year.
Khoshnevis believes his system will be able to construct a full-size, 2,000- square-foot house with utilities embedded in 24 hours. He now has a working machine that can build full-scale walls and is hoping to actually construct his first house in early 2005.
Contour Crafting uses crane- or gantry-mounted nozzles, from which building material – concrete, in the prototype now operating in his laboratory – comes out at a constant rate.
Moveable trowels surrounding the nozzle mold the concrete into the desired shape, as the nozzle moves over the work.
Parker adds:
Robots and other automated equipment have increased factory automation so much that factories are a dwinding source of all jobs. The next big target for automation has been and continues to be office work. Office automation is being addressed with the development of huge amounts of software and information systems.
What never seem to get as much attention is how to automate all the other places where people work aside from the office and the factory. Construction automation is an obvious big target. One approach is to do prefabrication of walls and other building pieces in highly automated factories. Then the prefabricated parts can be shipped to the construction site. But automated methods to doing construction at a site have advantages because they avoid the difficulty of shipping large walls, floors, and ceilings to a site. Also, automated site construction techniques allow more flexibility in site design.
My take: In economics language, this is called “g>r”, which refers to the growth rate of an economy exceeding its rate of interest. If we’re going to make it through our forthcoming fiscal crises, it will be through innovations such as these.
Is it a Vermeer or not?
You judge. Here are some scholarly takes, pro and con, along with more photos. It doesn’t look right to me, but many art experts now say yes. About three million pounds is at stake, according to The Telegraph. Since there are only about 35 other Vermeers in existence, and the last one was sold eighty years ago, I suspect it will go for more, no matter what the doubts.
My take: Researchers spent about ten years studying the picture. If it takes so long to tell the difference, spend your money elsewhere.

The French can compete
When the barricades that France’s protectionist auctioneers had erected to prevent the reform of their art market were finally stormed in late 2001, it seemed as though revolution was in the air. Many people believed that “les Anglo-Saxons”, as the French refer to Sotheby’s and Christie’s, were about to sweep their smaller, local competitors aside.
The logic was simple. The 456 licensed French auctioneers (commissaires-priseurs), who had been legally protected against foreign competition since 1556, would be no match for the two international giants now that the latter were allowed to hold sales in France for the first time. However, the reality has proved very different and in less than two and a half years Paris has evolved into the world’s most unpredictable and fiercely competitive art market centre.
And how can the French possibly compete?
The local auctioneers have survived by using their contacts, particularly among lawyers who arrange estate sales, and in some cases by reorganising and bringing in outside investors, which the law reforming the market allowed them to do for the first time. ArtCurial is a new creation, an alliance of three well-known French auctioneers – Francis Briest, Hervé Poulain and Remy Le Fur – with the Dassault aviation and newspaper dynasty and the Monaco real estate millionaire and art collector Michel Pastor. Its main specialities are modern art and vintage cars, and last year it came in third behind Christie’s and Tajan [another French firm] with sales of £41.7 million.
My take: European culture isn’t dead, it is simply oversubsidized and overprotected. Here is the full story. Here is an article about how the French have an unjustified fear of being bought out by foreigners.
Note also that Coca-Cola has postponed and possibly shelved its plans to compete with the leading French mineral waters. The British version of the product, Fasani (a terrible name, no?), turned out to be purified tap water. It is now an open question whether the French release will ever see the light of day.
Addendum: Daniel Drezner points out that McDonald’s is more popular in France than elsewhere in Europe. I blame expensive French food, high labor costs through regulation, and bizarre opening hours (i.e., your favorite place is usually closed). But if you think that French haute cuisine has been harmed, you haven’t eaten in Helene Darroze, where last night I had one of the finest meals of my life.
New economics blogs
One is called The Idea Shop. Andrew David Chamberlain, the blogmeister, describes the focus as “economics made simple.” So far it looks promising. The other is a new blog on economics for undergraduates.
Does file-sharing hurt CD sales?
A new study by two researchers at Harvard Business School and the University of North Carolina, Chapel Hill, finds that sharing digital music files has no effect on CD sales. This is the first study that directly compares actual downloads of music files and store sales of CDs.
The authors, Associate Professor Felix Oberholzer-Gee of Harvard Business School in Boston and Professor Koleman Strumpf of the University of North Carolina, Chapel Hill, conclude that “File sharing had no effect on the sale of popular CDs in the second half of 2002. While downloads occurred on a vast scale during this period – 3 million simultaneous users shared 500 million files on the popular network FastTrack/KaZaA alone – most people who shared files appear to be individuals who would not have bought the albums that they downloaded,” say the authors…
Even in the professors’ most pessimistic statistical model, it takes 5,000 downloads to reduce the sales of an album by a single copy. If this worst-case scenario were true, file sharing would have reduced CD sales by 2 million copies in 2002. To provide a point of reference, CD sales actually declined by 139 million copies from 2000 to 2002.
Here is another interesting tidbit:
31 percent of all individuals who download music live in the United States. Other important countries are Germany with a 13 percent share of worldwide users, Italy with 11 percent, Japan with 8 percent and France with 7 percent. File sharers in the United States are particularly active. While they represent 31 percent of worldwide users, they download 36 percent of all files.
U.S. file sharers download files from all over the world. Only 45 percent of the files downloaded in the United States come from computers in the U.S. 16 percent of music files are downloaded from computers in Germany, 7 percent from Canada, 6 percent from Italy, 4 percent from the U.K. A legal strategy that focuses mostly on the United States is unlikely to change the supply of music files.
In other words, going after domestic uploaders, as the RCAA is doing, won’t cut off supply.
Here is one summary. Here is the original research.
My take: Yes I believe the result. Most downloaders are young or just sampling songs for kicks. But I doubt if this, legal developments aside, would be true five years from now. Over time I expect more people to forgo buying the CD, unless of course the law intervenes.
Addendum: Newmark’s Door offers some additional links. Larry Lessig argues for complementarity. Here is an article that copyright is too strict more generally, and yes The Grey Album is wonderful.
Twenty questions

Are video games art?
Some time ago I asked whether video and computer games would provide the next artistic explosion. I concluded: “I’m still waiting to see the payoff.”
The New York Times ($) has nominated one such game, www.worldofawe.net as an aesthetically worthy experience, click on the link if you are curious. The game combines elements of music, travelogue, diaries, narrative, and digitally constructed artwork. One of the artworks has been included in the recent Whitney Biennial.
My take: Judge for yourself, but for me it is an interesting novelty more than a sustaining attraction. That being said, I didn’t like Faulkner at first either.
Cuban art
Before leaving for Paris I had the chance to give a talk on Latin American art in Tucson. While preparing I spent some time browsing Google Images for fun. One of my favorite Cuban painters is the expressionist Tomas Sanchez, I like the lusciousness of how he paints forests.
Here is another Sanchez. Manuel Mendive has a more primitivist style, here is my favorite Mendive. If you would like something more avant-garde, try Jose Bedia.
Here is one place to buy some reasonably priced Cuban art.
And how about the economics in Cuba?
State-run galleries sell selected works to tourists and pay artists a percentage, but successful artists like Sandra Ramos and The Carpinteros (Dagoberto Rodriques and Marco Castillo) prefer to deal directly with collectors, inviting them into their homes and studios where they do business in dollars that allow them to support their entire families. The opening week of the biennial is a feeding frenzy of foreign buying with collectors arriving in tours organised by US museums or European travel agencies. (The US allows importation of Cuban art and educational materials.)
With such considerable interest in the biennial, the State has been quick to recognise the potential of the market: an art auction at the biennial raised more than $100,000 to benefit a children’s cancer hospital, with an anonymous collector from Monaco paying $11,000 for a drawing by Kcho, an artist whose signature motif is a simple boat that might be interpreted as an allusion to Cubans’ efforts to escape the island. Somehow Kcho has been co-opted as a quasi-official artist, painting backdrops for Castro speeches and occupying a huge government house.
The bottom line: Censorship or not, if you tax everything else heavily, a good deal of talent will go into the art market. Alex and I wrote about this in our paper An Economic Theory of Avant-Garde and Popular Art, or High and Low Culture (PDF).
Piece work
Violinists at a German orchestra are suing for a pay rise on the grounds that they play many more notes per concert than their musical colleagues – a litigation that the orchestra’s director yesterday called “absurd”.
The 16 violinists at the Beethoven Orchestra, in the former West German capital Bonn argue that they work more than their colleagues who play instruments including the flute, oboe and trombone.
The violinists also say that a collective bargaining agreement that gives bonuses to performers who play solos is unjust.
Here is the full story. Here is a useful site on the labor theory of value. How about paying composers by the number of notes as well?
Bastiat’s house is for sale
The Dufaur de Gavardie de Monclar family, who jointly own Bastiat’s property in Souprosse, inform us that they have reluctantly decided to put it up for sale, as no one member of the family is able to purchase it. It consists of a fine 17th century manor house, with early 20th century alterations, approached via a long tree-lined driveway, a barn and an outbuilding, all set in grounds of 28,000 m².
The main house has a surface area of 200m², on three levels, that is 600m² of living space. The barn, with a timber-frame roof of outstanding architectural interest, has a surface area of 400m² and consists of three levels. The outbuilding is a house on two levels, with a surface area of 100m².
The whole property is for sale for 426,900 euros.
Here is the link, thanks to the Mises blog for the pointer. Here is a short biography of Bastiat that also contains links to many of his works. Perhaps I will stop by the house to pay my respects.
The ten most successful kleptocrats?
Directly below you will find a list of the most influential businessmen in history. For purposes of contrast, Ben Muse refers us to a list of the ten biggest political kleptocrats, here goes:
1. Mohamed Suharto President of Indonesia from 1967-98: US$15 to 35 billion
2. Ferdinand Marcos President of the Philippines from 1972-86 US$5 to 10 billion
3. Mobutu Sese Seko President of Zaire from 1965-97 US$5 billion
4. Sani Abacha President of Nigeria from 1993-98 US$2 to 5 billion
5. Slobodan Milosevic President of Serbia/Yugoslavia from 1989-2000 US$1 billion
6. Jean-Claude Duvalier President of Haiti from 1971-86 US$300 to 800 million
7. Alberto Fujimori President of Peru from 1990-2000 US$600 million
8. Pavlo Lazarenko Prime Minister of Ukraine from 1996-97 US$114 to 200 million
9. Arnoldo Alemán President of Nicaragua from 1997-2002 US$100 million
10. Joseph Estrada President of the Philippines from 1998-2001 US$78 to 80 million
It depends, of course, on what you count as stolen. Arguably some Saudis should make the list, though they claim to own the oil legitimately. Of course relative to gdp, Haiti’s Duvalier is a clear number one.
Addendum: Here is a good article on how Suharto did it.
Who are the most influential businessmen in history?
Joel Mokyr offers his list:

A good list, but it fails to reflect just how much business has transformed our society. How about Zukor, Laemmle, Fox, or Cohn, some of the early founders of Hollywood? You could add the Medici, the unknown father of double-entry bookkeeping, or how about Gutenberg for that matter?
Here is the complete article. Thanks to Lynne Kiesling for the pointer.
My whereabouts
Tomorrow I will be back at UNESCO, attending another meeting on cultural diversity. Several countries, most notably France, would like UNESCO to have the power to overturn the free trade commitments made through the WTO and the EU for that matter. Did you know that Brussels has told France that it must allow books to be advertised on television, something previously forbidden?
France and others would like to cement the principle of the “cultural exception” through as many international organizations as possible, UNESCO included. Of course the exceptions would not stop at culture, nor would the rubric of culture remain modest. Along other lines, some of the African experts at the meeting have come out for “enforceable sanctions” against countries that do not do “everything possible” to protect their native and indigenous cultures. I think this means us. I wonder if all of these people also favored sanctions against Saddam Hussein’s Iraq. In addition to his better-known crimes, Saddam went to great efforts to destroy the culture of the so-called marsh Arabs, draining the marsh was only part of his nefarious agenda. In these meetings I am arguing for…well, if you don’t know…you haven’t been reading this blog for long enough.
The timing for this visit is less propitious than my last trip. Then the Parisians were talking up cultural diversity while banning headscarves in the schools. Now U.S. officials are squawking because the WTO is telling us we cannot ban on-line gambling. Here is Republican Congressman Bob Goodlatte, sounding like a Frenchman: “It’s appalling…It cannot be allowed to stand that another nation can impose its values on the U.S. and make it a trade issue.” The Bush administration is planning to appeal the ruling.
So I will be busy. My personal posts will continue, but at a lower level than usual. Alex and our excellent guest bloggers will be active, and I will be back in full force upon my return.
Why are gas prices so high?
Today gas prices hit another high, at least in nominal terms. Why? It suffices to turn the floor over to Lynne Kiesling. Here is a related post of hers as well.
