"Síndrome de Piketty"

Stuck in the Middle

A Bad Case of Piketty Syndrome

86 May 24, 2015 4:00 AM EDT

By Clive Crook

Let's agree, for the sake of argument, that severe inequality is a bad thing in its own right. Does it also act as a drag on the economy? Recent research suggests it does, and calls into question the standard justification for tolerating rising inequality -- namely, that it's the price a society must pay for economic growth and overall prosperity.
In an earlier post I discussed Arthur Okun's classic book on this subject, "Equality and Efficiency: The Big Tradeoff." I defended Okun's view that, as a practical matter, the trade-off is almost impossible to avoid, even though it's true that, in theory, opportunities abound to make society both fairer and more efficient. Last week a new study from the Organization for Economic Cooperation and Development brought fresh evidence to this debate.
The title of this third big OECD volume on inequality captures the main theme: "In It Together: Why Less Inequality Benefits All." It reports that income inequality measured at the country level (as opposed to globally) has been rising almost everywhere for years. It also finds that "income inequality tends to drag down GDP growth" -- a finding you can expect to see cited frequently. On the face of it, measures to reduce inequality will therefore boost growth. In other words, there's no trade-off, and Okun was wrong.
Yet, as the report goes on to explain, it isn't quite so simple.
The OECD states this main finding so that it sits well with the prevailing obsession over inequality (thus guaranteeing that the report will be noticed), yet does so in a way that invites both misunderstanding and, I believe, misdirected effort. I suspect a case of Piketty Syndrome.

Nova Loman pode triplicar rendimento de juízes

A proposta do Supremo Tribunal Federal para uma nova lei para a magistratura, cuja minuta foi encaminhada aos integrantes da corte no fim do ano do Judiciário (19/12) contém adicionais e benefícios financeiros que ultrapassam os pedidos por um aumento salarial.
Os ministros do tribunal têm o maior contracheque do funcionalismo público nacional e uma elevação de seus salários traz a reboque, automaticamente, impacto nas contas públicas de Estados e da União. Em vez de aumento do salário, a nova lei amplia os chamados penduricalhos.
Uma soma simples mostra que os benefícios e auxílios previstos no novo Estatuto da Magistratura podem triplicar os rendimentos dos juízes, levando os valores para o patamar de R$ 90 mil. O valor é alcançado quando calculados todos os benefícios, auxílios e verbas estipulados na minuta.
Enxugando esses números e criando alguns cenários absolutamente factíveis chega-se ao seguinte exemplo:

A Handful Of Bronze-Age Men Could Have Fathered Two Thirds Of Europeans

Daniel Zadik — The Conversation

1

Europe has surprisingly little genetic variety. Learning how and when the modern gene-pool came together has been a long journey. But thanks to new technological advances a picture is slowly coming together of repeated colonization by peoples from the east with more efficient lifestyles.

Top image: An 1899 painting by Viktor Vasnetsov imagining a kurgan burial rite. (wikimedia/cc)

In a new study, we have added a piece to the puzzle: the Y chromosomes of the majority of European men can be traced back to just three individuals living between 3,500 and 7,300 years ago. How their lineages came to dominate Europe makes for interesting speculation. One possibility could be that their DNA rode across Europe on a wave of new culture brought by nomadic people from the Steppe known as the Yamnaya.

Warren Buffett: Stop Blaming The Rich For Income Inequality. If You Really Want To Help, Do This

The world’s third-richest man weighed in on the national debate over rising levels of income disparity in the United States yesterday, saying that while the gaps between the country’s haves and have nots are definitely increasing, it is not the fault of those at the top. Nor will it be solved by traditional methods, like improving education or hiking the minimum wage. His solution: Increase access to the Earned Income Tax Credit.

O fracasso da política redistributiva americana

Losing Ground: American Social Policy, 1950-1980, 10th Anniversary Edition Paperback – January 1, 1994

by

Charles Murray (Author)

This classic book serves as a starting point for any serious discussion of welfare reform. Losing Ground argues that the ambitious social programs of the1960s and 1970s actually made matters worse for its supposed beneficiaries, the poor and minorities. Charles Murray startled readers by recommending that we abolish welfare reform, but his position launched a debate culminating in President Clinton’s proposal “to end welfare as we know it.”

Desigualdade e crescimento - relatório do OECD

In It Together: Why Less Inequality Benefits All

OECD
The gap between rich and poor keeps widening. Growth, if any, has disproportionally benefited higher income groups while lower income households have been left behind. This long-run increase in income inequality not only raises social and political concerns, but also economic ones. It tends to drag down GDP growth, due to the rising distance of the lower 40% from the rest of society. Lower income people have been prevented from realising their human capital potential, which is bad for the economy as a whole. This book highlights the key areas where inequalities are created and where new policies are required, including: the consequences of current consolidation policies; structural labour market changes with rising non-standard work and job polarization; persisting gender gaps; the challenge of high wealth concentration, and the role for redistribution policies.

One Of The Most Important Scientists In The World: “Most Cancer Research Is Largely A Fraud”

“Everyone should know that most cancer research is largely a fraud, and that the major cancer research organisations are derelict in their duties to the people who support them.” (source)

The above quote comes from Linus Pauling, Ph.D, and two time Nobel Prize winner in chemistry (1901-1994). He is considered one of the most important scientists in history. He is one of the founders of quantum chemistry and molecular biology, who was also a well known peace activist. He was invited to be in charge of the Chemistry division of the Manhattan Project, but refused. He has also done a lot of work on military applications, and has pretty much done and seen it all when it comes to the world of science. A quick Google search will suffice if you’d like to learn more about him.

This man has been around the block, and obviously knows a thing or two about this subject. And he’s not the only expert from around the world expressing similar beliefs and voicing his opinion.

Here is another great example of a hard hitting quote when it comes to scientific fraud and manipulation. It comes from Dr. Marcia Angell, a physician and long time Editor in Chief of the New England Medical Journal (NEMJ), which is considered to be one of the most prestigious peer-reviewed medical journals in the world. I apologize if you have seen it before in my articles, but it is quite the statement.

Editor In Chief Of World’s Best Known Medical Journal: Half Of All The Literature Is False

In the past few years more professionals have come forward to share a truth that, for many people, proves difficult to swallow. One such authority is Dr. Richard Horton, the current editor-in-chief of the Lancet – considered to be one of the most well respected peer-reviewed medical journals in the world.

Dr. Horton recently published a statement declaring that a lot of published research is in fact unreliable at best, if not completely false.

“The case against science is straightforward: much of the scientific literature, perhaps half, may simply be untrue. Afflicted by studies with small sample sizes, tiny effects, invalid exploratory analyses, and flagrant conflicts of interest, together with an obsession for pursuing fashionable trends of dubious importance, science has taken a turn towards darkness.” (source)

This is quite distrubing, given the fact that all of these studies (which are industry sponsored) are used to develop drugs/vaccines to supposedly help people, train medical staff, educate medical students and more.

The fascinating cultural reason why Westerners and East Asians have polar opposite understandings of truth

By Drake Baer .

(Kevin Frayer / Getty) Tourists in Beijing.
Starting the spring of my 23rd year, I spent 13 months straight in East Asia, teaching English and traveling through South Korea, Japan, and China. 
As a 6'3'' blonde guy, it was pretty obvious that I looked different than just about everybody else.
What was less obvious is that as a Westerner, I thought differently than my new East Asian friends. Contracts, agreements, appointments — the cultural differences were huge.
According to cultural philosophers, Westerners and East Asians have had contrasting views about the concept of truth and how it works for thousands of years — and it shows up in present-day psychology.
It all goes back to the cradles of two civilizations: ancient Greece and ancient China.
It comes down to two different "laws":

• The Greeks followed the "law of the excluded middle," which states that if two people are debating, then one of them must be exclusively right and the other exclusively wrong. 

• The Chinese followed the "doctrine of mean," which states that if two people are debating, then they're probably both partly right and partly wrong — the truth probably lies somewhere in the middle. 

These things have deep roots.
The doctrine of the mean dates back to Confucius, who lived some 2,500 years ago. It is "widely considered as the highest ideal in Confucianism," write scholars Li-Jun Ji, Albert Lee, and Tieyuan Guo in "The Oxford Handbook of Chinese Psychology."

"Accordingly, Chinese are encouraged to argue for both sides in a debate (i.e. both arguments are correct), or to assign equal responsibilities in a dispute (i.e. no party is at complete fault)," they write. "This presents an interesting contrast with the law of the excluded middle in Western philosophies, according to which one ought to eliminate ambiguity or inconsistency by selecting one and only one of the conflicting ideas. Unlike the Chinese tradition, it assumes no merit in the middle ground." 
The "law of the excluded middle" has a very fancy Latin name: principium tertii exclusi.
Aristotle wrote about it in his "Ethics" about 2,300 years ago.
"There cannot be an intermediate between contradictories," he wrote, "but of one subject we must either affirm or deny any one predicate."
Incredibly, those ancient takes on truth show up in present-day psychology experiments.

In a widely cited 1999 paper, psychologists Kaiping Peng and Richard E. Nisbett gave Chinese and American college students a range of scenarios describing conflicts between people and asked for advice about how to resolve them.

As Confucianism would suggest, the Chinese students were more likely to give "dialectical" responses, or seeing truth and fault in both parties. 

One prompt was a family conflict:

Mary, Phoebe, and Julie all have daugthers. Each mother has held a set of values which has guided her efforts to raise her daugther. Now the daugthers have grown up, and each of them is rejecting many of her mother's values. How did it happen and what should they do?

The responses were remarkably different:  

• 72% of Chinese students gave compromise-oriented responses, like "both the mothers and the daugthers have failed to understand each other" 

• 74% of Americans found fault on one side, with responses like "mothers have to recognize daugthers' rights to their own values." 

Just as the differences between Confucius and Aristotle would suggest, Easterners and Westerners had different approaches to conflict. 

But those approaches didn't fall from the sky. They came from culture. 

In his 2004 book "The Geography of Thought," Nisbett describes the evolution. 

Here's Nisbett on China:

Science’s Significant Stats Problem

Researchers’ rituals for assessing probability may mislead as much as they enlighten.

By Tom Siegfried Illustration by Sergio Membrillas August 22, 2013

In 2009, researchers working in Thailand made headlines with a small success in a trial of an HIV vaccine. It reduced the rate of infection by 31 percent, the scientists calculated. That may not sound impressive, but in the fight against HIV, it looked like an unprecedented success. The researchers published their results in the influential New England Journal of Medicine, reporting that the data had passed standard statistical tests: If the vaccine had actually been worthless, there was only a 1 in 25 chance that it would have appeared to have the beneficial effect seen in the study.

In medicine, as in most other realms of science, observing low-probability data like that in the HIV study is cause for celebration. Typically, scientists in fields like biology, psychology, and other social sciences rejoice when the chance of a fluke is less than 1 in 20. In some fields, however, such as particle physics, researchers are satisfied only with much lower probabilities, on the order of one chance in 3.5 million. But whatever the threshold, recording low-probability data—data unlikely to be seen if nothing is there to be discovered—is what entitles you to conclude that you’ve made a discovery. Observing low-probability events is at the heart of the scientific method for testing hypotheses.
Scientists use elaborate statistical significance tests to distinguish a fluke from real evidence. But the sad truth is that the standard methods for significance testing are often inadequate to the task. In the case of the HIV vaccine, for instance, further analysis showed the findings not to be as solid as the original statistics suggested. Chances were probably 20 percent or higher that the vaccine was not effective at all.

Fraude

This was the biggest political science study of last year. It was a complete fraud.

Updated by Dylan Matthews on May 20, 2015, 1:50 p.m. ET @dylanmatt dylan@vox.com

Last year, UCLA grad student Michael LaCour and Columbia political scientist Donald Green published a startling finding, based on a experiment they ran: going door to door to try to persuade voters to support same-sex marriage works, they found, and it works especially well when the canvasser delivering the message is gay. They even found spillover effects: people who lived with voters who talked to a gay canvasser grew more supportive of same-sex marriage, too.
This was a really exciting conclusion, for political scientists and laypeople alike. Past research has suggested that people's political views are tribal and largely impervious to rational persuasion. Dartmouth political scientist Brendan Nyhan and the University of Exeter's Jason Reifler have conducted multiple studies that show correcting people's incorrect views about, say, the presence of WMDs in Iraq can actually backfire and make them hold their wrong beliefs even more firmly. LaCour and Green's study stood in stark contrast to this literature, suggesting that rational persuasion is actually possible. "It seemed like they'd invented something new," Ira Glass said in a This American Life segment highlighting the study, "a new tool to use to change people's opinions." In my writeup on April 8 of last year, I concluded that "what LaCour and Green found here is kind of miraculous."

Ciência falsificada

Groundbreaking Study On Gay Marriage Views May Have Been Faked

A seemingly groundbreaking and widely publicized study reported in Science magazine this past December may be a fake.
The study appeared to show that openly gay activists in California had persuaded conservative voters to change their minds in a lasting way by engaging the voters in “heartfelt, reciprocal and vulnerable conversations” about being gay during door-to-door advocacy campaigns. It was co-authored by Michael J. LaCour, a Ph.D. candidate in political science at the University of California, Los Angeles, and Donald P. Green, a professor at Columbia University.
For the gay rights movement, this was good news. It suggested that the country’s shift on gay rights was, at least in part, the movement’s doing, and it provided a template for advocacy going forward. Gay rights advocates in Ireland reportedly based their strategy before a national vote on same-sex marriage this week on LaCour and Green’s results.

Desigualdade da renda

 One of them was Robert Shapiro, a longtime Democratic advisor, who urged me to look at a paper he had recently written about income growth over the last several presidencies. I did.

At first glance, that paper, which the Brookings Institution published a few months ago without much fanfare or a catchy headline, is just another of those dry papers that Washington’s smartest economists churn out every year and that almost no one else actually reads. On closer inspection, though, Shapiro’s study is a remarkable analysis that refutes much of what we think we know about economic stagnation and inequality.

It’s worth trying to understand the argument here, even if you found your freshman economics class as baffling as I did. Because Shapiro’s data might explain why our politics feels so disconnected from reality — and what next year’s presidential candidates on both sides are in danger of missing.

China’s grand plans to build a railway through the Amazon has sparked controversy

CHINA has plans for a megastructure that will drastically affect one of the world’s most biodiverse environments.

On a visit to South America this week, Chinese premier Li Keqiang unveiled plans for a proposed railway track that would span South America from coast to coast.
The 5,300km train line would run from Brazil’s Atlantic coast to Peru’s Pacific coast and would be responsible for the destruction of dense forest, swamps and either desert or mountains in Peru.
China believes the track can be validated because it would greatly reduce the cost of transport for a number of Brazil’s exports such as of soy and iron ore, but conservationists think the ends don’t justify the means.
Christian Poirier, spokesman for advocacy group Amazon Watch, said the project would be the cause of long-lasting environmental and social damage

Enrollment in the liberal arts continues to sink, while academia dithers 

David Clemens  

Harvard is not alone. Between 2006 and 2011, the number of history majors at Cornell dropped 49 percent and English majors dropped 37 percent. Yale lost 60 percent of its English majors between 1991 and 2012. At my college, we no longer have courses in poetry, the short story, or the novel.  Many valid reasons have been given for the national decline: impractical majors, classrooms ossified by multiculturalism and identity politics, and the proliferation of arcane theorizing that has replaced the reading of great literature. It seems that the liberal arts academy has lost touch with the past as well as the present.
