Cell Phone Access and Election Fraud: Evidence from a Spatial Regression Discontinuity Design in Afghanistan

This paper examines the impact of cell phone access on election fraud. I combine cell phone coverage maps with the location of polling centers during the 2009 Afghan presidential election to pinpoint which centers were exposed to coverage. Results from a spatial regression discontinuity design along the two-dimensional coverage boundary suggest that coverage deters corrupt behavior. Polling centers just inside coverage report a drop in the share of fraudulent votes of 4 percentage points, while the likelihood of a fraudulent station decreases by 8 percentage points. Analyses of the effect of coverage on citizen participation in election monitoring, election-related insurgent violence, and the tribal composition of villages suggest that the observed declines in fraud are likely attributed to cell phone access strengthening social monitoring capacity.
