Decentralized propaganda in the era of digital media: The massive presence of the Chinese state on Douyin

American Journal of Political Science, EarlyView.
Abstract The rise of social media in the digital era poses unprecedented challenges to authoritarian regimes that aim to influence public attitudes and behaviors. To address these challenges, we argue that authoritarian regimes have adopted a decentralized approach to produce and disseminate propaganda on social media.

The political consequences of Africa's mobile revolution

American Journal of Political Science, EarlyView.
Abstract What are the political consequences of rising domestic connectivity? I study this question in Sub‐Saharan Africa, asking how mobile technology shapes public opinion in geographically isolated communities. For remote rural populations, mobile devices increase contact with physically distant social networks, through regular phone calls with ...
