As of earlier this month, there were more than 2,819 CHAdeMO DC rapid chargers installed across the country, far more than the 1,532 installed in the whole of Europe or 854 found in the U.S.

That massive number of accessible, reliable charging stations combined with lower-power level 2 charging provision — both private and public — now means there are more dedicated charging stations in Japan than there are gas stations.

Far more in fact: over 40,000 says Nissan, versus the 34,000 gas stations currently trading in Japan.

Japan is blanketed with charging stations.

Relying on diversity measures computed at the apartment block level under conditions of exogenous allocation of public housing in France, this paper identifies the effects of ethnic diversity on social relationships and housing quality. Housing Survey data reveal that diversity induces social anomie. Through the channel of anomie, diversity accounts for the inability of residents to sanction others for vandalism and to act collectively to demand proper building maintenance. However, anomie also lowers opportunities for violent confrontations, which are not related to diversity.

A sentence from the conclusion explains that last bit more clearly: “…fractionalization has no effect on public safety, diversity being associated with social anomie within the housing blocks rather than violent confrontations among neighbors — helped as well by an increase in municipal policing in municipalities of high diversity.”

The paper also offers a useful but brief survey of what we know about ethnic diversity and social capital.  Here is an earlier ungated copy (pdf).

This new NBER paper by John Komlos is of real interest, and it documents the “average is over” idea of the dwindling of middle class fortunes:

We estimate growth rates of real incomes in the U.S. by quintiles using the Congressional Budget Office’s (CBO) post-tax, post-transfer data as basis for the period 1979-2011. We improve upon them by including only the present value of earnings that will accrue in retirement and excluding items included in the CBO income estimates such as “corporate taxes borne by labor” that do not increase either current purchasing power or utility. We estimate a high and a low growth rate using two price indexes, the CPI and the Personal Consumption Expenditure index. The major consistent findings include what in the colloquial is referred to as the “hollowing out” of the middle class. According to these estimates, the income of the middle class 2nd and 3rd quintiles increased at a rate of between 0.1% and 0.7% per annum, i.e., barely distinguishable from zero. Even that meager rate was achieved only through substantial transfer payments. In contrast, the income of the top 1% grew at an astronomical rate of between 3.4% and 3.9% per annum during the 32-year period, reaching an average annual value of $918,000, up from $281,000 in 1979 (in 2011 dollars). Hence, the post-tax, post-transfer income of the 1% relative to the 1st quintile increased from a factor of 21 in 1979 to a factor of 51 in 2011. However, income of no other group increased substantially relative to that of the lowest quintile. Oddly, the income of even those in the 96-99 percentiles increased only from a multiple of 8.1 to a multiple of 11.3. We next estimate growth in welfare assuming diminishing marginal utility of income. A logarithmic utility function yields a growth in welfare for the middle class of roughly 0.01% to 0.07% per annum, which is indistinguishable from zero. With interdependent utility functions only the welfare of the 5th quintile experienced meaningful growth while those of the first four quintiles tend to be either negligible or even negative.

Analysts who have concluded that inequality in life expectancy is increasing have generally focused on life expectancy at age 40 to 50. However, we show that among infants, children, and young adults, mortality has been falling more quickly in poorer areas with the result that inequality in mortality has fallen substantially over time. This is an important result given the growing literature showing that good health in childhood predicts better health in adulthood and suggests that today’s children are likely to face considerably less inequality in mortality as they age than current adults.

We also show that there have been stunning declines in mortality rates for African-Americans between 1990 and 2010, especially for black men.

This is often forgotten:

One traditional way of measuring nations’ power relative to each other is to compare their gross domestic product. By this measure, Russia gained economically on all of its competitors as well as on the world as a whole in 1999-2015.

And this:

The GINC measures national power as the geometric mean of the following ratios:

  • TPR = total population of country ratio;
  • UPR = urban population of country ratio;
  • ISR = steel production of country ratio;
  • ECR = primary energy consumption ratio;
  • MER = military expenditure ratio;
  • MPR = military personnel ratio.

The GINC shows Russia’s power rising by 6.53 per cent in 1999-2014, while the power of the US, UK, France, Germany and Italy declined 13.14 per cent, 24.42 per cent, 24.23 per cent, 29.92 per cent and 27.29 per cent respectively in 2014 compared with 1999.

For music, at least:

The simultaneous advent of streaming music and the vinyl renaissance has led to some very interesting recording industry statistics over the past few months. Last month, the RIAA reported that vinyl revenues outpaced sales from streaming services, despite actual streams vastly outnumbering physical vinyl sold. Now, Nielsen has released data revealing that, for the first time ever, old music (the “catalog,” defined as music more than 18 months old) outsold new releases in 2015.

It’s important to note that Nielsen’s numbers here don’t include streaming numbers, but that in itself is telling of current trends: an easy-to-draw hypothesis from these stats is that new music exists primarily in the streaming realm, rather than in album downloads or physical copies. And as 2016 has progressed and seen such things as Kanye’s The Life of Pablo shenanigans, exclusive streaming rights, like Rihanna and Beyoncé with Tidal and Drake with Apple Music, and the fact that the Beatles dominated Spotify in their first 100 days on the service, streaming music’s hold on the future seems to be growing tighter.

And note this:

Pink Floyd’s Dark Side of the Moon was the third-best-selling vinyl record of 2015.

I suspect you are not surprised to hear that Prince is dominating the Billboard 200 right now.

True or false? A new nuclear power station in the south-west of the UK will be the most expensive object on Earth. That’s the claim about the proposed plant at Hinkley Point in Somerset – but has anything else ever cost so much to build?

“Hinkley is set to be the most expensive object on Earth… best guesses say Hinkley could pass £24bn ($35bn),” said the environmental charity Greenpeace last month as it launched a petition against the project.

…Even if you stick with the expense of construction alone, though, the price is still high – the main contractor, EDF, puts it at £18bn ($26bn).

Here is the story, via Tim Harford.  Being good Austrians, let’s put cost of production aside and focus on potential market value.  Might there be an object which would auction for at least this much, if it were put on the market?  If so, which one?  The Mona Lisa?  A pyramid?  How about St. Peters?  Worth more or less than a nuclear power plant?  The Grand Mosque in Mecca?  The Great Wall of China?

Going back to cost of production, the article also mentions:

But these are all exceeded by the $54bn (£37bn) Gorgon liquefied natural gas plant built by Chevron in Australia.

And (not on earth):

The International Space Station. Price tag: 100bn euros (£77.6bn, or $110bn).

Trading volumes of the most-traded steel rebar contract in Shanghai hit a record 1.3bn tonnes today, or enough to build the Sydney Harbour Bridge 24,621 times.

If skyscrapers are the preferred metric, fret not: trades today were also equivalent to approximately 41,401 Burj Khalifas.

…One could construct around 178,082 Eiffel Towers with the above-mentioned volume of steel rebar traded today in Shanghai.

Here is the FT story.  Hat tip goes to the ever-excellent Christopher Balding.

From a new Pew Study:

In our latest national political survey, released in March, 59% of the public say immigrants strengthen the country, while 33% describe them as a burden. In 1994, opinions were nearly the reverse: 63% said immigrants were a burden and 31% said they strengthened the country.

You will note that they views of Republicans and Democrats diverge after 2006.  Millennials are especially favorably inclined.


It offers many interesting facts and angles (pdf here).  Here is one instructive paragraph of note:

Relative to other factors, rising prison admission rates have been the most important contributor to the increase in incarceration. Raphael and Stoll (2013b) decompose the growth in the prison population into changes in crime rates, prison admissions and time served. If criminal justice policies remained the same as they were in 1984, State imprisonment rates would have actually 20 declined by 7 percent by 2004, given falling crime rates. Instead, State prison rates increased by over 125 percent. After accounting for falling crime rates, over two-thirds of this increase was attributable to rising prison admission rates, and 14 percent to increases in time served. In Federal prisons, longer sentences and rising admissions rates have been equally important, each accounting for approximately 20 percent of the growth in the Federal prison rate that is not due to changes in crime…

That is from pp.19-20.  Here is a related post from last year.

Here is a very good point:

…the importance of maps to the self-driving market is another reason that car companies may struggle to remain market leaders as the industry shifts to fully autonomous technologies. Google, Apple, and Uber have a lot of experience collecting, analyzing, and distributing vast quantities of fast-changing geographic data. Ford, GM, and Toyota don’t.

The rest of the analysis by Timothy B. Lee is interesting as well.

There is a new paper by Kristin L. Leimgruber, Alexandra G. Rosati, and Laurie R. Santos, here is the abstract:

Punishment of non-cooperators is important for the maintenance of large-scale cooperation in humans, but relatively little is known about the relationship between punishment and cooperation across phylogeny. The current study examined second-party punishment behavior in a nonhuman primate species known for its cooperative tendencies—the brown capuchin monkey (Cebus apella). We found that capuchins consistently punished a conspecific partner who gained possession of a food resource, regardless of whether the unequal distribution of this resource was intentional on the part of the partner. A non-social comparison confirmed that punishment behavior was not due to frustration, nor did punishment stem from increased emotional arousal. Instead, punishment behavior in capuchins appears to be decidedly social in nature, as monkeys only pursued punitive actions when such actions directly decreased the welfare of a recently endowed conspecific. This pattern of results is consistent with two features central to human cooperation: spite and inequity aversion, suggesting that the evolutionary origins of some human-like punitive tendencies may extend even deeper than previously thought.

So long, good Samaritans.

In the first study of its kind, Cornell sociologists have found that people who have a medical emergency in a public place can’t necessarily rely on the kindness of strangers. Only 2.5 percent of people, or 1 in 39, got help from strangers before emergency medical personnel arrived, in research published April 14 in the American Journal of Public Health.

For African-Americans, these dismal findings only get worse. African-Americans were less than half as likely as Caucasians to get help from a bystander, regardless of the type of symptoms or illness they were suffering – only 1.8 percent, or fewer than 1 in 55 African-Americans, received assistance. For Caucasians, the corresponding number was 4.2 percent, or 1 in 24.

People in lower-income and densely populated counties were also less likely to get help, the researchers said. Conversely, those in less-densely populated counties with average socioeconomic levels were most likely to get assistance.

Singapore, 5 May 2015 – The Graciousness Index has continued to move up, from 53 in 2013 to 55 in 2014, and to 61 in 2015. This year’s rise is led by a growing sense of positive perceptions about kindness and graciousness in Singapore, with respondents rating both themselves and others higher when it comes to being considerate, courteous and showing appreciation.

The Graciousness Index is an annual study commissioned by the Singapore Kindness Movement to track experience and perceptions of kindness and graciousness in Singapore, as well as study attitudes towards various pertinent community issues. Over a six-week period from December 2014 to February 2015, a demographically representative sample of 1,850 respondents was asked to share their experiences and perceptions of graciousness in Singapore.

There was a marked increase in optimism, with 44% of respondents indicating that graciousness in Singapore had improved, compared to just 28% last year. 84% rated their own gracious behaviour as either good or excellent, and 69% felt the same about overall Singapore society. They also felt that Singapore was improving across the graciousness pillars of being considerate, being courteous and showing appreciation to others.

Dr. William Wan, General Secretary of the Singapore Kindness Movement, believes that this is a promising sign. “The increase in positive perceptions and overall sense of improvement is encouraging. If we as a nation continue this positive trend, then kindness and graciousness can become part of our norms and national identity.”

That which cannot be measured…
