McCraw on Schumpeter

Source of book image: http://reader2.com/wasp1028

I am in the process of writing a full-length review of McCraw’s book for the annual Research in the History of Economic Thought and Methodology. Suffice it to say that McCraw’s book is very useful and very interesting, and gets a lot right that is important. Most notably, McCraw appreciates that Schumpeter’s central message is that innovation is what matters most about capitalism.

Economists’ Statement on McCain Economic Plan (that I Signed)

I agreed to have my name added to the “Economist’s Statement” below, which was released to the press on Mon., July 7th. My general view is that free markets encourage morality, free choice, efficiency, and innovation; and that John McCain is much more likely to adopt free market policies than is Barack Obama.

Economists’ Statement:
We enthusiastically support John McCain’s economic plan. It is a comprehensive, pro-growth, reform agenda. The reform focuses on the real economic problems Americans face today and will face in the future. And it builds on the core economic principles that have made America great.
His plan would control government spending by vetoing every bill with earmarks, implementing a constitutionally valid line-item veto, pausing non-military discretionary government spending programs for one year to stop their explosive growth and place accountability on federal government agencies.
His plan would keep taxes from rising, because higher tax rates are exactly the wrong policy to restore economic growth, especially at this time.
His plan would reduce tax rates by cutting the tax that corporations pay to 25 percent in line with other countries, by completely phasing out the alternative minimum tax, by increasing the exemption for dependents, by permitting the first-year expensing of new equipment and technology, and by making permanent a reformed tax credit for R&D.
His plan would also create a new and much simpler tax system and give Americans a free choice of whether to pay taxes under that simple system or the current complex and burdensome income tax.
His plan would open new markets for American goods and services and thereby create additional jobs for Americans by supporting good free trade agreements, such as the one with Colombia, and working with leaders around the world to avoid isolationism and protectionism. His plan would also reform education, retraining, and other assistance programs so they better help those displaced by trade and other changes in the economy. His plan addresses problems in the financial markets and housing markets by calling for increased transparency and accountability, by targeted assistance to deserving homeowners to refinance their mortgages, and by opposing so-called reform plans which would raise the costs of home-ownership in the future.
The above actions, as well as plans to address entitlement programs — especially Social Security, Medicare and other government health care programs — and his regulatory reforms — especially in the area of health care — constitute a broad and powerful economic agenda. Because of John McCain’s experience working with the American people in all walks of life, with members of Congress on both sides of the aisle, and with leaders around the world, we are optimistic that these plans will become a reality and will create jobs and restore confidence and strong economic growth.

Reducing the Cost of Hotels: Prefab Rooms from China

“The Travelodge chain in Britain is building two hotels from stackable metal containers imported from China. One of the hotels, in Uxbridge in West London, is shown under construction at right and in a rendering at left.” Source of the caption and photo: online version of the NYT article quoted and cited below.

(p. 23) TRAVELODGE, one of the largest budget hotel chains in Britain, is a company in a hurry.
. . .
Once the company finds a location, it turns to a construction partner with equally aggressive plans: Verbus Systems, a London-based company that builds rooms in metal containers in factories near Shenzhen, China, and delivers them ready to be stacked into buildings up to 16 stories tall.
Verbus Systems’ commercial director, Paul Rollett, said his company “can build a 300-room hotel anywhere on the planet in 20 weeks.”
. . .
When they arrive at Heathrow, the containers will be hoisted into place by crane. The containers, which are as large as 12 by 47 feet, will support one another just as they do when they are crossing the ocean by ship, Mr. Rollett said. No additional structure is necessary.
. . .
DON CARLSON, the editor and publisher of Automated Builder, a trade magazine based in Ventura, Calif., said that in hotels, “modular is definitely the wave of the future.” Modular buildings, he said, are stronger, and more soundproof, because stacking units — each a fully enclosed room — “gives you double walls, double floors, double everything.”
Mr. Rollett agreed, saying that with the steel shipping container approach, “You could have a party in your room, and people in the next room wouldn’t hear a thing.”
. . .
He is working with his British clients, which, he said, include a Travelodge competitor, Premier Inn, to make the best possible use of the assembly-line method. “We’re increasing the degree of modularity,” he said, noting that the latest units come with fully fitted bathrooms and “even the paint on the walls.”
The only thing they don’t have, he said, “is the girl to put a chocolate on your pillow.”

Price Ceilings Also Hurt Those Who Mow Lawns

“Arjun Murti at Goldman Sachs studied the 1970s’ oil spikes. One had drivers lined up at a gas station in San Jose, Calif., in 1974.” Source of caption and photo: online version of the NYT article cited below.

The best part of the article below was the photo above of a gas line caused by the government’s imposing price ceilings on the price of gas. I’ve seen other photos of gas lines, but this is the first one I remember with someone waiting to fill up a lawn mower.

Optimal Size of a Firm Depends on Trial and Error and Changing Circumstances

Rosenberg and Birdzell give an uncommon reason for economies of scale. This illustrated that the common list of reasons is not written in stone. As trial and error yields new ways of organizing business, the optimal size firm will shift back and forth.

(p. 157) The increase in both size and complexity of ironworks that followed throughout the nineteenth century was motivated by a desire to achieve economies in the use of fuel. As to size, within the practical limits of construction, large furnaces lose less heat by radiation than small furnaces and so are more fuel-efficient.

Competition in an Ice Cream Duopoly

“Jose Martinez parked his Good Humor truck Tuesday at an Upper West Side corner that is said to be Mister Softee territory.” Source of caption and photo: online version of the NYT article quoted and cited below.

(p. C13) On Tuesday afternoon, new battle lines were drawn on the Upper West Side at the corner of Columbus Avenue and 83rd Street, where Ceasar Ruiz, 50, the Mister Softee man, said he had been selling ice cream without any competition for more than eight years.
He said his routine was the same every season. He arrives at the corner by about 2:30 each afternoon, mostly to catch the students getting out of Public School 9 and the Anderson School, just a few yards from the corner. He stays for about an hour and a half, then moves to his next location, he said.
But Tuesday afternoon was different. When he arrived, there sat the freshly painted Good Humor truck and Mr. Martinez, decked out in a crisp uniform, ringing his bell.
“I sell Good Humor, too,” Mr. Ruiz said. “But his is more cheap. I sell bar for $2. He might sell for $1.50. Not good. Not good.”
Over the din of children clamoring for Dora the Explorer ice cream bars and Mega Missile Pops (red, white and blue rocket-shaped popsicles), Mr. Martinez rang his bell louder, openly competing for customers.
“I’m trying to make a dollar just like he is,” said Mr. Martinez, his voice rising loud enough for the other driver to hear. “He’s telling me I have to go. But he doesn’t own this spot.”
. . .
About five minutes before 4 o’clock, Mr. Ruiz leaned out of his Mister Softee truck, looking over at Mr. Martinez.
“Tomorrow, I’m going to beat him here,” he said. “I’ll be the first one here.”

Key to Government Revenue is Economic Growth, Not High Tax Rates

Source of graph: online version of the WSJ article quoted and cited below.

(p. A23) Kurt Hauser is a San Francisco investment economist who, 15 years ago, published fresh and eye-opening data about the federal tax system. His findings imply that there are draconian constraints on the ability of tax-rate increases to generate fresh revenues. I think his discovery deserves to be called Hauser’s Law, because it is as central to the economics of taxation as Boyle’s Law is to the physics of gases. Yet economists and policy makers are barely aware of it.
. . .
The data show that the tax yield has been independent of marginal tax rates over this period, but tax revenue is directly proportional to GDP. So if we want to increase tax revenue, we need to increase GDP.
. . .
What makes Hauser’s Law work? For supply-siders there is no mystery. As Mr. Hauser said: “Raising taxes encourages taxpayers to shift, hide and underreport income. . . . Higher taxes reduce the incentives to work, produce, invest and save, thereby dampening overall economic activity and job creation.”

Today (May 30, 2008) is the publication date of the second edition of The New Palgrave Dictionary of Economics, which includes my “Economics of Science” article. The article surveys the history and current status of research on the economics of science, and the relationship of the economics of science to the economics of technology.
For a much earlier, and much longer, take on some of the same issues, see “The Economics of Science.”

Prices of Education and Medical Care Increase Dramatically Over Decade

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

The most interesting part of a recent David Leonhardt column, was not what he wrote, but the graphs that were included with the article, especially the one at the top of this entry. Notice that the price of education and medical care have increased much more dramatically than other categories of consumer spending. (And remember how heavily government is involved in those two sectors, both directly through government run institutions, and indirectly through regulations and subsidies.)

Candy Competition

Source of graphic: online version of the WSJ article quoted and cited below.

In class, we discuss how consumers pay higher prices for candy and soft drinks because the U.S. government limits on how much foregin sugar we can import. Sometimes a student will claim that candy companies would not lower prices if the price of sugar declined. And sometimes that issue leads to a discussion of whether the candy industry is competitive.
The graphic above, and the quotation below, provide some relevant evidence.

(p. B1) The global confectionary industry has long lacked a dominant player. The top 10 manufacturers controlled just 47% of the $141 billion market as of 2006, the most recent available data. . . .
. . .
If the Wrigley acquisition is successful, Mars will become the world’s largest confectionary company with about 14.4% of the market, overtaking Cadbury’s 10.1%, based on 2006 figures, the latest available, from Euromonitor International.

New York Rent Control Limits Incentives to Build Apartments

“Tryn Collins, left, and Mary Hill share small quarters at a loft building in Brooklyn that was transformed from a factory.” Source of caption and photo: online version of the NYT article quoted and cited below.

New York City has had rent control in effect for decades. Economists predict that one effect of rent control is that incentives are reduced to build and maintain apartments. As a result, those seeking living space, have fewer options. (For example, the WSJ a few years ago ran a front page article explaining how some enterprising New Yorkers were living in abandoned elevator shafts.)
The article quoted below, provides additional evidence.

(p. A1) One “room” is a cramped cubby that measures, in all, perhaps 25 square feet, just enough for a full-size mattress and whatever can be stashed beneath. The first-floor rooms, in the basement, are musty and windowless, like caves. The second-floor rooms have plywood walls but no doors, only cut-out windows that overlook a kitchen cluttered with day-old dishes, a chore wheel and the odd paintbrush.
One of the residents likens her home to a “giant treehouse.” Another says it is like “living in a public bathroom.”
“Where the stalls are just superficial sight lines that block the other person, but you can hear everything they do,” said Robyn Frank, a 23-year-old artist. She had just moved in to the McKibbin lofts in East Williamsburg, Brooklyn, and sometimes they literally become bathrooms. They are known for their giant, raucous parties; revelers occasionally urinate in the halls.
This is life in what some refer to as the McKibbin “dorms,” a landing pad for hundreds of postcollegiate creative types yearning to make it as artists, and live like them too, in today’s New York.
Newcomers marvel that such a place exists: two sprawling, almost identical five-story former factories filled with mostly white hip young things, smack in the middle of a neighborhood that has little in common with Williamsburg proper, its cocktail-mixing neighbor to the west.
Perhaps 300 people live in each building, which face each other and sit, respectively, at 248 and 255 McKibbin Street. Between one and eight people live in each loft. Few were born before the mid-1980s. Rents can range from $375 for one person to roughly $800 for a space.
