Climate Models Allow “the Modeler to Obtain Almost Any Desired Result”

Integrated assessment models (IAMs) are the commonly-used models that attempt to integrate climate science models with economic effect models. In the passage quoted below, “SCC” stands for “social cost of carbon.”

(p. 870) I have argued that IAMs are of little or no value for evaluating alternative climate change policies and estimating the SCC. On the contrary, an IAM-based analysis suggests a level of knowledge and precision that is nonexistent, and allows the modeler to obtain almost any desired result because key inputs can be chosen arbitrarily.

As I have explained, the physical mechanisms that determine climate sensitivity involve crucial feedback loops, and the parameter values that determine the strength of those feedback loops are largely unknown. When it comes to the impact of climate change, we know even less. IAM damage functions are completely made up, with no theoretical or empirical foundation. They simply reflect common beliefs (which might be wrong) regarding the impact of 2º C or 3º C of warming, and can tell us nothing about what might happen if the temperature increases by 5º C or more. And yet those damage functions are taken seriously when IAMs are used to analyze climate policy. Finally, IAMs tell us nothing about the likelihood and nature of catastrophic outcomes, but it is just such outcomes that matter most for climate change policy. Probably the best we can do at this point is come up with plausible estimates for probabilities and possible impacts of catastrophic outcomes. Doing otherwise is to delude ourselves.

HR Regulations and Fear of Lawsuits Keep Managers from Firing Workers Who Do Not Work

(p. 1B) The biggest problem in your workplace has a name. His name is Jeff. . . .
Jeff sits two cubicles down from us, or three, or four. His real name may be John, Juan or Joan. He gets to the widget factory late, he leaves early and always mucks up his part of any group project. He complains, loudly, about the smallest things, and when you bring doughnuts for your birthday he probably takes three and then talks with his mouth full, too.
. . .
(p. 2B) . . . , morale suffers greatly when most of a company’s employees perceive that their supervisor is failing to deal with their low-performing co-worker, month after month, year after year.
For this, Hoogeveen blames a corporate culture that is so concerned about HR regulations, and the often-imagined threat of litigation, that bosses often fail to take into account how the trouble employee affects the larger climate.
. . .
. . . if Jeff doesn’t improve, he needs to be fired. This is perhaps the worst part of a boss’s job, Hoogeveen thinks. His eyes mist as he recalls firing an employee whom he liked, but who was simply a bad fit at QLI.
It’s human nature to avoid this conflict, to maintain the status quo and let Jeff be, he says. That’s what can and does happen at most Omaha companies.
But it’s bad for the employees, and it’s bad for business.
“A lot of this stuff is incredibly easy to understand,” says Omaha’s workplace mechanic [Kim Hoogeveen]. “It’s incredibly difficult to live.”

Entrepreneur Gutenberg’s Press Creatively Destroyed the Jobs of Scribes

(p. 32) Poggio possessed . . . [a] gift that set him apart from virtually all the other book-hunting humanists. He was a superbly well-trained scribe, with exceptionally fine handwriting, great powers of concentration, and a high degree of accuracy. It is difficult for us, at this distance, to take in the significance of such qualities: our technologies for producing transcriptions, facsimiles, and copies have almost entirely erased what was once an important personal achievement. That importance began to decline, though not at all precipitously, even in Poggio’s own lifetime, for by the 1430s a German entrepreneur, Johann Gutenberg, began experimenting with a new invention, movable type, which would revolutionize the reproduction and transmission of texts. By the century’s end printers, especially the great Aldus in Venice, would print Latin texts in a typeface whose clarity and elegance remain unrivalled after five centuries. That typeface was based on the beautiful handwriting of Poggio and his humanist friends. What Poggio did by hand to produce a single copy would soon be done mechanically to produce hundreds.

Countries that Protect Jobs Stifle Economic Growth

(p. 240) In an “Interview” conducted by Jessie Romero, John Haltiwanger discusses changing patterns of job creation and destruction: “But now we’re seeing a decline in the entry rate and a pretty stark decline in the share of young businesses. . . . But it’s also important to recognize that the decline in the share of young firms has occurred because the impact of entry is not just at the point of entry, it’s also over the next five or 10 years. A wave of entrants come in, and some of them grow very rapidly, and some of them fail. That dynamic has slowed down. . . . If you look at young small businesses, or just young businesses period, the 90th percentile growth rate is incredibly high. Young businesses not only are volatile, but their growth rates also are tremendously skewed. It’s rare to have a young business take off, but those that do add lots of jobs and contribute a lot to productivity growth. We have found that startups together with high-growth firms, which are disproportionately young, account for roughly 70 percent of overall job creation in the United States. . . . “I think the evidence is overwhelming that countries have tried to stifle the [job] destruction process and this has caused problems. I’m hardly a fan of job destruction per se, but making it difficult for firms to contract, through restricting shutdowns, bankruptcies, layoffs, etc., can have adverse consequences. The reason is that there’s so much heterogeneity in productivity across businesses. So if you stifle that destruction margin, you’re going to keep lots of low-productivity businesses in existence, and that could lead to a sluggish economy. I just don’t think we have any choice in a modern market economy but to allow for that reallocation to go on. Of course, what you want is an environment where not only is there a lot of job destruction, but also a lot of job creation, so that when workers lose their jobs they either immediately transit to another job or their unemployment duration is low.” Econ Focus, Federal Reserve Bank of Richmond, Second Quarter 2013, pp. 30-34. http://www.richmondfed.org/publications/research/econ_focus/2013/q2/pdf/interview.pdf.

How Sega Came Out of Nowhere to Leapfrog Near-Monopolist Nintendo

Source of book image: http://images.eurogamer.net/2014/usgamer/original.jpg/EG11/resize/958x-1/format/jpg

(p. C10) “Console Wars” tells how Sega, an unremarkable Japanese manufacturer of games played in arcades, came out of nowhere to challenge Nintendo for dominance of the videogame world in the first half of the 1990s. Nintendo, which had revived the stagnant home videogame category a few years earlier, had something close to a monopoly in 1990 and behaved accordingly, dictating terms to game developers and treating retailers as peons. Sega, in Mr. Harris’s telling, was a disruptive force in a highly concentrated market, introducing more advanced gaming technology, toppling Nintendo from its perch and becoming the largest seller of home videogame hardware in the U.S. by late 1993.

Mr. Harris’s hero is a former Mattel executive named Tom Kalinske, who became president of Sega of America, then a small subsidiary, in 1990. Mr. Kalinske assembled a team of crack marketers who would not have gone near Sega but for his reputation and persuasiveness. Within a year and a half, according to Mr. Harris, Mr. Kalinske’s leadership, along with a new gaming system called Genesis and a marketing assist from a mascot named Sonic the Hedgehog, made Sega the U.S. market leader in videogames.
And then, after only three years at the top, Sega fell from its pedestal. Sega’s management in Japan, suffering mightily from not-invented-here syndrome, rejected Mr. Kalinske’s proposals to collaborate with Sony and Silicon Graphics on new gaming systems. Instead, over his objections, Sega pushed out its ill-conceived Saturn game console in 1995. While Saturn flopped, Sony struck gold with its PlayStation; Silicon Graphics sold its chip with amazing graphics capabilities to Nintendo; and the game, so to speak, was over.
. . .
The author admits he has taken liberties: “I have re-created the scenes in this book using the information uncovered from my interviews, facts gathered from supporting documents, and my best judgment as to what version most closely fits the historical record,” he writes. The result is more a 558-page screenplay than a credible work of nonfiction.

Conserving Whales by a Market in Whale Shares

(p. 218) Ben A. Minteer and Leah R. Gerber propose “Buying Whales to Save Them.” “Under this plan, quotas for hunting of whales would be traded in global markets. But again, and unlike most ‘catch share’ programs in fifisheries, the whale conservation market would not restrict participation in the market; both pro- and antiwhaling interests could own and trade quotas . . . . Conservation groups, for example, could choose to buy whale shares in order to protect populations that are currently threatened; they could also buy shares to protect populations that are not presently at risk but that conservationists fear might become threatened in the future.” “Despite the widely acknowledged failure of the IWC [International Whaling Commission] moratorium to curtail unsustainable whaling, the whale conservation market idea has proved to be wildly controversial within conservation and antiwhaling circles. . . . Many critics of the idea are also plainly not comfortable with the ethics of putting a price on such iconic species–that is, with using contingent market methods for what they believe should be a categorical ethical obligation to preserve whales. On the other hand . . . the vulnerable status of many whale populations and the failure of the traditional regulatory response to halt unsustainable harvests call for a more innovative and experimental approach to whale policy, including considering unconventional proposals, such as the whale conservation market.” Issues in Science and Technology, Spring 2013, http://www.issues.org/29.3/minteer.html.

Required Recycling Can Waste Resources

(p. 215) Cato Unbound offers four essays on “The Political Economy of Recycling.” In the lead essay, Michael Munger asks: “Recycling: Can It Be Wrong, When It (p. 216) Feels So Right?” “There are two general kinds of arguments in favor of recycling. The first is that ‘this stuff is too valuable to throw away!’ In almost all cases, this argument is false, and when it is correct recycling will be voluntary; very little state action is necessary. The second is that recycling is cheaper than landfilling the waste. This argument may well be correct, but it is difficult to judge because officials need keep landfill prices artificially low to discourage illegal dumping and burning. Empirically, recycling is almost always substantially more expensive than disposing in the landfill. Since we can’t use the price system, authorities resort to moralistic claims, trying to persuade people that recycling is just something that good citizens do. But if recycling is a moral imperative, and the goal is zero waste, not optimal waste, the result can be a net waste of the very resources that recycling was implemented to conserve.” There are sharp and lively comments from Edward Humes, Melissa Walsh Innes, and Stephen Landsberg. June 2013, at http://www.cato-unbound.org/issues/june-2013/political-economy-recycling.

Open Source Guru Admits to “Mismatched Incentives” and “Serious Trouble Down the Road”

“Eric S. Raymond said that the code-checking system had failed in the case of Heartbleed.” Source of caption and photo: online version of the NYT article quoted and cited below.

(p. B1) SAN FRANCISCO — The Heartbleed bug that made news last week drew attention to one of the least understood elements of the Internet: Much of the invisible backbone of websites from Google to Amazon to the Federal Bureau of Investigation was built by volunteer programmers in what is known as the open-source community.

Heartbleed originated in this community, in which these volunteers, connected over the Internet, work together to build free software, to maintain and improve it and to look for bugs. Ideally, they check one another’s work in a peer review system similar to that found in science, or at least on the nonprofit Wikipedia, where motivated volunteers regularly add new information and fix others’ mistakes.
This process, advocates say, ensures trustworthy computer code.
But since the Heartbleed flaw got through, causing fears — as yet unproved — of widespread damage, members of that world are questioning whether the system is working the way it should.
“This bug was introduced two years ago, and yet nobody took the time to notice it,” said Steven M. Bellovin, a computer science professor at Columbia University. “Everybody’s job is not anybody’s job.”
. . .
(p. B2) Unlike proprietary software, which is built and maintained by only a few employees, open-source code like OpenSSL can be vetted by programmers the world over, advocates say.
“Given enough eyeballs, all bugs are shallow” is how Eric S. Raymond, one of the elders of the open-source movement, put it in his 1997 book, “The Cathedral & the Bazaar,” a kind of manifesto for open-source philosophy.
In the case of Heartbleed, though, “there weren’t any eyeballs,” Mr. Raymond said in an interview this week.
. . .
The problem, Mr. Raymond and other open-source advocates say, boils down to mismatched incentives. Mr. Raymond said firms don’t maintain OpenSSL code because they don’t profit directly from it, even though it is integrated into their products, and governments don’t feel political pain when the code has problems.
With OpenSSL, by contrast, “for those that do work on this, there’s no financial support, no salaries, no health insurance,” Mr. Raymond said. “They either have to live like monks or work nights and weekends. That is a recipe for serious trouble down the road.”

Forecasts of Mass Unemployment from Robots Were Wrong

(p. 215) Frank Levy and Richard J. Murnane consider the interaction between workers and machinery in “Dancing with Robots: Human Skills for Computerized Work.” “On March 22, 1964, President Lyndon Johnson received a short, alarming memorandum from the Ad Hoc Committee on the Triple Revolution. The memo warned the president of threats to the nation beginning with the likelihood that computers would soon create mass unemployment: ‘A new era of production has begun. Its principles of organization are as different from those of the industrial era as those of the industrial era were different from the agricultural. The cybernation revolution has been brought about by the combination of the computer and the automated self-regulating machine. This results in a system of almost unlimited productive capacity which requires progressively less human labor. Cybernation is already reorganizing the economic and social system to meet its own needs.’ The memo was signed by luminaries including Nobel Prize winning chemist Linus Pauling, Scientific American publisher Gerard Piel, and economist Gunnar Myrdal (a future Nobel Prize winner). Nonetheless, its warning was only half right. There was no mass unemployment–since 1964 the economy has added 74 million jobs. But computers have changed the jobs that are available, the skills those jobs require, and the wages the jobs pay. For the foreseeable future, the challenge of “cybernation” is not mass unemployment but the need to educate many more young people for the jobs computers cannot do.” Third Way, 2013, http://content.thirdway.org /publications/714/Dancing-With-Robots.pdf.

They Begged for a Chance to Help Edison Create the Future

(p. 289) He, and anyone working for him, were perceived as standing at the very outer edge of the present, where it abuts the future. When a young John Lawson sought a position at Edison’s lab and wrote in 1879 that he was “willing to do anything, dirty work–become anything, almost a slave, only give me a chance,” he spoke with a fervency familiar to applicants knocking today on the door of the hot tech company du jour. In the age of the computer, different companies at different times–for example, Apple in the early 1980s, Microsoft in the early 1990s, Google in the first decade of the twenty-first century–inherited the temporary aura that once hovered over Edison’s Menlo Park laboratory, attracting young talents who applied in impossibly large numbers, all seeking a role in the creation of the zeitgeist (and, like John Ott, at the same time open to a chance to become wealthy). The lucky ones got inside (Lawson got a position and worked on electric light).

Raghuram Rajan: “Never in the Field of Economic Policy Has So Much Been Spent, with So Little Evidence, by So Few”

(p. 213) Raghuram Rajan delivered the Andrew Crockett Memorial Lecture at the Bank of International Settlements, titled “A Step in the Dark: Unconventional Monetary Policy after the Crisis.” “Two competing narratives of the sources of the crisis, and attendant remedies, are emerging. The first, and the better known diagnosis, is that demand has collapsed because of the high debt build up prior to the crisis. . . . But there is another narrative. And that is that the fundamental growth capacity in industrial countries has been shifting down for decades now, masked for a while by debt-fueled demand. More such demand, or asking for reckless spending from emerging markets, will not put us back on a sustainable path to growth. Instead, industrial democracies need to improve the environment for growth. The first narrative is the standard Keynesian one, modified for a debt crisis. It is the one (p. 214) most government officials and central bankers, as well as Wall Street economists, subscribe to, and needs little elaboration. The second narrative, in my view, offers a deeper and more persuasive view of the blight that afflicts our times.” Rajan argues that central banks took the right actions during the financial crisis, but that the wisdom of the ultra-low interest rate policies in the aftermath of the crisis are not yet clear. “Churchill could well have said on the subject of unconventional monetary policy, ‘Never in the field of economic policy has so much been spent, with so little evidence, by so few’. Unconventional monetary policy has truly been a step in the dark.” June 23, 2013, at http://www.bis.org/events/agm2013/sp130623.htm.
