Caballero Worries about the Relevance of Mainstream Macro Modeling

In the past, I have found some of MIT economist Ricardo Caballero’s research useful because he takes Schumpeter’s process of creative destruction seriously.
In a recent paper, he joins a growing number of mainstream economists who worry that the recent and continuing economic crisis has implications for the methodology of economics:

In this paper I argue that the current core of macroeconomics–by which I mainly mean the so-called dynamic stochastic general equilibrium approach–has become so mesmerized with its own internal logic that it has begun to confuse the precision it has achieved about its own world with the precision that it has about the real one. This is dangerous for both methodological and policy reasons. On the methodology front, macroeconomic research has been in “fine-tuning” mode within the local-maximum of the dynamic stochastic general equilibrium world, when we should be in “broad-exploration” mode. We are too far from absolute truth to be so specialized and to make the kind of confident quantitative claims that often emerge from the core. On the policy front, this confused precision creates the illusion that a minor adjustment in the standard policy framework will prevent future crises, and by doing so it leaves us overly exposed to the new and unexpected.

France Lacked Good Patent Laws; Great French Inventors “Died Penniless”

(p. 367) If one secret to sustaining an inventive culture was making inventors into national heroes, it was a secret that didn’t translate well into French. Between 1740 and 1780, the French inclination to reward inventors not by enforcing a natural right but by the grant of pensions and prizes resulted in the award of nearly 7 million livres–approximately $600 million today–to inventors of largely forgot-(p. 268)ten devices, but Claude-François Jouffroy d’Abbans (inventor of one of the first working steamboats), Barthélemy Thimonnier (creator of the first sewing machine), and Airné Argand (a partner of Boulton and friend of Watt whose oil lamp became the world’s standard) all died penniless.

Occupational Licensing Adds Billions a Year to Cost of Services

PercentageWorkersLicensedGraph2011-02-27.jpg

(p. A1) . . . economists–and workers shut out of fields by educational requirements or difficult exams–say licensing mostly serves as a form of protectionism, allowing veterans of the trade to box out competitors who might undercut them on price or offer new services.

“Occupations prefer to be li-(p. A16)censed because they can restrict competition and obtain higher wages,” said Morris Kleiner, a labor professor at the University of Minnesota. “If you go to any statehouse, you’ll see a line of occupations out the door wanting to be licensed.”
While some states have long required licensing for workers who handle food or touch others–caterers and hair stylists, for example–economists say such regulation is spreading to more states for more industries. The most recent study, from 2008, found 23% of U.S. workers were required to obtain state licenses, up from just 5% in 1950, according to data from Mr. Kleiner. In the mid-1980s, about 800 professions were licensed in at least one state. Today, at least 1,100 are, according to the Council on Licensure, Enforcement and Regulation, a trade group for regulatory bodies. Among the professions licensed by one or more states: florists, interior designers, private detectives, hearing-aid fitters, conveyor-belt operators and retailers of frozen desserts.
. . .
Mr. Kleiner, of the University of Minnesota, looked at census data covering several occupations that are regulated in some states but not others, including librarians, nutritionists and respiratory therapists. He found that employment growth in those professions was about 20% greater, on average, in the unregulated states between 1990 and 2000.
Licensing can also drive up costs to consumers. Licensed workers earn, on average, 15% more than their unlicensed counterparts in other states–a premium that may be reflected in their prices, according to a study published by the National Bureau of Economic Research and conducted by Mr. Kleiner and Alan Krueger, an economist at Princeton University.
Mr. Kleiner estimates that across the U.S. economy, occupational licensing adds at least $116 billion a year to the cost of services, which amounts to about 1% of total consumer spending. In a look at dentistry, Mr. Kleiner found that the average price of dental services rose 11% when a state made it more difficult to get a dental license.

Property Rights Arise When Labor Creates Scarce Value

Marking snow-cleared parking spaces is a wonderful example of Demsetz’s theory of how property rights tend to emerge when the efficiency gains are large enough.
I remember when I was a graduate student in Chicago sometime in the mid-to-late 1970s, there were a couple of very snowy winters in which Chicagoans would similarly claim spaces from which they had cleared the snow.
I remember, but alas did not save, an article (probably in the Chicago Tribune) documenting how someone “stole” a marked space, and later returned to find that a garden hose had been used to cover their car in a considerable layer of ice.

(p. 8A) CHICAGO (AP) — A blizzard that dumped nearly 2 feet of snow on Chicago last week has revived a city tradition: Break out the patio furniture. Or, if none is available, suitcases, gar­bage cans, strollers, bar stools and milk crates work, too.

Chicagoans use all these items in a time-honored yet controver­sial system of preserving park­ing spots, a system known as “dibs.”
. . .
Actually, a city ordinance makes the practice illegal.
. . .
Even the city’s top police offi­cer sympathizes with those who do it.
“Think about it, you spend a couple hours clearing a spot, and somebody from another block takes it?” Superintendent Jody Weis said Friday.
. . .
“This is my spot because I worked hard to dig my car out,” said Max Rosario, 27, just be­fore he put his patio chair on the street. It joined 16 chairs, one slab of plywood, a plastic kids table, three bar stools and a TV dinner tray, among other things.

Kappos Says Private Company Would Have Run Patent Office Better

KapposDavidPatent2011-02-27.jpg “David Kappos of the Patent Office, with an Edison bulb.” Source of caption and photo: online version of the NYT article quoted and cited below.

(p. A1) “There is no company I know of that would have permitted its information technology to get into the state we’re in,” David J. Kappos, who 18 months ago became director of the Patent and Trademark Office and undersecretary of commerce for intellectual property, said in a recent interview. “If it had, the C.E.O. would have been fired, the board would have been thrown out, and you would have had shareholder lawsuits.”

Once patent applications are in the system, they sit — for years. The patent office’s pipeline is so clogged it takes two years for an inventor to get an initial ruling, and an additional year or more before a patent is finally issued.
The delays and inefficiencies are more than a nuisance for inventors. Patentable ideas are the basis for many start-up companies and small businesses. Venture capitalists often require start-ups to have a patent before offering financing. That means that patent delays cost jobs, slow the economy and threaten the ability of American companies to compete with foreign businesses.

Patent Importance Survives the Results of Moser’s Worlds Fairs Data Analysis

(p. 264) Petra Moser, now a professor at MIT’s Sloan School of Management, spent four years examining more than 15,000 different inventions exhibited at nineteenth-century worlds fairs, and their equivalents, and discovered a fact that seems at first glance to discredit the idea that patent protection was essential for innovation: Nations without patent laws were in many cases just as inventive as those with them. Or even more inventive; some of the nations best represented at those industrial fairs actively discouraged the patenting of inventions.

The reason seems to be that whether or not they enforced a patent law, smaller nations or domains, such as the Netherlands and Switzerland, were vulnerable to the theft of their innovations by competitors in larger nations. The bargain of patent protection runs two ways: The state, in return for making an idea public, offers legal recourse to its creator should someone within the state steal the idea. Since making one’s invention public in a nation with patent protection offered protection against theft only up to its own borders, only a large nation offered a large enough market to make the deal a good one, and (in Moser’s words) the small nations “would have been silly to patent [their] innovations.”
This logic inhibited investment in entire categories of innovation. Those nations that relied on secrecy rather than patent tended to specialize in the sort of inventions that cannot be easily reverse–engineered, such as chemicals or dyes.

Paul Romer Looking to Found a “Charter City”

Romer’s idea of setting up a Charter City sounds like a more advanced version of a free trade zone. It might work if you could find a well-governed nation to serve as guarantor of the city’s charter. That’s a big “if.”
Still, it’s a more intriguing idea for advancing economic development than most of the default policies (like sending foreign aid to be stolen by corrupt dictators).

(p. A2) For the past couple of years, economist Paul Romer has been hopscotching the globe looking for a country desperate enough to try his audacious notion: Start a new “charter city,” an enclave free of old laws and practices, as William Penn did in Pennsylvania. (Think “charter school,” a school free of union contracts and school bureaucracy.)

. . .
About a decade ago, he walked away from academia, started an online teaching company, sold it and then turned to his next big idea: To create jobs to lift millions out of poverty, take an uninhabited 1,000 square-kilometer tract (386 square miles), about the size of Hong Kong, preferably government-owned. Write a charter: the all-important rules. Allow anyone to move in or out. Invite foreign investors to build infrastructure for profit. And sign a treaty with a well-governed country, say Norway or Canada, to serve as “guarantor” to assure investors and residents that the charter will be respected, much as the British once did for Hong Kong, and–. . . .

Chinese Encyclopedia Was Burned to Protect Monopolies Granted by Emperor

(p. 262) As with Tudor England, government monopoly of patronage meant control. Virtually all copies of the seventeenth–century Chinese encyclopedia, the T’ien Kung K’ai-wu or Exploitation of the Works of Nature, which included illustrations of everything from hydraulics to metallurgy, were destroyed because, according to Joseph Needham, much of the material touched on industries that had been granted monopoly status by the Qing emperors: “The absence of political competition did not mean that technological progress could not take place, but it did mean that one decision-(p. 263)maker [i.e. the Emperor] could deal it a mortal blow.” It is therefore no surprise that a high percentage of both the inventions and inventors we associate with China from the time of the Han Dynasty to the Qings were government sponsored and employed.

Another liability of a strong central government is that it is, well, strong. Europe’s fragmented system of sovereign states made it possible for innovative minds such as Paracelsus, Leibniz. Rousseau, and Voltaire to “shop” for more congenial places whenever they skated too close to heretical or otherwise challenging notions; in China, one had to travel a thousand miles to a place where the empire’s writ ran not.

Did Bell, or Gray, Invent the Telephone?

TheTelephoneGambitBK2011-02-05.jpg

Source of book image: http://www.xconomy.com/wordpress/wp-content/images/2008/01/telephone-gambit.jpg

A great and important debate is occurring about the desirability of the patent system. Should it be abolished, or reformed? If The Telephone Gambit book is right, one of the spectacular failures of the system is in the awarding of a patent to Bell for the telephone.
That’s a big “if”: some of the reviewers on Amazon give reasons for doubting Shulman’s story.
I hope to have time to look into this further.

(p. D10) It was a brilliant concept. But was it Bell’s? What had happened during his trip to Washington that allowed Bell to abandon the blind alleys he had been exploring and to suddenly, not incrementally, find the technological solution?

The answer to that question is a tale involving high-powered Washington lawyers, political influence, a patent clerk with a booze problem, and improper access to Elisha Gray’s patent filing, where Bell found the secret to making the telephone work. Mr. Shulman lays out the evidence — documentary, scientific, chronological and psychological — piece by damning piece. He shows most impressively how Bell’s subsequent behavior and actions are entirely in keeping with those of a decent and honorable man having to live most of his long life (Bell died in 1924) with the knowledge that behind his fortune and his fame lay a single instance of brazen dishonesty, of intellectual theft.
“The Telephone Gambit” is solid history, and Seth Shulman makes it as much fun to read as an Agatha Christie whodunit by using the techniques of historiography the way Hercule Poirot used his “little gray cells.” That’s no small accomplishment.

“A Great Artisan Can Make a Family Prosperous; A Great Inventor Can Enrich an Entire Nation”

(p. 247) We feel real poignancy when we recall the bucolic life (even if we do so through the soft focus of nostalgia) of a country weaver happy in his work skills and content with his life. But those skills, like those of a medieval goldsmith or an ancient carpenter, could not, by their very nature, reproduce themselves outside the closed community of the initiates. One lesson of the Luddite rebellion specifically, and the Industrial Revolution generally, is that maintaining the prosperity of those closed communities–their pride in workmanship as well as their economic well-being—-can only be paid for by those outside the communities: by society at large. A great artisan can make a family prosperous; a great inventor can enrich an entire nation.

Bloggers See Bad Conditions for Entrepreneurs

conditions.gif

The chart above and the one below are from the recently-released results of the First Quarter 2011 influential blogger survey conducted by the Kauffman Foundation. (Tim Kane gave permission to put the charts on my blog.) artdiamondblog.com is one of the blogs included in the survey.

The results above show a perception that conditions are currently tough for entrepreneurs. The chart below displays one of the main reasons: the current economy is perceived as uncertain and fragile. There are many reasons for the uncertainty, but one of them is surely that the bloggers have doubts about the depth of support in government for the institutions and policies upon which entrepreneurship depends (like private property, restrained regulations, and low taxes).
