Violence and Election Fraud: Evidence from Afghanistan

The study examines how insurgent violence influenced electoral manipulation during Afghanistan's 2009 presidential election. Using a forensic 'last-digit' test validated by a physical recount, the authors find an inverted-U shaped relationship: moderate violence increases fraud by limiting the presence of election observers, but extreme violence decreases fraud by disrupting the loyalty networks required to manipulate results. The analysis further distinguishes between the incumbent and the challenger, finding that the challenger's fraud exhibits 'spatial displacement'—shifting to neighboring districts when local violence is too high—whereas the incumbent's fraud, tied to official state apparatus, does not.

• The relationship between political violence and election fraud follows an inverted-U shape, where fraud increases as violence rises to a moderate level but decreases when violence becomes extreme.
• Moderate levels of violence facilitate fraud by creating zones of insecurity that limit the ability of international and domestic election observers and media to monitor the process.
• Extreme violence suppresses fraud because it disrupts the loyalty networks needed to bribe officials or reach polling stations, and removes incentives for candidates to allocate resources to areas where elections may be completely interrupted.
• Fraud perpetrated by the challenger (Abdullah Abdullah) exhibits spatial displacement, meaning that while local violence reduces fraud, high violence in adjacent districts increases the likelihood of fraud in a given location.
• Fraud perpetrated by the incumbent (Hamid Karzai) does not show spatial displacement because it relies on static networks of appointed officials tied to specific administrative jurisdictions.
• The 'last-digit' forensic measure, which detects non-random patterns in reported vote totals, was successfully validated against a physical recount of 342 ballot boxes conducted by the Independent Election Commission.
• The study concludes that the majority of election fraud in the 2009 Afghan election was committed in favor of the incumbent, likely due to the close relationship between government officials and the election commission.
