Work in Progress

  • Liberalizing the Airwaves in Ghana: A Dynamic Model of Radio Station Competition
    Ghana liberalized its radio broadcasting sector in 1992 to allow the entry of commercial stations, where previously the state had a monopoly. I consider the role of the broadcasting regulator in affecting commercial stations' decisions to enter and the resulting effects of coverage spillovers in rural areas. Using entry data of all radio stations, I estimate their coverage areas to construct a dataset of which stations are available at every point in the country. I estimate a dynamic model of entry for commercial stations who face competition from commercial and public stations, measured by the overlaps of the stations' coverage areas. The model incorporates spillovers across the country through the network of overlapping coverage areas. To study the effects of radio, I exploit random variation in coverage caused by coverage spilling through gaps in mountainous areas. With this, I estimate the effect of coverage on night lights using a geographic regression discontinuity. I also combine the radio coverage data with Demographic Health Survey data to explore the effect of radio entry on mosquito bed net usage, as malaria is the leading cause of mortality in Ghana. I then use the structural model to evaluate the effects of alternative regulations on transmitter strengths and broadcasting fees on entry in rural areas, which would increase the positive externalities of radio.
