The effects of cellphone coverage expansion on wealth and political behavior
Taking advantage of Ghana’s gradual extension of cellphone towers in the early 2000s, we analyze the wealth effects of cellphone coverage expansion in a developing country setting using a difference-in-differences (event study) research design. We proxy local wealth using night-time light density over 1996–2016 and an asset ownership-based index from the 2000 and 2010 censuses.
