Beyond outbreak zones: how Ebola shaped governance and trust across Sierra Leone Open Access
Lippe, Larissa (Spring 2026)
Abstract
This paper examines how the 2014–2016 Ebola epidemic affected political trust and governance perceptions in Sierra Leone, using a difference-in-differences design that compares citizens in chiefdoms with varying levels of Ebola exposure before and after the crisis. I test two competing theoretical mechanisms: a capacity hypothesis, which predicts that chiefdoms receiving greater emergency aid inflows would experience smaller trust declines, and an oversight hypothesis, which predicts that the crisis would produce a nationwide accountability shock independent of local exposure intensity. Drawing on Afrobarometer survey data from pre and post crisis periods, I find consistent support for the oversight hypothesis. The difference-in-differences estimator is statistically insignificant across all outcomes. These results suggest that the political consequences of the crisis were driven not by the geographic distribution of resources but by a nationwide disruption to the accountability structures through which citizens normally evaluate their government.
