The Gini coefficient is a measure of statistical dispersion developed by the Italian statistician Corrado Gini and published in his 1912 paper "Variability and Mutability". Worldwide, Gini coefficients for income range from approximately 0.23 (Sweden) to 0.70 (Namibia) although not every country has been assessed.

No matter how the Department of Statistics jiggle the numbers, Singapore's Gini coefficient (ranked second highest in 2009) is an ugly reminder of the widening income disparity. The orange line is based on lower numbers adjusted for "Government benefits and taxes" to pretty up a gruesome picture. If they are referring to housing grants or GST relief payouts credited to the CPF account, we know neither provides the hard cash to put food on the table. Or pocket money for the school kid to stave off hunger pangs during recess time. NTUC's welcome largess of a 5 percent discount on 500 essential items like rice, cooking oil and detergent confirms the pitiful plight of the poor is very real. Never mind if the temporal relief is only good for 3 months, after which the general election should be over, and a new round of price hikes will be slammed in.

Meanwhile the holdouts against a minimum wage salvation are still preaching the skill upgrade gospel. MP Liang Eng Hwa repeats the official mantra, "Rather than cash handouts, training and increasing their productivity may help them break out of the low wage cycle."

It is just logical that one cannot make the claim that action on climate change will influence future extreme events without first being able to claim that greenhouse gas emissions have a discernible influence on those extremes. This probably helps to explain why there is such a push to classify the attribution issue as settled. But this is just piling on one bad argument on top of another.

Even if you believe that attribution has been achieved, these are bad arguments for the simple fact that detecting the effects on the global climate system of emissions reductions would take many, many (many!) decades.  For instance, for an aggressive climate policy that would stabilize carbon dioxide at 450 ppm, detecting a change in average global temperatures would necessarily occur in the second half of this century.  Detection of changes in extreme events would take even longer.

To suggest that action on greenhouse gas emissions is a mechanism for modulating the impacts of extreme events remains a highly misleading argument.  There are better justifications for action on carbon dioxide that do not depend on contorting the state of the science.

Rosling has maintained a fact-based worldview – an understanding of how global health trends act as a signifier for economic development based on hard data. Today, he argues, countries and corporations alike need to adopt that same data-driven understanding of the world if they are to make sense of the changes we are experiencing in this new century, and the opportunities and challenges that lie ahead.

the world has changed so much, what people need isn’t more data but a new mindset. They need a new storage system that can handle this new information. But what I have found over the years is that the CEOs of the biggest companies are actually those that already have the most fact-based worldview, more so than in media, academia or politics. Those CEOs that haven’t grasped the reality of the world have already failed in business. If they don’t understand what is happening in terms of potential new markets in the Middle East, Africa and so on, they are out. So the bigger and more international the organisation, the more fact-based the CEO’s worldview is likely to be. The problem is that they are slow in getting their organisation to follow.

Companies as a whole are stuck in the rut of an old mindset. They think in outworn categories and follow habits and assumptions that are not, or only rarely, based on fact.

The Sex Life of the Screwworm -- a silly subject for federally funded research, no?Some members of Congress thought so: they singled out the project about 30 years ago as the nation’s top symbol of wasteful spending -- and later apologized when, upon further review, they realized the research was actually incredibly useful. Now, at a time when Congressional scrutiny of science spending (supposedly silly and otherwise) is rising, the other side of the debate is reviving the symbol of the screwworm to bring attention to its cause, through a method that seems too un-scientific to be true: a tabloid.

Using silliness to combat accusations of silliness, the Association of American Universities published its inaugural issue of "Scientific Enquirer," defending federal funding for research that may seem utterly irrelevant at first glance, but is actually productive.

The screwworms scored the cover story for the January 2011 issue. “Sex and the Screwworm,” the headline reads, “Your tax dollars go to study the sex life of a parasite, Congress wants to know why.” Directly below, slapped on like a bumper sticker and in commanding font: “Saves Country Billions!” It’s not what you’d expect to see from a prestigious group of research institutions better known for its formality (if not occasional stuffiness), but if attracting eyeballs is the goal, they just might be on to something. After all, who understands the art of getting attention better than tabloid publishers?

Peer to peer file sharing (P2P) has made media distribution free and has become the bane of media monopolies. P2P file sharing means digital files can be copied and distributed at no cost. CD's, DVD's, and other older forms of holding media are no longer necessary, nor is the cost involved in making them or distributing them along a traditional logistical supply chain. Disc burners, however, allow users the ability to create their own physical copies at a fraction of the cost of buying the media from the stores. Supply and demand is turned on its head as the more popular a certain file becomes via demand, the more of it that is available for sharing, and the easier it is to obtain. Supply and demand increase in tandem towards a lower "price" of obtaining the said file.Consumers demand more as price decreases. Producersnaturally want to produce more of something as priceincreases. Somewhere in between consumers and producers meet at the market price or "marketequilibrium."P2P technology eliminates material scarcity, thus the more afile is in demand, the more people end up downloading it, andthe easier it is for others to find it and download it. Considerthe implications this would have if technology made physicalobjects as easy to "share" as information is now.

In the end, it is not government regulations, legal contrivances, or licenses that govern information, but rather the free market mechanism commonly referred to as Adam Smith's self regulating "Invisible Hand of the Market." In other words, people selfishly seeking accurate information for their own benefit encourage producers to provide the best possible information to meet their demand. While this is not possible in a monopoly, particularly the corporate media monopoly of the "left/right paradigm" of false choice, it is inevitable in the field of real competition that now exists online due to information technology.

Compounding the establishment's troubles are cheaper cameras and cheaper, more capable software for 3D graphics, editing, mixing, and other post production tasks, allowing for the creation of an alternative publishing, audio and video industry. "Underground" counter-corporate music and film has been around for a long time but through the combination of technology and the zealous corporate lawyers disenfranchising a whole new generation that now seeks an alternative, it is truly coming of age.

look no further than the Fukada Sports Park, which serves the 7,500 mostly older residents here with a baseball diamond, lighted tennis courts, a soccer field and a $35 million gymnasium with indoor pool and Olympic-size volleyball arena. The gym is just one of several big public works projects paid for with the hundreds of millions of dollars this community is receiving for acce

the aid has enriched rural communities that were rapidly losing jobs and people to the cities. With no substantial reserves of oil or coal, Japan relies on nuclear power for the energy needed to drive its economic machine. But critics contend that the largess has also made communities dependent on central government spending — and thus unwilling to rock the boat by pushing for robust safety measures.

Tsuneyoshi Adachi, a 63-year-old fisherman, joined the huge protests in the 1970s and 1980s against the plant’s No. 2 reactor. He said many fishermen were angry then because chlorine from the pumps of the plant’s No. 1 reactor, which began operating in 1974, was killing seaweed and fish in local fishing grounds. However, Mr. Adachi said, once compensation payments from the No. 2 reactor began to flow in, neighbors began to give him cold looks and then ignore him. By the time the No. 3 reactor was proposed in the early 1990s, no one, including Mr. Adachi, was willing to speak out against the plant. He said that there was the same peer pressure even after the accident at Fukushima, which scared many here because they live within a few miles of the Shimane plant. “Sure, we are all worried in our hearts about whether the same disaster could happen at the Shimane nuclear plant,” Mr. Adachi said. However, “the town knows it can no longer survive economically without the nuclear plant.”

What many of these sceptics – or deniers, if you must – do question is a) whether – and if so by how much – this warming is anthropogenic (ie human-caused) b) whether the warming constitutes a threat – or whether its benefits might in fact far outweigh its drawbacks c) whether this warming likely to continue or whether – as happened without human influence at the end of the Roman warm period and the Medieval warm period – it will be followed by a period of natural cooling d) whether the drastic policy measures (tax, regulation, “decarbonisation”, the drive for renewables) being enacted to ‘combat climate change’ will not end up doing far more harm than good.

Though Dr Jones’s report argues that the BBC should from henceforward give less space to sceptics, it’s difficult to imagine quite how it could possibly do so. About the only occasion on which they have been given any air space has been on hatchet-jobs like the BBC’s feature-length assault on Lord Monckton, “Meet The Climate Sceptics”.

In the United States, nearly a half century of research, application of new technologies and development of new methods and policies has failed to translate into improved reading abilities for the nation’s children1.

the reasons why progress has been so uneven point to three simple rules for anticipating when more research and development (R&D) could help to yield rapid social progress. In a world of limited resources, the trick is distinguishing problems amenable to technological fixes from those that are not. Our rules provide guidance\ in making this distinction . . .

unlike vaccines, the textbooks and software used in education do not embody the essence of what needs to be done. That is, they don’t provide the basic ‘go’ of teaching and learning. That depends on the skills of teachers and on the attributes of classrooms and students. Most importantly, the effectiveness of a vaccine is largely independent of who gives or receives it, and of the setting in which it is given.

The reality is that a bold new energy and climate change policy would inevitably result in dislocations in certain industries and upset long-established ways of life in many regions; in addition, it would lead to higher prices for basic commodities such as gas, home heating oil, and food. In societies where there are strong social safety nets -- universal healthcare, universal preschool, strong support for new parents, significant investments in public transportation, and sustained support for higher education -- the changes wrought by a paradigm shift in energy will tend not to result in hugely destabilizing effects across whole towns and communities. In fact, with good planning and investments in critical infrastructure, strong environmental policies can result in overall improvements in the quality of life for nearly everyone. Throughout much of the developed world, citizens are willing to pay prices for gasoline that would lead to riots in American streets, because they know that the government revenue raised by high gas taxes is used for programs that directly benefit them. In other words, ten-dollar-a-gallon gas isn’t such a big deal when everyone has great healthcare, great public transportation, and free high-quality schooling.

Americans are so battered and anxious right now. Median wages are flat, unemployment is high, politics is paralyzed. Middle-class families are one health problem away from ruin, and when they fall, there's no net. That kind of insecurity, as much as anything, explains the American reticence to launch bold new social programs.

Michael Levi points to a fantastic piece by Nassim Taleb and Mark Blyth wherein they approach a similar subject from a seemingly contrary angle, arguing that government efforts to suppress social and economic volatility can backfire. Without the experience of adjusting to small shocks as they come, we won't be prepared when the big shocks arrive:

THINK income inequality growth is primarily an American phenomenon?  Think again:American society is more unequal than those in most other OECD countries, and growth in inequality there has been relatively large. But with very few exceptions, the rich have done better over the past 30 years, even in highly egalitarian places like Scandinavia.

Over the past decades, OECD countries have undergone significant structural changes resulting from their closer integration into a global economy and rapid technological progress. These changes have brought higher rewards for high-skilled workers and thus affected the way earnings from work are distributed. The skills gap in earnings reflects several factors. First, a rapid rise in trade and financial markets integration has generated a relative shift in labour demand in favour of high-skilled workers at the expense of low-skilled labour. Second, technical progress has shifted production technologies in both industries and services in favour of skilled labour...Finally, during the past two decades most OECD countries carried out regulatory reforms to strengthen competition in the markets for goods and services and associated reforms that aimed at making labour markets more adaptable. For instance, anti-competitive product-market regulations were reduced significantly in all countries. Employment protection legislation for workers with temporary contracts also became more lenient in many countries. Minimum wages, relative to average wages, have also declined in a number of countries since the 1980s. Wage-setting mechanisms have also changed; the share of union members among workers has fallen across most countries, although the coverage of collective bargaining has generally remained rather stable over time. In a number of countries, unemployment benefit replacement rates fell, and in an attempt to promote employment among low-skilled workers, taxes on labour for low-income workers were also reduced.

It's tempting to look at this list of regulatory changes and argue that it was these rule changes which facilitated growth in inequality. That may be true to some extent, but the unverisality of the reform experience makes me think it's at least as likely that underlying trends (like globalisation and technological change) made the prevailing rules unsustainable.

it is easy to forget that market forces, if allowed to play out, might eventually exert a stabilizing role. Simply put, the greater the premium for highly skilled workers, the greater the incentive to find ways to economize on employing their talents.

one of the main ways to uncover cheating is by using a computer program to detect whether a player’s moves consistently resemble the favored choices of various top computer programs.
