RENEE MONTAGNE, HOST:

The electric car company Tesla recently took the unusual step of effectively giving up all its patents. That means any competitor is now free to take the company's ideas and run with them. David Kestenbaum with our Planet Money team looked at why Tesla did it and what the world might be like if we got rid of patents altogether.

DAVID KESTENBAUM, BYLINE: Back in 2007, I road in an early Tesla prototype with the guy who is now the company's CEO, Elon Musk.

"By taking better care of our coworkers," says Rob Olson, the acting president of Ikea U.S., "they will take better care of our customers, who will take better care of Ikea. We see it as a win-win-win opportunity."

Peanut Butter M&M's are larger and more irregular than standard M&M's.

The other day I went down to the little shop in the lobby of our building for a snack. I couldn't decide whether I wanted regular M&M's or Peanut Butter M&M's so I bought them both. On the way back upstairs to the office, I noticed something strange on the labels. Each had cost $1, but the pack of Peanut Butter M&M's was a very tiny bit lighter: 0.06 ounces lighter!

I wanted to know why, so I called a couple of experts and asked for their theories:

Theory No. 1: Peanut Butter M&M's are more expensive to make.

President Obama has called for increasing the minimum wage, saying it will help some of the poorest Americans. Opponents argue that a higher minimum wage will lead employers to cut jobs.

Figuring out the effect of raising the minimum wage is tough. Ideally you'd like to compare one universe where the minimum was raised against an alternate universe where it remained fixed.

The Birth Of The Minimum Wage In America

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

Franklin D. Roosevelt Libarary

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