A new study says money can buy happiness, despite the conventional wisdom that says it can't.
A research team from the Harvard Business School surveyed more than four-thousand people in the U.S., Canada, Denmark, and the Netherlands.
The researchers asked people whether they paid others to do daily tasks they didn't enjoy so they could increase their free time.
Twenty-eight percent said they did and what they gave up in cash they gained in happiness.
They reported feeling less stress and being more satisfied with their lives than people who didn't trade money for free time.
The study is published in Monday's edition of the "Proceedings of the National Academy of Sciences."
