Today, fewer than three in ten American teenagers are able to find summer jobs. These figures have fallen off particularly quickly since 2000, and the number of 16- to 19-year-olds at work is at its lowest since World War II. Older workers, immigrants, and young college grads are now taking the low-level work formerly filled by America’s teenagers, and economists have suggested that this change might be permanent.

It's a fact: Our workforce is shrinking. And as it shrinks, the unemployment rate is also shrinking. Critics of President Obama have been quick to say the president hasn't actually created jobs — the falling unemployment rate just means fewer people are trying to find work. If the job growth is an unreliable figure, and the unemployment rate is an unreliable figure, how do we measure economic change?

Things have changed since the 1970s, especially for women. But a new study published this week in the National Bureau of Economic Research indicates that those changes may not be making women more content. In fact, the research reveals that women are less happy now then they were in the 1970’s. With all the gains that women have made in the past three and a half decades, why is happiness on the decline? The Takeaway talks to the co-authors of the paper, “The Paradox of Declining Female Happiness", Justin Wolfers and Betsey Stevenson. Both are assistant professors in public policy at the University of Pennsylvania’s Wharton School of Business.
