Online Employers Treat Workers More Honestly and Fairly than In-person Employers

(p. 233) John J. Horton surveys “The Condition of the Turking Class: Are Online Employers Fair and Honest?” Amazon Mechanical Turk is a “marketplace for work,” as explained at <https://www.mturk.com/mturk/welcome>. Employers post “Human Intelligence Tasks,” which can be tasks like writing keywords that accompany photos or writing bogus product reviews, and workers anywhere in the world can sign up to do them. Horton used Mechanical Turk to survey 200 respondents, who were paid 12 cents apiece for responding to a survey. Of the respondents, 111 were Americans, 58 from India, and the others from other countries. When asked what percentage of employers in their home country treat workers honestly and fairly, the average answer was 64 percent; in comparison, when asked what percentage of Mechanical Turk Requestors treated them (p. 234) fairly, the median answer was 69 percent.

Rajan Hired to Open India to Entrepreneurship

“Raghuram G. Rajan criticized Indian policy makers during a speech in April at the Indian School of Business. In August, the Indian government offered him a job.” Source of caption and photo: online version of the NYT article quoted and cited below.

(p. B3) NEW DELHI — In April, the economist Raghuram G. Rajan gave a speech to a group of graduating Indian students in which he criticized the country’s policy makers for “repeating failed experiment after failed experiment,” rather than learning from the experiences of other countries. A week later, he assailed the government again, this time in a speech attended by Prime Minister Manmohan Singh.

But instead of drawing a rebuke from India’s often thin-skinned leaders, he got a job offer. In August, Mr. Singh, who has frequently sought Mr. Rajan’s advice, called and asked him to take a leave from his job as a professor at the University of Chicago to return to India, where he was born, to help revive the country’s flagging economy. Within weeks, he was at work as the chief economic adviser in the Finance Ministry.
Analysts say the appointment of an outspoken academic like Mr. Rajan, along with the recent push by New Delhi to reduce energy subsidies and open up retailing, insurance and aviation to foreign investment, signal that India’s policy makers appear to be serious about tackling the nation’s economic problems.
. . .
Mr. Rajan said he would like to focus his efforts on three big themes: liberalizing India’s financial system; making it easier to do business, particularly for entrepreneurs and manufacturers; and fixing India’s dysfunctional food distribution system, which wastes a lot of food even as many of the country’s poor are malnourished.

Entrepreneurial Capitalism Offers the Best Chance “for a Life of Engagement and Personal Growth”

(p. 228) Edmund S. Phelps explores “Refounding Capitalism.” “One has to conclude that ‘generation of wealth’ is not special to capitalism. Corporatist economies are quite good at that. . . . A merit of a well-functioning capitalism (again: I do not mean free-market policy: low tax rates, etc.) is the economic freedoms it offers entrepreneurs, managers, employees and consumers–freedoms that socialist, corporatist and statist systems do not provide. . . . Ordinary people, if they are to find intellectual growth and an engaging life, have to look outside the home: these (p. 229) things can be found only at work, if anywhere. And for these rewards to be available for large numbers of people, the economy must be modern. And as a practical matter, that requires that it be based predominantly on a well-functioning capitalist system. Thanks to the grassroots, bottom-up processes of innovation, capitalism at its best can deliver–far more broadly than Soviet communism, eastern European socialism, and western European corporatism can–chances for the mental stimulation, problem-solving, exploration and discovery required for a life of engagement and personal growth.”

American Innovators Created Synergies and Interchangeable Parts

Source of book image: online version of the WSJ review quoted and cited below.

(p. A13) . . . the post-Civil War industrialization had an important and largely overlooked predecessor in the first decades of the 19th century, when, as Charles Morris writes in “The Dawn of Innovation,” “the American penchant for mechanized, large-scale production spread throughout industry, presaging the world’s first mass-consumption economy.” It is a story well worth telling, and Mr. Morris tells it well.
. . .
Whole industries sprang up as the country’s population boomed and spilled over into the Middle West. The rich agricultural lands there produced huge surpluses of grain and meat, especially pork. The city of Cincinnati–whose population grew to 160,000 in 1860, from 2,500 in 1810–became known as “Porkopolis” because of the number of hogs its slaughterhouses processed annually.
Mr. Morris does a particularly good job of explaining the crucial importance of synergy in economic development, how one development leads to another and to increased growth. The lard (or pig fat) from the slaughterhouses, he notes, served as the basis for the country’s first chemical industry. Lard had always been used for more than pie crust and frying. It was a principal ingredient in soap, which farm wives made themselves, a disagreeable and even dangerous task thanks to the lye used in the process.
But when lard processing was industrialized to make soap, it led to an array of byproducts such as glycerin, used in tanning and in pharmaceuticals. Stearine, another byproduct, made superior candles. Just in the decade from the mid-1840s to the mid-1850s, Cincinnati soap exports increased 20-fold, as did the export of other lard-based products. Procter & Gamble, founded in Cincinnati in 1837 by an Irish soap maker and an English candle maker who had married sisters, grew into a giant company as the fast-rising middle class sought gentility.
Mr. Morris goes into great detail on the development of interchangeable parts–the system of making the components of a manufactured product so nearly identical that they can be easily substituted and replaced.

Sweden Prospers from Low Taxes, No Stimulus and Fiscal Discipline

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

(p. A9) STOCKHOLM–Sweden’s economy, bolstered by solid exports and healthy consumer spending, is picking up considerable steam even as many of its European neighbors gasp for breath amid the struggle to contain the euro-zone debt crisis.

Sweden’s second-quarter economic output data, released Monday, significantly outpaced expectations, further solidifying the Northern European country’s reputation as a haven in a volatile period. The Swedish krona, which recently reached a 12-year peak against the euro, strengthened further after the report.
. . .
. . . , Sweden has built a reputation for fiscal discipline since it suffered a financial crisis in the early 1990s. Successive governments have since stuck to a target to post a surplus of 1% of GDP over any business cycle.
Lawmakers resisted the temptation to borrow to fuel growth during the boom of the early 2000s, which meant Sweden hit the global financial crisis of 2008 and 2009 with strong public finances. The government hasn’t needed to increase taxes in the way Spain has, or to cut spending as in the U.K.

Econometrician Leamer Argues for Methodological Pluralism

(p. 44) Ignorance is a formidable foe, and to have hope of even modest victories, we economists need to use every resource and every weapon we can muster, including thought experiments (theory), and the analysis of data from nonexperiments, accidental experiments, and designed experiments. We should be celebrating the small genuine victories of the economists who use their tools most effectively, and we should dial back our adoration of those who can carry the biggest and brightest and least-understood weapons. We would benefit from some serious humility, and from burning our “Mission Accomplished” banners. It’s never gonna happen.

“Highly Leveraged Economies, . . . , Seldom Survive”

Source of book image: http://si.wsj.net/public/resources/images/ED-AK313_book10_DV_20091008170122.jpg

(p. 762) Every once in a while, a work comes along whose key points ought to be part of the information set of every literate economist. Carmen M. Reinhart and Kenneth S. Rogoff’s This Time is Different: Eight Centuries of Financial Folly is such a work. It describes and analyzes a long international history of several types of financial crises.
. . .
The authors resist giving too much structural interpretation to their analysis. Most would agree with their conclusion that ” . . . highly leveraged economies, particularly those in which continual rollover of short-term debt is sustained only by confidence in relatively illiquid underlying assets, seldom survive” (p. 292).

Sclerotic Doctors Resist Change

(p. 177) Atherosclerosis, referring to a progressive and degenerative process of artery walls, is typically translated for a lay audience as “hardening of the arteries.” We’ve never needed a similar word to describe the medical community. It came with sclerosis built in. Of all the professions represented on the planet, perhaps none is more resistant to change than physicians. If there were ever a group defined by lacking plasticity, it would first apply to doctors.
(p. 178) The inherent “hardness” of physicians and the medical community suggests they will have a difficult time adapting to the digital world. Before the emergence of the Internet, physicians were high priests, holding all the knowledge and expertise, not to be challenged or questioned by the lowly consumer patient. “Doctor knows best” was the pervasive sentiment, shared by patients and especially physicians.

Econometric “Priests” Sell Their New “Gimmicks” as the “Latest Euphoria Drug”

The American Economic Association’s Journal of Economic Perspectives published a symposium focused on the thought-provoking views of the distinguished econometrician Edward Leamer.
I quote below some of Leamer’s comments in his own contribution to the symposium.

(p. 31) We economists trudge relentlessly toward Asymptopia, where data are unlimited and estimates are consistent, where the laws of large numbers apply perfectly and where the full intricacies of the economy are completely revealed. But it’s a frustrating journey, since, no matter how far we travel, Asymptopia remains infinitely far
away. Worst of all, when we feel pumped up with our progress, a tectonic shift can occur, like the Panic of 2008, making it seem as though our long journey has left us disappointingly close to the State of Complete Ignorance whence we began.

The pointlessness of much of our daily activity makes us receptive when the Priests of our tribe ring the bells and announce a shortened path to Asymptopia. (Remember the Cowles Foundation offering asymptotic properties of simultaneous equations estimates and structural parameters?) We may listen, but we don’t hear, when the Priests warn that the new direction is only for those with Faith, those with complete belief in the Assumptions of the Path. It often takes years down the Path, but sooner or later, someone articulates the concerns that gnaw away in each of (p. 32) us and asks if the Assumptions are valid. (T. C. Liu (1960) and Christopher Sims (1980) were the ones who proclaimed that the Cowles Emperor had no clothes.) Small seeds of doubt in each of us inevitably turn to despair and we abandon that direction and seek another.
Two of the latest products-to-end-all-suffering are nonparametric estimation and consistent standard errors, which promise results without assumptions, as if we were already in Asymptopia where data are so plentiful that no assumptions are needed. But like procedures that rely explicitly on assumptions, these new methods work well in the circumstances in which explicit or hidden assumptions hold tolerably well and poorly otherwise. By disguising the assumptions on which nonparametric methods and consistent standard errors rely, the purveyors of these methods have made it impossible to have an intelligible conversation about the circumstances in which their gimmicks do not work well and ought not to be used. As for me, I prefer to carry parameters on my journey so I know where I am and where I am going, not travel stoned on the latest euphoria drug.
This is a story of Tantalus, grasping for knowledge that remains always beyond reach. In Greek mythology Tantalus was favored among all mortals by being asked to dine with the gods. But he misbehaved–some say by trying to take divine food back to the mortals, some say by inviting the gods to a dinner for which Tantalus boiled his son and served him as the main dish. Whatever the etiquette faux pas, Tantalus was punished by being immersed up to his neck in water. When he bowed his head to drink, the water drained away, and when he stretched up to eat the fruit hanging above him, wind would blow it out of reach. It would be much healthier for all of us if we could accept our fate, recognize that perfect knowledge will be forever beyond our reach and find happiness with what we have. If we stopped grasping for the apple of Asymptopia, we would discover that our pool of Tantalus is full of small but enjoyable insights and wisdom.

“The Bulk of New Yorkers Do Not Have an Unlimited Appetite for Growing Their Own Kale”

“. . . , Ena K. McPherson holds the key to three different community gardens.” Source of caption and photo: online version of the NYT article quoted and cited below.

(p. D1) There is some evidence, . . . , that the bulk of New Yorkers do not have an unlimited appetite for growing their own kale. Official counts of New York gardens are fragmentary. But John Ameroso, the Johnny Appleseed of the New York community garden movement, suspects that the number of present-day gardens — around 800 — may be half what it was in the mid-1980s.

In his long career as an urban extension agent for Cornell University, Mr. Ameroso, 67, kept a log with ratings of all the plots he visited. “I remember that there were a lot of gardens that were not in use or minimally used,” he said. “Into the later ’80s, a lot of these disappeared or were abandoned. Or maybe there was one person working them. If nothing was developed on them, they just got overgrown.”
The truth, Ms. Stone said, is that at any giv-(p. D6)en time, perhaps 10 percent of the city’s current stock of almost 600 registered GreenThumb gardens is growing mostly weeds. “In East New York, I can tell you that there are basically many gardens that are barely functioning now.”
. . .
An honest census would reveal that many gardens (perhaps most) depend on just one or two tireless souls, said Ena K. McPherson, a Brooklyn garden organizer. She would know because she’s one of them.
Ms. McPherson holds the keys to three community gardens in Bedford-Stuyvesant. (Ms. Stone appreciatively refers to these blocks as “the Greater Ena McPherson Zone.”) And she serves on the operations committee for the nonprofit Brooklyn Queens Land Trust, which holds the deeds to 32 garden plots.
“In an ideal situation, we would have gardens with everyone in the community participating,” Ms. McPherson said. “But in fact, a few die-hard people end up carrying the flag.”
. . .
The original gardens followed the city’s vacant lots, which by 1978 numbered 32,000. Mr. Ameroso, though trained in agronomy, pitched them as an instrument for community renewal. “How did you take back your block?” he said. “Put in a community garden and stop that dumping.”
Ms. Stone, who laughingly (and earnestly) describes herself as a socialist, continues to embrace something of this mission. “All the people who are marginal in society — and I’m not using that as a judgmental term, it’s children, senior citizens, people on disability, the 47 percent — these people are the main power people in the garden,” she said.
These days, Mr. Ameroso espouses more of what he calls an “urban agriculture” model: a food garden with a dedicated farmers’ market or a C.S.A. These amenities make stakeholders out of neighbors who may not like dirt under their nails and rural farmers who drive in every weekend.
“The urban-agriculture ones are flourishing,” he said. “There’s a lot of excitement. They’re active eight days a week.” But “community gardens, as such, where people come in to take care of their own boxes — those are not flourishing.”
It’s almost a cliché to point out that this new green model seems to have attracted tillers with a different skin tone. “Back then,” Mr. Ameroso said of his earlier career, “when we worked in Bronx or Bed-Stuy, it was mostly communities of color. Now when we talk about the urban agriculture stuff, it’s white people in their 30s.”
What explains this demographic shift?
“I have no idea,” he said. “I’m still baffled by it, and I’m involved in it!”

Organic Farming Too Unproductive to End African Starvation

(p. 6) There is no shortage of writing — often from a locavore point of view — in support of more organic methods of farming, for both developed and developing countries. These opinions recognize that current farming methods bring serious environmental problems involving water supplies, fertilizer runoff and energy use. Yet organic farming typically involves smaller yields — 5 to 34 percent lower, as estimated in a recent study in the journal Nature, depending on the crop and the context. For all the virtues of organic approaches, it’s hard to see how global food problems can be solved by starting with a cut in yields. Claims in this area are often based on wishful thinking rather than a hard-nosed sense of what’s practical.
