Is Any Publicity Good Publicity? Media Coverage, Party Institutions, and Authoritarian Power-Sharing
Existing literature identifies nonofficial media as a tool for rulers to gather information from below. We argue that such media also help identify threats among elites. Motivated by profit, partially free media tend to cover politicians who challenge implicit norms of the regime. These political elites are perceived as threats to the power-sharing status quo, which leads peers to sanction them. We test this argument with evidence from the Chines…
Term Limits and Authoritarian Power Sharing: Theory and Evidence From China
Term limits that effectively govern leadership transition play an important role in authoritarian power sharing. A fixed term and a pre-appointed successor – two crucial components of term limits – credibly commit the incumbent ruler to share power with other elites, and also allow the elites to monitor and coordinate against the ruler's transgression of the power-sharing agreement. While the successful adoption of term limits often requires an e…

Popular Threats and Nationalistic Propaganda: Political Logic of China’s Patriotic Campaign
Conventional wisdom suggests that authoritarian leaders use nationalist propaganda as a tool to strengthen mass support. Yet few studies have provided systematic evidence to account for specific tactics underlying these information manipulations. We argue that autocrats, recognizing the material costs of propaganda, are more likely to target localities with the greatest antiregime potential. Using a unique dataset of “patriotic education sites” t…
Partnering with the State: Historical Legacies, the Local State Sector, and Foreign Direct Investment in China

Vote Buying as Rent Seeking: Land Sales in China’s Village Elections
What explains why vote buying occurs in some elections but not others? The phenomenon of vote buying is under-studied in authoritarian, single-party-dominant regimes, especially in non-partisan elections in which competition is candidate-centered rather than party centered. Village elections in China provide a valuable window on the dynamics of vote buying in these conditions. Employing both an in-depth case study and an original, panel survey to…
Riding on the power of the masses? How different modes of mass mobilization shape local elite bargaining in China
When local bureaucrats in China disagree with their superiors, official channels for achieving a policy revision are limited and generally ineffective. However, if the stakes involved are high, they may turn to the power of the masses and draw on public pressure to enhance their negotiating position. In such informal inter-bureaucratic bargaining, local officials might intentionally facilitate popular protest and lead to a situation we call 'mobi…
