Soap Operas and Fertility

J sent me this article from Foreign Policy entitled "Are soap operas a form of birth control?" The article refers to a new working paper by economists entitled Soap Operas and Fertility: Evidence from Brazil, by Eliana La Ferrara (Bocconi University and IGIER), Alberto Chong (Inter-American Development Bank), and Suzanne Duryea (Inter-American Development Bank). Here's the abstract for what seems like an interesting paper:
"Abstract

What are the effects of television, and of role models portrayed in TV programs, on individual behavior? We focus on fertility choices in Brazil, a country where soap operas (novelas) portray families that are much smaller than in reality. We exploit differences in the timing of entry into different markets of Rede Globo, the network that has an effective monopoly on novelas production in this country. Using Census data for the period 1970-1991, we find that women living in areas covered by the Globo signal have significantly lower fertility. The effect is strongest for women of lower socioeconomic status and for women in the central and late phases of their fertility cycle, consistent with stopping behavior. The result is robust to placebo treatments and does not appear to be driven by selection in Globo entry. Finally, we provide suggestive evidence that novelas, and not just television, affected individual choices. First, people living in areas covered by the signal were more likely to name
their children after novela characters. Second, entry of a network that relied on imported shows did not have a significant impact on fertility.
The abstract suggests they are cognizant of possible selection issues related to television entering markets, and check for whether that is driving their results, plus find some interesting second order evidence that could be construed as supporting their main findings. Like, that they named their kids after the soap opera characters. That's a really interesting finding. I'll read the paper today and may blog about it later.
