The Birth Of The Minimum Wage In America

Franklin D. Roosevelt Libarary

Originally published on Fri January 17, 2014 4:46 pm

In 1895, legislators in New York state decided to improve working conditions in what at the time could be a deadly profession: baking bread.

"Bakeries are actually extremely dangerous places to work," says Eric Rauchway, a historian at the University of California, Davis. "Because flour is such a fine particulate, if it gets to hang in the air it can catch fire and the whole room can go up in a sheet of flame."

A Bet, Five Metals And The Future Of The Planet

This famous bet — between a biologist and an economist — was over population growth. It started three decades ago, but it helped set the tone for environmental debates that are still happening today.

The biologist at the heart of this bet was Paul Ehrlich at Stanford. He wrote a best-selling book in 1968 called The Population Bomb. It was so popular he appeared on The Tonight Show with Johnny Carson.

We recently published a story about how used clothes that get donated in the U.S. often wind up for sale in markets in Africa. As part of the story, we published some photos of used T-shirts we found in a couple of markets in Kenya.

One shirt in particular caught our eye:

Gavin Andresen is chief scientist at the Bitcoin Foundation. I first talked with him about Bitcoin, the virtual currency, back in 2011. I checked back in with him this week, because so much has been going on with Bitcoin lately.

What's A Bubble?

Robert Shiller and Eugene Fama shared this year's Nobel Memorial Prize.
AP

Originally published on Sun November 17, 2013 1:58 pm

Robert Shiller was surprised when he got the call telling him he'd won the Nobel Memorial Prize in economics — surprised that he'd won (of course), but also surprised that he was sharing the award with Eugene Fama.

"He and I seem to have very different views," Shiller told me. "It's like we're different religions."

In particular, they have very different views about economic bubbles.

"The word 'bubble' drives me nuts, frankly," Fama told me.

What A U.S. Default Would Mean For Pensions, China And Social Security

Originally published on Thu October 10, 2013 12:38 pm

What would happen if Congress doesn't raise the debt ceiling and the U.S. defaults on its debt later this month? The broad economic implications are unpredictable, but a default could cause huge trouble for the global economy.

But whatever happens to the global economy, one thing is clear: People all over the world who have loaned the U.S. government money won't get paid on time.

An Aerogramme From Professor Higgs, Nobel Winner

Letter from Peter Higgs
David Kestenbaum NPR

Originally published on Tue October 8, 2013 6:02 pm

Well, it's happened. British scientist Peter Higgs has won a Nobel Prize for proposing the Higgs boson particle as part of a mechanism that explains how things in the universe came to have mass.

Higgs seems to be lying low today so far — a colleague told The New York Times that Higgs had "gone off by himself for a few days without saying where" and that a reporter seeking an interview recently had been "sent away with a flea in his ear."

One Key Thing No One Knows About Obamacare

Tuesday is a big day for Obamacare. The online marketplaces where people can shop for health insurance are supposed to open for business.

No one really knows who is going to sign up — not the Obama administration, not the insurance industry, not the president's critics. Yet the success of the law hangs on this question: Will the right mix of people sign up? In particular, will healthy people buy health insurance?

Why Doesn't Everybody Buy Cheap, Generic Headache Medicine?

Same pills. Lower price.
Paul Sancya AP

Originally published on Fri July 5, 2013 9:03 pm

Why does anyone buy Bayer aspirin — or Tylenol, or Advil — when, almost always, there's a bottle of cheaper generic pills, with the same active ingredient, sitting right next to the brand-name pills?

Matthew Gentzkow, an economist at the University of Chicago's Booth school, recently tried to answer this question. Along with a few colleagues, Gentzkow set out to test a hypothesis: Maybe people buy the brand-name pills because they just don't know that the generic version is basically the same thing.

Economists Have A One-Page Solution To Climate Change

CX Matiash AP

Originally published on Fri June 28, 2013 10:45 am

Climate change seems like this complicated problem with a million pieces. But Henry Jacoby, an economist at MIT's business school, says there's really just one thing you need to do to solve the problem: Tax carbon emissions.

"If you let the economists write the legislation," Jacoby says, "it could be quite simple." He says he could fit the whole bill on one page.

Basically, Jacoby would tax fossil fuels in proportion to the amount of carbon they release. That would make coal, oil and natural gas more expensive. That's it; that's the whole plan.

A Surprising Barrier To Clean Water: Human Nature

Rodan Gatia gets water from a spring. A chlorine dispenser is behind her.

In many parts of the developing world, drinking a glass of water can be deadly — especially for young children, who can die of diarrheal diseases contracted from dirty water.

So getting clean water to people in the developing world has been a top priority for aid groups for a long time. But it's been a surprisingly hard problem to solve.

Lady Gaga Writing A New Song Is Like A Factory Investing In A New Machine

But is it GDP?
Charles Sykes AP

Originally published on Fri April 26, 2013 2:46 am

I spoke yesterday with Dan Sichel, a Wellesley economist and a Lady Gaga fan. Both of these facts are relevant for this story.

The U.S. government is about to tweak the way it measures the economy, and some of the biggest changes will affect the entertainment industry.

Under the current system, Sichel told me, Lady Gaga's sales of concert tickets, online songs and CDs all count toward gross domestic product. But the value of the time she spends in the studio working on new songs isn't counted. That's about to change.
