TED Business

We make important decisions every day -- and we often rely on experts to help us decide. But, says economist Noreena Hertz, relying too much on experts can be limiting and even dangerous. She calls for us to start democratizing expertise -- to listen not only to "surgeons and CEOs, but also to shop staff."

Lisa Gansky, author of "The Mesh," talks about a future of business that's about sharing all kinds of stuff, either via smart and tech-enabled rental or, more boldly, peer-to-peer. Examples across industries -- from music to cars -- show how close we are to this meshy future.

Work-life balance, says Nigel Marsh, is too important to be left in the hands of your employer. Marsh lays out an ideal day balanced between family time, personal time and productivity -- and offers some stirring encouragement to make it happen.

Media and advertising companies still use the same old demographics to understand audiences, but they're becoming increasingly harder to track online, says media researcher Johanna Blakley. As social media outgrows traditional media, and women users outnumber men, Blakley explains what changes are in store for the future of media.

In this short talk, Arianna Huffington shares a small idea that can awaken much bigger ones: the power of a good night's sleep. Instead of bragging about our sleep deficits, she urges us to shut our eyes and see the big picture: We can sleep our way to increased productivity and happiness -- and smarter decision-making.

The future of green is local -- and entrepreneurial. In her talk, Majora Carter brings us the stories of three people who are saving their own communities while saving the planet. Call it "hometown security." (Filmed at TEDxMidWest.)

Facebook COO Sheryl Sandberg looks at why a smaller percentage of women than men reach the top of their professions -- and offers 3 powerful pieces of advice to women aiming for the C-suite.

In her talk, Rachel Botsman says we're "wired to share" -- and shows how websites like Zipcar and Swaptree are changing the rules of human behavior.

If you've been in a restaurant kitchen, you've seen how much food, water and energy can be wasted there. Chef Arthur Potts-Dawson shares his very personal vision for drastically reducing restaurant, and supermarket, waste -- creating recycling, composting, sustainable engines for good (and good food).

William Ury, author of "Getting to Yes," offers an elegant, simple (but not easy) way to create agreement in even the most difficult situations -- from family conflict to, perhaps, the Middle East. (Filmed at TEDxMidWest.)

Jason Fried has a radical theory of working: that the office isn't a good place to do it. In his talk, he lays out the main problems (call them the M&Ms) and offers three suggestions to make work work. (Filmed at TEDxMidWest.)

What do you think of people in poverty? Maybe what Jessica Jackley once did: "they" need "our" help, in the form of a few coins in a jar. The co-founder of Kiva.org talks about how her attitude changed -- and how her work with microloans has brought new power to people who live on a few dollars a day.

In her talk, Melinda Gates makes a provocative case for nonprofits taking a cue from corporations such as Coca-Cola, whose plugged-in, global network of marketers and distributors ensures that every remote village wants -- and can get -- a Coke. Why shouldn't this work for condoms, sanitation, vaccinations too? (Filmed at TEDxChange.)

Christien Meindertsma, author of "Pig 05049" looks at the astonishing afterlife of the ordinary pig, parts of which make their way into at least 185 non-pork products, from bullets to artificial hearts.

After hitting on a brilliant new life plan, our first instinct is to tell someone, but Derek Sivers says it's better to keep goals secret. He presents research stretching as far back as the 1920s to show why people who talk about their ambitions may be less likely to achieve them.
