These data confirm that people essentially cannot close the wage gap by working their way up the company hierarchy.

At its peak, the Zambia Consolidated Copper Mines company employed more than 65,000 Zambians and carried out services like water delivery and waste collection for five cities in the Copper Belt Province.

Mining employment has dropped to just 30,000, half of its glory-days peak, and the job of maintaining all that company housing and infrastructure has reverted back to the government.

The stats identify Switzerland as Zambia’s primary export market. This is not an indicator that Zambia hosts a thriving chocolate and suspenders sector, but rather that its copper trades are booked in the jurisdiction where they are least likely to be taxed.

Many of the mining companies pay just 0.6 percent royalties to Zambia, far below the already-meager industry standard of three percent.

This is Namwile Uzondile, the director of a rural health education project.

Last year Namwile conducted a survey of prostitutes here in Kitwe, and found that at least half of them had education certificates, but couldn’t find work. Most had been married off early, 15 or 16, and since then had either left their husbands or lost them to AIDS.

First, you go to the tribal chief. Ninety-four percent of the land in Zambia is customary or traditional, no one has a title to it. It’s not just sitting there, people are living on it, farming, grazing animals, it’s just technically under the control of a chief.

In Zambia most of the chiefs require a gift just to get a meeting. This might mean taking them lunch at a restaurant in Lusaka, or it could mean buying their daughter a car—it’s up to them.

Another reason Zambia lacks skills is that some parts of the workforce operate as cartels. Take lawyers. Zambia only has 1,000 of them, and they’re concentrated where the money is: Lusaka (government), Copper Belt (mining) and Livingstone (safari tourists).

Last year, only six lawyers were admitted to the bar out of 164 who took the exam. The year before that, it was 16 out of 145. Keep in mind, these aren’t people coming in off the streets. These are people who have a law degree.

More than 60 percent of Zambia’s government revenue comes from the copper mines.

Taxing all this informal activity would be costly in both resources and voter goodwill. In 2012, Zambia collected just $2.3 million in income taxes from its citizens.

It goes as high up as you want to follow it. Michael Sata, the president of Zambia, appointed his uncle the finance minister, his nephew the deputy finance minister, his niece the local government minister, and cousins as ambassador to Japan and chief justice.

Zambia’s cabinet has ballooned to 20 ministers and 47 deputy ministers, the largest in Africa. With salaries three to four times higher than opposition MPs and each ministerial post bundled with perks like a company car, free fuel, house servants, and mobile phone talk-time, you get the feeling politicians aren’t jumping from opposition into government on moral sentiment alone.

In 2011, Zambia spent a total of $4.3 billion running itself. Stretch that to cover every man, woman, and child, and it amounts to just $325 per person per year. That amount—less than a dollar per person per day—has to cover education, health care, infrastructure, law enforcement, foreign debt … everything.

Now she goes all NGO. “Little government capacity,” she says, is the nicest way to put it. “There are simply no systems for routine government services,” she says. Getting a license, a permit, certificates, approvals to start work, visas for expats to fly down here—nothing is in one place, nothing is fast or easy.

“Sometimes we have to pay for the inspectors to come to our mines,” Jane says.

The conversation goes like this: Jane tells the local certification body that she needs an inspector to sign off for a permit. The local certification body tells her that they would be happy to come out to the site, but they don’t have fuel for their cars, or enough petty cash to pay per diems. Jane offers to pay their costs, but only their costs, and the payments aren’t related to clearing the inspection.

The company has even paid the police to follow up on complaints or to investigate thefts. “They say, ‘We don’t have this in our budget’ or ‘We’ll need you to pay for it,’” Jane says. So the company fixes the police cars, covers their travel expenses, treats them to lunch.

“We tell them, ‘The company I work for, we’re not going to pay up.’ But at the end of the day, they know you’re on a short timeline, and they aren’t.”

Thomas’ family told him his nephews didn’t need to be in school. From their perspective, that’s not totally irrational. In a country with so few formal jobs and so much competition for getting them, I can see how spending hundreds of hours, thousands of kwachas, on education would seem superfluous. Thomas’ daughter wants to become a lawyer. You could almost forgive Thomas if he told her that the bar exam failure rate is more than 90 percent, so what’s the use?

International investors pledged $750 million last year to build infrastructure.

“One of the best management techniques for controlling Goss’s wilt is crop rotation — corn, then soy or another crop,” Mr. Anderson said.

nother possible factor is the growth of no-till farming, which leaves cornstalks, on which the bacteria can linger, to decay in the field after harvesting, rather than being plowed under.

The U.S.D.A. must consider salmonella that’s been linked to illness an “adulterant” (as it does strains of E. coli), which would mean that its very presence on foods would be sufficient to take them off the market. Again, it’s almost as simple as that. (Sweden produces chicken with zero levels of salmonella. Are they that much smarter than us?)

In 2005 its government brought in fertiliser subsidies. It reported a maize crop of 3.4m tonnes in 2006-7, up from 2.6m tonnes the year before. The aid lobby said this justified the subsidies and the budget support which enables them to be paid for.

The relocation of some production to Spain has already created 1,300 new jobs in a region that is in far worse economic shape than the area around Genk, although Ford said labor costs in Valencia are not significantly lower.

Like many in Genk, Mr. Maurina and his wife, Sabrina Gattanella, who have two young boys, are descendants of Italians who migrated to the region decades ago to work in the coal mines. But the last mine closed in the 1980s.

“There has been a significant reduction in demand over four or five years, and we don’t see robust demand in the future.”

As US coal demand declines, more US coal is going to Europe, where low CO2 prices and high gas prices are increasing the competitiveness of coal in the power generation system.

The authors come up with a variety of numbers, including one that has received a lot of attention: potential G.D.P.—broadly speaking, the level of G.D.P. consistent with stable inflation—“is currently about 7 percent below the trajectory it appeared to be on prior to 2007.” According to the latest figures from the Commerce Department, the G.D.P. is now close to seventeen trillion dollars, and seven per cent of that figure is $1.2 trillion. This is a lot of money to have gone missing, especially if it will never be recovered. Hence Krugman’s dire conclusion: “By tolerating high unemployment we have inflicted huge damage on our long-run prospects …. What passes these days for sound policy is in fact a form of economic self-mutilation, which will cripple America for many years to come.”

As well as figuring out the current level of potential G.D.P., the authors estimate its growth rate. This is the more important figure, because it’s what determines living standards over the long term

In the nineteen-eighties, Larry Summers and Olivier Blanchard, who is now the chief economist of the I.M.F., resurrected the idea and gave it a new name, which they borrowed from engineering: hysteresis. Blanchard and Summers examined hysteresis in Europe, where high rates of unemployment have long been a problem.

The good news is that things aren’t quite as bad as the figures in the Fed paper might suggest. If we can get policy right and sharply increase the level of over-all demand in the economy, most of the damage done in the past five years is reversible.

At the moment, sadly, there is no prospect of any more fiscal stimulus, let alone a war-sized one, and the onus is falling on the Fed to gee up the economy.

The Arctic Council's 2009 report estimated that the NSR offers from a 35 percent to 60 percent savings in distance for ships traveling between Europe and the Far East. Ships also can circumvent regional conflicts and the risk of piracy near the coast of Africa or in the Straits of Malacca off Malaysia.

Hiring charges for mandatory escort by Rosatomflot's icebreakers vary, but the average cost is about $200,000,

the cost of escort through the NSR is roughly equivalent to that of passage through the Suez Canal.

Because "container" shipping of goods, (as opposed to bulk shipping of raw commodities like ores and fuel), relies heavily on on-time delivery, Carmel thinks it unlikely the NSR ever will become a major pathway for this kind of global commerce.

primary focus on the 22 percent of the world's remaining undiscovered oil and natural gas resources to be found in the far north.
