Mass Media and Contraception Use: An Experimental Test of Modernization Theory in Burkina Faso

This paper tests whether the arrival of mass media triggers a decline in fertility, a central prediction of modernization theory. Using a field experiment, we vary exposure to mass media and its content in a quarter of Burkina Faso. We provide radios to 1,600 women without previous access to mass media. Half live in status quo areas and half in areas where the local radio station was randomly selected to air a science-based family planning campaign. Contrary to modernization theory and previous literature, gaining access to status quo mass media decreases contraception use by 14 percent and reinforces traditional gender norms. In contrast, receiving a radio in campaign areas boosts contraception use by 16 percent. The campaign also led to a 9 percent reduction in births and a 0.3 standard deviation increase in reported welfare. Reduced belief in misinformation rather than shifts in attitudes and preferences drives the result.
