""Compared with a healthy economy, about 7 million working-age people and 5 percent of the nation’s industrial capacity are sitting idle, not producing what they could. The economy is growing again, but at a rate — less than 2 percent in recent months — that’s too slow to keep up with a population that keeps increasing and workers who keep getting more efficient.
This is the output gap, the divide between the amount the United States can produce and what it is actually producing. The gap, currently $900 billion, explains why we feel so miserable more than a year into what is technically classified as an economic recovery.""
""Roughly 18 months after Frito-Lay, with great fanfare, launched a biodegradable SunChips bag made from plant material that was billed as 100% compostable, the company is yanking the noisy material from the packages of five of six SunChips flavors immediately.
The company is returning them to their former bags that can't be recycled — but won't wake the neighbors — while it works frantically to come up with a new, quieter eco-friendly bag.
The noise of the bag — due to an unusual molecular structure that makes the bag more rigid — has been compared to everything from lawnmowers to jet engines. There's even an active Facebook group with more than 44,000 friends that goes by the name of "Sorry But I Can't Hear You Over This SunChips Bag."
"Clearly, we'd received consumer feedback that it was noisy," says Aurora Gonzalez, a Frito-Lay spokeswoman. "We recognized from the beginning that the bag felt, looked and sounded different..."(Source HERE)

From today's LA Times: Automation is increasingly reducing U.S. workforces
"Forced to cut costs during the recession, employers across the country are looking at ways to avoid hiring. They've accelerated use of computers and technology, replacing administrative assistants with software, cashiers with self-service kiosks and laborers with machines.
These structural changes mean some jobs that disappeared during the recession may never come back. Productivity gains are good for company profits and help the economy grow over the long run. But in the short term, the shift is exacerbating America's jobless recovery.
"Recessions tend to act as ratchets; they'll often speed the pace of fundamental changes that were going on in the economy anyway," said Erica Groshen, vice president and director of regional affairs at the Federal Reserve Bank of New York.
Ditching workers is an appealing prospect to many California farmers. Few states have minimum wages higher than California's $8 an hour. The heightened focus on workers' immigration status has increased farmers' administrative burden.
With the help of machines, though, growers can continue to boost output while reducing headcount. Farm labor in California has fallen 11% over the last decade, yet cultivation of heavily automated crops soared over the same period: almond production has more than doubled, to 1.6 billion pounds.
"If cheap technology is available, you substitute technology for people," said Allen Sinai, chief global economist at Decision Economics in Boston.
Automation has been a steady progression since the Industrial Revolution. Still, laying off workers is never easy. Recessions give companies a motive to move more swiftly than they otherwise might have to cut staff, outsource work to cheaper locations and implement labor-saving technology, Sinai said. When sales pick up, companies can help profits rise quickly by keeping a lid on hiring.
That's part of the reason that earnings at some large companies have soared over the last year while job creation has lagged behind. In August, U.S. private sector employers added 67,000 jobs, far fewer than the 100,000 needed to keep pace with population growth."
""Election time in Brazil once meant wondering whether the nation's historically skittish currency would crash. This time around, policy makers are wrestling with a different problem: Money so strong they fear it may hinder the country's export-driven economic.."
The first graph below shows the Market for the Brazilian Real ("BRL") at equilibrium. I will use the US Dollar as the other currency, but it could be any other currency. Notice in the Market for BRL we price it in dollars ("USD/R$*). You should literally read this as "the dollar price per BRL" or more simply "How many dollars does it take to BUY ONE BRL". To keep it simple, let's assume the exchange rate is $1.00USD can buy R$1.00 and vice versa. In other words the currencies trade at parity."For example, Brazil's 10.75% overnight interest rate is among the highest in the world. That encourages speculators to borrow in the U.S. and Japan where money is cheap, deposit it in Brazil, and pocket the difference. This so-called carry trade pumps up the real by attracting a flood of dollars."

"If you've taken nine or more Advanced Placement tests, you're more than twice as likely to be admitted into an elite school as applicants who have taken no AP tests.
With nine or more AP tests, your chances are 36.2 percent. With three AP tests, they're 20.9 percent. With none, they're 15 percent. Number of AP tests taken "is a proxy for 'rich white kids,'" says O'Shaughnessy. "If you're a rich white kid, you have more access to APs. You're going to attend a high school where people live and breathe APs. You've got an advantage.”"

""NY Daily News -- New York City will change the lettering on every single street sign - at an estimated cost of about $27.5 million - because the feds don't like the font. Street names will change from all capital letters to a combination of upper and lower case on roads across the country thanks to the pricey federal regulation (see photo above). By 2018, MADISON AVE. will become Madison Ave. and will be printed in a font called Clearview, the city Department of Transportation says. The Federal Highway Administration says the switch will improve safety because drivers identify the words more quickly when they're displayed that way - and can sooner return their eyes to the road."

""Now, if James Goodfellow is part of society, we must conclude that society, considering its labors and its enjoyments, has lost the value of the broken window. From which, by generalizing, we arrive at this unexpected conclusion: "Society loses the value of objects unnecessarily destroyed," and at this aphorism, which will make the hair of the protectionists stand on end: "To break, to destroy, to dissipate is not to encourage national employment," or more briefly: "Destruction is not profitable."""
""The multi-millionaire owner of the Segway company died in a freak accident yesterday when he rode one of the high-tech two-wheel machines off a cliff and into a river.
Former miner Jimi Heselden, 62, plunged into the River Wharfe while riding around his West Yorkshire estate in Boston Spa on a rugged country version of the Segway.
He bought the firm last December and was using one of the machines - which use gyroscopes to remain upright and are controlled by the direction in which the rider leans - to inspect the grounds of his property.""
