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

GoodHumorIceCreamTruck.jpg “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

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

CandyIndustryGraphic.gif 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

NewYorkLoftBuilding.jpg “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.

Why Most Economists Oppose the Gas Tax Holiday

(p. A31) Most economists oppose the Clinton-McCain gas tax holiday because they can’t see how consumers will benefit. In fact, “most” is an understatement; when challenged to name one economist willing to back her plan, Mrs. Clinton’s response was to disparage the whole profession.
Why are economists so opposed? In the short run, the supply of gasoline is basically fixed; it takes a while to build a new refinery. The demand for gasoline, in contrast, is more responsive to price; we’re already seeing greater use of public transportation and brisk sales of fuel-efficient cars. When you combine fixed supply with flexible demand, it’s suppliers, not demanders, who pocket the tax cut. That’s Econ 101.
. . .
When the public rejects the mundane explanations for high gas prices — big boring facts like rapid Asian growth — politicians aren’t going to correct them. The best we can expect is for Washington to try to channel the public’s misconceptions in relatively harmless directions. We could do a lot worse than the gas tax holiday; in fact, we usually do.

For Happiness, “Income Does Matter”

SatisfactionPerCapitaGDPgraph.jpg Source of graph: online version of the NYT article quoted and cited below.

(p. C7) . . . , Betsey Stevenson and Justin Wolfers argue that money indeed tends to bring happiness, even if it doesn’t guarantee it. They point out that in the 34 years since Mr. Easterlin published his paper, an explosion of public opinion surveys has allowed for a better look at the question. “The central message,” Ms. Stevenson said, “is that income does matter.”
To see what they mean, take a look at the map that accompanies this column. It’s based on Gallup polls done around the world, and it clearly shows that life satisfaction is highest in the richest countries. The residents of these countries seem to understand that they have it pretty good, whether or not they own an iPod Touch.
If anything, Ms. Stevenson and Mr. Wolfers say, absolute income seems to matter more than relative income. In the United States, about 90 percent of people in households making at least $250,000 a year called themselves “very happy” in a recent Gallup Poll. In households with income below $30,000, only 42 percent of people gave that answer. But the international polling data suggests that the under-$30,000 crowd might not be happier if they lived in a poorer country.
. . .
Economic growth, by itself, certainly isn’t enough to guarantee people’s well-being — which is Mr. Easterlin’s great contribution to economics. In this country, for instance, some big health care problems, like poor basic treatment of heart disease, don’t stem from a lack of sufficient resources. Recent research has also found that some of the things that make people happiest — short commutes, time spent with friends — have little to do with higher incomes.
But it would be a mistake to take this argument too far. The fact remains that economic growth doesn’t just make countries richer in superficially materialistic ways.
Economic growth can also pay for investments in scientific research that lead to longer, healthier lives. It can allow trips to see relatives not seen in years or places never visited. When you’re richer, you can decide to work less — and spend more time with your friends.
Affluence is a pretty good deal. Judging from that map, the people of the world seem to agree. At a time when the American economy seems to have fallen into recession and most families’ incomes have been stagnant for almost a decade, it’s good to be reminded of why we should care.

Franklin Roosevelt Exposed in The Forgotten Man

ForgottenManBK.jpg

Source of book image: http://blog.syracuse.com/shelflife/forgotten.jpg

Amity Shlaes’s new history of the Great Depression is at once depressing and encouraging. It is depressing in showing how vulnerable human progress is to the threat from a dishonest, slick orator, who has not a clue about how the economy works. It is encouraging in that it shows so clearly that the length and depth of the Great Depression was due to easily avoidable mistakes in policy, rather than due to some fundamental flaw in capitalism, as has occasionally been claimed.
Although the book does not shy away from pointing out the flaws of Coolidge, Hoover and Willke, it mainly shows how F.D.R.’s routine whimsical policy reversals and double-dealings, alienated not only his original opponents, but many of his early friends and allies.
The New Deal policies to seize business profits, reduced business incentives to take risks: if the risks turned out badly, the business would lose the investment, while if the risks turned out well, the profits would be taxed away by the federal government.
In addition, the sheer unpredictability of New Deal policies further led the prudent to delay investments, thereby further impeding recovery.
The book is well-written, and should be equally well-read.
