Economists Melissa S. Kearney, who has appeared on this blog and our podcast before, and Phillip B. Levine have a new NBER paper (abstract; PDF) that looks at the influence of MTV’s reality-TV show 16 and Pregnant on teen pregnancy. Levine explained the study’s assumption to The New York Times:
Ms. Kearney and Mr. Levine examined birth records and Nielsen television ratings, finding that the rate of teenage pregnancy declined faster in areas where teenagers were watching more MTV programming — not only the “16 and Pregnant” series — than in areas where they did not. The study focuses on the period after “16 and Pregnant” was introduced in 2009 and accounts for the fact that teenagers who tuned in to the show might have been at higher risk of having a child to begin with.
“The assumption we’re making is that there’s no reason to think that places where more people are watching more MTV in June 2009, would start seeing an excess rate of decline in the teen birthrate, but for the change in what they were watching,” Mr. Levine said.
The authors found that the show “led to more searches and tweets regarding birth control and abortion, and ultimately led to a 5.7 percent reduction in teen births in the 18 months following its introduction. This accounts for around one-third of the overall decline in teen births in the United States during that period.” Read More »
Back in 2010, we put out a two-part podcast (Part 1; Part 2) about Prize-Linked Savings (PLS) plans, which combine the safety of a savings account with the thrill of a lottery payout. It is one of the most intriguing ideas we’ve run across in some time. Maybe not earth-shattering, but potentially an important way to help people save more money.
Now a group of scholars (including the University of Maryland economist Melissa Kearney, who was featured in the podcast) have put out a working paper (abstract; PDF) that set up experiments to determine whether a PLS plan would actually induce better savings behavior. Their answer is yes. Read More »
