Coming Full Circle in Energy, to Nuclear - NYTimes.com - 0 views

  • In a typical day, Mr. Durgin tells me, 21 trains depart the mine, pulling 135 cars each. Each car bears 120 tons of coal. At this pace, he says, there is more than 20 years’ worth of coal ready to mine under my feet.
  • North Antelope Rochelle is among the biggest coal mines in the world. It produced 108 million tons last year — about 10 percent of all the coal burned by the nation’s power plants.
  • North Antelope Rochelle and the other vast strip mines cutting through the plains of Wyoming’s Powder River Basin — whose low-sulfur carbon met standards imposed by the Clean Air Act — were the result

  • Today renewable energy supplies only about 6 percent of American demand. And most of that comes from water flowing through dams. Solar energy contributes next to nothing.
  • The arithmetic is merciless. To make it likely that the world’s temperature will rise no more than 2 degrees Celsius above the average of the preindustrial era — a target agreed to by the world’s governments in 2010 — humanity must spew no more than 900 billion more tons of carbon dioxide into the air from now through 2050 and only 75 billion tons after that, according to an authoritative new study in Britain.
  • The United States Energy Information Administration forecasts that global energy consumption will grow 56 percent between now and 2040.
  • “We have trillions of tons of coal resources in the world,” Vic Svec, spokesman for Peabody Energy, told me. “You can expect the world to use them all.”
  • The only way around this is to put something in coal’s place, at a reasonably competitive price. Neither the warm glow of the sun nor the restless power of the wind is going to do the trick, at least not soon enough to make a difference in the battle to prevent climate change.

Some thoughts on German politics and the saver's tax in Cyprus | Credit Writedowns - 0 views

  • Now, the large 82.8% German government debt to GDP ratio is a source of shame for many because Germany was a driving force in enshrining the 60% government debt to GDP hurdle into the Maastricht Treaty that set out terms for the euro zone.
  • Moreover, the interest rate policy of the ECB, geared as it was to the slow growth core, produced negative real interest rates and credit bubbles in Spain and Ireland during the last decade. German banks piled in to those countries as prospects domestically stagnated.
  • “The average German worker feels like a cash cow being sucked dry by a quick succession of reforms and bailouts that take money out of her pocket. First it was for reunification, then for European integration, then to right the economy, then to bail out German banks, and finally to bail out the European periphery. Fatigue has set in.”
  • ...10 more annotations...
  • The bottom line is that none of the major political parties in Germany are going to vote for bailouts for other euro zone countries unless massive strings are attached, since these bailouts are political losers.
  • The anti-bailout part of the FDP platform is the one part of their rhetoric which could successfully take them over the 5% hurdle. The FDP’s complicity in using German taxpayer money to bail out the so-called profligate periphery is a one-way ticket out of Parliament.
  • “First, the Greek reports come via statements made by Michael Fuchs, CDU deputy Bundestag head and a senior member of German Chancellor Angela Merkel’s party. Fuchs warned earlier today that Germany would veto further aid to Greece if the country has not met the conditions of its previous bailouts.
  • “Second, all along Germany has indicated that it is resistant to increasing funding of the ESM and EFSF bailout facilities. This presents a problem in the case of Spain and Italy because of the size of those economies.
  • Willem Buiter, Chief Economist at Citigroup, has been most vocal in predicting that these facilities will be inadequate when Spain and Italy hit the wall and that more extreme measures will have to be taken.
  • The basic dilemma here is that almost all of the eurozone governments including Germany carry high debt burdens in excess of the Maastricht Treaty. For example, Germany has been in breach of Maastricht Treaty in 8 of 10 years since 2002, has been over the Maastricht 60% hurdle in each of those ten years, and now carries a debt to GDP burden above 80%.
  • The long and short of it was that the Germans had reached the end of their ability to support bailouts.
  • All evidence is that this levy has created panic in Cyprus. After all, what is the use of having a deposit guarantee if government can arbitrarily circumvent it to impose losses on your deposits anyway?
  • One can't just blame Cyprus for this fiasco. The ECB, EC and European Union finance ministers signed off on the insured deposit grab too]
  • My view? It was inevitable that we would be in crisis again. The austerity world view of crisis resolution is completely at odds with the capacity of the euro zone’s institutional architecture to handle a crisis.

Robert Samuelson: A dishonest budget debate - The Washington Post - 0 views

  • t’s the math: In fiscal 2012, Social Security, Medicare, Medicaid and civil service and military retirement cost $1.7 trillion, about half the budget.

  • In a Pew poll, 87 percent of respondents favored present or greater Social Security spending; only 10 percent backed cuts. Results were similar for 18 of 19 programs, foreign aid being the exception.
  • an aging America needs a new social compact: one recognizing that longer life expectancies justify gradual increases in Social Security’s and Medicare’s eligibility ages; one accepting that sizable numbers of well-off retirees can afford to pay more for their benefits or receive less; one that improves generational fairness by concentrating help for the elderly more on the needy and poor to lighten the burdens — in higher taxes and fewer public services — on workers; and one that limits health costs.

  • As soon as the paper was released, many economists pointed out that a negative correlation between debt and economic performance need not mean that high debt causes low growth.
  • and the mystery of the irreproducible results was solved. First, they omitted some data; second, they used unusual and highly questionable statistical procedures; and finally, yes, they made an Excel coding error.

Read, I, Pencil | Library of Economics and Liberty - 0 views

  • Simple? Yet, not a single person on the face of this earth knows how to make me.
  • Not much meets the eye—there's some wood, lacquer, the printed labeling, graphite lead, a bit of metal, and an eraser.
  • a cedar of straight grain that grows in Northern California and Oregon
  • ...16 more annotations...
  • The logs are shipped to a mill in San Leandro, California.
  • The slats are waxed and kiln dried again.
  • The cedar logs are cut into small, pencil-length slats less than one-fourth of an inch in thickness. These are kiln dried and then tinted for the same reason women put rouge on their faces.
  • Don't overlook the ancestors present and distant who have a hand in transporting sixty carloads of slats across the nation.
  • Once in the pencil factory—$4,000,000 in machinery and building, all capital accumulated by thrifty and saving parents of mine—each slat is given eight grooves by a complex machine, after which another machine lays leads in every other slat, applies glue, and places another slat atop—a lead sandwich, so to speak. Seven brothers and I are mechanically carved from this "wood-clinched" sandwich.
  • The graphite is mined in Ceylon.
  • The graphite is mixed with clay from Mississippi in which ammonium hydroxide is used in the refining process. Then wetting agents are added such as sulfonated tallow—animal fats chemically reacted with sulfuric acid. After passing through numerous machines, the mixture finally appears as endless extrusions—as from a sausage grinder-cut to size, dried, and baked for several hours at 1,850 degrees Fahrenheit. To increase their strength and smoothness the leads are then treated with a hot mixture which includes candelilla wax from Mexico, paraffin wax, and hydrogenated natural fats.
  • My cedar receives six coats of lacquer. Do you know all the ingredients of lacquer? Who would think that the growers of castor beans and the refiners of castor oil are a part of it? They are.
  • Observe the labeling. That's a film formed by applying heat to carbon black mixed with resins. How do you make resins and what, pray, is carbon black?
  • My bit of metal—the ferrule—is brass. Think of all the persons who mine zinc and copper and those who have the skills to make shiny sheet brass from these products of nature. Those black rings on my ferrule are black nickel. What is black nickel and how is it applied? The complete story of why the center of my ferrule has no black nickel on it would take pages to explain. RP.18
  • An ingredient called "factice" is what does the erasing. It is a rubber-like product made by reacting rape-seed oil from the Dutch East Indies with sulfur chloride. Rubber, contrary to the common notion, is only for binding purposes. Then, too, there are numerous vulcanizing and accelerating agents. The pumice comes from Italy; and the pigment which gives "the plug" its color is cadmium sulfide
  • Actually, millions of human beings have had a hand in my creation, no one of whom even knows more than a very few of the others.
  • There isn't a single person in all these millions, including the president of the pencil company, who contributes more than a tiny, infinitesimal bit of know-how.
  • Here is an astounding fact: Neither the worker in the oil field nor the chemist nor the digger of graphite or clay nor any who mans or makes the ships or trains or trucks nor the one who runs the machine that does the knurling on my bit of metal nor the president of the company performs his singular task because he wants me.
  • There is a fact still more astounding: the absence of a master mind, of anyone dictating or forcibly directing these countless actions which bring me into being. No trace of such a person can be found.
  • For, if one is aware that these know-hows will naturally, yes, automatically, arrange themselves into creative and productive patterns in response to human necessity and demand—that is, in the absence of governmental or any other coercive masterminding—then one will possess an absolutely essential ingredient for freedom: a faith in free people. Freedom is impossible without this faith.

European Union Leaders Gather in Brussels Over Budget - NYTimes.com - 0 views

  • He has threatened to veto any new budget that does not at least freeze spending,
  • “Europeans who are attached to the European Union are now in a minority.” Fifty-two percent of those surveyed said they felt little or no attachment, up seven percentage points since 2010. In Britain, only 27 percent felt attached to the union.
  • Ahead of this week’s negotiations, at least seven countries, mostly those that contribute more to Europe’s coffers than they get back in farm subsidies and other payments, have already warned that they may veto a budget that does not give them a better deal. Among these is Austria, where, according to Mr. Ehrenhauser, who sits on the European Parliament’s budgetary control committee, “there is a critical mass building against the European Union.”
  • ...5 more annotations...
  • The rethink, which would have scrapped spending on agricultural subsidies, ran into heavy opposition and stalled
  • All long-term budget decisions require unanimous approval by the member states, a rule first established when the grouping, then known as the European Economic Community, had just six members, not 27. The power of veto makes any major change to spending all but impossible and entrenches the status quo, no matter how unworkable or unpopular.
  • “It is extremely difficult to change anything,” Mr. Sapir said. “Everyone is always fighting at the margins over narrow national interests. They try to make sure they get money for their own countries and that cuts go to other countries.”
  • After months of arguments, two broad alliances have emerged. The first comprises countries like Britain, Germany and Sweden that are big net contributors and want to keep a tighter rein on spending. The second, known as the “Friends of Cohesion,” after a class of development grants aimed at less wealthy areas, includes Poland, Spain, Portugal and others that want to make sure the union’s largess does not dry up.
  • The European Commission, however, has been far less forthcoming. It told Mr. Ehrenhauser that it could not give a breakdown of spending in recent years on wine because that would require “lengthy research” and “it cannot consider doing this at the present time because of other priorities.”

Deepening divide over Elbe dredging | Germany | DW.COM | 19.12.2016 - 0 views

  • Deepening divide over Elbe dredging
  • The Marco Polo, for example, carries 16,000 containers and has a draft (the vertical distance between waterline and ship's keel) of 16 meters. Given present river depths and tides, such ships can only enter Hamburg at certain times and when not fully loaded.
  • Tidal range is a prime cause for erosion, which previous river dredging, as well as waves generated by passing ships, have exacerbated
  • ...2 more annotations...
  • As the river deepens, more seawater from the North Sea flows at a faster rate towards Hamburg, bringing sediment that builds up on the riverbed. The Hamburg Port Authority dredges the river to counteract the build up, which cost taxpayers 120 million euros ($125 million) in 2015.
  • The two projects amount to an expensive redundancy, Siegert said, with the JadeWeserPort costing $1.6 billion and the Elbe project an additional $940 million. "This is the reason for our protest: They decided on the first port, and now they should coordinate traffic, so that the really large ships can go to Wilhelmshaven or, under certain restrictions, to Hamburg."

No ordinary recession: There is much to fear beyond fear itself | vox - 0 views

  • Richard Koo (2003) coined the term “balance sheet recession” to characterise the endless travail of Japan following the collapse of its real estate and stock market bubbles in 1990. The Japanese government did not act to repair the balance sheets of the private sector following the crash. Instead, it chose a policy of keeping bank rate near zero so as to reduce deposit rates and let the banks earn their way back into solvency. At the same time it supported the real sector by repeated large doses of Keynesian deficit spending. It took a decade and a half for these policies to bring the Japanese economy back to reasonable health.
  • At the time, a majority of forecasts predicted that the economy would slip back into depression once defence expenditures were terminated and the armed forces demobilised. The forecasts were wrong. This famous postwar “forecasting debacle” demonstrated how simple income-expenditure reasoning, ignoring the state of balance sheets, can lead one completely astray.
  • The lesson to be drawn from these two cases is that deficit spending will be absorbed into the financial sinkholes in private sector balance sheets and will not become effective until those holes have been filled.
  • ...9 more annotations...
  • The present administration, like the last, would like to recapitalise the banks at least partly by attracting private capital. That can hardly be accomplished as long as the value of large chunks of the banks’ assets remains anybody’s guess.
  • When the entire private sector is bent on shortening its balance sheet and paying down debt, the public sector’s balance sheet must move in the opposite, offsetting direction. When the entire private sector is striving to save, the government must dis-save. The political obstacles to doing these things on a sufficient scale are formidable.
  • The Swedish policy following the 1992 crisis has been often referred to in recent months. Sweden acted quickly and decisively to close insolvent banks, and to quarantine their bad assets into a special fund.2 Eventually, all the assets, good and bad, ended up in the private banking sector again. The stockholders in the failed banks lost all their equity while the loss to taxpayers of the bad assets was minimal in the end. The operation was necessary to the recovery but what actually got the economy out of a very sharp and deep recession was the 25-30% devaluation of the krona which produced a long period of strong export-led growth.
  • So the private sector as a whole is bent on reducing debt.

Tracing Germs Through the Aisles - NYTimes.com - 0 views

  • More than 70 percent of all the antibiotics used in the United States are given to animals.
  • Agribusiness groups disagree and say the main problem is overuse of antibiotic treatments for people. Bugs rarely migrate from animals to people, and even when they do, the risk they pose to human health is negligible, the industry contends.
  • He is comparing the genetic sequences of E. coli germs resistant to multiple antibiotics found in the meat samples to the ones that have caused urinary tract infections in people (mostly women).
  • ...5 more annotations...
  • Urinary infections were chosen because they are so common. American women get more than eight million of them a year. In rare cases the infections enter the bloodstream and are fatal.
  • A new strain of the antibiotic-resistant bug MRSA, for example, was first detected in people in Holland in 2003, and now represents 40 percent of the MRSA infections in humans in that country, according to Jan Kluytmans, a Dutch researcher. That same strain was common in pigs on farms before it was found in people, scientists say.
  • He thinks the Food and Drug Administration’s efforts to limit antibiotic use on farms have been weak. In 1977, the F.D.A. said it would begin to ban some agricultural uses of antibiotics. But the House and Senate appropriations committees — dominated by agricultural interests — passed resolutions against the ban, and the agency retreated. More recently, the agency has limited the use of two important classes of antibiotics in animals. But advocates say it needs to go further and ban use of all antibiotics for growth promotion. Sweden and Denmark have already done so.
  • Ms. Slaughter said aggressive lobbying by agribusiness interests has played a major role in blocking passage of legislation.
  • But the economics of food presents perhaps the biggest obstacle. On large industrial farms, animals are raised in close contact with one another and with big concentrations of bacteria-laden feces and urine. Antibiotics keep infections at bay but also create drug resistance.

What if the Secret to Success Is Failure? - NYTimes.com - 0 views

  • In the winter of 2005, Randolph read “Learned Optimism,” a book by Martin Seligman, a psychology professor at the University of Pennsylvania who helped establish the Positive Psychology movement.
  • Seligman and Peterson consulted works from Aristotle to Confucius, from the Upanishads to the Torah, from the Boy Scout Handbook to profiles of Pokémon characters, and they settled on 24 character strengths common to all cultures and eras. The list included some we think of as traditional noble traits, like bravery, citizenship, fairness, wisdom and integrity; others that veer into the emotional realm, like love, humor, zest and appreciation of beauty; and still others that are more concerned with day-to-day human interactions: social intelligence (the ability to recognize interpersonal dynamics and adapt quickly to different social situations), kindness, self-regulation, gratitude.
  • Six years after that first meeting, Levin and Randolph are trying to put this conception of character into action in their schools. In the process, they have found themselves wrestling with questions that have long confounded not just educators but anyone trying to nurture a thriving child or simply live a good life. What is good character? Is it really something that can be taught in a formal way, in the classroom, or is it the responsibility of the family, something that is inculcated gradually over years of experience? Which qualities matter most for a child trying to negotiate his way to a successful and autonomous adulthood? And are the answers to those questions the same in Harlem and in Riverdale?
  • ...13 more annotations...
  • According to a report that KIPP issued last spring, only 33 percent of students who graduated from a KIPP middle school 10 or more years ago have graduated from a four-year college.
  • As Levin watched the progress of those KIPP alumni, he noticed something curious: the students who persisted in college were not necessarily the ones who had excelled academically at KIPP; they were the ones with exceptional character strengths, like optimism and persistence and social intelligence. They were the ones who were able to recover from a bad grade and resolve to do better next time; to bounce back from a fight with their parents; to resist the urge to go out to the movies and stay home and study instead; to persuade professors to give them extra help after class.
  • “The thing that I think is great about the character-strength approach,” he told me, “is it is fundamentally devoid of value judgment.”
  • Duckworth’s early research showed that measures of self-control can be a more reliable predictor of students’ grade-point averages than their I.Q.’s.
  • People who accomplished great things, she noticed, often combined a passion for a single mission with an unswerving dedication to achieve that mission, whatever the obstacles and however long it might take. She decided she needed to name this quality, and she chose the word “grit.”
  • She and her team of researchers gave middle-school students at Riverdale and KIPP a variety of psychological and I.Q. tests. They found that at both schools, I.Q. was the better predictor of scores on statewide achievement tests, but measures of self-control were more reliable indicators of report-card grades.
  • Back at Riverdale, though, the idea of a character report card made Randolph nervous. “I have a philosophical issue with quantifying character,” he explained to me one afternoon. “With my school’s specific population, at least, as soon as you set up something like a report card, you’re going to have a bunch of people doing test prep for it. I don’t want to come up with a metric around character that could then be gamed. I would hate it if that’s where we ended up.”
  • Last winter, Riverdale students in the fifth and sixth grades took the 24-indicator survey, and their teachers rated them as well. The results were discussed by teachers and administrators, but they weren’t shared with students or parents, and they certainly weren’t labeled a “report card.”
  • The CARE program falls firmly on the “moral character” side of the divide, while the seven strengths that Randolph and Levin have chosen for their schools lean much more heavily toward performance character: while they do have a moral component, strengths like zest, optimism, social intelligence and curiosity aren’t particularly heroic; they make you think of Steve Jobs or Bill Clinton more than the Rev. Martin Luther King Jr. or Gandhi.
  • The topic for the assembly was heroes, and a half-dozen students stood up in front of their classmates — about 350 kids, in all — and each made a brief presentation about a particular hero he or she had chosen:
  • I came to Witter’s class to observe something that Levin was calling “dual-purpose instruction,” the practice of deliberately working explicit talk about character strengths into every lesson.
  • It is a central paradox of contemporary parenting, in fact: we have an acute, almost biological impulse to provide for our children, to give them everything they want and need, to protect them from dangers and discomforts both large and small. And yet we all know — on some level, at least — that what kids need more than anything is a little hardship: some challenge, some deprivation that they can overcome, even if just to prove to themselves that they can.
  • The idea of building grit and building self-control is that you get that through failure,” Randolph explained. “And in most highly academic environments in the United States, no one fails anything.”

  • Italy faces no immediate threat for as long interest rates remain low. The country will be able to muddle through for a while until some political or economic shock will force a decision one way or the other.
  • Meanwhile, the single largest constraint on the resumption of eurozone growth is not fiscal policy – which is broadly neutral at present across the single currency area – but the continued failure to clean up the banks. The growth rate of loans to the non-financial sector turned negative in 2009, showed some intermittent improvements, only to then deteriorate again last year.
  • The monetary and banking data are telling us that the economy will teeter on the brink of zero or low growth for the foreseeable future because the financial sector is not supplying the economy with sufficient funds to expand.
  • Banking union could help, but only if it were to break the relationship between banks and sovereigns and clean up the balance sheets.

Why Do Americans Stink at Math? - NYTimes.com - 0 views

  • Why Do Americans Stink at Math?
  • The Americans might have invented the world’s best methods for teaching math to children, but it was difficult to find anyone actually using them.
  • In fact, efforts to introduce a better way of teaching math stretch back to the 1800s. The story is the same every time: a big, excited push, followed by mass confusion and then a return to conventional practices.
  • ...25 more annotations...
  • Carefully taught, the assignments can help make math more concrete. Students don’t just memorize their times tables and addition facts but also understand how arithmetic works and how to apply it to real-life situations. But in practice, most teachers are unprepared and children are baffled, leaving parents furious.
  • On national tests, nearly two-thirds of fourth graders and eighth graders are not proficient in math. More than half of fourth graders taking the 2013 National Assessment of Educational Progress could not accurately read the temperature on a neatly drawn thermometer.
  • On the same multiple-choice test, three-quarters of fourth graders could not translate a simple word problem about a girl who sold 15 cups of lemonade on Saturday and twice as many on Sunday into the expression “15 + (2×15).” Even in Massachusetts, one of the country’s highest-performing states, math students are more than two years behind their counterparts in Shanghai.
  • A 2012 study comparing 16-to-65-year-olds in 20 countries found that Americans rank in the bottom five in numeracy.
  • On a scale of 1 to 5, 29 percent of them scored at Level 1 or below, meaning they could do basic arithmetic but not computations requiring two or more steps.
  • One study that examined medical prescriptions gone awry found that 17 percent of errors were caused by math mistakes on the part of doctors or pharmacists.
  • “I’m just not a math person,” Lampert says her education students would say with an apologetic shrug.
  • In the 1970s and the 1980s, cognitive scientists studied a population known as the unschooled, people with little or no formal education.
  • For instance, many of the workers charged with loading quarts and gallons of milk into crates had no more than a sixth-grade education. But they were able to do math, in order to assemble their loads efficiently, that was “equivalent to shifting between different base systems of numbers.”
  • Studies of children in Brazil, who helped support their families by roaming the streets selling roasted peanuts and coconuts, showed that the children routinely solved complex problems in their heads to calculate a bill or make change.
  • The cognitive-science research suggested a startling cause of Americans’ innumeracy: school.
  • Only when the company held customer focus groups did it become clear why. The Third Pounder presented the American public with a test in fractions. And we failed. Misunderstanding the value of one-third, customers believed they were being overcharged. Why, they asked the researchers, should they pay the same amount for a third of a pound of meat as they did for a quarter-pound of meat at McDonald’s. The “4” in “¼,” larger than the “3” in “⅓,” led them astray.
  • In the process, she gave them an opportunity to realize, on their own, why their answers were wrong.
  • At most education schools, the professors with the research budgets and deanships have little interest in the science of teaching
  • The answer-getting strategies may serve them well for a class period of practice problems, but after a week, they forget. And students often can’t figure out how to apply the strategy for a particular problem to new problems.
  • Some of the failure could be explained by active resistance.
  • A year after he got to Chicago, he went to a one-day conference of teachers and mathematicians and was perplexed by the fact that the gathering occurred only twice a year.
  • More distressing to Takahashi was that American teachers had almost no opportunities to watch one another teach.
  • In Japan, teachers had always depended on jugyokenkyu, which translates literally as “lesson study,” a set of practices that Japanese teachers use to hone their craft. A teacher first plans lessons, then teaches in front of an audience of students and other teachers along with at least one university observer. Then the observers talk with the teacher about what has just taken place. Each public lesson poses a hypothesis, a new idea about how to help children learn.
  • The research showed that Japanese students initiated the method for solving a problem in 40 percent of the lessons; Americans initiated 9 percent of the time.
  • Similarly, 96 percent of American students’ work fell into the category of “practice,” while Japanese students spent only 41 percent of their time practicing.
  • Finland, meanwhile, made the shift by carving out time for teachers to spend learning. There, as in Japan, teachers teach for 600 or fewer hours each school year, leaving them ample time to prepare, revise and learn. By contrast, American teachers spend nearly 1,100 hours with little feedback.
  • “Sit on a stone for three years to accomplish anything.”
  • In one experiment in which more than 200 American teachers took part in lesson study, student achievement rose, as did teachers’ math knowledge — two rare accomplishments.
  • Examining nearly 3,000 teachers in six school districts, the Bill & Melinda Gates Foundation recently found that nearly two-thirds scored less than “proficient” in the areas of “intellectual challenge” and “classroom discourse.”

  • Finally, to achieve debt sustainability for the eurozone sovereigns, radical supply side reforms are required that boost the growth rate of potential output to at least 1.5 per cent in Italy, Portugal and other sclerotic countries.

Learning about global value chains by looking beyond official trade data: Part 1 | vox - 0 views

  • Gross trade accounting: A transparent method to discover global value chain-related information behind official trade data: Part 1
  • With the rapid increase in intermediate trade flows, trade economists and policymakers have reached a near consensus that official trade statistics based on gross terms are deficient, often hiding the extent of global value chains. There is also widespread recognition among the official international statistics agencies that fragmentation of global production requires a new approach to measure trade, in particular the need to measure trade in value-added. This led the WTO and the OECD to launch a joint “Measuring Trade in Value-Added” initiative on 15 March 2012, which is designed to mainstream the production of trade in value-added statistics and make them a permanent part of the statistical landscape.
  • All the estimation methods used in recent efforts to measure trade in value-added are rooted in Leontief (1936). His work demonstrated that the amount and type of intermediate inputs needed in the production of one unit of output can be estimated based on the input-output structures across countries and industries.

  • If one is only interested in estimating the domestic value-added embedded in a country’s or sector’s gross exports, applying Leontief’s insight is sufficient. However, for many economic and policy applications, one also needs to quantify other components in gross exports and their structures. In such circumstances Leontief’s original insight is not sufficient, as it does not provide a way to decompose intermediate trade flows across countries into various value-added terms according to their final absorption,
  • Our gross trade accounting framework in fact allows one to further decompose each of the four major parts of gross exports above into finer components with economic interpretations
  • By the gross statistics, presented in column 1 of Table 1, the trade is highly imbalanced – Chinese exports to the US ($176.9 billion in 2011) are five times that of US exports to China ($35.1 billion in 2011). If we separate exports of final goods and of intermediate goods (reported in columns 2a and 2b of Table 1), we see that most of the Chinese exports consist of final goods, whereas most of the US exports consist of intermediate goods.
  • In other words, the US exports rely overwhelmingly on its own value-added (only 2.1% from China and 5.8% from other countries in 2011), whereas the Chinese exports use more foreign value-added, especially value-added from third countries (with 3.2% from the US and 23.1% from Japan, Korea, and all other countries).
  • As a consequence of these differences in the structure of value-added composition, the China–US trade balance in this sector looks much smaller when computed in terms of domestic value-added than in terms of gross exports.
  • By identifying which parts of the official data are double counted and the sources of the double counting, our gross trade accounting method provides a transparent way to bridge official trade statistics (in gross terms) and national accounts (in value-added terms) consistent with the System of National Accounts standard.
