In 1989, a health clinic in the town of Gävle, instituted a program to subsidize birth control pills for young women, so they would be able to afford to use it regularly. It led to fewer teenagers getting abortions, and more counties followed suit. The reasoning was that what they spent in subsidies, they could make back by having to pay for fewer abortions. But over the long term, subsidizing the Pill appears to have had some other benefits, and perhaps not on the people you might expect.
Andreas Madestam, assistant professor of economics at Stockholm University, has been researching the results of the experiment that began in Gävle and spread, and explains to Radio Sweden what he has found.
